I'm your host Brian Bienkowski, editor of Agents of Change, and senior editor at Environmental Health News. Folks, we are so grateful for your support. We've been at this a few years now and we would love to continue to grow. Please share this podcast with your family and friends, colleagues, and subscribe to us on Spotify or iTunes and please leave us a review. Today's guest is Dr. Maria Jose Talayero Schettino, a current fellow and a doctorate pH candidate in the Department of Environmental and Occupational Health at the George Washington University. Maria talks about switching careers from a physician to an environmental health researcher, using her research to advocate for environmental justice in her native Mexico and how the medical field can better prepare doctors to understand the effects of environmental pollutants on our health. Enjoy. All right, I am now joined by Dr. Maria,Jose Talayero Schettino. Maria, how are you doing today?Maria Jose Talayero Schettino 01:14I'm doing great. Thanks for having me here. Brian, how are you?Brian Bienkowski 01:18I am doing wonderful. And I'm really excited to hear about all the work that you're doing. But I want to start at the very beginning. Tell me about growing up in Mexico City.Maria Jose Talayero Schettino 01:29Oh, yeah, I honestly have very good memories about growing up in Mexico City. But I'm not sure how familiar you are with Mexican culture or if you've ever traveled there, butBrian Bienkowski 01:41almost zeroMaria Jose Talayero Schettino 01:42Mexicans really highly, highly value things like hospitality, generosity, respect for elders, solidarity. And it might sound really funny, but we highly value social connections and gatherings. I mean, it's weird to say that we really value parties, but we do. And that's why our food and culture is so important. So I feel like growing up in Mexico City was just like that: full of culture, tradition, family gatherings. And I feel like I'm very lucky to be able to call myself Mexican.Brian Bienkowski 02:12Is there a certain food or or holiday or gathering? Are there certain ones that kind of stick out in your mind as being particularly poignant?Maria Jose Talayero Schettino 02:22I mean, yes, I think so. Particularly, Independence Day. I have very good memories about going to watch the fireworks. Independence Days in September. Most people in America think it's Cinco de Mayo. But that's not it. It's in September. But other holidays that really stick up for me are the other mortos which is in November, and also Posadas, which are held during like, December. So Christmas is very important to us too.Brian Bienkowski 02:54And the only thing I really know about Mexico City, and pardon my American ignorance, is it's it's a massive city, right? I mean, were you in kind of a dense urban area?Maria Jose Talayero Schettino 03:04I mean, yeah, it's a huge, huge city. And I feel like there's a lot of people living around Mexico City, I did feel like I lived with my family in one of like, more suburban area, not closer to like, the historical center or anything. But we travel a lot by car. I mean, we have a huge air pollution problem because of that. But I feel like yeah, it's a huge city, and everyone's all around it in. I mean, it's very, very well connected when it comes to streets, we have a lot of traffic, but that's how people go around Mexico City by staying in traffic for really long periods of time.Brian Bienkowski 03:48So how and when did you become interested in health and the environment?Maria Jose Talayero Schettino 03:53I mean, this is a great question. And every time I get it, I wish I had that story, "like when I was younger, I used to tell my parents that I wanted to be a doctor since I was a little girl." Unfortunately, that was not me. I wanted to be a singer. I wanted to be an artist. I wanted to be a painter. So that was not me. So I think I ended up in like healthcare and the environment because I really loved science. And don't get me wrong, I really hated physics and math. So because they hated it, I feel like that drew me into chemistry and biology. And I I think I ended up in medical school because of that, because my love for science and honestly, I never knew I was gonna end up doing research and doing a lot of statistics. Even after I ran away from math.Brian Bienkowski 04:42The only class I ever got to see in growing up was chemistry that that that for some reason that subject gave me such fits. And I don't know if it was my teacher, or what but it really bothered me.Maria Jose Talayero Schettino 04:54I mean, yeah, it's a really, really hard, hard subject! and I I feel you I feel like I just don't know, I don't know what it was. But chemistry and biology always caught my eye.Brian Bienkowski 05:05eye. And the weird thing is now I, you know, I've spent most of my career writing about chemicals in the environment. So it's, it's strange, I hope I'm not just writing a bunch of incorrect things.Maria Jose Talayero Schettino 05:17I guess I guess you've made peace with it. And now you love it.Brian Bienkowski 05:21That's right. So before we get into your your career has been fascinating because you, you started off in healthcare as a physician, and I want to talk about your journey. But first, what is a moment or event that has helped shape your identity?Maria Jose Talayero Schettino 05:35Wow, that's a really hard question. I think there are a couple of things that I want to mention that really shaped my identity as I was growing up. And I feel like the first one was really practicing medicine in public hospitals, that really showed me that life is not fair. And that made me want to work on that. And I think the other thing I want to mention that really shaped my identity is immigrating to the United States, even though I emigrated when I was, I think, 26 years old. Even though I'm like a short four-hour flight away from home, I think immigrating made me realize about all the things that I took for granted, and now I really highly value.Brian Bienkowski 06:16Luckily, we're going to talk about both of those things. Because I think that's, it's a really important part of your journey. And starting with this idea of you became a physician in practice in rural communities around Mexico City. So can you tell me about this work, what you learned from this time with patients and why ultimately, you decided to switch careers?Maria Jose Talayero Schettino 06:34Of course. So I guess, practicing medicine in rural communities, and even public hospitals, or public health care centers in Mexico, it really does feel like an art. Because you need to learn how to treat disease differently. Sometimes the medicines that you learn on a book that were the best for a specific disease are not available. So you have to work around it. And the same comes for like diagnostic diagnostic tools, you don't have fancy equipment, or even sometimes you don't even have basic equipment to make a diagnosis. So you have to really focus on talking to the patient. And that's the only thing that you often have, and you have to learn how to practice medicine with that, which is the only thing that you have. And I think when it comes to the change that I made from like, a very clinical-practice-based career into like an research and an environmental one is that one of the things that frustrated me that most while I was practicing medicine is that there were and there are still a lot of things that we do not have answers for in patients. When they come to get a diagnosis, they sometimes ask you were themselves like why something happened. And most of the time, we really have to say that we don't know why. I think there's even a medical term for this, which is that something it's adiabatic, which means that we have absolutely no idea what costed and I really hated it. I hated not being able to have answers for my patients. And I mean, I still don't have all the answers. But I think as I moved forward into an environmental health career, I realized that this field of environmental health had a lot of those answers. And that through my medical education, I barely heard of those. So I think that's what made me shift.Brian Bienkowski 08:18So we're going to talk more about your your research and that switch. And, you know, maybe some ideas you have for the medical field to bridge some of these gaps. But I have to ask, did your did family and friends question your decision? I mean, being a physician is a is a career that I think most of us know. I mean, we all know that career. It's familiar to us. It's a pillar in most communities. And I think researcher is a little more esoteric to a lot of folks. So I'm wondering if your family was like, What are you doing?Maria Jose Talayero Schettino 08:48Oh, my gosh, yeah, I every single person that went through medical school with me or even my family, or even friends, or even now that I meet people, when I tell them that I went through medical school and that I became a physician. Now I do environmental health, every single person has questioned that. And I feel like sometimes, when like for the Mexican perspective, a lot of people questioned this because they don't really know much about the field, and how important it is. But I don't know like having all these people question your life decision makes it like just harder to move forward and harder to realize if you're in the right path. And I think that was really hard when I first made the decision to switch. But now looking back, I don't think I would do anything differently.Brian Bienkowski 09:38And to keep on this theme of challenges. I want to reflect a bit on your move to the US. You mentioned how important Mexico City and family and gathering was to your, to your upbringing and identity. And I don't know that most folks understand the toll of immigrating even under positive circumstances like yourself. So can you talk about this experience and what people should know about the personal channel changes and sacrifices for immigrants?Maria Jose Talayero Schettino 10:02Yeah, honestly, thanks for asking this questions. I think that sometimes the challenges for like immigrating in good, some good circumstances, like I did is invisible to others. But from my experience, I really want to say that immigrating in good circumstances to the US is extremely challenging. There are so many rules and steps that you need to take that often really don't even make sense and can really make your life harder. But I do have to say that I'm really fortunate to be here. And I'm really grateful to the US for the all the all the opportunities that I've had. But moving away from family is so hard. Like you move to a country where you don't have this support system, the culture is extremely different. And you need to talk and communicate using a different language. I don't know if you've watched Modern Family. I really like that show. But there's this episode.Brian Bienkowski 10:54Modern Family? Yeah, gosh, yes. I'm a yes. I'm rewatching it right now. Yes.Maria Jose Talayero Schettino 10:59I love it. I love it. But there's this episode, where Sofia Vergara says, "do you know how smart I am in Spanish?" And it's so funny. But it's so relatable. Like, there's so many things that I want to say, but I just cannot find the words.Brian Bienkowski 11:13Well, thank you so much for sharing that. And I want to talk now about the work that you're doing as you've made the switch to research. So you're examining environmental exposures, and birth defects in Mexico. That's one of the things you're working on. So I wanted to talk about talk, you know, if you can explore this link between these exposures and birth defects, why it's concerning, and who is most impacted?Maria Jose Talayero Schettino 11:34Of course, yeah. So through my dissertation, I'm on the final stages of my doctoral program, hopefully graduating this August. But through my dissertation, I've been studying birth defects and their relationship that they have with the polluting industry in the country, in Mexico. It has been challenging to do something like this with public databases that the Mexican government has, but I found really interesting things. For example, I've seen that the reporting for genital birth defects in Mexico in the last couple of years has been steadily increasing. I mean, this could be due to so many things –like people know now how to recognize them better or many other things. But when you compare that to other countries, this seems to be happening, too. And it's making us think about the impact endocrine disrupting chemicals are having in communities around industrial areas. I think it is very concerning to see the impact that pollution has in your health even before you were born. Like I don't think people realize that we used to think in a medical field that that placenta was like this major barrier where nothing could go through it. But we've realized that that's not the case. And I really think that we don't have strict enough regulations for most chemicals. But overall, like if you asked me like, What was the most concerning thing that you saw is the lack of data that Mexico has for both health effects and polluting chemicals. I'm always amazed that countries like the US, for example, like researchers in the US say that they are so far behind, but they don't really realize if they're far behind where developing countries are.Brian Bienkowski 13:11You mentioned a term their endocrine disrupting chemicals, which I think a lot of Environmental Health News readership is aware of. But for our listening audience, can you explain what those chemicals are? And kind of the plausible ways that they could possibly be behind some of these birth defects?Maria Jose Talayero Schettino 13:26Of course, yeah, sorry, I forgot to explain that! But yeah, endocrine disrupting chemicals are generally what we say are chemicals that are capable of interfering with the way your hormones work. And your hormones are very important since the beginning of life, because hormones are also chemicals, but they mediate a lot of processes in your body. So if there's a chemical there's interrupting those pathways, then you can see problems with your development or the endocrine system diseases, for example, reproductive issues, or diabetes, or thyroid problems. So mostly, those are the things that we're concerned when we get exposed to endocrine disrupting chemicals, which are almost in everything. But one of the major things that we know, gets us exposed to endocrine disrupting chemicals, are plastics.Brian Bienkowski 14:21Soyou mentioned gaps in the research. And you noticed this pretty early on that there were some gaps in environmental health and environmental justice data in Mexico. And I know you're just one researcher, but can you talk about this dearth of research and how you're trying to tackle this?Maria Jose Talayero Schettino 14:35So I feel like environmental justice has been overlooked for centuries in both the community scale and the global scale. I really don't think high income countries realize how all their decisions impact developing countries. For example, I remember a few years ago, there was this Super Bowl held in Arizona or one of the border, one of the border states, but I think it was Arizona. And they said that they weren't going to have have a zero-waste Super Bowl because all the plastic generated was going to be recycled. But that plastic was shipped to Mexico, to northern Mexico, where plastic recycling plans are polluting the water and air of Mexican communities. So is one of the of the issues that we see in the global health realm. Like, this is not something that only happens in Mexico, but it happens everywhere. But with things like in the country level, when I first started the process to find something I wanted to do for my dissertation, I remember talking to my chair, about wanting to do something on environmental justice. So I started doing research on what was out there. And unfortunately, I wasn't able to find much. And I think this is related to what I was talking about, that we don't have a lot of data. And there's also something going on in Mexico and you know, other Latin American countries like Colombia, where it's very dangerous to be in environmentalist in those countries. Mexico is one of the deadliest country to be an environmentalist. So advocating for these things can get really challenging.Brian Bienkowski 16:03So can you talk about your efforts, in particular to advance environmental health policy in Mexico, including on lead and criminal behavior? And can you talk a little bit about your involvement with Mundo Químico, boy, I'm probably butchering these words. I'm really smart English, I swear. And what have you learned? And have you had any victories along the way in your in your efforts to advance environmental health policy down there?Maria Jose Talayero Schettino 16:28Yeah, so let me talk a little bit about what Mundo Químico is, which translates to chemical world because we live in a chemical world. So this Mundo Químico is like a collaborative of scientists and other professionals in Mexico that got together and are really trying to push programs and policies related to environmental health in the country. Honestly, I feel like I'm very lucky to be part of it. I am the youngest member. And I ended up being there because as I was finishing up my master's program, I always felt like I owed something to my country, and I needed to do something in Mexico. So I did some research and who was working on environmental health in the country. And I found this very big and famous scientist, his name is Dr. Carlos Santos Burdoa. He's US-based. He was at the George Washington University, when I first heard of that of him. So I email him. Honestly, I didn't expect a reply, because like, senior scientists are really busy. But I did get a reply. And I was really surprised. But he told me that he was building this collaborative called Mundo Químico, and he asked me if I wanted to join him. So of course, I said, Yes. So what we've been trying to do, as I was saying, is to push environmental health agenda into the policies and to do some programs to reduce environmental health exposures. And we started with lead exposure, because Mexico has a really big problem with lead. I think we've done different things that I don't think I have enough time to talk about during our podcast. But what I have learned, and I think I have learned a lot of things, but one of the most important ones, is that it is so hard to communicate to the public and with policymakers. And I really did not expect that when I started my career in environmental health. And I think that's how I ended up studying lead exposure and criminal behavior. Because often when you want policymakers to listen to what you have to say, you have to talk to them in their terms, and talk to them in topics that that you feel that they will prioritize. So we know crime is a big thing in Mexico. So what we did is where we viewed all the available evidence to see how lead exposure was related to criminal behavior, we found that there's a link. But we still need research on this. And we need research to understand what the relationship means in the Mexican context. But yeah, I feel like that's how it started because we need to learn to communicate with policymakers. And I really don't want to stop talking about this question without mentioning some of the wins that we had, because I feel like in environmental health, we will always hear a lot about our fatals and not our wins. So we have had some wins, we have been able to produce some programs on lead exposure. And one of them is we were able to partner with WONART, which is an Arts Fund that the government of Mexico has and through their through them, we've been able to push this program to train pottery workers to produce lathe, Clay ceramics, which are a major traditional thing in Mexico and they usually have led in it. But we're pushing this program to produce lead-free clay ceramics and to certify that they're lead free. And even though we still have a lot of work to do on that issue, the start of the program to me is just a great win.Brian Bienkowski 19:54You mentioned two things there that I have a follow up on and you started to get to it a little bit at the end is is you meantioned that lead exposure is a big issue in Mexico. And I'm wondering if you can just kind of give a brief overview of the ceramics and potentially other sources of lead in the environment there. And then second, if you can kind of walk us through why there's this possible link to crime, what does lead do to people that could make them more susceptible to committing crime?Maria Jose Talayero Schettino 20:20Of course, yeah. So I'll start with at glaced clay ceramics. So in Mexico, we use traditional pottery for cooking, storing, or even serving food. And one of this traditional pottery is called glaced clay ceramics and the glaze that the ceramics have, it has lead in it. And because it's not produced in ovens, that can reach high enough temperatures, in like close ovens, because it's a very artisanal process, the lead stays there, and it leeches into food. And he usually leeches when you like cook, or store food that's very acidic. And Mexican cuisine is really acidic. So it leaves us a lot of lead. And we have a major problem of lead exposure. Because of that, that's actually the main source of lead exposure in the country, because most of the people in Mexico use it. Like if you go down there, you'll see it in restaurants, you'll see your honestly see it everywhere. And the latest numbers show that children from one to four ages in Mexico, 17% of all children from one to four years of age in Mexico have lead poisoning. So it's a really public health issue, we don't have data to see if older kids have lead, we don't have data on adults. But it's a really big concern, because lead is very toxic, like the WHO says that there is no safe level of exposure to lead because of how toxic it is. And he causes a variety of things. It can increase cardiovascular disease, it can damage the kidneys. But one of the ones, one of the things that we have studied the most is how it damages the nervous system and the brain. And this goes back to the question that you asked about criminal behavior. So we've seen that lead damages the prefrontal cortex of the brain, which is in charge of, of behavior, and, yeah, to put it in, like, easier terms, yeah, it's in charge of behavior and how you react to things. So when it damages the neurons there, it can cause antisocial behavior, and it can cause aggressiveness, and it can cause violent behaviors. So that's how we've seen it has associated with criminal behavior. So in addition to that communication work directly with policymakers and residents, I know you're also active on social media. And I'm wondering how you've leveraged those platforms to try to get the word out on some of these environmental ills. Oh, my gosh, being on social media is so hard. I don't know if you've tried it. But seriously, it takes a lot of effort to create content on social media. But yeah, so I ended up in social media, because going back to this environmental justice issues, Spanish speaking countries, and communities really don't have as much information as English speakers do. And that's something I really noticed while I was scrolling down on every social media platform, so I saw hundreds of videos on how to reduce environmental exposures, but almost none, were in Spanish. So I decided to venture into social media. And honestly, I don't have that many followers, my platform is growing. But one of the things that I've noticed is that many health professionals are starting to follow me because they're interested. And they want to learn more, because some of their patients are asking about these topics. So I feel like it's a great way to do outreach and communication, things when you're in the environmental health field.Brian Bienkowski 24:06I have not tried it. Of course, I had I had social media accounts. It's been more than a decade. I think since I've had one, I don't even have LinkedIn anymore. I am really happy that people like you are on them, because I think it is a counterbalance to the reason that I got off, which is a lot of kind of miss information and hatred. But it is really heartening for me to see folks like yourself and scientists in general and health professionals are able to take their message directly to people as opposed to kind of being mediated through, you know, newspapers or whatever happened back in the day. So I think that's a good thing. And we have noticed though, as a newsroom, a lack of Spanish language environmental content and information and we are trying to trying to combat that with some eh en español coverage. So We have noticed the same thing as you. And there is a real language justice issue in the United States when it comes to environmental information. So I hope people will follow you. We will add a link in this podcast article so people can follow you if you want. Having spent some time now in the environmental health research field, and we were talking earlier about how you started as a physician, how do you think the medical field could better incorporate environmental health information for patients and prepare those physicians?Maria Jose Talayero Schettino 25:28I mean, I honestly wish health care workers have better training in environmental health. From my experience, which is going through medical school in Mexico, I really can't speak for other countries. I barely heard about environmental exposures as causes of disease, when I was in medical school, maybe I heard about asbestos or silicosis or occupational exposures, but non an environmental exposures like a social determinants of health, which they are. So I'm currently working actually on a project with some peers on how there is a huge gap in medical and other other healthcare professions school curriculum when it comes to environmental health in Latin America. And it is a sad reality that we barely see courses on environmental health in these curriculums. But I can tell you that I like I can see myself advocating about this for a really long time. And I think we need to get to a point where every single doctor, every single dentist, every single nutritionist, every single nurse knows that this exists, and that we need to know about it and talk to our patients about it.Brian Bienkowski 26:41This is purely anecdotal. But I do feel like I'm seeing more on the climate side of things where physicians are being more active and perhaps more trained in climate change and extreme heat, but less so on –surprisingly– less so on things like chemical exposure, and the things that you've been talking about endocrine disrupting chemicals. So hopefully, hopefully, that changes because I think that would be a real public health win. So, Maria, this has been so much fun hearing about you and your work. And I have to ask you, before we get to some of the fun questions, I have a couple more questions. And one is do you plan on going back to Mexico? Would you want to work there? Or do you think you'll stay in the United States? What do you want to do with this environmental health research training?Maria Jose Talayero Schettino 27:25Oh, my gosh, you're putting me on the spot.Brian Bienkowski 27:28I mean, you can have a no comment.Maria Jose Talayero Schettino 27:30I know my family's gonna want me to give an answer that maybe it's not the one that they like. But I do feel that the work that I'm doing for Mexico in the United States, is far like, I feel like I have way more opportunities to do something for my country from the United States, than the ones that I see that are my country. And it's a really sad reality, because I would give the world to just go back to my family and my nephews. But if I really want to see a change, I really feel like I have to stay in the United States for at least a couple of years. To improve, like my research techniques to get a better sense of what's out there and what I can do for Mexico. I mean, in the future. I don't know how long from from now, I do see myself going back to Mexico at some point. But right now, I don't think it is an option. And it is a sad reality, not only for me, but for other immigrants that are doing science in the United States, because our countries lack opportunities.Brian Bienkowski 28:39And Maria, before we get to the fun stuff, what are you optimistic about?Maria Jose Talayero Schettino 28:44Oh, that's a really important question! I feel like we don't hear about optimism sometimes in the environmental field, like there are so it's filled with bad news sometimes. But I feel like I'm optimistic about hearing more people are learning about environmental exposure. So how they can affect their health, because honestly, sometimes social movements can move policies faster. So we really need that. I'm optimistic about how younger generations are thinking more about the environment now. And they're joining this fight. There are so many things I'm optimistic about. And I'm glad you brought this up. Because again, I don't think that this field is full of good news. So we need to, to have these victories and these things that we're optimistic about really present in our day to day because he can get overwhelming at times.Brian Bienkowski 29:37I think the hard thing in my profession and maybe this is true in science in science communication as well, is whenever we try to talk about good news, it often feels like we're perhaps greenwashing or perhaps we're overlooking, you know, renewable energy is a great example. You know, solar energy and wind energy are less polluting, however now we have to go get those chemicals to make those panels in the ground and community. You know, so there's always there's other problems and we don't want to overlook those. But I totally agree with you that we need to be better as a, as a country in general about celebrating environmental wins, so people just don't get so down about it.Maria Jose Talayero Schettino 30:17Yeah, cuz I mean, when I talk to people about toxic exposures, I usually get the same reaction, like, everything's toxic, I'm gonna die from something. So I might as well just stop thinking about this. And I don't think that's a great approach. So, I mean, that should go back to our communication efforts, like, what are we saying, what are we doing? And how can we make this better? So our message gets out there, and it's not as overwhelming as it is currently.Brian Bienkowski 30:43100% totally agree with you. Well, Maria, thank you so much for your time. I'm just so I'm so happy to have met you and have you in this program. I'm just really excited about the work you're doing. So before I get you out of here, I have a few rapid fire questions where you can just answer with a one word or a phrase, if I have a whole day off, I am likely.Maria Jose Talayero Schettino 31:05Oh my gosh, I'm probably hitting the craft store to find a new craft to doBrian Bienkowski 31:09What what type of crafting do you like do?Maria Jose Talayero Schettino 31:12anything, like anything like it, maybe it's knitting, maybe it's stitching, maybe it's painting, whatever, like, whatever is new, I'm doing it.Brian Bienkowski 31:22So my wife and I, we live in the Upper Peninsula. And so we have very long winters. And I find myself this time of year. And I hesitate to even say this pining for winter, because it is such a great time to be quiet. And I play I'm playing music and my wife does be beadwork and stuff like that. Or we do some paintings together. And it's all crafty, and it's cozy and quiet. And then in the summer, I find that I really miss those. I really missed those times. So I need to find a way to do more crafty things, when it's nice outside. Yeah,Maria Jose Talayero Schettino 31:54I can relate to that. 100% I feel like it's a great therapy to do craftBrian Bienkowski 31:58100%. Well, I just had a guest on who was the guest, I'm forgetting now. But I had a guest on we were talking crafts not too long ago, I'll have to dig that out. Because I think it's for folks like yourself who are really busy doing this kind of work. It's good to have that other side of your creative brain get used every now and then. So the best gift I've ever received isMaria Jose Talayero Schettino 32:22I'm gonna see my family.Brian Bienkowski 32:24And if I could immediately gain one talent or ability it would beMaria Jose Talayero Schettino 32:31I know, to be able to get grants for research without being rejected.Brian Bienkowski 32:37Not flight or invisibility, just just grants! this one good for research. keeping it simple. I like that. And you do not have to. You can talk more than one word or a phrase here. What is the last book you read for fun?Maria Jose Talayero Schettino 32:53Oh, this is a good one. So lately because I've been working on my dissertation. I feel like I've been reading a lot of science stuff. But I feel like the last book that I read it was, I feel it was last year. And it's a book by a Mexican Indigenous woman, well, Ilfrosina Cruz who is now a representative in the Mexican government. And it's a great book. I'm not gonna spoil it for everyone. But she talks about her life as an Indigenous girl and how she wanted something different. And she wanted to create opportunities. And she moved on to be a representative and changing the laws in Mexico. So it's a really inspiring book, and I highly recommend it, it is called "Los Sueños de la niña de la montaña," which translates to "The Dreams from the girl up the mountain. I don't know if it's available in English yet, but I know it's in Spanish and I really highly recommended.Brian Bienkowski 33:46Excellent. Well, Maria, thank you so much for your time today.

I'm your host Brian Bienkowski, editor of Agents of Change, and senior editor at Environmental Health News. Folks, we are so grateful for your support. We've been at this a few years now and we would love to continue to grow. Please share this podcast with your family and friends, colleagues, and subscribe to us on Spotify or iTunes and please leave us a review. Today's guest is Dr. Maria Jose Talayero Schettino, a current fellow and a doctorate pH candidate in the Department of Environmental and Occupational Health at the George Washington University. Maria talks about switching careers from a physician to an environmental health researcher, using her research to advocate for environmental justice in her native Mexico and how the medical field can better prepare doctors to understand the effects of environmental pollutants on our health. Enjoy. All right, I am now joined by Dr. Maria,Jose Talayero Schettino. Maria, how are you doing today?Maria Jose Talayero Schettino 01:14I'm doing great. Thanks for having me here. Brian, how are you?Brian Bienkowski 01:18I am doing wonderful. And I'm really excited to hear about all the work that you're doing. But I want to start at the very beginning. Tell me about growing up in Mexico City.Maria Jose Talayero Schettino 01:29Oh, yeah, I honestly have very good memories about growing up in Mexico City. But I'm not sure how familiar you are with Mexican culture or if you've ever traveled there, butBrian Bienkowski 01:41almost zeroMaria Jose Talayero Schettino 01:42Mexicans really highly, highly value things like hospitality, generosity, respect for elders, solidarity. And it might sound really funny, but we highly value social connections and gatherings. I mean, it's weird to say that we really value parties, but we do. And that's why our food and culture is so important. So I feel like growing up in Mexico City was just like that: full of culture, tradition, family gatherings. And I feel like I'm very lucky to be able to call myself Mexican.Brian Bienkowski 02:12Is there a certain food or or holiday or gathering? Are there certain ones that kind of stick out in your mind as being particularly poignant?Maria Jose Talayero Schettino 02:22I mean, yes, I think so. Particularly, Independence Day. I have very good memories about going to watch the fireworks. Independence Days in September. Most people in America think it's Cinco de Mayo. But that's not it. It's in September. But other holidays that really stick up for me are the other mortos which is in November, and also Posadas, which are held during like, December. So Christmas is very important to us too.Brian Bienkowski 02:54And the only thing I really know about Mexico City, and pardon my American ignorance, is it's it's a massive city, right? I mean, were you in kind of a dense urban area?Maria Jose Talayero Schettino 03:04I mean, yeah, it's a huge, huge city. And I feel like there's a lot of people living around Mexico City, I did feel like I lived with my family in one of like, more suburban area, not closer to like, the historical center or anything. But we travel a lot by car. I mean, we have a huge air pollution problem because of that. But I feel like yeah, it's a huge city, and everyone's all around it in. I mean, it's very, very well connected when it comes to streets, we have a lot of traffic, but that's how people go around Mexico City by staying in traffic for really long periods of time.Brian Bienkowski 03:48So how and when did you become interested in health and the environment?Maria Jose Talayero Schettino 03:53I mean, this is a great question. And every time I get it, I wish I had that story, "like when I was younger, I used to tell my parents that I wanted to be a doctor since I was a little girl." Unfortunately, that was not me. I wanted to be a singer. I wanted to be an artist. I wanted to be a painter. So that was not me. So I think I ended up in like healthcare and the environment because I really loved science. And don't get me wrong, I really hated physics and math. So because they hated it, I feel like that drew me into chemistry and biology. And I I think I ended up in medical school because of that, because my love for science and honestly, I never knew I was gonna end up doing research and doing a lot of statistics. Even after I ran away from math.Brian Bienkowski 04:42The only class I ever got to see in growing up was chemistry that that that for some reason that subject gave me such fits. And I don't know if it was my teacher, or what but it really bothered me.Maria Jose Talayero Schettino 04:54I mean, yeah, it's a really, really hard, hard subject! and I I feel you I feel like I just don't know, I don't know what it was. But chemistry and biology always caught my eye.Brian Bienkowski 05:05eye. And the weird thing is now I, you know, I've spent most of my career writing about chemicals in the environment. So it's, it's strange, I hope I'm not just writing a bunch of incorrect things.Maria Jose Talayero Schettino 05:17I guess I guess you've made peace with it. And now you love it.Brian Bienkowski 05:21That's right. So before we get into your your career has been fascinating because you, you started off in healthcare as a physician, and I want to talk about your journey. But first, what is a moment or event that has helped shape your identity?Maria Jose Talayero Schettino 05:35Wow, that's a really hard question. I think there are a couple of things that I want to mention that really shaped my identity as I was growing up. And I feel like the first one was really practicing medicine in public hospitals, that really showed me that life is not fair. And that made me want to work on that. And I think the other thing I want to mention that really shaped my identity is immigrating to the United States, even though I emigrated when I was, I think, 26 years old. Even though I'm like a short four-hour flight away from home, I think immigrating made me realize about all the things that I took for granted, and now I really highly value.Brian Bienkowski 06:16Luckily, we're going to talk about both of those things. Because I think that's, it's a really important part of your journey. And starting with this idea of you became a physician in practice in rural communities around Mexico City. So can you tell me about this work, what you learned from this time with patients and why ultimately, you decided to switch careers?Maria Jose Talayero Schettino 06:34Of course. So I guess, practicing medicine in rural communities, and even public hospitals, or public health care centers in Mexico, it really does feel like an art. Because you need to learn how to treat disease differently. Sometimes the medicines that you learn on a book that were the best for a specific disease are not available. So you have to work around it. And the same comes for like diagnostic diagnostic tools, you don't have fancy equipment, or even sometimes you don't even have basic equipment to make a diagnosis. So you have to really focus on talking to the patient. And that's the only thing that you often have, and you have to learn how to practice medicine with that, which is the only thing that you have. And I think when it comes to the change that I made from like, a very clinical-practice-based career into like an research and an environmental one is that one of the things that frustrated me that most while I was practicing medicine is that there were and there are still a lot of things that we do not have answers for in patients. When they come to get a diagnosis, they sometimes ask you were themselves like why something happened. And most of the time, we really have to say that we don't know why. I think there's even a medical term for this, which is that something it's adiabatic, which means that we have absolutely no idea what costed and I really hated it. I hated not being able to have answers for my patients. And I mean, I still don't have all the answers. But I think as I moved forward into an environmental health career, I realized that this field of environmental health had a lot of those answers. And that through my medical education, I barely heard of those. So I think that's what made me shift.Brian Bienkowski 08:18So we're going to talk more about your your research and that switch. And, you know, maybe some ideas you have for the medical field to bridge some of these gaps. But I have to ask, did your did family and friends question your decision? I mean, being a physician is a is a career that I think most of us know. I mean, we all know that career. It's familiar to us. It's a pillar in most communities. And I think researcher is a little more esoteric to a lot of folks. So I'm wondering if your family was like, What are you doing?Maria Jose Talayero Schettino 08:48Oh, my gosh, yeah, I every single person that went through medical school with me or even my family, or even friends, or even now that I meet people, when I tell them that I went through medical school and that I became a physician. Now I do environmental health, every single person has questioned that. And I feel like sometimes, when like for the Mexican perspective, a lot of people questioned this because they don't really know much about the field, and how important it is. But I don't know like having all these people question your life decision makes it like just harder to move forward and harder to realize if you're in the right path. And I think that was really hard when I first made the decision to switch. But now looking back, I don't think I would do anything differently.Brian Bienkowski 09:38And to keep on this theme of challenges. I want to reflect a bit on your move to the US. You mentioned how important Mexico City and family and gathering was to your, to your upbringing and identity. And I don't know that most folks understand the toll of immigrating even under positive circumstances like yourself. So can you talk about this experience and what people should know about the personal channel changes and sacrifices for immigrants?Maria Jose Talayero Schettino 10:02Yeah, honestly, thanks for asking this questions. I think that sometimes the challenges for like immigrating in good, some good circumstances, like I did is invisible to others. But from my experience, I really want to say that immigrating in good circumstances to the US is extremely challenging. There are so many rules and steps that you need to take that often really don't even make sense and can really make your life harder. But I do have to say that I'm really fortunate to be here. And I'm really grateful to the US for the all the all the opportunities that I've had. But moving away from family is so hard. Like you move to a country where you don't have this support system, the culture is extremely different. And you need to talk and communicate using a different language. I don't know if you've watched Modern Family. I really like that show. But there's this episode.Brian Bienkowski 10:54Modern Family? Yeah, gosh, yes. I'm a yes. I'm rewatching it right now. Yes.Maria Jose Talayero Schettino 10:59I love it. I love it. But there's this episode, where Sofia Vergara says, "do you know how smart I am in Spanish?" And it's so funny. But it's so relatable. Like, there's so many things that I want to say, but I just cannot find the words.Brian Bienkowski 11:13Well, thank you so much for sharing that. And I want to talk now about the work that you're doing as you've made the switch to research. So you're examining environmental exposures, and birth defects in Mexico. That's one of the things you're working on. So I wanted to talk about talk, you know, if you can explore this link between these exposures and birth defects, why it's concerning, and who is most impacted?Maria Jose Talayero Schettino 11:34Of course, yeah. So through my dissertation, I'm on the final stages of my doctoral program, hopefully graduating this August. But through my dissertation, I've been studying birth defects and their relationship that they have with the polluting industry in the country, in Mexico. It has been challenging to do something like this with public databases that the Mexican government has, but I found really interesting things. For example, I've seen that the reporting for genital birth defects in Mexico in the last couple of years has been steadily increasing. I mean, this could be due to so many things –like people know now how to recognize them better or many other things. But when you compare that to other countries, this seems to be happening, too. And it's making us think about the impact endocrine disrupting chemicals are having in communities around industrial areas. I think it is very concerning to see the impact that pollution has in your health even before you were born. Like I don't think people realize that we used to think in a medical field that that placenta was like this major barrier where nothing could go through it. But we've realized that that's not the case. And I really think that we don't have strict enough regulations for most chemicals. But overall, like if you asked me like, What was the most concerning thing that you saw is the lack of data that Mexico has for both health effects and polluting chemicals. I'm always amazed that countries like the US, for example, like researchers in the US say that they are so far behind, but they don't really realize if they're far behind where developing countries are.Brian Bienkowski 13:11You mentioned a term their endocrine disrupting chemicals, which I think a lot of Environmental Health News readership is aware of. But for our listening audience, can you explain what those chemicals are? And kind of the plausible ways that they could possibly be behind some of these birth defects?Maria Jose Talayero Schettino 13:26Of course, yeah, sorry, I forgot to explain that! But yeah, endocrine disrupting chemicals are generally what we say are chemicals that are capable of interfering with the way your hormones work. And your hormones are very important since the beginning of life, because hormones are also chemicals, but they mediate a lot of processes in your body. So if there's a chemical there's interrupting those pathways, then you can see problems with your development or the endocrine system diseases, for example, reproductive issues, or diabetes, or thyroid problems. So mostly, those are the things that we're concerned when we get exposed to endocrine disrupting chemicals, which are almost in everything. But one of the major things that we know, gets us exposed to endocrine disrupting chemicals, are plastics.Brian Bienkowski 14:21Soyou mentioned gaps in the research. And you noticed this pretty early on that there were some gaps in environmental health and environmental justice data in Mexico. And I know you're just one researcher, but can you talk about this dearth of research and how you're trying to tackle this?Maria Jose Talayero Schettino 14:35So I feel like environmental justice has been overlooked for centuries in both the community scale and the global scale. I really don't think high income countries realize how all their decisions impact developing countries. For example, I remember a few years ago, there was this Super Bowl held in Arizona or one of the border, one of the border states, but I think it was Arizona. And they said that they weren't going to have have a zero-waste Super Bowl because all the plastic generated was going to be recycled. But that plastic was shipped to Mexico, to northern Mexico, where plastic recycling plans are polluting the water and air of Mexican communities. So is one of the of the issues that we see in the global health realm. Like, this is not something that only happens in Mexico, but it happens everywhere. But with things like in the country level, when I first started the process to find something I wanted to do for my dissertation, I remember talking to my chair, about wanting to do something on environmental justice. So I started doing research on what was out there. And unfortunately, I wasn't able to find much. And I think this is related to what I was talking about, that we don't have a lot of data. And there's also something going on in Mexico and you know, other Latin American countries like Colombia, where it's very dangerous to be in environmentalist in those countries. Mexico is one of the deadliest country to be an environmentalist. So advocating for these things can get really challenging.Brian Bienkowski 16:03So can you talk about your efforts, in particular to advance environmental health policy in Mexico, including on lead and criminal behavior? And can you talk a little bit about your involvement with Mundo Químico, boy, I'm probably butchering these words. I'm really smart English, I swear. And what have you learned? And have you had any victories along the way in your in your efforts to advance environmental health policy down there?Maria Jose Talayero Schettino 16:28Yeah, so let me talk a little bit about what Mundo Químico is, which translates to chemical world because we live in a chemical world. So this Mundo Químico is like a collaborative of scientists and other professionals in Mexico that got together and are really trying to push programs and policies related to environmental health in the country. Honestly, I feel like I'm very lucky to be part of it. I am the youngest member. And I ended up being there because as I was finishing up my master's program, I always felt like I owed something to my country, and I needed to do something in Mexico. So I did some research and who was working on environmental health in the country. And I found this very big and famous scientist, his name is Dr. Carlos Santos Burdoa. He's US-based. He was at the George Washington University, when I first heard of that of him. So I email him. Honestly, I didn't expect a reply, because like, senior scientists are really busy. But I did get a reply. And I was really surprised. But he told me that he was building this collaborative called Mundo Químico, and he asked me if I wanted to join him. So of course, I said, Yes. So what we've been trying to do, as I was saying, is to push environmental health agenda into the policies and to do some programs to reduce environmental health exposures. And we started with lead exposure, because Mexico has a really big problem with lead. I think we've done different things that I don't think I have enough time to talk about during our podcast. But what I have learned, and I think I have learned a lot of things, but one of the most important ones, is that it is so hard to communicate to the public and with policymakers. And I really did not expect that when I started my career in environmental health. And I think that's how I ended up studying lead exposure and criminal behavior. Because often when you want policymakers to listen to what you have to say, you have to talk to them in their terms, and talk to them in topics that that you feel that they will prioritize. So we know crime is a big thing in Mexico. So what we did is where we viewed all the available evidence to see how lead exposure was related to criminal behavior, we found that there's a link. But we still need research on this. And we need research to understand what the relationship means in the Mexican context. But yeah, I feel like that's how it started because we need to learn to communicate with policymakers. And I really don't want to stop talking about this question without mentioning some of the wins that we had, because I feel like in environmental health, we will always hear a lot about our fatals and not our wins. So we have had some wins, we have been able to produce some programs on lead exposure. And one of them is we were able to partner with WONART, which is an Arts Fund that the government of Mexico has and through their through them, we've been able to push this program to train pottery workers to produce lathe, Clay ceramics, which are a major traditional thing in Mexico and they usually have led in it. But we're pushing this program to produce lead-free clay ceramics and to certify that they're lead free. And even though we still have a lot of work to do on that issue, the start of the program to me is just a great win.Brian Bienkowski 19:54You mentioned two things there that I have a follow up on and you started to get to it a little bit at the end is is you meantioned that lead exposure is a big issue in Mexico. And I'm wondering if you can just kind of give a brief overview of the ceramics and potentially other sources of lead in the environment there. And then second, if you can kind of walk us through why there's this possible link to crime, what does lead do to people that could make them more susceptible to committing crime?Maria Jose Talayero Schettino 20:20Of course, yeah. So I'll start with at glaced clay ceramics. So in Mexico, we use traditional pottery for cooking, storing, or even serving food. And one of this traditional pottery is called glaced clay ceramics and the glaze that the ceramics have, it has lead in it. And because it's not produced in ovens, that can reach high enough temperatures, in like close ovens, because it's a very artisanal process, the lead stays there, and it leeches into food. And he usually leeches when you like cook, or store food that's very acidic. And Mexican cuisine is really acidic. So it leaves us a lot of lead. And we have a major problem of lead exposure. Because of that, that's actually the main source of lead exposure in the country, because most of the people in Mexico use it. Like if you go down there, you'll see it in restaurants, you'll see your honestly see it everywhere. And the latest numbers show that children from one to four ages in Mexico, 17% of all children from one to four years of age in Mexico have lead poisoning. So it's a really public health issue, we don't have data to see if older kids have lead, we don't have data on adults. But it's a really big concern, because lead is very toxic, like the WHO says that there is no safe level of exposure to lead because of how toxic it is. And he causes a variety of things. It can increase cardiovascular disease, it can damage the kidneys. But one of the ones, one of the things that we have studied the most is how it damages the nervous system and the brain. And this goes back to the question that you asked about criminal behavior. So we've seen that lead damages the prefrontal cortex of the brain, which is in charge of, of behavior, and, yeah, to put it in, like, easier terms, yeah, it's in charge of behavior and how you react to things. So when it damages the neurons there, it can cause antisocial behavior, and it can cause aggressiveness, and it can cause violent behaviors. So that's how we've seen it has associated with criminal behavior. So in addition to that communication work directly with policymakers and residents, I know you're also active on social media. And I'm wondering how you've leveraged those platforms to try to get the word out on some of these environmental ills. Oh, my gosh, being on social media is so hard. I don't know if you've tried it. But seriously, it takes a lot of effort to create content on social media. But yeah, so I ended up in social media, because going back to this environmental justice issues, Spanish speaking countries, and communities really don't have as much information as English speakers do. And that's something I really noticed while I was scrolling down on every social media platform, so I saw hundreds of videos on how to reduce environmental exposures, but almost none, were in Spanish. So I decided to venture into social media. And honestly, I don't have that many followers, my platform is growing. But one of the things that I've noticed is that many health professionals are starting to follow me because they're interested. And they want to learn more, because some of their patients are asking about these topics. So I feel like it's a great way to do outreach and communication, things when you're in the environmental health field.Brian Bienkowski 24:06I have not tried it. Of course, I had I had social media accounts. It's been more than a decade. I think since I've had one, I don't even have LinkedIn anymore. I am really happy that people like you are on them, because I think it is a counterbalance to the reason that I got off, which is a lot of kind of miss information and hatred. But it is really heartening for me to see folks like yourself and scientists in general and health professionals are able to take their message directly to people as opposed to kind of being mediated through, you know, newspapers or whatever happened back in the day. So I think that's a good thing. And we have noticed though, as a newsroom, a lack of Spanish language environmental content and information and we are trying to trying to combat that with some eh en español coverage. So We have noticed the same thing as you. And there is a real language justice issue in the United States when it comes to environmental information. So I hope people will follow you. We will add a link in this podcast article so people can follow you if you want. Having spent some time now in the environmental health research field, and we were talking earlier about how you started as a physician, how do you think the medical field could better incorporate environmental health information for patients and prepare those physicians?Maria Jose Talayero Schettino 25:28I mean, I honestly wish health care workers have better training in environmental health. From my experience, which is going through medical school in Mexico, I really can't speak for other countries. I barely heard about environmental exposures as causes of disease, when I was in medical school, maybe I heard about asbestos or silicosis or occupational exposures, but non an environmental exposures like a social determinants of health, which they are. So I'm currently working actually on a project with some peers on how there is a huge gap in medical and other other healthcare professions school curriculum when it comes to environmental health in Latin America. And it is a sad reality that we barely see courses on environmental health in these curriculums. But I can tell you that I like I can see myself advocating about this for a really long time. And I think we need to get to a point where every single doctor, every single dentist, every single nutritionist, every single nurse knows that this exists, and that we need to know about it and talk to our patients about it.Brian Bienkowski 26:41This is purely anecdotal. But I do feel like I'm seeing more on the climate side of things where physicians are being more active and perhaps more trained in climate change and extreme heat, but less so on –surprisingly– less so on things like chemical exposure, and the things that you've been talking about endocrine disrupting chemicals. So hopefully, hopefully, that changes because I think that would be a real public health win. So, Maria, this has been so much fun hearing about you and your work. And I have to ask you, before we get to some of the fun questions, I have a couple more questions. And one is do you plan on going back to Mexico? Would you want to work there? Or do you think you'll stay in the United States? What do you want to do with this environmental health research training?Maria Jose Talayero Schettino 27:25Oh, my gosh, you're putting me on the spot.Brian Bienkowski 27:28I mean, you can have a no comment.Maria Jose Talayero Schettino 27:30I know my family's gonna want me to give an answer that maybe it's not the one that they like. But I do feel that the work that I'm doing for Mexico in the United States, is far like, I feel like I have way more opportunities to do something for my country from the United States, than the ones that I see that are my country. And it's a really sad reality, because I would give the world to just go back to my family and my nephews. But if I really want to see a change, I really feel like I have to stay in the United States for at least a couple of years. To improve, like my research techniques to get a better sense of what's out there and what I can do for Mexico. I mean, in the future. I don't know how long from from now, I do see myself going back to Mexico at some point. But right now, I don't think it is an option. And it is a sad reality, not only for me, but for other immigrants that are doing science in the United States, because our countries lack opportunities.Brian Bienkowski 28:39And Maria, before we get to the fun stuff, what are you optimistic about?Maria Jose Talayero Schettino 28:44Oh, that's a really important question! I feel like we don't hear about optimism sometimes in the environmental field, like there are so it's filled with bad news sometimes. But I feel like I'm optimistic about hearing more people are learning about environmental exposure. So how they can affect their health, because honestly, sometimes social movements can move policies faster. So we really need that. I'm optimistic about how younger generations are thinking more about the environment now. And they're joining this fight. There are so many things I'm optimistic about. And I'm glad you brought this up. Because again, I don't think that this field is full of good news. So we need to, to have these victories and these things that we're optimistic about really present in our day to day because he can get overwhelming at times.Brian Bienkowski 29:37I think the hard thing in my profession and maybe this is true in science in science communication as well, is whenever we try to talk about good news, it often feels like we're perhaps greenwashing or perhaps we're overlooking, you know, renewable energy is a great example. You know, solar energy and wind energy are less polluting, however now we have to go get those chemicals to make those panels in the ground and community. You know, so there's always there's other problems and we don't want to overlook those. But I totally agree with you that we need to be better as a, as a country in general about celebrating environmental wins, so people just don't get so down about it.Maria Jose Talayero Schettino 30:17Yeah, cuz I mean, when I talk to people about toxic exposures, I usually get the same reaction, like, everything's toxic, I'm gonna die from something. So I might as well just stop thinking about this. And I don't think that's a great approach. So, I mean, that should go back to our communication efforts, like, what are we saying, what are we doing? And how can we make this better? So our message gets out there, and it's not as overwhelming as it is currently.Brian Bienkowski 30:43100% totally agree with you. Well, Maria, thank you so much for your time. I'm just so I'm so happy to have met you and have you in this program. I'm just really excited about the work you're doing. So before I get you out of here, I have a few rapid fire questions where you can just answer with a one word or a phrase, if I have a whole day off, I am likely.Maria Jose Talayero Schettino 31:05Oh my gosh, I'm probably hitting the craft store to find a new craft to doBrian Bienkowski 31:09What what type of crafting do you like do?Maria Jose Talayero Schettino 31:12anything, like anything like it, maybe it's knitting, maybe it's stitching, maybe it's painting, whatever, like, whatever is new, I'm doing it.Brian Bienkowski 31:22So my wife and I, we live in the Upper Peninsula. And so we have very long winters. And I find myself this time of year. And I hesitate to even say this pining for winter, because it is such a great time to be quiet. And I play I'm playing music and my wife does be beadwork and stuff like that. Or we do some paintings together. And it's all crafty, and it's cozy and quiet. And then in the summer, I find that I really miss those. I really missed those times. So I need to find a way to do more crafty things, when it's nice outside. Yeah,Maria Jose Talayero Schettino 31:54I can relate to that. 100% I feel like it's a great therapy to do craftBrian Bienkowski 31:58100%. Well, I just had a guest on who was the guest, I'm forgetting now. But I had a guest on we were talking crafts not too long ago, I'll have to dig that out. Because I think it's for folks like yourself who are really busy doing this kind of work. It's good to have that other side of your creative brain get used every now and then. So the best gift I've ever received isMaria Jose Talayero Schettino 32:22I'm gonna see my family.Brian Bienkowski 32:24And if I could immediately gain one talent or ability it would beMaria Jose Talayero Schettino 32:31I know, to be able to get grants for research without being rejected.Brian Bienkowski 32:37Not flight or invisibility, just just grants! this one good for research. keeping it simple. I like that. And you do not have to. You can talk more than one word or a phrase here. What is the last book you read for fun?Maria Jose Talayero Schettino 32:53Oh, this is a good one. So lately because I've been working on my dissertation. I feel like I've been reading a lot of science stuff. But I feel like the last book that I read it was, I feel it was last year. And it's a book by a Mexican Indigenous woman, well, Ilfrosina Cruz who is now a representative in the Mexican government. And it's a great book. I'm not gonna spoil it for everyone. But she talks about her life as an Indigenous girl and how she wanted something different. And she wanted to create opportunities. And she moved on to be a representative and changing the laws in Mexico. So it's a really inspiring book, and I highly recommend it, it is called "Los Sueños de la niña de la montaña," which translates to "The Dreams from the girl up the mountain. I don't know if it's available in English yet, but I know it's in Spanish and I really highly recommended.Brian Bienkowski 33:46Excellent. Well, Maria, thank you so much for your time today. Thank you for being part of this program, and we'll have you back soon.Maria Jose Talayero Schettino 33:51Thank you. Thank you so much for having me.

Transcript


Maria Jose Talayero Schettino 00:00

I don't I really don't think high income countries realize how all their decisions impact developing countries.

Brian Bienkowski 00:11

Hello and welcome back to the Agents of Change in Environmental Justice podcast, a partnership between Environmental Health News and Columbia University's Mailman School of Public Health. I'm your host Brian Bienkowski, editor of Agents of Change, and senior editor at Environmental Health News. Folks, we are so grateful for your support. We've been at this a few years now and we would love to continue to grow. Please share this podcast with your family and friends, colleagues, and subscribe to us on Spotify or iTunes and please leave us a review. Today's guest is Dr. Maria Jose Talayero Schettino, a current fellow and a doctorate pH candidate in the Department of Environmental and Occupational Health at the George Washington University. Maria talks about switching careers from a physician to an environmental health researcher, using her research to advocate for environmental justice in her native Mexico and how the medical field can better prepare doctors to understand the effects of environmental pollutants on our health. Enjoy. All right, I am now joined by Dr. Maria,Jose Talayero Schettino. Maria, how are you doing today?

Maria Jose Talayero Schettino 01:14

I'm doing great. Thanks for having me here. Brian, how are you?

Brian Bienkowski 01:18

I am doing wonderful. And I'm really excited to hear about all the work that you're doing. But I want to start at the very beginning. Tell me about growing up in Mexico City.

Maria Jose Talayero Schettino 01:29

Oh, yeah, I honestly have very good memories about growing up in Mexico City. But I'm not sure how familiar you are with Mexican culture or if you've ever traveled there, but

Brian Bienkowski 01:41

almost zero

Maria Jose Talayero Schettino 01:42

Mexicans really highly, highly value things like hospitality, generosity, respect for elders, solidarity. And it might sound really funny, but we highly value social connections and gatherings. I mean, it's weird to say that we really value parties, but we do. And that's why our food and culture is so important. So I feel like growing up in Mexico City was just like that: full of culture, tradition, family gatherings. And I feel like I'm very lucky to be able to call myself Mexican.

Brian Bienkowski 02:12

Is there a certain food or or holiday or gathering? Are there certain ones that kind of stick out in your mind as being particularly poignant?

Maria Jose Talayero Schettino 02:22

I mean, yes, I think so. Particularly, Independence Day. I have very good memories about going to watch the fireworks. Independence Days in September. Most people in America think it's Cinco de Mayo. But that's not it. It's in September. But other holidays that really stick up for me are the other mortos which is in November, and also Posadas, which are held during like, December. So Christmas is very important to us too.

Brian Bienkowski 02:54

And the only thing I really know about Mexico City, and pardon my American ignorance, is it's it's a massive city, right? I mean, were you in kind of a dense urban area?

Maria Jose Talayero Schettino 03:04

I mean, yeah, it's a huge, huge city. And I feel like there's a lot of people living around Mexico City, I did feel like I lived with my family in one of like, more suburban area, not closer to like, the historical center or anything. But we travel a lot by car. I mean, we have a huge air pollution problem because of that. But I feel like yeah, it's a huge city, and everyone's all around it in. I mean, it's very, very well connected when it comes to streets, we have a lot of traffic, but that's how people go around Mexico City by staying in traffic for really long periods of time.

Brian Bienkowski 03:48

So how and when did you become interested in health and the environment?

Maria Jose Talayero Schettino 03:53

I mean, this is a great question. And every time I get it, I wish I had that story, "like when I was younger, I used to tell my parents that I wanted to be a doctor since I was a little girl." Unfortunately, that was not me. I wanted to be a singer. I wanted to be an artist. I wanted to be a painter. So that was not me. So I think I ended up in like healthcare and the environment because I really loved science. And don't get me wrong, I really hated physics and math. So because they hated it, I feel like that drew me into chemistry and biology. And I I think I ended up in medical school because of that, because my love for science and honestly, I never knew I was gonna end up doing research and doing a lot of statistics. Even after I ran away from math.

Brian Bienkowski 04:42

The only class I ever got to see in growing up was chemistry that that that for some reason that subject gave me such fits. And I don't know if it was my teacher, or what but it really bothered me.

Maria Jose Talayero Schettino 04:54

I mean, yeah, it's a really, really hard, hard subject! and I I feel you I feel like I just don't know, I don't know what it was. But chemistry and biology always caught my eye.

Brian Bienkowski 05:05

eye. And the weird thing is now I, you know, I've spent most of my career writing about chemicals in the environment. So it's, it's strange, I hope I'm not just writing a bunch of incorrect things.

Maria Jose Talayero Schettino 05:17

I guess I guess you've made peace with it. And now you love it.

Brian Bienkowski 05:21

That's right. So before we get into your your career has been fascinating because you, you started off in healthcare as a physician, and I want to talk about your journey. But first, what is a moment or event that has helped shape your identity?

Maria Jose Talayero Schettino 05:35

Wow, that's a really hard question. I think there are a couple of things that I want to mention that really shaped my identity as I was growing up. And I feel like the first one was really practicing medicine in public hospitals, that really showed me that life is not fair. And that made me want to work on that. And I think the other thing I want to mention that really shaped my identity is immigrating to the United States, even though I emigrated when I was, I think, 26 years old. Even though I'm like a short four-hour flight away from home, I think immigrating made me realize about all the things that I took for granted, and now I really highly value.

Brian Bienkowski 06:16

Luckily, we're going to talk about both of those things. Because I think that's, it's a really important part of your journey. And starting with this idea of you became a physician in practice in rural communities around Mexico City. So can you tell me about this work, what you learned from this time with patients and why ultimately, you decided to switch careers?

Maria Jose Talayero Schettino 06:34

Of course. So I guess, practicing medicine in rural communities, and even public hospitals, or public health care centers in Mexico, it really does feel like an art. Because you need to learn how to treat disease differently. Sometimes the medicines that you learn on a book that were the best for a specific disease are not available. So you have to work around it. And the same comes for like diagnostic diagnostic tools, you don't have fancy equipment, or even sometimes you don't even have basic equipment to make a diagnosis. So you have to really focus on talking to the patient. And that's the only thing that you often have, and you have to learn how to practice medicine with that, which is the only thing that you have. And I think when it comes to the change that I made from like, a very clinical-practice-based career into like an research and an environmental one is that one of the things that frustrated me that most while I was practicing medicine is that there were and there are still a lot of things that we do not have answers for in patients. When they come to get a diagnosis, they sometimes ask you were themselves like why something happened. And most of the time, we really have to say that we don't know why. I think there's even a medical term for this, which is that something it's adiabatic, which means that we have absolutely no idea what costed and I really hated it. I hated not being able to have answers for my patients. And I mean, I still don't have all the answers. But I think as I moved forward into an environmental health career, I realized that this field of environmental health had a lot of those answers. And that through my medical education, I barely heard of those. So I think that's what made me shift.

Brian Bienkowski 08:18

So we're going to talk more about your your research and that switch. And, you know, maybe some ideas you have for the medical field to bridge some of these gaps. But I have to ask, did your did family and friends question your decision? I mean, being a physician is a is a career that I think most of us know. I mean, we all know that career. It's familiar to us. It's a pillar in most communities. And I think researcher is a little more esoteric to a lot of folks. So I'm wondering if your family was like, What are you doing?

Maria Jose Talayero Schettino 08:48

Oh, my gosh, yeah, I every single person that went through medical school with me or even my family, or even friends, or even now that I meet people, when I tell them that I went through medical school and that I became a physician. Now I do environmental health, every single person has questioned that. And I feel like sometimes, when like for the Mexican perspective, a lot of people questioned this because they don't really know much about the field, and how important it is. But I don't know like having all these people question your life decision makes it like just harder to move forward and harder to realize if you're in the right path. And I think that was really hard when I first made the decision to switch. But now looking back, I don't think I would do anything differently.

Brian Bienkowski 09:38

And to keep on this theme of challenges. I want to reflect a bit on your move to the US. You mentioned how important Mexico City and family and gathering was to your, to your upbringing and identity. And I don't know that most folks understand the toll of immigrating even under positive circumstances like yourself. So can you talk about this experience and what people should know about the personal channel changes and sacrifices for immigrants?

Maria Jose Talayero Schettino 10:02

Yeah, honestly, thanks for asking this questions. I think that sometimes the challenges for like immigrating in good, some good circumstances, like I did is invisible to others. But from my experience, I really want to say that immigrating in good circumstances to the US is extremely challenging. There are so many rules and steps that you need to take that often really don't even make sense and can really make your life harder. But I do have to say that I'm really fortunate to be here. And I'm really grateful to the US for the all the all the opportunities that I've had. But moving away from family is so hard. Like you move to a country where you don't have this support system, the culture is extremely different. And you need to talk and communicate using a different language. I don't know if you've watched Modern Family. I really like that show. But there's this episode.

Brian Bienkowski 10:54

Modern Family? Yeah, gosh, yes. I'm a yes. I'm rewatching it right now. Yes.

Maria Jose Talayero Schettino 10:59

I love it. I love it. But there's this episode, where Sofia Vergara says, "do you know how smart I am in Spanish?" And it's so funny. But it's so relatable. Like, there's so many things that I want to say, but I just cannot find the words.

Brian Bienkowski 11:13

Well, thank you so much for sharing that. And I want to talk now about the work that you're doing as you've made the switch to research. So you're examining environmental exposures, and birth defects in Mexico. That's one of the things you're working on. So I wanted to talk about talk, you know, if you can explore this link between these exposures and birth defects, why it's concerning, and who is most impacted?

Maria Jose Talayero Schettino 11:34

Of course, yeah. So through my dissertation, I'm on the final stages of my doctoral program, hopefully graduating this August. But through my dissertation, I've been studying birth defects and their relationship that they have with the polluting industry in the country, in Mexico. It has been challenging to do something like this with public databases that the Mexican government has, but I found really interesting things. For example, I've seen that the reporting for genital birth defects in Mexico in the last couple of years has been steadily increasing. I mean, this could be due to so many things –like people know now how to recognize them better or many other things. But when you compare that to other countries, this seems to be happening, too. And it's making us think about the impact endocrine disrupting chemicals are having in communities around industrial areas. I think it is very concerning to see the impact that pollution has in your health even before you were born. Like I don't think people realize that we used to think in a medical field that that placenta was like this major barrier where nothing could go through it. But we've realized that that's not the case. And I really think that we don't have strict enough regulations for most chemicals. But overall, like if you asked me like, What was the most concerning thing that you saw is the lack of data that Mexico has for both health effects and polluting chemicals. I'm always amazed that countries like the US, for example, like researchers in the US say that they are so far behind, but they don't really realize if they're far behind where developing countries are.

Brian Bienkowski 13:11

You mentioned a term their endocrine disrupting chemicals, which I think a lot of Environmental Health News readership is aware of. But for our listening audience, can you explain what those chemicals are? And kind of the plausible ways that they could possibly be behind some of these birth defects?

Maria Jose Talayero Schettino 13:26

Of course, yeah, sorry, I forgot to explain that! But yeah, endocrine disrupting chemicals are generally what we say are chemicals that are capable of interfering with the way your hormones work. And your hormones are very important since the beginning of life, because hormones are also chemicals, but they mediate a lot of processes in your body. So if there's a chemical there's interrupting those pathways, then you can see problems with your development or the endocrine system diseases, for example, reproductive issues, or diabetes, or thyroid problems. So mostly, those are the things that we're concerned when we get exposed to endocrine disrupting chemicals, which are almost in everything. But one of the major things that we know, gets us exposed to endocrine disrupting chemicals, are plastics.

Brian Bienkowski 14:21

Soyou mentioned gaps in the research. And you noticed this pretty early on that there were some gaps in environmental health and environmental justice data in Mexico. And I know you're just one researcher, but can you talk about this dearth of research and how you're trying to tackle this?

Maria Jose Talayero Schettino 14:35

So I feel like environmental justice has been overlooked for centuries in both the community scale and the global scale. I really don't think high income countries realize how all their decisions impact developing countries. For example, I remember a few years ago, there was this Super Bowl held in Arizona or one of the border, one of the border states, but I think it was Arizona. And they said that they weren't going to have have a zero-waste Super Bowl because all the plastic generated was going to be recycled. But that plastic was shipped to Mexico, to northern Mexico, where plastic recycling plans are polluting the water and air of Mexican communities. So is one of the of the issues that we see in the global health realm. Like, this is not something that only happens in Mexico, but it happens everywhere. But with things like in the country level, when I first started the process to find something I wanted to do for my dissertation, I remember talking to my chair, about wanting to do something on environmental justice. So I started doing research on what was out there. And unfortunately, I wasn't able to find much. And I think this is related to what I was talking about, that we don't have a lot of data. And there's also something going on in Mexico and you know, other Latin American countries like Colombia, where it's very dangerous to be in environmentalist in those countries. Mexico is one of the deadliest country to be an environmentalist. So advocating for these things can get really challenging.

Brian Bienkowski 16:03

So can you talk about your efforts, in particular to advance environmental health policy in Mexico, including on lead and criminal behavior? And can you talk a little bit about your involvement with Mundo Químico, boy, I'm probably butchering these words. I'm really smart English, I swear. And what have you learned? And have you had any victories along the way in your in your efforts to advance environmental health policy down there?

Maria Jose Talayero Schettino 16:28

Yeah, so let me talk a little bit about what Mundo Químico is, which translates to chemical world because we live in a chemical world. So this Mundo Químico is like a collaborative of scientists and other professionals in Mexico that got together and are really trying to push programs and policies related to environmental health in the country. Honestly, I feel like I'm very lucky to be part of it. I am the youngest member. And I ended up being there because as I was finishing up my master's program, I always felt like I owed something to my country, and I needed to do something in Mexico. So I did some research and who was working on environmental health in the country. And I found this very big and famous scientist, his name is Dr. Carlos Santos Burdoa. He's US-based. He was at the George Washington University, when I first heard of that of him. So I email him. Honestly, I didn't expect a reply, because like, senior scientists are really busy. But I did get a reply. And I was really surprised. But he told me that he was building this collaborative called Mundo Químico, and he asked me if I wanted to join him. So of course, I said, Yes. So what we've been trying to do, as I was saying, is to push environmental health agenda into the policies and to do some programs to reduce environmental health exposures. And we started with lead exposure, because Mexico has a really big problem with lead. I think we've done different things that I don't think I have enough time to talk about during our podcast. But what I have learned, and I think I have learned a lot of things, but one of the most important ones, is that it is so hard to communicate to the public and with policymakers. And I really did not expect that when I started my career in environmental health. And I think that's how I ended up studying lead exposure and criminal behavior. Because often when you want policymakers to listen to what you have to say, you have to talk to them in their terms, and talk to them in topics that that you feel that they will prioritize. So we know crime is a big thing in Mexico. So what we did is where we viewed all the available evidence to see how lead exposure was related to criminal behavior, we found that there's a link. But we still need research on this. And we need research to understand what the relationship means in the Mexican context. But yeah, I feel like that's how it started because we need to learn to communicate with policymakers. And I really don't want to stop talking about this question without mentioning some of the wins that we had, because I feel like in environmental health, we will always hear a lot about our fatals and not our wins. So we have had some wins, we have been able to produce some programs on lead exposure. And one of them is we were able to partner with WONART, which is an Arts Fund that the government of Mexico has and through their through them, we've been able to push this program to train pottery workers to produce lathe, Clay ceramics, which are a major traditional thing in Mexico and they usually have led in it. But we're pushing this program to produce lead-free clay ceramics and to certify that they're lead free. And even though we still have a lot of work to do on that issue, the start of the program to me is just a great win.

Brian Bienkowski 19:54

You mentioned two things there that I have a follow up on and you started to get to it a little bit at the end is is you meantioned that lead exposure is a big issue in Mexico. And I'm wondering if you can just kind of give a brief overview of the ceramics and potentially other sources of lead in the environment there. And then second, if you can kind of walk us through why there's this possible link to crime, what does lead do to people that could make them more susceptible to committing crime?

Maria Jose Talayero Schettino 20:20

Of course, yeah. So I'll start with at glaced clay ceramics. So in Mexico, we use traditional pottery for cooking, storing, or even serving food. And one of this traditional pottery is called glaced clay ceramics and the glaze that the ceramics have, it has lead in it. And because it's not produced in ovens, that can reach high enough temperatures, in like close ovens, because it's a very artisanal process, the lead stays there, and it leeches into food. And he usually leeches when you like cook, or store food that's very acidic. And Mexican cuisine is really acidic. So it leaves us a lot of lead. And we have a major problem of lead exposure. Because of that, that's actually the main source of lead exposure in the country, because most of the people in Mexico use it. Like if you go down there, you'll see it in restaurants, you'll see your honestly see it everywhere. And the latest numbers show that children from one to four ages in Mexico, 17% of all children from one to four years of age in Mexico have lead poisoning. So it's a really public health issue, we don't have data to see if older kids have lead, we don't have data on adults. But it's a really big concern, because lead is very toxic, like the WHO says that there is no safe level of exposure to lead because of how toxic it is. And he causes a variety of things. It can increase cardiovascular disease, it can damage the kidneys. But one of the ones, one of the things that we have studied the most is how it damages the nervous system and the brain. And this goes back to the question that you asked about criminal behavior. So we've seen that lead damages the prefrontal cortex of the brain, which is in charge of, of behavior, and, yeah, to put it in, like, easier terms, yeah, it's in charge of behavior and how you react to things. So when it damages the neurons there, it can cause antisocial behavior, and it can cause aggressiveness, and it can cause violent behaviors. So that's how we've seen it has associated with criminal behavior. So in addition to that communication work directly with policymakers and residents, I know you're also active on social media. And I'm wondering how you've leveraged those platforms to try to get the word out on some of these environmental ills. Oh, my gosh, being on social media is so hard. I don't know if you've tried it. But seriously, it takes a lot of effort to create content on social media. But yeah, so I ended up in social media, because going back to this environmental justice issues, Spanish speaking countries, and communities really don't have as much information as English speakers do. And that's something I really noticed while I was scrolling down on every social media platform, so I saw hundreds of videos on how to reduce environmental exposures, but almost none, were in Spanish. So I decided to venture into social media. And honestly, I don't have that many followers, my platform is growing. But one of the things that I've noticed is that many health professionals are starting to follow me because they're interested. And they want to learn more, because some of their patients are asking about these topics. So I feel like it's a great way to do outreach and communication, things when you're in the environmental health field.

Brian Bienkowski 24:06

I have not tried it. Of course, I had I had social media accounts. It's been more than a decade. I think since I've had one, I don't even have LinkedIn anymore. I am really happy that people like you are on them, because I think it is a counterbalance to the reason that I got off, which is a lot of kind of miss information and hatred. But it is really heartening for me to see folks like yourself and scientists in general and health professionals are able to take their message directly to people as opposed to kind of being mediated through, you know, newspapers or whatever happened back in the day. So I think that's a good thing. And we have noticed though, as a newsroom, a lack of Spanish language environmental content and information and we are trying to trying to combat that with some eh en español coverage. So We have noticed the same thing as you. And there is a real language justice issue in the United States when it comes to environmental information. So I hope people will follow you. We will add a link in this podcast article so people can follow you if you want. Having spent some time now in the environmental health research field, and we were talking earlier about how you started as a physician, how do you think the medical field could better incorporate environmental health information for patients and prepare those physicians?

Maria Jose Talayero Schettino 25:28

I mean, I honestly wish health care workers have better training in environmental health. From my experience, which is going through medical school in Mexico, I really can't speak for other countries. I barely heard about environmental exposures as causes of disease, when I was in medical school, maybe I heard about asbestos or silicosis or occupational exposures, but non an environmental exposures like a social determinants of health, which they are. So I'm currently working actually on a project with some peers on how there is a huge gap in medical and other other healthcare professions school curriculum when it comes to environmental health in Latin America. And it is a sad reality that we barely see courses on environmental health in these curriculums. But I can tell you that I like I can see myself advocating about this for a really long time. And I think we need to get to a point where every single doctor, every single dentist, every single nutritionist, every single nurse knows that this exists, and that we need to know about it and talk to our patients about it.

Brian Bienkowski 26:41

This is purely anecdotal. But I do feel like I'm seeing more on the climate side of things where physicians are being more active and perhaps more trained in climate change and extreme heat, but less so on –surprisingly– less so on things like chemical exposure, and the things that you've been talking about endocrine disrupting chemicals. So hopefully, hopefully, that changes because I think that would be a real public health win. So, Maria, this has been so much fun hearing about you and your work. And I have to ask you, before we get to some of the fun questions, I have a couple more questions. And one is do you plan on going back to Mexico? Would you want to work there? Or do you think you'll stay in the United States? What do you want to do with this environmental health research training?

Maria Jose Talayero Schettino 27:25

Oh, my gosh, you're putting me on the spot.

Brian Bienkowski 27:28

I mean, you can have a no comment.

Maria Jose Talayero Schettino 27:30

I know my family's gonna want me to give an answer that maybe it's not the one that they like. But I do feel that the work that I'm doing for Mexico in the United States, is far like, I feel like I have way more opportunities to do something for my country from the United States, than the ones that I see that are my country. And it's a really sad reality, because I would give the world to just go back to my family and my nephews. But if I really want to see a change, I really feel like I have to stay in the United States for at least a couple of years. To improve, like my research techniques to get a better sense of what's out there and what I can do for Mexico. I mean, in the future. I don't know how long from from now, I do see myself going back to Mexico at some point. But right now, I don't think it is an option. And it is a sad reality, not only for me, but for other immigrants that are doing science in the United States, because our countries lack opportunities.

Brian Bienkowski 28:39

And Maria, before we get to the fun stuff, what are you optimistic about?

Maria Jose Talayero Schettino 28:44

Oh, that's a really important question! I feel like we don't hear about optimism sometimes in the environmental field, like there are so it's filled with bad news sometimes. But I feel like I'm optimistic about hearing more people are learning about environmental exposure. So how they can affect their health, because honestly, sometimes social movements can move policies faster. So we really need that. I'm optimistic about how younger generations are thinking more about the environment now. And they're joining this fight. There are so many things I'm optimistic about. And I'm glad you brought this up. Because again, I don't think that this field is full of good news. So we need to, to have these victories and these things that we're optimistic about really present in our day to day because he can get overwhelming at times.

Brian Bienkowski 29:37

I think the hard thing in my profession and maybe this is true in science in science communication as well, is whenever we try to talk about good news, it often feels like we're perhaps greenwashing or perhaps we're overlooking, you know, renewable energy is a great example. You know, solar energy and wind energy are less polluting, however now we have to go get those chemicals to make those panels in the ground and community. You know, so there's always there's other problems and we don't want to overlook those. But I totally agree with you that we need to be better as a, as a country in general about celebrating environmental wins, so people just don't get so down about it.

Maria Jose Talayero Schettino 30:17

Yeah, cuz I mean, when I talk to people about toxic exposures, I usually get the same reaction, like, everything's toxic, I'm gonna die from something. So I might as well just stop thinking about this. And I don't think that's a great approach. So, I mean, that should go back to our communication efforts, like, what are we saying, what are we doing? And how can we make this better? So our message gets out there, and it's not as overwhelming as it is currently.

Brian Bienkowski 30:43

100% totally agree with you. Well, Maria, thank you so much for your time. I'm just so I'm so happy to have met you and have you in this program. I'm just really excited about the work you're doing. So before I get you out of here, I have a few rapid fire questions where you can just answer with a one word or a phrase, if I have a whole day off, I am likely.

Maria Jose Talayero Schettino 31:05

Oh my gosh, I'm probably hitting the craft store to find a new craft to do

Brian Bienkowski 31:09

What what type of crafting do you like do?

Maria Jose Talayero Schettino 31:12

anything, like anything like it, maybe it's knitting, maybe it's stitching, maybe it's painting, whatever, like, whatever is new, I'm doing it.

Brian Bienkowski 31:22

So my wife and I, we live in the Upper Peninsula. And so we have very long winters. And I find myself this time of year. And I hesitate to even say this pining for winter, because it is such a great time to be quiet. And I play I'm playing music and my wife does be beadwork and stuff like that. Or we do some paintings together. And it's all crafty, and it's cozy and quiet. And then in the summer, I find that I really miss those. I really missed those times. So I need to find a way to do more crafty things, when it's nice outside. Yeah,

Maria Jose Talayero Schettino 31:54

I can relate to that. 100% I feel like it's a great therapy to do craft

Brian Bienkowski 31:58

100%. Well, I just had a guest on who was the guest, I'm forgetting now. But I had a guest on we were talking crafts not too long ago, I'll have to dig that out. Because I think it's for folks like yourself who are really busy doing this kind of work. It's good to have that other side of your creative brain get used every now and then. So the best gift I've ever received is

Maria Jose Talayero Schettino 32:22

I'm gonna see my family.

Brian Bienkowski 32:24

And if I could immediately gain one talent or ability it would be

Maria Jose Talayero Schettino 32:31

I know, to be able to get grants for research without being rejected.

Brian Bienkowski 32:37

Not flight or invisibility, just just grants! this one good for research. keeping it simple. I like that. And you do not have to. You can talk more than one word or a phrase here. What is the last book you read for fun?

Maria Jose Talayero Schettino 32:53

Oh, this is a good one. So lately because I've been working on my dissertation. I feel like I've been reading a lot of science stuff. But I feel like the last book that I read it was, I feel it was last year. And it's a book by a Mexican Indigenous woman, well, Ilfrosina Cruz who is now a representative in the Mexican government. And it's a great book. I'm not gonna spoil it for everyone. But she talks about her life as an Indigenous girl and how she wanted something different. And she wanted to create opportunities. And she moved on to be a representative and changing the laws in Mexico. So it's a really inspiring book, and I highly recommend it, it is called "Los Sueños de la niña de la montaña," which translates to "The Dreams from the girl up the mountain. I don't know if it's available in English yet, but I know it's in Spanish and I really highly recommended.

Brian Bienkowski 33:46

Excellent. Well, Maria, thank you so much for your time today. Thank you for being part of this program, and we'll have you back soon.

Maria Jose Talayero Schettino 33:51

Thank you. Thank you so much for having me. It was a great talk.

California regulators approve rules to curb methane leaks and prevent fires at landfills

California air regulators adopted new rules designed to reduce methane leaks and better respond to disastrous underground fires at landfills statewide.

In one of the most important state environmental decisions this year, California air regulators adopted new rules designed to reduce methane leaks and better respond to disastrous underground fires at landfills statewide. California Air Resources Board members voted 12-0 on Thursday to approve a batch of new regulations for the state’s nearly 200 large landfills, designed to minimize the release of methane, a powerful greenhouse gas produced by decomposing organic waste. Landfills are California’s second-largest source of methane emissions, following only the state’s large dairy cow and livestock herds.The new requirements will force landfill operators to install additional pollution controls; more comprehensively investigate methane leaks on parts of landfills that are inaccessible with on-the-ground monitoring using new technology like drones and satellites; and fix equipment breakdowns much faster. Landfill operators also will be required to repair leaks identified through California’s new satellite-detection program. The regulation is expected to prevent the release of 17,000 metric tons of methane annually — an amount capable of warming the atmosphere as much as 110,000 gas-fired cars driven for a year. It also will curtail other harmful landfill pollution, such as lung-aggravating sulfur and cancer-causing benzene. Landfill operators will be required to keep better track of high temperatures and take steps to minimize the fire risks that heat could create. There are underground fires burning in at least two landfills in Southern California — smoldering chemical reactions that are incinerating buried garbage, releasing toxic fumes and spewing liquid waste. Regulators found explosive levels of methane emanating from many other landfills across the state.During the three-hour Air Resources Board hearing preceding the vote, several Californians who live near Chiquita Canyon Landfill — one of the known sites where garbage is burning deep underground — implored the board to act to prevent disasters in other communities across the state.“If these rules were already updated, maybe my family wouldn’t be sick,” said Steven Howse, a 27-year resident of Val Verde. “My house wouldn’t be for sale. My close friend and neighbor would still live next door to me. And I wouldn’t be pleading with you right now. You have the power to change this.”Landfill operators, including companies and local governments, voiced their concern about the costs and labor needed to comply with the regulation. “We want to make sure that the rule is implementable for our communities, not unnecessarily burdensome,” said John Kennedy, a senior policy advocate for Rural County Representatives of California, a nonprofit organization representing 40 of the state’s 58 counties, many of which own and operate landfills. “While we support the overarching goals of the rule, we remain deeply concerned about specific measures including in the regulation.”Lauren Sanchez, who was appointed chair of the California Air Resources Board in October, recently attended the United Nations’ COP30 climate conference in Brazil with Gov. Gavin Newsom. What she learned at the summit, she said, made clear to her that California’s methane emissions have international consequences, and that the state has an imperative to reduce them. “The science is clear, acting now to reduce emissions of methane and other short-lived climate pollutants is the best way to immediately slow the pace of climate change,” Sanchez said.

Exoplanet atmospheres are a key to habitability

The habitable zone of a planet might be key to whether life can survive there. But so are exoplanet atmospheres, scientists say. The post Exoplanet atmospheres are a key to habitability first appeared on EarthSky.

Artist’s concept of exoplanet GJ 9827 d. It might be a steam world, with lots of water vapor in its atmosphere. Astronomers say exoplanet atmospheres are a key to whether or not life could survive on a planet. Image via NASA/ ESA/ Leah Hustak (STScI)/ Ralf Crawford (STScI)/ University of Montreal. Scientists focus on the habitable zone (where liquid water might exist) when they are gauging whether an exoplanet could be habitable. But exoplanet atmospheres are also key to whether a planet can maintain stable, life-supporting conditions. For life to persist on a planet, the environment must be stable. A planet’s surface, oceans and atmosphere can work together to regulate the system. By Morgan Underwood, Rice University EarthSky isn’t powered by billionaires. We’re powered by you.Support EarthSky’s 2025 Donation Campaign and help keep science accessible. Exoplanet atmospheres are a key to habitability When astronomers search for planets that could host liquid water on their surface, they start by looking at a star’s habitable zone. Water is a key ingredient for life, and on a planet too close to its star, water on its surface may boil. Too far, and it could freeze. This zone marks the region in-between. But being in this sweet spot doesn’t automatically mean a planet is hospitable to life. Other factors, like whether a planet is geologically active or has processes that regulate gases in its atmosphere, play a role. The habitable zone provides a useful guide to search for signs of life on exoplanets, or planets outside our solar system orbiting other stars. But what’s in these planets’ atmospheres holds the next clue about whether liquid water – and possibly life – exists beyond Earth. The greenhouse effect On Earth, the greenhouse effect, caused by gases like carbon dioxide and water vapor, keeps the planet warm enough for liquid water and life as we know it. Without an atmosphere, Earth’s surface temperature would average around 0 degrees Fahrenheit (-18 C), far below the freezing point of water. The boundaries of the habitable zone are defined by how much of a greenhouse effect is necessary to maintain the surface temperatures that allow for liquid water to persist. It’s a balance between sunlight and atmospheric warming. Many planetary scientists, including me, are seeking to understand if the processes responsible for regulating Earth’s climate are operating on other habitable-zone worlds. We use what we know about Earth’s geology and climate to predict how these processes might appear elsewhere. That is where my geoscience expertise comes in. Picturing the habitable zone of a solar system analog, with Venus- and Mars-like planets outside of the “just right” temperature zone. Image via NASA. Why the habitable zone? The habitable zone is a simple and powerful idea, and for good reason. It provides a starting point, directing astronomers to where they might expect to find planets with liquid water. But without needing to know every detail about the planet’s atmosphere or history. Its definition is partially informed by what scientists know about Earth’s rocky neighbors. Mars, which lies just outside the outer edge of the habitable zone, shows clear evidence of ancient rivers and lakes where liquid water once flowed. Similarly, Venus is currently too close to the sun to be within the habitable zone. Yet, some geochemical evidence and modeling studies suggest Venus may have had water in its past. Though how much and for how long remains uncertain. These examples show that while the habitable zone is not a perfect predictor of habitability, it provides a useful starting point. How to have a stable environment What the habitable zone doesn’t do is determine whether a planet can sustain habitable conditions over long periods of time. On Earth, a stable climate allowed life to emerge and persist. Liquid water could remain on the surface, giving slow chemical reactions enough time to build the molecules of life. This let early ecosystems develop resilience to change, which reinforced habitability. Life emerged on Earth, but continued to reshape the environments it evolved in, making them more conducive to life. This stability likely unfolded over hundreds of millions of years, as the planet’s surface, oceans and atmosphere worked together as part of a slow but powerful system to regulate Earth’s temperature. Recycling inorganic carbon A key part of this system is how Earth recycles inorganic carbon between the atmosphere, surface and oceans over the course of millions of years. Inorganic carbon refers to carbon bound in atmospheric gases, dissolved in seawater or locked in minerals, rather than biological material. This part of the carbon cycle acts like a natural thermostat. When volcanoes release carbon dioxide into the atmosphere, the carbon dioxide molecules trap heat and warm the planet. As temperatures rise, rain and weathering draw carbon out of the air and store it in rocks and oceans. If the planet cools, this process slows down. This allows carbon dioxide, a warming greenhouse gas, to build up in the atmosphere again. This part of the carbon cycle has helped Earth recover from past ice ages and avoid runaway warming. Even as the sun has gradually brightened, this cycle has contributed to keeping temperatures on Earth within a range where liquid water and life can persist for long spans of time. Similar cycles in exoplanet atmospheres? Now, scientists are asking whether similar geological processes might operate on other planets. And if so, how they might detect them. For example, if researchers could observe enough rocky planets in their stars’ habitable zones, they could look for a pattern connecting the amount of sunlight a planet receives and how much carbon dioxide is in its atmosphere. Finding such a pattern may hint that the same kind of carbon-cycling process could be operating elsewhere. The mix of gases in a planet’s atmosphere is shaped by what’s happening on or below its surface. One study shows that measuring atmospheric carbon dioxide in a number of rocky planets could reveal whether their surfaces are broken into a number of moving plates, like Earth’s, or if their crusts are more rigid. On Earth, these shifting plates drive volcanism and rock weathering, which are key to carbon cycling. Simulation of what space telescopes, like the Habitable Worlds Observatory, will capture when looking at distant solar systems. Image via STScI/ NASA GSFC. Keeping an eye on distant exoplanet atmospheres The next step will be toward gaining a population-level perspective of planets in their stars’ habitable zones. By analyzing atmospheric data from many rocky planets, researchers can look for trends that reveal the influence of underlying planetary processes, such as the carbon cycle. Scientists could then compare these patterns with a planet’s position in the habitable zone. Doing so would allow them to test whether the zone accurately predicts where habitable conditions are possible, or whether some planets maintain conditions suitable for liquid water beyond the zone’s edges. This kind of approach is especially important given the diversity of exoplanets. Many exoplanets fall into categories that don’t exist in our solar system. These include super Earths and mini Neptunes. Others orbit stars smaller and cooler than the sun. NASA’s Habitable Worlds Observatory The datasets needed to explore and understand this diversity are just on the horizon. NASA’s upcoming Habitable Worlds Observatory will be the first space telescope designed specifically to search for signs of habitability and life on planets orbiting other stars. It will directly image Earth-sized planets around sunlike stars to study their atmospheres in detail. Instruments on the observatory will analyze starlight passing through these atmospheres to detect gases like carbon dioxide, methane, water vapor and oxygen. As starlight filters through a planet’s atmosphere, different molecules absorb specific wavelengths of light, leaving behind a chemical fingerprint that reveals which gases are present. These compounds offer insight into the processes shaping these worlds. The Habitable Worlds Observatory is under active scientific and engineering development, with a potential launch targeted for the 2030s. Combined with today’s telescopes, which are increasingly capable of observing atmospheres of Earth-sized worlds, scientists may soon be able to determine whether the same planetary processes that regulate Earth’s climate are common throughout the galaxy, or uniquely our own. NASA’s planned Habitable Worlds Observatory will look for exoplanets that could potentially host life.

Some California landfills are on fire and leaking methane. Newly proposed rules could make them safer

California is considering adopting new rules to better identify and more quickly to respond to dangerous methane leaks and underground fires at landfills statewide.

A vast canyon of buried garbage has been smoldering inside a landfill in the Santa Clarita Valley, inducing geysers of liquid waste onto the surface and noxious fumes into the air.In the Inland Empire, several fires have broken out on the surface of another landfill. In the San Fernando Valley, an elementary school has occasionally canceled recess due to toxic gases emanating from rain-soaked, rotting garbage from a nearby landfill. And, in the San Francisco Bay Area, burrowing rodents may be digging into entombed trash at a landfill-turned-park, unloosing explosive levels of methane.These are just a few of the treacherous episodes that have recently transpired at landfills in California, subjecting the state’s waste management industry to growing scrutiny by residents and regulators.Landfill emissions — produced by decaying food, paper and other organic waste — are a major source of planet-warming greenhouse gases and harmful air pollution statewide. But mismanagement, aging equipment and inadequate oversight have worsened this pollution in recent years, according to environmental regulators and policy experts.This week, the California Air Resources Board will vote on adopting a new slate of requirements to better identify and more quickly respond to methane leaks and disastrous underground fires at large landfills statewide.The proposal calls for using satellites, drones and other new technologies to more comprehensively investigate methane leaks. It also would require landfill operators to take corrective action within a few days of finding methane leaks or detecting elevated temperatures within their pollution control systems.In recent years, state regulators have pinpointed at least two landfills in Southern California experiencing “rare” underground landfill fires — largely uncontrollable disasters that have burned troves of buried garbage and released toxic fumes into the air. More recently, a new state satellite program has detected 17 methane plumes from nine landfills between July and October, potentially leaking the flammable gas into unwanted areas and contributing to climate change.Proponents of the proposed rule say the added oversight could help reduce California’s second-largest source of methane, a potent greenhouse gas that warms the atmosphere much more than carbon dioxide. It could also bring relief to hundreds of thousands of people who live nearby landfills and may be exposed to toxic pollutants like hydrogen sulfide or benzene.“Curbing methane emissions is a relatively quick and cost-effective way to reduce the greenhouse pollution that’s wreaking havoc with our climate,” said Bill Magavern, policy director at the Coalition for Clean Air. “But [we’ve] also been involved in updating and strengthening the rule because we’re seeing the community impacts of leaking landfills, particularly at places like Chiquita Canyon, where we have a landfill fire that is making people in the community sick.”Nearly 200 landfills statewide would be subject to the proposed requirements — 48 are privately owned and 140 are government-owned.Many landfill operators oppose the rule, saying the new requirements would saddle the industry with an untenable workload and millions of dollars each year in added costs. These costs could be passed on to residents, whose garbage fees have already risen significantly in recent years.Sacramento County officials, who operate the Kiefer Landfill, said the proposed protocols were not feasible. “As a public landfill, Kiefer cannot quickly adapt to regulatory shifts of this magnitude, and these increased costs would ultimately burden the community it serves,” Sacramento County officials wrote in a Nov. 10 letter to the state Air Resources Board.The vast majority of landfills are already required to monitor for leaks and operate a gas collection system — a network of wells that extend deep into the layers of buried waste to capture and destroy methane.A hot messChiquita Canyon Landfill in Castaic has become the poster child for the issues plaguing California’s waste management system.A blistering-hot chemical reaction began inside the landfill’s main canyon in May 2022, roasting garbage in a roughly 30-acre area.Starting in April 2023, residents of Castaic and nearby Val Verde began to take notice. They called in thousands of odor complaints to the South Coast Air Quality Management District, with many citing headaches, nausea, nosebleeds and difficulty breathing.Later that year, state regulators learned that the landfill’s temperatures had risen above 200 degrees, melting plastic pipes used to collect landfill gases. An air district inspector also witnessed geysers of liquid waste bursting onto the surface and white smoke venting from large cracks spreading across the reaction area.Air sampling found elevated levels of lung-aggravating sulfur pollutants and cancer-causing benzene. Air samples in 2023 detected benzene concentrations more than eight times higher than the state’s short-term health limit at Hasley Canyon Park, which abuts Live Oak Elementary School, alarming local parents.“I personally have transferred my children to different schools further away,” said Jennifer Elkins, a Val Verde resident whose children attended Live Oak. “I spend three hours a day driving my kids to and from school. The commute has been a sacrifice, but it’s also been well worth it, because I know my children are breathing cleaner air, and I have seen their health improve.”The landfill, owned by Texas-based Waste Connections, installed new heat-resistant equipment to extract liquid waste in an attempt to reduce broiling temperatures. It also installed a large covering over the affected area to suppress odors. It permanently closed and ceased accepting waste this year.Still, the reaction area has tripled in size and could consume the entire 160-acre canyon for many more years. During other underground landfill fires, elevated temperatures have persisted for more than a decade.The issue is, once these broiling temperatures start consuming landfill waste, there’s little that landfill operators can do to snuff them out.The fumes from Chiquita Canyon have pushed some longtime residents to consider moving. After more than 25 years in Val Verde, Abigail DeSesa is contemplating starting anew somewhere else.“This is our life’s investment — our forever home that we were building for retirement and on the verge of paying off,” DeSesa said. “And we may have to start over.”“I don’t know that I can outlast it,” DeSesa added.Chiquita Canyon is not alone.Earlier this year, the South Coast air district learned about another fiery chemical reaction brewing inside El Sobrante Landfill in Corona. In August, Waste Management, the landfill’s owner and operator, acknowledged there was a two-acre “area of concern” where landfill staff had observed temperatures climbing above 200 degrees. Riverside County inspectors also found several fires had ignited on the landfill’s surface in recent years, according to public records.Environmental advocates fear that many more landfills may be on the precipice of these largely unmanageable disasters.According to an analysis by California Communities Against Toxics, there are 18 landfills in California that have had prolonged heat signatures detected by NASA’s Fire Information for Resource Management System, an online tool using satellite instruments to detect fires and thermal anomalies.At least 11 of these landfills requested and received permission from either federal or local environmental regulators to continue operating with higher temperatures than currently allowed, according to public records obtained by the environmental organization.These regulatory exemptions are part of the problem, said Jane Williams, the group’s executive director.“We have 11 landfills across California that have been granted waivers by the government to basically ‘hot rod’ the landfill,” Williams said. “We would really like EPA and state agencies to stop granting landfill waivers. It’s a permission slip to speed in a school zone.”Under newly proposed revisions to state rules, operators must be more transparent in disclosing the temperatures in their gas collection systems. If operators detect elevated temperatures, they must take action to minimize the amount of oxygen in the landfill.While these rule changes might be coming too late to fix the issues near Chiquita Canyon, locals hope it will help others who live in the orbit of the nearly 200 other large landfills in California that could be subject to these rules.“While there’s still a fight here to try to address the concerns at Chiquita Canyon Landfill, we know that there’s an opportunity to really prevent this kind of disaster from happening anywhere else in our state,” said Assemblymember Pilar Schiavo.Dangerous leaksMeanwhile, many other landfills are releasing unsafe amounts of methane, an odorless gas produced by bacteria that break down organic waste.These emissions present two critical issues.First, methane is a powerful greenhouse gas — capable of warming the atmosphere 80 times more than the same amount of carbon dioxide over 20 years. Following California’s large dairy and livestock operations, landfills emit the second-most methane statewide.Second, methane is the primary constituent in natural gas. It can ignite or explode at certain concentrations, presenting a serious safety risk in the event of uncontrolled releases. Several times over the last few years, regulators have detected potentially explosive concentrations in the air and shallow soil near several landfills.Under current landfill regulations, operators are required to monitor for excessive methane leaks four times a year. Many operators hire contractors to walk across accessible portions of the landfill with a handheld leak-monitoring device, an approach that some environmental advocates say is unreliable.In addition, some areas of the landfill are not screened for methane leaks if operators consider them to be unsafe to walk across, due to, for example, steep hills or ongoing construction activities.“Landfills have to monitor surface emissions, but they do that in a very inefficient way, using outdated technology,” Magavern said.Starting this past summer, California has partnered with the nonprofit organization Carbon Mapper to use satellites to detect methane leaks, and already has found 17 coming from landfills. In one case, researchers saw a large methane plume appear to emanate from Newby Island Landfill in San José and drift into a nearby residential neighborhood.Although the state has notified these landfill operators, it currently cannot require them to repair leaks detected via satellite. That would change under the proposed amendments to the state’s landfill regulations. Operators would also have to use state-approved technology to routinely scan portions of their landfills they deem inaccessible.The proposed amendments seek to prevent the most common causes of methane emissions. A series of surveys of landfill operators found 43% of leaks in recent years were caused by one or more of a facility’s gas collection wells being offline at the time.The new rules would require that such wells can only be offline for up to five days at a time for repairs. Operators would also be required to install gas collection systems within six months of when garbage is first placed in a new part of a landfill — rather than the 18-month time frame currently allowed.In addition, landfills would be forced to take actions to fix a leak within three days of detection, rather than 10 days. In theory, that should help reduce the risk of leaks from things like cracks in landfill covers (typically a layer of soil or plastic covering) and damaged components of gas collection systems — two other major sources of leaks that landfill operators have reported.The amended landfill rules could collectively cost private companies and local governments $12 million annually.Some say that’s well worth the cost.A contingent of residents who live near Chiquita Canyon Landfill are flying to Sacramento to attend the state Air Resources Board meeting. They are expected to testify on how the fire and landfill emissions have unraveled the fabric of the semi-rural community.Elkins, the Val Verde resident, appreciated the area’s natural beauty — picturesque hillsides, wildlife and opportunities for stargazing without bright city lights. However, now her family hardly spends any time outdoors due to the noxious odors.Some of her neighbors have moved away, but Elkins and many other longtime locals cannot, no matter how they fear for their health and safety. “The homes are not selling,” she said. “Other homes sit vacant, and community members are paying two mortgages just to get away. And for many of us, it would be financial suicide to move away and start over somewhere new.”

New Texas petrochemical facilities are mostly in low income areas, communities of color, study finds

Researchers evaluated the neighborhoods around 89 proposed or expanding petrochemical facilities across the state using a screening tool from the EPA.

Phillip)A recent report from Texas Southern University found that new and expanding petrochemical facilities in Texas are overwhelmingly located in low-income neighborhoods and communities of color. Researchers evaluated the neighborhoods around 89 proposed or expanding petrochemical facilities across the state using a screening tool from the Environmental Protection Agency. They looked at air pollution and proximity to other "hazardous facilities" in the areas. Data related to the race, education, income level and languages within the areas was also collected. Sign up for the Hello, Houston! daily newsletter to get local reports like this delivered directly to your inbox. "The communities that are on the fenceline are getting pollution and they also are getting poverty," said Robert Bullard, one of the study's authors. "And also, if you look at the infrastructures within those neighborhoods that have these facilities, they are of poor quality." The report found that 9 in 10 of the facilities are located in counties with "higher demographic vulnerability" – meaning they had more people of color, more low-income residents, or both, compared to the state and national averages. Over half of the new facilities were slated to be built in communities that have a higher proportion of people of color than the national average. Meanwhile, 30% of the facilities were slated to be built in areas with a poverty rate higher than the national average. "Segregation and racial redlining actually segregated pollution, and it segregated people," Bullard said. The analysis also found that the proposed facilities were being built in areas that are already struggling with air pollution. About 1 in 5 of the proposed facilities are located within the top 10% of areas nationwide with the highest amount of particulate matter pollution, and 46% of the new facilities are slated to be built within the top 10% of communities across the country with the highest amount of air toxins. The facilities were concentrated in 9% of Texas counties, with nearly half of them located in Harris County or Jefferson County.
