The One Key Piece Missing From NYC’s Congestion Car Toll

News Feed
Monday, March 18, 2024

A nurse boarded the Bx18A bus, whose route circles between the Morris Heights and Highbridge neighborhoods of the Bronx. Having an anxious moment most New Yorkers will find relatable, she began hunting through her purse to look for her MetroCard to pay for her ride. When the driver pointed to a sign indicating that this was a “fare free” bus—part of an experiment in free public transit created by the state legislature last year—the nurse started dancing.I’d like to have what she’s having, please. I think we all would. “She cha-cha’d down the bus,” said Assemblyman Zohran Mamdani Thursday, telling the story in a speech on the New York Assembly floor. Mamdani was introducing his “Get Congestion Pricing Right” bill, which he said would “expand that feeling—of joy, of relief” by making 15 more bus routes free, across the city, as well as increasing bus frequency. Over the next couple weeks, the bill will be part of the always-harrowing negotiations with Governor Kathy Hochul and among the state legislators. Mamdani called his bill “Get Congestion Pricing Right” in part because, right now, New York risks getting it wrong: Few good ideas have been resisted as loudly as New York’s plan to charge a toll to drivers entering Manhattan ($15 for most) and use the money to improve public transit. The policy, set to take effect June 15, has been mocked, attacked, and misrepresented for years. Now that it’s finally happening, it’s crucial that it work well for the majority of New Yorkers. Otherwise, backlash could quickly sink the policy and discourage similar efforts in the future—in New York and elsewhere. For congestion pricing to work, as Mamdani clearly understands, public transit needs to be good enough to present a viable alternative to the $15 toll. Having fewer cars on the roads is demonstrably fantastic for the environment, public health, and quality of life. In Stockholm, congestion pricing has reduced carbon emissions by 20 percent. In London, it has reduced the nitrogen oxides and particulates in the air by 12 percent. Cleaner air will in turn improve health of New Yorkers: In Stockholm, congestion pricing cut the number of asthma-related hospital visits in half. Reducing traffic—the MTA estimates the plan will cut traffic by 17 percent—will also ease the stress of driving for anyone who has to do so, and make much of the city more pleasant for pedestrians, especially crucial since New Yorkers walk more than any other group of Americans. Reducing traffic will also save lives: Since emergency vehicles are among the few exempted from the toll, they will presumably be able to move more quickly to put out fires and get people to the hospital.  Congestion pricing will also raise $1 billion a year for the public transit system, allowing the MTA to make the kinds of improvements that will save New Yorkers money, time, and irritation. These improvements will also boost ridership; this will make the subway safer, which will, in turn, boost ridership further.Yet congestion pricing has received a great deal of pseudo-populist mockery and resistance. The New York Post has run negative articles on the topic on an almost daily basis (“Congestion Pricing Will Leave NYC in a Jam” and “Time for Congestion Pricing to Hit the Road”  are just two recent headlines). The policy has faced lawsuits from city workers’ unions, the governor of New Jersey, the mayor of Fort Lee, New Jersey, the Staten Island borough president, and a range of other injured parties. The gist of all the criticism is that the policy will hurt ordinary hardworking New Yorkers. Although New York’s policy does still have flaws that must be fixed—insufficient exemptions for low-income drivers, for instance—the populist argument against congestion pricing is mostly disingenuous. Only 4 percent of outer-borough New Yorkers drive to Manhattan to work; 57 percent take public transit. And only 2 percent of low-income outer-borough New Yorkers, specifically, would be asked to pay a congestion fee as part of their commute; 61 percent take public transit. As we’ve seen in France with the “gilet jaune” movement, in which motorists wore yellow vests and blocked highways to protest an unpopular gas tax in 2018, and the more recent farmer protests against the European Union’s effort to limit harmful pesticides, this kind of populist anti-environmental argument resonates when large numbers of ordinary people don’t feel their material needs have been considered by the elites in charge. Congestion pricing carries precisely this kind of baggage, even though it will improve our lives in many ways. That means the big question politically, the one that will determine congestion pricing’s longevity as a policy, is whether the vast majority of New Yorkers will experience its benefits and how quickly. We must see the positive results of congestion pricing in our own lives to balance out the rage induced by what behavioral economists call “the pain of paying” (research shows that we are far more bothered about small expenses that we pay frequently and can see, like milk or gas, than about bigger expenses we don’t pay often or that are simply deducted from our paychecks, like our health insurance premiums). Unfortunately, we can’t see or feel reductions in carbon emissions. Clean air is more ambiguous. We do notice pollution. We freak out about bad air quality warnings in the summer. And last year when the smoke from the Canadian wildfires turned New York City’s skies red and smoky, I saw children running out of school buildings to gape at it in terror. Some of us will undoubtedly feel, over time, that our asthma or headaches have improved, or that we are breathing more easily. But it’s possible that for many people, the clean air might be an invisible benefit, the kind that is politically troublesome because it doesn’t reward its architects. By contrast, New Yorkers have in recent years been complaining about the subway a lot and will notice if it gets better. Public transit is one of the least abstract political issues for New Yorkers, affecting where we can work, whether we can get there in time, and whether we can pick up our kids on time at the end of the day. Ridership has suffered since the pandemic. Sensationally reported crimes on the subway have contributed to anxiety about the system, which New York’s governor has idiotically played into by sending in the National Guard. Less dramatic but perhaps far more frustrating to most people, the service has deteriorated recently, with more delays and disruptions, and even derailments, which are quite scary. The political reception of congestion pricing, then, will be mostly determined by how tangibly it improves our transit system. Of course, there’s no evading the biggest problem with congestion pricing, which is that people hate being forced to change cherished habits. New York City is a great place to implement this policy, since it’s already a terrible city for motorists, the transit system goes almost everywhere, and many New Yorkers already avoid driving. But those who are attached to their cars will be vocal in their objections. Such gripes will resonate and spread like a contagion if people don’t see the positive effects of congestion pricing right away.That’s why immediate measures like Assemblyman Mamdani’s “Get Congestion Pricing Right” proposal—making more bus routes free and more frequent, before the revenue from congestion pricing even kicks in—are so crucial. Good environmental policy prods us to change our behavior while making our lives better at the same time. Congestion pricing will do this: It will obligate driving less by forcing cost-benefit analysis of our car trips, while also rewarding us by transforming urban life for the better—not just with cleaner air and better health, but by ensuring that we all waste less of our lives sitting in traffic. But the biggest benefit for most people will be the investments in our transit system, making a safer, more convenient, and joyful experience. If more of us start feeling anything close to the happiness that nurse felt on the Bx18A that day, congestion pricing will be a lasting political success.

The Pregnancy Pill Millions Trust Faces Alarming New Questions About Child Brain Health

Scientists are warning that one of the most trusted painkillers used in pregnancy may not be as safe as once believed.

New research raises red flags about acetaminophen use in pregnancy, linking it to autism and ADHD risks in children. ShutterstockScientists are warning that one of the most trusted painkillers used in pregnancy may not be as safe as once believed. A sweeping review of studies finds links between prenatal acetaminophen exposure and higher risks of autism and ADHD in children. The medication crosses the placenta and may interfere with brain development, raising urgent questions about clinical guidelines. Acetaminophen in Pregnancy Linked to Neurodevelopmental Risks Scientists at the Icahn School of Medicine at Mount Sinai report that children exposed to acetaminophen before birth may face a greater chance of developing neurodevelopmental conditions such as autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD). Their findings, published in BMC Environmental Health, mark the first time that the Navigation Guide methodology has been applied to thoroughly assess the quality and reliability of the research on this subject. Acetaminophen (commonly sold as Tylenol® in the United States and Canada, and known as paracetamol elsewhere) is the most widely used non-prescription treatment for pain and fever during pregnancy, taken by more than half of expectant mothers worldwide. For decades, it has been viewed as the safest option for relief from headaches, fever, and general pain. However, the Mount Sinai team’s review of 46 studies, which together involved over 100,000 participants from multiple countries, challenges this long-standing belief and highlights the importance of caution and additional investigation. Gold-Standard Review Methodology Applied The research team relied on the Navigation Guide Systematic Review, a leading framework used in environmental health. This method enables scientists to systematically evaluate each study, rating potential sources of bias such as incomplete data or selective reporting, while also weighing the overall strength and consistency of the evidence. “Our findings show that higher-quality studies are more likely to show a link between prenatal acetaminophen exposure and increased risks of autism and ADHD,” said Diddier Prada, MD, PhD, Assistant Professor of Population Health Science and Policy, and Environmental Medicine and Climate Science, at the Icahn School of Medicine at Mount Sinai. “Given the widespread use of this medication, even a small increase in risk could have major public health implications.” Possible Biological Mechanisms Behind the Link The paper also explores biological mechanisms that could explain the association between acetaminophen use and these disorders. Acetaminophen is known to cross the placental barrier and may trigger oxidative stress, disrupt hormones, and cause epigenetic changes that interfere with fetal brain development. While the study does not show that acetaminophen directly causes neurodevelopmental disorders, the research team’s findings strengthen the evidence for a connection and raise concerns about current clinical practices. Call for Updated Guidelines and Safer Alternatives The researchers call for cautious, time-limited use of acetaminophen during pregnancy under medical supervision; updated clinical guidelines to better balance the benefits and risks; and further research to confirm these findings and identify safer alternatives for managing pain and fever in expectant mothers. “Pregnant women should not stop taking medication without consulting their doctors,” Dr. Prada emphasized. “Untreated pain or fever can also harm the baby. Our study highlights the importance of discussing the safest approach with health care providers and considering non-drug options whenever possible.” Rising Autism and ADHD Rates Add Urgency With diagnoses of autism and ADHD increasing worldwide, these findings have significant implications for public health policy, clinical guidelines, and patient education. The study also highlights the urgent need for pharmaceutical innovation to provide safer alternatives for pregnant women.

Farm Workers At Risk For Kidney Disease

By Dennis Thompson HealthDay ReporterTHURSDAY, Oct. 2, 2025 (HealthDay News) — Farm workers have a higher risk for kidney disease, mainly due to exposure to high heat and agricultural chemicals, a new small-scale study says.Workers on a grape farm near the Arizona-Sonora border had high levels of arsenic, cadmium and chromium in their urine, and those were linked to increased signs of kidney injury, according to findings published in the November issue of the journal Environmental Research.“We’re seeing an increase in kidney disease in young people who lack typical risk factors, especially in hotter regions,” said lead researcher Rietta Wagoner, a postdoctoral scholar at the University of Arizona.“There is evidence that heat, pesticides and metal exposures each play a role, and especially that heat is making potentially toxic exposures worse,” she said in a news release. “Each individually has been studied, but little research has examined a combination of factors. This study is an attempt to answer questions." For the study, researchers followed 77 farm workers who traveled seasonally from southern Mexico to work the grape farm. The workers arrived in February and March, at the beginning of the grape season, and stayed until the end of summer.The team collected daily urine and blood samples from the workers, and measured their heat stress twice a day with inner ear temperatures and heart rates.The worker’s kidney function generally decreased during the season, based on estimates derived from blood and urine samples.This decline was linked to chemicals found in pesticides and fertilizers, as well as the excessive summer heat in the Sonoran Desert, where air temperatures ranged upwards of 100 degrees Fahrenheit, researchers said.“When we looked at heat in combination with metals and metalloids, we found heat especially exacerbated the effects of the metals arsenic and cadmium on the kidney,” Wagoner said. “In other words, together, the effects were worse.”This kidney damage can be prevented, she said.“We recommend mandatory periodic breaks and rest built into the workday,” Wagoner said. “Provide water, electrolyte replacement and have restrooms nearby. Also, allow the workers time to get used to the conditions.”It’s also important to get to the source of workers’ exposure to these toxic metals, she said, noting that workers drink well water in places where uranium and arsenic are found in the soil.“If we can implement prevention measures early on,” Wagoner said, “we can prevent longer term issues.”SOURCES: University of Arizona, news release, Sept. 23, 2025; Environmental Research, November 2025What This Means For YouFarm workers should make sure to take frequent rest breaks during hot days and stay hydrated.Copyright © 2025 HealthDay.

Giant Sinkhole in Chilean Mining Town Haunts Residents, Three Years On

TIERRA AMARILLA (Reuters) -Residents in the mining town of Tierra Amarilla in the Chilean desert are hopeful that a new court ruling will allay their fears about a giant sinkhole that opened near their homes more than three years ago and remains unfilled.A Chilean environmental court this month ordered Minera Ojos del Salado, owned by Canada's Lundin Mining, to repair environmental damage related to activity at its Alcaparrosa copper mine, which is thought to have triggered the sinkhole that appeared in 2022.The ruling calls on the company to protect the region's water supply and refill the sinkhole. The cylindrical crater originally measured 64 meters (210 ft) deep and 32 meters (105 ft) wide at the surface.That has provided a small measure of relief to those in arid Tierra Amarilla in Chile's central Atacama region, who fear that without remediation the gaping hole could swallow up more land."Ever since the sinkhole occurred ... we've lived in fear," said Rudy Alfaro, whose home is 800 meters from the site. A health center and preschool are nearby too, she said."We were afraid it would get bigger, that it would expand, move toward the houses." The sinkhole expelled clouds of dust in a recent earthquake, provoking more anxiety, she said.     The court upheld a shutdown of the small Alcaparrosa mine ordered by Chile's environmental regulator in January, and confirmed "irreversible" damage to an aquifer, which drained water into the mine and weakened the surrounding rock."This is detrimental to an area that is already hydrologically stressed," said Rodrigo Saez, regional water director. Lundin said it will work with authorities to implement remediation measures.(Writing by Daina Beth Solomon, Editing by Rosalba O'Brien)Copyright 2025 Thomson Reuters.

Scientists Warn: Bottled Water May Pose Serious Long-Term Health Risks

Using it regularly introduces tens of thousands of microplastic and nanoplastic particles into the body each year.

A scientist’s island epiphany uncovers how single-use bottles shed micro- and nanoplastics that infiltrate the body, with emerging evidence of chronic harm and measurement blind spots. Credit: ShutterstockUsing it regularly introduces tens of thousands of microplastic and nanoplastic particles into the body each year. The tropical beauty of Thailand’s Phi Phi islands is not the kind of place where most PhD journeys begin. For Sarah Sajedi, however, it was not the beaches themselves but what lay beneath them that sparked her decision to leave a career in business and pursue academic research. “I was standing there looking out at this gorgeous view of the Andaman Sea, and then I looked down and beneath my feet were all these pieces of plastic, most of them water bottles,” she says. “I’ve always had a passion for waste reduction, but I realized that this was a problem with consumption.” Sajedi, BSc ’91, decided to return to Concordia to pursue a PhD with a focus on plastic waste. As the co-founder of ERA Environmental Management Solutions, a leading provider of environmental, health, and safety software, she brought decades of experience to compliment her studies. Her latest paper, published in the Journal of Hazardous Materials, looks at the science around the health risks posed by single-use plastic water bottles. They are serious, she says, and seriously understudied. Sarah Sajedi with Chunjiang An: “Drinking water from plastic bottles is fine in an emergency but it is not something that should be used in daily life.” Tiny threats, little known In her analysis of more than 140 scientific papers, Sajedi reports that people ingest an estimated 39,000 to 52,000 microplastic particles each year. For those who rely on bottled water, that number climbs even higher—about 90,000 additional particles compared to individuals who primarily drink tap water. These particles are invisible to the eye. Microplastics range in size from one micron (a thousandth of a millimeter) to five millimeters, while nanoplastics are smaller than a single micron. They are released as plastic bottles are manufactured, stored, transported, and gradually degrade. Because many bottles are made from low-grade plastic, they shed particles whenever they are handled or exposed to sunlight and changes in temperature. Unlike plastics that move through the food chain before entering the human body, these are consumed directly from the container itself. Sarah Sajedi and Chunjiang An.

Once inside the body, these small plastics can pass through biological barriers, enter the bloodstream, and reach major organs. Their presence may contribute to chronic inflammation, cellular oxidative stress, hormone disruption, reproductive issues, neurological damage, and some cancers. Still, their long-term impacts are not fully understood, largely because of limited testing and the absence of standardized ways to measure and track them. Sajedi also outlines the range of methods available to detect nano- and microplastics, each with benefits and limitations. Some approaches can locate particles at extremely small scales but cannot reveal their chemical makeup. Others identify the material composition but overlook the tiniest plastics. The most sophisticated and dependable tools are often prohibitively expensive and not widely accessible. Education is the best prevention Sajedi is encouraged by the legislative action that has been adopted by governments around the world aimed at limiting plastic waste. However, she notes that the most common targets are single-use plastic bags, straws, and packaging. Very few address the pressing issue of single-use water bottles. “Education is the most important action we can take,” she says. “Drinking water from plastic bottles is fine in an emergency but it is not something that should be used in daily life. People need to understand that the issue is not acute toxicity—it is chronic toxicity.” Reference: “Unveiling the hidden chronic health risks of nano- and microplastics in single-use plastic water bottles: A review” by Sarah Sajedi, Chunjiang An and Zhi Chen, 14 June 2025, Journal of Hazardous Materials.DOI: 10.1016/j.jhazmat.2025.138948 Funding: Natural Sciences and Engineering Research Council of Canada Never miss a breakthrough: Join the SciTechDaily newsletter.Follow us on Google, Discover, and News.
