Researchers at the University of Virginia have developed a scalable method for fabricating MOF-525, a material that can effectively capture and convert carbon dioxide into useful chemicals. This breakthrough offers a practical solution for large-scale applications in carbon capture and conversion, presenting significant environmental and energy benefits.

Scientists have figured out how to take a miracle material, one capable of extracting value from captured carbon dioxide, and do what no one else has: make it practical to fabricate for large-scale application.

The breakthrough from chemical engineering assistant professor Gaurav “Gino” Giri’s lab group has implications for the cleanup of the greenhouse gas, a major contributor to the climate change dilemma. It could also help solve the world’s energy needs.

The Power of MOF-525

The substance, called MOF-525, is in a class of materials called metal-organic frameworks.

“If you can make these MOFs cover large areas, then new applications become possible, like making a membrane for carbon capture and electrocatalytic conversion all in one system,” Giri said.

Electrocatalytic conversion creates a bridge from renewable energy sources to direct chemical synthesis, taking the burning of carbon dioxide-producing fossil fuels out of the equation.

What gives MOFs superpowers is their ultra-porous, crystalline structures — 3D networks of minute nanoscale cavities that create vast internal surface area and act like a sponge — that can be designed to trap all sorts of chemical compounds.

Giri’s group reasoned that starting with an inherently scalable synthesis technique — solution shearing — would better their odds. They had already had success shearing simpler MOFs.

In Giri’s process, the MOF’s components are mixed in a solution, and then spread across a substrate with the shearing blade. As the solution evaporates, chemical linkages form the MOF as a thin film on the substrate. Applying MOF-525 in this way produces an all-in-one membrane for carbon trapping and conversion.

‘Chronic threat’ of PFAS firefighting foams raised in 2003 secret UK report

Exclusive: Environment Agency warned about ‘forever chemicals' 20 years before it started to regulate themThe Environment Agency was warned about the “chronic threat” that firefighting foams containing PFAS “forever chemicals” pose to the environment in 2003, 20 years before it started the process of regulating the chemicals, it can be revealed.In a 200-page report obtained by the Ends Report via a freedom of information request and shared with the Guardian, consultants commissioned by the Environment Agency conducted an environmental review of firefighting foams with a “particular emphasis on their fluorosurfactant content”.

The Environment Agency was warned about the “chronic threat” that firefighting foams containing PFAS “forever chemicals” pose to the environment in 2003, 20 years before it started the process of regulating the chemicals, it can be revealed.In a 200-page report obtained by the Ends Report via a freedom of information request and shared with the Guardian, consultants commissioned by the Environment Agency conducted an environmental review of firefighting foams with a “particular emphasis on their fluorosurfactant content”.Fluorosurfactants are a type of PFAS – a group of about 10,000 chemicals linked to a wide range of serious illnesses, including certain cancers. They are now known as “forever chemicals” because they do not break down in the environment.The report, which was never made publicly available, was intended for use to formulate Environment Agency policy “in order to minimise environmental harm arising from the use of firefighting foams”.The introduction to the report says: “When firefighting foams are released into the environment, whether it is through emergency use, training exercise or accidental spills, they may have an adverse effect on local environmental conditions and resident organisms.”More than 20 years later, firefighters in the UK are only now starting to realise that they have spent decades being exposed to these toxic chemicals, and residents of a town that is home to a major manufacturer of the foams are asking why the Environment Agency did not warn them about the long-term health and environmental impact of the chemicals.Around the world, the net has been tightening around PFAS. The US recently introduced strict limits on six PFAS chemicals regularly found in drinking water, and the EU is planning to restrict the use of about 10,000 PFAS. However, in England and Wales there are no specific standards for PFAS in drinking water regulations, and in the UK only two types of PFAS – PFOS and PFOA – are regulated. The Health and Safety Executive launched a consultation on plans to restrict the use of PFAS in firefighting foams in April this year.Having reviewed the product data sheets of the three firefighting foam producers located in the UK at the time – which included Angus Fire, whose factory is located in Bentham in North Yorkshire, the most PFAS-polluted place known in the UK – the report authors concluded that a number of the constituents in the foams were “toxic, persistent and possibly bioaccumulative”.Therefore, they said, there “appears to be a discrepancy” between the general low toxicity and biodegradability of the final product and the persistence of the foam constituents.The report goes on to explain that this is probably because these chemicals are present in low concentrations. However, the authors wrote that if these “minor constituents persist and/or bioaccumulate … they may have a long-term effect on the environment even after the cessation of firefighting operations”.They added: “In such circumstances the constituents of foams may pose a chronic threat to aquatic organisms.”Responding to the report, Dr Shubhi Sharma, of the charity Chem Trust, said: “It is shocking to hear that the Environment Agency was advised about the toxicity and persistence of PFAS-based firefighting foams, which have been linked to incidences of cancer in firefighters, over 20 years ago. This PFAS pollution scandal is due to inaction and regulatory failure.”In the report, the authors recognised that in emergency firefighting situations where the primary objective was to save lives and property, the environmental impacts of the foams were “obviously a secondary concern”. However, they stated that “when firefighting foams are used for training purposes, their environmental impact needs to be a higher priority”.Sean Comber, one of the original report authors, said that a number of years after the report was completed, the Environment Agency announced a type of environmental and human health limit on the concentration for PFOS. He said he “suspects” the 2003 report contributed to the agency prioritising the creation of this quality standard for PFOS.skip past newsletter promotionOur morning email breaks down the key stories of the day, telling you what’s happening and why it mattersPrivacy Notice: Newsletters may contain info about charities, online ads, and content funded by outside parties.

Neglect by successive governments and employers means that firefighters have been exposed to these chemicals for far too long.”La Torre said the fact that calls for research into firefighting foams and warnings of the dangers of PFAS “went ignored” back in 2003 was “a missed opportunity to protect the environment and safeguard lives”. “The government and fire service employers must take action to prevent further exposure to PFAS, and provide health monitoring for all firefighters,” he said.An Environment Agency spokesperson said: “We continue to develop our scientific understanding of PFAS, and our evidence and expert advice has been informing government policy in this area since the 2000s. Alongside the Health and Safety Executive, we are developing a wider restriction on the use of PFAS in firefighting foam through [the chemicals regulation body] UK Reach.”A spokesperson for the Department for Environment, Food and Rural Affairs said: “Britain’s nature is in crisis, which is why we have wasted no time in announcing a rapid review to deliver our legally binding environment targets to better protect our natural environment. This includes how best to manage the risks from PFAS. We have also already announced plans to restrict firefighting foams and will set out more detail in due course.”Angus Fire has not breached any rules in terms of the PFAS it has produced or tested at its Bentham site, and it stopped testing PFAS foams there in 2022. A spokesperson for the firm said: “It should be noted that the understanding and regulation of PFAS chemicals has evolved over time and Angus has always sought to fully comply with its regulatory obligations. Angus Fire customers were able to procure training foam to train their firefighters which do not contain PFAS chemicals.”

PFAS in Pesticides Could Pose a Greater Multigenerational Threat Than DDT

A looming and poorly regulated PFAS threat comes from these chemicals’ common use in pesticides on farms nationwide

September 11, 20244 min read‘Forever’ Pesticides Threaten Worse Environmental Harms Than DDTA looming and poorly regulated PFAS threat comes from these chemicals’ common use in pesticides on farms nationwideBy Nathan Donley & Kyla BennettWhen the U.S. Environmental Protection Agency ended most uses of the notorious pesticide DDT back in 1972, it wasn’t just because of the poison’s then suspected links to cancer and serious reproductive effects in humans. Evidence also suggested that the chemical would bioaccumulate in living things and persist in the environment for centuries, threatening the health of our children, our children’s children and beyond—a disturbing reality confirmed by recent research.Now, more than 50 years later, a growing body of research reveals the EPA is failing to fully address a similar, and potentially even greater, multigenerational chemical threat: the skyrocketing presence of perfluoroalkyl and polyfluoroalkyl substances (PFAS), aptly dubbed “forever chemicals,” in millions of gallons of pesticide products that are widely used across the U.S. PFAS contain chemical bonds that are extremely hard to break, making them difficult to get rid of once they are released into the world. PFAS contamination has been documented in hundreds of species of wildlife from the far reaches of the Arctic to the tropics in the Pacific Ocean. Very low concentrations of many PFAS have been linked to certain cancers, delays in childhood development and immune system dysfunction in humans. Earlier this year the EPA set drinking water regulations for six PFAS, with permissible levels in the excruciatingly minuscule “parts per trillion” range.When PFAS are present in pesticide products, many of which are sprayed on food crops and run off into nearby waterways, people can be exposed by eating contaminated food and drinking contaminated water.In a newly published study, we and our colleagues from several environmental watchdog groups identified troubling gaps in the EPA’s pesticide approval process that have resulted in the agency failing to fully assess the harms from the growing number of these forever chemicals added to many pesticides. The implications of that glaring lapse could not be more dire. The gaps in pesticide safety oversight—including waiving immunotoxicity studies for pesticide active ingredients, not fully accounting for the partial transformation of pesticides into different chemicals over time and failing to assess the cumulative toxicity of PFAS pesticide use—must be rectified moving forward.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Around one billion pounds of pesticide products are used each year across hundreds of millions of acres of U.S. farmland, making pesticides some of the nation’s most widely distributed pollutants. Simply put, if the goal was to spread forever chemicals as broadly as possible across the nation, there would likely be no more efficient way of doing so than putting them in pesticides.Our study found that 14 percent of all conventional active ingredients in pesticides are PFAS. Worse yet, the long-lived chemicals comprise 30 percent of pesticide active ingredients approved in just the past 10 years, meaning that pesticide contamination with PFAS is trending upward and will likely increase in the coming years.Although PFAS are known to leach from plastic storage containers into pesticides, contamination is more often the result of pesticide ingredients that are forever chemicals in their own right. PFAS pesticide ingredients and their “degradates”—what they turn into after partially breaking down—can stick around for decades or centuries and are incredibly potent. But the more potent and persistent the poison, the more likely it is to cause collateral damage.The trend is clear: pesticide manufacturers are increasingly in the business of making “forever pesticides.” According to estimates by the U.S. Geological Survey, the nation annually uses 23 million to 35 million pounds of pesticide ingredients that are PFAS.Yet what happens to those increasing loads of forever chemicals once they are sprayed on fields is not well understood. The little we do know is extremely troubling: although only about 20 percent of PFAS pesticides have been monitored in U.S. waterways, federal regulators have found nearly all of them in rivers and streams across the nation.The increasing “PFASification” of pesticides and the resulting environmental contamination are partly the result of regulations that seek to mitigate immediate toxicity concerns without fully accounting for the length of time a chemical will persist in the environment or for the effects of its degradates.Many researchers now believe that beyond a substance’s overt toxicities, its persistence alone should be a basis for its regulation, because any release of the substance into the environment will likely be irreversible. And as our understanding of PFAS toxicity grows over time, we have found these chemicals are often more harmful than previously thought.Right now, with summer coming to an end in the U.S., many farmers have already applied pesticides to try to suppress weeds, insects or fungi. That means tens of millions of pounds of forever chemicals were added to the environment this year alone and will remain there, in one form or another, for the birth of your grandchildren’s grandchildren and generations thereafter.It’s hard to imagine a more frightening indictment of the chemical-intensive agriculture that has been allowed to evolve in this country. But farmers are not the problem here. By not accounting for effects that will be realized decades or even centuries from now, EPA regulators are enabling this type of harmful agriculture.The only reason the EPA was able to ban incredibly persistent chemicals such as DDT and PCBs in the 1970s was because the agency acknowledged their long-term harm to society and the environment and faced, full-on, the difficult task of navigating the political challenges inherent in banning any widely used pesticide product.The agency tasked with the job of protecting our health and the environment must pivot and fully embrace its duty to reverse the fast-emerging threat posed by PFAS.If the EPA fails to face this challenge, it will be responsible for burdening generations to come with increases in deadly, chronic diseases and toxic cleanup responsibilities that will, quite literally, last forever.This is an opinion and analysis article, and the views expressed by the author or authors are not necessarily those of Scientific American.

Girls may be starting puberty earlier due to chemical exposure: Study

Girls exposed to certain chemicals that are common ingredients in household products may be starting puberty comparatively early, a new study has found. Substances of particular concern include musk ambrette — a fragrance used in some detergents, perfumes and personal care products — and a group of medications called cholinergic agonists, according to the study, published on Tuesday in Endocrinology. These chemicals are all known as "hormone-disrupting" or "endocrine-disrupting" compounds, due to their tendency to block or interfere with hormone function in the body's endocrine system. To draw their conclusions, National Institutes of Health (NIH) researchers performed an initial screening of 10,000 environmental compounds and then studied the activities of select substances using lines of both rodent and human brain cells that control reproductive functions. "Our team identified several substances that may contribute to early puberty in girls,” co-lead author Natalie Shaw, of the NIH's National Institute of Environmental Health Sciences, said in a statement. These compounds, Shaw and her colleagues found, were able to trigger certain receptors — proteins that bind to cell membranes and respond to stimuli — that play a key role in the puberty process. The proteins of interest, called gonadotropin-releasing hormone receptor and the kisspeptin receptor, are located in the hypothalamus, the section of the brain that regulates hormones and related bodily functions. The ability of compounds like musk ambrette to stimulate those receptors, Shaw explained, increases "the possibility that exposure may prematurely activate the reproductive access in children." Musk ambrette raised particular concern among the researchers due to its presence in personal care products. In addition, some rat studies have shown that it can cross the blood-brain barrier. Children are less likely to come into contact with the cholinergic agonist medications in their daily lives, the scientists noted. While Canadian and European regulators have already restricted musk ambrette use and the U.S. Food and Drug Administration removed the compound from its "generally recognized as safe" list, the compound remains widely available.  “Out of an abundance of caution, it is important for parents to only use personal care products for their children that are federally regulated,” Shaw said.
