Some States Are Banning Forever Chemicals. Now Industry Is Fighting Back.

Thursday, April 10, 2025

This story was originally published by WIRED and is reproduced here as part of the Climate Desk collaboration. In 2021, James Kenney and his husband were at a big box store buying a piece of furniture when the sales associate asked if they’d like to add fabric protectant. Kenney, the cabinet secretary of New Mexico’s Environment Department, asked to see the product data sheet. Both he and his husband were shocked to see forever chemicals listed as ingredients in the protectant. “I think about your normal, everyday New Mexican who is trying to get by, make their furniture last a little longer, and they think, ‘Oh, it’s safe, great!’ It’s not safe,” he says. “It just so happens that they tried to sell it to the environment secretary.” Last week, the New Mexico legislature passed a pair of bills that Kenney hopes will help protect consumers in his state. If signed by the governor, the legislation would eventually ban consumer products that have added PFAS—per- and polyfluorinated alkyl substances, known colloquially as “forever chemicals” because of their persistence in the environment—from being sold in New Mexico. As health and environmental concerns about forever chemicals mount nationally, New Mexico joins a small but growing number of states that are moving to limit—and, in some cases, ban—PFAS in consumer products. New Mexico is now the third state to pass a PFAS ban through the legislature. Ten other states have bans or limits on added PFAS in certain consumer products, including cookware, carpet, apparel, and cosmetics. This year, at least 29 states—a record number—have PFAS-related bills before state legislatures, according to an analysis of bills by Safer States, a network of state-based advocacy organizations working on issues around potentially unsafe chemicals. The chemical and consumer products industries have taken notice of this new wave of regulations and are mounting a counterattack, lobbying state legislatures to advocate for the safety of their products—and, in one case, suing to prevent the laws from taking effect. Some of the key exemptions made in New Mexico highlight some of the big fights that industries are hoping they’ll win in statehouses across the country: fights they are already taking to a newly industry-friendly US Environmental Protection Agency. PFAS is not just one chemical but a class of thousands. The first PFAS were developed in the 1930s; thanks to their nonstick properties and unique durability, their popularity grew in industrial and consumer uses in the postwar era. The chemicals were soon omnipresent in American lives, coating cookware, preventing furniture and carpets from staining, and acting as a surfactant in firefighting foam. “Fluoropolymers are PFAS. PFAS plastics are PFAS. They are dangerous at every stage of their life.” In 1999, a man in West Virginia filed a lawsuit against US chemical giant DuPont alleging that pollution from its factory was killing his cattle. The lawsuit revealed that DuPont had concealed evidence of PFAS’s negative health effects on workers from the government for decades. In the years since, the chemical industry has paid out billions in settlement fees around PFAS lawsuits: In 2024, the American multinational 3M agreed to pay between $10 billion and $12.5 billion to US public water systems that had detected PFAS in their water supplies to pay for remediation and future testing, though the company did not admit liability. (DuPont and its separate chemical company Chemours continue to deny any wrongdoing in lawsuits involving them, including the original West Virginia suit.) As the moniker “forever chemicals” suggests, mounting research has shown that PFAS accumulate in the environment and in our bodies and can be responsible for a number of health problems, from high cholesterol to reproductive issues and cancer. EPA figures released earlier this year show that almost half of the US population is currently exposed to PFAS in their drinking water. Nearly all Americans, meanwhile, have at least one type of PFAS in their blood. For a class of chemicals with such terrifying properties, there’s been surprisingly little regulation of PFAS at the federal level. One of the most-studied PFAS chemicals, PFOA, began to be phased out in the US in the early 2000s, with major companies eliminating the chemical and related compounds under EPA guidance by 2015. The chemical industry and manufacturers say that the replacements they have found for the most dangerous chemicals are safe. But the federal government, as a whole, has lagged behind the science when it comes to regulations: The EPA only set official drinking water limits for six types of PFAS in 2024. In lieu of federal guidance, states have started taking action. In 2021, Maine, which identified an epidemic of PFAS pollution on its farms in 2016, passed the first-ever law banning the sale of consumer products with PFAS. Minnesota followed suit in 2023. “The cookware industry has historically not really engaged in advocacy, whether it’s advocacy or regulatory,” says Steve Burns, a lobbyist who represents the industry. But laws against PFAS in consumer products—particularly a bill in California, which required cookware manufacturers to disclose to consumers if they use any PFAS chemicals in their products—were a “wakeup call” for the industry. Burns is president of the Cookware Sustainability Alliance, a 501(c)(6) formed in 2024 by two major companies in the cookware industry. He and his colleagues have had a busy year, testifying in 10 statehouses across the country against PFAS restrictions or bans (and, in some cases, in favor of new laws that would exempt their products from existing bans). In February, the CSA was one of more than 40 industry groups and manufacturers to sign a letter to New Mexico lawmakers opposing its PFAS ban when it was first introduced. The CSA also filed a suit against the state of Minnesota in January, alleging that its PFAS ban is unconstitutional. Its work has paid off. Unlike the Maine or Minnesota laws, the New Mexico bill specifically exempts fluoropolymers, a key ingredient in nonstick cookware and a type of PFAS chemical, from the coming bans. The industry has also seen success overseas: France excluded kitchenware from its recent PFAS ban following a lobbying push by Cookware Sustainability Alliance member Groupe SEB. (The CSA operates only in the US and was not involved in that effort.) A redefinition of PFAS by the federal government could “have a chilling effect on state legislation.” “As an industry, we do believe that if we’re able to make our case, we’re able to have a conversation, present the science and all the independent studies we have, most times people will say well, you make a good point,” Burns says. “This is a different chemistry.” It’s not just the cookware industry making this argument. Erich Shea, the director of product communications at the American Chemistry Council, told WIRED in an email that the group supports New Mexico’s fluoropolymer exclusion and that it will “allow New Mexico to avoid the headaches experienced by decisionmakers in other states.” The FDA has authorized nonstick cookware for human use since the 1960s. Some research—including one peer-reviewed study conducted by the American Chemistry Council’s Performance Fluoropolymer Partnership, whose members include 3M and Chemours, has found that fluoropolymers are safe to consume and less harmful than other types of PFAS. Separate research has called their safety into question. However, the production of fluoropolymers for use in nonstick cookware and other products has historically released harmful PFAS into the environment. And while major US manufacturers have phased out PFOA in their production chain, other factories overseas still use the chemical in making fluoropolymers. The debate over fluoropolymers’ inclusion in state bans is part of a larger argument made by industry and business groups: that states are defining PFAS chemicals too broadly, opening the door to overregulation of safe products. A position paper from the Cookware Sustainability Alliance provided to WIRED lambasts the “indiscriminate definition of PFAS” in many states with recent bans or restrictions. “Our argument is that fluoropolymers are very different from PFAS chemicals of concern,” Burns says. Some advocates disagree. The exemption of fluoropolymers from New Mexico’s ban, along with a host of other industry-specific exemptions in the bill, means that the legislation “is not going to meet the stated intentions of what the bill’s sponsors want it to do,” says Gretchen Salter, the policy director at Safer States. Advocates like Salter have concerns around the use of forever chemicals in the production of fluoropolymers as well as their durability throughout their life cycles. “Fluoropolymers are PFAS. PFAS plastics are PFAS. They are dangerous at every stage of their life, from production to use to disposal,” she claims. Kenney acknowledges that the fluoropolymer exemption has garnered a “little bit of criticism.” But he says that this bill is meant to be a starting point. “We’re not trying to demonize PFAS—it’s in a lot of things that we rightfully still use—but we are trying to gauge the risk,” he says. “We don’t expect this to be a one and done. We expect science to grow and the exemptions to change.” With a newly industry-friendly set of regulators in DC, industry groups are looking for wins at the federal level too. In February, an organization of chemical manufacturers and business groups, including the American Chemistry Council and the Cookware Sustainability Alliance, sent a letter to the EPA outlining suggested “principles and policy recommendations” around PFAS. The group emphasized the need to “recognize that PFAS are a broad class of chemistries with very diverse and necessary properties” and recommended the agency adopt a government-wide definition of PFAS based on West Virginia and Delaware’s definitions. Both of those states have a much more conservative definition of what defines PFAS than dozens of other states, including Maine, New Mexico, and Minnesota. A federal definition like this could “have a chilling effect on state legislation going forward,” said Melanie Benesh, the vice president of government affairs at the Environmental Working Group, an environmental activist organization. “There would be this federal position that the chemical industry could point to, which might be convincing to some state legislators to say, well, this is what the federal government has said is a definition of PFAS. As you start excluding PFAS from the class, you really limit what PFAS are covered by consumer product bans.” Shea, of the American Chemistry Council, told WIRED that the group believes “that the federal regulatory approach is preferable to a patchwork of different and potentially conflicting state approaches.” States with bans face a monumental task in truly getting PFAS out of consumers’ lives. Vendors in Minnesota have been left with expensive inventory that they can no longer sell; Maine’s law, one of the most aggressive, makes exemptions for “currently unavoidable use” of PFAS, including in semiconductors, lab equipment, and medical devices. PFAS are used in so many of the products in our lives that it’s almost unfathomable to think of phasing them out altogether, as soon as possible. For advocates like Salter, it’s a change worth making. “There might be essential uses for PFAS right now,” she says. “But we want to spur the search for safer alternatives, because we don’t want to give a pass to chemicals that are harming human health. By exempting them altogether, you are completely removing that incentive.”

In East Palestine Derailment Trial, Railroad and Chemical Maker Agree on Who Pays Residents

Norfolk Southern reached an agreement with one of the two companies it has been trying to force to help pay for the $600 million class-action settlement it agreed to over its disastrous 2023 train derailment near the Ohio-Pennsylvania border and the toxic chemicals that were released and burned

Norfolk Southern reached an agreement with one of two companies about how much each side will help pay for a $600 million class-action settlement, which the railroad agreed to after the disastrous 2023 Ohio train derailment and toxic chemicals that were released and burned.This lawsuit doesn’t change anything about how much money people will receive from the settlement or any payments to the village of East Palestine or anyone else — those are all established in various settlement agreements. This case only affects which companies have to write the checks to pay for the class-action settlement, which is separate from the cost of the massive environmental cleanup.The railroad and OxyVinyls, the chemical company that made the vinyl chloride that was released and burned after the derailment, announced the settlement Thursday in the midst of the ongoing trial over who should pay people affected by the derailment in East Palestine, Ohio.The two companies didn't disclose any details of the agreement in their brief statement.The third company involved in the lawsuit, GATX, which owned the railcar that caused the derailment, declined to comment on the settlement. The case is expected to go to the jury next week in a trial that began late last month.Residents are still waiting to receive most of the money from the settlement because of pending appeals, although some payments have started to go out.After the train derailed in East Palestine, an assortment of chemicals spilled and caught fire. Then three days later, officials blew open five tank cars filled with vinyl chloride because they feared those cars might explode, generating a massive black plume of smoke that spread over the area and forced evacuations. The National Transportation Safety Board confirmed in its investigation that the vent-and-burn operation was unnecessary because the tank cars were starting to cool off and the railroad failed to listen to the advice from OxyVinyls’ experts or share their opinions with the officials who made the decision.But during the trial, Norfolk Southern raised questions about conflicting information that OxyVinyls' representatives on scene and at headquarters provided as officials were deciding whether to release and burn the vinyl chloride.Norfolk Southern has said all along that it believes OxyVinyls should help pay because the railroad says the chemical manufacturer provided inconsistent and inaccurate information about its vinyl chloride before officials decided to burn it.Last year, Norfolk Southern lost a similar lawsuit when it tried to force GATX and OxyVinyls to help pay for the environmental cleanup after the derailment, which has cost the Atlanta-based railroad more than $1 billion. It made similar arguments in this trial to get help paying for the class-action settlement.Copyright 2025 The Associated Press. All rights reserved.

NASA Rover Finds Fresh Evidence of the Warm and Wet Past of Mars

WASHINGTON (Reuters) -A mineral called siderite found abundantly in rock drilled by a NASA rover on the surface of Mars is providing fresh evidence of the planet's warmer and wetter ancient past when it boasted substantial bodies of water and potentially harbored life.The Curiosity rover, which landed on Mars in 2012 to explore whether Earth's planetary neighbor was ever able to support microbial life, found the mineral in rock samples drilled at three locations in 2022 and 2023 inside Gale crater, a large impact basin with a mountain in the middle.Siderite is an iron carbonate mineral. Its presence in sedimentary rocks formed billions of years ago offers evidence that Mars once had a dense atmosphere rich in carbon dioxide, a gas that would have warmed the planet through the greenhouse effect to the point that it could sustain bodies of liquid water on its surface.There are features on the Martian landscape that many scientists have interpreted as signs that liquid water once flowed across its surface, with potential oceans, lakes and rivers considered as possible habitats for past microbial life.Carbon dioxide is the main climate-regulating greenhouse gas on Earth, as it is on Mars and Venus. Its presence in the atmosphere traps heat from the sun, warming the climate.Until now, evidence indicating the Martian atmosphere previously was rich in carbon dioxide has been sparse. The hypothesis is that when the atmosphere - for reasons not fully understood - evolved from thick and rich in carbon dioxide to thin and starved of this gas, the carbon through geochemical processes became entombed in rocks in the planet's crust as a carbonate mineral.The samples obtained by Curiosity, which drills 1.2 to 1.6 inches (3-4 centimeters) down into rock to study its chemical and mineral composition, lend weight to this notion. The samples contained up to 10.5% siderite by weight, as determined by an instrument onboard the car-sized, six-wheeled rover."One of the longstanding mysteries in the study of Martian planetary evolution and habitability is: if large amounts of carbon dioxide were required to warm the planet and stabilize liquid water, why are there so few detections of carbonate minerals on the Martian surface?" said University of Calgary geochemist Benjamin Tutolo, a participating scientist on NASA's Mars Science Laboratory Curiosity rover team and lead author of the study published on Thursday in the journal Science."Models predict that carbonate minerals should be widespread. But, to date, rover-based investigations and satellite-based orbital surveys of the Martian surface had found little evidence of their presence," Tutolo added.Because rock similar to that sampled by the rover has been identified globally on Mars, the researchers suspect it too contains an abundance of carbonate minerals and may hold a substantial portion of the carbon dioxide that once warmed Mars.The Gale crater sedimentary rocks - sandstones and mudstones - are thought to have been deposited around 3.5 billion years ago, when this was the site of a lake and before the Martian climate underwent a dramatic change."The shift of Mars' surface from more habitable in the past, to apparently sterile today, is the largest-known environmental catastrophe," said planetary scientist and study co-author Edwin Kite of the University of Chicago and Astera Institute."We do not know the cause of this change, but Mars has a very thin carbon dioxide atmosphere today, and there is evidence that the atmosphere was thicker in the past. This puts a premium on understanding where the carbon went, so discovering a major unsuspected deposit of carbon-rich materials is an important new clue," Kite added.The rover's findings offer insight into the carbon cycle on ancient Mars.On Earth, volcanoes spew carbon dioxide into the atmosphere, and the gas is absorbed by surface waters - mainly the ocean - and combines with elements such as calcium to form limestone rock. Through the geological process called plate tectonics, this rock is reheated and the carbon is ultimately released again into the atmosphere through volcanism. Mars, however, lacks plate tectonics."The important feature of the ancient Martian carbon cycle that we outline in this study is that it was imbalanced. In other words, substantially more carbon dioxide seems to have been sequestered into the rocks than was subsequently released back into the atmosphere," Tutolo said."Models of Martian climate evolution can now incorporate our new analyses, and in turn, help to refine the role of this imbalanced carbon cycle in maintaining, and ultimately losing, habitability over Mars' planetary history," Tutolo added.(Reporting by Will Dunham, Editing by Rosalba O'Brien)Copyright 2025 Thomson Reuters.

Salmon Are Being Exposed to Our Anti-Anxiety Medication, and It's Making Them Take More Risks, Study Suggests

Atlantic salmon exposed to a common anti-anxiety drug migrate faster, according to new research. That's not necessarily a good thing

Salmon Are Being Exposed to Our Anti-Anxiety Medication, and It’s Making Them Take More Risks, Study Suggests Atlantic salmon exposed to a common anti-anxiety drug migrate faster, according to new research. That’s not necessarily a good thing Researchers Daniel Cerveny and Marcus Michelangeli collecting salmon from the Dal River in Sweden. Michael Bertram Humans take a lot of medication, and small doses of those drugs—including antibiotics, antidepressants, birth control and more—find their way in the environment through wastewater, even after it’s treated. Nearly 1,000 different pharmaceuticals have been detected in waterways all over the world, even in Antarctica. Now, a new study sheds light on how these drugs affect wildlife behavior. “Pharmaceutical pollution, or chemical pollution in general, is really this invisible agent of global change,” says Jack Brand, the study’s lead author and an environmental researcher at the Swedish University of Agricultural Sciences, to Benji Jones at Vox. “It’s probably posing a greater risk than at least what the public acknowledges. This is a potentially significant threat to our aquatic wildlife.” To better understand this risk, Brand and his team gave young Atlantic salmon the drug clobazam—a common anti-anxiety and sleep medication—in doses that might mirror what they’re exposed to in the wild. The team used tracking tags to monitor how the medication affected the fish’s 17-mile migration from the Dal River in Sweden to the Baltic Sea. The salmon that were given clobazam were more likely to reach the sea than the untreated fish. They also quickly passed through two major hydropower dams that often slow other fish down. The new findings were published in the journal Science last week. Scientists say the drugged salmon might have migrated differently because of an increased willingness to take risks. “It’s interesting to see how one problem impacts how they deal with another problem,” says Olivia Simmons, a salmon ecologist at the Norwegian Institute for Nature Research who was not involved in the study, to Rebecca Dzombak at the New York Times. “These bolder fish could just be going faster because they’re less inhibited.” But going faster isn’t necessarily a good thing for the salmon. “It’s important to realize that any change to the natural behavior and ecology of a species is expected to have broader negative consequences, both for that species and the surrounding wildlife community,” explains study co-author Marcus Michelangeli, a behavioral ecologist at Griffith University in Australia, in a statement. Brand tells Jonathan Lambert at NPR that the fish exposed to clobazam may be more risk-prone and solitary, “and therefore just sort of beelining it through the dams rather than waiting around for their salmon friends.” A dam in Älvkarleby, Sweden, which is one of the obstacles that salmon in the Dal River must navigate on their migration. Rebecca Forsberg The researchers also took their study into the lab to better understand the impact of the drugs on the salmon, and the fish displayed other signs of solitary behavior. Clobazam appeared to change the way the fish interact with each other, making them less likely to school in groups—even when a predatory northern pike swam nearby. That independence could make them more vulnerable to being eaten. “It’s like playing poker,” adds Giovanni Polverino, a behavioral ecologist at the University of Tuscia in Italy who was not involved in the study, to the New York Times. “The more risks you take, the more chances you have to lose everything,” he adds. “In this case, the fish’s life.” Still, there’s hope on the horizon for the world’s fish, Michelangeli notes in the statement. Wastewater treatment options are getting better at reducing pharmaceutical contamination, and researchers are also working on making drugs that degrade more quickly. “By designing drugs that break down more rapidly or become less harmful after use, we can significantly mitigate the environmental impact of pharmaceutical pollution in the future,” he says.

Black Residents Get Most of the Pollution but Few of the Jobs From Chemical Industry, Study Finds

A new study led by Tulane University has revealed stark racial disparities across the U.S.’s petrochemical workforce

Residents of the mostly Black communities sandwiched between chemical plants along the lower Mississippi River have long said they get most of the pollution but few of the jobs produced by the region’s vast petrochemical industry. A new study led by Tulane University backs up that view, revealing stark racial disparities across the U.S.’s petrochemical workforce. Inequity was especially pronounced in Louisiana, where people of color were underrepresented in both high- and low-paying jobs at chemical plants and refineries. “It was really surprising how consistently people of color didn’t get their fair share of jobs in the petrochemical industry,” said Kimberly Terrell, a research scientist with the Tulane Environmental Law Clinic. “No matter how you slice or dice the data by states, metro areas or parishes, the data’s consistent.”The Tulane study’s findings match what Cancer Alley residents have suspected for decades, said Joy Banner, co-founder of the Descendants Project, a nonprofit that advocates for Black communities in the parishes between New Orleans and Baton Rouge. “You hear it a lot – that Black people are not getting the jobs,” she said. “But to have the numbers so well documented, and to see just how glaring they are – that was surprising.”People of color were underrepresented in all of the highest-paying jobs among the 30 states with a large petrochemical industry presence, but Louisiana and Texas had “the most extreme disparities,” according to the study, which was published in the journal Ecological Economics. While several states had poor representation on the upper pay scale, people of color were typically overrepresented in the lower earnings tiers. In Texas, nearly 60% of the working-age population is non-white, but people of color hold 39% of higher-paying positions and 57% of lower-paying jobs in the chemical industry. Louisiana was the only state in which people of color are underrepresented in both pay categories. People who aren’t white make up 41% of the working-age population but occupy just 21% of higher-paying jobs and about 33% of lower-paid jobs. The study relied on data from the U.S. Census Bureau, Equal Employment Opportunity Commission, Bureau of Labor Statistics and Louisiana Economic Development.The chemical industry disputed the study’s findings. “We recognize the importance of examining equity in employment, however, this study offers an incomplete and misleading portrayal of our industry and its contributions,” David Cresson, president and CEO of the Louisiana Chemical Association, said in a statement. Cresson pointed to several industry-supported workforce development programs, scholarships and science camps aimed at “closing the training gap in Louisiana.”But the study indicates education and training levels aren’t at the root of underrepresentation among states or metro areas. Louisiana’s education gap was modest, with college attainment at 30% for white residents and 20% for people of color. In places like Lake Charles and St. John the Baptist Parish, where petrochemical jobs are common, the gap was minimal — five percentage points or less.The industry’s investments in education are “just public relations spin,” Banner said. “The amount of money they’re investing in schools and various programs pales in comparison to how much they’re profiting in our communities,” she said. “We sacrifice so much and get so little in return.”Louisiana is also getting little from generous tax breaks aimed at boosting employment, the study found. The state’s Industrial Tax Exemption Program has granted 80% to 100% property tax exemptions to companies that promise to create new jobs. For each job created in Cameron Parish, where large natural gas ports have been built in recent years, companies were exempted from almost $590,000 in local taxes. In St. John, each job equated to about $1 million in uncollected tax revenue.“This tradeoff of pollution in exchange for jobs was never an equal trade,” said Gianna St. Julien, one of the study’s authors. “But this deal is even worse when the overwhelming majority of these companies’ property taxes are not being poured back into these struggling communities.” This story was originally published by Verite News and distributed through a partnership with The Associated Press.Copyright 2025 The Associated Press.

Plastics may disrupt the body’s clock, raise risk of chronic disease, study finds

This article was originally published by U.S. Right To Know and is republished here with permission under a Creative Commons license.Chemicals found in common food packaging plastics like cling film and snack pouches may interfere with the body’s natural 24-hour sleep-wake cycle, increasing the risk of sleep disorders, diabetes, immune problems, and even cancer, new research shows. Published this month in Environment International, the study from the Norwegian University of Science and Technology is the first to show that everyday polyurethane (PUR) and polyvinyl chloride (PVC) plastics contain compounds that can disrupt the body’s internal clock (circadian rhythm) by quickly interfering with a specific cell signal (A1R) linked to sleep and light. Unlike previous research that focused on slow, hormone-related effects, this study reveals a faster, direct impact on key “clock genes” through a different kind of biological pathway. That means plastic chemicals may contribute to serious health problems like diabetes or cancers in more ways than scientists currently know, the researchers say.“All of our cells follow a circadian rhythm, and the chemicals found in plastics can change that rhythm. Importantly, these chemicals are making rapid changes in our cells that can turn into sustained changes over longer periods of time,” says lead author Molly Young McPartland. “Circadian rhythms are one outcome affected by the biological pathway initiated by A1R, but not the only one. This work really demonstrates how much we still have to learn about exactly how plastic chemicals can affect our cells.”Plastic chemicals may throw our body clock off balancePlastic compounds in everything from toys to personal care products can harm health when they leach into the environment and human body. PVC and PUR are among the most common types of plastics, found nearly everywhere in our homes, schools, and offices.For example:PVC is used in food packaging like clear trays, blister packs (e.g., for gum), and shrink wraps, especially for meats and produce. PUR is typically found in multilayer flexible packaging as an adhesive or coating—such as in snack pouches and foil-lined food wrappers—and sometimes in foam inserts for protecting delicate items like chocolates.Our body’s 24-hour internal clock controls sleep, metabolism, immune function, cell repair, and other essential functions. The circadian rhythm is influenced by environmental cues like sunlight, temperature, and oxygen, as well as internal signals such as hormones and metabolism.When the rhythm is off balance, however, it has been shown to contribute to the development of serious long-term health problems like diabetes, cancer, or heart disease.Part of that may be due to the fact that plastic chemicals have long been known to release endocrine-disrupting chemicals (EDCs)—such as phthalates and bisphenols—that can interfere with the body’s hormone systems. Now, this study highlights a new potential impact disrupting the timing of two key genes that help control the body’s internal clock.The delays are less powerful than what happens after caffeine consumption or bedtime exposure to light, the researchers note. Many factors also affect how sensitive an individual may be to both internal and external signals that control the body clock.However, long-term, frequent exposure to plastic chemicals—especially through food packaging—makes the potential impact more concerning, the researchers say. When repeated daily and combined with other environmental disruptions, exposure could shift the timing of key body processes that contribute to negative health impacts over time, they say. Caffeine wakes us up, plastics do the oppositeFor this study, the researchers tested chemical mixtures extracted from polyurethane and polyvinyl chloride on U20S lab cells. These cells are derived from a human bone cancer (osteosarcoma) cell line that is often used to study how biological clocks work at the cellular level.What they found involves a type of protein called the adenosine A1 receptor (A1R), which is found on the surface of cells throughout the body, especially in the brain, the researchers say.A1R has a well-established link to the sleep-wake cycle and uses the same pathways in the body that respond to light. In humans, caffeine blocks A1R to keep us awake—but plastic chemicals appear to quickly activate it, the researchers found.When A1R is activated, it lowers levels of a molecule that plays a key role in keeping the circadian clock running smoothly. This, in turn, delays two “clock genes,” which are essential for maintaining the body’s daily rhythms.The study was done in vitro (outside the body, in a lab), so the results might not apply directly to humans. However, the researchers say the findings “provide strong evidence that the chemicals in PUR and PVC plastics disrupt the molecular clock” because the effects changed with the dose and could be reversed.The researchers measured these “clock genes” every 4 hours over two days and found the activity of these genes was delayed by 9 to 17 minutes. When they blocked A1R using a drug, the delays disappeared.A call for safer plastics, tighter controlsThe study notes that large gaps still exist in scientists’ understanding of how plastic chemicals affect the body on a molecular level. Only a handful of chemicals—such as acrylamide, tolylfluanid, and some phthalates, which are used to make plastics softer and more durable—have been shown to disrupt core clock genes in mammals, but their mechanisms remain unclear.More studies are needed, along with calls for safer plastics and stricter regulation of plastic chemicals, the researchers say.“This study adds to the increasing body of evidence that plastics contain compounds causing a wide range of toxic effects,” they say. “A fundamental shift in the design and production of plastics is essential to ensure their safety. Reducing both the number and the hazards of chemicals in plastics can decrease exposures and lessen their impacts on public health.”
