Sign up for The Brief, The Texas Tribune’s daily newsletter that keeps readers up to speed on the most essential Texas news. A booming petrochemical buildout on the Gulf Coast has drawn billions of dollars in public subsidies from state tax abatement programs despite regular violations of pollution permits, according to a new report released Thursday. The Environmental Integrity Project, an environmental nonprofit based in Texas and Washington, D.C., compiled data on all U.S. plastics projects built, expanded or proposed since 2012, almost all of them along the Gulf Coast. The report identified 50 plastics complexes built or expanded in the last 12 years, 33 of them in Texas, where they have drawn a total of $1.65 billion in property tax breaks through the state’s Chapter 313 program for energy and manufacturing companies, which the state legislature replaced last year with a new but similar program. That’s a tiny dent in Texas’ $250 billion annual tax revenue, but it’s just one visible slice of the total concessions corporations receive to do business in Texas, and it represents lost income that would have gone primarily to the state’s public schools, which are struggling with shortfalls in teachers and funding. Now, companies are proposing to build an additional 42 plastics plants, 24 of them in Texas, according to the 73-page EIP report, “Feeding the Plastics Industrial Complex.” “The industry is expanding rapidly, and more communities are being asked to consider public subsidies,” it said. “None of the state programs we examined require industries to follow the terms of their state pollution control permits.” While Texas hosts the most new plastics production, the most generous tax breaks come from neighboring Louisiana, among the nation’s poorest states, where three projects alone drew $6.5 billion in local discounts since 2013. All operating projects considered in the EIP report claimed a total of $9 billion in exchange for commitments to economic development and job growth. That money would have otherwise funded local schools and public services, said Alexandra Shaykevich, research manager at the Environmental Integrity Project. Instead, it’s given to highly profitable corporations that are often foreign-owned and likely would have located near the nation’s major oil and gas resources with-or-without local tax incentives, according to her group’s report. Most facilities reviewed by the EIP reported repeated violations of their pollution permits, Shaykevich said, but those violations never jeopardized their tax subsidies. “I think if companies can’t obey the law they shouldn't be rewarded with taxpayer money,” she said. “We would certainly advocate for making subsidies conditional on compliance.” The American Chemistry Council and the Texas Chemistry Council, which represent the plastics business, did not immediately respond to requests for comment. Texas Sen. Charles Schwertner, chair of the Senate Committee on Business and Commerce, said the state’s tax incentive program “bolsters economically distressed communities and enhances its competitive advantage in attracting vital industries.” “The program ensures that the Texas economic miracle continues to thrive by offering quality employment opportunities for Texans and investments in our communities,” Schwertner said. Gulf Coast Expansion  The recent growth in Gulf Coast petrochemicals, which include plastics, are a result of the ongoing boom in hydraulic fracturing upstream in the Eagle Ford Shale and Permian Basin of Texas. Pipelines carry oil and gas hundreds of miles to the coast, where refineries and chemical plants produce commercial products and load them onto ships for sale overseas. The United States . remains a world leader in petrochemical production and export thanks primarily to these industries, said Joe Powell, executive director of the Energy Transition Institute at the University of Houston. “We’ve got really good energy prices here on the Gulf Coast because of fracking,” he said. “That makes the U.S. Gulf Coast a really good investment opportunity, especially in petrochemicals.” Within plastics, he said, most recent growth has come from ethane crackers, facilities that turn natural gas into ethylene, which, according to the American Chemistry Council, can be made into polymers that are “used to manufacture fibers, bins, pails, crates, bottles, piping, food packaging films, trash liners, bags, wire and cable sheathing, insulation, surface coatings for paper and cardboard, and a wide variety of other products.” The U.S. is the top exporter of ethylene polymers, much of which go to China, the world’s top importer. Powell, a former chief scientist for Shell, the global energy company, said years of rapid expansions have brought a glut of ethylene to market and left the Gulf Coast overbuilt in the short term, which he called “typical of the chemical business.” But in the long term, robust demand for plastics is expected to rapidly grow. The Paris-based Organisation for Economic Co-operation and Development predicts global plastics demand will triple between 2019 and 2060. Much of that supply will come from Texas. High demand for plastics and other petrochemicals will support a growing share of fossil fuel production, said Tom Sanzillo, a director of financial analysis at the Institute for Energy Economics and Financial Analysis, as major sectors like transportation fuels and power generation shift to more sustainable forms of energy. Proposed Projects in Texas For its report, the EIP drew on public records, including permit applications and company announcements, to compile a list of plastics projects currently proposed. Their data shows a wave of new development still planned for the Texas coast, including seven new complexes and 20 expansions at existing complexes. For example, it said Formosa Plastics, a $460 billion Taiwanese company, has proposed to build a new vinyl chloride reactor, which produces material for PVC plastic, at its 2,500-acre Point Comfort complex on Lavaca Bay. (The company has quietly advanced other expansion plans lately, as well.) At neighboring Matagorda Bay, German petrochemical manufacturer Roehm plans to turn greenfields into a new plant to produce methyl methacrylate, a component of common construction plastics. In Corpus Christi, a joint Singaporean-Taiwanese-Mexican venture plans to build a new manufacturing complex for polyethylene terephthalate, a common plastic in disposable packaging, named “Project Jumbo.” The complex, proposed by the companies Indorama, Far Eastern New Century and Alpek, will also include a desalination plant to pull seawater from Nueces Bay. Near Houston, ExxonMobil plans three major expansions at its massive Baytown complex: a new cracking furnace, expansion of its polypropylene plant and a new hydrogen plant to power those and other units. The highest concentration of proposed new plastics complexes surrounds Port Arthur, a small city ringed in heavy industry that boasts some of the last available ship channel waterfront on the Gulf. There, Motiva Enterprises, which is owned by the government of Saudi Arabia, has proposed a new ethylene unit consisting of eight furnaces next to its existing Port Arthur refinery. Ethylene is produced by heating natural gas or petroleum to above 800 degrees Celsius, which produces a mixture of gases from which ethylene is separated. Texas-based companies Energy Transfer, Enterprise Products Partners and Chevron Philipps Chemical have also proposed new complexes of ethylene and polyethylene units in the area. “Our local government and our state government welcomes this activity, but the people who live in the shadows of the industry are the ones who continue to suffer,” said Hilton Kelley, 63, a community organizer from Port Arthur. “In most of these situations around the nation, you will find that it’s people of color.” Forty-three percent of Port Arthur residents are Black, more than three times the statewide average. Much of the city is in the 95th percentile nationally for both the volume of toxic air pollution released and resulting cancer risk, according to the U.S. Environmental Protection Agency. Credit: James Bruggers/Inside Climate News “We’re just like a dumping ground,” said Kelley. “A large number of my friends and relatives have died from cancer.” But despite the abundance of multibillion-dollar industries in Port Arthur, median household income is 37 percent less than Texas as a whole while its poverty rate is nearly double. State Tax Abatement Programs In its report, the EIP found at least two-thirds of the 50 recently completed plastics projects it reviewed nationally received tax abatements through state or local governments. Of the top four recipients, three were in Louisiana, drawing a combined $4.6 billion from the state’s Industrial Tax Exemption Program since 2013, and one was in Pennsylvania, a massive Shell ethylene plant in Beaver County outside Pittsburgh, which drew $1.65 billion from Pennsylvania’s Resource Manufacturing Tax Credit. All were owned, in part or in full, by corporations from Asia, Africa or Europe. The fifth top recipient was Dow Chemical’s Freeport chemical complex in Brazoria County, which received $393 million in operating discounts since 2013 through Texas’ Chapter 313 tax abatement program. Dow did not immediately respond to a request for comment. “It sounds like a lot of money. But in this game that some people would call interstate competition for growth and others would call corporate welfare, it’s not an overwhelming amount,” said Mike Kraten, director of accounting program initiatives at the University of Houston’s Bauer College of Business. “I think anyone would agree that this has become par for the course.” Chapter 313, one of many tax abatement programs in Texas, represents a small slice of the total incentives that companies may receive to invest here. The biggest concessions are typically custom-negotiated in private between company lobbyists and state or local governmental development offices, Kraten said. Chapter 313 drew criticism from both Republicans and Democrats in Texas. The conservative think tank Texas Public Policy Foundation called it“unnecessary and wasteful.”Texas doesn’t need to offer tax incentives, critics argued, because its oil and gas fields mean companies will locate here anyway. Last year, the Texas Legislature replaced the Chapter 313 program with a similar program called Chapter 403, which the think tank Every Texan called “better in some ways, worse in others.” According to Dick Lavine, a senior analyst at Every Texan, two 403 agreements have been signed to date. Meanwhile, the Texas comptroller’s office shows 872 tax abatement agreements still active under Chapter 313. Last year, an analysis by the Houston Chronicle showed those outstanding agreements will cost Texas taxpayers $31 billion in lost revenue over the next 30 years. Regular Violations of Pollution Permits  These subsidies are awarded irrespective of companies’ history of compliance with environmental law, the EIP report found.. Of the plastics plants it considered, 84 percent had self-reported violations of their pollution permits to state environmental regulators. “They seldom face penalties and never have their public subsidies revoked, no matter how frequent their environmental permit violation,” the report said. For example, it cited Gulf Coast Growth Ventures, a huge, new plastics plant outside Corpus Christi, jointly owned by the Saudi Basic Industries Corp. and ExxonMobil, the world’s largest private oil company, which posted a record $56 billion profit in 2022. Located in the town of Gregory, which is 90 percent Hispanic, the project secured in 2017 a $249 million tax break from the Gregory-Portland Independent School District for the period between 2022 and 2032. Then, between 2021 and 2022, the facility reported 10 unpermitted pollution releases totalling 560,802 pounds due to equipment failure, emergency flaring or unplanned shutdowns. During one incident in 2022, the glow of burning ground flares was visible from 20 miles away for days, according to the Corpus Christi Caller Times. The plant also incurred 63 violations from Texas’ environmental regulator in less than two years, according to the EIP report. “These include failure to comply with limits for pollutants such as nitrogen oxide and carbon monoxide, failure to properly sample and analyze discharges of stormwater from the site, and failing to properly operate and monitor its flares,” the report said. An ExxonMobil spokesperson, Lauren Knight, said Gulf Coast Growth Ventures has donated $20 million to the local community “including local enrichment projects, environmental preservation, STEM programs, city infrastructure and air monitoring.” Knight said air monitors installed in 2019 have shown no change in air quality since. “At all of our sites, our focus is on reducing emissions, improving air quality and protecting the environment. We maintain the highest standards for safety, health and environmental care and comply with all applicable laws and regulations,” Knight said. All of the top seven U.S. plastics plants that incurred legal penalties for Clean Air Act violations between 2020 and 2023 were in Texas, the report found. Brandy Deason, climate justice coordinator for the nonprofit Air Alliance Houston, which collaborated on the report, said public subsidies shouldn’t go to companies that harm public health beyond what their pollution permits allow. Before Air Alliance Houston, she worked at commercial laboratories in Louisiana and Texas that analyzed air samples from industrial operators for their reports to regulators. That’s where she realized what sorts of vapors wafted from refineries and chemical plants—things like benzene, butadiene and all manner of volatile organic compounds. “I saw the air pollution first hand. I ran it through the instruments. I did the reports,” she said. “I saw a lot of pollution.” What frustrates her most, she said, was the pointlessness of much of it. While many plastics are now used in construction and high-grade medical gear, much more goes to single-use packaging that wasn’t present in the world just a few decades ago. And, she said, campaigns by Air Alliance Houston and its allies to slow the pace of plastics expansions authorized by Texas regulators have been largely ineffective. “Even if the community speaks out, permits are almost never denied,” she said. “We’re constantly showing them the problems, we just get ignored and they get the permits.” Disclosure: Air Alliance Houston, Dow Chemical, Energy Transfer, Every Texan, Exxon Mobil Corporation, Texas Public Policy Foundation and University of Houston have been financial supporters of The Texas Tribune, a nonprofit, nonpartisan news organization that is funded in part by donations from members, foundations and corporate sponsors.

Gulf Coast Expansion 

The recent growth in Gulf Coast petrochemicals, which include plastics, are a result of the ongoing boom in hydraulic fracturing upstream in the Eagle Ford Shale and Permian Basin of Texas. Pipelines carry oil and gas hundreds of miles to the coast, where refineries and chemical plants produce commercial products and load them onto ships for sale overseas.

The United States . remains a world leader in petrochemical production and export thanks primarily to these industries, said Joe Powell, executive director of the Energy Transition Institute at the University of Houston.

“We’ve got really good energy prices here on the Gulf Coast because of fracking,” he said. “That makes the U.S. Gulf Coast a really good investment opportunity, especially in petrochemicals.”

Within plastics, he said, most recent growth has come from ethane crackers, facilities that turn natural gas into ethylene, which, according to the American Chemistry Council, can be made into polymers that are “used to manufacture fibers, bins, pails, crates, bottles, piping, food packaging films, trash liners, bags, wire and cable sheathing, insulation, surface coatings for paper and cardboard, and a wide variety of other products.”

The U.S. is the top exporter of ethylene polymers, much of which go to China, the world’s top importer.

Powell, a former chief scientist for Shell, the global energy company, said years of rapid expansions have brought a glut of ethylene to market and left the Gulf Coast overbuilt in the short term, which he called “typical of the chemical business.”

But in the long term, robust demand for plastics is expected to rapidly grow. The Paris-based Organisation for Economic Co-operation and Development predicts global plastics demand will triple between 2019 and 2060. Much of that supply will come from Texas.

Chemicals, forever: how do you fix a problem like PFAS?

In Australia, the taxpayer has footed the bill for the forever chemical clean-up so far. But this will have to change.

EdBelkin/ShutterstockA landmark legal settlement has once again focused our attention on the dangers of “forever chemicals”. This class of chemicals, technically known as per-and polyfluoroalkyl substances, or PFAS, are widely used to make nonstick or waterproof products. The problem is, the chemicals move easily around the environment, pollute groundwater and rivers, are often carcinogenic – and they don’t degrade. This month, one of the largest makers of these chemicals, 3M, had its offer of A$16 billion to clean up PFAS-contaminated waterways approved by a US court. It’s just the latest in a series of PFAS lawsuits across the United States. While increased attention is welcome, there’s no guarantee of success. Removing and destroying PFAS from wastewater streams across a single US state, Minnesota, would cost a minimum of $21 billion over 20 years. Globally, a recent report by the chemical safety nonprofit ChemSec found the costs of PFAS remediation alone amount to around $26 trillion per year – not including rising healthcare costs from exposure to PFAS, or damage to the environment. The 3M settlement is just the tip of the iceberg. The problem now is how to actually clean up these chemicals – and prevent further pollution. Remediation is expensive – and uncertain In Australia, contamination is worst in firefighter training grounds and on defence force bases, due to the long-term use of firefighting foams full of PFAS. The discovery of this contamination triggered a wave of lawsuits. The Department of Defence has since paid out more than $366 million in class action lawsuits. Defence has also assumed responsibility for managing, remediating and monitoring PFAS contamination on and around its bases. In 2021, the department began to actively set about remediation. Read more: Removing PFAS from public water systems will cost billions and take time – here are ways you can filter out harmful 'forever chemicals' at home That sounds promising – find the pollution and fix the problem. But the reality is much more complicated. A 2022 parliamentary inquiry described PFAS remediation as an emerging and experimental industry. This is correct. There’s a great deal of basic scientific research we have to do. This is not a simple problem. These chemicals seep into the soil and groundwater – and stay there. It’s hard to get them out. As a result, most remediation work at defence bases to date has been part of research and development, rather than a wide-scale permanent cleanup. To help, the defence department has brought in three major industry partners, including Emerging Compounds Treatment Technologies. We don’t know how they are doing the cleanup or if their methods work, as this information is not publicly accessible. The three companies have sought intellectual property protection to support their technological advantage in the growing PFAS remediation market. One of the companies, Venetia, told the parliamentary inquiry: [there] are still significant gaps in knowledge in keys areas such as human health toxicology, PFAS behaviour in the environment and remediation of PFAS in soil and water PFAS is a much bigger problem Significant PFAS contamination has now been reported in: – Melbourne’s West Gate Tunnel construction site. Soil contamination at the most polluted site is hundreds of times worse than a threshold set by the state’s environmental protection agency – Western Australian mines – WA waste management facilities – Southeast Queensland water reclamation plants – Perth’s public and private airports – Operating and closed landfills. The full extent of PFAS contamination in Australia is still emerging. Recent research has found Australia is one of several toxic hotspots for PFAS, relative to the rest of the world. Getting forever chemicals out of groundwater is going to be hard – but necessary. Mumemories/Shutterstock Worse, current monitoring practices are likely to be underestimating how much PFAS is lingering in the environment, given we usually only track a handful of these chemicals – out of more than 16,000. Experts have called for: improved understanding of the range of PFAS embodied in consumer and industrial products […] to assess the environmental burden and develop mitigation measures The more we look, the more alarming the picture appears. Emerging research has found PFAS in consumer products such as cosmetics, packaging, waterproofing, inks, pesticides, medical articles, polishes and paints, metal plating, pipes and cables, mechanical components, electronics, solar cells, textiles and carpets. The size and complexity of PFAS contamination suggests we are in for a very long and expensive process to begin cleaning it up – especially given we are still making and using these chemicals. Read more: Controversial ‘forever chemicals’ could be phased out in Australia under new restrictions. Here’s what you need to know How should we respond? To start addressing the problem, here are three important steps. 1. Introduce a “polluter pays” principle. The introduction of this concept is what forced 3M to pay up in the US. Australia has yet to follow suit, which is why the public has been footing the bill. If we introduce this legal principle, manufacturers will have to take responsibility. This would make it much less attractive for companies to make polluting products – and shift the burden from taxpayers to the companies responsible. Australia’s government is considering pursuing similar legal action against 3M. 2. Set PFAS contamination standards in line with other OECD countries, or better. Earlier this month, the US implemented the first legally enforceable national drinking water standards for five PFAS compounds and two PFAS mixtures. Australia’s current acceptable drinking water guidelines allow up to 140 times more PFAS in our water than these strict new US standards. In the US, these new standards are drawing new investment in remediation. 3. Take it seriously. For years, many of us thought all you had to do to avoid PFAS was not to buy nonstick pans. But these chemicals are now everywhere. They’re highly persistent and don’t leave our bodies easily. Every single person on the planet is now likely to have detectable levels of PFAS in their blood. Reducing this dangerous chemical load is going to take a lot of work to clean up existing hotspots, stop further production, and prevent recirculation of PFAS in recycled products or in our food. The 3M settlement is a good start. But it’s only a start. Tackling this problem is going to be hard, but necessary.

A chemical called 6PPD, which is added to rubber tires, is released when tires hit pavement. It reacts with ozone to become a different chemical, 6PPD-q, which can be extremely toxic — so much so that it has been linked to repeated fish kills in Washington state.

For decades, concerns about automobile pollution have focused on what comes out of the tailpipe. Now, researchers and regulators say, we need to pay more attention to toxic emissions from tires as vehicles roll down the road.At the top of the list of worries is a chemical called 6PPD, which is added to rubber tires to help them last longer. When tires wear on pavement, 6PPD is released. It reacts with ozone to become a different chemical, 6PPD-q, which can be extremely toxic — so much so that it has been linked to repeated fish kills in Washington state.The trouble with tires doesn’t stop there. Tires are made primarily of natural rubber and synthetic rubber, but they contain hundreds of other ingredients, often including steel and heavy metals such as copper, lead, cadmium, and zinc.As car tires wear, the rubber disappears in particles, both bits that can be seen with the naked eye and microparticles. Testing by a British company, Emissions Analytics, found that a car’s tires emit 1 trillion ultrafine particles per kilometer driven — from 5 to 9 pounds of rubber per internal combustion car per year.And what’s in those particles is a mystery, because tire ingredients are proprietary.“You’ve got a chemical cocktail in these tires that no one really understands and is kept highly confidential by the tire manufacturers,” said Nick Molden, CEO of Emissions Analytics. “We struggle to think of another consumer product that is so prevalent in the world and used by virtually everyone, where there is so little known of what is in them.”Regulators have only begun to address the toxic tire problem, though there has been some action on 6PPD.The chemical was identified by a team of researchers, led by scientists at Washington State University and the University of Washington, who were trying to determine why coho salmon returning to Seattle-area creeks to spawn were dying in large numbers.Working for the Washington Stormwater Center, the scientists tested some 2,000 substances to determine which one was causing the die-offs, and in 2020 they announced they’d found the culprit: 6PPD.The Yurok Tribe in Northern California, along with two other West Coast Native American tribes, have petitioned the Environmental Protection Agency to prohibit the chemical. The EPA said it is considering new rules governing the chemical. “We could not sit idle while 6PPD kills the fish that sustain us,” said Joseph L. James, chairman of the Yurok Tribe, in a statement. “This lethal toxin has no place in any salmon-bearing watershed.”California has begun taking steps to regulate the chemical, last year classifying tires containing it as a “priority product,” which requires manufacturers to search for and test substitutes.“6PPD plays a crucial role in the safety of tires on California’s roads and, currently, there are no widely available safer alternatives,” said Karl Palmer, a deputy director at the state’s Department of Toxic Substances Control. “For this reason, our framework is ideally suited for identifying alternatives to 6PPD that ensure the continued safety of tires on California’s roads while protecting California’s fish populations and the communities that rely on them.”The U.S. Tire Manufacturers Association says it has mobilized a consortium of 16 tire manufacturers to carry out an analysis of alternatives. Anne Forristall Luke, USTMA president and CEO, said it “will yield the most effective and exhaustive review possible of whether a safer alternative to 6PPD in tires currently exists.”Molden, however, said there is a catch. “If they don’t investigate, they aren’t allowed to sell in the state of California,” he said. “If they investigate and don’t find an alternative, they can go on selling. They don’t have to find a substitute. And today there is no alternative to 6PPD.”California is also studying a request by the California Stormwater Quality Association to classify tires containing zinc, a heavy metal, as a priority product, requiring manufacturers to search for an alternative. Zinc is used in the vulcanization process to increase the strength of the rubber.When it comes to tire particles, though, there hasn’t been any action, even as the problem worsens with the proliferation of electric cars. Because of their quicker acceleration and greater torque, electric vehicles wear out tires faster and emit an estimated 20% more tire particles than the average gas-powered car.A recent study in Southern California found tire and brake emissions in Anaheim accounted for 30% of PM2.5, a small-particulate air pollutant, while exhaust emissions accounted for 19%. Tests by Emissions Analytics have found that tires produce up to 2,000 times as much particle pollution by mass as tailpipes.These particles end up in water and air and are often ingested. Ultrafine particles, even smaller than PM2.5, are also emitted by tires and can be inhaled and travel directly to the brain. New research suggests tire microparticles should be classified as a pollutant of “high concern.”In a report issued last year, researchers at Imperial College London said the particles could affect the heart, lungs, and reproductive organs and cause cancer.People who live or work along roadways, often low-income, are exposed to more of the toxic substances.Tires are also a major source of microplastics. More than three-quarters of microplastics entering the ocean come from the synthetic rubber in tires, according to a report from the Pew Charitable Trusts and the British company Systemiq.And there are still a great many unknowns in tire emissions, which can be especially complex to analyze because heat and pressure can transform tire ingredients into other compounds.One outstanding research question is whether 6PPD-q affects people, and what health problems, if any, it could cause. A recent study published in Environmental Science & Technology Letters found high levels of the chemical in urine samples from a region of South China, with levels highest in pregnant women.The discovery of 6PPD-q, Molden said, has sparked fresh interest in the health and environmental impacts of tires, and he expects an abundance of new research in the coming years. “The jigsaw pieces are coming together,” he said. “But it’s a thousand-piece jigsaw, not a 200-piece jigsaw.”California Healthline is a service of the California Health Care Foundation produced by KFF Health News, an editorially independent program of the KFF.

Puzzling Scientists for Over 50 Years – A “Holy Grail” Chemical Mystery Has Been Solved

Researchers have solved a 50-year-old mystery about why organic matter in water resists degradation, finding that the oxidative dearomatization reaction transforms biomolecules into stable, diverse forms, significantly impacting global carbon cycles.A mystery that has puzzled the scientific community for over 50 years has finally been solved. A team from Linköping University, Sweden, and Helmholtz Munich have discovered that a certain type of chemical reaction can explain why organic matter found in rivers and lakes is so resistant to degradation. Their study has been published in the journal Nature.“This has been the holy grail within my field of research for over 50 years,” says Norbert Hertkorn, a scientist in analytical chemistry previously at Helmholtz Munich and currently at Linköping University.Let us take it from the beginning. When, for example, a leaf detaches from a tree and falls to the ground, it begins to break down immediately. Before the leaf decomposes, it consists of a few thousand distinct biomolecules; molecules that can be found in most living matter. The decomposition of the leaf occurs in several phases. Insects and microorganisms begin to consume it, while sunlight and humidity affect the leaf, causing further breakdown. Eventually, the molecules from the decomposed leaf are washed into rivers, lakes, and oceans.Chemical Transformation Mystery UnraveledHowever, at this point, the thousands of known biomolecules have been transformed into millions of very different-looking molecules with complex and typically unknown structures. This dramatic chemical transformation process has remained a mystery that has confounded researchers for over half a century, until now.David Bastviken, professor of environmental change at Linköping University, Sweden. Credit: Charlotte Perhammar“Now we can elucidate how a couple of thousand molecules in living matter can give rise to millions of different molecules that rapidly become very resistant to further degradation,” says Norbert Hertkorn.The team discovered that a specific type of reaction, known as oxidative dearomatization, is behind the mystery. Although this reaction has long been studied and applied extensively in pharmaceutical synthesis, its natural occurrence remained unexplored.In the study, the researchers showed that oxidative dearomatization changes the three-dimensional structure of some biomolecule components, which in turn can activate a cascade of subsequent and differentiated reactions, resulting in millions of diverse molecules.Study Findings and TechniquesScientists previously believed that the path to dissolved organic matter involved a slow process with many sequential reactions. However, the current study suggests that the transformation occurs relatively quickly.The team examined dissolved organic matter from four tributaries of the Amazon River and two lakes in Sweden. They employed a technique called nuclear magnetic resonance (NMR) to analyze the structure of millions of diverse molecules. Remarkably, regardless of the climate, the fundamental structure of the dissolved organic matter remained consistent.“Key to the findings was the unconventional use of NMR in ways allowing studies of the deep interior of large dissolved organic molecules – thereby mapping and quantifying the chemical surroundings around the carbon atoms,” explains Siyu Li, a scientist at the Helmholtz Zentrum and lead author of the study.In biomolecules, carbon atoms can be connected to four other atoms, most often to hydrogen or oxygen. However, to the team’s surprise, a very high fraction of the organic carbon atoms was not connected to any hydrogen but instead primarily to other carbon atoms. Particularly intriguing was the large number of carbon atoms bound specifically to three other carbons and one oxygen atom, a structure being very rare in biomolecules.According to David Bastviken, professor of environmental change at Linköping University, this renders the organic matter stable, allowing it to persist for a long time and preventing it from rapidly returning to the atmosphere as carbon dioxide or methane.“This discovery helps explain the substantial organic carbon sinks on our planet, which reduce the amount of carbon dioxide in the atmosphere,” says David Bastviken.Reference: “Dearomatization drives complexity generation in freshwater organic matter” by Siyu Li, Mourad Harir, David Bastviken, Philippe Schmitt-Kopplin, Michael Gonsior, Alex Enrich-Prast, Juliana Valle and Norbert Hertkorn, 24 April 2024, Nature.DOI: 10.1038/s41586-024-07210-9Funding: Alexander von Humboldt-Stiftung, Vetenskapsrådet, European Research Counci
