In the summer of 1982, seven heroin users were admitted to a California hospital paralyzed and mute. They were in their 20s, otherwise healthy — until a synthetic drug they had manufactured in makeshift labs left them frozen inside their own bodies. Doctors quickly discovered the cause: MPTP, a neurotoxic contaminant that had destroyed a small but critical part of the brain, the substantia nigra, which controls movement. The patients had developed symptoms of late-stage Parkinson’s, almost overnight. Until then, Parkinson’s was thought to be a disease of aging, its origins slow and mysterious. But here was proof that a single chemical could reproduce the same devastating outcome. And more disturbing still: MPTP turned out to be chemically similar to paraquat, a widely used weedkiller that, for decades, had been sprayed on farms across the United States and Europe. Parkinson’s disease has more than doubled globally over the past 20 years, and is expected to double again in the next 20. It is now one of the fastest-growing neurological disorders in the world. In a 2024 paper co-authored with U.S. neurologist Ray Dorsey, [Bas] Bloem wrote that Parkinson’s is “predominantly an environmental disease” — a condition shaped less by genetics and more by prolonged exposure to toxicants like air pollution, industrial solvents and, above all, pesticides. “Parkinson’s was a very rare disease,” Bloem says. “Then with the ... explosion of pesticide use, rates started to climb.”

Financed partly with US taxpayers dollars, [a] firm in Missouri called v-Fluence [was] founded by former Monsanto executive Jay Byrne. [v-Fluence] established a “private social network” to counter resistance to pesticides and genetically modified (GM) crops. A profile of former New York Times food writer Mark Bittman ... includes a description of where he lives, details of two marriages and personal hobbies, and an extensive Criticisms section. Bittman said that it was a “terrible thing,” for taxpayer dollars to be used to help a PR agency “work against sincere, legitimate, and scientific efforts to do agriculture better.” Syngenta signed a contract with v-Fluence in 2002 to help the company deal with negative information coming to light about its paraquat herbicides. v-Fluence went on to help Syngenta create false or misleading online content that was “Paraquat-friendly,” used search engine optimization to suppress negative information about paraquat in Internet searches and investigated the social media pages of victims who reported injuries to Syngenta’s crisis hotline. Syngenta’s internal research found adverse effects of paraquat on brain tissue decades ago but the company withheld that information from regulators, instead working to discredit independent science linking the chemical to brain disease and developing a “SWAT team” to counter critics. In its response to those stories, Syngenta asserted that no “peer-reviewed scientific publication has established a causal connection between paraquat and Parkinson’s disease.”
Note: Read more about how v-Fluence was used to censor the web and silence dissenting voices. “Trust the science” sounds noble—until you realize that even top editors of world-renowned journals have warned that much of published medical research is unreliable, distorted by fraud, corporate influence, and conflicts of interest.
The Environmental Protection Agency must ban the toxic weedkiller paraquat – a step more than 60 other countries have taken because of its threats to human health. Paraquat has been linked to Parkinson’s disease, non-Hodgkin lymphoma, childhood leukemia and more. While the EPA says paraquat is too toxic for use on U.S. golf courses, it still allows use of the herbicide on farms. This threatens the health of the people who apply it, other farmworkers and those who live or work near crop fields where it’s used. More than 10 million pounds of paraquat were sprayed in 2018 alone, twice as much as has been sprayed since 2014. While much of the paraquat applied winds up in the soil for years, the chemical can also drift through the air or linger in dust. Syngenta makes paraquat in China and the United Kingdom. The Swiss-based company, which was acquired by a Chinese state-owned chemical conglomerate, has long understood the chemical’s health risks. But it spent decades hiding this knowledge from the public and the EPA. Ironically, Chinese, U.K. and Swiss farmers are prohibited by their respective governments from using paraquat due to potential health risks from exposure. But the weedkiller isn’t prohibited in the U.S. Ingesting even tiny amounts of paraquat can be lethal. Recently, findings from researchers at UCLA show paraquat sprayed within 500 meters ... of where people lived and worked could more than double a person’s odds of developing Parkinson’s.

The Environmental Protection Agency said last week that it needed more time to study the health impacts of paraquat, a powerful herbicide that has drawn scrutiny for its possible links to Parkinson’s disease, a move that would allow it to remain on the market. Several advocacy groups had sued the EPA over an interim registration decision it issued in 2021 ... on the grounds that it was not protective enough. In a statement, the EPA said additional data was necessary to resolve uncertainty around the risks of inhaling the herbicide. For as long as David Jilbert could remember, he wanted to be a farmer. For five years, Jilbert personally mixed, loaded and sprayed paraquat to control weeds in his vineyard. Then he began having difficulty tying his shoes and buttoning his shirts. He started to walk with a slow, shuffling gait around the winery. He was soon diagnosed with Parkinson’s disease, a degenerative neurological disorder that affects motor functions and causes cognitive impairment, despite having no family history or genetic predisposition to the disease. He and his doctors blame paraquat. Jilbert is among the nearly 6,000 Americans who have filed lawsuits against Syngenta and Chevron, which distributed paraquat products in the United States until 1986. The suits allege that the companies failed to warn consumers about paraquat’s substantial health risks. Paraquat ... is among the most widely used pesticides in the United States.

A study of military veterans has shown the strongest evidence yet that the widespread chemical trichloroethylene (TCE)–used in spot removers, office products and dry-cleaning–is linked to Parkinson's disease. The research focused on service members who were stationed at Camp Lejeune in North Carolina between 1975 and 1985, when levels of TCE in the base's water reached 70 times higher than the Environmental Protection Agency's limit. After accounting for demographic factors, Camp Lejeune veterans were 70 percent more likely to develop the movement disorder than service members stationed at Camp Pendleton in California, where the water was uncontaminated. The large study, published last week in the journal JAMA Neurology, adds to a handful of smaller, earlier papers that found a link between TCE and Parkinson's. TCE, which can be in liquid or vapor form, has been commonly used since the 1920s, including as an inhaled surgical anesthetic and in several cleaning products. Today, it's primarily used in making refrigerants and degreasing metal equipment. The chemical breaks down slowly and can be detected in the air, water and soil. It's also found in one-third of U.S. drinking water. The Camp Lejeune drinking water was contaminated with TCE and other chemicals from 1953 to 1987, per the study, due to leakage from underground storage tanks, industrial spills, waste disposal sites and a dry-cleaning business.

Syngenta, maker of a controversial pesticide linked to Parkinson’s disease, said on Tuesday that it would stop making its paraquat weed killer by the end of June. The announcement comes as the company is facing several thousand lawsuits brought by people in the US who allege they developed Parkinson’s disease due to their exposure to Syngenta’s paraquat products. The company did not mention the litigation in its announcement. Paraquat has been used in the US since 1964 as a tool to kill broadleaf weeds and grasses. Though banned in several countries, including throughout Europe, Syngenta’s paraquat-based Gramoxone herbicide brand has remained popular with US farmers for use in growing soybeans, cotton and corn, as well as in growing grapes, pistachios, peanuts and many other crops. Numerous scientific studies have found that paraquat damages cells in the brain in ways that can lead to Parkinson’s, and more than 8,000 lawsuits are pending in US courts over the Parkinson’s allegations. The New Lede, in conjunction with the Guardian, obtained and revealed many of Syngenta’s internal corporate files, which show that not only was Syngenta aware of research linking paraquat to Parkinson’s decades ago, but it also sought to secretly influence scientific information and public opinion regarding those links. Lawmakers in multiple states have introduced legislation to ban paraquat, and several federal lawmakers have also called for bans.

The World Health Organization’s cancer research agency has classified atrazine – the second most widely used herbicide in the United States – as “probably carcinogenic to humans,” adding to growing concerns about toxic exposures in the nation’s farm belt. The evaluation means the first and second most widely used herbicides in the U.S. – glyphosate and atrazine – are now both considered probable human carcinogens by the world’s leading independent cancer-hazard authority. Atrazine is banned in the European Union and other countries due to health and environmental concerns, but remains widely used in the U.S., where it is a common contaminant in drinking water, according to the Environmental Protection Agency. Despite these concerns, U.S. regulators allow its continued use. The new assessment by the WHO’s cancer agency comes 10 years after the agency’s landmark finding that glyphosate, the world’s most heavily used herbicide, is also “probably carcinogenic to humans.” Both atrazine and glyphosate are also endocrine disruptors, meaning they can disrupt key hormone systems that regulate growth, development and metabolism. Both herbicides are also largely produced by companies outside the United States. Syngenta, owned by ChemChina, produces most of the atrazine used in the U.S., while Bayer, based in Germany, is the dominant producer of glyphosate. The cancer designation for atrazine comes amid reports of rising cancer rates across the U.S. Corn Belt.

Research on ALS, a debilitating condition also known as Lou Gehrig’s disease that leads to muscle weakness and death, has found a link between exposure to pesticides and disease development. A new study led by ... Alison O’Neil provides insight into how a specific pesticide damages the nerve cells affected in ALS patients. The paper, published in the prestigious multidisciplinary journal PLOS One, is a follow up to another study O’Neil conducted on the pesticide known as cis-chlordane, which is banned but persists in the environment. “The goal of the study was to try to figure out why cis-chlordane is able to kill motor neurons,” which are the nerve cells that die in ALS (amyotrophic lateral sclerosis), she said. “It turns out that [the pesticides] are affecting the mitochondria, which are the powerhouse of the cell,” said O’Neil. Without mitochondria, the motor neurons weaken and die. This insight points to potential for more effective treatments for a disease when current therapies extend life by only a few months. “The implications of that finding helps us determine what kind of drugs people need,” said O’Neil. Since there is clearly an environmental component in most cases of ALS, said Clackson, the research can help pinpoint what is contributing to the disease and potentially change disease trajectory. “If we see these early biomarkers, say pesticides in the blood, then we can perhaps treat them earlier and have a completely different outcome,” he said.

Karen McCormack, a retired Environmental Protection Agency (EPA) scientist who spent 40 years with the agency, told Al Jazeera’s investigative show Fault Lines that she believed the EPA was not fulfilling its mission to protect the public from harmful chemicals. “In the last three decades that I have worked at EPA it has been very rare for a toxic pesticide to be taken off the market,” she told Fault Lines. “Just about every, every new pesticide application that is submitted to the agency is approved, no matter how high the risk.” As the Al Jazeera report notes, paraquat is banned in 58 countries but its use is on the rise in the United States. The Guardian’s Paraquat Papers, published in 2022 in collaboration with the New Lede, exposed years of corporate efforts to cover up paraquat’s links to Parkinson’s disease, mislead the public, challenge published scientific literature and influence the EPA. Dr Deborah Cory-Slechta, a prominent researcher, told Al Jazeera: “There is a very strong and compelling body of evidence based on the epidemiology studies and what we know from animal models of Parkinson’s disease” that paraquat causes changes in the brain that lead to Parkinson’s. As revealed by the Guardian, in 2005 Syngenta worked behind the scenes to keep Cory-Slechta from sitting on an EPA advisory panel, deeming her a threat to paraquat. Company officials wanted to make sure the efforts could not be traced back to Syngenta, the documents showed.

It is against the law to use paraquat in China, Switzerland, the United Kingdom and dozens of other countries. Many countries have banned the herbicide due to its extreme toxicity, while others have expressed concerns over the possible risk for Parkinson's disease. Yet the herbicide, manufactured by a Swiss company that is owned by the Chinese state, is still widely used throughout the United States in part because it is a highly effective way to kill weeds. The company, Syngenta, says that paraquat, which it produces under the name Gramoxone, "is safe for its intended and labelled use." Clayton Tucholke, who used Gramoxone for years on his farm in LaBolt, South Dakota, and has since been diagnosed with Parkinson's disease, says otherwise. "It should have been pulled, I think, you know, so it didn't happen to somebody else," Tucholke told ABC News. The Tucholkes are among the more than 4,000 Americans who have filed lawsuits as part of a multi-district litigation against Syngenta, which currently manufactures Gramoxone, and Chevron, which distributed it in the U.S. from 1966 until 1986. Although Syngenta and Chevron told ABC News that there is no scientific evidence that supports a causal link between paraquat and Parkinson's disease, the Tucholkes and other plaintiffs allege that such a link exists, arguing that Syngenta and Chevron knew or should have known that the herbicide could "cause severe neurological injuries."

Carbon markets were first created decades ago as a means for companies to offset their greenhouse gas emissions by paying to reduce emissions somewhere else. Think: planting trees that hold carbon in South America to balance emissions from a factory in South Carolina. And over the last several years, policymakers, environmental and farm groups, and private companies began hyping the idea that specific markets could be created to pay farmers for adopting practices that could reduce emissions and hold carbon in soil. Congress passed the Growing Climate Solutions Act on a bipartisan basis in an effort to jump-start the markets. The two practices that dominate current markets—no-till and cover crops—require herbicides to succeed in the way they’re practiced. Farmers use herbicides to kill weeds that they could otherwise till under and to kill cover crops before planting a cash crop. [Hamilton College researchers raised concerns] that markets would incentivize activities that required heavy chemical inputs, which a farmer would have to purchase from a chemical company. Currently, Bayer, Corteva, and Truterra’s markets all pay farmers primarily to adopt no-till systems and to plant cover crops. And there is a long history of companies using those specific practices to market pesticides linked to serious health risks. As far back as the 1970s, Chevron Chemical promoted paraquat ... as a tool to convert to no-till farming.

Paraquat, one of many pesticides that cant be used in Europe but is sold in the United States and elsewhere, has been linked to Parkinsons disease in a growing body of research. The [paraquat factory in Huddersfield, England] recently celebrated its centennial. Paraquat [is] one of the worlds most enduring weed killers - but not one that can be purchased in ... Britain or across the Channel in the rest of the European Union. So it will be sent to the United States, or another part of the globe that still allows paraquat to be sprayed on weeds. Now regulators in the United States are grappling with a wave of research linking paraquat to ... Parkinsons disease. In a recent ... regulatory filing, the Environmental Protection Agency said, There is a large body of epidemiology data on paraquat dichloride use and Parkinsons disease. The agency is weighing whether to continue allowing the chemical to be sprayed on American cropland, although a decision is not expected until 2018. In the meantime, many of the nations that ban paraquat and other chemicals whose use is contentious still allow them to be manufactured as long as they are exported to faraway fields. Even the government of China, a nation not known for environmental regulation, said in 2012 that it would phase out paraquat to safeguard peoples lives. As Europe and China move away from paraquat, its use is rebounding in the United States. That is particularly true for soybean fields, where the number of pounds used is up more than fourfold over the past decade.
Note: Paraquat is manufactured by Syngenta, a Swiss company known for manipulating international trade deals. For more along these lines, see concise summaries of deeply revealing news articles about corruption in government and in the corporate world.
Pediatrician Carla Nelson ... waited for the ambulance plane to take the infant from Waimea, on the island of Kauai, to the main childrens hospital in Honolulu. It was the fourth [severe heart malformation] she had seen in three years. There have been at least nine in five years, she says, shaking her head. Thats more than 10 times the national rate. Corn thats been genetically modified to resist pesticides [is] a major cash crop on four of [Hawaii's] six main islands. In Kauai, chemical companies Dow, BASF, Syngenta and DuPont spray 17 times more pesticide per acre than on ordinary cornfields in the US mainland. About a fourth of the total are called Restricted Use Pesticides because of their harmfulness. Just in Kauai, 18 tons mostly atrazine, paraquat (both banned in Europe) and chlorpyrifos were applied in 2012. The World Health Organization this year announced that glyphosate, sold as Roundup, the most common of the non-restricted herbicides, is probably carcinogenic in humans. When the spraying is underway ... residents complain of stinging eyes, headaches and vomiting. At these times, many crowd the waiting rooms of the towns main hospital, which was run until recently by Dow AgroSciences former chief lobbyist in Honolulu. The chemical companies that grow the corn ... refuse to disclose with any precision which chemicals they use, where and in what amounts, but they insist the pesticides are safe. Today, about 90% of industrial GMO corn grown in the US was originally developed in Hawaii.

The reputation of Roundup, whose active ingredient is the worlds most widely used weed killer, took a hit on Tuesday when a federal court unsealed documents raising questions about its safety and the research practices of its manufacturer, the chemical giant Monsanto. Monsantos internal emails and email traffic between the company and federal regulators ... suggested that Monsanto had ghostwritten research that was later attributed to academics and indicated that a senior official at the Environmental Protection Agency had worked to quash a review of Roundups main ingredient, glyphosate, that was to have been conducted by the United States Department of Health and Human Services. The files were unsealed by Judge Vince Chhabria, who is presiding over litigation brought by people who claim to have developed non-Hodgkins lymphoma as a result of exposure to glyphosate. The litigation was touched off by a determination made nearly two years ago by the International Agency for Research on Cancer, a branch of the World Health Organization, that glyphosate was a probable carcinogen. Court records show that Monsanto was tipped off to the determination by a deputy division director at the E.P.A., Jess Rowland, months beforehand. That led the company to prepare a public relations assault on the finding well in advance of its publication. Last year, a review by The New York Times showed how the [chemical] industry can manipulate academic research or misstate findings.
Note: The negative health impacts of Monsanto's Roundup are well known. Major lawsuits are beginning to unfold over Monsanto's lies to regulators and the public on the dangers of glyphosate. Yet the EPA continues to use industry studies to declare Roundup safe while ignoring independent scientists.
