Study of Pesticide Mixtures and Intestinal Barrier Dysfunction Further Highlights Regulatory Deficiencies

(Beyond Pesticides, March 13, 2025) Study results published in Pesticide Biochemistry and Physiology “suggest that combined [pesticide] exposure may further amplify the toxicity and compromise the intestinal barrier.” The researchers studied the toxic effects of the insecticides abamectin and spirodiclofen, as well as the fungicide fluazinam, individually and in combination. In exposing mice and Caco-2 cells to these pesticides, the results show the disruption of intestinal functions and highlight the need to assess potential synergistic effects of pesticide mixtures as a part of the regulatory review process.  Effects on the intestinal barriers of mice represent a threat to “the first line of defense against the external environment,” the researchers say. The intestinal mucosal epithelial structure plays an important role in preventing harmful substances from entering the intestines and causing damage to cells.  [Caco-2 cells represent a human cell line, derived from a colon cancer patient’s tissue, and mimic the small intestine. These cells are vital in research as a model of the intestinal epithelial barrier.]  “Currently, most studies investigating the effects of pesticide residues on the barrier function of Caco-2 cells concentrate on the exposure to a single residue, while the potential toxic effects arising from the concurrent presence of multiple pesticide […]

Study Finds Spermiotoxicity and Impacts on Male Mammal Fertility with Ipconazole Fungicide Exposure

(Beyond Pesticides, March 11, 2025) A study in Toxics analyzes ipconazole, a triazole fungicide often used as a coating on treated seeds and as a foliar treatment on the leaves of plants. “Triazole pesticides are widely used throughout the world, but their abuse causes toxic effects in non-targeted organisms,” the researchers state. In the current study, unintended reproductive effects are noted in male sheep (ram) and pigs (also known as porcine or swine). This research focuses on the impact of ipconazole exposure on spermatozoa (sperm) in two mammal species and finds spermiotoxicity through significantly reduced sperm viability, as well as alterations in enzyme and gene expression related to fertility.  “To our knowledge, this is the first study to evaluate the cytotoxic effect of the triazole ipconazole on mammalian spermatozoa,” the authors share. This analysis utilizes semen samples from the Reproductive Biotechnology Laboratory of the Major National University of San Marcos in Lima, Peru, the university where six of the nine researchers are Faculty of Veterinary Medicine.   “The sperm were exposed to ipconazole concentrations of 1, 5, 10, 50 and 100 µM, and to a control without ipconazole,” they say. Similar concentrations have been used in previous cytotoxicity studies with ipconazole. […]

Children’s Health Threatened as Rates of Pediatric Cancers are Linked to Agricultural Pesticide Mixtures

(Beyond Pesticides, March 4, 2025) A study in GeoHealth of pediatric cancers in Nebraska links exposure to agricultural mixtures with the occurrence of these diseases. The authors find statistically significant positive associations between pesticide usage rates and children with cancer, specifically brain and central nervous system (CNS) cancers and leukemia. “Our study is the first to estimate the effect of an agrichemical mixture on the pediatric cancer rate in Nebraska,” the study authors share. “One significant advantage of our study is that we identified the pesticide consistently applied over 22 years in Nebraska counties and then estimated the overall mixture effect of these pesticides on pediatric cancer.” The elevated effect of pesticide mixtures, a reality that is not evaluated in the U.S. Environmental Protection Agency’s (EPA) pesticide registration program, was reported in Oecologia (2008), documenting harm to amphibian populations even if the concentration of the individual chemicals is within limits considered acceptable. (See additional coverage here.) There is a wide body of science highlighting the disproportionate risk of adverse health effects in children with pesticide exposure. Their small size and developing organ systems, propensity to crawl and play near the ground, tendency for frequent hand-to-mouth motion, and greater intake of […]

Glyphosate Weed Killer Contaminates Stem Cells, Is Linked to Blood Cancers and DNA Damage, Study Finds

(Beyond Pesticides, February 27, 2025) In analyzing current scientific literature and data on glyphosate-based herbicides (GBHs), a research article in Environmental Sciences Europe finds that glyphosate (GLY) persists in bones before reentering the bloodstream. The mechanisms in which GLY interacts with important cells for development, called hematopoietic stem cells (HSCs), and breaks and rearranges DNA offer a possible explanation for the heightened risk of cancer, specifically blood cancers like non-Hodgkin lymphoma (NHL), myeloma, and leukemia. “Existing data on GLY/GBH metabolism and genotoxicity provide critical insights into how exposures may be contributing to blood cancers,” according to the study’s author, Charles Benbrook, PhD. Dr. Benbrook continues: “A significant portion of GLY reaching blood moves quickly into bone marrow and then bone, where it can bioaccumulate and persist… Data reviewed herein suggest that a portion of the GLY excreted by most people on a daily basis can be traced to the shedding of calcium-GLY complexes in bone back into the blood supply.” This allows for near-constant contact between glyphosate molecules and hematopoietic stem cells, which are immature cells that can develop into any type of blood cell. Mutations in hematopoietic stem cells can cause blood cancers to emerge. Those at disproportionate risk […]

Microplastics Interact with Pesticides, Exacerbating Environmental Health Threats, Studies Find

(Beyond Pesticides, February 25, 2025) A literature review of over 90 scientific articles in Agriculture documents microplastics’ (MPs) increase in the bioavailability, persistence, and toxicity of pesticides used in agriculture. The interactions between MPs and pesticides enhance the threat of pesticide exposure to nontarget organisms, perpetuates the cycle of toxic chemical use, and decreases soil health that is vital for productivity. “The increasing presence of MPs in agricultural ecosystems has raised concerns about their impact on pesticide bioavailability, efficacy, and environmental behavior,” says study author Kuok Ho Daniel Tang, PhD, a global professor in the Department of Environmental Science at the University of Arizona. He continues, “These synthetic particles interact with pesticides through adsorption and desorption processes, altering their distribution, persistence, toxicity, and uptake by plants and other organisms.” Microplastics in the Environment As Beyond Pesticides has previously reported, microplastics are ubiquitous and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about the width of a human hair; nanoplastics […]

Exposure to Glyphosate Herbicide Adversely Affects Perinatal Health, Study Finds

(Beyond Pesticides, February 20, 2024) Researchers at the University of Oregon found that the rollout of genetically engineered corn in the early 2000s, followed by exponential increases in glyphosate-based herbicides, “caused previously undocumented and unequal health costs for rural U.S. communities over the last 20 years.” Their results “suggest the introduction of GM [genetically modified] seeds and glyphosate significantly reduced average birthweight and gestational length.” The conclusions of this study emerge as fossil fuel advocates, including President Donald Trump, are mobilizing to pioneer “energy dominance” despite the market movement toward renewable energy. Just as chemical-intensive farmers and land managers continue to spray synthetic fertilizers and pesticides, a successful rollout of alternatives must rely on feeding the soil rather than the plant. Advocates continue to demand that elected officials and regulators embody the precautionary principle and scientific integrity in decision-making. Given the hostile federal climate on anything relating to holistic solutions, communities are coming together to move beyond input-dependent land management systems and adopt organic criteria of allowed and prohibited substances, mandatory public comment process, independent third-party certification, and a federal advisory board (National Organic Standards Board) consisting of farmers, environmentalists, consumers, scientists, economists, researchers, and other stakeholders, with binding recommendations […]

Study Finds Increased Offspring Mortality in Pesticide-Laden Bird’s Nests

(Beyond Pesticides, February 11, 2025) In a Science of The Total Environment study, scientists test over 100 blue tit (Cyanistes caeruleus) and great tit (Parus major) birds’ nests for pesticide residues in comparison with the number of dead offspring and unhatched eggs within the nest. Fur-lined nests, from animals treated with ectoparasitic chemicals, expose birds to compounds that can impact reproductive success. The authors found fipronil, a phenyl pyrazole insecticide, in all nests, with the majority also containing the neonicotinoid insecticide imidacloprid and synthetic pyrethroid insecticide permethrin. The data shows higher insecticide levels are linked to increased offspring mortality and threaten biodiversity. This study highlights an important exposure route that is overlooked. “Although not all bird species use fur for nest building, a substantial number do, especially cavity-nesting species,” the researchers share. “Previous research found that 74% of studied woodland bird species in central Europe incorporated fur into their nests.” Many bird species in the U.S. also line their nests with fur, such as black-capped chickadees, tufted titmice, and chipping sparrows. While there is a wide body of science showing reproductive effects from pesticides, the researchers highlight the study’s novel design, saying, “To the best of our knowledge, no previous […]

Pesticides that Adversely Affect Cell Function Linked to Brain Cancer

(Beyond Pesticides, February 7, 2025) With the strong associations established in epidemiologic studies and a dearth of evidence on the actual mechanisms by which pesticides inflict their damage on the brain, a new meta-analysis identifies studies that pesticides can overwhelm cells’ defenses against them, interfere with cell communication in the brain, and disrupt the epigenetic (gene function) regulation of gene expression. In the journal Nucleus, Bilal Ahmad Mir, PhD and colleagues at the University of Kashmir in Srinagar, India, review what is known at the molecular level about pesticides’ role in brain cancer. Brain cancer is a heavy burden for its victims and their families, and attributing a cause is, as with many diseases, fraught with difficulty. But there are strong clues: For example, farming is a known risk factor. In a 2021 meta-analysis of epidemiologic studies between 1998 and 2019, analyzed here by Beyond Pesticides, farming was associated with a 13% increase in the risk of brain cancer. For farmers whose specific exposure to pesticides was documented in the studies, the increase jumped to 20 percent. So there is some reason to point a finger at synthetic chemicals. But agricultural workers are not the only ones at risk. According […]

Revealing “Dirty Weed”: Pesticides in Cannabis Raises Health Concerns, as Advocates Advance Organic Solution

(Beyond Pesticides, February 6, 2024) Months after publishing a June 2024 study regarding concentrations of pesticides discovered in legal (and illegal) cannabis products in California, the Los Angeles Times has released a follow-up exposĂ© highlighting extensive pesticide contamination, including from “hidden” pesticides that regulators have not monitored. The authors conclude that in California’s legal weed market, over half of available smoking products are found to contain hidden chemicals—toxic pesticides present in products but not regulated or monitored by state authorities. Since 2015, Beyond Pesticides has laid out health, safety, and environmental concerns related to the contamination of cannabis by pesticides (and fertilizers) alongside an imperative need to mandate an organic systems approach to cannabis production. Yet ten years later, it appears nationally that California state regulators are alone in moving forward in 2021 with state organic cannabis certification. There are other marketplace-based cannabis certification labels that require comparable organic certification practices (see Beyond Pesticides reporting here and here). For more information, please see past Pesticides and You reporting here and here. The Los Angeles Times analyzed the results from state licensed laboratory testing of more than 370 legal cannabis products, representing 86 brands. In addition to the 66 chemicals required […]

Neonic Insecticide Impairs/Kills Beetle Listed as Threatened and Important to Ecosystem Health, But Not Protected

(Beyond Pesticides, February 5, 2025) A study in PLOS One finds acute and chronic impacts of nontarget toxicity on the American burying beetle, Nicrophorus americanus, with neonicotinoid insecticide exposure. In assessing environmentally relevant concentrations of the neonicotinoid insecticide imidacloprid with N. americanus, the researchers note both mortality and behavioral effects that leave the species at high risk of predation. These effects mean the American burying beetle “may be at greater risk to insecticide exposure than previously thought and vulnerable to episodic, low-dose neonicotinoid exposure,” the authors say. This data sheds important light on a species that has been listed by the U.S. Fish and Wildlife Service (USFWS) as threatened. Burying beetles provide important ecosystem services within the environment such as “burying carrion, increasing available nutrients in soil, and expediting carrion decomposition, while acting as a food source for secondary consumers,” the researchers state. (See more on ecosystem services and beneficial insects here, here, and here.) The N. americanus species are habitat generalists and can be found in grasslands, wet meadows, and forested areas that neighbor agricultural lands and introduce the beetles to pesticide drift and soil residues. While acute and chronic effects vary in duration and severity, pesticide exposure resulting […]

Sleep Disorders in Farmers and Farmworkers Linked to Pesticide Exposure in Study Supporting Similar Findings

(Beyond Pesticides, January 31, 2025) A recent cross-sectional study in Heliyon highlights the link between sleep disorders in Thai farmers and pesticide exposure. The authors find pesticide exposure as an important risk factor for sleep disorders after surveying 27,334 farmers over the age of 20 who had work experience for at least five years. The importance of sleep health is reflected both physically and mentally, as studies find “sleep deficiency increase[s] mortality and various health complications, including hypertension, obesity and type 2 diabetes, cardiovascular diseases, mood disorders, and neurodegenerative disorder.” Additional studies find that these issues are compounded when sleep health is affected by environmental factors such as pesticide exposure. (See previous Beyond Pesticides’ coverage here and here.) The researchers report: “The study found a positive association of 19 individual pesticides (twelve insecticides, two herbicides, and five fungicides). Some associations demonstrated a dose-response pattern. Additionally, the study revealed that women are at a higher risk of sleep-related issues with pesticide exposure compared to males. These results not only substantiate existing literature but also unveil several new individual pesticides that may impact sleep health.” Focusing on study participants in Thailand, which is “characterized by heavy pesticide use and minimal protective measures, […]

Study Finds Pesticide Exposure to Bees During Dormancy or Overwintering Disruptive of Reproductive Health

(Beyond Pesticides, January 30, 2025) A research article in Biology Letters, published by The Royal Society, finds that the neonicotinoid insecticide imidacloprid disrupts survival and reproductive patterns in Bombus impatiens bumblebees. The study adds to the wide body of science highlighting how exposure to pesticides “can result in immediate mortality or cause long-term detrimental effects on pollinators‘ health, lifespan and reproductive success,” the authors state. The researchers performed two experiments to assess the effects of various concentrations of imidacloprid, one of which focuses on bees during diapause, a period of dormancy. “Wild bees, which provide the majority of pollination services worldwide, undergo an annual life cycle that includes a winter diapause, that can span over 75% of their life cycle and during which their metabolism, growth and development are halted,” the authors note. They continue: “The time spent in diapause can have lasting effects on pollinator fitness and their ability to establish nests or colonies in the following spring. This period is especially critical for social bee colonies, which are founded by a single queen after diapause and play a vital role in large-scale pollination.” Exposure to pesticides during diapause can occur while bee species overwinter in contaminated soils.

Waterway Contamination Findings with Neonicotinoid Insecticide a Threat to Aquatic Ecosystems and Biodiversity

(Beyond Pesticides, January 24, 2025) Based on data collected from government sources and independent monitoring, a multidisciplinary team of researchers at the University of Connecticut finds that 46% of Connecticut waterway samples are contaminated with levels of the neonicotinoid insecticide, imidacloprid—one of the most widely used insecticides in the United States on lawn and golf courses. The authors relied on federal data from U.S. Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS), state-level data from Connecticut Department of Energy and Environmental Protection (CT-DEEP), and a small-scale data collection study by the Clean Rivers Project funded by the nonprofit Pollinator Pathway, Inc. In their report, Neonicotinoids in Connecticut Waters: Surface Water, Groundwater, and Threats to Aquatic Ecosystems, the researchers provide the most comprehensive view to date of neonicotinoid levels in Connecticut and offer critical recommendations for future testing within the state and nationally, given glaring data gaps. It is important to note that the authors acknowledged early in the report the “abandonment” of Integrated Pest Management in “the use of neonicotinoids has coincided with and been implicated in the decline of many non-target species of insects, in particular pollinators such as bees () and monarch butterflies.” They point out that […]

Viability of Hemp as a PFAS Remediation Tool Moves Forward, as Contamination Spreads

(Beyond Pesticides, January 23, 2025) According to reporting by Bangor Daily News, “Starting in 2025, the Mi’kmaq Nation, [Upland Grassroots], [University of Virginia], the Connecticut Agricultural Experiment Station and Central Aroostook Soil and Water Conservation District will use a four-year, $1.6 million EPA grant to continue hemp planting at [the former] Loring [Air Force Base] and testing potential ways to extract PFAS [per- and polyfluoroalkyl substances] from harvested hemp.” This grant will support an existing initiative led by members of the Mi’kmaq Nation to remediate this contaminated Superfund-designated land purchased from the U.S. government in 2009 based on interviews of the Nation’s Vice Chief Richard Silliboy.   PFAS, colloquially known as “forever chemicals,” persist in various petrochemical-based pesticides, chemicals, and other consumer products. Beyond Pesticides, in coordination with national coalitions and local communities, continues to act against the proliferation of PFAS and PFAS-contaminated products through grassroots organizing and litigation. The use and associated public and environmental exposure to PFAS as pesticide active ingredients in pesticide products and a wide range of consumer products (including containers holding pesticides targeting mosquitoes and sewage sludge fertilizers) represent a grave threat as a result of their use in homes, emergency rooms, health care facilities, […]

Multitude of Studies Find Epigenetic Effects from PFAS and Other Endocrine Disrupting Pesticides

(Beyond Pesticides, January 16, 2025) In Ecotoxicology and Environmental Safety, researchers highlight a multitude of studies on endocrine disrupting chemicals (EDCs) and endocrine disrupting pesticides (EDPs) showing epigenetic effects from exposure. These EDCs imitate the action of endocrine hormones and lead to gene damage and multigenerational adverse effects to health. “These chemicals can interfere with the normal functioning of target tissues by altering their response to hormonal signals, thereby affecting various physiological processes including reproduction, development, the nervous system, the immune system, and even the process of carcinogenesis [causing cancer],” according to the authors from Hebei Agricultural University and Chinese Academy of Agricultural Sciences.   In causing epigenetic modifications, the authors describe that EDCs can create changes “at the nuclear and mitochondrial DNA (nDNA and mtDNA) or RNA levels, without changing the underlying DNA sequence. These alterations modify the structure or conformation of DNA, influencing gene expression and, consequently, cellular function.” They continue, “The mechanisms of epigenetics include changes in DNA methylation, chromatin modifications and the involvement of certain noncoding RNAs.” In reviewing over 80 studies on EDCs, predominantly fluorinated compounds such as per- and polyfluoroalkyl substances (PFAS), the researchers provide a summary of linkages between pesticide exposure and the […]

Lit Review Shows Depth of Research Linking Pesticide-Induced Effects on Immune System, Leading to Disease Outcomes

(Beyond Pesticides, January 15, 2025) There is robust scientific literature that unpacks the adverse human health effects of pesticide exposure, however immunological impacts do not receive adequate attention in regulatory review processes, according to an in-depth literature review. In a piece published in Frontiers in Immunology (2024) critiquing recent peer-reviewed scientific studies, as well as unpublished research produced by the Institute of Biology and Experimental Medicine in partnership with the National Scientific and Technical Research Council in Argentina, researchers assess immune system effects of pesticide exposure, which creates the conditions for deadly health conditions including various forms of cancer. The focus of this study, according to the authors, is “to critically review fundamental aspects of toxicological studies conducted on PPPs [Plant Protection Products] to provide a clearer understanding of the risks associated with exposure to these compounds on human health.” PPPs are pesticide products that contain more than one active ingredient, and can include synergistic ingredients that supercharge them alongside inert ingredients that pesticide companies are not legally required to disclose under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), but are often manipulated biologically and chemically active. Most studies analyze the toxicological impacts of active ingredients in isolation rather […]

Multiple Studies Link Adverse Effects on Female Reproductive Health with Endocrine Disrupting Chemical Exposure

(Beyond Pesticides, January 9, 2025) In a Frontiers in Public Health review article, researchers report on the wide body of science connecting adverse effects to female reproductive system, such as infertility, with exposure to endocrine-disrupting chemicals (EDCs). The authors call these effects a significant concern for public health, as there has been growing evidence of EDCs with risk factors for decreased fertility.   Infertility “affects a substantial proportion of the world’s population with approximately one in six people affected,” the researchers note. They continue: “Over the last 70 years, global fertility has been constantly in decline due to behavioral and societal changes… [E]merging evidence has shown that infertility incidence is linked to exposure to environmental factors such as tobacco, alcohol, and a wide range of endocrine-disrupting chemicals (EDCs) including pesticides (chlorpyrifos, glyphosate, dichlorodiphenyltrichloroethane [DDT] and methoxychlor), phthalates, polychlorinated biphenyls (PCB), dioxins, and bisphenols.”  In this review, over 100 studies are summarized to showcase the link between EDC exposure and reproductive effects in women, including infertility and related diseases such as endometriosis, premature ovarian insufficiency (POI), and endocrine axis dysregulation. The studies included investigating the “mechanisms by which EDCs cause ovarian aging, folliculogenesis, decrease of oocyte quality, ovulation disorders, development and receptivity […]

Biodiversity Threatened by Pesticide Drift, Study Finds; Organic Agriculture Cited as a Holistic Solution

(Beyond Pesticides, January 3, 2025) Pesticides that are sprayed and become airborne significantly disrupt ecological balances and affect nontarget species that are crucial for maintaining biodiversity, according to an article in Environmental Pollution. In this review of studies throughout countries in North and South America, Europe, and Asia, among others, researchers from Germany, Norway, the United Kingdom, and Poland reinforce the science about pesticides’ direct effect on species and the cascading effects of pesticide drift through various trophic levels within food webs that lead to overall devasting population effects. This study “addresses the interconnectedness of these impacts and illustrates the complex threats that pesticide drift poses to biodiversity across multiple ecosystems,” the researchers state. They continue: “Impacts include reduced reproductive rates, changes in growth, development, and/or behavior, modification of diversity or community organization, disruption of food webs, and declines of important species. Pesticides disrupt the delicate balance between species that define a functioning ecosystem. Impacts can be local, transnational, or even continental.” Pesticide drift threatens beneficial species and subsequently the entire agricultural system. The process of pesticide drift, “in which up to 25% of applied pesticides are carried by air currents, can transport chemicals over hundreds or even thousands of […]

Mechanism for Escalating Antibiotic Resistance in Agriculture Detailed in Study, as Crisis Grows

(Beyond Pesticides, January 2, 2025) Adding to the body of scientific literature on the fast escalating antibiotic resistance crisis is a study published by Chinese scientists in Environmental Science & Technology, which shows that antibiotic resistance genes (ARGs) in soils move up through trophic levels via predation. Gut microbiomes of soil fauna have been found to be reservoirs of ARGs. How this process operates in soils is vital, because what happens in soil microbes does not stay there. If bacteria altered in soils move up trophic levels, ARGs may strengthen the multicellular agricultural pests the industry is trying to kill—insects, fungi, plants—not to mention bringing their libraries of resistant genes into the microbiomes of vertebrates, including humans. Antibiotic resistance is a natural phenomenon, but human activity has greatly increased its presence in ecosystems the world over, including in one of the ecological niches of greatest concern to the future of food and human health: soils. Soils are complexes of mineral and organic substrates populated by billions of microorganisms and tiny animals. They are rapidly being degraded by conventional agriculture, forestry, and land management practices generally—more than a third of the world’s agricultural land has already been severely damaged by pesticides, […]

Deadly Poisoning of Dozens of Children in South Africa Highlights Global Pesticide Threat to Human Life  

(Beyond Pesticides, December 19, 2024) As The New York Times reported last month, the government in South Africa declared a national emergency—23 children died and nearly 900 people were sickened from pesticide poisoning in Johannesburg’s Soweto township. The illnesses and fatalities have been traced to small amounts of highly neurotoxic pesticides, including the insecticides terbufos and aldicarb, found in local food items. These chemicals, described by South African President Cyril Ramaphosa as “street pesticides,” are being increasingly used (legally and illegally) for pest infestations in the townships and informal settlements of South Africa’s poorest communities, where poverty and inadequate waste collection exacerbates the pest management challenges. Without formal electricity, running water, or municipal garbage collection, many residents rely on highly toxic pesticides for pest infestations in their homes and makeshift markets, resulting in food inadvertently being contaminated with pesticides.  The announcement highlights the dangers of allowing these highly toxic agricultural chemicals to be used in farming, with tragic consequences for vulnerable communities when they are diverted for use in urban settings. This tragic situation also draws attention to the elevated threat that pesticides pose when stringent enforcement mechanisms are not in place to ensure compliance with pesticide restrictions, even with […]

Investigative Report Finds Canada’s Reversal of Neonicotinoid Ban Influenced by Bayer/Monsanto

(Beyond Pesticides, December 18, 2024) A bombshell investigation conducted by Canada’s National Observer finds that Bayer, which acquired the Monsanto chemical company in 2018, colluded with environmental and public health regulators in Canada to obstruct a proposed neonicotinoid insecticide ban originally introduced in 2018. Advocates were stunned back in 2021 when Canada’s Pest Management Regulatory Agency (PMRA)—the Canadian counterpart to the U.S. Environmental Protection Agency (EPA)—reversed its decision to phase out imidacloprid, clothianidin, and thiamethoxam by 2023. The weaponization of scientific institutions and regulatory processes is commonplace in the U.S. context, with U.S. Right to Know publishing a report earlier this year on the corrupting impact of pesticide manufacturers at the Entomological Society of America 2023 annual meeting. (See Daily News here.) There are numerous Office of Inspector General (OIG) reports signaling EPA corruption and failures, including persisting industry influence in the cancer risk assessment process, inadequate leadership in addressing community harms of a former creosote-treated wood preservative plant turned Superfund site in Pensacola, Florida, and failure to protect the public from endocrine-disrupting chemicals, to name several examples. In a recent press release, the David Suzuki Foundation, alongside numerous medical, legal, and civil society organizations, is calling on Health Canada […]

Study Links Numerous Chemical Families of Pesticides to Endocrine Disrupting Effects, Including Obesity

(Beyond Pesticides, December 17, 2024) A systematic review of studies on pesticides as endocrine-disrupting chemicals (EDCs) on body weight, published in Biomedicines, evaluates 36 clinical and preclinical studies and links their agricultural use to obesity. The authors, with the lead researchers from the School of Medicine and Health Sciences at Catholic University of Valencia San Vincente, Valencia, Spain, assess studies on a range of pesticides, including organophosphates, pyrethroids, neonicotinoids, and others. In addition to concluding that the EDCs promote obesity, they report that the chemicals cause “other anthropometric changes by altering lipid and glucose metabolism, modifying genes, or altering hormone levels such as leptin.” Endocrine disruption and obesity are public health concerns, and there is a wide body of science linking pesticide exposure to these effects (see more here). “Obesity is considered to be a worldwide pandemic that leads to an increase in medical costs and thus becomes a public health problem,” the researchers share. They continue, “[Obesity] is also associated with the increased production of environmental chemicals, also called environmental obesogens, used mainly in agriculture, as disease vector control, helping to prevent harmful effects caused by fungi, bacteria, or even pests, using pesticides, insecticides, and herbicides, or endocrine disruptors […]

California is proposing the continued use of the fumigant 1,3-dichloropropene (1,3-D, also known as Telone), which can cause deadly effects to farmworkers and endocrine disrupting effects to communities of people exposed through nontarget chemical drift from farmland. So, it is with deep concern that Beyond Pesticides is urging the state of California, where the chemical is undergoing review, to ban the toxicant. Endocrine disruption, an adverse effect for which the U.S. Environmental Protection Agency (EPA) has never completed a pesticide testing protocol, adversely affects the functioning of glands and hormones and is linked to major life-threatening diseases in most organ systems in the body—contributing to attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, diabetes, cardiovascular disease, obesity, early puberty, infertility and other reproductive disorders, and childhood and adult cancers. In a recently released draft regulation, the California Department of Pesticide Regulation (CDPR) will allow highly elevated exposure to 1,3-D, ignoring the scientific literature and advice of the state’s own toxicologists at […]
