(Beyond Pesticides, June 23, 2025) At the close of National Pollinator week, Beyond Pesticides says in an action that all species—and their ecosystem—are threatened by the failure of the U.S. Environmental Protection Agency (EPA) to perform its statutory duties under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Endangered Species Act (ESA).  Under FIFRA, EPA is required to register pesticides only when they pose no “unreasonable risk to man [sic] or the environment, taking into account the economic, social, and environmental costs and benefits.” Under ESA, EPA must, like all federal agencies, “seek to conserve endangered species and threatened species and shall utilize their authorities in furtherance of the purposes” of the ESA—which are “to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, to provide a program for the conservation of such endangered species and threatened species, and to take such steps as may be appropriate to achieve the purposes of the treaties and conventions” through which “the United States has pledged itself as a sovereign state in the international community to conserve to the extent practicable the various species of fish or wildlife and plants facing extinction.”  In this context, Beyond Pesticides […]

(Beyond Pesticides, June 17, 2025) Funding cuts in the current budget bill include drastic cuts in research essential to protect farmers, farmworkers, and their families. There are many federal agencies funding research, but among the most important of those funding research affecting farmers, farmworkers, and their families are the U.S. Environmental Protection Agency (EPA) and the National Institute for Occupational Safety and Health (NIOSH).   >> Tell Congress to restore funding that protects the health of farmers, farmworkers, and their families. EPA funding for the Bioecological Center for Research on Children’s Health (BeRCH) project was cut after almost two years. This project had the potential to address farmworker children’s health. Farmworker children can face many challenges–including poverty, language barriers, inadequate housing, discrimination, fear of family separation, exposure to agricultural chemicals, food insecurity, and migration. BeRCH was designed to identify, understand, and address the cumulative impacts on the health, development, and growth of farmworker children. The project goals were to examine farmworker children’s exposures to environmental toxins (pesticides, heavy metals, particulate matter) and non-chemical psychosocial stressors (poverty, food insecurity, trauma, discrimination, etc). Working in collaboration with the Florida State University (FSU) health clinic in Immokalee, the project would have examined threats, implemented strategies to improve health outcomes for farmworker children, and collaboratively established […]

(Beyond Pesticides, June 13, 2025) A report highlights the ongoing stress to the Chesapeake Bay Watershed from pollutants, particularly pesticides. The Chesapeake Bay is the largest estuary in the contiguous United States, with tributaries shared among six states and the District of Columbia. It receives runoff from nine major river systems traversing a wide mix of land uses, with significant agricultural and urban areas nearest the Bay and forest along the western boundary. Nearly 13 million people get their drinking water from the watershed. The watershed report by the Maryland Pesticide Education Network focuses primarily on the herbicide atrazine, the neonicotinoid insecticide thiamethoxam, and per- and polyfluorinated compounds (PFAS). Atrazine needs little introduction, being notorious for disrupting hormones, particularly estrogen, as demonstrated by the pioneering work of Tyrone Hayes and more recent research analyzed by Beyond Pesticides here, here and here. In male fish, it can trigger production of egg proteins, especially vitellogenin, and development of eggs in their testicles. These are manifestations of intersex, in which an organism shows forms of sexual differentiation of both sexes. The Chesapeake watershed report notes that atrazine and metolachlor (also an estrogen/androgen disruptor and suspected human carcinogen) occur together frequently in the Chesapeake […]

(Beyond Pesticides, June 10, 2025) An industry-led campaign to quash lawsuits against chemical manufacturers because of their “failure to warn” about the hazards of their pesticide products has failed to move forward in nine state legislatures with significant GOP majorities (Iowa, Missouri, Idaho, Florida, Tennessee, Mississippi, Wyoming, Montana, and Oklahoma). As the Making America Healthy Again (MAHA) Commission released its first report to assess the root causes of childhood diseases and adverse health conditions, there continues to be an ongoing fight among forces within the Trump Administration on whether pesticides should even be mentioned. (See here for The New York Times coverage.) As federal funding cuts make their way through the Budget Reconciliation process, communities around the country are calling on their elected officials to protect their right to sue pesticide manufacturers with failure-to-warn claims; in an era of deregulation and ongoing failure of our regulatory agencies to assess potential associated harms, advocates demand the preservation of this legal right.  Status Report on State-Level Legislation  The only state that has active legislation, as of today’s writing, is North Carolina. The failure-to-warn language was inserted into the annual state Farm Bill package (SB 639) in Section 19, leading to public outcry in the Senate Judiciary Committee hearing on […]

(Beyond Pesticides, June 2, 2025) One focus of the Make America Healthy Again (MAHA) Commission report* is children’s exposure to environmental chemicals and its link to health risks, particularly cumulative risk and chronic disease. With the evidence showing that the current approach to regulating pesticides and other chemicals fails to protect children’s health, it remains to be seen whether next steps will seek an overhaul and reorientation on the United States’ current reliance in chemical-intensive agriculture on hazardous pesticides that have been proven unnecessary by productive and profitable organic food production and land management systems, according to advocates. Beyond Pesticides and advocates are calling on the U.S. Department of Health and Human Services (HHS) Secretary, Robert F. Kennedy, Jr. to promote organic practices and protect children’s health from pesticides through the setting of pesticide tolerances on food, or allowable levels of pesticide residues—taking back an authority given to the U.S. Environmental Protection Agency (EPA) under a memorandum of understanding. The Food and Drug Administration, under HHS, is authorized to set tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA), and EPA is authorized to register pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The predictable response from […]

(Beyond Pesticides, May 30, 2025) The Making America Healthy Again (MAHA) Commission report, Make Our Children Healthy Again: Assessment, published on May 23, drew criticism from the pesticide industry and agribusiness allies for pointing to independent science that identifies a range of pesticide-induced health hazards.* The Commission, chaired by Robert F. Kennedy, Jr., Secretary of the Department of Health and Human Services (HHS), is composed of the heads of numerous agencies of the federal government and the White House, from the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), and the Office of Management and Budget (OMB), to the Assistant to the President and Deputy Chief of Staff for Policy Stephen Miller. The MAHA Commission was established by Executive Order 14212 on February 13, 2025. Despite extensive citations to the science on pesticide hazards, the report includes a section on “Crop Protection Tools,” in which there is a repetition of chemical industry talking points that pesticide residues in food comply with existing tolerances, thus implying that pesticides in food are safe. (See USDA Pesticide Data Program Continues to Mislead the Public on Pesticide Residue Exposure.) However, overall the report’s introduction sets a tone that seeks to catalogue […]

(Beyond Pesticides, May 19, 2025) The Trump administration has removed crucial protections established under the Migratory Bird Treaty Act (MBTA), including those that protect birds from pesticide poisoning. The Migratory Bird Protection Act (MBPA), introduced in May by Rep. Jared Huffman (D-CA) and Rep. Brian Fitzpatrick (R-PA), will restore protections against an “incidental take.” Beyond Pesticides is calling for the protection of migratory birds and the restitution of funds to implement the law. This is not the first time that President Trump has reduced protection for migratory birds. In his first term (2017), the Department of the Interior issued a policy that relieved industries of the requirement to protect birds, and they will no longer be held accountable for bird deaths. In addition, the agency is expected to propose rules to make this policy change permanent. >> Tell your U.S. Representative to cosponsor the Migratory Bird Protection Act (H.R. 3188).  MBTA was passed in 1918 to protect migratory birds soon after the last Passenger Pigeon died in captivity, followed by the last Carolina Parakeet. MBTA originally resulted from the loss of birds due to a number of threats—notably at the time, the collection of bird feathers. It prohibits the take (including killing, […]

(Beyond Pesticides, May 15, 2025) The United Nations’ Conference of Parties (COP) for the Stockholm Convention on Persistent Organic Pollutants (POPs), originally adopted by 128 countries in 2001, voted to move the highly neurotoxic organophosphate insecticide chlorpyrifos, linked to brain damage in children, to Annex A (Elimination) with exemptions on a range of crops, control for ticks for cattle, and wood preservation, according to the POPs Review Committee. The exemptions drew criticism from groups seeking to eliminate chlorpyrifos without exemptions, as had been originally proposed. In the world of pesticide restrictions, this POPs classification marks a step forward in the international regulation of chlorpyrifos, as the U.S. sits on the sidelines. The long effort to ban this one hazardous pesticide, as important as the action is, serves as a reminder of the limitations of a whack-a-mole approach to chemical regulation of the thousands of toxic products poisoning people and the planet, filled with compromises to public health and the environment—while alternative practices and materials are available to meet productivity, profitability, and quality of life goals. According to Down to Earth, the 18 specific crop and use exemptions include the following: Barley (termites), Cabbage (diamondback moth), Cacao (cacao-mosquitoes and cacao pod […]

(Beyond Pesticides, May 6, 2025) A study in Ecology Letters finds “severe degradation of ecosystem functioning in the form of loss of organic matter consumption and dramatic shifts in primary productivity,” the researchers state, after performing an experiment with “36 naturally established freshwater ecosystems exposed to increasing field-realistic concentrations of the neonicotinoid thiacloprid.” Aquatic communities contribute to overall biodiversity and are crucial in maintaining healthy ecosystems; without them, the entire food web and vital ecosystem services, such as nutrient cycling, water filtration, and climate regulation, are threatened. As the authors reference, there is a current unprecedented decline in biodiversity that can be attributed to anthropogenic impacts. A multitude of studies connect pesticides, and more specifically neonicotinoid insecticides, to impacts on aquatic ecosystems. (See studies here and here.) “Since the community of organisms locally present is responsible for the functioning of the local ecosystems,” the researchers begin, “this begs the question: do neonicotinoid-induced shifts in community composition result in a degradation of ecosystem functioning?” Previous research finds that neonicotinoids can “impede several freshwater ecosystem processes such as organic matter (‘OM’) decomposition, primary production or biomass transfer to neighbouring ecosystems,” the authors say. (See studies here, here, and here.) They continue: “However, […]

(Beyond Pesticides, May 1, 2025) Pesticides by themselves are a grave threat to global health. As is global warming. As is antibiotic resistance. Each of these problems has to be analyzed in its own silo to reveal the mechanisms driving its dynamics. But eventually, it must be acknowledged that they actually converge. A common soil arthropod has clearly illustrated how this convergence creates synergistic effects: warming increases pesticide toxicity; pesticide toxicity triggers antibiotic resistance; antibiotic resistance spreads through horizontal gene transfer (movement through the environment to people) and predation. The consequences, not yet fully understood, are nevertheless emerging from accumulating research. A study published in the Journal of Hazardous Materials by scientists at six Chinese universities and research centers examines the convergence in springtails (Folsomia candida)—tiny insect-like animals that live in soils worldwide and are commonly used as laboratory subjects. The researchers exposed springtails to the neonicotinoid insecticide imidacloprid at three concentrations and three temperatures. In addition to measuring the springtails’ direct mortality, the researchers also investigated the microbes in the animals’ guts, checking for expression of genes involved in antibiotic resistance. The evidence is unequivocal: imidacloprid exposure at a soil temperature consistent with current and expected warming (30°C, or […]

(Beyond Pesticides, April 23, 2025) Recent reviews of scientific literature, in both Chemosphere and Reports in Public Health, associate Parkinson’s disease (PD), the second most prevalent neurodegenerative disease globally, with pesticide exposure. “Given the pervasive nature of pesticide residues in everyday food consumption and inadequate monitoring of their long-term toxicological impacts, the role of pesticide exposure as a modifiable risk factor for neurological disorders, including PD, warrants urgent attention,” the researchers state in the article in Chemosphere. In describing the history of Parkinson’s and previous research, the authors in Reports in Public Health note that while PD etiology is not fully understood, it is a multifactorial disease. “Hereditary factors are present in approximately 10% of diagnosed cases of Parkinson’s disease, presenting early onset; while the other 90% of cases are categorized as idiopathic or sporadic Parkinson’s disease, occurring in older individuals and may be associated with exposure to environmental agents,” the researchers say. This disease, first described by English physician James Parkinson, M.D. in 1817, involves neurochemical changes that present as “the appearance of cardinal motor symptoms, such as bradykinesia, rigidity, postural instability, and rest tremor, which are essential for the clinical diagnosis of the disease,” the researchers note. The […]

(Beyond Pesticides, April 14, 2025) The Trump administration has undertaken an unprecedented attack on science in regulatory, research, and educational institutions, with predicted adverse consequences for all people across the country. The Union of Concerned Scientists last week published a list of organizations and their tracking of Trump’s dismantling of federal science programs, including health research and the impact by Congressional district. And, the Environmental Protection Network estimates that the announced rollbacks at the U.S. Environmental Protection Agency would erase $254 billion in health and economic benefits. Perhaps it is understandable that those who oppose environmental and health regulations that put limits on industry would favor cuts to regulatory agencies. However, the impacts of the current cuts go far beyond deregulation.  >> Tell your U.S. Representative and Senators to reverse Trump Administration cuts to science.  The cuts to agencies affect science at every level. Science funding has been slashed at EPA, the National Institutes of Health (NIH), Health and Human Services (HHS), Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH), National Oceanic and Atmospheric Administration (NOAA), and U.S. Department of Agriculture (USDA). And these cuts have implications for, among other things, clean air and water, protection from wildfires, cures for diseases ranging from Alzheimer’s to childhood cancer, monitoring and protection from lead […]

(Beyond Pesticides, April 9, 2025) On March 12, 2025, the U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced the agency would be shutting down the Environmental Justice and Diversity, Equity, and Inclusion (DEI) offices and staff at ten of the regional offices and the headquarters in Washington, D.C. Administrator Zeldin declared that this move implemented President Donald Trump’s Executive Order, “Ending Radical and Wasteful Government DEI Programs and Preferencing.” In response to this decision, ten Democratic U.S. Senators—led by Senator Alex Padilla (D-CA) and including Senators Richard Blumenthal (D-CT), Cory Booker (D-NJ), Tammy Duckworth (D-IL), Edward J. Markey (D-MA), Jeff Merkley (D-OR), Bernie Sanders (I-VT), Adam Schiff (D-CA), Chris Van Hollen (D-MD), Sheldon Whitehouse (D-RI), and Ron Wyden (D-OR)—co-sponsored the Empowering and Enforcing Environmental Justice Act of 2025 to Congress that would codify funding for environmental justice offices in the Department of Justice. (See Sen. Padilla’s press release here.) Senators Duckworth and Booker—founding co-chairs of the Senate Environmental Justice Caucus—also issued the following statement: “Underserved communities in rural, urban and tribal areas already shoulder the brunt of the climate crisis and environmental injustice. These cuts and reversals will make it even harder for these communities to address some of […]

(Beyond Pesticides, April 4, 2025) In March, the California Department of Pesticide Regulation (DPR) announced the launch of SprayDays California, “a first-of-its-kind statewide system designed to provide transparent, accessible and timely notifications and information about the use of specific pesticides[,]“ according to the agency’s press release. The state says that notification will occur in “advance of the scheduled use of California restricted material pesticides in production agriculture.” Growing out of the passage of AB 617 Community Emissions Reduction Act in California, passed in 2017, farmworker safety advocates have long been urging an implementation strategy that provides notification of pesticide spraying. In late 2017, the California Air Resources Board (CARB) began implementation of AB 617, a bill enacted with the stated intent of addressing the air quality crisis in many communities of predominantly people of color who are disproportionately harmed by toxic chemicals. While the overall goal of the law is to reduce air pollution in these communities, farmworker advocates have sought to operationalize a pesticide spraying notification system to warn communities when nearby spraying is scheduled to take place. The idea behind notification programs and transparency in government is that it enables those potentially exposed to take precautionary measures to […]

(Beyond Pesticides, April 3, 2025) As highlighted by Beyond Pesticides in recent comments to the U.S. Environmental Protection Agency (EPA), chlorpyrifos (CPF) has been under scrutiny for decades due to associated adverse health effects, noted particularly in the extensive and consistent scientific evidence of neurotoxic dangers to children’s health. The latest research on CPF, published in Environmental Toxicology and Genes & Diseases, reveals additional threats to the immune system and male reproduction that are not captured in current EPA risk assessments of chlorpyrifos and raises serious health questions, given that residues are found throughout the food supply. CPF, a widely used organophosphate insecticide in agriculture, is a cholinesterase inhibitor that binds irreversibly to the active site of an essential enzyme for normal nerve impulse transmission, acetylcholine esterase (AChE), inactivating the enzyme. Many insecticides, including organophosphates and carbamates, target AChE, causing them to be highly toxic to both insects and mammals that have this enzyme as a crucial part of their nervous systems. The history of chlorpyrifos exemplifies the failure of pesticide law and policy, as this chemical, among many others, not only has direct adverse health effects but is contributing to the climate crisis, biodiversity collapse, and disproportionate levels of […]

(Beyond Pesticides, April 2, 2025) In examining prenatal residential proximity of documented pesticide spraying in California to the menstrual cycle characteristics of 273 Latina adolescents, researchers report in the American Journal of Epidemiology a positive association between exposure to the insecticide methomyl and heavy bleeding. Other pesticides appear to influence menstrual symptoms as well. “Adolescents’ menstrual cycle characteristics can be ‘vital signs’ of health and impact quality of life,” the authors share. They continue, “To our knowledge, this is the first study to examine the association between prenatal pesticide exposure and menstrual outcomes in adolescents of any demographic group.” Menstrual cycle characteristics, such as dysmenorrhea (painful or uncomfortable menstrual cramps), irregularity, and heavy menstrual bleeding, can also be indicators of underlying health conditions, including endometriosis, polycystic ovary syndrome (PCOS), thyroid dysfunction, and bleeding disorders. By associating the pesticide exposure of mothers during pregnancy to impacts on their children, the researchers highlight important health risks for women and young girls that are often disregarded. “The prenatal period is a critical period of reproductive development that may be particularly sensitive to endocrine disruption,” the researchers share. As previously reported by Beyond Pesticides, endocrine-disrupting chemicals are any synthetic or natural compounds that hinder […]

(Beyond Pesticides, March 18, 2025) The November 2024 press release by the U.S. Environmental Protection Agency (EPA) for its Rodenticide Strategy includes the final biological evaluation (BE) of 11 rodenticides. Prior to the finalization of the BE, Beyond Pesticides commented to EPA’s Office of Pesticide Programs in early 2024, disagreeing with the categorical no effect (NE) determinations for all freshwater and marine fish, aquatic mammals, aquatic amphibians, aquatic reptiles, and aquatic invertebrates. (See related Daily News and Action of the Week.) The latest scientific literature highlights the impacts of rodenticides on nontarget organisms, including aquatic organisms that the agency failed to evaluate due to harm that was, as EPA says, “not reasonably certain to occur.” Many rodenticides, intended to target rats, mice, squirrels, nutria, and more, are anticoagulants and stop normal blood clotting. Active ingredients in these pesticides can include bromadiolone, chlorophacinone, difethialone, brodifacoum, and warfarin. Anticoagulant rodenticides (ARs), contrary to the agency’s assertions, can be transported to aquatic ecosystems, including both freshwater and marine environments. As mentioned in Beyond Pesticides’ comments, ARs have been detected in raw and treated wastewater, sewage sludge, estuarine sediments, suspended particulate matter, and liver tissues of sampled fish, demonstrating that the aquatic environment experiences […]

(Beyond Pesticides, March 17, 2025) When Secretary of Health and Human Services Robert F. Kennedy, Jr. announced last week that he is directing the U.S. Food and Drug Administration (FDA) to explore rulemaking to review substances in food affirmed by the food companies to be Generally Recognized as Safe (GRAS), he said he is “committed to promoting radical transparency to make sure all Americans know what is in their food.” The issue of independent review of the food industry’s GRAS declarations has long been the subject of critiques raising public health concerns. As this issue emerged, on another food safety issue, Beyond Pesticides is asking  FDA to use its broad authority under the Federal Food, Drug, and Cosmetic Act to “ensur(e) that human foods and animal feeds are safe” from residues of pesticide mixtures, in light of new troubling scientific data. Under various memoranda of understanding between FDA, the U.S. Environmental Protection Agency (EPA), and the U.S. Department of Agriculture (USDA) going back decades, FDA could consult with EPA on food safety issues ignored by the agency, including  recent data published in Pesticide Biochemistry and Physiology, which “suggest that combined [pesticide] exposure may further amplify the toxicity and compromise the intestinal […]

(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 […]

(Beyond Pesticides, March 12, 2025) Earthjustice filed a lawsuit with the U.S. Department of Agriculture (USDA), challenging the Department’s alleged illegal purging of datasets, resources, and pertinent information that organic farmers rely on to carry out their operations, according to the complaint filed on February 24, 2025. The deletion of public data compounds the numerous threats facing organic and regenerative organic farmers across the nation. The uncertainty associated with the starting and then stopping of tariffs has led to surges in costs and supply chain challenges. Meanwhile, core organic programs, including the Organic Certification Cost Share Program, Organic Data Initiative, and Organic Certification Trade and Tracking Program, remain unfunded, leaving huge uncertainties for the organic sector moving forward. The administration has canceled the spring meeting of the National Organic Standards Board (NOSB), the Congressionally-mandated board established to guide the setting of standards and materials on the National List of Allowed and Prohibited Substances. In theory, organic farmers and public and environmental health advocates align with some of the stated objectives of the Make America Healthy Again Commission (MAHA), established by executive order on February 13, 2025. MAHA’s stated efforts to “drastically lower….chronic disease rates and end…childhood chronic disease” would be […]

(Beyond Pesticides, March 10, 2025) Following International Women’s Day, celebrated on March 8, 2025, the poignant findings on women, gender, and hazardous substances in a United Nations report raise critical issues of concern and cause for urgent action to phase out petrochemicals. The Report of the Special Rapporteur on the implications for human rights of the environmentally sound management and disposal of hazardous substances and wastes, by Marcos Orellana, was delivered to the 79th Session of the United Nations General Assembly in July 2024. Excerpts from the report follow: “Women make up roughly 60 to 70 per cent of the agricultural labour force in developing countries where pesticides and pesticide handling are especially poorly regulated. In Zambia, for example, two thirds of the labour force is engaged in agriculture, and 78 per cent are women farmers and peasants. Women there play a significant role in pesticide application, often without any or adequate personal protective equipment, especially during activities such as weeding, harvesting, and washing pesticide-laden clothes.” “In higher-income countries, women who do agricultural work are often poor and/or migrants; pesticides are one of many dimensions of marginalization and damage to their well-being. The European agriculture sector uses many seasonal and […]

(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 […]

(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 […]
