Review Identifies Regulatory Deficiencies in the Risk Assessments of Chemical Mixtures Including Pesticides

(Beyond Pesticides, April 28, 2026) In Chemical Research in Toxicology, researchers from the Universitat Rovira i Virgili in Catalonia, Spain highlight the threats to human and environmental health with “combined exposures to multiple chemical toxicants, including industrial chemicals, heavy metals, pesticides, endocrine-disrupting chemicals (EDCs), and per- and polyfluoroalkyl substances (PFAS).” As these compounds are encountered in mixtures in real-world settings, the resulting interaction can have additive or synergistic effects that risk assessments fail to adequately capture. As the authors point out: “This leads to a systematic underestimation of health risks, particularly for vulnerable populations. Despite robust evidence on mixture toxicity, major regulatory frameworks such as the U.S. Toxic Substances Control Act (TSCA) and the EU’s [European Union] REACH program continue to assess chemicals in isolation.” Importance and Background Environmental toxicants are ubiquitous throughout nature and within all organisms. In humans, these compounds can accumulate, referred to as ‘Body Burden’, which encompasses numerous chemicals such as pesticide mixtures. “Critically, organisms are rarely exposed to a single chemical in isolation,” the researchers note. “Rather, they continuously encounter complex mixtures of contaminants whose combined effects may differ substantially from those predicted by examining each substance individually.” As the authors explain, regulatory agencies underestimate […]

Review Highlights Threats to Health and the Environment from Pesticide Contamination in the Atmosphere

(Beyond Pesticides, April 24, 2026) In a review of scientific literature documenting pesticide contamination in the atmosphere, international researchers find human and ecosystem exposure even in remote and distant areas. As published in the Journal of Hazardous Materials, the authors state: “Atmospheric transport of pesticides is a globally significant yet widely underestimated driver of human and ecological exposure, with contamination documented far beyond treated fields. This review provides a novel integrated synthesis, bridging emission pathways, atmospheric transformation processes, monitoring evidence, model limitations, and regulatory gaps to deliver a comprehensive understanding of the fate and impacts of pesticides in the atmosphere.” In analyzing the current knowledge on pesticide emissions, through both drift and volatilization (process where a solid or liquid converts into a gas or vapor), the researchers highlight “the widespread detection of both current-use and banned pesticides in environmental matrices far from their application,” along with the resulting implications for human health and environmental health. As the current risk assessment framework “fails to adequately address the perturbations caused by the atmospheric transport of pesticides,” the urgent need to transition away from chemical-intensive practices grows stronger. Background While this review highlights regulatory gaps in the European Union (EU), the cited scientific […]

Pick Your Poison: Pesticide Contamination in Cannabis Reveals Longstanding Gaps in Safety

(Beyond Pesticides, April 1, 2026) Researchers at the University of Washington and members of the Washington State Liquor and Cannabis Board published a commentary piece in Clinical Therapeutics highlighting the growing inadequacy of state-level regulatory safeguards for pesticide contamination of cannabis products. The Environmental Protection Agency (EPA) is unable to assess pesticide residues, nor is it permitted to set tolerance limits under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), because, according to the Controlled Substances Act (CSA), cannabis is a Schedule 1 narcotic, meaning there is “no accepted medical use.” As a result, EPA cannot conduct a full assessment of pesticide exposure associated with inhalation, ingestion, and dermal (skin) adsorption. There is an ongoing rescheduling process that was proposed in 2024 and followed up with an executive order in late 2025 to transition cannabis toward Schedule III status, suggesting that there would be an opening for EPA to promulgate rulemaking to support state-level regulations if it were to move forward. An analysis of active legislation in state legislatures for the 2026 session highlights the concerns—at least 14 states (including Connecticut, California, Georgia, Hawai’i, Illinois, Iowa, Kansas, Kentucky, Maine, New Hampshire, Oklahoma, Virginia, West Virginia, and Wisconsin) had bills to […]

Groups Decry Chemical Industry Supreme Court Argument that Product Users Can Be Harmed But Not Warned

(Beyond Pesticides, March 31, 2026) A statement decrying chemical company secrecy was released today by over 200 grassroots, health, farm, farmworker, environmental, and consumer groups, socially responsible corporations, over 340 citizens from 46 states, and international partners. The statement, released before the U.S. Supreme Court tomorrow reaches the final deadline for submission of amicus briefs in a case in which Bayer/Monsanto argues, with support of the Trump administration, that it should not be required to disclose on its product labels the potential hazards of its pesticide products. Oral arguments in the case will be heard on April 27, with a decision anticipated in June. Decades of law have upheld the legal argument that chemical companies are liable for their failure to warn users of their pesticides about the harm that they could cause. Bayer/Monsanto is attempting to reverse years of case law and billions of dollars in jury verdicts and future cases in which the company has been held liable for causing cancer but not warning product users. See statement, Stop Chemical Company Secrecy of Pesticide Product Hazards. Chemical Industry State Campaign The chemical industry last year launched a multi-pronged campaign to establish immunity from litigation by those who have […]

Pesticide Exposure Again Linked to Neurotoxic Effects in Humans and Wildlife in Comprehensive Review

(Beyond Pesticides, March 12, 2026) The science connecting pesticide exposure to neurotoxicity continues to mount. A study in Discover Toxicology highlights neurotoxic pollutants as significant environmental threats, showcasing the adverse impacts on vertebrates’ neurological health from pesticides, including organophosphates, carbamates, and organochlorines. “These substances disrupt normal neurophysiological functions by impairing neurotransmission, generating oxidative stress, provoking neuroinflammation, and initiating neuronal cell death,” the authors say. They continue, “Such disturbances are linked to cognitive deficits, motor impairments, and abnormal neural development.” Neurological conditions can manifest as headaches, muscle weakness, tremors, paralysis, coordination challenges, vision loss, hallucinations, vertigo, seizures, memory loss, slurred speech, trouble breathing with minimal exertion, and more. The range of adverse effects from low-dose, long-term exposure and low-dose (or subchronic) exposure during developmental phases of life raises serious questions about the adequacy of the regulatory review of pesticides, which focuses on acute high and lethal dose exposure. One study on the neurotoxicity of pesticides, published in Chemosphere, concludes, “New regulatory and preventive measures to mitigate the neurotoxic effects of pesticides are needed.” (See also Daily News.) Even at low concentration, chronic exposure to pesticides and other environmental contaminants “poses serious ecological and health concerns” that occur as these chemicals “bioaccumulate […]

Monsanto Brief Introduced as U.S. Supreme Court Considers Liability Immunity for Pesticide Manufacturers

(Beyond Pesticides, March 11, 2026) The Monsanto Company, founded in 1901 and acquired by the multinational corporation Bayer AG in 2018, submitted its opening brief to the Supreme Court of the U.S. (SCOTUS) last month, seeking liability immunity from lawsuits filed by product users who have been harmed but not warned about potential product hazards. The question before SCOTUS is: “Whether the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. 136 et seq., preempts a state-law failure-to-warn claim concerning a pesticide registered by the U.S. Environmental Protection Agency (EPA), where EPA has determined that a particular warning is not required and the warning cannot be added to a product label without EPA approval.” If successful, the Court would be overturning (reversing) its 2005 decision in Bates v. Dow Agrosciences, 544 U.S. 431, which upheld EPA and state registration of pesticides as a floor of protection, without releasing manufacturers of the responsibility to warn for potential harm that is not required by EPA. Pesticide manufacturers propose the text for their product labels and EPA ensures compliance with its minimum requirements, which does not preclude them from disclosing potential adverse effects they know of or should have known. The Missouri case before the Supreme Court, Durnell v. Monsanto, on the cancer causing effects of the weed killer glyphosate (RoundupTM) resulted in a jury verdict (in 2023) of $1.25 million and the total number of jury verdicts and settlements may amount to over $10 billion in liability if […]

Farm Bill Strips Protections from Pesticides for Farmers, Consumers, and the Environment

(Beyond Pesticides, March 6, 2026) The Farm Bill—the Farm, Food, and National Security Act of 2026, H.R. 7567—reported out of the Agriculture Committee in the U.S. House of Representatives yesterday strips environmental and public health protections from pesticides, reversing over 90 years of environmental laws adopted by Congress to protect farmers, consumers, and the environment that stretch back to the first Farm Bill in 1933. The Committee rejected the Protect Our Health Amendment, sponsored by Rep. Chellie Pingree (D-ME), which would have ensured that the final bill maintain three core safeguards in current law: (i) Judicial review of chemical manufacturers†failure to warn about pesticide hazards; (ii) Democratic right of local governments in coordination with states to protect residents from pesticide use; and, (iii) Local site-specific action to ensure protection—the safety of air, water, and land from pesticides under numerous environmental statutes. All Republicans and one Democrat (Rep. Adam Gray, D-CA) on the Committee blocked the Pingree amendment. The Agriculture Committee bill adversely affects a wide range of social and conservation issues, including the protection of family farms, food security, environmental and public health, local and state authority, and judicial review, according to a cross-section of groups representing these interests.

Report Describes Complex Cumulative Risk Assessment Proposal to Implement California Law

(Beyond Pesticides, February 12, 2026) Editor’s Note. This is a piece about improving risk assessments and a proposal that could offer a more realistic characterization of the harm associated with the complexities of pesticide exposure. Beyond Pesticides notes that risk assessment methodology, unless it is considered in the context of a rigorous alternatives assessment, begins with the mostly false assumption that petrochemical pesticides are needed (or are essential) to achieve cost-effective pest management, agricultural productivity and profitability, and quality of life, when, in fact, this is not the case. Therefore, improved risk calculations—as the article being reviewed here proposes—while important to characterizing the harm and the unknown adverse effects associated with pesticide use, still impose some level of harm deemed by the government to be acceptable. Even worse, the adverse effects of exposure cannot be fully characterized because of uncertainties or a lack of data on harmful endpoints, as is the case currently with endocrine-disrupting pesticides not fully evaluated by the U.S. Environmental Protection Agency (EPA), California’s Department of Pesticide Regulation (DPR), or other regulatory bodies. These pesticides are known to induce cancer, reproductive harm, infertility, biodiversity decline, and other life-threatening, often multigenerational, effects. The authors do recognize the serious […]

U.S. Abandons International Collaboration on Existential Health Challenges at Time When Most Needed

(Beyond Pesticides, February 6, 2026) The United States, under Donald Trump’s direction, has withdrawn from 66 international organizations, the most important for health being the United Nations’ World Health Organization (WHO) and the Intergovernmental Panel on Climate Change. International organizations committed to the application of the best available science and policy development via consultation and consensus serve as a vital check against rampant personal and industry nest-feathering at the expense of global health. The Trump administration has removed this check while expanding his and his associates’ self-dealing and dismissing the critical interactions of crises such as climate change and synthetic chemicals. Although Trump announced this move on inauguration day last year, the completion of the process last week puts the stamp of finality on his total abandonment of public health. This in turn threatens the collapse of WHO—and even the U.N.—altogether, which has wide implications for agriculture, particularly pesticide policies, climate action (and inaction), and infectious disease monitoring, including vaccines and pandemic prevention. [See commentary: On Public and Environmental Health and Worldwide Collaboration.] Other U.N. environmental, health, and agricultural organizations on the list are groups focused on forest degradation, freshwater and oceans, mining, minerals, metals, and sustainable development, biodiversity, and ecosystem […]

Amid Immediate and Chronic Health and Environmental Effects, Drift-Prone Herbicide Slated for Reapproval

[Update on February 9, 2026: In a press release on Friday, February 6, titled “EPA Implements Strongest Protections in Agency History for Over-the-Top Dicamba Use on Cotton and Soybeans for Next Two Growing Seasons,” the U.S. Environmental Protection Agency (EPA) continues to ignore the wide body of science that documents harms from dicamba, as well as the viability of alternative methods, in establishing what the agency is boasting are “the strongest protections in agency history for over-the-top (OTT) dicamba application on dicamba-tolerant cotton and soybean crops” as a direct response to the “strong advocacy of America’s cotton and soybean farmers.” These so-called “strong protections” are described as a way to ensure farmers can access the tools they “need” while also protecting the environment from dicamba’s harmful drift. In using “gold-standard science and radical transparency,” EPA created new label restrictions for the next two growing seasons that include “cutting the amount of dicamba that can be used annually in half, doubling required safety agents, requiring conservation practices to protect endangered species, and restricting applications during high temperatures when exposure and volatility risks increase.” Relying on unenforceable label restrictions and mitigation measures, however, fails to adequately protect health and the environment.

Congress Members Call for Growing Organic, as Regulatory Failures to Ensure Protection from Pesticides Mount

(Beyond Pesticides, January 26, 2026) As a mounting number of scientific studies link pesticides to adverse health and environmental effects not evaluated under the U.S. Environmental Protection Agency’s (EPA) pesticide registration program, members of Congress are planning to introduce legislation that elevates the organic solution. To this end, Beyond Pesticides and allies are calling on U.S. Representatives and Senators to become a cosponsor of the Opportunities in Organic Act, which is expected to be reintroduced in early 2026 by U.S. Senator Peter Welch and U.S. Representative Jimmy Panetta. In its Pesticide-Induced Diseases Database, Beyond Pesticides critiques studies associating pesticides with serious adverse effects ignored by the regulatory process, including multigenerational effects, chronic low-dose exposure and aging, impacts on fertility dysfunction, synergistic effects associated with mixtures, and endocrine disrupting effects, among others. At the same time, there is a growing body of evidence demonstrating the environmental, health, climate, and economic benefits of organic agriculture.  With the weakening of pesticide regulation, the organic alternative has become especially important, according to health and environmental advocates. However, the organic growth needed to reverse the looming health and environmental crises will not be achieved without a societal investment in organic transition, they say. Although consumption of organic food continues to grow in the U.S., domestic production lags behind. The Opportunities in […]

Retraction of Journal Article on Weed Killer Glyphosate (Roundup™) Safety Sparks Call for Oversight Hearings

(Beyond Pesticides, January 12, 2026) With a pattern of chemical industry deception of independent scientific review, and the recent retraction of an influential Monsanto ghostwritten article (April 2000) on the weed killer glyphosate (Roundup™), Beyond Pesticides and its network are calling for oversight hearings in Congress. At issue is the reliance of the U.S. Environmental Protection Agency (EPA) on industry data and agency collusion with chemical manufacturers on its decisions. Beyond Pesticides is questioning the underlying reliability of the data, in addition to limitations of the regulatory review process in meeting its statutory duty to protect health and the environment. In addition to the deception, key underlying deficiencies are EPA’s failure to evaluate endocrine disrupting pesticides and synergistic effects of chemical mixtures. Given these deficiencies and the cost effectiveness of organic land management and crop production Beyond Pesticides is asking Congress to hold oversight hearings to determine how EPA can eliminate the use of toxic pesticides that are no longer needed to grow food or manage landscapes cost-effectively.  Critically, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and EPA’s pesticide program allow toxic chemicals to be dispersed, resulting in widespread negative impacts, without regard for the availability of cost-effective and profitable alternatives that are eco-sensitive and health protective. Consideration of the essentiality of synthetic substance […]

Scientific Deception by Monsanto/Bayer on Display with Retraction of Landmark Glyphosate Safety Study

(Beyond Pesticides, December 12, 2025) A study concluding that the weed killer glyphosate did not cause cancer was retracted last week after it was revealed in lawsuit documents that the authors did not disclose their relationship with Monsanto/Bayer. The editor-and-chief, Martin van den Berg, PhD of Regulatory Toxicology and Pharmacology, which published the article 25 years ago, wrote in the journal, “Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors.”  The study, titled “Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans” and coauthored by three researchers in New York, The Netherlands, and Canada, was referred to as a “Landmark glyphosate safety study” in a recent article by U.S. Right to Know.   While this retraction not only sheds light on Monsanto’s influence through ghostwriting, it adds to the wide body of evidence regarding the regulatory deficiencies currently in place. The revelation is a reminder of related incidents in which Monsanto (Bayer) and other companies have wielded excessive influence at the U.S. Environmental Protection Agency (EPA), undermining the integrity of the science needed to inform the regulatory decisions that safeguard health and the environment. (See Daily News Corruption Problems Persist at EPA.)  EPA Deficiencies  In addition to the initial registration process, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that EPA conduct a registration review of all pesticide […]

Trump Administration to U.S. Supreme Court: Pesticide Companies Cannot Be Sued for Failing to Disclose Hazards

(Beyond Pesticides, December 11, 2025) In an amicus brief published on December 1, 2025, the Office of the Solicitor General (SG) and the White House are calling on the Supreme Court of the United States (SCOTUS) to grant certiorari on Bayer’s petition to shield chemical companies that fail to warn people about the potential hazards of their pesticide products. The U.S. Solicitor General D. John Sauer (former Solicitor General of Missouri, home to Bayer-Monsanto’s U.S. headquarters), in siding with the Germany-based, multinational pesticide corporation, calls for SCOTUS to take on the case, which could lead to a prohibition on state-level failure-to-warn claims based on the arguments laid out in the amicus brief. This move sets the stage for SCOTUS to undermine the main legal argument used to hold pesticide corporations accountable for their harmful products, sending Bayer’s stock price to skyrocket 12 percentage points between December 2 and December 3 after the decision was made public. As of May 2025, Bayer has already paid at least 10 billion dollars in jury verdicts and settlements to cancer victims who have attributed their diagnoses to the use of Bayer/Monsanto’s glyphosate-based Roundup weed killer products, according to Lawsuit Information Center. Two previous petitions […]

Weak Recovery of Bird Species after Neonic Ban with Exceptions in France, Persistence Cited

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.    “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,” the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.” Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]

At Odds with Intl Regulatory Bodies, EPA Defines Away PFAS Problem, Allows Widespread Contamination

(Beyond Pesticides, December 4, 2025) In a news release last week on November 26, 2025, the U.S. Environmental Protection Agency (EPA) “issued a comprehensive fact-check addressing dangerous misinformation circulating about EPA’s recent pesticide approvals” that, according to health and environmental advocates, continues to deceive the public about the true risks for health and the environment from petrochemical pesticides including, but not limited to, per- and polyfluoroalkyl substances (PFAS). Also published on November 26, coverage titled The EPA Is Embracing PFAS Pesticides. These Are The Health Risks in Time further highlights EPA’s deficiencies and the threats of PFAS, which Beyond Pesticides has extensively covered. (See here and here.)  The controversy erupted as a result of EPA’s latest proposal to allow a new fluorinated pesticide to the list of four other similar compounds now widely available for use in homes and gardens, buildings, and agriculture. The newest pesticide proposed for EPA registration, epyrifenacil (agricultural weed killer), joins cyclobutrifluram (soil fungicide/nematicide), isocycloseram (household and agricultural insecticide), diflufenican (lawn and agricultural weed killer), and trifludimoxazin (agricultural weed killer), making a total of five PFAS pesticide proposals this year that have been associated with national and worldwide contamination of food, land, and water. Two of these, cyclobutrifluram and isocycloseram, have been approved. “Instead of constraining the use of fluorinated pesticides—persistent and highly toxic […]

Report on Weed Killer Paraquat Identifies True Hazard Costs from Manufacturing to Use

(Beyond Pesticides, November 6, 2025) The report, Designed to Kill: Who Profits from Paraquat, and accompanying interactive storymap, unpacks the supply chain of the infamous herbicide paraquat and underscores the true costs of pesticide products, from manufacturing to use in the fields. This report is part of a larger initiative, the Pesticide Mapping Project—“a collaborative research series that illustrates the health and climate harms of pesticides across their toxic lifecycle: including fossil fuel extraction, manufacturing, international trade, and application on vast areas of U.S. land.” Top Highlights This report highlights, among other notable points, “that every stage of the paraquat supply chain—which spans the globe—emits greenhouse gases and toxic air pollutants.” With SinoChem as the lead producer and player in the paraquat market, the Chinese government-owned pesticide company’s supply chain “includes fossil fuel extraction in Equatorial Guinea and Saudi Arabia, chemical manufacturing in India, Germany, and the United Kingdom, international chemical shipping, and final formulation and distribution in the United States.” Paraquat is not currently manufactured in the U.S., accounting for imports of “between 40 and 156 million pounds of paraquat each year, according to the last eight years of pesticide import records available from the private database.” Despite the […]

Dietary Pesticide Exposure Study Stresses Need for More Accurate Assessment

(Beyond Pesticides, October 21, 2025) A study, published in International Journal of Hygiene and Environmental Health, calculates cumulative dietary pesticide exposure and finds a significant positive association between pesticide residues in food and urine when analyzing over 40 produce types. The research uses data for 1,837 individuals from the 2015–2016 National Health and Nutrition Examination Survey (NHANES) and compares them to biomonitoring samples of the participants. According to the researchers, “Here we show that consumption of fruits and vegetables, weighted by pesticide load, is associated with increasing levels of urinary pesticide biomarkers.” They continue, “When excluding potatoes, consumption of fruits and vegetables weighted by pesticide contamination was associated with higher levels of urinary pesticide biomarkers for organophosphate, pyrethroid, and neonicotinoid insecticides.” The NHANES data is derived from a national biomonitoring survey from the U.S. Centers for Disease Control and Prevention (CDC), which collects information about consumption of fruits and vegetables as well as urine samples. Background As the study authors explain: “Hundreds of millions of pounds of synthetic pesticide active ingredients are used every year in the United States, and pesticide exposure can occur through food, drinking water, residential proximity to agricultural spraying, household pesticide use, and occupational use.

PFAS, Pesticide, Pharmaceuticals, and Heavy Metals Found in Backyard Eggs Underscore Toxic Threat

(Beyond Pesticides, September 25, 2025) Reinforcing numerous studies’ findings of widespread environmental contamination with PFAS (per- and polyfluoroalkyl substances), heavy metals, pesticide metabolites, and pharmaceuticals, researchers detected the chemicals in noncommercial backyard eggs laid in Greece, according to a study published in Science of The Total Environment. The researchers found that “[o]nly 9 out of 17 samples were compliant to the limit….set by the [European Union] for the sum of PFHxS [perfluorohexanesulfonic acid], PFOS [perfluorooctanesulfonic acid], PFOA [perfluorooctanoic acid], and PFNA [perfluorononanoic acid].” They continue: “[A]s regards PFOS, PFHxS, and PFNA, seven, six and one out of 17 samples, respectively, were above the ML (maximum limit) as set by the EU.” With current regulatory standards focused on evaluating exposure to individual chemicals and, in some instances, cumulative risk associated with chemicals that have a common mechanism of effect, this study points out the importance of looking at mixtures of chemicals and the potential synergistic effects. There are some fluorinated pesticides defined as PFAS due to their molecular structure and high toxicity, which makes the chemicals highly persistent in the environment. Center for Food Safety, Center for Biological Diversity, and Public Employees for Environmental Responsibility reviewed the full list of active […]

Study of Earthworms Finds Fluorinated Pesticides Threaten Soil Ecosystems

(Beyond Pesticides, September 18, 2025) Published in Environmental Toxicology and Pharmacology, a study of earthworms (Eisenia fetida) evaluates the toxicity of environmentally relevant levels of three fluorinated pesticides (fluxapyroxad, fluopyram, and bixafen) through a 56-day soil exposure experiment. The dose- and time-dependent results reveal that effects on growth and reproduction occur at elevated concentrations, with weight loss and reduced offspring occurring from energy depletion and reproductive organ damage. Other implications escalate with concentration as well, including antioxidant system failure and DNA damage. As the authors summarize, “These findings highlight the mechanisms of fluorine-containing pesticide toxicity in earthworms, emphasizing their potential to disrupt soil ecosystems.” Fluorine-containing pesticides are widely used in agriculture, yet the chronic effects on soil and soil organisms are not fully considered in regulatory review. Research comparing the similarities and differences in the impacts on nontarget organisms from fluorinated pesticides is lacking, with the current study beginning to address the urgent need to close this gap. “Data indicate that among more than 100 newly developed pesticides, fluorine-containing pesticides constitute nearly half, making them a focal point in the development of the global pesticide industry,” the researchers state. As representatives of the fluorinated pesticides class, particularly succinate dehydrogenase inhibitors […]

EPA Webinar Today on New Self-Directed Pesticide Restrictions, Criticized as Lacking Accountability

(Beyond Pesticides, September 16, 2025) As reported in the Daily News on August 28, the U.S. Environmental Protection Agency (EPA) announced that it “will hold a public webinar [today], September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can be used to protect endangered species from pesticides.” This follows closely behind an earlier announcement of a newly released Pesticide App for Label Mitigations (PALM) mobile tool to assist in implementing these mitigation measures. Despite boasting that the PALM tool is a “one-stop shop” for farmers to use EPA’s mitigation menu, which the agency claims helps to protect nontarget species, environmental critics say that self-directed mitigation without a rigorous reporting and enforcement apparatus fails to meet the level of protection that is necessary under the Endangered Species Act (ESA). As Beyond Pesticides has often reported, mitigation measures are not enforced through recordkeeping, inspections, and certification, and require no accountability from farmers and pesticide applicators. At the same time, EPA assumes compliance with mitigation measures as the basis for meeting statutory standards of reasonable risk from harmful chemicals, despite documented health and environmental harm. As a Daily News article earlier this […]

MAHA Strategy Report Backs Off Pesticides After Defining Serious Threat in Earlier Assessment

(Beyond Pesticides, September 10, 2025) After being criticized by the chemical industry and allied agribusiness and service industry groups on the Make America Healthy Again (MAHA) report in May, the strategy document, released yesterday, has tamped down efforts to reform government programs that regulate pesticides. There are no specific recommendations on improving the regulation of pesticides. Rather, the strategy appears to embrace business-as-usual and could even ramp up government efforts to tout the need for pesticides and claims that current regulatory reviews are effective and comprehensive. In a section of the strategy entitled “Increasing Public Awareness and Knowledge,” the document says: “EPA, partnering with food and agricultural stakeholders, will work to ensure that the public has awareness and confidence in EPA’s pesticide robust review procedures and how that relates to the limiting of risk for users and the general public and informs continual improvement.” This is at odds with the earlier MAHA assessment report which identified pesticides as substances of concern that, citing deficiencies in chemical reviews, “may be neglecting potential synergistic effects and cumulative burdens, thereby missing opportunities to translate cumulative risk assessment into the clinical environment in meaningful ways.” While the earlier report, Make Our Children Healthy Again: Assessment, […]

Grassroots Uprising in France Stymies Industry Effort To Bring Back Bee-Killing Insecticide

(Beyond Pesticides, September 2, 2025) It did not go without notice to U.S. grassroots environmental and public health advocates that earlier this month, over two million people in France signed a “first of its kind” petition that ultimately prevented the overturning of the country’s ban on bee-killing neonicotinoid insecticides. The action was widely covered in France, including in Le Monde. This uprising, organized by 23-year-old French master’s student Eleonore Pattery, emphasizes the importance of individuals in communities mobilizing people to protect the planet from pesticides that are having a devastating adverse effect on health and the environment. The grassroots push in France taps into a deep public concern about health and the environment that is emblematic of the level of public engagement needed to thwart the high level of chemical industry, agribusiness, and allied corporate influence that undermines basic protections. Industry interests have long been embedded in federal environmental and public health laws. For example, federal and state pesticide laws (the Federal Insecticide, Fungicide, and Rodenticide Act and similar state laws) allow widespread exposure to toxic chemicals despite the availability of nontoxic alternatives that are both efficacious and cost-effective. Without public engagement, as seen in France, significant improvements in law are constantly […]
