(Beyond Pesticides, July 15, 2026) Researchers at the U.S. Geological Survey and Portland and Oregon State Universities, in a study reported in Marine Pollution Bulletin, find that pesticide exposure, including the herbicide atrazine and fungicide carbendazim, found in combination with the herbicide diuron in the environment, significantly impacts reproductive organ development in sea anemone (Anthopleura elegantissima), an important organism in the marine environment. “Sea anemone [is] any member of the invertebrate order Actiniaria (class Anthozoa, phylum Cnidaria), soft-bodied, primarily sedentary marine animals resembling flowers,” according to the Encyclopedia Britannica. According to the Convention on Biological Diversity, marine ecosystems store about 15 times more carbon emissions than terrestrial and soil ecosystems, while “oceans represent 95 percent of the [planet’s] biosphere.” Sea anemones are critical to protecting marine biodiversity by acting like microhabitats for small invertebrates such as opalescent nudibranchs and amphipods (beneficial crustaceans), serving as a food source for marine predators including sea stars and slugs, contributing to nutrient cycling by consuming passing crustaceans, among other benefits. (See here, here, here, and here.) For example, sea anemones provide protection and nutrients to Red Sea clownfish (Amphiprion bicinctus), and in return these fish offer a nature-based solution to ventilation, nitrogen, and carbon to the host and its […]

(Beyond Pesticides, July 14, 2026) “Around the world, children are born into a landscape where the doubling of pesticide use since 1990 has made these chemical substances ubiquitous in our soil and food,” said George Laryea-Adjei, PhD, UNICEF Global Program Division Director at the release of a new report—Underestimated and Overlooked: The Silent Impact of Pesticides on Children—published through an initiative of the United Nations Children’s Fund. He continued: “This report reveals a reality that is as urgent as it is ‘silent’: the profound impact of pesticides on the health and rights of the world’s most vulnerable citizens: children.” Many important truths in this report speak to the advocates, public health professionals, and concerned families across the globe who are researching, writing, teaching, and advocating for public health and environmental protection from toxic chemicals. This report identifies the failure of existing regulatory structures to ensure basic protections and cites scientific evidence, investigative reporting, and litigation, concluding that synthetic pesticides are inconsistent with sustainability and human health. Main Findings This report was coauthored by UNICEF staff and numerous stakeholder groups, including nonprofits, regulators, and academic institutions. The authors cite numerous data sources, including existing peer-reviewed science, World Health Organization (WHO) and […]

(Beyond Pesticides, July 8, 2026) This piece reports on yet additional new studies linking pesticides to breast cancer. Numerous recent reviews make it clear that pesticide exposure per se raises the risk of breast cancer, across a wide swath of pesticide types. One would think that with the body of science linking breast cancer with pesticide exposure, covered extensively by Daily News and the Pesticide-Induced Diseases Database, a scientific-based regulatory system would respond with a sense of urgency. And yet, that is not the case, as the U.S. Environmental Protection Agency (EPA) establishes “acceptable” rates of disease for individual chemicals or chemical families, but does not evaluate patterns of disease linked to multiple chemical exposure. And so, breast cancer is the most common cancer diagnosed in U.S. women, and women turn to medical intervention with drugs, early surgical intervention, and targeted radiation. Yet, the disease, principally associated with environmental rather than hereditary factors, and treatment cause severe disruption to the lives of women and their loved ones and are devastating to quality of life, while clinical responses can have adverse side effects. Many different pesticides affect cellular processes and structures, including alteration of genetic material, endocrine disruption, cell apoptosis, cell […]

(Beyond Pesticides, July 7, 2026) An analysis of scientific literature on pesticide contamination in infant formula reveals a public health issue of food safety for young children with potential lifelong impacts, as published in Environmental Toxicology and Pharmacology. Through a systematic review of research from 1975 to 2025, the authors, from the Department of Public Health and Infectious Diseases at the Sapienza University of Rome (Italy), find residues of pesticides that are linked to deleterious health impacts in infant formula, including insecticides such as organochlorines, organophosphates, pyrethroids, and neonicotinoids, and many herbicides. As the researchers share, the results highlight that: “[T]he contamination of infant formula does not concern a single class of substances, but manifests itself as a heterogeneous and simultaneous set of risks: pesticide residues, heavy metals, persistent environmental contaminants, mycotoxins and compounds released from packaging materials can coexist within the same product. This co-presence of contaminants of different origins confirms that the problem cannot be traced back to a single critical point, but reflects a complex supply chain context, in which each stage—from raw material production to industrial processes, storage and packaging—can contribute to the infant’s final exposure.” In confirming the presence of multiple pesticides within infant formula, […]

(Beyond Pesticides, June 30, 2026) A peer-reviewed article, published in Scientific Reports, focuses on the link between exposure to pesticide mixtures and Alzheimer’s Disease (AD) prevalence at the county-level across the United States. Alzheimer’s, a type of dementia that affects memory, thinking, and behavior, accounts for 60-80% of dementia cases. In conducting a novel cross-sectional analysis of data on pesticide application intensity and disease prevalence, the researchers, from the Medical University of South Carolina, are able to identify exposure clusters with significant associations to the occurrence of AD. The strongest positive associations, where AD prevalence increases as pesticide exposure increases, are “observed for a soil fumigation/nematicide system, an herbicide-dominant vegetation control regime, and a neuroactive insecticide system,” the authors note. These findings link pesticide mixtures to increased AD rates. (See the full PDF of the study here.) Study Importance and Background AD is a condition that gradually damages and destroys neurons in the brain, with disproportionate risks across the U.S. in certain geographical areas. (See here and here.) “These spatial patterns suggest that contextual and environmental determinants may contribute to disparities in dementia burden beyond established individual-level risk factors,” the researchers state. They continue, “Although AD dementia is the leading […]

(Beyond Pesticides, June 26, 2026) In a study published in Aquatic Toxicology, researchers in Brazil determined that the cumulative toxicity of acetamiprid (a neonicotinoid insecticide) and cyanobacteria (photosynthetic microbes that can produce toxins) has a synergistic effect on the health of aquatic water fleas, or Daphnia. The implications of these findings paint a troubling picture for broader aquatic food webs, as they serve as a bridge species across trophic levels, serving as a primary consumer of plants and algae while also providing energy to secondary and tertiary consumers up the chain. In this context, public health and environmental advocates argue that the combined toxicity of synthetic agrichemicals and naturally occurring toxins is often considered an externality (external cost) borne by the public rather than a direct cost of agricultural production or nonagricultural pest management. “When ecosystems are undermined, so are the economic systems that are relied upon to grow food,” says Max Sano, senior policy and coalitions associate at Beyond Pesticides. “The need for a wholesale transition to organic land management acknowledges this fundamental mismatch and seeks to account for these discrepancies, although policy must ensure that organic farmers have the resources they need to thrive.” Methodology and Main Findings […]

(Beyond Pesticides, June 17, 2026) A study out of Michigan State University reviews robust county-level data on pesticide use and breast cancer incidence rates, determining that there are “modest positive associations” in rural counties in the United States. The findings were published in Cancer Causes & Control. Public health and environmental advocates cite the proliferation of published, peer-reviewed research, like this new study, in support of a societal imperative to eliminate harmful agrichemicals and transition to organic practices. The U.S. and countries worldwide have standards for certified organic production, similar to the U.S. Organic Foods Production Act, that establish required practices, a national list of allowed and prohibited substances, public oversight and a stakeholder board with authority over allowed inputs, certification and inspection of on-farm practices, and an enforcement system to ensure standards compliance. There is limited federal investment in growing the organic sector, despite its productivity, profitability, and protection of healthy ecosystems. The study adds to the body of science that illustrates dramatic deficiencies in the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) under which the U.S. Environmental Protection Agency (EPA) and other federal statutes fall short in addressing the complex exposure patterns and adverse human and environmental effects, […]

(Beyond Pesticides, June 16, 2026) If there is one take-home message regarding reducing risk of childhood leukemias and brain cancers, it is to avoid exposure to pesticides during pregnancy—especially indoor insecticides such as flea and tick products, including DEET, household plant and commercial pesticide treatments, and proximity to pesticide applications in agriculture. A review by researchers at the University of Nebraska Medical Center and School of Natural Resources in Omaha considered 88 epidemiological papers published between 1980 and 2022 on pediatric cancer and environmental pesticide exposure and found elevated rates of pediatric cancers associated with pesticide exposure. The reviewers assessed the known associations between the risk of childhood leukemia and brain tumors and their or their parents’ exposure to pesticides, pesticide breakdown products and mixtures. They asked how important known exposures in drinking water were to the children’s risk, and whether genetics is a primary influence on cancer development. The researchers found that the risk of childhood brain tumors increased 1.5 times if pest control products were applied during the entire year before conception. High-grade glioma risk was four times higher when pesticides were applied during pregnancy. Prenatal exposure to flea and tick products raised risk, especially for children diagnosed under […]

(Beyond Pesticides, June 12, 2026) In a literature review published in Caspian Journal of Environmental Sciences, researchers assessed 27 peer-reviewed studies conducted between 2011 and 2025 on the adverse impacts of insecticides, including neonicotinoids, pyrethroids, organophosphates, chlorpyrifos, and fipronil. Across agricultural and suburban environments, pesticides were detected in the majority (88 percent) of samples. This review builds on the continuous flow of science that highlights the adverse impacts of synthetic pesticide dependency on ecosystems and wildlife that are essential to global biodiversity. Main Findings The researchers, based at a variety of research institutions in Jordan, Uzbekistan, Iraq, and India, refined their search to 27 studies after screening for geographic diversity and empirical robustness; for example, they excluded studies that did not include empirical data, relied solely on nonagricultural contexts, or only assessed exposure through urban wastewater exclusively. Toxicological data assessed include pesticide occurrence, toxicity, and biological responses. This literature review is not a meta-analysis, but rather a narrative synthesis of various findings. The main findings include: Documented Widespread Pesticide Occurrence. In the United States, based on data collected between 2013 and 2017, 88 percent of water samples contained pesticides, with a median of 18 compounds across all sites and 24 […]

(Beyond Pesticides, June 9, 2026) In a new literature review published in Florence Nightingale Journal of Nursing, researchers identify 10 peer-reviewed studies with a statistically significant relationship between pesticide exposure and declines in cognitive function among agricultural workers. The cognitive deficits adversely impact their daily functioning and safety on the job. These adverse impacts include disruptions to visual memory, attention, language speaking, and perceptual-motor function. Two of these studies specifically compare chemical-intensive and organic farmers, finding a relationship between less synthetic pesticide exposure and improved neurological and cognitive outcomes. While more data is needed to produce precise dose-response estimates by active ingredient/chemical mixture, the findings support a precautionary approach to pest management decisions and transitioning to organic land management, a trend that is increasing across the U.S. and worldwide. Main Findings The researchers identify 12 studies published between 2016 and 2023 that assessed pesticide impacts—“including insecticides, fungicides, herbicides, bactericides, rodenticides, and nematodes”—on various areas of cognitive function in agricultural workers, with 10 of those studies showing a statistically significant relationship. The main findings include: Two studies compare organic and chemical-intensive farmers, with one study focused on Costa Rica (Mora et al., 2022) and the other focused on the United States […]

(Beyond Pesticides, May 22, 2026) On Memorial Day, those who served and died in the armed forces are remembered for their ultimate sacrifice. And the victims of war are memorialized. Of critical note are the effects of war, that extend beyond the battlefield to those who return home or remain in the aftermath with post-traumatic stress disorder (PTSD) and ultimately take their lives by suicide, as well as those exposed to deadly chemicals that caused premature death. A 2022 study finds, “ VA [Veteran Affairs] patients with current or past diagnosis of PTSD have been found to have an unadjusted rate of 50.7 deaths by suicide per 100,000 person years of risk, compared to a rate of 13.2 in the general adult population.” This statistic can be evaluated in the context of a recent observational cohort study to be in print in August 2026 that focuses on exposure to toxic substances and suicidal thoughts and behaviors (STBs) through the analysis of data from 248,926 U.S. veterans enrolled in the Million Veteran Program (MVP). In comparing self-reported exposures to nine toxicants, including Agent Orange, chemical/biological weapons, anthrax vaccine, solvents/fuels, petroleum combustion products, lead, other metals, pesticides, and open-air burn pits, and […]

(Beyond Pesticides, May 18, 2026) As the studies continue to mount on the adverse effects of exposure to low levels of organophosphate insecticides, the calls for banning the chemicals are growing. Beyond Pesticides announced an action to “Tell Congress, FDA, and EPA that it is past time to stop the manufacture and use of all organophosphate pesticides, which damage the nervous system and brain at low levels.” There are alternatives to these chemicals that support productive and profitable farming operations. Defying the often-repeated claim that organophosphate pesticide effects occur only at high doses, a recent study by researchers at University of California, San Diego, and the Fundación Cimas del Ecuador in Quito, Ecuador, establishes for the first time the pattern of adverse developmental effects that low-level exposure has on healthy neurological and brain development in children. It is firmly established that widely used organophosphate pesticides in food production and other sites are severely toxic to a broad range of organisms. In what is known as their “classic” mechanism of action, they inhibit acetylcholinesterase (AChE), an enzyme that breaks down the neurotransmitter acetylcholine (ACh), particularly in neuromuscular junctions in the brain. Organophosphates are nerve agents, originally developed by the German company IG Farben (a […]

(Beyond Pesticides, May 8, 2026)  A study from Ecuador establishes for the first time the developmental pattern of nervous system toxicants—still widely used in agriculture, mosquito control, and landscaping—on healthy neurological and brain development in children. It is firmly established that widely used organophosphate pesticides are severely toxic to a broad range of organisms. In what’s known as their “classic” mechanism of action, they inhibit acetylcholinesterase (AChE), an enzyme that breaks down the neurotransmitter acetylcholine (ACh), particularly in neuromuscular junctions in the brain. Not enough AChE leads to a buildup of ACh in motor neurons. Organophosphates deplete AChE, and an acute dose can paralyze the heart and lung muscles, causing death. Chronic exposures are implicated in numerous neurodegenerative diseases, including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS). Beyond Pesticides’ Gateway on Pesticide Hazards and Safe Pest Management has detailed information on the organophosphates malathion, chlorpyrifos, diazinon, and others. Acetylcholine and AChE are vital biological chemicals conserved across the animal kingdom, from humans to insects and everything in between. Yet there is no established baseline for normal levels of ACh and AChE in humans. Comparing biomarkers of organochlorine exposure with normal values would be a major step forward in assessing the influence […]

(Beyond Pesticides, April 17, 2026) A comparative analysis published in The Lancet Planetary Health highlights the pervasiveness of pesticide pollution in organic and non-organic farms in Latin America (Costa Rica) and Africa (Uganda). While pesticides were detected in nearly all participating farmers, there is a significant relationship between lower biomarker concentrations (often correlating with less contamination) in urine samples of organic farmers relative to non-organic farmers. The researchers also identified that older farmers held higher herbicide and insecticide concentrations. This research builds on the preponderance of scientific evidence and lived experiences of agricultural communities across the globe, including the U.S., which documents nontarget contamination of food systems through air, water, and soil. In this context, Beyond Pesticides continues to advocate for a transition to organic land management practices. Methodology and Results “We collected urine samples from 601 conventional and organic smallholder farmers in Zarcero County, Costa Rica, and Wakiso District, Uganda, on two occasions during the primary spraying season,” the authors write in introducing their methodology. The researchers tested urine samples of small-scale farmers in Costa Rica and Uganda for a mix of pesticides that include a fungicide, herbicide and insecticides—mancozeb (ETU), 2,4-D, glyphosate, pyrethroid metabolites (3-PBA, DCCA), diazinon (IMPy), […]

(Beyond Pesticides, April 15, 2026) Researchers in the Czech Republic tested indoor dust across 116 homes and found that 93 percent of homes across urban and rural areas contained residue of at least one current-use pesticide (CUP). The study also found in every household residues of hexachlorobenzene (HCB) and pentachlorobenzene (PeCB), the breakdown products or byproducts of certain banned organochlorine pesticides (OCP). These compounds, as well as DDT metabolites DDE and DDD, were detected in more than half of the homes tested. Results in this study and previous research confirm that pesticides used outdoors find their way indoors, resulting in an exposure pattern that is not calculated when pesticides are registered and allowed on the market. The findings are published in Indoor Environments. These findings characterize the legacy of toxic pesticide exposure resulting from the proliferation of pesticides in the United States and around the world without a complete assessment of the chemicals’ residual activity and multigenerational adverse impacts on health. Based on the decades of peer-reviewed scientific literature on pesticide exposure and effects from across the globe, public health and environmental advocates warn that there is a continuation of this pattern of long-term effects associated with new pesticides linked […]

(Beyond Pesticides, April 13, 2026) There are numerous provisions—a package of provisions—in the U.S. House of Representatives Agriculture Committee Farm Bill, voted out on March 5, that seriously undermine protections of health and the environment from pesticides, according to public health and environmental advocates. In response, Beyond Pesticides and allies are calling on U.S. Representatives and Senators to reject the Farm Bill as passed out of the House Agriculture Committee and, instead, pass a one-year extension of current law to protect health and the environment. The Committee Farm Bill contains provisions that advocates and members of Congress call “poison pills” because any one of them is so far-reaching that they make the entire measure unacceptable. The package of amendments covers critical areas of protection that have been established over decades of Congressional action. While groups have called for major reforms, Beyond Pesticides, in an action recently released,  says, “Existing pesticide law forms the foundation on which improvements should be made, not backsliding to give the chemical industry free rein.” At stake, according to the group, are core safeguards that are seen as critical to the health of farmers, consumers and the environment—judicial review of chemical manufacturers’ failure to warn about pesticide […]

(Beyond Pesticides, April 9, 2026) “The routine use of common pesticides in agriculture is no longer an ethically viable option for sustainable food production,” according to a new review in Reproduction & Fertility by livestock researcher Whitney Payne, Ph.D. candidate, and Kelsey R. Pool, PhD, of the School of Agriculture and Environment at The University of Western Australia. They base their position on the endocrine-disrupting qualities of many pesticides. The authors describe endocrine-disrupting compounds (EDCs) as “an inescapable feature of modern life” and note that the “farming systems sit at the intersection of animal health, environmental integrity, and food production.” The review stresses the risks that EDCs pose to livestock, which are seriously understudied.   EDCs are introduced to cattle, sheep, chickens, goats, and other mammals via pesticides, plastics, and hormone treatments. Since humans consume livestock, the effects of EDCs on animals are not confined to animals themselves. Animal production systems illustrate how EDCs “can enter diverse food chains and ecosystems from a single source,” the authors write, being introduced by humans for one purpose and returning to affect livestock and humans indirectly through their long-term effects and breakdown products. While regulatory systems typically consider direct and indirect exposure pathways in […]

(Beyond Pesticides, April 8, 2026) Researchers at the U.S. Geological Survey (USGS) assessed pesticide and PFAS (per- and poly-fluoroalkyl substances) contamination in ten agricultural streams in the San Joaquin and Sacramento Valleys (Central Valley) in 2024, detecting 60 pesticides, synergists, and associated transformation products, including 12 fluorinated pesticides (Dithiopyr, Trifluralin, Fluridone, Oxyfluorfen, Penoxsulam, Flubendiamide, Bifenthrin, Flonicam, Indoxacarb, Cyhalothrin, Fluopyram, and Penthiopyrad) that meet the Organisation for Economic Cooperation and Development (OECD) definition of qualifying as PFAS. It is alarming to learn that “the OECD fluorinated pesticides were generally detected more frequently and at higher concentrations” relative to the 48 other compounds.  Relatedly, research finds products containing three of the detected pesticides (Methoxyfenozide, Imidacloprid, and Piperonyl Butoxide) associated with various PFAS, and according to the authors, there are a handful of active ingredients, such as the insecticide Methoxyfenozide and the fungicide Azoxystrobin, detected in 100 percent of collected samples. Their entire findings were published in Environmental Science & Technology Letters in March 2026. This research is critical to our understanding of the pervasiveness and ubiquity of multi-chemical pollution that impacts one of the most productive agricultural regions in the country. The regions encompassing these two valleys make up just one percent of total U.S. farmland, […]

(Beyond Pesticides, March 27, 2026) In a study of birth outcomes in Arizona, published in the Journal of Exposure Science & Environmental Epidemiology, researchers find that preconception and prenatal exposure to certain carbamates, organophosphates, and pyrethroids increases the risk of lower Apgar scores, a metric used to assess neonatal health at one minute and five minutes after birth. The results reveal that exposure to “several pesticide active ingredients at any point during preconception and/or pregnancy were associated with increased odds of low Apgar scores: the carbamates carbaryl and formetanate hydrochloride; the organophosphates diazinon and tribufos; and the pyrethroid cypermethrin.” This multi-institutional study, led by the University of Arizona with researchers from Harvard Chan School of Public Health and UCLA Fielding School of Public Health, provides novel insights, as it incorporates pesticide exposure over a 15-year period both before conception and throughout pregnancy. “To analyze associations of preconception and prenatal exposures to carbamate, organophosphate, and pyrethroid pesticide classes and 25 individual active ingredients with newborn Apgar scores to evaluate the relationship between these exposures and neonatal health,” the authors explain. They continue: “We used pesticide use registry and birth certificate data from 2006 to 2020, linked as part of the Arizona […]

(Beyond Pesticides, March 25, 2026) A literature review, published in Diseases, showcases the wide body of scientific literature linking pesticide exposure to liver disease through both apoptotic (programmed cell death without triggering inflammation) and non-apoptotic (regulated cell death with an inflammatory response) pathways. “In summary, our study confirms that pesticides carry significant health risks and sheds light on the underreported mechanisms that can drive their overall toxicity as a whole and hepatotoxicity [liver] in particular,” the researchers state.  In addition to analyzing the science on pesticide-induced apoptosis, the researchers “systematically illustrated an underappreciated mechanism of pesticide-induced overall and hepatic toxicity, i.e., the ability to induce non-apoptotic regulated cell death (RCD) pathways such as ferroptosis, necroptosis, and pyroptosis.” They continue, saying, “Importantly, our review stresses the contribution of pesticide-induced cell death modes to inflammation and immunity regulation in hepatic pathology.” Background Pesticides, as a comprehensive group, can be subdivided into classes based on their targets: rodenticides (rodents), herbicides (weeds), insecticides (insects), fungicides (fungi), nematicides (nematodes), acaricides (mites and ticks), and bactericides (bacteria). The use of these pesticides, particularly in agriculture, has skyrocketed over recent decades. As the authors state: “In 2019, the total pesticide market size was estimated to approach $85 […]

(Beyond Pesticides, March 24, 2026) Published in Environmental Pollution, study results in the floriculture region of Ecuador find detections of neonicotinoid insecticides (NNI) and the herbicide atrazine in drinking and irrigation water. The biomonitoring data reported in an earlier journal article in the same region found a total of 23 compounds used as herbicides, insecticides, and fungicides, their associated metabolites (breakdown products), which include organophosphates, pyrethroids, and neonicotinoids. (See Daily News here.) Researchers from the University of Iowa, University of California, San Diego State University, and Universidad de San Francisco in Quito, Ecuador, determined that 1 in 5 households (20.5%) have detectable levels of one or more neonicotinoids in drinking water samples surrounding floricultural agricultural operations. This builds on previous research underscoring the nontarget pesticidal effects in communities near agricultural operations where the chemicals drift through the air and move into soil and water. Methodology and Results The authors report that, “This study focused on household tap water in proximity to floricultural plantations and in the ESPINA [Secondary Exposures to Pesticides among Children and Adolescents] participants’ homes with a range of NNI and total pesticides in urinary metabolite samples of the children.” They continue: “Participant households in the water study were […]

(Beyond Pesticides, March 20, 2026) Biopesticides represent a kind of Utopian destination in the landscape of agricultural sustainability. If only they could ensure planetary harmony. A review of botanical biopesticides in the March 11 issue of Toxics raises important questions that require scrutiny and review under the pesticide registration process and when used in organic systems under the Organic Foods Production Act. The term biopesticide can be misleading, and any replacements for synthetic pesticides cannot be taken only on faith. As Beyond Pesticides has noted previously, the U.S. Environmental Protection Agency’s (EPA) definition of biopesticides—“derived from such natural materials as animals, plants, bacteria, and certain minerals”—is broad, vague, and used differently by different interests. EPA regulates biopesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) in three categories: Substances that interfere with mating, such as insect sex pheromones, as well as various scented plant extracts that attract insect pests to traps; Microbial pesticides consisting of a microorganism (e.g., a bacterium, fungus, virus, or protozoan) as the active ingredient; and Plant-Incorporated-Protectants (PIPs), pesticidal substances that plants are genetically engineered to produce. The review by Sandra Petrovic, PhD, and Andreja Leskovac, PhD, of the University of Belgrade, highlights the need not to […]

(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 […]
