(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 […]

(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 6, 2026) While mosquito season is not yet here, Beyond Pesticides has launched an action to remind people and policy makers that mosquito management requires the enhancing of natural ecosystems, including bird populations, in communities and residential areas to reduce the population of these biting insects. The campaign draws on the science showing that an unbalanced ecosystem eliminates some of the most attractive and helpful allies in mosquito management—birds. Incorporating the awareness of healthy ecosystems in communities and yards into local and state policies and practices is a critical pest management tool. The action calls on Governors and Mayors to ensure ecological management of mosquitoes by eliminating the use of pesticides that threaten mosquito predators. An article, “The Ecological Impact of Pesticides on Non-Target Organisms in Agricultural Ecosystems” (2024), captures the importance of land management and habitat to protect a a balance of organisms, including bird populations. The authors, in the context of agroecosystems but generally applicable, write: “Pesticide exposure reduces ecosystem resilience, changes community dynamics, and accelerates population reductions in a variety of organisms, including predatory arthropods, bees, and butterflies. Furthermore, bird populations—which are essential to agroecosystems—face a variety of difficulties as a result of habitat degradation, food […]

(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 26, 2026) A review of pesticide exposure from a family member working in agriculture (“take-home” residues) finds that pesticide levels in the home are elevated between 2.6- and 3.7-times. This and other nonoccupational exposure data from homes are drawn from the Agricultural Health Study (AHS), a National Cancer Institute (NCI) and National Institute of Environmental Health Sciences (NIEHS) prospective study of cancer and other health outcomes in a cohort of licensed pesticide applicators and their spouses from Iowa and North Carolina. Between 1993 and 1997, with follow-up between 1999 and 2021, AHS tracks occupational and nonoccupational exposure and subsequent health effects from pesticide exposure. The current study, published in Environmental Advances, reexamines a quantitative analysis on nontarget, “active-ingredient-specific” exposure to pesticides from multiple pathways—applying new criteria to AHS spousal exposure to the insecticide chlorpyrifos and the herbicide atrazine. The three pesticide exposure pathways include take-home, agricultural drift, and residential use. Building on a 2019 study, researchers consider data from additional studies published between 2019 and 2024, “providing support that all three pathways contribute to pesticide exposure.” More importantly, the updated estimates of nontarget exposure to chlorpyrifos and atrazine are overall strengthened by the incorporation of new data, highlighting the […]

(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 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 […]

(Beyond Pesticides, February 4, 2026) Using data from the Agricultural Health Study (AHS) database launched in 1993 by the National Cancer Institute and the National Institute of Environmental Health Sciences, research study results “show greater diabetes risk“ from exposure to organochlorine, organophosphate, and carbamate insecticides, phenoxy and other herbicides, and the fumigant carbon tetrachloride/disulfide exposure. The study, published in Environment International, evaluated nearly 4,000 diabetes cases drawn from AHS follow-up surveys between 1999 and 2021. Results Researchers found evidence of an association between 18 pesticide active ingredients and diabetes. These included two phenoxy herbicides, 2,4,5-T and 2,4,5-TP, and seven organochlorine insecticides (DDT, aldrin, dieldrin, chlordane, heptachlor, toxaphene, and lindane). While all these organochlorine pesticides are banned for use in the U.S. (with the exception of pharmaceutical uses of lindane), legacy residues of the chemicals and/or their metabolites continue show up in the environment, food, and the human body, and 2,4,5-T and its TCDD dioxin contaminant has multigenerational effects. There was exposure risks among other pesticides were identified as well, including: 3 organophosphate insecticides (diazinon, malathion, and phorate); 2 carbamate insecticides (carbofuran and carbaryl); 3 other herbicides (butylate, metribuzin, and chlorimuron ethyl); and the fumigant carbon tetrachloride/disulfide. The median age of […]

(Beyond Pesticides, January 27, 2026) A three-part study published in Molecular Neurodegeneration draws a connection between Parkinson’s disease (PD) and the organophosphate chlorpyrifos. “Since chlorpyrifos (CPF) exposure has been implicated as a risk factor for PD, we investigated its association to incident PD and if this association is biologically plausible using human, rodent, and zebrafish (ZF) studies,” the researchers state. Together, the three experiments “strongly implicate exposure to CPF as a risk factor for developing PD,” as the authors find that exposure, even at very low concentrations, causes selective toxicity to dopaminergic neurons that are critical for functions of movement, cognition, emotion, and more. The results reveal that in humans, long-term residential exposure is associated with more than a 2.5-fold increased risk of developing PD, while exposure in mice causes “motor impairment, dopaminergic neuron loss, microglial activation, and an increase in pathological α-synuclein (α-syn) [proteins primarily found in the brain].” The researchers continue, “Using ZF, we found that CPF-induced dopaminergic neuron loss was at least partially due to autophagy dysfunction and synuclein accumulation, as knocking down LC3 [a protein chain] recapitulated the dopaminergic neuron loss.” These three studies highlight the association of CPF with increased risks for developing PD, as […]

(Beyond Pesticides, November 14, 2025) A literature review in Ecotoxicology and Environmental Safety finds a sex-specific relationship between pesticide exposure and thyroid cancer, with heightened risks for women. “Thyroid cancer (TC) is one of the most common endocrine malignancies worldwide, yet the association between pesticide exposure and TC has not been systematically summarized,” the authors state. “This study aimed to elucidate the relationship between pesticide exposure and TC, focusing on insecticides, herbicides, and fungicides.” In the U.S., approximately 44,020 new cases and 2,290 deaths are estimated for 2025, according to the American Cancer Society, with thyroid cancer as the ninth most common cancer in women. (See research here.) TC ranks globally as the tenth most common cancer, representing a worldwide threat to both men and women. (See here.) The current study considers scientific literature on thyroid cancer and pesticide exposure by pesticide type to extract data and statistically analyze the link between exposure and risk of TC. The results indicate a positive association between exposure to insecticides, herbicides, and fungicides and thyroid cancer, with the sex-based analysis revealing the risk of TC is higher in females. Study Background and Importance As the researchers write, thyroid cancer “is one of the […]

(Beyond Pesticides, November 7, 2025) There is little dispute that modern industrial culture has produced a constellation of related chronic conditions contributing powerfully to human disease. In recent decades, attention has begun to focus on the developmental origins of health and disease—prenatal exposures to pesticides, for example, that contribute to diseases in adulthood, such as cardiovascular and metabolic problems, along with the combination, known as cardiometabolic syndrome. Cardiometabolic disorders include obesity, hypertension, cholesterol imbalances, and insulin resistance. The usual suspects blamed for the syndrome are poor diet, physical inactivity, and genetic predisposition. These are all well-established risk factors, but they fail to fully account for the sharp rise in cardiometabolic syndrome globally. Obesity prevalence has doubled and diabetes quadrupled over the last 40 years, according to the Non-Communicable Diseases (NCD) Risk Factor Collaboration. In a study on early life exposure to a pesticide mixture, researchers analyze sex differences in cardiometabolic outcomes from prenatal and early life. The study was conducted by an international team of scientists led by Ana M. Mora, M.D., of the Center for Environmental Research and Community Health at the University of California, Berkeley, using data from the Center for the Health Assessment of Mothers and Children of […]

(Beyond Pesticides, October 31, 2025) A review in Lancet Neurology provides a clear snapshot of the state of scientific understanding of Parkinson’s disease and how medicine and policy could be improved by shifting focus to the primary causes of the disease, namely environmental toxicants, and to emphasize prevention rather than devoting resources only to treatments and a cure. The study, led by Ray Dorsey, M.D. of the Atria Research and Global Health Institute and the University of Rochester Medical Center, focuses on three classes of environmental toxicants: pesticides, dry cleaning and degreasing chemicals, and air pollution. Because these are pollutants introduced by humans, the authors say, they should be controllable, and “Parkinson’s disease could be thus largely preventable.” According to the review, in the last five years, new evidence has accumulated about three types of pesticides of particular concern. They are not all insecticides, which is the pesticide category most associated with neurological damage. Paraquat is a herbicide used on corn, soybeans, and cotton. Rotenone is used to kill rats and insects. Organochlorine insecticides comprise the third class. The review notes that there are many other pesticides that are neurotoxic and may have common mechanisms of action leading to Parkinson’s and […]

(Beyond Pesticides, October 24, 2025) A literature review published in Science of the Total Environment reports numerous peer-reviewed studies associating prenatal and childhood pesticide exposure to measurable alterations to children’s immune systems, including indicators of immunosuppression and increases in pro-inflammatory cytokines, among other adverse health effects. These immune system alterations are linked to higher infection risk and potentially contribute to autoimmune diseases and allergies later in life. For over four decades, Beyond Pesticides has tracked the peer-reviewed science and identified a preponderance of evidence linking pesticide and chemical-dependent pest management to adverse human and ecological health effects. In this spirit, public health and environmental advocates continue to call for a wholesale transition to organic land management and organic pest management as biodiversity, public health, and climate crises continue to mount. This mission supports the growth of the Parks for a Sustainable Future Program, where nineteen cities in eleven states across the country engage in pilot projects to transition parks, playing fields, and schoolyards to organic management practices and protect the health of children. Background and Methodology “This study aimed to evaluate the extent of immunotoxicity and correlation between exposure to pesticides and immune system alterations in children under five years […]

(Beyond Pesticides, October 23, 2025) A global literature review of pesticide residues in marine seaweed, published in Marine Pollution Bulletin, highlights the widespread presence of pesticides in bioindicator species. As vital coastal primary producers, seaweed acts as a key indicator for regional pesticide contamination patterns. The bioaccumulation within seaweed species also threatens consumers, including humans, as the chemicals can biomagnify as they move through the food web. Pesticide contamination in waterways allows residues to bioaccumulate in seaweed species, presenting risks to public health, biodiversity, and ecosystem functioning. In addition to the support seaweeds provide for ecosystems, they provide food sources for a multitude of organisms and are of growing socioeconomic importance. “This systematic review identifies, critically evaluates, and synthesizes recent global literature (2015–2024) on pesticide residues detected in seaweeds to delineate contamination patterns,” the authors share. The findings highlight the harmful impacts of petrochemical pesticides on multiple species. Many aquatic species rely on seaweed as a food source, including fish, sea urchins, crabs, snails, brittle stars, and marine mammals such as manatees and sea turtles. Even bacteria and filter feeders consume seaweed when it is decomposed. Birds and land mammals also consume seaweed, including humans who utilize seaweed in various […]

(Beyond Pesticides, September 17, 2025) A study in Environmental Science & Technology finds additive effects of a synthetic pyrethroid insecticide (cypermethrin) and two fungicides (azoxystrobin and prochloraz) on biological control, biomass of major invertebrate trophic groups (position in food web), and soil ecosystem processes in arable systems (land suitable for growing crops). The study authors further highlight the failure of pesticide regulations to consider elaborate trophic interactions and pesticide mixtures, as well as additive and synergistic effects within their assessments, calling attention to the complexity of real-world exposures and the lack of research to fully understand the implications of chemical use for agricultural and land management purposes. “Arable systems have a high dependence on diverse natural biota to support pest control, soil bioturbation, and nutrient recycling,” the researchers write. These communities rely on a balance of organisms within various trophic levels in order to function and provide vital ecosystem services. Disruptions caused by environmental contaminants, such as pesticides to nontarget organisms, impact entire ecosystems and overall biodiversity. As the authors state, current risk assessments underestimate the real-world risks of petrochemical pesticides and synthetic fertilizers that, despite a wide body of science connecting exposure to deleterious health and environmental effects, are […]

(Beyond Pesticides, August 21, 2025) The presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome, according to a study of the synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The study in Pesticide Biochemistry and Physiology adds to the growing body of science on the severely declining bee population by investigating the toxic effects of both the parasites and pesticide stressors in honey bees (Apis mellifera). “Given that V. destructor may increase bees’ sensitivity to imidacloprid by compromising their physiological health and immunity, this study systematically assesses the effects of V. destructor infestation and imidacloprid exposure on honey bee survival, detoxification enzyme activity, and gut microbiota,” the authors explain. The intestinal tract and gut microbiome are crucial for digestion, metabolism, nutrient absorption, immune regulation, and pathogen defense. Within honey bees, the gut microbiome is “highly susceptible to external environmental stressors, such as pesticide exposure and parasitic infections [and] these disturbances can lead to microbial imbalances, ultimately affecting bee health.” (See studies here and here.) Previous research earlier this year, captured in Daily News Variability […]

(Beyond Pesticides, August 14, 2025) A review in Clinical and Experimental Obstetrics & Gynecology links various classes of environmental pollutants including pesticides and per- and polyfluoroalkyl substances (PFAS), both of which Beyond Pesticides has extensively covered, to adverse effects on the female reproductive system and common mechanisms of toxicity. These chemicals “disrupt the hypothalamic-pituitary-gonadal axis (HPG), impair ovarian function, and contribute to reproductive dysfunction through mechanisms such as oxidative stress, hormonal disruption, and epigenetic [gene expression or behavior] modifications,” the authors say. This leads to menstrual irregularities, infertility, and pregnancy complications, as well as increases in the risk of reproductive system disorders such as endometriosis, polycystic ovary syndrome (PCOS), and ovarian cancer, among others. “Additionally, transgenerational effects mediated by epigenetic modifications, germ cell damage, and placental transfer may adversely affect offspring health, increasing the risk of reproductive dysfunction, neurodevelopmental disorders, metabolic diseases, and cancer,” the researchers explain. This study, integrating recent epidemiological and experimental findings, provides an overview of major chemical classes that threaten women’s health and highlights the need for immediate action. As the authors point out, female reproductive health is important not only for those who choose to plan for a family but also for the overall well-being […]

(Beyond Pesticides, August 7, 2025) The novel study published in Arthritis & Rheumatology is the largest investigation of rheumatoid arthritis (RA) in women to date, finding evidence of heightened risks when exposed to insecticides through data collected from over 400 eligible women in the Agricultural Health Study (AHS). AHS participants include a cohort of thousands of licensed pesticide applicators and their spouses from Iowa and North Carolina, with this particular study as the first to consider the link between pesticide exposure and RA as it affects women’s health.   “Growing evidence suggests farming and agricultural pesticide use may be associated with rheumatoid arthritis (RA), but few studies have examined specific pesticides and RA among farm women, who may personally use pesticides or be indirectly exposed,” the study authors explain. The findings reveal that organochlorine insecticides that continue to persist in the environment, as well as organophosphate and synthetic pyrethroid pesticides used in public health or residential settings, correlate with RA diagnoses in women.  As shared in previous Daily News, for the most part organochlorine pesticides, including dichlorodiphenyltrichloroethane (DDT), are no longer used worldwide, but the legacy of their poisoning and contamination persists. These compounds are primarily made up of chlorine atoms, […]

(Beyond Pesticides, August 6, 2025) A study published in Science of The Total Environment finds that “chronic pesticide exposure alters metabolism and impairs fish growth and health.” With increasing concern about the long-term consequences of pesticide persistence in ecosystems, the scientific literature continues to expand the body of research findings on adverse effects, including impacts on marine or aquatic ecosystems and organisms. Given the known and growing risks, there is an ongoing movement to move beyond petrochemical-based chemicals for agriculture and land management by adopting policies and programs that advance organic criteria and principles, as outlined in national organic law and practiced by tens of thousands of certified farmers and land managers across the country, and even more at the international level. Background and Methodology “The objective of this study was to assess the physiological responses of juvenile P. lineatus exposed to environmentally relevant pesticide mixtures by integrating multiple biological endpoints across sub-individual and organismal levels,” the authors write. The study was conducted at two sites in the Tibagi River watershed located in Paraná, a southern region in Brazil. There was a reference site (RFS) and an agricultural site (AGS), the former having minimal pesticide contamination and the latter having […]

(Beyond Pesticides, July 30, 2025) The definition of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” due to their persistence, continues to be debated in regulatory agencies, with many scientists arguing that certain types of chemicals in this vast group are not accurately captured in risk assessments. A wide body of science on the adverse health and environmental effects of PFAS exists, as these synthetic chemicals have become ubiquitous in nature, wildlife, and humans, as demonstrated by biomonitoring studies. Recent research, documented in a literature review in Environmental Science & Technology and additional articles, highlights the importance of a universal, cohesive definition of PFAS that incorporates all fluorinated compounds, including the long carbon chain PFOA (perfluorooactanoic acid) and PFOS (perfluorooctanesulfonic acid) as well as the ultrashort-chain perfluoroalkyl acids (PFAAs). In order to protect health and the environment from the ever-increasing threat of both long and short chain PFAS’ adverse effects, including cancer, endocrine-disrupting effects, and immune system damage, a comprehensive definition of the compounds causing harm is critical to adequate protection and regulatory decisions. The multitude of sources of PFAS and various exposure routes leads to widespread contamination of the environment and organisms. PFAS in agriculture represents a […]

(Beyond Pesticides, July 29, 2025) Are neurological diseases increasing around the world? Yes and no, according to a report published by The Lancet in 2024 on the global burden of nervous system diseases between 1990 and 2021. About 3 billion—a third of the world’s people—suffer from some nervous system condition. These diseases cause 11 million deaths and 443 million disability-adjusted life years (DALYs), which are a measure of the years lost to illness, disability, or early death. Neurological disorders are now the world’s largest source of disability. The Lancet report does not include an analysis of the role of pesticides in the burden of neurological disease worldwide, although environmental health research continues to expand the evidence that pesticide exposure is a major contributor to that burden. The Lancet report indicates that DALYs from Parkinson’s disease have increased by 10 percent, and autism spectrum disorder and dementia by 2 percent each. Multiple sclerosis has declined by 11 percent, according to the report. Importantly, most of the improvement has come from medical interventions, not prevention—in other words, people are living longer with the diseases rather than avoiding them altogether. But this is not true globally: The burden of disease, and particularly premature death, […]
