(Beyond Pesticides, June 18, 2026) Friday, June 19, is Juneteenth, a commemoration of the abolition of slavery and a celebration of human freedom. “Injustice anywhere is a threat to justice everywhere,” Reverend Doctor Martin Luther King, Jr proclaimed. This truth raises societal concerns of continuing systemic environmental racism and institutional failures of predominantly white institutions and the need to protect those at disproportionate risk, specifically Black, Indigenous, and People of Color (BIPOC) communities, from agricultural and industrial pollution. [Juneteenth is a celebration of freedom for the last 250,000 enslaved people in Galveston, Texas, but it is also a reminder that justice has not historically been “swift” or complete for Black Americans. The holiday commemorates the abolition of slavery in Texas on June 19, 1865, two and a half years after the Emancipation Proclamation. Juneteenth, officially recognized as a federal holiday since 2021, commemorates the arrival of Union soldiers in Galveston, Texas, to free enslaved people per the Emancipation Proclamation that was issued two and a half years prior. While June 19, 1865, does not mark the legal end of slavery nationwide, it was a crucial moment in the fight for freedom and continues to highlight the ongoing fight for human […]

(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 11, 2026) A study of honey bee colonies in Florida and California, published in Environmental Toxicology and Pharmacology, finds elevated mortality from pesticide residues, including those that have been documented to threaten pollinators. As the authors describe, “While bees die from multiple, often interacting, stressors, here we show single contributors at levels capable of causing acute harm.” The presence of miticides, fungicides, herbicides, and insecticides within the bee colonies, including in the bodies of dying bees, further highlights pesticides as drivers of bee declines. By sampling both dying bees and in-house bees for chemical residues, the researchers are able to compare symptomatic colonies and control colonies. The authors note, “Our findings differ from previous screenings, which cast a broad net, screening agrochemicals in colonies nationwide, and not necessarily from impacted operations.” This study, however, shows the presence of specific pesticide residues in commercially managed colonies after die-off incidences. The neonicotinoid insecticide imidacloprid, in particular, is widely detected and found in high levels, with the researchers identifying the compound as the largest contributor to bee death. Background Scientific literature linking pesticides, including neonicotinoids, to adverse impacts on pollinators continues to mount, as do the devasting population declines of […]

(Beyond Pesticides, June 10, 2026) Adding to the wide body of science connecting the weed killer paraquat to deleterious health and environmental effects, Investigate Midwest recently released an investigative news article connecting air emissions of paraquat from chemical plants in the Mississippi Basin to Parkinson’s disease, among other adverse health effects. The herbicide is also fatal to humans with a single sip, as documented in the article, entitled “This herbicide is so toxic it’s been banned in over 70 countries. But plants in the South are releasing it into the air.”  In capturing the story of Wayne County, Mississippi, where approximately 20,000 people live surrounded by forest and farmland, Investigate Midwest sheds light on the connection between the Sipcam Agro plant that processes and emits paraquat. The plant is located in the county with among the highest U.S. rates of Parkinson’s disease deaths, the top 7% of all U.S. counties.  Background on Paraquat  Paraquat has been on the market since the 1960s, created by a predecessor of Syngenta. In March of this year, Syngenta announced it would stop producing paraquat in the UK after thousands of lawsuits, primarily by farmers and farmworkers, cite Syngenta’s failure to warn of adverse health effects like Parkinson’s disease. Stopping the production of paraquat in the UK will not prevent paraquat from entering the U.S., as “other companies and other facilities—like the one in Wayne County—will fill the gap, likely increasing the amount of paraquat they handle.”  According to previous data from the U.S. Geological Survey, approximately 11 to 17 million pounds of paraquat were sprayed annually in 2017, which may […]

(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, June 8, 2026) When the Trump administration announced that it was shutting U.S. Department of Agriculture’s (USDA) Beltsville Agricultural Research Center (BARC) in Beltsville, Maryland, U.S. Representative Jamie Raskin (D-MD) released the following statement: “This is a betrayal of American farmers, and an attack on the federal workforce that will severely damage services that the American people depend on. We are disappointed but not surprised that the Trump administration is continuing its attacks on the federal workforce, this time through wasting taxpayer dollars to relocate key USDA facilities. Let us be clear: these haphazard, unlawful relocations do not save taxpayer dollars or improve agency efficiency. We’ve seen this tactic before, and we know that it only results in brain drain, crushed morale, and cuts to vital programs American farmers depend on. We will continue to stand up for the dedicated federal workers who provide critical services to our nation as they navigate these relocations, mass firings, and the administration’s continued attacks on the civil service.” In the face of this action, which is now taking place, Beyond Pesticides has released an action to tell Congress and USDA to preserve the Beltsville agricultural research facilities that support farming and […]

(Beyond Pesticides, June 5, 2026) With increasing research covered by Daily News showing pesticides linked to epigenetic effects (alter gene expression), the mechanism has far-reaching implications for protecting health and the environment. It also raises issues related to the regulatory review process, which is inadequate in assessing this mechanism. Since the discovery of DNA, a principle called the “central dogma” has dominated genetics. This dogma states that genetic processes are a one-way street: only changes to DNA in germ cells (eggs and sperm) trigger processes in RNA and then proteins to effect changes in tissues and cells throughout the body. Any suggestion that environmental exposures, for example, could alter gene expression except in the first, exposed generation, was dismissed as “Lamarckian” and unscientific. And only changes to genes themselves could be inherited. The theory of epigenetics began developing in the 1950s, and it gradually became clear that gene expression was modifiable by external factors. Cells do have numerous ways of choreographing genes, determining which ones are turned on and off at which times and in which places. In fact, this choreography is absolutely necessary for the development of an individual from pre-conception through fertilization and the progress of an embryo to […]

(Beyond Pesticides, June 4, 2026) In a study published in Perspectives in Ecology and Conservation, researchers in Brazil find that organic farming coupled with agroecological conservation practices “promote[s] biodiversity in agricultural landscapes.” The proxy for biodiversity in this study is anurans, a type of frog or toad native to the Brazilian Pampa—a section of the South American Pampas grasslands, a globally underrecognized biodiversity hotspot. According to a scientific report reviewed by Mongabay in 2024, “nearly a third of the Brazilian portion…has been lost since 1985, largely to agricultural expansion and forestry plantations.” In the U.S. context, public health and environmental advocates continue to call for the transition to organic land management as a solution that validates the ecosystem services that biodiversity-forward agricultural systems can provide under values-aligned stewardship. Methodology and Main Findings The authors in this study, researchers at the Universidade Federal do Rio Grande do Sul, surveyed 26 artificial ponds across 16 family farms with different land management systems—9 organic farms and 7 conventional farms—located in the Serra do Sudeste region of the Brazilian portion of the Pampa grasslands. All farms were sampled three times during the 2023 to 2024 breeding seasons (twice in the October to November 2023 […]

(Beyond Pesticides, June 3, 2026) A study, published in PeerJ today, by researchers from the University of Wisconsin-Madison in the U.S. and the University of Pisa in Italy, finds that the widely used fungicide fludioxonil and its breakdown products, including a ‘forever chemical’ per- and poly-fluoroalkyl substance (PFAS), threaten environmental and human health. Through a review of scientific literature (from 2021-2025) of the ecological and health effects of fludioxonil, the authors find evidence of this chemical’s mechanisms of toxicity, including oxidative stress, that are enhanced as it degrades in the environment. Oxidative stress occurs when there is a disruption of normal cell-signaling and molecular damage, leading to an imbalance of reactive oxygen species (ROS) and free radicals (unstable oxygen molecules) that the body is unable to detoxify. In particular, sunlight exposure causes fludioxonil to break down into a PFAS that is linked to adverse health implications for the environment, wildlife, and humans.  One of the authors, Warren Porter, PhD, is a board member for Beyond Pesticides and presented at the 2021 National Pesticide Forum. Dr. Porter is an emeritus Professor of Integrative Biology and an Ardath and Robert Rodale Professor of Environmental Toxicology, with previous research showing that combinations of commonly used agricultural chemicals in concentrations that mirror levels found in groundwater can significantly influence immune, endocrine, and neurological health in animals. His research also links pesticide exposure in utero to impaired learning, changes in brain function, and […]

(Beyond Pesticides, June 1, 2026) In the face of U.S. government inaction, the California state Assembly last week passed legislation to phase out existing agricultural uses and ban new uses of PFAS (perfluoroalkyl and polyfluoroalkyl substances) pesticides. The legislation, AB 1603, which accurately defines PFAS pesticides in accordance with international standards, does allow continued residential, school and park, playing field, and community PFAS pesticide use (including mosquito spraying). The bill now moves on to the state Senate. While advocates say the bill is an important step forward, they point out that the legislation is one of many examples that compromises public and environmental health, as pesticide-associated cancer, degenerative diseases, multigenerational effects, and ecosystem decline escalate. This attack on health and the environment is happening at the same time that organic agriculture and land management prohibits the use of PFAS pesticides and all the petrochemical pesticides and fertilizers with profitable and cost-effective practices. The California victory paves the way for state action as regulators at the U.S. Environmental Protection Agency (EPA) refuse to act on clear scientific findings identifying devastating health and environmental threats. In this context, the bill serves as a call for all states to push for this type of legislation […]

(Beyond Pesticides, May 29, 2026) In a new study published in Environmental Pollution, researchers detected 15 currently used pesticides (CUPs)—including 10 pesticide compounds detected but not applied within the study’s managed fields— in the pollen of beehives in an environment meant to reflect a typical honey bee foraging range. The detection of pesticides that were not directly applied within the study’s target radius demonstrates the pervasiveness of pesticide drift into soils, streams, and bodies. In this context, public health and environmental advocates continue to call for a wholesale transition to organic land management. The findings are particularly concerning given the toxicity hazards to honey bees associated with pesticide exposure in this study and bolstered by other studies, resulting in documented threats to their health—as reviewed in this Daily News below. Methodology and Background Researchers at the University of Bern and Agroscope, the Swiss government’s agricultural research arm, conducted this research with agricultural land-use data for 2023 and 2024 from the Zurich (provincial/Canton) government. The study area was defined as a 2-kilometer radius around the hive placement site, with 4 active hives over the course of a two-year period (April 10, 2023, through May 3, 2024). The land use within the […]

(Beyond Pesticides, May 28, 2026) Researchers from France and Germany, as published in Agriculture, Ecosystems & Environment, find that declines in bird populations are strongly linked to their diets, with insectivorous birds experiencing the greatest impacts. “Overall, our results emphasize the strong association between insecticide use and insectivorous bird declines,” the authors state. They continue: “We found a consistent negative association between insecticide use and population trends of insectivorous birds, the most abundant group, regardless of migration strategy. This pattern suggests indirect effects linked to the depletion of insects as a food source.” In analyzing bird population trends in France over 15 years and comparing bird responses across diets and pesticide types, this study highlights the negative association between insect population declines and insectivorous bird population declines that are linked to agricultural intensification. Study Background The impacts of pesticides on birds, as described on Beyond Pesticides’ resource page, can occur through various routes of exposure. Birds can be exposed to pesticides directly through ingestion of seeds that have been treated with pesticides, or indirectly through consumption of small insects and other animals that have ingested the pesticides themselves, leading to secondary poisonings of the birds. They can also be indirectly […]

(Beyond Pesticides, May 26, 2026) Earlier this month, with global attention focused on 12 known or suspected cases of hantavirus, including three deaths, on a cruise ship expedition in the South Atlantic, issues of rodent management, vector control, and disease transmission have made headlines around the world. The incident raises important questions about rodent biology, identification of virus location, method of disease transmission, cleaning practices, and ultimately control and prevention measures that are not harmful to people, wildlife, and ecosystems. The incident also shines a spotlight on the critical importance of the United States’ collaboration in international organizations, particularly the World Health Organization (WHO), in a world of international travel (18 on the ship live in the U.S.), where transmissible diseases extend beyond countries’ borders. With the Trump Administration defunding international programs and withdrawing from WHO, most medical experts agree that the world and U.S. residents are at heightened threat from transmissible diseases that move throughout the world. (See U.S. Abandons International Collaboration on Existential Health Challenges at Time When Most Needed.) In this context, Beyond Pesticides has launched a local campaign to Tell local officials to use good sanitation and management to prevent rodent problems and not use hazardous […]

(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 21, 2026) An important study by cancer researchers in Barcelona, Spain at once shows a path forward in illuminating the long-term, multi-generational, health damage from pesticide exposures and demonstrates how extraordinarily dilatory U.S. agricultural regulators are in protecting public health. The study, “Epigenetic fingerprints link early-onset colon and rectal cancer to pesticide exposure,” found a robust association between methylation markers (for gene expression associated with cancer) and exposure to a number of pesticides, with the herbicide picloram having the strongest link. Other pesticides with strong associations include the weedkillers atrazine, glyphosate, nicosulfuron, and insecticide esfenvalerate. Colon cancer is expected to double, and rectal cancer to quadruple, in this young age group by 2030. This sharp contrast between age groups suggests that environmental exposures, rather than strictly genetics, are involved. The authors are concerned with the alarming rise in early onset colorectal cancer (EOCRC) not only in the highly developed world but also in less-industrialized countries. This increase appears to be connected with age cohorts and the differences in lifestyle and environmental exposures between older and younger cohorts. According to a commentary on the study by researchers from the Dana-Farber Cancer Institute, in the U.S., the incidence of colorectal […]

(Beyond Pesticides, May 20, 2026) A study of two pollinator species, honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata), finds oxidative stress (OX)— an imbalance between antioxidant defenses and excess reactive oxygen molecules (species), or ROS—resulting from exposure to non-living (abiotic) stressors, such as synthetic chemicals, leading to cell damage. Regulatory bodies, including the U.S. Environmental Protection Agency (EPA), do not routinely evaluate oxidative stress as a standalone or required endpoint in standard pesticide registration protocols. In comparing pollinator responses to different pesticides and pest control management practices, the lowest levels of OX are exhibited in organically managed systems, as described in the research published in Physiological Entomology. Quantifying the oxidative stress levels in bees and their larval stages from three landscapes (conventional, organic, and roadside) shows that minimum exposure to agrochemicals and high traffic-related pollutants results in the lowest levels of OX. “Overall, these findings show that variation in pesticide residue profiles across landscapes is associated with different OX responses in bees,” the authors state. “Given the essential ecosystem services provided by bees, our findings underscore the urgent need for landscape-level strategies to reduce pollinator exposure to chemical stressors.” Background Oxidative stress occurs when there is a […]

(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 15, 2026) As water bodies continue to be contaminated by pesticides and fertilizers used in chemical-intensive agriculture, international researchers find increasing threats to both aquatic and terrestrial food webs with insect transmission of pesticide residues from water to land. Published in Environmental Pollution, the study authors analyze insect species with complex life cycles “with an aquatic phase as larvae and a terrestrial phase as winged adults when they serve as prey for many aerial insectivores, such as bats and birds.” As the researchers explain, these insects act as vectors, transferring pesticides from water bodies into terrestrial food webs. As a result of studying feces from birds and bats that prey on these insects, the authors find residues of 16 current-use pesticides, two legacy compounds, and six metabolites (breakdown products). The study results illustrate that pesticide contamination occurs through the ingestion of contaminated prey from aquatic systems, as all of the substances recovered in the fecal samples are detected in the water bodies within the study region. The transfer of pesticides from emerging insects to other species in the food web further threatens biodiversity and ecosystem functioning. In summary, the authors state, “Our study is among the first […]

(Beyond Pesticides, May 14, 2026) In a new report by Friends of the Earth, federal organic standards as defined by the Organic Foods Production Act (OFPA) are identified as a bedrock “Threshold Program” with high minimum standards that combine three core features—synthetic pesticide and fertilizer prohibitions, soil health requirements, and third-party verification and enforcement systems. In other words, the review of thirteen regenerative and regenerative organic labels and enforcement systems must be built on enforceable standards. This criterion is foundational to the growth of the U.S. organic sector to over $76.6 billion in domestic sales in 2025, expanding at a pace nearly twice the rate of growth (6.8 percent) compared to the national agricultural sector more broadly (3.4 percent). Main Findings The report focuses on the principles of 13 different regenerative labeling and certification systems on the market, including a comparison of federal organic standards and the U.S. National Organic Standards Board (NOSB). The main findings and features of the report include: “Truly regenerative agriculture must phase out dependency on agrochemicals that undermine the very ecological functions on which resilience depends.” The various “regenerative” agriculture labels currently on the market are significantly varied in terms of pesticide and fertilizer restrictions […]

(Beyond Pesticides, May 13, 2026) Published in Toxics, a review finds that per- and polyfluoroalkyl substances (PFAS) can heighten the risks to exposed organisms from environmental contaminants. Mixtures of these compounds can negatively impact the nervous, cardiovascular, immune, and reproductive systems, particularly in aquatic organisms, and threaten overall biodiversity. The review highlights synergistic effects (greater in combination) observed in mixtures, such as PFAS with pesticides and microplastics, that can cause enhanced oxidative stress, neurotoxicity, developmental defects, and reproductive dysfunction, among others. “The objectives were to evaluate the toxicological effects of mixtures of the selected contaminants with PFAS on aquatic organisms to better understand biological responses in animals,” the study authors explain. “Based on our review, data suggest that PFAS can modify the toxicity of co-occurring pollutants.” Background PFAS were first created in the 1930s and have since been used in many industries and in the production of many products. The multitude of PFAS sources and exposure routes leads to widespread contamination of the environment and organisms. PFAS in agriculture represents a large source, as PFAS can be pesticide active ingredients, used in the plastic containers that pesticides are stored in, and as surfactants in pesticide products. Additionally, PFAS are used in many other […]

(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 […]
