The Fallacy of Glyphosate Exemptions Demonstrates the Importance of Sound Science on Hazards and Solutions

(Beyond Pesticides, January 30, 2024) The City Council of Brighton and Hove (England) is preparing to expand the use of glyphosate after widespread public complaints over the growth of Japanese knotweed and a program of manual clearance. This imminent local land management decision flies in the face of substantial research on the health and ecological impacts of glyphosate-based herbicides, including from Aaron Blair, PhD—former chair of the International Agency for Research on Cancer (IARC) working group on glyphosate and former branch chief (now scientist emeritus) of the Occupational Studies Section, National Cancer Institute (NCI). Advocates are concerned that the city council is basing this rationale on the fact that the European Commission reapproved use of glyphosate in 2023 for a ten-year period and not the body of scientific literature on health and ecosystem effects as well as alternative practices and products. According to a recent ENDS Report, “The [City of Brighton and Hove] council banned the use of glyphosate in 2019 – with an exception for killing invasive species [‘in exceptional cases’] such as Japanese Knotweed – after it was linked to health concerns and a decline in bee populations. As part of this it was agreed that the removal […]

Study Finds Pyrethroid Insecticide Levels in Newborns that Increase in First Year of Life

(Beyond Pesticides, January 26, 2024) In addition to maternal (mothers) exposure, children experience exposure to pyrethroid insecticides earlier in life as levels significantly increase post-natal (after birth), according to a study published in Frontiers in Public Health. This study is one of the few studies to investigate pyrethroid exposure concentrations in the urine of newborns and children within their first year of life. However, this research reiterates what many other studies demonstrate on pyrethroids’ impacts on children’s health, primarily due to their notorious neurotoxic properties. The findings indicate that exposure to pyrethroids during pregnancy and early childhood exposure has links to adverse health effects, including neurodevelopmental delays (e.g., autism), behavioral issues (e.g., attention deficit [hyperactivity] disorder), and endocrine disruption (e.g., delay in puberty). Pesticide exposure during pregnancy is of specific concern as health effects for all life stages can be long-lasting. Just as nutrients are transferable between mother and fetus, so are chemical contaminants. Studies find pesticide compounds in the mother’s blood can transfer to the fetus via the umbilical cord. Therefore, pesticide exposure during pregnancy affects both the mother and child’s health. Beyond Pesticides has covered a variety of pregnancy risks from pesticides and other toxic chemicals, including these in just […]

Bill to Protect Birds and Bees in New York Raises Political Challenges to Addressing Ecosystem Collapse

(Beyond Pesticides, January 25, 2024) Legislative efforts to curtail some life-threatening pesticides associated with birds and bees (and other pollinators) decline were weakened in New York State at the end of December 2023 as the governor negotiated and stripped elements of a bill relating to agriculture that had passed the legislature—again illustrating the grip of the agrichemical industry on public policy intended to begin to address the crisis in ecosystem collapse. (See “Study Cites Insect Extinction and Ecological Collapse.”) In passing the Birds and Bees Protection Act, New York joined New Jersey, Nevada, and Maine in banning most nonagricultural uses of neonicotinoid (neonic) insecticides, but, in last-minute changes to avoid the governor’s veto, failed to phase out corn, soybean, and wheat seeds coated with these chemicals. [Pointing to an exemption in federal law that has been challenged by advocates, the U.S. Environmental Protection Agency (EPA) does not regulate treated or coated seeds as pesticides despite their toxic pesticidal properties.] In New York State, the governor can, in consultation with the leadership of the legislative branch, negotiate language changes (called Chapter Amendments) in legislature-passed legislation (originally enacted) before deciding to sign it into law or can simply choose to veto the legislation.

Oxidative Stress Measured with Biomarkers Links Pesticide Exposure to Cancer

(Beyond Pesticides, January 24, 2024) A study published in Environmental Sciences Europe finds that 2,4-D, pyrethroid (PRY), and organophosphate (OP) pesticides increase the risk of cancer through oxidative stress (OS). The study highlights that pesticides that increase cancer risk also raise inflammation biomarkers that indicate damage to organs (e.g., liver) via oxidative stress. Additionally, different cancers show different sensitivities to pesticides; thus, cancer risk changes with exposure concentration and pattern. Despite a plethora of studies linking cancer and pesticide exposure, very few cover the mechanisms involved in cancer development, including OS. Only five to ten percent of cancers are hereditary. However, environmental or lifestyle factors, like chemical exposure, can make an individual more susceptible to cancer development through gene mutation. In fact, a vast amalgamation of research links cancer risk to pesticide exposure, which augments the risk of developing both common and rare cancers. Therefore, studies like this highlight the importance of understanding how pesticide use can increase the risk of latent diseases, which do not readily develop upon initial exposure. Using data from the National Health and Nutrition Examination Survey (NHANES), researchers investigated the link between the risk of several cancers and pesticide exposure. The researchers also thoroughly evaluated […]

Study Shines Light on Common Herbicides 2,4-D and Glyphosate Impacts on Behavioral Function

(Beyond Pesticides, January 19, 2024) A study published in Environmental Health Perspective is one of the first to indicate a link between exposure to the herbicides 2,4-D and glyphosate and the impairment of behavioral performance (i.e., attention/inhibitory control, memory/learning, language, visuospatial processing, and social perception). These adverse effects associated with the neurotoxic impacts of pesticides on behavior have been previously documented. For example, a study in August 2023 finds oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, increased the likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Although previous studies find neurotoxic effects from exposure to these herbicides, very few until now have evaluated how this neurotoxic exposure impacts neurotypical behavior among youth (children and teenagers). The ubiquitous use of glyphosate and 2,4-D use in agriculture—which leaves residues of the toxic chemicals in food and in public areas (e.g., parks and walkways) creates a creates a significant risk for exposure. Glyphosate is already implicated in or proven to lead to the development of numerous health anomalies, including cancer, while 2,4-D also has a range of potential hazards, including cancer. Therefore, studies like this help local and government officials make holistic decisions regarding the use […]

Take Action: EPA Challenged for Not Assessing Claimed Pesticide “Benefits,” Opens Public Comment Period

(Beyond Pesticides, January 16, 2024) The U.S. Environmental Protection Agency (EPA) has long been criticized for its failure to evaluate the effectiveness (or efficacy) of all the pesticides it registers. A petition, for which there is now an open public comment period (submit comments by January 22, 2024), challenges what advocates call a basic failure of the agency to evaluate the claimed benefits of pesticides. Because of this long-standing situation, those who purchase pesticides do not know that the pesticides they buy will meet expectations for control. For farmers, that means that EPA has not evaluated whether the pesticide’s use actually increases productivity of the treated crops and/or whether over time the target pest (weed, insect, fungus) will become resistant. For consumers, it also means that there is not an independent analysis of whether the pesticide products work. As EPA implements the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), not only is there no agency assessment of whether the pesticide’s use will achieve its intended purpose, there is not a determination as to whether there is a less toxic way of achieving the pest management goal. As Beyond Pesticides cited last year, a piece published in the Proceedings of the […]

Pesticides’ Role in Lower Sperm Counts and Reproductive Harm in Men Again in Science Literature

(Beyond Pesticides, January 10, 2024) Exposure to endocrine-disrupting chemicals (EDCs) negatively impacts testicular function and may cause sperm count declines over time, according to a 2022 review published in Endocrine. The findings indicate that this occurs regardless of whether exposure is prenatal (before birth) or postnatal (after birth). More recent work from October 2023 confirms the connection between male reproductive health and exposure to organophosphate and carbamate insecticides and the weed killer glyphosate—as many pesticide products containing these chemicals are classifiable as endocrine disruptors (ED). Just last year, a meta-analysis from researchers at Mount Sinai Medical Center, the Hebrew University of Jerusalem, and the University of Copenhagen, among others, finds that the drop in global sperm count is accelerating, dropping by 51.6 percent from 1973 through 2018. The U.S. regulatory system, under the authority of the U.S. Environmental Protection Agency (EPA), has not kept pace with the science and does not fully evaluate pesticides in wide use for endocrine disruption, despite a requirement in 1996 law (the Food Quality Protection Act) to begin that testing and evaluation nearly three decades ago. In 2021, Beyond Pesticides reported that the Office of the Inspector General (OIG) for EPA issued a damning report on the […]

Work-Related Pesticide Exposure Puts Farmers at Risk of Cognitive (Intellectual) Harm

(Beyond Pesticides, January 4, 2024) A review published in the Journal of Neurosciences in Rural Practice finds an association between farmers’ pesticide exposure and cognitive impairment. Specifically, farmers suffer from attention deficit, lack of information processing, non-comprehension of verbal cues, slow processing speed, memory loss, sluggishness, speech difficulties, and impaired motor function. Additionally, the risk of adverse effects from exposure increases with time spent around pesticides, like in other occupational (work-related) settings. Although pesticide exposure may not be the only factor involved in cognitive impairment, exposure can work synergistically (together) with other factors, triggering neurotoxicity. Pesticides play various roles in causing or exacerbating adverse health outcomes like neurotoxic effects and chemical damage to the brain. Numerous pesticides impair neurological function, especially for chronically exposed individuals (e.g., farmworkers) or during critical windows of vulnerability and development (e.g., childhood, pregnancy). Mounting evidence over the past years shows that chronic exposure to sublethal (low) levels of pesticides adversely affects the central nervous system (CNS) and neural receptors, such as connections between nerves, the brain, enzymes, and DNA. Specifically, researchers identify agricultural chemical exposure as a cause of many adverse CNS impacts and neurological diseases, including Alzheimer’s, amyotrophic lateral sclerosis (ALS), and Parkinson’s disease. The researchers reviewed scientific articles published in […]

Loss of Chromosome Y in Male Farmers Genotoxic Implications for Cancer

(Beyond Pesticides, January 3, 2024) A study published in Environmental Health Perspectives finds elevated, chronic exposure to glyphosate throughout one’s lifetime increases the risk of mosaic loss of chromosome Y (loss of chromosome Y occurs to many men in some cells due to aging [mLOY]) that impacts a noticeable fraction of cells. Although the loss of this sex chromosome does not cause cell death, like the loss of autosomal chromosomes, the risk of mLOY is a biomarker for genotoxicity (the damage of genetic information within a cell causing mutations from chemical exposure, which may lead to cancer) and expansion of cellular response to glyphosate, resulting in the precursor for hematological (blood) cancers. This study is one of the first to identify sex-specific chromosome degradation, with stark evidence demonstrating links to various cancers, including non-Hodgkin lymphoma. The International Agency for Research on Cancer (IARC) has classified the glyphosate as a probable carcinogen or cancer-causing chemical. However, the U.S. Environmental Protection Agency’s (EPA) allowance of widespread use of glyphosate allows for adverse impacts, especially among vulnerable individuals, like pregnant women, infants, children, and the elderly. Glyphosate exposure levels and resulting residues in urine has been documented with recent data showing that four out of five (81.6%) […]

Commentary: New Year Calls for Transformational Change Starting with Chemical Use Rejection

(Beyond Pesticides, January 2, 2024) [photo credit: Alessandro Marongui, Bhopal Medical Appeal, Bhopal, 2009] The new year begins with numerous critical decisions before the U.S. Environmental Protection Agency (EPA) and its Office of Pesticide Programs, along with other federal agencies and the U.S. Congress, that determine whether the agency will continue to erode its leadership position in meeting the existential crises that threaten health, biodiversity, and climate. Given these crises, EPA under its current authority could take the action necessary to advance a transition away from the use of petrochemical pesticides, since under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) the hazards associated with pesticides are “unreasonable”—given the availability and viability of organic systems that do not utilize toxic pesticides. As EPA fails to meet the catastrophic environmental and health challenges of the day, communities and states across the U.S. are increasingly exercising their authority to restrict pesticides more stringently than the federal government. FIFRA, as affirmed by the U.S. Supreme Court in Wisconsin Public Intervenor v. Mortier (1991), does not prohibit or preempt local municipalities from adopting more stringent pesticide restrictions throughout their jurisdictions than the federal government. The U.S. Congress over the next several weeks will continue […]

Low-Dose Chronic Glyphosate Exposure Increases Diet-Induced Non-Alcoholic Fatty Liver Disease

(Beyond Pesticides, December 21, 2023) A new study published in Environmental Toxicology and Pharmacology adds to prior research indicating glyphosate promotes the occurrence of nonalcoholic fatty liver disease (NAFLD) through diet by causing liver inflammation and oxidative stress. More importantly, the predisposition for NAFLD occurred at levels within toxicological limits, which are doses of glyphosate classified as causing no adverse effects or No Observed Adverse Effect Level (NOAEL). NAFLD is a condition that causes swelling of the liver and can eventually lead to cirrhosis, cancer, or liver failure. This study highlights the Westernized diet (WD), comprised of foods enriched in saturated fats, cholesterol, and simple carbohydrates (e.g., fructose, glucose, and sucrose), plays a role in the nearly 40 percent increased risk of NAFLD. Although glyphosate disrupts gut microbes and induces liver inflammation, oxidative stress, and fatty acid levels that promote NAFLD, the combination of WD and glyphosate reduces the threshold risk for NAFLD development. NAFLD is a growing worldwide epidemic, becoming the most prevalent form of liver disease and impacting at least 25 percent of the globe. Therefore, studies like this shed light on how diet and chemical exposure can work synergistically (together) to exacerbate disease risk. The study evaluates whether choric […]

Court Finds EPA Allowance of Antibiotic Streptomycin Use on Citrus Illegal

(Beyond Pesticides, December 20, 2023) A federal district court decision last week (December 13) found illegal the U.S. Environmental Protection Agency’s (EPA) decision to register the antibiotic streptomycin for use in Florida citrus to control Huanglongbing (HLB), also known as “citrus greening,” a plant disease spread by the Asian citrus psyllid. This decision comes just as EPA may allow yet another controversial pesticide, aldicarb, whose registration faces similar issues of agency malfeasance. The streptomycin lawsuit, filed in 2021 by a coalition of farmworker and public interest groups including Beyond Pesticides, raises critical issues of antibiotic resistance, public health protection, and impacts on bees. The case was filed by: Natural Resources Defense Council and U.S. PIRG, represented by NRDC; Beyond Pesticides, Environmental Confederation of Southwest Florida (ECOSWF), Farmworker Association of Florida, Farmworker Justice, and Migrant Clinicians Network, represented by Earthjustice; and the Center for Biological Diversity, represented by in-house counsel. The Ninth Circuit Court of Appeals took EPA to task for its failure to conduct required analyses and issue findings to support the use of streptomycin for citrus greening. The court is particularly concerned about the agency’s failure to reach findings on the impacts on bees and the agency’s responsibility for […]

Groups Petition EPA to Remove from the Market the Weed Killer Glyphosate

(Beyond Pesticides, December 19, 2023) Last week, farmworker organizations and Beyond Pesticides, represented by the Center for Food Safety, filed a petition with the U.S. Environmental Protection Agency (EPA) urging that the weed killer glyphosate be removed from the market. The petition cites 200 studies, which represent a fraction of the independent scientific literature on the hazards of glyphosate and formulation ingredients of glyphosate products. This action follows previous litigation in 2022 in which a federal court of appeals struck down EPA’s human health assessment, finding that the agency wrongfully dismissed glyphosate’s cancer risk. The farmworker groups petitioning include Farmworker Association of Florida, OrganizaciĂłn en California de Lideres Campesinas, Alianza Nacional de Campesinas, and the Rural Coalition.   Meanwhile, verdicts against glyphosate’s manufacturer, Bayer, continue to pile up with a December jury verdict in Pennsylvania awarding $3.5 million and a November jury in Missouri ordering $1.56 billion to be paid to four plaintiffs. All link their cancer to use of the Roundup. Bayer has lost almost all of the cases filed against it for compensation and punitive damages associated with plaintiffs’ charge that its product (previously manufactured by Monsanto) caused them harm.  The petition summarizes its purpose and justification as […]

Int’l Group of Scientists Calls for Restraints on Conflicts of Interest in Publications and Regulation

(Beyond Pesticides, December 15, 2023) Drawing on a recent gathering of international scientists, a group of 34 scientists published a call for much stricter scrutiny of researchers’ conflicts of interest by agencies that regulate and register chemicals, with recommendations for the newly formed Intergovernmental Science Policy Panel. Writing in Environmental Science & Technology, the authors, led by Andreas Schäffer of Aachen University in Germany and Martin Scheringer of Masaryk University in the Czech Republic, cite an abundance of examples of chemical companies and their trade associations manufacturing doubt via an array of techniques, resulting in agencies such as the U.S. Environmental Protection Agency (EPA) dropping certain provisions from rulemaking, ignoring scientific consensus, and keeping chemicals on the market—and in the environment—that many scientists say should be entirely banned. The authors produced the article in response to this webinar to discuss how to ensure that U.N. panels dealing with global crises get the most sound scientific advice conducted by the International Panel on Chemical Pollution. Over the last four decades or so, the notion that conflicts of interest affect the validity of scientific research and professional opinions has been steadily eroded. Regulators wallow in compromised research, hamstrung by political pressure and […]

EPA May Allow Highly Neurotoxic Insecticide, Aldicarb, for Citrus Despite Ban in 2010 for Same Use

(Beyond Pesticides, December 14, 2023) It has been reported that the U.S. Environmental Protection Agency (EPA) is again considering allowing the use of the highly neurotoxic, carbamate insecticide aldicarb for use in Florida citrus, 13 years after the agency and the chemical’s manufacturer, Bayer Crop Science, announced that it was being banned (technically voluntarily canceled). A version of the current EPA proposal and the resource-intensive review process in EPA’s Office of Pesticide Programs—all being done at taxpayers’ expense—was rebuffed, first by the Florida Department of Agriculture and Consumer Services (April 2021), then by a U.S. Court of Appeals (June 2021). Internal EPA emails, as reported in The New Lede (November 21, 2023), expose the extent to which the agency’s science and political staff have tried to downplay aldicarb’s adverse health and environmental outcomes in order to meet the EPA’s broad, and often described as loose, risk parameters.  This Daily News piece on aldicarb is part of an ongoing story of the politicization of science by political appointees to an agency that is charged with protecting public health and the environment.

Pesticides Used in Production of Baby Food Ingredients Raise Alarm. . . Again

(Beyond Pesticides, December 8, 2023) Nine pesticides have been found in nearly 40% of nonorganic conventional baby foods tested, according to a study conducted by Environmental Working Group (EWG). The study found no residues of the pesticides studied in a sample of certified organic baby food. While the study finds no traces of the highly neurotoxic insecticide chlorpyrifos, associated with brain damage in children, the chemical has been allowed back on the agricultural market after being removed in 2021—raising an alarm for parents who purchase baby food with ingredients grown in chemical-intensive (“conventional”) agriculture. In November 2023, a three-judge panel of the Eighth Circuit Court of Appeals reversed a 2021 U.S. Environmental Protection Agency (EPA) decision to ban chlorpyrifos’ agricultural uses, which came after a 2021 Ninth Circuit Court of Appeals decision found that the agency’s inaction violated federal pesticide law. Because of its neurotoxic effects on children, EPA had in 2000 negotiated Dow Chemical’s voluntary cancellation of most residential uses of the chemical, but left virtually all of the chemical’s agricultural uses in place. While the EWG study focuses on pesticide residues in food and the hazards associated with ingestion of dangerous chemicals, raising alarms, purchasing baby food processed with nonorganic […]

Paraquat—The Continuing Environmental Threat Among All Species

(Beyond Pesticides, December 7, 2023) A new review published in Ecotoxicology reiterates what past studies have repeatedly stated: the herbicide paraquat (PQ) has profound adverse effects on wildlife at environmentally relevant concentrations. Moreover, these adverse effects span beyond the wilderness, as exposure to this highly toxic herbicide also impacts the health of people working with this chemical (e.g., pesticide applicators) or living adjacent to areas of chemical use. Current data gaps regarding the effects of environmentally relevant concentrations and exposure times, population- or ecosystem-level effects, and biomagnification potential contribute to the uncertainty of predicting risk from environmental PQ exposure. Furthermore, Beyond Pesticides has previously pointed out deficiencies in the U.S. Environmental Protection Agency’s (EPA) ecological risk assessments for paraquat, highlighting failures to perform complete evaluations of the impacts of pesticides on threatened and endangered species. All this occurs amid documented threats to biodiversity from the combined effects of pesticides and climate change.  The review investigated paraquat in the environment, the chemical’s toxicity to nontarget species, and significant data gaps. Overall, the long-term risks of environmental PQ contamination for human and ecological communities can be challenging since the potential chronic effects from extended use are nearly unstudied. Most concerning is that PQ is […]

Prenatal and Early Life Exposure to Glyphosate Herbicides Induce Hormonal Effects Disrupting Sleep and Neurodegenerative Diseases

(Beyond Pesticides, December 6, 2023) A study published in Antioxidants finds prenatal and early life exposure, usually after birth (perinatal), to glyphosate-based herbicides (GBH) induce oxidative stress in the brain, causing damage and negatively affecting melatonin levels. Melatonin is a hormone responsible for regulating circadian rhythm to mitigate sleep disorders. Disruption of melatonin levels also has implications for the development of age-associated neurodegenerative diseases, as melatonin is a neuroprotector against neurodegenerative diseases associated with aging. Additionally, GBH can alter molecules in the pineal gland in the brain, resulting in neurodegenerative diseases like Alzheimer’s disease (AD) and Parkinson’s disease (PD). Levels of inadequate sleep patterns are rising among the global population. Reports find variability in sleep duration results in higher rates of depression, anxiety, and fatigue. Since sleep is an essential factor in normal brain development, disturbance in sleep patterns, such as sleeping too much or too little, can result in long-term associations with the brain’s white matter integrity (responsible for age-dependent cognitive function). The study warns, “Since decreased levels of the important antioxidant and neuroprotector melatonin have been associated with an increased risk of developing neurodegenerative disorders, this demonstrates the need to consider the melatonin hormone system as a central […]

Study Finds Novel Relationship Between Shingles and Pesticide Exposure

(Beyond Pesticides, November 29, 2023) A study published in Environment International finds high pesticide exposure incidence associated with shingles, a varicella-zoster virus (the same highly contagious virus that causes chickenpox) that reactivates in the body after having chicken pox. Shingles is a painful condition with a blistering rash that can lead to vision and hearing loss, brain and lung inflammation, and even death if not treated. Since shingles manifest decades after initial exposure, and the association is strongest among individuals already hospitalized for pesticide-related illnesses, researchers find the long-term/chronic effects most concerning. Although dermal pesticide exposure can cause a range of adverse reactions, including dermatitis, allergic sensitization, and cancer, any route of exposure can exacerbate dermal manifestations through immune system response, causing virus-based skin reactions like shingles. People encounter toxic chemicals daily. However, frequent use of pesticides, including the use of everyday products like cleaning supplies, personal care products, agricultural chemicals, fabrics, non-stick cookware, and general airborne pollution, exacerbate chemical exposure risks. Dermal exposure is the most common pesticide exposure route, composing 95 percent of all pesticide exposure incidents, and is a significant concern for occupational (work-related) health. The study notes, “[The] findings of elevated shingles risk associated with acute, clinically relevant pesticide exposures also highlights […]

Plant-Based Diets: Beneficial for the Environment But Potentially High in Pesticides?

(Beyond Pesticides, November 21, 2023) According to a study in the Scientific Reports Journal, plant-forward diets might increase exposure to pesticide residues compared to meat-heavy diets. However, a switch to organic plant-based options significantly reduces this risk, with a separate research study indicating that vegetarians and vegans—often favoring organic products—are generally less exposed to synthetic pesticides than omnivores. The study also corroborates other research emphasizing the environmental benefits of plant-based diets, advocating for policies that make organic plant-based foods more widely accessible and emphasizing their crucial role in enhancing both environmental and human health.   Plant-based diets are increasingly popular—and with good reason. The intensification of animal agriculture is a major cause of deforestation, greenhouse gas emissions, and high water usage. In particular, Brazil accounts for one-third of global tropical deforestation, with 80% of this deforestation in the Amazon due to cattle ranching. Additionally, animal products like fish, eggs, and meat, responsible for about 83% of land use, supply only 37% of the global protein. Numerous studies suggest that reducing meat and animal product consumption can significantly mitigate environmental impacts, particularly regarding land use and greenhouse gas emissions. However, managed grazing in organic animal agriculture reduces many of the hazards […]

Erectile Dysfunction Among Younger Males Linked to Pesticide Exposures

(Beyond Pesticides, November 16, 2023) A study published in the Journal of Endocrinological Investigation finds exposure to the insecticide chlorpyrifos and other organophosphates (OPs) has a positive association with the development of erectile dysfunction (ED). Erectile dysfunction, also known as impotence, is the difficulty of getting or keeping an erection. Despite occurring in males later in life (between 40 and 70 years), recent studies highlight this issue emerging among adolescents, highlighting possible hormone imbalances not associated with age. Scientists and health officials already associate pesticide exposure with a decrease in male fertility, including reduced sperm count, quality, and abnormal sperm development. Exposure to many pesticides also profoundly impacts the endocrine (hormone) system, including reproductive health. Globally, ED is increasing, with over 300 million men expected to have ED by 2025. Although age and comorbid conditions (e.g., obesity, diabetes, and hypertension) play a role in ED prognosis, studies, including this one, suggest environmental contaminant exposure can also explain the increasing trend in ED. The study notes, “Future studies are warranted to corroborate these findings, determine clinical significance, and to investigate biological mechanisms underlying these associations.” Using data from the National Health and Nutrition Examination Survey (NHANES), researchers investigated urinary levels of 3,5,6-trichloro-2-pyridinol (TCPy), […]
