 (Beyond Pesticides, March 14, 2024) A recent review in the New England Journal of Medicine (NEJM) highlights the urgent need to address the widespread chemical pollution stemming from the petrochemical industry, underscoring the dire implications for public health. Tracey Woodruff, PhD, author and professor at the University of California San Francisco (UCSF), emphatically states in an email comment to Beyond Pesticides, “We need to recognize the very real harm that petrochemicals are having on peopleâs health. Many of these fossil-fuel-based chemicals are endocrine disruptors, meaning they interfere with hormonal systems, and they are part of the disturbing rise in disease.” Beyond Pesticides echoes this concern, noting that endocrine disrupting chemicals (EDCs) include many pesticides and are linked to a plethora of health issues such as infertility, diabetes, cardiovascular diseases, obesity, early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinsonâs, Alzheimerâs, and childhood and adult cancers. (See Beyond Pesticidesâ Disease database here and news coverage here). The review further calls on the clinical community to advocate for policy changes aimed at mitigating the health threats posed by petrochemical-derived EDCs and climate change. Beyond Pesticides urgently calls for the elimination of petrochemical pesticides and fertilizers and advocates for a systemic […]

(Beyond Pesticides, February 6, 2024) A study published in Occupational and Environmental Medicine finds that pesticide exposure, especially during puberty, can play a role in ovarian cancer development among female farmers. Although there are many studies that evaluate the risk for cancers among farmers, very few pieces of literature cover the risk of ovarian cancer from pesticide exposure. Additionally, this study notes suggests the role of hormones in ovarian cancer prognosis and development, highlighting an association with endocrine disruption. Exposure to past and current-use endocrine-disrupting chemicals (EDCs), like pesticides, has a long history of severe adverse human health effects. Endocrine disruptors are xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem) present in nearly all organisms and ecosystems. The World Health Organization (WHO), European Union (EU), and endocrine disruptor expert (deceased) Theo Colborn, Ph.D., classify over 55 to 177 chemical compounds as endocrine disruptors, including various household products like detergents, disinfectants, plastics, and pesticides. Endocrine disruption can lead to several health problems, including hormone-related cancer development (e.g., thyroid, breast, ovarian, prostate, testicular), reproductive dysfunction, and diabetes/obesity that can span generations. Therefore, studies related to pesticides and endocrine disruption help scientists understand the underlying mechanisms that indirectly or directly cause cancer, among other health issues. The study evaluates a […]

(Beyond Pesticides, February 5, 2024) Public Comment Period Ends February 26, 2024. The U.S. Environmental Protection Agency (EPA) never completed protocol for testing pesticides that disrupt the fundamental functioning of organisms, including humans, causing a range of chronic adverse health effects that defy the common misconception that dose makes the poison (âa little bit wonât hurt youâ)âwhen, in fact, minuscule doses (exposure) wreak havoc with biological systems. After a nearly two decade defiance of a federal mandate to institute pesticide registration requirements for endocrine disruptors, EPA has now opened a public comment period ending February 26, 2024 and advocates are criticizing the agencyâs proposed evaluation as too narrow. A detailed examination of EPA’s proposal can be found in draft comments by Beyond Pesticides. Endocrine disruption as a phenomenon affecting humans and other species has been critically reviewed by many authors. Endocrine disruptors are chemicals that can, even at extremely low exposure levels, disrupt normal hormonal (endocrine) function. Such endocrine disrupting compounds (EDC) include many pesticides, exposures to which have been linked to infertility and other reproductive disorders, diabetes, cardiovascular disease, obesity, and early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinsonâs, Alzheimerâs, and childhood and adult cancers. EPA […]

(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 glyphosateâas 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 […]

(Beyond Pesticides, January 4, 2024) A review published in the Journal of Neurosciences in Rural Practice finds an association between farmersâ 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 Alzheimerâs, amyotrophic lateral sclerosis (ALS), and Parkinsonâs disease. The researchers reviewed scientific articles published in […]

(Beyond Pesticides, January 3, 2024) A study published in Environmental Health Perspectives finds elevated, chronic exposure to glyphosate throughout oneâs 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 Agencyâs (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%) […]

(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 EPAâs human health assessment, finding that the agency wrongfully dismissed glyphosateâs 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 glyphosateâs 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 plaintiffsâ charge that its product (previously manufactured by Monsanto) caused them harm. The petition summarizes its purpose and justification as […]

(Beyond Pesticides, December 4, 2023) With a history of neglect of farmworker protection in the workplace, advocates are pointing to the need for ensuring stringent enforcement of regulations that are expected to take effect under the Pregnant Workers Fairness Act (PWFA) this month. In addition to weak laws and protections that typically exempt farmworkers, enforcement for farmworker protections that do exist has been lacking. A report on enforcement of wage and hour law under Wage and Hour Division of the U.S. Department of Labor (DOL) has documented diminished capacity to detect and enforce against violations. A report by the Economic Policy Institute (2020) shows the dramatic failures of DOL, which is underfunded and understaffed to enforce the law. As the agency charged with operationalizing the new law to protect farmworkers, the Equal Employment Opportunity Commission (EEOC)Â will be up against a federal pesticide law enforcement system that is dependent by agreements with state agencies, mostly departments of agriculture, that have a history of failing to enforce the limited protections provided for farmworkers. The EEOC is headquartered in Washington, D.C. and operates 53 field offices in every part of the country. Farmworkers have endured a long history of discrimination in the United […]

(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, âFuture studies are warranted to corroborate these findings, determine clinical significance, and to investigate biological mechanisms underlying these associations.â Using data from the National Health and Nutrition Examination Survey (NHANES), researchers investigated urinary levels of 3,5,6-trichloro-2-pyridinol (TCPy), […]

(Beyond Pesticides, August 23, 2023) Researchers are investigating a cutting-edge method to identify the impact of pesticides on reproductive healthâshrinking the wait time from months to weeks. Scientists at the University of California, Davis, are developing a method for identifying harmful chemicals in pesticides with the help of glowing fish. This scientific breakthrough could revolutionize pesticide research and help prevent long-term health problems caused by exposure to these chemicals. Pesticide exposure can cause acute and long-term health problems for the human endocrine system, the hormone system that regulates many biological processes from reproduction to blood sugar, growth, and more. Beyond Pesticides has written about the connections between EPA-registered pesticides and involuntary abortions, reproductive cancers, pregnancy loss, early-onset puberty, and more.  The American Academy of Pediatrics (AAP) has expressed concern over the limited or missing data regarding the health effects of pesticides and food additives on infants and children, who are more vulnerable to chemical exposures. AAP has identified several compounds as being of particular concern, including bisphenols, which are commonly used in the lining of metal cans; phthalates, which are used in adhesives and plasticizers; nonpersistent pesticides, which have been addressed in a previous AAP policy statement; perfluoroalkyl chemicals (PFCs), […]

(Beyond Pesticides, July 31, 2023) As the national debates on the rights of women to make health decisions about their bodies in the context of abortions, the scientific literature is increasingly documenting involuntary spontaneous abortions and other reproductive effects associated with pesticide exposureâraising critical questions about the ability to control oneâs health. Last week, Beyond Pesticides reported on an exploratory study, published in Environment International, that adds to the many studies demonstrating residential prenatal pesticide exposure can result in adverse birth outcomes. Residential exposure to five active pesticide ingredients (Ais) fluroxypyr-meptyl, glufosinate-ammonium, linuron, vinclozolin, and picoxystrobin has adverse effects on gestational age (GA), birth weight (BW), mortality after birth, childâs sex, premature development, low birth weight (LBW), small for gestational age (SGA), and large for gestational age (LGA). Despite the political furor surrounding medical abortions, the U.S. Environmental Protection Agency (EPA) continues to allow pesticides that cause involuntary spontaneous abortions (miscarriages) and other reproductive effects in exposed women. Tell EPA to ban pesticides that cause involuntary spontaneous abortions (miscarriages) and other reproductive effects. Tell Congress to ensure that EPA does not permit the use of pesticides affecting reproduction. Most spontaneous abortions occur during the first trimester. The most common cause of miscarriage during the first […]

(Beyond Pesticides, July 26, 2023) An exploratory study published in Environment International adds to the many studies demonstrating residential prenatal pesticide exposure can result in adverse birth outcomes. Residential exposure to five active pesticide ingredients (Ais) fluroxypyr-meptyl, glufosinate-ammonium, linuron, vinclozolin, and picoxystrobin has adverse effects on gestational age (GA), birth weight (BW), mortality after birth, childâs sex, premature development, low birth weight (LBW), small for gestational age (SGA), and large for gestational age (LGA). Pesticidesâ presence in the body has implications for human health, especially during vulnerable life stages like childhood, puberty, pregnancy, and old age. Pesticide exposure during pregnancy is of specific concern as health effects for all life stages can be long-lasting. Birth and reproductive complications are increasingly common among individuals exposed to environmental toxicants like pesticides. The Centers for Disease Control and Prevention (CDC) reports birth defects are the leading cause of infant mortality, with one in every 33 infants born with an abnormality that results in death. Therefore, studies like this can help government and health officials safeguard human health by assessing adverse effects following prevalent chemical exposure. Using a Dutch birth registry from 2009 to 2013, the researchers selected pregnant mothers over 16 years who were living in non-urban areas (who […]

(Beyond Pesticides, July 13, 2023) A study published in Environmental Science and Pollution Research finds exposure to p-Dichlorobenzene (p-DCB), a chlorophenol compound with uses as an insecticide, disinfectant, repellent, fumigant, fungicide, and deodorizer, can increase the risk of common endocrine (hormone)-mediated reproductive cancers (i.e., breast, uterine, and ovarian) in women. P-DCB or paradichlorobenzene has carcinogenic (cancer-causing) properties and the chemical has been banned in the European Union (EU) since 2005 for air fresheners and 2008 for mothballs. Being a chlorinated aromatic hydrocarbon (with benzene) compound (chlorobenzene), in addition to its cancer-causing properties, p-DCB can cause acute illnesses like headaches, numbness, sleepiness, nausea and vomiting and chronic effects like nervous system disorders leading to depression, and impact on the brain, birth outcomes, reproductive system, liver, and kidneys. Pesticides have a long history associated with endocrine-disrupting properties that induce various molecular changes, prompting disease development. Adding to the science, a similar review published in Environmental Exposure, Biomonitoring, and Exposure Assessment highlights how specific estrogen-mimicking pesticides increase the risk of disease, particularly hormone-related cancers among women (e.g., breast, ovarian, and endometrial cancer) and men (i.e., testicular, prostate cancer).PDCB, also known as para-dichlorobenzene, contains the carcinogen benzene and is chlorine-based (a chlorinated aromatic hydrocarbon compound), which in December 2019 […]

(Beyond Pesticides, July 6, 2023) A study published in Environmental Health Perspectives finds concentrations of organophosphate (OP) metabolites in urine during the prenatal phase have links to adolescent/young adult externalizing (e.g., hyperactivity, aggression, attention problems) and internalizing (e.g., depression) behavior problems. Thus, prenatal exposure to OP pesticides can permanently affect behavioral health as children mature into adulthood. This study adds to the growing body of research reinforcing the adverse effects of organophosphate (OP) exposure on cognitive health and neurological development, especially for infants and children. Prenatal development is one of the most vulnerable periods of exposure, as the fetus is most susceptible to the harmful effects of chemical contaminants. Many studies indicate that prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. Given research links to pesticide exposure and neurological and cognitive development, studies like this can help government and health officials identify how pesticidesâ impact on the brain elevates health concerns. Researchers gathered two urine samples from mothers during pregnancy (at weeks 13 and 26) and five urine samples from offspring from the ages of six months to five years old to measure urinary dialkylphosphates (DAPs) (nonspecific OP metabolites). Subsequently, the study also assesses reports of […]

(Beyond Pesticides, June 29, 2023) In the first major settlement amid an influx of PFAS litigation, industrial chemical giants DuPont, Chemours, and Corteva will pay $1.185 billion dollars to cities and towns across the U.S. to cover the cost of PFAS remediation and monitoring in public drinking water systems. The significance of this nationwide class-action settlement cannot be overstated, as citizens have battled powerful chemical corporations for decades with limited success. Dangerous toxicants have been indiscriminately discharged into the environment by chemical companies since the mid-1900s, and the PFAS litigation is important in the companyâs acceptance of responsibility for contamination. Of course, the damage to health and the environment is incalculable, given the pervasive environmental contamination and poisoning that it has caused, and additional lawsuits are pending, with more expected. Advocates maintain that this case exemplifies the inadequacies of regulatory controls that do a poor job of capturing the long-term effects of chemicals before being introduced into the market and a worse job of questioning the essentiality of toxic substances for which there are alternative practices and products. PFAS bring into sharp focus the legacy of chemical contamination and the impact on  future generationsâa problem well-documented with pesticides like DDT […]

(Beyond Pesticides, June 14, 2023) A study published in Scientific Reports finds a link between pesticide exposure and recurrent pregnancy loss (RPL) through oxidative stress and apoptosis (cell death) in the placenta. Recurrent pregnancy loss (RPL) is the loss of three or more successive pregnancies before 24 weeks of gestation (pregnancy) and signifies an underlying reproductive health issue. The study highlights that pesticides’ endocrine-disrupting (ED) properties can have varying adverse impacts on biological processes, including immunology, metabolism, and reproduction. Pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known pollutants (e.g., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals with ED properties that can move from the mother to the developing fetus at higher exposure rates. Additionally, pregnant women are experiencing exposure to an increasing number of dangerous industrial chemicals. With a range of scientific data highlighting chemical exposures during pregnancy as a critical window of vulnerability, public awareness of these threats is growing. The study notes, “They are associated with an increasing placental OS [oxidative stress] and placental apoptosis. Specific measures should be taken to decrease maternal exposure to these pollutants’ sources, especially in underdeveloped and developing countries.” For RPL, the research investigated pesticide components in blood plasma, […]

(Beyond Pesticides, May 31, 2023) A study published in Chemosphere supports accumulating scientific research confirming that prohibited and current use pesticides are readily detectable in the human placenta. All pregnant women experience exposure to a mixture of complex pesticides like DDT (prohibited organochlorine pesticide [OCP]) and chlorpyrifos (current use organophosphate [OP]), with concentrations high enough to increase possible adverse health risks to the fetus through a placental transfer of chemicals. Prenatal development in the intrauterine environment is one of the most vulnerable periods of exposure, as the fetus is most susceptible to the harmful effects of chemical contaminants. Many studies indicate that prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. Given the over 1,300 research studies that demonstrate the link between pesticide exposure and general health effects, studies like this can help government and health officials identify how pesticidesâ impact on the body elevates health concerns, especially for future and developing generations. The authors note, âThis study highlights the urgent requirement for implementing alternative pest-control methods in agriculture, involving a reduction of chemical pesticides application. Due to the vital role of the placenta in fetal development and its non-invasive sampling, this kind of […]

(Beyond Pesticides, May 5, 2023) Low level exposure to pyrethroid insecticides found in common pesticide brands like RAID and ORTHO result in neurodevelopmental damage to laboratory animals, reinforcing evidence of harm found in epidemiological studies on human exposure to these chemicals. According to research published in PNAS Nexus, mice exposed to the pyrethroid deltamethrin displayed atypical behavior similar to humans with developmental disorders. âWe are not saying these mice have autism or that they have ADHD. That’s not the goal here,â said James Burkett, PhD, study coauthor and assistant professor of neuroscience in the UToledo College of Medicine. âWhat we are saying is that something in their brain has been altered by this exposure and it’s resulting in the same kinds of behaviors that we see in children with autism.” Scientists arrived at this determination by exposing a group of mouse mothers to consistent low levels of deltamethrin in their food during preconception, pregnancy, and lactation. The study notes that the amount of pesticide provided was âwell below the benchmark dose for regulatory guidance.â A separate control group was given no pesticide in its food. Offspring from the female mice were then put through behavioral tests on social behavior, restrictive […]

(Beyond Pesticides, January 4, 2022) A study published in Environmental Science and Technology finds neonicotinoids (neonics) and their breakdown products (metabolites), like other chemical pesticide compounds, can readily transfer from mother to fetus. The National Health and Nutrition Examination Survey (NHANES) finds U.S. pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known pollutants (i.e., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals that can move from the mother to the developing fetus at higher exposure rates. Hence, prenatal exposure to these chemicals may increase the prevalence of birth-related health consequences like natal abnormalities and learning/developmental disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Moreover, a motherâs pesticide exposure can have a stronger association with health disorders than childhood exposure, and a newborn can still encounter pesticides. Therefore, it is essential to understand how pesticides impact the health and well-being of individuals during critical developmental periods. Beyond Pesticides has covered a variety of pregnancy risks from pesticides and other toxic chemicals, including these in just the last three years: pesticides and childrenâs sleep disorders; prenatal exposures to a multitude of chemicals; insecticides and childhood leukemia; insecticides and Attention Deficit/Hyperactivity Disorder. The study […]

(Beyond Pesticide, December 20, 2022) A meta-analysis published in Chemosphere finds prenatal pesticide exposure, or pesticide exposure during pregnancy has a positive association with autism spectrum disorder (ASD) and attention deficit/hyperactive disorder (ADHD). Particularly, exposure to chemical classes organophosphate (OP) and pyrethroid (PYR) insecticides, in addition to the motherâs age during pregnancy (âĽ30 years old), increased the risk factor of ASD. ADHD risk increases among offspring whose mothers encounter organochlorine pesticides (OCPs) during gestation. The etiology or cause of ASD and ADHD involves the interaction of multiple components, including lifestyle and genetics. However, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, solvents, dietary residues, etc.) play a role in disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues resulting in chronic health effects. ADHD is estimated to affect 8-12% of school-age children worldwide. While it is a complex disease, and genetics may play a role, no specific genes have been identified, and there is increasing evidence that environmental factors like pesticide exposure facilitate the development of the condition. Additionally, U.S. Centers for Disease Control and Prevention (CDC) estimates that 1 in 54 children have been diagnosed with an autism spectrum […]

(Beyond Pesticides, December 8, 2022) Children with higher levels of certain pesticide metabolites are more likely to go through early puberty, according to research published recently in Environmental Pollution. The findings by a team of Spanish researchers speak to a need for greater protections for children from toxic pesticide exposure. Children are much more sensitive to pesticide exposure than adults as they take in greater amounts of toxics relative to their body weight and have developing organ systems. Managing homes and yards without chemicals and purchasing organic food whenever possible can significantly reduce childhood pesticide exposure. Â Researchers began their investigation with children aged 7-11 participating in the Spanish stateâs Environment and Childhood multicenter birth cohort stud, an ongoing project aimed at understanding the effect of environmental exposures on pregnancy, fetal, and childhood development in the country. Out of over 3,000 children enrolled in the project, 1,539 had their urine sampled for the presence of pesticide metabolites. Scientists focused on four insecticides breakdown productsâa chlorpyrifos metabolite âTCPyâ, a metabolite of the organochlorine diazinon âIMPyâ, a general organophosphate metabolite âDETPâ, the pyrethroid metabolite â3-PBAâ, and a metabolite of ethylene-bis-dithiocarbamate fungicides âETUâ. Urinary levels of these pesticide metabolites were then compared against […]

(Beyond Pesticides, November 29, 2022) Based on new international research adding weight to previous research on falling sperm counts, it is critical that environmental agencies address this and other problems related to endocrine disruption. The study by Levine et al. finds that the drop in sperm countâa drop of 51.6% from 1973 through 2018âis global and that the rate of decline is accelerating. Tell EPA and Congress that pesticide use cannot continue without findings of no endocrine disruption. Â The documented (average) drop in sperm counts is approaching the level at which the ability to cause a pregnancy begins to plummet dramatically. The reduction in male fertility may have profound psychological and social impacts, including anxiety, low self-esteem, and depression. These psychological problems have health impacts of their own. Equally serious are connections of anxiety and depression with violent behavior and suicide. Compounding the problem is the fact that men are unlikely to seek fertility-related social support. The drop in sperm counts is just one example of endocrine disruption largely due to exposure to toxic chemicals. The endocrine system consists of a set of glands (thyroid, gonads, adrenal and pituitary) and the hormones they produce (thyroxine, estrogen, testosterone, and adrenaline), which […]
