(Beyond Pesticides, May 6, 2021) Nearly half of all breakdown products (transformation products) from four common-use environmental pesticides produce stronger endocrine (hormone) disrupting (ED) effects than the parent compound, according to new research published in Environment International. Over 300 environmental contaminants and their byproducts—from chemicals in plastics to cosmetic/personal care products—are commonly present in water bodies, food commodities, and human blood/urine samples. These toxicants can alter hormone metabolism, producing endocrine-disrupting effects that put the health of animals, humans, and the environment at risk. Many ecological and health risk assessments for pesticides focus on the effects of parent chemical compound products, overlooking the potential impacts of transformation products (TPs). Therefore, studies like these highlight the need to assess the implications of TPs to safeguard human, animal, and environmental health. The researchers note, “Since an increasing number of pesticide TPs have been detected in various environmental media, a more comprehensive understanding of the ecological risk of pesticide TPs is imperative for risk assessments more extensively and regulatory policy-making on pesticide restriction in the future.” Endocrine disruptors are xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem), including pesticides, bisphenols, phthalates, persistent organic pollutants (POPs), and heavy metals. Past research demonstrates exposure […]

(Beyond Pesticides, April 22, 2021) Past maternal exposure to the pesticide dichlorodiphenyltrichloroethane (DDT) during pregnancy can increase the risk of breast cancer and cardiometabolic disorders (e.g., heart disease, obesity, diabetes) up to three successive generations, according to a new study published in Cancer Epidemiology, Biomarkers & Prevention. Although previous studies highlight early life or in utero exposure to DDT increasing breast cancer risk later in life, this study is the first to note generational effects on grandchildren’s health. DDT continues to adversely affect the health of the U.S. population, nearly 50 years after its ban. However, this ban is not global, as many countries still use or manufacture the chemical compound. Furthermore, residues of DDT metabolite, DDE, continue to readily contaminate food and water worldwide. Therefore, studies like these highlight the need to investigate how first-generation pesticide exposure can impact future generational health in order to prevent adverse health outcomes, especially during sensitive developmental periods (i.e., in utero, infancy/childhood). The study researchers note, “Discovery of actionable biomarkers of response to ancestral environmental exposures in young women may provide opportunities for breast cancer prevention.” To assess the association between multi-generational health risks and chemical exposure, researchers used the Public Health Institute’s Child […]

(Beyond Pesticides, April 15, 2021) Gestational (during pregnancy) and childhood exposure to per- and polyfluoroalkyl substances (PFAS) increase cardiometabolic risk, or the risk of heart diseases and metabolic disorders, later in life, according to a Brown University study published in Environment International. Past studies associate exposure to chemical pollutants with increased susceptibility to adverse health effects during critical fetal and childhood developmental periods. Some of these health effects are cardiometabolic risk factors, including obesity, insulin issues, abnormal blood pressure, that increase the risk of developing cardiovascular disease (CVD) and metabolic disorders (e.g., type 2 diabetes). PFAS are of particular concern as these endocrine-disrupting chemicals are common in non-stick cookware, cleaning/personal care products, food packaging, and other consumer products. They are now being found in pesticide products. Because of their ubiquitous use in many products, studies report that PFAS compounds are detectable in infants, children, and pregnant women. Furthermore, pregnant women can readily transfer compounds to the developing fetus through the placenta. Cardiovascular disease and diabetes are among the leading causes of death globally. Additionally, heart conditions are one leading cause of disability in the U.S., as research demonstrates environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac […]

(Beyond Pesticides, April 5, 2021) The failure of EPA to meet its statutory responsibility to protect people and wildlife from the dire consequences of exposure to endocrine disrupting chemicals must end. Over recent decades, evidence has mounted showing that many pesticides interfere with hormones—and are therefore endocrine-disrupting chemicals (EDCs). In 1996, the promise of screening pesticides for endocrine disruption generated support from environmentalists and public health advocates for the Food Quality Protection Act (FQPA), which traded the absolute prohibition of carcinogens in food of the Delaney Clause for a risk assessment standard that is subject to manipulation and an underestimation of real-life hazards. And now, 25 years later, we have yet to see EPA use endocrine disruption findings in pesticide registration decisions. >>Tell EPA that pesticide use cannot continue without findings of no endocrine disruption. 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 help guide the development, growth, reproduction, and behavior of animals, including humans. Hormones are signaling molecules, which travel through the bloodstream and elicit responses in other parts of the body. More than 50 pesticide active ingredients have been identified as […]

(Beyond Pesticides, March 18, 2021) A new study published in Environmental Toxicology and Pharmacology finds chronic (long-term) organophosphate (OP) pesticide exposure increases adverse health and cancer risk for U.S. women relative to men. Organophosphorus pesticides have a wide range of biological uses—from insecticides to flame retardants—that make these chemicals ubiquitous, significantly contributing to ecosystem contamination. Furthermore, while organophosphates have less bioaccumulation potential, residues are consistently present in human and animal blood, urine, tissues, and milk. Although research demonstrates that OPs are highly toxic, there remains an inadequate understanding of how OP exposure impacts the nonagricultural population in the U.S., especially women. Therefore, it is essential to investigate the sex-specific health effects chemical contaminants can produce to mitigate exposure among vulnerable populations. Study researchers note, “Given the higher burden of OP exposure and their significantly higher overall health risk, including cancer, reducing OP exposure in U.S. women needs to be prioritized.” To examine the relationship between OP exposure and health risks, researchers investigated the presence of commonly detected OP metabolite concentrations in urine using participants from the U.S. National Health and Nutrition Examination Survey (NHANES). Urine samples measure OP metabolite as an indicator of OP exposure like previous agriculture-related population surveys. Study participants report health issues […]

(Beyond Pesticides, February 25, 2021) A University of Michigan study finds a link between elevated rates of breast cancer incidents and chemical exposure from pesticides among African American women. Breast cancer is the most common cancer among women, causing the second most cancer-related deaths in the United States. However, breast cancer outcomes differ significantly among women of various races/ethnicities, with African American women being 40 percent more likely to die from breast cancer than women of any other race. Furthermore, incidences of triple-negative breast cancer (TNBC)—an aggressive breast cancer subtype lacking remediation—is approximately three-fold higher in non-Hispanic Black women (NHBW) compared to non-Hispanic White women (NHWW). Although past studies suggest genetic and environmental factors interact to produce these differences in breast cancer outcomes, genetic factors only play a minor role while disparities (differences) in external factors (i.e., chemical exposure) may play a more notable role. This study highlights the significance of understanding how chemical exposure drives disease outcomes and increases disease risk, especially for more virulent diseases that disproportionately (unequally) impact specific communities. Prior research infers differences in chemical exposure may explain racial disparities for several illnesses, and growing evidence suggests common chemical exposure patterns influence the risk of breast cancer.

(Beyond Pesticides, February 11, 2021) California sea lions (Zalophus californianus) are experiencing high rates of urogenital carcinoma (UGC) cancer incidences from the combined effect of toxic “legacy” pesticides like DDT and the viral infection Otarine herpesvirus-1 (OtHV1), according to a new study published in Frontiers in Marine Science. Previous research documents the role herpesvirus infection, genotype, and organochlorine pesticides play in sea lion cancer development. However, synergism (collaboration) between viral infection and toxic chemical exposure increases cancer development odds. Pollution of the oceans with toxic chemicals lacks adequate regulation, is widespread and only getting worse. More than 80 percent of ocean pollution comes from land-based, anthropological activities. A recent study published in Annals of Public Health finds toxic chemicals from pesticides, heavy metals, plastics, and other sources readily contaminate the ocean, especially near coastal regions where chemical inputs occur in higher concentrations. Globally, pollution has major disease implications, causing the deaths of over nine million people annually. Therefore, it is essential to understand the co-effects of ocean pollution and diseases to protect human health. Authors of the study state, “This study has implications for human health, as virally associated cancer occurs in humans, and likelihood of cancer development could similarly be increased by exposure to environmental […]

(Beyond Pesticides, January 22, 2021) After the past four devastating years, hopes and expectations of the Biden/Harris administration abound among the environmental and public health communities. The ears and eyes of many advocates, as well as those in the agricultural community, are attuned (among myriad candidates) to the fate of the pesticide aldicarb. Although Environmental Protection Agency (EPA) registration of this terribly toxic insecticide was cancelled in 2010, various limited-use reapprovals since then have meant that the compound has found its way to increasing levels of use. On January 12, as another parting shot of midnight rulemaking, Trump’s EPA approved expanded uses (see below). The $64,000 question is whether the new administration will use its authority under the Congressional Review Act — which enables Congress to pass a joint resolution (then signed by the President) to overturn a new federal agency rule and prevent its reissuance in the future — to get this pesticide retired for good. Beyond Pesticides urges President Biden’s EPA to do so. Notably, the Trump administration used the Congressional Review Act to destroy myriad environmental rules when it came into power. This permitting of expanded aldicarb uses fits the pattern. Environmental Health News notes that, as of early […]

(Beyond Pesticides, December 23, 2020) The litany of parting shots by the waning Trump administration got longer on December 4, when the Environmental Protection Agency (EPA) announced a proposed interim decision on the very toxic pesticide chlorpyrifos, functionally continuing its registration for many agricultural uses. The interim decision purports to put in place new limitations on use of this pesticide, but they are wholly inadequate to the threat this compound represents — to young children, most concerningly, as well as to farmworkers, critical species and ecosystems, and the public. Chlorpyrifos should not be re-registered for use — i.e., its sale and use should be banned altogether, as Beyond Pesticides has asserted for years. Chlorpyrifos is an organophosphate pesticide used on scores of food crops, for mosquito (and other pest) control, and for some turf management (golf courses, especially). It has been demonstrated to be highly neurotoxic, especially to young children, leading to impaired cognitive function, developmental delays, lower IQs, attention deficit disorder, and a variety of other pervasive developmental and learning disorders. The essence of the compound’s toxicity to developing brains lies in its function as a cholinesterase inhibitor; chlorpyrifos binds to the receptor sites for acetylcholinesterase (AChE), an enzyme […]

(Beyond Pesticides, December 7, 2020) The Trump Environmental Protection Agency (EPA) reversed in four years much of the progress made by EPA in decades, and that push continues. The Biden EPA needs to advance a new vision. Tell President-elect Biden to adopt a new direction for pesticide regulation. Challenge so-called “benefits” of pesticides. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires EPA to weigh risks against benefits when registering pesticides. Claimed “benefits” for toxic pesticides need to be judged in comparison to organic production, which is able to produce all types of food and feed. The Organic Trade Association reports that organic sales now exceed $55 billion per year, and the U.S. Department of Agriculture (USDA) finds that organic producers in the U.S. produced $9.9 billion worth of organic food on 5.5 million acres in 2019. EPA assumes benefits of pesticides, rather than measuring them, and does not take into account the development of resistance. The cost-competitive success of organic food production and nonagricultural land management practices make the case that toxic pesticides lack benefits. Protect pollinators. Agriculture relies on insect pollinators to facilitate fertilization and maintain annual crop yield. Globally, the production of crops dependent on pollinators is worth […]

(Beyond Pesticides, December 4, 2020) Amid the maelstrom of national political news related to the recent election, and the Trump administration’s upcoming exit, comes a release of the Environmental Protection Agency’s (EPA’s) draft biological evaluation (BE) of glyphosate. The assessment indicates that use of this ubiquitous herbicide likely threatens nearly every animal and plant species on the U.S. list of threatened and endangered species — 93% of them, in fact. Chemical and Engineering News reports that the EPA announcement was made public only a few days after the agency also reported that atrazine (another commonly used and toxic herbicide) probably harms more than half of those species. Given the Trump EPA’s eagerness, during the past four years, to serve industry interests rather than protect human health, biodiversity, and functional ecosystems, the timing of this released evaluation during the so-called “lame duck” period is puzzling. Glyphosate is the active ingredient in many herbicides, including RoundupTM, Monsanto’s (now Bayer’s) ubiquitous and widely used weed killer; it is very commonly used with genetically modified companion seeds for a variety of staple crops, as well as for weed control on managed landscapes. These seeds are genetically engineered to be glyphosate tolerant. Glyphosate-based herbicides are the most […]

(Beyond Pesticides, November 18, 2020) The herbicide atrazine is likely to adversely affect over half of endangered species listed in the United States, according to a report released by the U.S. Environmental Protection Agency (EPA) as part of a legal agreement with the Center for Biological Diversity (CBD). Based on both adverse human health and environmental threats, Beyond Pesticides joined with Center for Food Safety, CBD, and other public-interest groups in October to sue EPA over its decision to reapprove atrazine, an endocrine-disrupting herbicide banned across much of the world. These actions follow the agency’s recent reapproval of atrazine, which reduced a number of safeguards for public health and the environment, and it’s enactment of rules that limit endangered species reviews. See (Lawsuit Challenges EPA Reapproval of Endocrine-Disrupting Pesticide Atrazine: Agency Slashes Protections for Children, Waterways.) Although advocates are hopeful that the next administration will shift toward an EPA that lives up to its namesake, there is considerable ground to make up. Atrazine is an herbicide that disrupts the endocrine system by mimicking the body’s natural hormones, binding to hormone receptors in the body. In humans, the effect can result in birth defects, damage to the reproductive system, and chronic […]

(Beyond Pesticides, November 6, 2020) Beyond Pesticides joined health and environmental groups suing the U.S. Environmental Protection Agency (EPA) late last month over its decision to reapprove the endocrine disrupting herbicide atrazine with fewer protections for children’s health. Despite the chemical being banned across much of the world, EPA continues to make decisions that benefit chemical industry executives. “EPA’s failure to remove atrazine represents a dramatic failure of a federal agency charged with safeguarding the health of people, wildlife, and the environment,” said Jay Feldman, executive director of Beyond Pesticides. “We seek to uphold the agency’s duty to act on the science, in the face of viable alternatives to this highly toxic weedkiller.” It is not hyperbole, but in fact scientifically documented, that atrazine exposure “chemically castrates” frogs, impairs fish reproduction, and can result in birth defects and cancer in humans. EPA decision comes on the heels of a rash of industry-friendly decisions. Within the last month, the agency has finalized rules weakening farmworker buffer zone protections, reapproving dicamba use on genetically engineered crops, and reregistering some of the most toxic pesticides on the market. The lawsuit, filed in the Ninth Circuit Court of Appeals, contends that before reapproving atrazine, […]

(Beyond Pesticides, October 19, 2020) The COVID-19 epidemic has made clear to the general public what we at Beyond Pesticides have been stressing since our inception—some populations have disproportionate risk of severe outcomes, exposures to toxic chemicals can affect susceptibility to disease, comorbidity increases risk, and bad government can kill you. As Trump declares that “unborn children have never had a stronger defender in the White House,” we are reminded of Erik Jansson, who ran the National Network to Prevent Birth Defects and helped to convene the founding meeting of Beyond Pesticides, and took on then-Administrator of EPA Anne Gorsuch, calling her a “baby killer” because of policies that allowed exposures to toxic chemicals—exposures that endangered children and fetuses. Those were harsh words in the 1980s even when the Reagan administration’s environmental and toxics policies were tied to elevated harm to people, and children in particular. In today’s world, scientists and medical doctors are regularly linking elevated death rates from coronavirus to the federal government’s inadequate coronavirus policy and its attack on science. And, they are pointing to those in charge. Policies and decisions under the Trump administration that threaten the health of children and the unborn include: COVID-19 misinformation. […]

(Beyond Pesticides, October 14, 2020) Exposure to certain endocrine disrupting pesticides increases the risk men, and Hispanic men in particular, will contract testicular cancer, according to research presented at the American Association for Cancer Research Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved. The data show that living near the use of the insecticide acephate presents the greatest cancer risk. “Testicular cancer rates have been rising for decades and are rising especially quickly among Hispanics in the United States,” said Scott Swartz, an MD candidate in University of California Berkeley-UCSF Joint Medical Program, to Healio. “Given that Hispanics are disproportionately exposed to many endocrine-disrupting pesticides in California, we were interested in investigating the potential effects of nearby endocrine-disrupting pesticide application on testicular cancer among Hispanics in California.” Using public health databases, researchers assessed a group of 381 men diagnosed with testicular cancer while 15 to 19 years old, during the years 1997-2011. This cohort was compared to a control group of 762 otherwise healthy men of similar age, race and ethnicity during the same time. California’s Pesticide Use Report system was used to analyze agricultural pesticide applications within 1.8 miles of a study […]

(Beyond Pesticides, October 2, 2020) The U.S. Environmental Protection Agency’s (EPA) September 22 announcement asserts that, “despite several years of study, the science addressing neurodevelopmental effects [of the insecticide chlorpyrifos] remains unresolved,” as reported in The New York Times. This conclusion contradicts both ample scientific evidence and the agency’s own findings. Beyond Pesticides has repeatedly advocated for a ban on the use of chlorpyrifos because of the grave risks it poses. This organophosphate pesticide is used on approximately 60 different crops, including almonds, cotton, citrus fruits, grapes, corn, broccoli, sugar beets, peaches, and nectarines. It is also commonly employed for mosquito-borne disease control, and on some kinds of managed turf, including golf courses. Exposure to the pesticide has been identified repeatedly as problematic. Most residential uses were taken off the market in 2000, after the manufacturer, DowDupont (now Corteva) was faced with EPA action. Chlorpyrifos is a cholinesterase inhibitor that binds irreversibly to the receptor sites of acetylcholinesterase (AChE), an enzyme that is critical to normal nerve impulse transmission. In so doing, chlorpyrifos inactivates the enzyme, damages the central and peripheral nervous systems, and disrupts neurological activity. The compound is associated with harmful reproductive, renal, hepatic, and endocrine disrupting effects, and most […]

(Beyond Pesticides, September 22, 2020) Use of the highly hazardous, endocrine disrupting weed killer atrazine is likely to expand following a decision made earlier this month by the U.S. Environmental Protection Agency (EPA). Under the guise of “regulatory certainty,” the agency is reapproving use of this notorious herbicide, as well as its cousins simazine and propazine in the triazine family of chemicals, with fewer safeguards for public health, particularly young children. Advocates are incensed by the decision and vow to continue to put pressure on the agency. “Use of this extremely dangerous pesticide should be banned, not expanded,” Nathan Donley, PhD, a senior scientist at the Center for Biological Diversity said in a press release. “This disgusting decision directly endangers the health of millions of Americans.” Beyond Pesticides has long argued against the continued use of the triazine herbicides, which includes atrazine. Triazines are well known to interfere with the body’s endocrine, or hormonal system. Disruptions within this delicately balanced process in the body can result in a range of ill health effects, including cancer, reproductive dysfunction, and developmental harm. These weedkillers interfere with the pituitary gland’s release of luteinizing hormones, which regulate the function of female ovaries and male gonads. In comments written by Beyond Pesticides to EPA, the organization notes, “Of the numerous adverse effects associated with this disruption, […]

(Beyond Pesticides, September 18, 2020) In late August, Consumer Reports magazine (CR) issued a report titled, “Stop Eating Pesticides,” which offers consumers a rating system CR developed and employed to help them “get the health benefits from fruits and vegetables while minimizing [the] risk from toxic chemicals.” In addition to providing its analysis and ratings of the pesticide risk of a variety of produce items, CR recommends eating organically grown and raised foods whenever possible. It also makes a host of recommendations on federal pesticide policies and emphasizes the importance of maintaining the integrity of the National Organic Standards (of the USDA-housed National Organic Program). Beyond Pesticides appreciates that this mainstream publication has arrived at many shared, science-based assessments of the risks of pesticides. That said, a wholesale transition to organic and regenerative agriculture — rather than making the public figure out which fruits and vegetables are “safer” or “less safe” — is the real answer to the health risks of pesticides in the food supply, according to Beyond Pesticides. The CR analysis used data from the U.S. Department of Agriculture’s (USDA’s) Pesticide Data Program for 2014–2018. Those pesticide residue data were compiled from tests of approximately 450 pesticides across 24,000 […]

(Beyond Pesticides, August 12, 2020) The herbicide atrazine can interfere with the health and reproduction of marsupials (including kangaroos and opossums) kangaroo, Virginia opossum, according to research published in the journal Reproduction, Fertility, and Development. Although the research focuses on the health of the Australian wallaby, the data is relevant for the only marsupial in the United States, the opossum. Unfortunately, the research is no surprise, as atrazine has a long history of displaying endocrine (hormone) disrupting properties, affecting sex and reproduction in a broad range of species. The study, under the auspices of University of Melbourne Animal Experimentation and Ethics Committee, exposed pregnant female adult wallabies to atrazine through gestation, birth, and lactation. Doses of the weedkiller were slightly higher than real world models, but according to researchers, “It is quite possible a wild animal could get such an exposure.” Researchers then euthanized the newborn wallabies to study atrazine’s effects. The gonads and phallus of young wallabies were analyzed for any physiological changes or impacts to gene expression. Researchers found changes to the gene expression necessary for basic function of the testis, and a significant reduction in phallus length. “These results demonstrate that [atrazine] exposure during gestation and lactation can […]

(Beyond Pesticides, August 7, 2020) Research out of the Silent Spring Institute identifies 28 registered pesticides linked with development of mammary gland tumors in animal studies. Study authors Bethsaida Cardona and Ruthann Rudel also report that many of the pesticides they investigated behave as endocrine disruptors; breast cancers in humans are significantly influenced by hormones generated by the endocrine system. The Environmental Protection Agency (EPA) acknowledges that nine of these 28 pesticide compounds cause mammary tumors, but dismisses the evidence of the other 19. The results of this research, published in the journal Molecular and Cellular Endocrinology, evince Beyond Pesticides’ long-standing argument that the risk assessment process used by EPA for its pesticide registration process is substantially inadequate to protect human health. The co-authors cite, as the catalyst for this research project, a Cape Cod resident’s outreach to the Silent Spring Institute several years ago, asking for information about the herbicide triclopyr because utility companies wanted to spray it on vegetation below local power lines. (The compound has also been used by the logging industry in the Pacific Northwest.) They reviewed more than 400 EPA pesticide documents on the health impacts of many registered pesticides for this research, conducted as part […]

(Beyond Pesticides, July 2, 2020) Exposure to low levels of endocrine-disrupting chemicals commonly in waterways, including pesticides, can impact future generations of major commercial fish, despite no direct exposure to the chemicals, according to research published in the journal Frontiers in Marine Science by Oregon State University (OSU) researchers. Many studies assess the acute or chronic health implications associated with endocrine disruptors on a single generation but lack information on multi-generational impacts that can provide vital information on the fundamental survivability or fitness of many species. This study highlights the significance of understanding the implications of endocrine disruptors, even at low levels of exposure, as parental exposure can have adverse epigenetic consequences for future generations. Kaley Major, a Ph.D. fellow at Oregon State University (OSU) and lead research author, explains, “What t[his] gets at is something your grandparents may have come into contact within their environment can still be affecting the overall structure of your DNA in your life today.” Endocrine disruptors are xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem). Past research shows exposures to endocrine-disrupting chemicals can adversely impact human, animal—and thus environmental—health, by altering the natural hormones in the body responsible for […]

(Beyond Pesticides, June 30, 2020) A review of scientific literature on the toxic effect of environmental contaminants—including pesticides—published in the journal Toxicological Science, “The Impact of Environmental Chemicals on the Gut Microbiome,” associates these chemicals to changes in the gut microbiome and other adverse health implications. The review, by researchers at the University of Illinois, looks at how environmental contaminants adversely effects and reinforce chemical disruption of the gut microbiome. It highlights the importance of evaluating how environmental contaminants, like pesticides, impact body regulation by gut microbiota. The study has significant implications for considerations that should be, but are not currently, a part of pesticide review and registration by the U.S. Environmental Protection Agency (EPA). Gut microbiota plays a crucial role in lifelong digestion, immune, and central nervous system regulation, as wells as other bodily functions. Through the gut biome, pesticide exposure can enhance or exacerbate, the adverse effects of additional environmental toxicants on the body. Since the gut microbiome shapes metabolism, it can mediate some toxic effects of environmental chemicals. However, with prolonged exposure to various environmental contaminants, critical chemical-induced changes may occur in the gut microbes, influencing adverse health outcomes. Karen Chiu, Ph.D., a graduate research fellow at the […]

(Beyond Pesticides, June 18, 2020) Residential exposure to household pesticide products increases the risk of developing symptoms associated with depression, according to a study published in Environmental Research by researchers at Medical College of Georgia—Augusta University, School of Medicine—Jinan University, and Guangzhou Center for Disease Control and Prevention (CDC), China. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses, and previous studies show there are occupational risks of developing depression, especially in agriculture where pesticide use is rampant. However, there is a lack of information connecting pesticide exposure to the subsequent psychological (psychiatric) effects on the general population. Additionally, household pesticide exposure varies from occupational exposure via exposure frequency, duration, intensity, and type. This research highlights the significance of researching potential mental health effects resulting from pesticide exposure, especially as society tends to rank mental health risks second to physical health. The study’s scientists note, “Our results highlight the importance of the cautious use of household pesticides because the chronic effects of poisoning may contribute to an elevated risk of depression.” According to the World Health Organization (WHO), depression affects 322 million people globally, with the number of diagnosed patients increasing by 18.4% from 2005 to 2015. Although the etiology of depression—and […]
