(Beyond Pesticides, July 16, 2024) Yet another study in the August 2024 journal Ecotoxicology and Environmental Safety has found that exposure to organophosphorus pesticides (OPPs) is correlated with increased suicidal thoughts in some people. This study is just the latest in a long line of studies from around the world that have linked pesticide exposure to mental health conditions, including sleep disorders, depression, and suicidal ideation (SI). As the rate of suicide increased by 30% between 2000 and 2020, there is an urgent public health need to investigate and address all potential contributing factors. A 2019 study, covered in Daily News, found that teens and adolescents living in agricultural areas and exposed to organophosphate (OP) insecticides are at higher risk of depression, In July and January this year, other studies link farmer psychiatric episodes to pesticide exposure, adding to the body of science. Exposure to household pesticides is also linked to depression in a 2020 study.   Study and Methodology  The study entitled “Association between exposure to organophosphorus pesticide and suicidal ideation among U.S. adults: A population-based study,” analyzes information on the mental and physical health of over 5,000 individuals aged 20 and up in the United States. The study aims […]

(Beyond Pesticides, July 2, 2024) Men’s Mental Health Awareness Month, which took place last month, evokes concern about the growing body of science linking pesticide exposure to neurological effects linked to depression. Recent studies reveal elevated rates of psychiatric disorders, including suicide, among farmers, with problems more common for males.  Through systematic reviews, meta-analyses, surveys and interviews, and blood sampling, these three studies add to the growing body of science linking pesticide exposure to neurological impacts. First, in the Journal of Agromedicine, researchers from Greece and the United Kingdom review eight studies and find a significant positive association between pesticide poisoning and depression in agricultural populations.1 Second, a study in Toxicology shows a link between depression in Brazilian farmers and pesticide exposure, most notably with glyphosate usage.2 Third, the latest study in Environmental Toxicology and Pharmacology focuses on work by researchers from Spain in identifying farmers exposed to chlorpyrifos, mancozeb, and malathion that have higher rates of depressive symptoms and suicide attempts.3  Through a meta-analysis of published research, the authors of the Agromedicine journal article identify pesticide poisoning as a risk factor of depression. With depression affecting more than 264 million individuals worldwide, this is a field of interest with […]

(Beyond Pesticides, May 8, 2024) In an unexpected turnaround, the U.S. Environmental Protection Agency (EPA) announced at the end of April a Proposed Interim Decision (PID) to discontinue all but one application of the insecticide acephate. Acephate is an organophosphate pesticide, a well-known neurotoxicant, widely banned globally, including in the European Union. Under the proposal, all uses would end except for the injection of trees that do not produce fruit or nuts. In its proposed action, EPA asks the manufacturer to offer the agency a voluntary settlement, a process that typically compromises the health of the public, workers, and the environment. Acephate, an organophosphate (OP) pesticide, is approved for use in both agricultural settings, including crops like cotton and soybeans, and nonagricultural applications, such as injections for forestry trees. Acephate affects the nervous system by inhibiting the acetylcholinesterase (AChE) enzyme. Importantly, chronic, low levels of exposure can cause a range of adverse human health outcomes, from cancer to birth defects, reproductive and developmental problems, and learning disabilities. While the proposed April interim decision, if it comes to pass, is welcomed by advocates, some are concerned that EPA’s proposal does not fully critique the scientific documents and conclusions on risk that […]

(Beyond Pesticides, May 3, 2024) Parkinson’s disease (PD) is the second most common neurodegenerative disease in the world after Alzheimer’s. Genetic factors account for only a fraction of PD cases, and for decades scientists have been aware of associations between pesticide exposures and PD. Yet, not everyone exposed to pesticides gets PD. Consequently, neither the genetic nor the environmental hypothesis is fully satisfactory; both may be involved. Thus, there has been great interest in identifying gene variants that affect the risks of PD associated with pesticide exposure. Now a team of University of California at Los Angeles researchers led by neurologist Brent Fogel, MD, PhD has traced a connection between certain gene variants and the occurrence and severity of PD in a cohort of central California PD patients who have had long-term exposure to pesticides. The genes are related to autophagy, the process by which cells organize, degrade, recycle or eject molecules to maintain healthy chemical balance. Autophagy is an essential process throughout the body, including regulation of mitochondria, which are also vital for healthy cellular function. The study supports other research suggesting that autophagy is disturbed in neurodegenerative diseases. As Beyond Pesticides discussed in its April 19 Daily News, PD […]

(Beyond Pesticides, January 5, 2023) The 28th United Nations Climate Change Conference of the Parties (COP28) wrapped up in Dubai on December 13 with what some hailed as a breakthrough agreement among almost 200 countries to reduce fossil fuel consumption that signals “the eventual end of the oil age.” To be successful and assure human survival, eliminating oil, gas, and coal use, Beyond Pesticides is calling for the elimination of petrochemical pesticides and fertilizers and support for organic, regenerative agriculture around the world. Because of the insurmountable crises that are caused or exacerbated by petrochemical pesticides and fertilizers, the adoption of organic land management practices and the need for foundational change in federal, state, and local policies and practices has come into focus. Under organic management, healthy soil can absorb and store 1,000 pounds of carbon per acre foot of soil annually. This translates to about 3,500 pounds of carbon dioxide per acre drawn down from the air and sequestered into organic matter in soil. (It is noteworthy that use of synthetic fertilizers actually compromises the carbon-capture ability of some kinds of terrain, such as salt marshes.) A fact often overlooked by policy makers in generating climate strategies is that carbon-sequestering soil practices […]

(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), […]

(Beyond Pesticides, November 14, 2023) One of the Environmental Protection Agency’s (EPA) strongest tools for avoiding responsibility is delay—a tactic that kept cancellation of the neurotoxic pesticide chlorpyrifos at bay for 21 years—until May 2021, when a three-judge panel of the Ninth Circuit Court of Appeals, responded to a petition filed in 2007 by the Natural Resources Defense Council, Pesticide Action Network, and numerous other groups. The Ninth Circuit ordered the agency to quit lollygagging and acknowledge chlorpyrifos’s threat to human health, something the agency had acknowledged already. The Ninth Circuit instructed EPA to either revoke the “safe” tolerances the agency had set for chlorpyrifos’s residue in various foods or demonstrate that they are actually safe. Finally capitulating, EPA issued a final rule in August 2021 revoking all food tolerances for the neurotoxicant. Tell your governor and mayor to adopt policies that support organic land management.  This looked like progress until February 2022, when a different set of petitioners—pesticide companies, U.S. farmer groups, and other countries’ agricultural interests—filed an action in the Eighth Circuit Court of Appeals. On November 3 of this year, a three-judge panel of the Eighth Circuit reversed EPA’s decision, thereby neutralizing the Ninth Circuit’s opinion. Chlorpyrifos, […]

(Beyond Pesticides, November 8, 2023) A study published in Environmental Science and Pollution Research finds organophosphate pesticides (OPs) are linked to an increased asthma prevalence. The study was released just before an 8th Circuit U.S. Court of Appeals November 3 decision vacating EPA’s 2021 decision to cancel all food tolerances for chlorpyrifos and sending it back to the agency. (Required by a 9th Circuit Court of Appeals decision in April 2021 to take action, EPA issued a final rule in August, 2021—in full effect February 28, 2022—after an earlier 9th Circuit decision, concluding that, “EPA is unable to conclude that the risk from aggregate exposure from the use of chlorpyrifos meets the safety standard of the Federal Food, Drug, and Cosmetic Act (FFDCA). Accordingly, EPA is revoking all tolerances for chlorpyrifos.”  Using urinary metabolites of OPs, the study highlights that diethyl phosphate (DEP, the breakdown chemical of chlorpyrifos) has the strongest association with asthma. However, individual and combined exposure to all OPs have a significant link to respiratory disease. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal function. Damage to the respiratory system can […]

(Beyond Pesticides, October 4, 2023) A study published in Food and Chemical Toxicology finds acute exposure to chlordane, an organochlorine insecticide, results in decreased lipid (fat) levels, altered anti-oxidant capacity, and increased testosterone levels (pro-androgenic) in male mice, while increasing liver enzyme activation and reducing regulation of both liver identity and function in females. These findings indicate that chlordane induces toxicant-associated steatosis (fat retention) liver disease (TASLD) with underlying, sex-specific, endocrine, and metabolic effects. It is well-known that traces of legacy (past-use) pesticides, like organochlorine pesticides (OCPs), remain in the environment for decades—possibly centuries, post-final application, as OCPs have greater chemical stability and gradual attenuation. However, these chemicals have profound adverse impacts on human health, especially on the endocrine system. Obesity, insulin resistance, type 2 diabetes, and elevated liver enzymes resulting from endocrine disruption contribute to liver diseases and can lead to liver cirrhosis. Although some, but not all, manufacturing and use of specific OCPs have declined in the U.S., OCPs remain a global issue, as much of the developing world still report usage. Considering the lack of studies on OCP-induced endocrine disruption, TASLD, and other liver diseases, research like this highlights the need to understand the underlying mechanisms contributing to […]

(Beyond Pesticides, September 29, 2023) In unsurprising news, the Environmental Protection Agency (EPA) has reversed itself and decided not to ban a dangerous pesticide: tetrachlorovenphos (TCVP) used in pet flea collars and other flea products. This is despite its own earlier decision to ban TCVP in pet collars and scathing criticism of its methods and conclusions by the courts. First registered in 1966, TCVP belongs to the notoriously toxic organophosphate chemical family and is classified by the World Health Organization as “possibly carcinogenic to humans.” It was originally registered to Shell Chemical, then to E.I. duPont de Nemours, then to Hartz Mountain Corporation and Fermenta Animal Health Company.  Early on, it was registered for use on food crops and livestock, but the crop uses were voluntarily de-registered in 1987. It is still widely used on pets and farm animals. In 1995, EPA issued the opinion that “all uses of tetrachlorvinphos, with the exception of oral feed-through larvicide treatment to livestock intended for food use, will not cause unreasonable risk to humans or the environment.” Since then, the agency has contorted itself repeatedly to allow TCVP to remain on the market. There is little research available on TCVP’s human health effects; the […]

(Beyond Pesticides, September 28, 2023) As the United States commemorates the 50th anniversary of the Endangered Species Act (ESA), there is a growing recognition that the planet faces an existential biodiversity crisis, with a rising number of species on the brink of extinction. In a collective effort to address threats to global biodiversity (i.e. diversity of all life), a coalition of environmental organizations including Beyond Pesticides, are sending an urgent letter to President Joe Biden. This letter, titled “Meeting the Challenges of the Biodiversity and Extinction Crisis Over the Next 50 Years,” calls for bold and comprehensive action to preserve our planet’s natural heritage for future generations. The ESA is celebrated as one of the most effective conservation laws globally, credited with preventing the extinction of 99 percent of listed species. Over the past five decades, the ESA has played a pivotal role in preventing these extinctions by safeguarding the most critically endangered species within biological communities. However, this concentration on highly threatened species often results in temporary solutions that may not comprehensively address the broader issue of biodiversity loss. The ESA establishes a framework to categorize species as “endangered” or “threatened,” granting them specific protections. While it is crucial […]

(Beyond Pesticides, August 16, 2023) A study published in Environmental Science and Pollution Research further supports the indication that exposure to organophosphate insecticides (OPs) increases the risk of asthma among the U.S. general population. According to the Asthma and Allergy Foundation of America, “The burden of asthma in the United States falls disproportionately on people with low-income, senior adults, and Black, Hispanic and American Indian/Alaska Native people,” making these groups more susceptible to developing this chronic lung disease upon OP exposure.   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 body systems like the repository system. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal function. However, damage to the respiratory system can cause several issues—from asthma and bronchitis to oxidative stress that triggers the development of extra-respiratory manifestations like rheumatoid arthritis and cardiovascular disease. Therefore, the rise in respiratory illnesses and organophosphate […]

(Beyond Pesticides, April 14, 2023) In March, scientists at the National Marine Fisheries Service (NMFS) issued a draft Biological Opinion (BiOp) stating that carbaryl and methomyl — two commonly used carbamate insecticides — cause significant harm to dozens of already-endangered fish species in the Pacific Northwest’s Columbia, Willamette, and Snake rivers. The BiOp indicates that these toxic compounds, in wide use on orchards and field vegetables throughout the Willamette Valley, the Columbia River Gorge, and southeastern Washington, will likely threaten scores of species on the Endangered Species list: 37 species at risk from carbaryl and 30 from methomyl. In addition, the BiOp says, “both are likely to harm or destroy many areas designated as critical habitat for endangered species.” The mitigation measures proposed by NMFS and the U.S. Environmental Protection Agency (EPA), in light of this BiOp, are likely to be inadequate to the problem, given that both compounds can drift through air and/or migrate into groundwater and generate toxic runoff. These two neurotoxic insecticides, carbaryl and methomyl, are very toxic to bees, birds, fish, and other aquatic organisms. In addition, carbaryl is a likely human carcinogen and an endocrine disruptor, and has harmful impacts on multiple bodily systems. Methomyl is […]

(Beyond Pesticides, March 14, 2023) A study published in Environmental Research and Public Health finds occupational pesticide exposure increases the risk of sleep disorders among farmworkers and pesticide applicators. Specifically, many pesticides, like organophosphates (OPs), are detrimental to neurological function through inhibition of the enzyme acetylcholinesterase (AChE) responsible for ending a neurotransmission event after relaying the necessary information. Without an end to neurotransmission events, individuals experience a buildup of acetylcholine, resulting in convulsions, headaches, weakness, impacts on bodily senses, and other cognitive/mental changes. In addition to illnesses from chemical exposure, inadequate sleep has links to several chronic diseases like type 2 diabetes, cardiovascular disease, obesity, and depression. Therefore, given research links to sleep-related disorders and bodily functions, including endocrine, metabolic, neurological, and cognitive disorders, studies like this can help government and health officials identify how pesticides’ impact on the brain elevates health concerns. The study notes, “The study’s findings can be used to create strategies for addressing mental health issues and promoting mental health and quality of life.” Researchers assess the sleep patterns among individuals living in southeast Spain, near the coast of Almeria, where chemical-intensive agriculture from greenhouses is prevalent. Of the 380 participants in the study, 189 were […]

(Beyond Pesticides, March 9, 2023) A study published in Environmental Research finds exposure to organophosphate (OP) compounds during pregnancy, or prenatal OP exposure can cause shortfalls in language development abilities at 18 months, stifling preschool-age language expression. Additionally, a timely and co-occurring study published in Environmental International confirms similar results, highlighting that chlorpyrifos (an organophosphate) impedes neurological and psychological development, including language communication and all motor skills of offspring at 12 and 18 months old. 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 pesticides’ impact on the brain elevates health concerns. The Environmental Research authors note, “The etiology [cause] of language development is complex, and this work further highlights the importance of the prenatal environment as a mechanism of influence that are associated with deficits in early language acquisition and ability, which could signal increased behavioral problems and academic difficulties in later childhood that extend […]

(Beyond Pesticides, May 6, 2022) A December 2021 report commissioned by the trade group Salmon Scotland concludes that the use of pesticide products by the nation’s salmon farms represents potential risk to “wild” swimmers (those who swim in open ocean waters). The report’s primary finding is that the use of insecticide products containing azamethiphos (an organophosphate), deltamethrin, and hydrogen peroxide to control sea lice in farmed fish contaminates sea water and, thus, threatens swimmers in the areas around the farms. Beyond Pesticides has reported on pesticide use in aquaculture, and most recently, on developing resistance — in the parasitic lice (Lepeophtheirus salmonis) that endanger both wild and farmed fish populations in the North Atlantic — to some of the chemical treatments used by aquaculturists to combat the parasite. The intense exploitation of wild fish and other marine creatures for human food (and as an ingredient in animal feeds) has caused, in recent decades, depletion of fish and seafood stocks across the world. The aquaculture industry — in which various aquatic species (fish, shellfish, and some plants) are bred, raised, and harvested in the open ocean — has grown rapidly as a response. Since the 1960s, the farming of salmon in the […]

(Beyond Pesticides, February 10, 2022) A National Institute of Environmental Health Sciences (NIEHS)-funded study finds that patterns of pesticide exposure among farmers have geographical and temporal significance. Specific use of and exposure to organophosphate and carbamate chemicals decrease enzyme activity within the body, resulting in greater health anomalies among farmers, especially during agricultural seasons. The use of xenobiotic (foreign chemical compounds) substances like pesticides and fertilizers in agriculture are increasing. Thus, those working with and around these toxicants must have protection. Considering that agricultural workers often experience pesticide exposure at higher rates due to occupation, long-term research must identify potential health concerns surrounding common pesticides. The study author, Dana Barr, Ph.D., states, “The majority of farmers in this study reported that they had at least one health symptom associated with pesticide intoxication. This investigation can be used to promote safer use of pesticides among farmers and mitigate exposure among residents living near a rice field. The findings will be critical for establishing and launching several preventive programs in the future.” Researchers evaluated the health effects of pesticide exposure among a cohort of farmers in Thailand during inactive and active rice farming periods. Using geographic information system (GIS) mapping, researchers compared […]

(Beyond Pesticides, February 3, 2022) A study published in the journal Thorax finds lifetime occupational (work-related) exposure to pesticides increases incidents of chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis. Although research often attributes COPD risk to genetics or cigarette smoking, the increasing rate of COPD incidents indicates an external cause of disease development. Although an exact etiology (cause) of the increase in respiratory disease cases remains unknown, the connection between chronic respiratory diseases and exposure to pesticides continues to strengthen. Several circumstances, including smoking patterns, poverty, occupation, and diet, can influence disease prognosis. However, studies show that relative exposure to chemicals like pesticides can occur within each circumstance, making chemical exposure ubiquitous. Additionally, pesticide drift is an omnipresent issue impacting communities surrounding farming operations, and dust may harm humans, plants, and aquatic systems. Therefore, this review highlights the significance of evaluating the association between pesticide exposure and disease development, especially for diseases generally attributed to genetics or vices. Researchers in the study note, “[W]e found that cumulative exposure to pesticides is associated with an increased risk of COPD, with positive exposure-response trends. The unique large sample and the confirmation of our results in sensitivity analyses, in particular in never-smokers, support the validity […]

(Beyond Pesticides, September 30, 2021) Individuals working or living in areas with frequent neurotoxic pesticide use experience more amyotrophic lateral sclerosis (ALS) incidences than the general population. The study, published in NeuroToxicology, finds a positive association between sporadic (non-genetic, spontaneous) ALS incidences among individuals exposed to neurotoxic pesticides.  Amyotrophic lateral sclerosis (or Lou Gehrig’s disease) is a neurodegenerative disease that affects the nerves in the brain and spinal cord. As many as 16,000 – 20,000 Americans live with this condition, which weakens muscle/motor function leading to loss of muscle control for walking, talking, eating/swallowing, and breathing. Severe ALS progression is fatal and has no current cure. Although research supports genetic factors play a role in disease etiology (cause), most ALS cases do not result from genetic inheritance. Several research studies demonstrate exposure to environmental or work-related toxicants (i.e., pesticides) predispose humans to the disease. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. Therefore, research like this showcases the importance of assessing aggregate health risks associated with toxic chemical exposure, especially for illnesses, which are not curable. In this study, the researchers note, “[W]e identified pesticides applied to crops in the area of […]

(Beyond Pesticides, September 23, 2021) A study by Claremont Graduate University finds exposure to agricultural pesticides increases brain cancer risk up to 20 percent. This study expands on a 1998 study evaluating brain cancer risk among the farm population using epidemiologic studies. The etiology (cause) of brain cancer is inconclusive for many forms, including glioma and meningioma. Brain cancer risk factors include family history and exposure to radiation. However, geographical variance in brain cancer incidents suggests environmental pollutants like pesticides contribute to risk. Various research studies already note the adverse effects pesticide exposure has on the brain. These effects range from headaches and tumors to learning and developmental disabilities among children and adults. Although general cancer incidents are decreasing, brain and nervous system cancers are rising. Therefore, studies like this highlight the need to reevaluate pesticide exposure limits for those working with or around agricultural chemicals to prevent chronic, deadly diseases. The study researchers note, “This comprehensive review and meta-analysis encompassing 42 years of the epidemiologic literature and updating two previous meta-analyses by 20 years supports an association between farming and brain cancer incidence and mortality.[…]Our analyses suggest that the elevated risk has been consistent over time, and the addition of newer studies […]

(Beyond Pesticides, July 9, 2021) The investigative online publication The Intercept has turned its attention to the current and historical role of industry in distorting, undermining, and outright suppressing the protective function of the U.S. Environmental Protection Agency (EPA) with regard to pesticide exposures. The subsequent reporting — “The Department of Yes: How Pesticide Companies Corrupted the EPA and Poisoned America” — is a devastating chronicle of the theme and particulars that Beyond Pesticides has covered for years. That is, that EPA has repeatedly disregarded its charge to protect human and environmental health in favor of enabling industry to continue its chemical experimentation on the populace and on the nation’s multiple natural resources. This pattern must change if the agency is to enact its mission and the public is to be protected. The Intercept interviewed more than 24 people with expertise on the regulation of pesticides, including 14 who have worked in EPA’s Office of Pesticide Programs (OPP). The chief takeaway from those interviews, as written by reporter Sharon Lerner, is that EPA “is often unable to stand up to the intense pressures from powerful agrochemical companies, which spend tens of millions of dollars on lobbying each year and employ many […]

(Beyond Pesticides, May 13, 2021) Scientists are advocating for stricter pesticide bans to lower deaths from deliberate pesticide ingestion. The request for this toxic pesticide ban follows a University of South Australia study detailing discrepancies in World Health Organization (WHO) classifications of pesticide hazards that rely on animal rather than human data. Previous studies demonstrate an increased risk of developing depression, especially among agricultural workers and landscapers who use pesticides. Acute exposure to chemicals, including organophosphate and carbamate pesticides, tends to put farmers at greater risk of suicide than the general population. This research highlights the significance of assessing pesticide toxicity and health effects using human data rather than animals to understand health effects resulting from pesticide exposure. Society tends to rank mental health risks second to physical health. However, pesticide poisonings account for one in five suicides globally. Therefore, it is vital to address the accessibility and necessity of conventional pesticide use to safeguard human well-being, especially in countries lacking adequate chemical regulations. The study’s scientists note, “The human data for acute toxicity of pesticides should drive hazard classifications and regulation. We believe that a global benchmark for registration of pesticides should include a less than 5% case fatality after self-poisoning, which could prevent many […]

(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 […]
