Study of Biological Diversity Effects of Pesticide Mixtures Highlights Underestimated Risks to Ecosystems

Wednesday, September 17th, 2025

(Beyond Pesticides, September 17, 2025) A study in Environmental Science & Technology finds additive effects of a synthetic pyrethroid insecticide (cypermethrin) and two fungicides (azoxystrobin and prochloraz) on biological control, biomass of major invertebrate trophic groups (position in food web), and soil ecosystem processes in arable systems (land suitable for growing crops). The study authors further highlight the failure of pesticide regulations to consider elaborate trophic interactions and pesticide mixtures, as well as additive and synergistic effects within their assessments, calling attention to the complexity of real-world exposures and the lack of research to fully understand the implications of chemical use for agricultural and land management purposes. “Arable systems have a high dependence on diverse natural biota to support pest control, soil bioturbation, and nutrient recycling,” the researchers write. These communities rely on a balance of organisms within various trophic levels in order to function and provide vital ecosystem services. Disruptions caused by environmental contaminants, such as pesticides to nontarget organisms, impact entire ecosystems and overall biodiversity. As the authors state, current risk assessments underestimate the real-world risks of petrochemical pesticides and synthetic fertilizers that, despite a wide body of science connecting exposure to deleterious health and environmental effects, are […]

Review Links Pesticides and Contaminants to Mechanisms that Threaten Women’s Reproductive Health

Thursday, August 14th, 2025

(Beyond Pesticides, August 14, 2025) A review in Clinical and Experimental Obstetrics & Gynecology links various classes of environmental pollutants including pesticides and per- and polyfluoroalkyl substances (PFAS), both of which Beyond Pesticides has extensively covered, to adverse effects on the female reproductive system and common mechanisms of toxicity. These chemicals “disrupt the hypothalamic-pituitary-gonadal axis (HPG), impair ovarian function, and contribute to reproductive dysfunction through mechanisms such as oxidative stress, hormonal disruption, and epigenetic [gene expression or behavior] modifications,” the authors say. This leads to menstrual irregularities, infertility, and pregnancy complications, as well as increases in the risk of reproductive system disorders such as endometriosis, polycystic ovary syndrome (PCOS), and ovarian cancer, among others. “Additionally, transgenerational effects mediated by epigenetic modifications, germ cell damage, and placental transfer may adversely affect offspring health, increasing the risk of reproductive dysfunction, neurodevelopmental disorders, metabolic diseases, and cancer,” the researchers explain. This study, integrating recent epidemiological and experimental findings, provides an overview of major chemical classes that threaten women’s health and highlights the need for immediate action. As the authors point out, female reproductive health is important not only for those who choose to plan for a family but also for the overall well-being […]

Rheumatoid Arthritis Rates Elevated by Pesticide Exposure, Women Disproportionately Affected

Thursday, August 7th, 2025

(Beyond Pesticides, August 7, 2025) The novel study published in Arthritis & Rheumatology is the largest investigation of rheumatoid arthritis (RA) in women to date, finding evidence of heightened risks when exposed to insecticides through data collected from over 400 eligible women in the Agricultural Health Study (AHS). AHS participants include a cohort of thousands of licensed pesticide applicators and their spouses from Iowa and North Carolina, with this particular study as the first to consider the link between pesticide exposure and RA as it affects women’s health.   “Growing evidence suggests farming and agricultural pesticide use may be associated with rheumatoid arthritis (RA), but few studies have examined specific pesticides and RA among farm women, who may personally use pesticides or be indirectly exposed,” the study authors explain. The findings reveal that organochlorine insecticides that continue to persist in the environment, as well as organophosphate and synthetic pyrethroid pesticides used in public health or residential settings, correlate with RA diagnoses in women.  As shared in previous Daily News, for the most part organochlorine pesticides, including dichlorodiphenyltrichloroethane (DDT), are no longer used worldwide, but the legacy of their poisoning and contamination persists. These compounds are primarily made up of chlorine atoms, […]

Pesticide Contamination of Waterway Impairs Development of Freshwater Fish, a Keystone Species

Wednesday, August 6th, 2025

(Beyond Pesticides, August 6, 2025) A study published in Science of The Total Environment finds that “chronic pesticide exposure alters metabolism and impairs fish growth and health.” With increasing concern about the long-term consequences of pesticide persistence in ecosystems, the scientific literature continues to expand the body of research findings on adverse effects, including impacts on marine or aquatic ecosystems and organisms. Given the known and growing risks, there is an ongoing movement to move beyond petrochemical-based chemicals for agriculture and land management by adopting policies and programs that advance organic criteria and principles, as outlined in national organic law and practiced by tens of thousands of certified farmers and land managers across the country, and even more at the international level. Background and Methodology “The objective of this study was to assess the physiological responses of juvenile P. lineatus exposed to environmentally relevant pesticide mixtures by integrating multiple biological endpoints across sub-individual and organismal levels,” the authors write. The study was conducted at two sites in the Tibagi River watershed located in Paraná, a southern region in Brazil. There was a reference site (RFS) and an agricultural site (AGS), the former having minimal pesticide contamination and the latter having […]

Artificially Narrow EPA Definition of PFAS Mischaracterizes Widespread Threat to Health and Environment

Wednesday, July 30th, 2025

(Beyond Pesticides, July 30, 2025) The definition of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” due to their persistence, continues to be debated in regulatory agencies, with many scientists arguing that certain types of chemicals in this vast group are not accurately captured in risk assessments. A wide body of science on the adverse health and environmental effects of PFAS exists, as these synthetic chemicals have become ubiquitous in nature, wildlife, and humans, as demonstrated by biomonitoring studies. Recent research, documented in a literature review in Environmental Science & Technology and additional articles, highlights the importance of a universal, cohesive definition of PFAS that incorporates all fluorinated compounds, including the long carbon chain PFOA (perfluorooactanoic acid) and PFOS (perfluorooctanesulfonic acid) as well as the ultrashort-chain perfluoroalkyl acids (PFAAs). In order to protect health and the environment from the ever-increasing threat of both long and short chain PFAS’ adverse effects, including cancer, endocrine-disrupting effects, and immune system damage, a comprehensive definition of the compounds causing harm is critical to adequate protection and regulatory decisions. The multitude of sources of PFAS and various exposure routes leads to widespread contamination of the environment and organisms. PFAS in agriculture represents a […]

Behind the Numbers Linking Pesticides to Neurological Disorders, the World’s Largest Source of Disability

Tuesday, July 29th, 2025

(Beyond Pesticides, July 29, 2025) Are neurological diseases increasing around the world? Yes and no, according to a report published by The Lancet in 2024 on the global burden of nervous system diseases between 1990 and 2021. About 3 billion—a third of the world’s people—suffer from some nervous system condition. These diseases cause 11 million deaths and 443 million disability-adjusted life years (DALYs), which are a measure of the years lost to illness, disability, or early death. Neurological disorders are now the world’s largest source of disability. The Lancet report does not include an analysis of the role of pesticides in the burden of neurological disease worldwide, although environmental health research continues to expand the evidence that pesticide exposure is a major contributor to that burden. The Lancet report indicates that DALYs from Parkinson’s disease have increased by 10 percent, and autism spectrum disorder and dementia by 2 percent each. Multiple sclerosis has declined by 11 percent, according to the report. Importantly, most of the improvement has come from medical interventions, not prevention—in other words, people are living longer with the diseases rather than avoiding them altogether. But this is not true globally: The burden of disease, and particularly premature death, […]

As Millions Die from Antibiotic-Resistant Infections Annually, Study Shines Light on Pesticide Connection

Friday, July 11th, 2025

(Beyond Pesticides, July 11, 2025) Pesticides and antibiotics are linked inextricably in the looming crisis of human and ecosystem health. Both started out as quasi-miraculous solutions to age-old human problems, yet it has been clear that the failures of each present severe challenges—and that they are synergistic because they trigger the same kinds of defensive mechanisms in their targets: insects, fungi, and weeds on the one hand, and microbes on the other. A review of contamination of waterways in India with pesticides and antibiotics, published in Environmental and Geochemical Health, recounts the many threats that arise when these chemicals mix and how their presence in water makes the problems much worse.    Globally, about five million people died in 2019 from infections with antibiotic-resistant microbes. By 2050, according to a World Bank estimate, antibiotic resistance could add $1 trillion to global health care costs and subtract $3.4 trillion from annual global gross domestic product. While the world slowly realizes the urgent need to counter antibiotic resistance, the role of pesticides in generating it has received less political and public attention. But there is no doubt that pesticides are strongly implicated. In fact, the resistance of microbes to antibiotics is no […]

Tanzania at a Crossroads, Building an Organic Future after Decades of Toxic Pollution

Wednesday, July 9th, 2025

(Beyond Pesticides, July 9, 2025) Policymakers in Tanzania are calling for increased investments in organic agriculture for the 2025/26 fiscal year budget, demonstrating the increase in political will to advance new systems of farming and land management after decades of relying on Green Revolution-style, or chemical-intensive, policies. On June 20, various ministers representing the national government presented speeches to Parliament on the national government’s plan and budget recommendations, as well as highlighting the previous fiscal year’s trends and use of funds.   Political and popular support for organic agricultural systems has gained momentum across the globe. Worldwide, organic farming practices quadrupled from 2000 to 2018, with over 180 countries supporting a global transition to organic agriculture. Newly published global survey data by the Research Institute of Organic Agriculture (FiBL) and International Federation of Organic Agriculture Movements – Organics International (IFOAM) reveal global organic agriculture to be at an all-time high, with 71.5 million hectares of farmland in production as of 2020. (See Daily News here). Farmer and agricultural cooperatives around the world, from Brazil to Madagascar and Togo, leverage organic systems to develop competitive business models in regional, national, and international markets. (See Daily News here.) The European Union, with […]

U.S. Policy Allows Cancer-Causing Pesticide Use Even Though It Is Not Needed to Grow Food and Manage Land

Tuesday, June 24th, 2025

(Beyond Pesticides, June 24, 2025) As changes in the executive branch of the federal government upend expectations among environmental stakeholders, the regulation of food safety in the United States is being revealed as a rickety structure built over a century with unpredictable and sometimes contradictory additions, extensions, remodels, and tear-downs. In the short term, clarity is unavailable, but there have been calls for revision and strengthening of regulatory processes—requiring lawmaker and regulator willingness to incorporate the vast body of evidence that pesticides do far more harm than good, and that organic regenerative agriculture is the surest path to human and ecological health. News reports out of Costa Rica in May brought public attention to drafted legislation to ban pesticides in the country that the World Health Organization (WHO) has defined as “extremely or highly hazardous, or those with evidence of causing cancer, genetic mutations, or affecting reproduction, according to the Globally Harmonized System (GHS).” The headline sparked a relook in this Daily News at the current and historical failure of U.S. policy, which allows cancer-causing pesticides in food production and land management, despite the booming success of a cost-effective and productive, certified organic sector for which petrochemical pesticides are not […]

Report Stresses Findings of Pesticide Contamination of Largest U.S. Estuary Shared by Six States—Chesapeake Bay

Friday, June 13th, 2025

(Beyond Pesticides, June 13, 2025) A report highlights the ongoing stress to the Chesapeake Bay Watershed from pollutants, particularly pesticides. The Chesapeake Bay is the largest estuary in the contiguous United States, with tributaries shared among six states and the District of Columbia. It receives runoff from nine major river systems traversing a wide mix of land uses, with significant agricultural and urban areas nearest the Bay and forest along the western boundary. Nearly 13 million people get their drinking water from the watershed. The watershed report by the Maryland Pesticide Education Network focuses primarily on the herbicide atrazine, the neonicotinoid insecticide thiamethoxam, and per- and polyfluorinated compounds (PFAS). Atrazine needs little introduction, being notorious for disrupting hormones, particularly estrogen, as demonstrated by the pioneering work of Tyrone Hayes and more recent research analyzed by Beyond Pesticides here, here and here. In male fish, it can trigger production of egg proteins, especially vitellogenin, and development of eggs in their testicles. These are manifestations of intersex, in which an organism shows forms of sexual differentiation of both sexes. The Chesapeake watershed report notes that atrazine and metolachlor (also an estrogen/androgen disruptor and suspected human carcinogen) occur together frequently in the Chesapeake […]

Study Maps the Gut Microbiome and Adverse Impacts of Pesticide Residues

Wednesday, June 11th, 2025

(Beyond Pesticides, June 11, 2025) Researchers developed a novel tool* in a recent study published in Nature Communications this year that successfully creates a map of the “pesticide-gut microbiota-metabolite network,” identifying “significant alterations in gut bacteria metabolism.” While the study authors acknowledge that this is not a complete map, since they selected specific pesticides and bacterial partners, the research adds to the body of peer-reviewed scientific literature that underscores the relationship between pesticide residues and human gut health. Organic farmers, as well as any land steward invested in agroecological practices and soil health, understand that microbial life (both in the body and in the soil) is dangerously undermined by the status quo of chemical-intensive land management. Background and Methodology The researchers leverage mass spectrometry to test metabolite (metabolomics) and lipid (lipidomics) relationships with pesticide residues, as well as an in vivo mouse model. *The map itself is a form of computational biology, which advocates have warned could be a false solution if not accompanied by other proven scientific methods. See here for analysis by the Natural Resources Defense Council on risks of unproven methods such as New Approach Methodologies [NAMs]. All major phylogenetic (“evolutionary relationships among biological entities”) groups are […]

Dramatic Array of Pesticides Used Outdoors Make Their Way Inside, Contaminating the Indoor Environment

Tuesday, April 22nd, 2025

(Beyond Pesticides, April 22, 2025) While it has been widely found that farmworkers bear the brunt of agricultural pesticide exposures in fields and outbuildings, the outdoor use of chemicals contaminating living spaces is documented in an increasing number of studies. Two recent studies add to earlier findings that raise exposure and health concerns. A large European study of house dust contaminants, published in Science of the Total Environment, finds more than 1,200 anthropogenic compounds, including numerous organophosphates, the phthalate DEHP, PCBs, pharmaceuticals, and personal care products. And, a recent Argentine study, “Pesticide contamination in indoor home dust: A pilot study of non-occupational exposure in Argentina,” examines contaminant levels in household dust in villages and towns distributed throughout the Pampas region, where soybeans, corn, sunflowers, and livestock, especially cattle, are raised. The study participants were not agricultural workers, but teachers, government workers, librarians, retirees, college students, doctors, lawyers, artists, and business people. The Argentine study reinforces what has been previously reported, which emphasizes findings that there is no doubt that pesticide residues accumulate in homes adjacent to agricultural fields and pastures. For example, in 2023, Beyond Pesticides reported on a study of 598 California homes near agricultural areas sampled for carpet […]

Pesticides Found in Marine Atmosphere Over Deep Atlantic Ocean, Documented for the First Time

Wednesday, April 16th, 2025

(Beyond Pesticides, April 16, 2025) Documented for the first time, 15 currently used pesticides (CUPs) and four metabolites (breakdown or transformation products—TP) were found in the marine atmosphere over the Atlantic Ocean. Three legacy (banned) pesticides were also discovered. According to a recent study published in Environmental Pollution, researchers found empirical evidence for pesticide drift over remarkably long distances to remote environments. The findings of this study build on existing research that pollution knows no borders or boundaries, emphasizing Beyond Pesticides’ mission to advocate for the value of the precautionary principle through the elimination of synthetic chemicals and replacement with organic systems that address the root causes of pest pressures–including systemic failure to feed soil microbial life.   Background and Methodology “In this study, 329 pesticides, including 282 CUPs and 36 transformation products, were [sampled for] in the atmosphere across a south-north transect on the Atlantic Ocean,” said the authors. They unpack the three main objectives to address the focus and major objectives of their research: “[T]he determination of pesticide concentrations in the atmosphere of the Atlantic Ocean, The investigation of the spatial distribution of pesticides across the Atlantic Ocean, and The elucidation of potential sources and factors influencing pesticide transport […]

In Honor of a Living Legend, LA County Declares April 10 as Dolores Huerta Day

Thursday, April 10th, 2025

(Beyond Pesticides, April 10, 2025) The Los Angeles Board of Supervisors has voted to declare today, April 10, Dolores Huerta Day, honoring the lifelong efforts of social justice activist Dolores Clara Fernández Huerta on the celebration of her 95th birthday. In the words of Chair Pro Tem Hilda L. Solis, according to Colorado Boulevard, “Dolores Huerta’s contributions to Los Angeles County and to Latinos across the country have inspired generations of leaders fighting for justice for all. Now more than ever, we honor Dolores Huerta for her work as one of the most influential labor activists of our time… may her legacy continue to light a fire in us all.”  Ms. Huerta, in accepting the recognition, noted, “I accept this on behalf of Los Angeles’ working people, especially our immigrant community, whose labor supports families and children. The Supervisors have gone above and beyond to assist immigrants, and as we face challenges ahead, it’s vital to continue supporting their bold, compassionate leadership for our most underserved communities.”  This action follows prior recognition from then Acting Governor of California Eleni Kounalakis in 2024 and the state of Washington in recognizing Ms. Huerta’s decades of leadership. It comes in the wake of […]

Literature Review of Over 200 Studies Highlights Pesticide Threats to Women’s Reproductive Health

Tuesday, April 8th, 2025

(Beyond Pesticides, April 8, 2025) A comprehensive literature review in Environment & Health analyzes evidence from human biomonitoring, epidemiological studies, and toxicological studies that link adverse effects on women’s reproductive health, specifically impacting the ovary, to pesticide exposure. In examining the scientific literature, consisting of over 200 studies performed in the last 25 years, the authors find pesticide exposure threatens women’s health through ovarian dysfunction. “Epidemiological studies have shown that pesticide exposures are associated with early/delayed menarche [first occurrence of menstruation], menstrual cycle disorders, early menopause, long time to pregnancy, polycystic ovary syndrome, primary ovarian insufficiency, infertility, and implantation failure in women,” the researchers state. They continue, “Both in vivo [in animals] and in vitro [in cells] studies have shown that exposure to pesticides disrupts the estrous cycle, reduces the follicle pool, alters hormone levels, and impairs oocyte [egg] maturation.” These reproductive implications are noted with many different classes of pesticides, such as insecticides, including organochlorine pesticides (OCPs), organophosphates (OPs), pyrethroids, and neonicotinoids, as well as herbicides and fungicides. The authors, however, comment on present research gaps: “Much of the available epidemiological evidence focuses on legacy insecticides, such as OCPs, and a subset of insecticides that are still in use […]

Catastrophic Harm to Women from Pesticides Drives Call for Their Elimination

Monday, March 10th, 2025

(Beyond Pesticides, March 10, 2025) Following International Women’s Day, celebrated on March 8, 2025, the poignant findings on women, gender, and hazardous substances in a United Nations report raise critical issues of concern and cause for urgent action to phase out petrochemicals. The Report of the Special Rapporteur on the implications for human rights of the environmentally sound management and disposal of hazardous substances and wastes, by Marcos Orellana, was delivered to the 79th Session of the United Nations General Assembly in July 2024. Excerpts from the report follow: “Women make up roughly 60 to 70 per cent of the agricultural labour force in developing countries where pesticides and pesticide handling are especially poorly regulated. In Zambia, for example, two thirds of the labour force is engaged in agriculture, and 78 per cent are women farmers and peasants. Women there play a significant role in pesticide application, often without any or adequate personal protective equipment, especially during activities such as weeding, harvesting, and washing pesticide-laden clothes.” “In higher-income countries, women who do agricultural work are often poor and/or migrants; pesticides are one of many dimensions of marginalization and damage to their well-being. The European agriculture sector uses many seasonal and […]

Trump Administration’s Dismantling of Federal Environmental and Public Health Programs Shifts Focus to States

Monday, February 24th, 2025

(Beyond Pesticides, February 24, 2025) The sweeping firing of federal workers, including an estimated 200,000 probationary employees (under one to two years of employment), will have a broad impact on programs to protect health and safety as well as the environment, leaving a critical need for local and state government to fill some of the gaps in critical programs, where possible. A headline in Science magazine warns, “Mass firings decimate U.S. science agencies,” and the dean of the College of Agricultural Sciences at Oregon State University told Oregon Public Broadcasting, “We’ve lost half of our teams, and all of these up-and-coming young scientists. . .so it’s like we’ve lost the next generation of scientists in agriculture and natural resources.” The same applies to important positions across the federal government, affecting every aspect of work necessary to protect public health and biodiversity and address the climate crisis. In response to President Trump’s executive orders and actions, there has been, as The New York Times reports, “new lawsuits and fresh rulings emerging day and night,” raising what experts fear may become a constitutional crisis. With the upheaval in the federal government, attention turns to the importance of state and local policies and […]

Neonic Insecticide Impairs/Kills Beetle Listed as Threatened and Important to Ecosystem Health, But Not Protected

Wednesday, February 5th, 2025

(Beyond Pesticides, February 5, 2025) A study in PLOS One finds acute and chronic impacts of nontarget toxicity on the American burying beetle, Nicrophorus americanus, with neonicotinoid insecticide exposure. In assessing environmentally relevant concentrations of the neonicotinoid insecticide imidacloprid with N. americanus, the researchers note both mortality and behavioral effects that leave the species at high risk of predation. These effects mean the American burying beetle “may be at greater risk to insecticide exposure than previously thought and vulnerable to episodic, low-dose neonicotinoid exposure,” the authors say. This data sheds important light on a species that has been listed by the U.S. Fish and Wildlife Service (USFWS) as threatened. Burying beetles provide important ecosystem services within the environment such as “burying carrion, increasing available nutrients in soil, and expediting carrion decomposition, while acting as a food source for secondary consumers,” the researchers state. (See more on ecosystem services and beneficial insects here, here, and here.) The N. americanus species are habitat generalists and can be found in grasslands, wet meadows, and forested areas that neighbor agricultural lands and introduce the beetles to pesticide drift and soil residues. While acute and chronic effects vary in duration and severity, pesticide exposure resulting […]

Sleep Disorders in Farmers and Farmworkers Linked to Pesticide Exposure in Study Supporting Similar Findings

Friday, January 31st, 2025

(Beyond Pesticides, January 31, 2025) A recent cross-sectional study in Heliyon highlights the link between sleep disorders in Thai farmers and pesticide exposure. The authors find pesticide exposure as an important risk factor for sleep disorders after surveying 27,334 farmers over the age of 20 who had work experience for at least five years. The importance of sleep health is reflected both physically and mentally, as studies find “sleep deficiency increase[s] mortality and various health complications, including hypertension, obesity and type 2 diabetes, cardiovascular diseases, mood disorders, and neurodegenerative disorder.” Additional studies find that these issues are compounded when sleep health is affected by environmental factors such as pesticide exposure. (See previous Beyond Pesticides’ coverage here and here.) The researchers report: “The study found a positive association of 19 individual pesticides (twelve insecticides, two herbicides, and five fungicides). Some associations demonstrated a dose-response pattern. Additionally, the study revealed that women are at a higher risk of sleep-related issues with pesticide exposure compared to males. These results not only substantiate existing literature but also unveil several new individual pesticides that may impact sleep health.” Focusing on study participants in Thailand, which is “characterized by heavy pesticide use and minimal protective measures, […]

Multitude of Studies Find Epigenetic Effects from PFAS and Other Endocrine Disrupting Pesticides

Thursday, January 16th, 2025

(Beyond Pesticides, January 16, 2025) In Ecotoxicology and Environmental Safety, researchers highlight a multitude of studies on endocrine disrupting chemicals (EDCs) and endocrine disrupting pesticides (EDPs) showing epigenetic effects from exposure. These EDCs imitate the action of endocrine hormones and lead to gene damage and multigenerational adverse effects to health. “These chemicals can interfere with the normal functioning of target tissues by altering their response to hormonal signals, thereby affecting various physiological processes including reproduction, development, the nervous system, the immune system, and even the process of carcinogenesis [causing cancer],” according to the authors from Hebei Agricultural University and Chinese Academy of Agricultural Sciences.   In causing epigenetic modifications, the authors describe that EDCs can create changes “at the nuclear and mitochondrial DNA (nDNA and mtDNA) or RNA levels, without changing the underlying DNA sequence. These alterations modify the structure or conformation of DNA, influencing gene expression and, consequently, cellular function.” They continue, “The mechanisms of epigenetics include changes in DNA methylation, chromatin modifications and the involvement of certain noncoding RNAs.” In reviewing over 80 studies on EDCs, predominantly fluorinated compounds such as per- and polyfluoroalkyl substances (PFAS), the researchers provide a summary of linkages between pesticide exposure and the […]

Multiple Studies Link Adverse Effects on Female Reproductive Health with Endocrine Disrupting Chemical Exposure

Thursday, January 9th, 2025

(Beyond Pesticides, January 9, 2025) In a Frontiers in Public Health review article, researchers report on the wide body of science connecting adverse effects to female reproductive system, such as infertility, with exposure to endocrine-disrupting chemicals (EDCs). The authors call these effects a significant concern for public health, as there has been growing evidence of EDCs with risk factors for decreased fertility.   Infertility “affects a substantial proportion of the world’s population with approximately one in six people affected,” the researchers note. They continue: “Over the last 70 years, global fertility has been constantly in decline due to behavioral and societal changes… [E]merging evidence has shown that infertility incidence is linked to exposure to environmental factors such as tobacco, alcohol, and a wide range of endocrine-disrupting chemicals (EDCs) including pesticides (chlorpyrifos, glyphosate, dichlorodiphenyltrichloroethane [DDT] and methoxychlor), phthalates, polychlorinated biphenyls (PCB), dioxins, and bisphenols.”  In this review, over 100 studies are summarized to showcase the link between EDC exposure and reproductive effects in women, including infertility and related diseases such as endometriosis, premature ovarian insufficiency (POI), and endocrine axis dysregulation. The studies included investigating the “mechanisms by which EDCs cause ovarian aging, folliculogenesis, decrease of oocyte quality, ovulation disorders, development and receptivity […]

Deadly Poisoning of Dozens of Children in South Africa Highlights Global Pesticide Threat to Human Life  

Thursday, December 19th, 2024

(Beyond Pesticides, December 19, 2024) As The New York Times reported last month, the government in South Africa declared a national emergency—23 children died and nearly 900 people were sickened from pesticide poisoning in Johannesburg’s Soweto township. The illnesses and fatalities have been traced to small amounts of highly neurotoxic pesticides, including the insecticides terbufos and aldicarb, found in local food items. These chemicals, described by South African President Cyril Ramaphosa as “street pesticides,” are being increasingly used (legally and illegally) for pest infestations in the townships and informal settlements of South Africa’s poorest communities, where poverty and inadequate waste collection exacerbates the pest management challenges.
