(Beyond Pesticides, October 29, 2025) A study published in Environment International evaluates residues of individual and mixtures of endocrine-disrupting chemicals (EDCs), including pesticides, and finds an association between exposure and hyperactive behavior in children. The researchers evaluated urine samples from over 800 preschoolers, identifying and statistically analyzing concentrations of 22 EDCs, and finding that nine of these chemicals are significantly associated with hyperactivity trajectories and EDC mixtures are positively associated with hyperactive behavior, noting the strongest association in girls. “The current study indicates the adverse health effects of exposure to mixtures of EDCs among preschoolers, and suggests gender specificity in these effects,” the researchers state. They continue, “This highlights the importance of focusing on multi-pollutant exposure in early childhood.” Study Importance “Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children, which has become one of the main factors leading to the burden of disease in children and adolescents worldwide.” The authors continue: “Its core symptoms are high levels of inattention and/or hyperactivity/impulsivity during the preschool period. A meta-analysis showed that the overall prevalence of ADHD in children in China over the past 15 years was as high as 6.2%, and has been increasing over recent years.” In comparison, according […]

(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 […]

(Beyond Pesticides, November 4, 2024) The U.S. Environmental Protection Agency (EPA) last week opened a public comment period on the regulation of endocrine-disrupting pesticides, a proposal that lays out a drawn-out 10-year process that is narrow in evaluating the underlying mechanism that causes endocrine disruption. The proposal, published in the Federal Register as a partial settlement agreement and consent decree, responds to a lawsuit filed by farmworker and health groups challenging the agency’s failure to test and regulate endocrine-disrupting pesticides. Earlier in the year, after over 25 years of delay following the 1996 Congressional mandate to determine whether pesticides disrupt the endocrine system of humans and other organisms, EPA issued a proposal for modifying its approach to the implementation of the Endocrine Disruptor Screening Program (EDSP). The National Institutes of Environmental Health Sciences explains endocrine disruptors this way: “Endocrine-disrupting chemicals (EDCs) are natural or human-made chemicals that may mimic, block, or interfere with the body’s hormones, which are part of the endocrine system. These chemicals are associated with a wide array of health issues. . . Endocrine glands, distributed throughout the body, produce the hormones that act as signaling molecules after release into the circulatory system. The human body is […]

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