(Beyond Pesticides, August 8, 2025) In a study published in Environmental Pollution, researchers have detected eighty pesticides (35 insecticides, 29 fungicides, and 11 herbicides, and metabolites) in the ambient air of a rural region of Spain (Valencia) between 2007 and 2024. Despite these dramatic findings, the authors conclude that there is “no [observable] cancer risk,” “no inhalation risk for adults,” and only one pesticide concentration (the insecticide chlorpyrifos) showing “a potential risk to toddlers.” However, the authors did not conduct an aggregate risk assessment that would typically consider all routes of exposure to the individual pesticides detected, including through water, food, and landscapes. Not considered by the authors are the potential effects of pesticide mixtures and full pesticide product formulations (with all potentially toxic ingredients), also a deficiency in the U.S. Environmental Protection Agency (EPA) registration of pesticides under federal law. Of concern, as well, are other contaminants in pesticide products, including but not limited to per- and polyfluoroalkyl substances (PFAS), heavy metals, plastics (including microplastics), which contribute to chronic diseases and health risks, and adverse effects to ecosystem stability exacerbated by the climate crisis. Background and Methodology “This work aims to conduct a further study on the situation of […]

(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 […]
