(Beyond Pesticide, December 20, 2022) A meta-analysis published in Chemosphere finds prenatal pesticide exposure, or pesticide exposure during pregnancy has a positive association with autism spectrum disorder (ASD) and attention deficit/hyperactive disorder (ADHD). Particularly, exposure to chemical classes organophosphate (OP) and pyrethroid (PYR) insecticides, in addition to the mother’s age during pregnancy (≥30 years old), increased the risk factor of ASD. ADHD risk increases among offspring whose mothers encounter organochlorine pesticides (OCPs) during gestation. The etiology or cause of ASD and ADHD involves the interaction of multiple components, including lifestyle and genetics. However, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, solvents, dietary residues, etc.) play a role in disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues resulting in chronic health effects. ADHD is estimated to affect 8-12% of school-age children worldwide. While it is a complex disease, and genetics may play a role, no specific genes have been identified, and there is increasing evidence that environmental factors like pesticide exposure facilitate the development of the condition. Additionally, U.S. Centers for Disease Control and Prevention (CDC) estimates that 1 in 54 children have been diagnosed with an autism spectrum […]

(Beyond Pesticides, October 19, 2022) Pet flea collars containing the insecticide tetrachlorvinphos (TCVP) are set to be banned by the U.S. Environmental Protection Agency, according to the agency’s long overdue response to a petition from the Natural Resources Defense Council (NRDC). The highly toxic pesticide has not been used on crops since 1987, yet was permitted for decades in flea collars where children could be intimately exposed to the chemical while petting and playing with the family pet. The decade-long process of bringing use of these products to an end exposes the failures of the U.S. pesticide regulatory system, and how EPA’s weak and flawed decisions that infect the marketplace with severe consequences. One may ask: How many veterinarians prescribed these dangerous flea collars to pet owners, assuming that EPA has properly assessed exposure risks to their human owners? Advocates concerned about EPA’s ongoing propensity to defer to the pesticide industry are urging an overhaul of the regulatory process and a reorientation toward toxic pesticide elimination and the adoption of organic in order to address serious health and environmental threats. NRDC originally filed its petition to ban all uses of TCVP in 2009. The petition noted that the agency completely […]

(Beyond Pesticides, February 13, 2020) Congress unanimously passed the Food Quality Protection Act (FQPA) in 1996 to increase protections for children from pesticide exposure. Unfortunately, according to a new study published in Environmental Health, the law is not being employed by the Environmental Protection Agency (EPA) to its full capacity. For most of the 59 pesticides reviewed by the study, EPA did not apply an additional FQPA safety factor and thereby missed an opportunity to protect children’s health. In fact, FQPA solidified EPA’s reliance on risk assessment calculations and mitigation measures that consistently fall short of adequate levels of protection because of serious data gaps, a failure to consider exposure to mixtures and synergistic effects, and a bias against consideration of alternatives (alternatives assessment) that show toxic pesticides to be unnecessary. FQPA establishes a safety standard applied to all food commodities that considers specific risks for infants and children. The law requires EPA to assess the “aggregate risk” (considering exposure from multiple sources) and “cumulative exposure” to pesticides that have a “common mechanism of toxicity.” FQPA mandates “an additional tenfold margin of safety for the pesticide chemical residue and other sources of exposure shall be applied for infants and children […]
