(Beyond Pesticides, August 20, 2024) A study published online in the journal Environmental Toxicology and Pharmacology raises continuing concern about residual exposure to organochlorine pesticides (OCPs) and the disruption that they and their metabolites and isomers cause to biological systems. For the most part, OCPs, including dichlorodiphenyltrichloroethane (DDT), are no longer used worldwide, but the legacy of their poisoning and contamination persists. A 2022 article in Environmental Science & Technology cites California condors and marine mammals along California’s coast contaminated with several dozen different halogenated organic compounds (hazardous, often-chlorinated chemicals) related to DDT, chlordane, and other now-banned legacy chemicals. Other research finds DDT in deep ocean sediment and biota. And, more research finds multigeneration effects from DDT exposure with grandmothers’ exposure to DDT increasing granddaughters’ breast cancer and cardiometabolic disorder risk. This study may be the first compilation of research regarding the modes of action for distinct types of organochlorine pesticides (OCPs). The findings raise the significant danger of legacy chemicals that persist for generations and call for a precautionary regulatory standard that is focused on preventing harm and advancing alternative nontoxic practices and products. In tracking the ongoing scientific literature on a broad spectrum of adverse effects daily, Beyond Pesticides […]

(Beyond Pesticides, April 17, 2024) With headlines drawing public attention to the contamination of drinking water after years of federal government neglect, the U.S. Environmental Protection Agency (EPA) announced on April 10 new standards to reduce public exposure to PFAS, or per- and polyfluoroalkyl substances, commonly referred to as “forever chemicals” because of their persistence. EPA has finalized a National Primary Drinking Water Regulation (NPDWR) for six PFAS, including PFOA and PFOS, which EPA has recognized have no safe level of exposure, regulating new chemicals for the first time since the 1996 amendments to the Safe Drinking Water Act (SDWA). PFAS persistence and bioaccumulation in humans, wildlife, and the environment is due to the strength of a resulting fluorine–carbon atom bond. PFAS contamination of drinking water, surface and groundwater, waterways, soils, and the food supply—among other resources—is ubiquitous worldwide. PFAS is used in everyday products, including cookware, clothes, carpets, as an anti-sticking and anti-stain agent, in plastics, machinery, and as a pesticide. The action was welcomed by environmentalists and public health advocates as an important step but left many concerned that any level of exposure to these chemicals is unacceptable and critical of EPA’s ongoing failure to act despite years […]

With the elevated adverse impacts associated with pesticides and reproductive health, the Pregnant Workers Fairness Act (PWFA) law may be used to improve protections for farmworkers and other high-risk employees.

(Beyond Pesticides, January 5, 2022) Household pesticide use is associated with harmful impacts to infant motor development, according to a study published late last year in the journal Paediatric and Perinatal Epidemiology. The research focused on primarily low-income Hispanic women located in Los Angeles, California, enrolled in an ongoing study referred to as Maternal and Developmental Risks from Environmental and Social Stressors (MADRES). As with other pollutants in society, low-income, people of color communities are disproportionately in contact with toxic pesticides, resulting in exposures that can start early, and affect health over the course of one’s lifetime. Women enrolled in the MADRES cohort are over the age of 18, and speak English or Spanish fluently. For the present study, roughly 300 MADRES participants met the criteria for enrollment, and completed household pesticide use questionnaires at a 3-month post-natal visit. The questionnaire generally inquired whether pesticides had been used in one’s home since their child was born. After another 3 months, researchers also tested infants’ motor development using an Ages and Stages-3 protocol screening tool, which evaluates a child’s ability to execute muscle movements. Overall, roughly 22% of mothers reported pesticide use in their home during the first months of their […]
