(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 […]

(Beyond Pesticides, March 2, 2023) Populations experiencing higher levels of environmental pollutant exposure, specifically pesticides, also experience a higher rate of irritable bowel syndrome (IBS), according to a study published in Environmental Toxicology and Pharmacology. IBS is a gastrointestinal disorder that causes abdominal pain or discomfort and changes in bowel behaviors. IBS affects 25 to 45 million individuals in the U.S., mostly female (two-thirds). Additionally, a quarter to half of all gastrointestinal-related visits are for IBS symptoms. Despite the unknown etiology of IBS, ample evidence demonstrates environmental contaminants, like pesticides, negatively affect the gut microbiota, causing a microorganism imbalance and resulting in inflammation associated with IBS. The gut, also known as the “second brain,” shares similar structural and chemical parallels to the brain. The microbiota in the gut plays a crucial role in lifelong digestion, immune and central nervous system regulation, as well as other bodily functions. Although studies show how chemical exposures affect overall human health, a growing body of peer-reviewed scientific literature is now questioning how these toxic chemicals influence gut health and the subsequent occurrence of diseases. The study notes, “These findings may help to understand the relationship between pesticide exposure and IBS; however, more epidemiological and experimental research is needed to understand […]

(Beyond Pesticides, October 26, 2022) Inflammatory bowel disease (IBD) may be exacerbated by exposure to the herbicide propyzamide, used in both agriculture and on ornamental lawns and landscapes, according to research published in the journal Nature this month. As the rate of autoimmune diseases continues to increase rapidly in the U.S. and the world, it is critical for scientists to better understand the etiology behind these diseases and the environmental factors contributing to their development. Recent data show that the number of people living with Crohn’s disease and ulcerative colitis, common types of IBD, have risen annually by 3.4% and 2.8% respectively, between just the years 2001 to 2018. “As we learn more about the environmental factors that might contribute to disease, we can develop state- and national-level strategies to limit exposures,” said study coauthor Francisco Quintana, PhD. “Some chemicals don’t seem to be toxic when tested under basic conditions, but we do not yet know about the effect of chronic, low-level exposures over decades, or early-on in development.” Researchers did not begin their study investigating propyzamide. Initial intent focused on better understanding environmental factors that may be contributing to IBD. Using a range of different models, scientists cross-referenced data […]
