Environmental Toxicants, including Pesticides, Linked to Parkinson’s Disease - Beyond Pesticides Daily News Blog A review in Lancet Neurology provides a clear snapshot of the state of scientific understanding of Parkinson’s disease and how medicine and policy could be improved by shifting focus to the primary causes of the disease, namely environmental toxicants, and to emphasize prevention rather than devoting resources only to treatments and a cure.

Environmental Pesticide Exposure Alters Gut Microbes, Increasing Urgency for Organic Transition - Beyond Pesticides Daily News Blog (Beyond Pesticides, May 12, 2022) A report published in Environmental Health finds that exposure to environmentally relevant concentrations of pesticides can alter gut microbial communities, as demonstrated through fecal samples. Over 300 environmental contaminants and their byproducts, including pesticides, are chemicals commonly present in human blood and urine samples. Ample evidence demonstrates that environmental contaminants, including pesticides, negatively affect the human mouth and gut microbes. However, fecal samples provide an accurate representation of the microbial community existing in the gut. These toxicants can alter hormone metabolism, which adversely affects health outcomes. Adverse health effects of environmental contaminants include reproductive and developmental defects, diabetes, cardiovascular disease, liver disease, obesity, thyroid disorders, and improper immune operation. Although studies show how chemical exposures affect human health, more research is now questioning how these toxic chemicals influence gut health. Therefore, studies like these highlight the importance of evaluating how chemical contaminants deregulate normal bodily function through microbiome changes. The report notes, “Our results highlight the need for future dietary intervention studies to understand effects of pesticide exposure on the gut microbiome and possible health consequences.” Researchers examined dietary exposure to 186 common pesticide residues in the fecal excrement to determine impacts on the microbiome among 65 twins in the United Kingdom.

California to List Atrazine and Other Triazine Weedkillers to Prop 65 as Reproductive Toxicants - Beyond Pesticides Daily News Blog (Beyond Pesticides, July 13, 2016) California’s Office of Environmental Health Hazard Assessment (OEHHA) has announced that atrazine, its chemical cousins,  propazine,  simazine,  and its break down triazine compounds des-ethyl atrazine (DEA),  des-isopropyl atrazine (DIA)  and  2,4-diamino-6-chloro-s-triazine (DACT)  would be added to the list of chemicals known to the state to cause reproductive toxicity for purposes of the state’s Proposition 65. The formal listing has been delayed and will not be effective until July 15, 2016 due to litigation from the manufacturer, Syngenta, which opposes the listing. In 2014 the state announced its Notice of Intent to list the triazines: atrazine, propazine, simazine and their breakdown products under Proposition 65 — the state’s law on toxic chemicals. The listing of these chemicals was initially to be effective on August 3, 2015. However, Syngenta, manufacturer of atrazine, challenged the listing decision, leading to a delay in the formal decision. Syngenta Crop Protection v OEHHA  (Sacramento Superior Court case#34-2014-800001868). Syngenta’s challenge was unsuccessful and now the official listing can move forward, in spite of Syngenta’s pending appeal. The six chemicals will now be known as reproductive toxicants in the state of California effective July 15, 2016. See listing notice. http://oehha.ca.gov/media/downloads/crnr/listingnoticetriazines070516.pdf Proposition 65, officially […]
