(Beyond Pesticides, August 22, 2024) A screening and analysis of 36 pesticides finds traces of these chemicals in patients with “unexplained chronic kidney disease” from agricultural communities in the Indian province of Uttar Pradesh. Researchers conducting this study, published in the Journal of Toxicology and Environmental Health Sciences, identify organophosphates, organochlorines, and pyrethroids as the main culprits, building on years of existing research pointing to adverse health impacts originating from bioaccumulation of pesticides after acute and chronic exposure. Chronic kidney disease (CKD) is a condition that afflicts one in ten adults internationally, based on a peer-reviewed analysis from The Lancet. The Centers for Disease Control and Prevention (CDC) estimate that one in seven U.S. adults (or roughly 35.5 million people) have CKD, with as many as nine in ten adults with the disease undiagnosed, based on 2023 data. The correlation between high rates of CKD and multigenerational use of and reliance on pesticides for food production, lawn care, and general land management reinforces the calls of advocates, farmers, and health professionals to adopt a new approach rooted in organic principles. Methodology This study was conducted by a group of researchers from the Department of Chemistry at Babu Banarasi Das University […]

(Beyond Pesticides, June 21, 2024) A recent review of the scientific literature, published in Science of The Total Environment, analyzes multiple species of bees on a molecular level to better understand the poisoning mechanisms that could, as the authors see it, inform chemical risk assessments with more precision. The mechanisms “implicated in the tolerance of bees to specific pesticides, and thus as determinants of insecticide sensitivity, … include metabolic detoxification, insecticide target proteins, the insect cuticle and bee gut microbiota,” the authors write. This review references more than 90 studies performed over the last 30+ years, with most being published in the last 5-10 years, as the understanding and importance of molecular determinants of bee sensitivity has emerged. Pollinators, such as bees, provide crucial ecosystem services by pollinating both wild plants and essential crops. The exposure these insects are subjected to threatens their existence, which occurs through pesticide contamination that can lead to impacts on growth and development or even colony collapse.   “While bees have only been exposed to human-made pesticides over the recent past (last 80 years) they have co-evolved with plants and fungi which produce a range of xenobiotics, including plant allelochemicals and mycotoxins,” the authors state.

(Beyond Pesticides, May 17, 2024) Massachusetts Governor Maura Healey (D) proclaimed May 12 -18, 2024 as Multiple Chemical Sensitivity Awareness Week, first established in 1998 in numerous states across the U.S. Multiple Chemical Sensitivity (MCS)—also called chemical intolerance or Toxicant-Induced Loss of Tolerance (TILT), is characterized by disorders in one or more body systems, including respiratory, gastrointestinal, musculoskeletal, and neurological processes. It is thought to be caused by adverse reactions to environmental chemicals and/or biological substances such as mold. Affected individuals suffer fatigue, rashes, muscle and joint pains, memory loss, and other symptoms. The Massachusetts proclamation encourages “residents of the commonwealth to take cognizance” of the event and recognize the distress of their fellow citizens who suffer from MCS. May 12 is also known as International May 12th Awareness Day, an observance started in 2006 in the United Kingdom to educate the public about many diseases associated with sensitivity to chemicals, including MCS, fibromyalgia, and Gulf War Syndrome. While some scientists have considered MCS a psychological or psychosomatic problem, there is increasing support for the reality of MCS as a physical disease distinct from mental or emotional disorders. Yet there are no medical tests that can reliably confirm a diagnosis, […]

(Beyond Pesticides, April 5, 2024) Exposure to chemical toxicants, molds, and algae contributes to autism and attention disorders in children, according to research that bolsters earlier findings. The exposures may be most relevant, not in the children, but one generation back—in the parents. The study, “Assessing Chemical Intolerance in Parents Predicts the Risk of Autism and ADHD in Their Children,” was published in the March issue of the Journal of Xenobiotics. Led by Claudia S. Miller, MD, an immunologist at the University of Texas at San Antonio noted for her work on chemical intolerance (CI), the authors build on previous work published in 2015 establishing parental CI as a risk factor for autism and ADHD. Dr. Miller participated in Beyond Pesticides’ 2022 Forum Series. Recordings of her presentation are available on YouTube here and here. In 1996, Dr. Miller concluded that CI is induced by Toxicant-Induced Loss of Tolerance (TILT). For further details, see Beyond Pesticides’ Daily News Blog. Three years later Dr. Miller developed the Quick Environmental Exposure and Sensitivity Inventory (QEESI), a questionnaire for individuals tracing their toxicant exposures and symptom histories. QEESI was first developed with groups exposed to organophosphate pesticides, volatile organic compounds in reconstruction and […]

(Beyond Pesticides, March 21, 2024) Alarming levels of a hazardous pesticide plant growth regulator linked to reproductive and developmental effects, chlormequat, is found in 90% of urine samples in people tested, raising concerns about exposure to a chemical that has never been registered for food use in the U.S. but whose residues are permitted on imported food. Published in the Journal of Exposure Science and Environmental Epidemiology in February 2024 and led by Environmental Working Group toxicologist Alexis Temkin, PhD, a pilot study finds widespread chlormequat exposure to a sampling of people from across the country. U.S. Environmental Protection Agency (EPA) regulations only permit the use of chlormequat on ornamental plants and not food crops grown in the U.S. As explained in the journal article, “In April 2018, the U.S. EPA published acceptable food tolerance levels for chlormequat chloride in imported oat, wheat, barley, and some animal products, which permitted the import of chlormequat into the U.S. food supply.” In 2020, EPA increased the allowable level of chlormequat in food. Then in April 2023, EPA proposed allowing the first-ever U.S. use of chlormequat on barley, oat, triticale (a hybrid of wheat and rye), and wheat. Existing regulatory standards explain the […]

A recently completed study (available in preprint before peer review) identifies the development of what the authors term Toxicant-Induced Loss of Tolerance (TILT), the constellation of symptoms associated with chemical exposures.
