(Beyond Pesticides, December 6, 2018) A recent analysis of annual drinking water quality reports has revealed that many community drinking water systems in the Midwest have seasonal exceedances of the allowable limit for the herbicide atrazine. Atrazine, linked to endocrine disruption, neuropathy, and cancer, is the second most widely used pesticide in corn growing areas, with over 73 million pounds applied to agricultural fields each year. A 2009 study by Paul Winchester, MD, professor of clinical pediatrics at Indiana University School of Medicine and a neonatologist at St. Francis Hospital in Indianapolis, linked birth defects to time of conception, with the greatest impact on children conceived when concentrations of atrazine and other pesticides are highest in the local drinking water. (See Reproductive Effects Peak with Pesticide Exposure.) During peak use, atrazine levels in drinking water have been recorded at three to seven times above the legal limit. In addition to the well documented impact on the environment, recent studies have linked prolonged pesticide exposure to not only shortened gestation and preterm birth for women, but also neurodevelopment delays in children. Ultimately, these unreported seasonal peaks may result in persistent adverse health impacts in impacted communities. The Safe Drinking Water Act (SDWA), enacted in 1974, […]

(Beyond Pesticides, December 6, 2010) A new study finds that exposure to dioxin in the womb can affect female reproduction for generations, reducing fertility and increasing the chance for premature delivery. Scientists from the Women’s Reproductive Health Research Center at Vanderbilt University School of Medicine examined the effects of a specific variety of dioxin on female mice and found that subsequent generations of the mice exposed to dioxin are at risk. The study, entitled “Developmental exposure to TCDD reduces fertility and negatively affects pregnancy outcomes across multiple generations,” was published in the journal Reproductive Toxicology. Dioxin refers to a family of chemicals linked to cancer, endocrine disruption, weakened immune systems and reproductive problems. They are persistent organic pollutants that bioaccumulate in humans and other animals, especially in fatty tissue, meaning that concentrations of dioxin in the body generally increase with age. So, even in very low doses, dioxins can cause health problems. Scientists in this study specifically looked at the variety of dioxin that is considered the most toxic, known as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). TCDD is a well-known contaminant of the herbicide 2,4-D, which was originally a part of the deadly chemical weapon Agent Orange. As such, TCDD is still found […]

(Beyond Pesticides, May 6, 2008) Pregnant veterinarians who have occupational exposures to pesticides, anesthetic gases or radiation may have twice the risk of miscarriage, according to a new study published in the May 2008 issue of the journal Occupational and Environmental Medicine. The study, “Maternal occupational exposures and risk of spontaneous abortion in veterinary practice,” looked at the experiences of 1197 female veterinarians working in clinical practice, who graduated from Australian veterinary schools between 1960 and 2000, responding to a questionnaire-based survey. There was a twofold increase in the risk of miscarriage in women veterinarians who use pesticides at work. The researchers found that there was also a twofold increase for those exposed to anaesthetic gases for more than an hour a week without using equipment to remove the gas from the air, and an 80 percent greater risk of miscarriage in those who performed more than five x-ray examinations per week compared with those who performed five or less. Veterinarians are often unable to leave the room whilst performing an x-ray because they have to hold the animal being x-rayed in order to restrain it. Adeleh Shirangi, Ph.D., author of the research from the Department of Epidemiology and Public […]
