Study Strengthens Link Between Prenatal Pesticide Exposure and Autism

‘Autism Spectrum Disorder [ASD] affects about 1 in 68 children in the United States, and a combination of genetic and environmental factors, along with complications during pregnancy have been associated with ASD diagnoses. A new study from the National Institute of Environmental Health Services has strengthened the link between prenatal exposure to agricultural pesticides and ASD. The study’s findings have been published in the journal Environmental Health Perspectives….

The researchers compared addresses during pregnancy to state records of applications of organochlorines, organophosphates, pyrethroids, and carbamates within 1.25 km, 1.5 km, and 1.75 km from those addresses. About a third of the 970 study participants lived within 1.5 km 0.9 miles of pesticide applications during pregnancy. While proximity to any of the four classes of pesticide resulted in an increased risk of a child with ASD or DD, some of the chemicals presented a greater risk at different stages during pregnancy.’ (IFLScience).
