Vol. 341 no. 6147 pp. 740-741
DOI: 10.1126/science.341.6147.740 Three cohort studies in the United States are tracking the long-term consequences on the developing brain of pesticide exposure during pregnancy and the early years of life. The studies are finding troubling effects, such as IQ deficits and ADHD-like behavioral problems. Some evidence also suggests pesticides may interfere with the normal sexual development of the brain.
