A new study just released from Harvard University School of Public Health found that children with higher levels of the pesticide malathion in their urine had a greater risk of developing attention deficit hyperactivity disorder, or ADHD. The findings draw from a wider sample of the United States population with low levels of exposure to the pesticide, with researchers speculating that most exposure in children came through food. What are the biological effects of these potentially dangerous pesticides, and what are the ways to reduce contact with them?
