Several months ago, Harvard researchers reported a link between pesticides and attention deficit disorder in children. The kids with higher levels of pesticide breakdown products in their urine were about twice as likely to have ADHD. Now a study from California demonstrates that pregnant women exposed to higher-than-average levels of pesticides are more likely to give birth to children who develop ADHD. The researchers measured pesticide metabolites in urine and found that the higher the levels in the mothers during pregnancy the greater the risk for attention deficit in the children, especially boys.
