A growing body of evidence is suggesting that exposure to organophosphate pesticides is a prime cause of attention deficit hyperactivity disorder, ADHD. The findings are considered plausible to many experts because the pesticides are designed to attack the nervous systems of insects. It is not surprising, then, that they should also impinge on the nervous systems of humans who are exposed to them. Forty organophosphate pesticides are registered in the United States, with at least 73 million pounds used each year in agricultural and residential settings. ADHD is thought to affect 3% to 7% of American children, with boys affected more heavily than girls. The newest study, reported [on August 19] in the journal Environmental Health Perspectives, examines the effects of both prenatal and childhood exposure to the pesticides. Epidemiologist Brenda Eskenazi of UC Berkeley and her colleagues have been studying more than 300 Mexican American children living in the heavily agricultural Salinas Valley. After correcting the data to account for lead exposure and other confounders, they found that each tenfold increase in pesticide levels in the mothers' urine was associated with a fivefold increase in attention problems as measured by the assays.
