Study Malathion Linked To Childrens Adhd

Kids fed fruits and veggies laced with pesticides may run a higher risk of developing attention deficit hyperactivity disorder. That disturbing find comes from Harvard University's School of Public Health, which analyzed urine tests and other health data gathered from a federal health survey. The study found a link between the children whose urine held higher-than-normal traces of the pesticide malathion and a diagnosis of ADHD. If their malathion levels were above the median for the whole group, they were twice as likely to have ADHD than their malathion-free peers.

 Malathion is the most commonly used insecticide in the U.S. It's long been known to cause developmental delays in the children of farmworkers, who are exposed to the stuff as it's being sprayed. This was the first study to look at kids in cities and suburbs. Researchers say those kids are probably exposed through the foods they eat, particularly frozen berries.

 Researchers used data gathered from the federal National Health and Nutrition Examination Survey from 2000 to 2004. They followed up with interviews with the parents of the 119 kids with the behavioral disorder ADHD.
