A new study has shown that children with higher levels of pesticide metabolites (chemicals generated when the body breaks down pesticides) were more likely to be diagnosed with attention deficit hyperactivity disorder (ADHD).
1) Approximately 40 organophosphate pesticides are approved by the Environmental Protection Agency (EPA) for use in the US. In 2001, approximately 73 million pounds of organophosphate pesticides were used.
2) According to the National Academy of Sciences, the major source of exposure of infants and children to pesticides is through their diet.
3) Children are at greatest risk for pesticide toxicity because they have developing brains and because they are smaller so the amount of exposure (dose) per body weight is greater.
1) From about 1,000 kids ages 8-15, approximately 10% had been diagnosed with ADHD.
2) Children with higher levels of pesticide metabolites in their urine were more likely to have been diagnosed with ADHD, even after considering other factors such as age, race/ethnicity, poverty, etc.
3) For the most commonly detected pesticide metabolite, children with levels in the top half of the sample were twice as likely to have been diagnosed with ADHD compared to children without detectable levels of that compound.
