UC Berkeley’s School of Public Health measured the IQs of 7-year-olds whose mothers in the agricultural Salinas Valley in California. 

…For every 522 pounds of chemical pesticides applied less than 0.6 miles from where the pregnant mother lived, the child’s IQ declined by 2 points, and the child’s verbal reasoning score declined by 3 points. 

…A study published in the journal Pediatrics in 2011 found a link between pesticides in food and attention deficit hyperactivity disorder (ADHD). Researchers took urine samples 1,140 children and evaluated them for the symptoms of ADHD. 

They found that the children who met the criteria for ADHD had significantly higher levels of a breakdown product of organophosphate pesticides in their urine.

New study suggests pesticides could lower IQ

hmmm
