ADHD LINKED TO COMMON PESTICIDE: A new study published in the journal Environmental Health has identified an association between a common pesticide, pyrethroid, and ADHD in boys.
Boys with detectable urinary 3-PBA, a biomarker of exposure to pyrethroids, were three times as likely to have ADHD compared with those without detectable 3-PBA. Hyperactivity and impulsivity increased by 50 percent for every 10-fold increase in 3-PBA levels in boys. Biomarkers were not associated with increased odds of ADHD diagnosis or symptoms in girls.
