Pesticides during pregnancy could lower babies' IQ

Posted:
WATERLOO (KWWL) -

Women exposed to pesticides during pregnancy could have children with low IQ scores.

Three studies released yesterday show an association between prenatal pesticide exposure and low intelligence scores at age seven.

Researchers at the University of California Berkeley followed more than 300 children since before birth.

They found the more pesticides their mothers were exposed to during pregnancy, either from produce or home use of pesticides, the lower their scores on IQ tests.

Exposure to pesticides after birth did not impact intelligence, a sign that fetal brain development is particularly sensitive.

Overall, pesticide use in the U.S. has been going down.
