Chlorpyrifos

On the heels of last week's strong report from pediatricians highlighting the harms pesticides can cause children's developing minds, a new study finds that pesticides are clearly harming adult brains, too.

In the "meta-analysis" published in Critical Reviews in Toxicology, scientists reviewed 14 separate studies of neurobehavioral changes linked to low-level organophosphate (OP) pesticide exposure. They found that workers exposed to OPs — particularly over long periods of time — had reduced working memory and were slower to process information.

I keep reading about how boys have a harder time at all levels of school than girls. It turns out there may be more going on than the commonly held argument that teaching styles are more conducive to girls' success. Boys may also be at a biological disadvantage — new research shows that their brains may be more vulnerable to harm from pesticides.

As a mom of an infant boy, this has me seriously worried.

Earlier today, EPA announced new restrictions on the insecticide chlorpyrifos, a known brain toxicant linked to learning disabilities in children and commonly sprayed on corn, oranges, grapes and almonds, among other crops.

These new protections are a step in the right direction, and will significantly reduce the amount of chlorpyrifos applied to fields and orchards. But more protection is needed to safeguard the health of farm communities and children who live, learn and play near pesticide application sites.

EPA Takes “Big Step” on Brain Toxin

Agency proposes new protections for rural communities from chlorpyrifos, but keeps pesticide on the market

When a pregnant woman is exposed to low levels of a commonly used pesticide, the architecture of her developing infant's brain may be irreversibly damaged. This according to researchers who for the first time used MRI testing to see structural evidence of harm from exposure to the insecticide chlorpyrifos during fetal development.

Researchers report that the changes in brain structure they observed were consistent with the learning and developmental effects (including reduced IQs) that have been linked to chlorpyrifos. The effects were observed at exposure levels well below those considered harmful by EPA.
