Chlorpyrifos

Prairie bird populations are falling in many Midwestern states, from ring-necked pheasants to horned larks to sparrows. Scientists now say insecticides are a primary culprit.

Minnesota birds are hardest hit with 12 species in decline, followed by Wisconsin with 11, and Illinois, Michigan, Montana, Nebraska and New York with nine affected species each.

Children living near banana farms in Costa Rica face widespread exposure to the neurotoxic pesticide chlorpyrifos — at levels EPA would consider unsafe.

In a study measuring a chlorpyrifos biomarker in children's bodies, researchers found that nearly 100% of the samples exceeded the EPA safety limits set with children's safety in mind. Urine samples were taken from kids living near banana plantations or plantain farms in the Talamanca region.

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.
