chlorpyrifos

Washington regulators must soon consider rules to limit the use of a controversial pesticide that can cause neurological and health problems, especially in young children. A bill passed by state lawmakers this session didn’t outright ban the pesticide, as health and farmworker activists had proposed.

The chemical’s especially dangerous for babies and small children because it can have lasting neurological effects. Chlorpyrifos can blow from orchards into nearby houses; parents who work in orchards can transport the chemical home on their clothes and in their cars; and chlorpyrifos can make its way into developing fetuses through umbilical cord blood.
