Organophosphate

An organophosphate (sometimes abbreviated OP) or phosphate ester is the general name for esters of phosphoric acid. Organophosphates are the basis of many insecticides, herbicides, and nerve agents. The United States Environmental Protection Agency lists organophosphates as very highly acutely toxic to bees, wildlife, and humans. Recent studies suggest a possible link to adverse effects in the neurobehavioral development of fetuses and children, even at very low levels of exposure.
