pesticide organophosphoré

OBS: Terme en usage à la Commission canadienne des grains.

CONT: In health, agriculture, and government, the word ""organophosphates"" refers to a group of insecticides or nerve agents acting on the enzyme acetylcholinesterase (the pesticide group carbamates also act on this enzyme, but through a different mechanism). The term is used often to describe virtually any organic phosphorus (V)-containing compound, especially when dealing with neurotoxins ... Organophosphate pesticides (as well as sarin and VX nerve gas) irreversibly inactivate acetylcholinesterase, which is essential to nerve function in insects, humans, and many other animals. Organophosphate pesticides affect this enzyme in varied ways, and thus in their potential for poisoning.
