Organophosphates are a group of human-made chemicals that poison insects and mammals. Organophosphates are the most widely used insecticides today.They are used in agriculture, the home, gardens, and veterinary practice. Organophosphate insecticides (such as diazinon) are one type of pesticide that works by damaging an enzyme in the body called acetylcholinesterase.This enzyme is critical for controlling nerve signals in the body. The damage to this enzyme kills pests and may cause unwanted side effects in exposed humans.All organophosphates have a common mechanism of toxicity and can cause similar symptoms in humans who have too much exposure.rine samples from participants in the Churchill County leukemia study were analyzed for organophosphate insecticides and their breakdown products (metabolites). The metabolites are not toxic, but show that exposure to organophosphates occurred in the few days before testing.
