organophosphates
Toxic phosphorus compounds
Organophosphates are a class of chemical compounds containing phosphorus, widely used as pesticides and insecticides.
They work by disrupting the nervous system, which makes them effective against pests but also toxic to humans and animals: Organophosphate poisoning requires immediate medical attention.
Some were developed as nerve agents for chemical warfare.
Farmers and agricultural workers face the highest exposure risk.
