Organochlorine
pesticides are insecticides composed primarily of carbon, hydrogen
and chlorine. Because they break down slowly, organochlorine
pesticides can remain in the
environment long after they are applied and in organisms long after
exposure.
The most
notorious organochlorine is the insecticide DDT (Dichloro diphenyl
trichloroethane). Promoted as a "cure all" insecticide in the 1940s,
DDT was used globally for many years in agricultural production and mosquito control.
