Soils and earthworms and other soil invertebrates were collected from 67 agricultural fields in eight States. Samples were analyzed by gas chromatography for DDE, DDD, DDT, aldrin, dieldrin, endrin, heptachlor, heptachlor epoxide, and gamma-chlordane insecticides. Organochlorine insecticides in soils averaged 1.5 ppm, dry weight, and in earthworms, 13.8 ppm.

Organochlorine Pesticides (axysanalytical

Organochlorine Pesticides (OCs) are a group of human-made chemicals that contain carbon, hydrogen and chlorine. It was discovered in the 1940s that some OCs are toxic to insects. OCs have been used to kill insects that carry disease and that are pests on crops. A well known OC pesticide is DDT (dichlorodiphenyl-trichloroethane).
