chlorinated hydrocarbons

insecticidal substances which are no longer recommended for use on food animals because of their persistence in animal tissues and entry into the human food chain. Many of them still find industrial and nonanimal use and poisoning of animals can occur. Poisoning is manifested by nervous excitement, tremor, convulsions and death. Includes aldrin, benzene hexachloride, chlordane, DDD, DDT, heptachlor, isodrin, lindane, methoxychlor.
