MSH: A polychlorinated pesticide that is resistant to destruction by light and oxidation. Its unusual stability has resulted in difficulties in residue removal from water, soil, and foodstuffs. This substance may reasonably be anticipated to be a carcinogen: Fourth Annual Report on Carcinogens (NTP-85-002, 1985). (From Merck Index, 11th ed),CSP: insecticide that came into prominence during and after World War II; for a time it proved very effective, but insect populations rapidly developed tolerance for it, hence much of its original effectiveness has been lost; general usage is now widely discouraged because of the toxicity that results from the environmental persistence of this agent.,NCI: A white, odorless and tasteless, very stable, water-insoluble, synthetic, crystalline chlorinated hydrocarbon that is soluble in most organic solvents, fat and oils and tends to accumulate in ecosystems. DDT was once widely used as a pesticide to control insects in agriculture and to control malaria, typhus and body lice,
