| chlorophenothane | 1,1,1-Trichloro-2,2-bis(p-chlorophenyl)ethane;an 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. Synonym: chlorophenothane, dicophane. Acronym: DDT (05 Mar 2000) |
