| dichlorodiphenyltrichloroethane | 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) |
| dichloroethylenes | Toxic chlorinated unsaturated hydrocarbons. Include both the 1,1- and 1,2-dichloro isomers. Both isomers are toxic, but 1,1-dichloroethylene is the more potent CNS depressant and hepatotoxin. It is used in the manufacture of thermoplastic polymers. (12 Dec 1998) |
