Metabolism of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane, and 1-chloro-2,2-bis(p-chlorophenyl)ethene in the hamster. 1983

B Gold, and G Brunk

The urinary metabolites of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (DDD), and 1-chloro-2,2-bis(p-chlorophenyl)ethene in female hamsters are reported. The principal metabolite of both DDT and DDD is 2,2-bis(p-chlorophenyl) acetic acid. DDT- and DDD-treated animals also excreted small amounts of DDD, 1-chloro-2,2-bis(p-chlorophenyl)ethene, 1,1-dichloro-2,2-bis-(p-chlorophenyl)ethene, 2-hydroxy-2,2-bis(p-chlorophenyl)acetic acid, and 2,2-bis(p-chlorophenyl)ethanol. 1-Chloro-2,2-bis(p-chlorophenyl)ethene is metabolized to afford significant amounts of 2,2-bis(p-chlorophenyl)acetic acid, 2,2-bis(p-chlorophenyl)-ethanol, 2-hydroxy-2,2-bis(p-chlorophenyl)acetic acid, 2,2-bis-(p-chlorophenyl)acetaldehyde, and 1,1-bis(p-chlorophenyl) ethan-1,2-diol. These results indicate that the metabolic disposition of DDT in the hamster, a species refractory to DDT tumorigenicity, is very similar to that observed previously in the mouse, a species sensitive to DDT tumorigenicity. The one exception is that the hamster is not nearly as efficient as the mouse in converting DDT to 1,1-dichloro-2,2-bis(p-chlorophenyl)ethene, a metabolite that is tumorigenic in both species.

D003634	DDT	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).

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001711	Biotransformation	The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
