Abstract
1. Following the administration of daily oral doses (1 mg/kg) of 2,5,4′-trichloro-[14C]biphenyl to rats for 14 days, the compound was rapidly excreted, only small amounts 3-4%) being stored in the organs.
2. The majority of the biphenyl was metabolized (>85%) and the major metabolites excreted were identified as hydroxy-, dechloro- and conjugated derivatives.
