title: Distribution and metabolism of 3H-2,5,2',5'-tetrachlorobiphenyl in rats.
abstract: Distribution and metabolism of an isomeric polychlorinated biphenyl were determined in rats. Over 70% of a single dose of 3H-2,5,2',5'-tetrachlorobiphenyl was excreted in the feces and another 13% in the urine during a 14-day period. Adipose tissue, blood, skin, and liver were found to contain low levels of the compound. Over 90% of the excreted tritiated compound was found to be metabolized, the major metabolite being identified as 3-OH-2,5,2',5'-tetrachlorobiphenyl. All of the unmetabolized 2,5,2',5'-tetrachlorobiphenyl was eliminated by the alimentary route.
