Stehly, G. R., and Hayton, W. L., 1989, Metabolism of pentachlorophenol by fish: Xenobiotica, v. 19, no. 1, p. 75-81. Abstract: Interspecies variability in the metabolism of pentachlorophenol (PCP) was investigated by exposing rainbow trout, fathead minnows, sheepshead minnow, firemouth, and goldfish to water-borne super(14)C-PCP for 64 h. The amounts of metabolites in bile and exposure water were species-dependent; all of the metabolites excreted into the water were sulphate conjugates while bile was enriched in glucuronide conjugates. Biliary excretion accounted for less than 30% of the total PCP metabolites. Biliary metabolites alone were a poor indication of the metabolites produced and of the major routes of elimination.
