Abstract

Rainbow trout (Oncorhyncus mykiss) were exposed to the 14C- labeled lampricide 3-trifluoromethyl-4-nitrophenol (TFM) (2.1 mg/L) or niclosamide (0.055 mg/L) in an aerated static water bath for 24 h. Fish were sacrificed immediately after exposure. Subsamples of skin-on muscle tissue were analyzed for residues of the lampricides. The primary residues in muscle tissue from fish exposed to TFM were parent TFM (1.08 ?? 0.82 nmol/g) and TFM-glucuronide (0.44 ?? 0.24 nmol/g). Muscle tissue from fish exposed to niclosamide contained niclosamide (1.42 ?? 0.51 nmol/g), niclosamide-glucuronide (0.0644 ?? 0.0276 nmol/g), and a metabolite not previously reported, niclosamide sulfate ester (1.12 ?? 0.33 nmol/g).
