Rainbow trout were exposed to 8 h episodes of either Cd (0.1 or 0.2 mg/L) or Cu (0.1 or 0.6 mg/L) at pH 7. Gill, liver, mucus, blood, skin, muscle, and body remainder were examined for metal content during and after exposure. Accumulation of Cd occurred mostly in the gill, liver, mucus, and muscle,
Rainbow trout, Oncorhynchus mykiss, were fed on a commercial feed enriched with either Cd or Cu for 32 days and allowed to recover on normal food for 12 days. The body burden of fish fed Cd-enriched diet increased from about 0.05 to 0.39 micrograms/g wet weight, reflected by elevation in the Cd cont
