By using simultaneous exposure to Pb and Cd, and exposure to Cd after Pb acclimation,the interaction of the two metals on the branchial uptake and hepatic and renal accumulation in goldfish, Carassius auratus were studied.In the fish exposed to mixtures of constant Cd at 4\^448μmol/L and varied Pb at 0,1\^448,2\^896,4\^344,5\^792,7\^239,and 8\^687 μmol/L in artificial freshwater for ten days,increased branchial uptake and renal accumulation,but not hepatic accumulation,of Pb were observed as Pb concentr...
