Bioaccumulation of nickel and vanadium in the tissues of the liver, kidney, gill, and intestine has been studied following 4 days and 30 days of exposure at sublethal concentrations of nickel and vanadium compounds in the catfish Clarias batrachus. Nickel and vanadium have been found to accumulate in all four tissues observed. High concentrations of nickel and vanadium have been found in the order kidney greater than gill greater than liver greater than intestine during the 4 days and 30 days treatment. A dose-response effect was seen, as the concentration of metals in the tissues increased with concentration and exposure time. The effect on bioaccumulation in the specific tissue provides a better basis for monitoring exposures than whole-body analysis.
