Acute exposure of Oreochromis aureus to cadmium or lead resulted in different tissue accumulation profiles. Trunk kidney accumulated the highest lead concentrations of all tissues analysed after 24‐h or 1‐week exposure to 0.1 mg l –1 lead as PbCl 2 while exposure to 0.1 mg l –1 cadmium as CdCl 2 for 24 h or 1 week resulted in the highest accumulations of cadmium in the intestine. Caudal muscle consistently accumulated the lowest levels of lead or cadmium after a 1‐week exposure period.
