Abstract
Catfish was obtained from Ewekoro River, Wagunna River, fish ponds A and B for proximate and the quantification of the presence of lead, cadmium, manganese and chromium in the fish muscle which was achieved using Atomic Absorption Spectroscopy. The levels of cadmium, lead, manganese and chromium in the muscle of catfish from Ewekoro River were 1.34, 0.31, 1.62 and 0.24 mg/kg and 1.01, 0.22, 1.56 and 0.12 mg/kg for Wagunna River respectively. Cadmium was not detected in the water samples of the fish ponds A and B as well as in the muscles of catfish. In most of the fish samples, the concentrations of the selected metals in the muscle of the fish raised in Rivers were found to be higher than the minimum values recommended by standard organizations.
