Metal composition of Clarias gariepinus consumed in Makurdi and its environs
A study was conducted to determine the concentrations of nine heavy Metals (Cadmium, lead.Copper, Chromium, Iron, Zinc, Selenium, Nickel and Aluminum) in gills, muscles and skin of Clarias gariepinus within three different locations (Kuatansule, Wadata and UAM fish) with the use of standard flame Atomic Absorption Spectrophotometry Techniques. Iron was found in high concentration in all the sites with the gills having the highest concentration while lead. Cadmium, Selenium, Nickel and Aluminum were not detectable. Significant differences in metal concentrations were observed between locations with UAM fish farm having the highest metal concentration. It is concluded that concentration, of heavy metals found in selected organs of Clarias gariepinus were within tolerable limits as recommended by FAO.
