ABSTRACT:
Heavy metals in our environment have been of great concern because of their toxicity at concentrations above permissible limit. Heavy metals enter the environment through different ways such as industrial activities etc. The fish samples cat fish (Conydors semiaquicus) and Tilapia fish (Oreochromis niloticus) were collected from Ndibe-Beach in Afikpo North Local Government Area of Ebonyi State. The fish were carefully deselected for digestion and the levels of heavy metals were determined using “GBC sent AA” atomic absorption spectrophotometer. Metals present in the fish samples were analyzed in the order: Cr, Cu, Zn, As, Cd, Hg and Pb. It was observed that Cr, Cu, Zn, Cd and Pb were detected but AS and Hg were not detected. Zinc has the highest concentration of 46.0mg/kg in Tilapia (Oreohromis niloticus) and 50.3mg/kg in catfish (Conydors semiauitus). Cr has and 3.20mg/kg in catfish (Conydors semiauitus) and concentration of 3.80mg/kg in Tilapia fish (Oreochromic semiaquilus). The howest concentration were detected in Pb which is 1.6mg/kg in Tuapia fish (Oreochromis niloticus) and 1.2mg/kg in catfish (Conydros semiqauilus). The concentration range of the heavy metals: Cu > Zn > Cr > Cd > Pd for Tilapia fish while for Cat fish the range is: Cu > Cr > Cd > Pb. The level of the four heavy metals detected were High compared to the W.H.O standard.
