Abstract: Assessment of heavy metals concentration in O. niloticus and C. nigrodigitatus was carried out in Calabar, Cross River State.The people of Cross River State depend on fish and other aquatic products for their source of protein, thus the need to verify the safety of some commonly consumed fish which are significant food in Calabar. Samples were purchased from artisanal fishermen from the landing sites of Great Kwa River at EsukAtu and Anantigha beach and the concentrations of heavy metals (Nickel, Copper, Chromium, Cadmium and Lead) inliver; gill and muscle were analyzed using Atomic Absorption Spectrophotometry (AAS). Results obtained from the analysis of trace metals in the organs in O. niloticusshowed the presence of the metals in different organs of the fish at different levels of concentration.
Keywords: Heavy metal, pollution, Oreochromis niloticus, Chrysichthys nigrodigitatus and Great Kwa River.
