Abstract: The study was carried-out over a six months period. Seventy-two adult of Clarias gariepinus, thirty-six water and sediments samples were collected throughout. Lead was not detected in the muscles through-out the study. The accumulation of Cr and Ni in Clarias gariepinus muscles came mainly from sediments, Cu from both sediments and water, Fe mainly from sediments and slightly from water and Zn slightly from both sediment and water as shown by the different relationship between metals in muscles and the abiotic factors (water and sediments). Fish muscles were slightly polluted with Cr, Fe, Ni and Mn, while the water shows slightly polluted with Mn, Cd and Ni, and sediments shows slightly polluted with Cr, Cd, Ni and Fe, making it unsafe. It is important for regulatory agencies to monitor and enforce policies against some careless activities in the River, and also to fund more environmental related studies in this area.
