title: Distribution of metals in organs of Clarias gariepinus, Heterobranchus bidorsalis, and Chrysichthys nigrodigitatus from the Offin River at Dunkwa-on-Offin, Ghana.
abstract: All heavy metals are potentially harmful to most organisms at some level of exposure and absorption. Concentrations of Co, Cr, Cu, Ni, Zn, Hg, Cd, As, and Pb were determined by atomic absorption spectrophotometry (AAS) in three fish species (C. gariepinus, C. nigrodigitatus, and H. bidorsalis) from the Offin River in Dunkwa township, Ghana. In the fish species, gills, livers, and muscles were analyzed. The metal that recorded the highest concentration was Zn, which was highly accumulated in the liver of C. gariepinus, but had the lowest concentration in the muscles of C. nigrodigitatus.
