This study assessed the concentrations of cadmium in the gills, livers and muscles of a commercially important tilapia fish ( Sarotherodon melanotheron) from Aby Lagoon in Adiak谷, Cˋte d＊Ivoire, between January and December, 2010. The organisms were grouped into two composite samples (juvenile and adult) of five individuals. Levels of cadmium were determined in tissues using Perkin-Elmer (AAnalyst 200) Atomic Absorption Spectrophotometry (AAS) after a digestion method. Fish muscle appeared to have a significantly higher tendency to accumulate cadmium (1.19每5.18 米g/g dw) while gills and livers had minimum concentrations (0.07每1.32 and 0.12每1.25 米g/g dw). This study has revealed that the concentrations of Cd in Sarotherodon melanotheron muscle tissue were above the maximum acceptable concentrations for human consumption, thus precautions need to be taken in order to prevent future contamination.
