Metal Concentrations in Tissues of Pseudolithus Senegalensis, (Croacker Fish) and Ethmalosa Fimbriata (Bonga Fish) Obtained from Carter Bridge River and Makoko River, Lagos State, Nigeria

his study assessed the concentrations of cadmium, lead, manganese, copper and iron in the tissues of commercially important Croacker fish (Pseudolithus senegalensis) and Bonga fish (Ethmalosa fimbriata) obtained from Carter Bridge river and Makoko river,in Lagos State, Nigeria. These metals were determined using Perkin-Elmer Analyst 300-Atomic Absorption spectroscopy (AAS). Heavy metal content varied significantly (p<0.05) depending on fish species. This study revealed that the concentration of cadmium and lead in Pseudolithus senegalensis and Ethmalosa fimbriata tissues were above the maximum acceptable concentrations for human consumption, thus precaution need to be taken on order to prevent future contamination.
