Abstract:

Levels of trace metals in edible mussels of five fish samples Pampus Argenteus, Pampus chinensis, Parastromateus niger, Protonibea diacanthus, and Otolithes Tuber, of northwest costal area of Karachi were studied by AAS technique. All estimation was made on wet basis. Iron was found maximum (0.890-9.395 μg/g) amount all species and cadmium was found as minimum (0.015-0.0414 μg/g). Levels of other metals varied in the range of 0.249-0.986, 0.137-0.49, 0.29-0.929, 0.391-0.986 and 0.081-0.243 μg/g for As, Co, Cu, Mn & Pb respectively in the muscles of various fishes investigated. Maximum concentrations of all metals were found in Protonibea diacanthus except Cd, which was found maximum in Parastromateus niger, and pampus argenteus was found to contain the minimum amount of all metals. Various fish contain different concentration of all metals.
