Metal Contamination of a Fish Species (Mugil curema) of the Beach of Soumbedioune (Dakar/Senegal)

This present work consists in studying the metal contamination of the beach of Soumbédioune, located at the western frontage of the Dakar area. This site, unloading place of fishery products, includes the channel IV which drains urban rejected waters. We determined the concentrations of the metal elements (Fe, Zn, Cr), in Mugil curema with spectrophotometry UV-visible. Metal elements can be very dangerous for human health when they are present in the environment at high concentrations. Thus the study of the metal contamination in the marine organism, in particular fish, makes it possible to envisage a possible contamination of the man. The results obtained show that the concentrations of the metal elements vary according to the weight and the size of the mullets. The maximum content in chromium of 133 µg/g was obtained with Mugil curema1, that out of iron was of 85.5 µg/g with Mugil curema8 and that out of zinc obtained with Mugil curema1 was of 150 µg/g. However the found values are definitely higher than the standards established by FAO and the EEC.
