[Trace metals: zinc and copper in Tunisian littoral fishes].

Investigations have been carried out in order to find out whether zinc and copper are or not accumulated in flesh and organs of some edible fish of a polluted area, namely Sfax. Tracking zinc and copper was our first aim, the second was the determination of an organotropism of the two metals. Finally, our results, would help stating whether or not Sfax-shore is polluted with zinc and copper.
