Recently, public confidence has been eroded by a report highlighting the risks associated with exposure to environmental contaminants such as heavy metals, which are known to accumulate in fish. The aim of this study was to evaluate the contamination by heavy metals in fish from the Mediterranean coast, 5 samples were obtained in 5 states (Algiers, Annaba, Bejaia, Tunis, Monastir). Cd and Pb were measured in the flesh of the fish in a spectrophotometer. The results obtained after analysis of our samples, we conclude that: the fish of the Mediterranean coast are contaminated by cadmium (Cd) and lead (Pb) because the concentrations of heavy metals in fish analyzed are superior to standards existing (OJ JECFA and FAO / WHO).
