    ABSTRACT
    The current work aims to study the metallic contamination of two targeted sampling sites located near the main effluent discharge points on the Algerian coasts: the industrial Gulf of Arzew (Polluted Site: S1) and Oued Elma Kristel (Reference Site: S2), using a metallic pollution indicator biological species Mytilus galloprovincialis Lamarck, 1819 (Bivalvia Mytilidae), collected at a depth of 2 to 3 m seasonally in 2016. Concentrations of metals and metallic indices of the trace elements (Lead, Zinc, Nickel, Iron and Copper) obtained in the soft tissues of the mussel are determined and related to the seasons and sampling sites of the current year. In site S1, the statistical study revealed significant contamination by Nickel (67.63–70.28 mg.kg-1), Iron (118.18–125.45 mg.kg-1) and Copper (6.11–6.62 mg.kg-1) in summer, Zinc (213.39- 255.33 mg.kg-1) in winter and Lead (7.55–8.78 mg.kg-1) in autumn. However, site S2 recorded high levels of Lead (8.36–37.63 mg.kg-1) and Zinc (67.03–405.37 mg.kg-1) during the year.
