Biomonitoring of trace metal contamination in El Mellah Lagoon (Algeria) using cockle Cerastoderma glaucum (Bivalvia: Cardiidae).

This work aims to investigate the trace metal contamination of El Mellah Lagoon by assessing their accumulation levels in the tissues of the brackish water cockle Cerastoderma glaucum (Bivalvia: Cardiidae). Our findings show that copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) concentrations in cockles ranged between 0.81-2.09, 4.12–6.72, 0.09–0.15, and 0.39–0.76 mg/kg soft tissue dry weight respectively, in ascending order of: Cd< Pb< Cu< Zn. Statistical analysis reveals significant seasonal variations in measured metals, with the highest values all recorded in autumn but remaining well below the recommended guide values. Overall, our study excludes the existence of an ecotoxicological threat linked to the presence of essential (Cu, Zn) and toxic (Cd, Pb) metals in the cockles' flesh.
