Bioaccumulation and health risk assessment of trace elements in<i>Mytilus galloprovincialis</i>as sea food in the Al Hoceima coasts (Morocco)

The monthly variations in metal concentration of Cadmium (Cd), Zinc (Zn) and Chromium (Cr) were determined tissues Mytilus galloprovincialis seawater obtained from the mussel farm installed along Al Hoceima coasts, during sampling period 2018. heavy metals encountered bivalves higher than those observed their environment with a decreasing order Zn &gt; Cr Cd. results also showed trend for studied summer campaign. maximum values wet periods. trace due to environmental parameters physiological state bivalves. Our revealed that average concentrations pollutants found M. below limits allowed by Food Agriculture Organization United Nations (FAO) which are 2.0, 1000 1.0 mg/kg, Cd, Cr, respectively molluscan shellfish human consumption. Therefore, elements present shore mussels do not represent risk health associated consumption, even bioaccumulation. work highlights potential use Biomonitoring metallic this region northern Moroccan coasts.
