Assessment of Heavy Metals (Fe, Cu and Ni) Contamination of Seawater and Mussel, Mytilus Galloprovincialis, from Al Hoceima Moroccan Coasts

EasyChair Preprint 2856

Abstract

In the present work, both seawater and mussels (M. galloprovincialis) were collected monthly from the mussel farm located along the coastline of Al Hoceima (Morocco) and their heavy metal concentrations (Fe, Cu, Ni) were determined using inductively coupled plasma – optical emission spectrometry (ICP-OES). The trace metals found in the mussel tissues are much higher than those found in the environment. The order of the abundance of metals in the mussels is Fe > Cu > Ni. The pattern of the temporal variation of mussel trace metal levels was similar among stations with higher values during the months of winter season and lower during the months of summer period. Heavy metals uptake is dependent on both environmental and biological factors. Results obtained in this study for Fe, Cu and Ni, indicate that the species under investigation poses no health hazard to consumers because its trace metal contents remain within the permissible range established by various international guideline for safe human consumption. Our study, indicate that bivalve molluscs can be used as sentinel bioindicators in marine environments impacted by heavy metals in this area of the Moroccan coastline.
