| Popis: | The present work aims to track the natural and anthropogenic metals input into the lagoonal complex of the Oualidia-Sidi Moussa and assess their sediment quality by applying the International sediment quality guidelines. We compared the concentrations of metals (Cu, Cr, As, Zn, Ni and Pb) measured in the sediment of the lagoonal complex of the Oualidia-Sidi Moussa between 1976 and 2017 with a range of sediments quality guidelines values. The comparison showed a decreasing trend of metals concentration in the last decade in the Oualidia lagoon except for As, Cr and Cd. Similarly, in the Sidi Moussa lagoon, both Cd and Cr displayed higher concentrations exceeding the threshold effect level values signifying possible toxic risk for marine biota living. This review revealed the effects of irresponsible growth of human activities on the environment, threatening natural resources and human well-being.
