Popis: This study has been undertaken to evaluate the physicochemical water quality of the Sfax-Kerkennah plateau. Thirteen surface seawater and sediment samples were collected. Different tests, including turbidity, suspended matter (MES), dissolved organic carbon (DOC), and nutritive salts (i.e. total phosphorus “Ptot” and nitrate “NO3”) were used. Trace metals (Zn, Ni, Cu, Cd, and Fe) were also analyzed by using Inductively Coupled Plasma-Atomic Emission Spectrometry. The results indicated high values of turbidity, suspended matter, DOC, and nutritive salts in seawater samples near the coastal line of Sfax City. Those high values seemed to be related to the huge volumes of domestic wastewater discharged in the ecosystem. Trace metals analyzed in surface seawater and sediment samples showed also significant concentrations at the same sites (close to Sfax coast). The study of the metal spatial distributions in sediment samples refined by complementary approaches including enrichment factors and geoaccumu...
