| Title | Heavy metals in marine sediments of Taranto gulf (Ionian Sea, Sorthern Italy) |
| Abstract | Al, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Ti and Zn concentrations have been determined in surface sediment samples collected in the Taranto gulf (Ionian sea, Southern Italy) in order to evaluate their levels and spatial distribution in this important area of the Mediterranean sea. For various metals, the geoaccumulation index has been calculated as a criterion to assess if their concentrations represent contamination levels or can be considered as background levels. The results show that metals concentrations in sediments can be considered near the background levels found in the Mediterranean sea. Analytical results have been elaborated by using a Geographical Information System (GIS) software to show metals accumulation areas. Using multivariate statistical analysis we evaluate the possibility to distinguish the sampling stations, in relation to their geographical position. Results have showed metals distribution in the Taranto gulf is principally influenced by industrial and urban wastes, located mostly in the Northern coastal area of the Ionian sea. Rivers in the Basilicata region and prevailing anticlockwise marine currents are further factors influencing metal accumulation in sediments. |
