Analytical data as related to sediment types and water depth, Adriatic Sea

A preliminary set of heavy metal analyses from surface sediment samples covering the whole Adriatic Basin is presented, and their significance in terms of pollution is discussed. The core samples were analysed for Fe, Mn, Cr, Cu, Ni, Pb, Zn, P, organic carbon, Ca- and Mg-carbonate, and their mineralogical composition and grain size distribution were determined. All heavy metal concentrations found can be attributed to natural sedimentological processes and are not necessarily to be interpreted as indications of pollution.
