Distribution of Trace Elements in the Coastal Sea Sediments of Maslinica Bay

Spatial distributions of trace elements in the coastal sea sediments and water of Maslinica Bay (Southern Adriatic) were investigated. Trace elements distributions in five granulometric fractions were determined for each sediment sample. Bulk sediment samples were also subjected to leaching tests. Elemental concentrations in sediments, sediment extract and sea water were measured by source excited energy dispersive X-ray fluorescence (EDXRF). Concentrations of the elements Cr, Cu, Zn, and Pb in bulk sediment samples taken from Maslinica Bay were 2.1 to over six times enriched when compared with the background level determined for coarse grained carbonate sediments. A low degree of heavy metal leaching determined for bulk sediments pointed to strong bonding of heavy metals to sediment mineral phases.
