Sažetak
Distribution of trace elements in the coastal sea sediments of Punat bay in the Northern Adriatic have been investigated. The concentrations of 16 elements (ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Rb, Sr, Y, Zr and Pb) were measured by energy dispersive XRF. Two predominant types of sediments were observed: the first (sediment "A"), which consists of 87% pelitic fraction and the second (sediment "B"), where coarse-grained fraction (0.315-0.1 mm) prevails. Enrichment factors had elevated values in two upper-most segments for the elements Cu, Zn and Pb in sediment "A". The highest percentage of exchangable fraction with respect to the total composition was characteristic for Cr, Cu and Zn in both types of sediments.
