Trace metal accumulation in the sediment of the submarine cave "Zmajevo uho" (Soline bay, Croatia)

A vertical profile in a sediment core from the submarine cave "Zmajevo uho" has been analysed for granulometric composition, organic matter, carbonate contens and trace metal concentrations (Cd, Pb, Cu, Zn and Ni). The carbonate content and granulometric composition are interrelated indicating that sediments from the cave having more carbonates are usually coarse grained. The concentrations of all trace metals decreased down the sediment core and showed good correlation with organic matter content.The surface enrichment of Pb, Cu and Zn is an indication of anthropogenic influence to the sediment. The cave acts as a trap where a significant accumulation of different contaminants may occur.
