Sažetak
In this paper we determined the concentrations of organic phosphorus (OP) and inorganic P species: P in biogenic apatite (P-FD), P adsorbed onto iron- oxy/hydroxides (P-Fe), P in authigenic apatite (P- AUT) and P in detrital apatite (P-DET) in sediments from two tuna farms in the middle Adriatic related to control site with no fish farm inside. Regarding the previous analyses of phosphorus in middle Adriatic, additional extraction step in determination of OP was applied. Vertical profiles of P forms in sediment cores were also examined. To identify geochemical changes in below-cage sediments in relation to „unaffected site“, we also examined interactions between physico-chemical characteristics of sediment (sediment type, carbonates, organic matter content, organic carbon, total nitrogen and redox potential) and P forms.
