Özet
The role of phosphorus (P) in sediments in promoting marine eutrophication can be more efficiently evaluated by considering different P fractions instead of total P content. This paper presents the P distribution (total P, organic P, and fractions of inorganic P; loosely adsorbed P, and P bound to aluminium, P bound to calcium, and P bound to iron, as well as total inorganic P) in surface sediments collected in June 2015 at the NE Mediterranean Sea (due to extensive tourism is under anthropogenic pressure) using chemical (sequential extraction) fractionation techniques. A number of fractions were collected for each reagent for subsequent colorimetric determination using UV/Vis spectrometry and ICP-OES determination. The two methods show similar results for the P and the concentrations are in good agreement with the reference values. The results presented P-bound calcium as the major P fraction in the surface sediments collected, mainly due to the oversaturation of calcite and the co-precipitation of phosphate. Relative abundances of the remaining P fractions follow the order: Fe-P > Al-P > loosely bound P for coastal surface sediment.
