Abstract
The aim of the present study was to determine the concentrations of several potentially toxic elements (PTE) in the recent marine sediment of Makirina bay (central Adriatic), which could according to its organoleptic properties be used as a virgin material for medical treatment, wellness and relax purposes. Sediment samples were collected in June and July 2010 from six different sites in the central part of the bay. The range of measured elemental concentrations in analysed surficial sediment were: As (11-15,8 ppm), Cr (61,6 -109,5 ppm), Cu (19,4-54,2 ppm), Pb (16,8-29,6 ppm) and Zn (37-52 ppm). Sediment PTE pollution assessment was performed using contamination factor (CF), contamination degree (Cdeg) and pollution load index (PLI). The calculated environmental index values show a low to moderate contamination status of sediment. Future geochemical investigation on these sediments are necessary prior actual use in various therapeutic treatment.
