Sažetak
Polycyclic aromatic compounds (PAC) were investigated in 29 sediment samples from the Eastern Adriatic Sea (Mediterranean Sea). PAC concentrations ranged from 14, 98 to 23970, 92 µg kg-1. The highest PAC levels were determined in sediments from the Sibenik Bay and the lowest PAC levels were determined in open sea sediments. Unsubstituted PACs predominated in sediments from the Sibenik Bay and the Coastal area, while methylsubstituted PACs were dominant in sediments from the open sea area and the Kastela Bay. Benzofluorantenes were dominant PAC compounds in most of investigated samples. The pyrogenic origin of PACs was determined for each station in the Sibenik Bay and the majority of stations in the Coastal area, while in the open sea area PAC originated from petrogenic sources. Equal contribution of pyrogenic and petrogenic sources was determined in the Kastela Bay. Positive Matrix Factorization (PMF) provided detailed and accurate information on the PACs’ origin that can be applied in coastal management purposes. A high level of pollution was determined at K3, P3 and P9, whereas moderate pollution was determined in other investigated stations of the Kastela Bay and the Coastal area. A low level of pollution was determined for each station in the open sea area. Due to a very high level of pollution, determined at each station of the Sibenik Bay, the entire Sibenik Bay can be considered a HOT SPOT area.
