  • Title: Polycyclic aromatic hydrocarbons in marine sediments from the Rijeka Bay area, Northern Adriatic, Croatia, 1998-2006.
    Author: Alebic-Juretic A.
    Journal: Mar Pollut Bull; 2011 Apr; 62(4):863-9. PubMed ID: 21414638.
    Abstract:
    The first analyses of PAHs in marine sediments within Rijeka Bay started in 1998 at three sampling sites offshore from the petroleum refinery facilities and were extended in 1999 to three more sampling points in front of the repair shipyard within the same east industrial zone. The small Svezanj cove, lying between the shipyard and the petroleum refinery was chosen as the reference point. The concentrations of PAHs were considerably higher in the shipyard environment (average: 3009-6314 μg kg⁻¹ d.w.) in comparison to the petroleum refinery area (average: 279-919 μg kg⁻¹ d.w.), while the PAHs load at reference point was close to the latter level (average: 717 μg kg⁻¹ d.w.). The Phe/Anth and Flo/Py ratios indicate the dominant pyrogenic sources, except for the results from 1999 to 2000 with dominant petrogenic origin at some sites. A declining trend of total PAHs, and consequently toxicity indices was observed at all sites.
