Abstract

Seventy four marine organisms, which are common edible species and commercially important items in Korea, were sampled at the local fisheries markets and were analyzed for polycyclic aromatic hydrocarbons( PAHs) using gas chromatography coupled to mass spectrometer detector (GC/MSD). The levels of sixteen PAHs in selected organisms from Korean coasts were in the range of 0.45-224 ng/g dry weight. Bivalvia species showed the highest contents of PAHs, followed by crustacea, filipino venus and fish species. The residues of PAHs in marine organisms from the coastal environments of Korea were slightly low or relatively moderate in comparison with those in other countries. The predominant compositions of PAHs in fish species were the lower-molecular-weight two- and three-ring aromatic groups with similar patterns of those in seawater samples. The PAHs compositions of bivalvia, crustacea, cephalopoda and gastropoda species were dominated by threeand four-ring aromatics with intermediate PAHs patterns of sediments and seawater. However, PAHs compositions in Filipino venus, which live in muddy flat, were relatively comparable to those in marine sediments. The PAH profiles in various marine organisms according to exposure pathway were compared to abiotic samples such as marine sediments and seawater using factor analysis. The PAH profiles in each biotic or abiotic samples showed similar distributions. The result suggests that PAHs bioaccumulation pattern in organisms from the marine ecosystems was governed by a variety of factors including exposure circumstance, habitat, diet and metabolites.
