Abstract
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants formed by either thermal alteration of buried organic matter or incomplete combustion of organic matter. PAHs are detectable almost everywhere in the environment, including seawater, sediment/soil, air, and organismal tissues. Human utilization of petroleum products and combustion of organic matter are the major sources of anthropogenic PAHs in the environment. The hydrophobicity, low volatilities and recalcitrance toward degradation of high molecular weight PAHs lead to their persistence in the environment. PAHs have been shown to have toxicological effects on organisms. PAHs in some fossil fuel products, such as benzo(a)pyrene, are known to cause cancer, skin disease and hormone malfunction. Molecular compositions of PAHs were analyzed in sediment and seawater collected in the southern Yellow Sea. Total concentrations of 16 EPA priority PAHs ranged from 10.7 to 27.7 ng/g dry wt. in sediment. Naphthalene was the most abundant PAH consisting more than 50 % of total PAHs, followed by phenanthrene, fluoranthene, pyrene, chrysene and benzo[b]fluoranthene. Source recognition indexes indicated that the PAHs in the sediment were pyrogenic in origin showing close similarity with urban dust PAHs. High volume (about 140 liters) of seawater sample was also analyzed for PAHs in particulate and dissolved phases. Total PAHs ranged from 7.6 to 90.5 ng/L in dissolved phase and from 0.2 to 1.4 ng/L in particulate phase. PAH concentrations in dissolved phase were about 5 to 300 times higher than those in particulate phase. High PAH concentrations appear to be related with the occurrence of low-salinity water patch observed in the study site. PAH molecular compositions in seawater were compared with those of possible sources and the origins of the PAHs were discussed.
