Abstract
A total of 32 surface sediment samples were collected from the East China Sea (ECS) to investigate the distribution of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments and evaluate their sources. The content of PAHs in the ECS surface sediments ranged from 2.3 ng/g to 57.8 ng/g. The source analysis revealed that the combustion of such fuels as petroleum is the main contribution source of PAHs in the ECS surface sediments, and oil spill is another important contribution source. The study also showed that the content of PAHs in the ECS surface sediments is low and does not cause adverse ecological risks.
期刊介绍：
Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
