摘要： We investigated distribution, sources, and potential risks of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments from the largest mariculture base in the eastern part of the province of Guangdong in southern China. Total concentrations of Sigma PAHs were 29.38-815.46 ng/g (dry weight), with a mean of 421.48 ng/g. The composition of PAHs was characterized by an abundance of low molecular weight PAHs (2-3 benzenoid ring), and Phenanthrene (PHE), Anthracene (AN) and Fluoranthene (FA) were the predominant constituents. PAHs in this area appear to have mainly originated from petroleum sources and the combustion of grass, wood, and coal. PAHs in surface sediments of Zhelin Bay had a 9% incidence of causing adverse biological effects on aquatic organisms, according to the mean effects range-median quotient. (C) 2016 Elsevier Ltd.
