主 题:polycyclic aromatic hydrocarbons Liaodong Bay source apportionment ecological risk assessment,sediment
摘 要:The sources and ecological risk from sixteen polycyclic aromatic hydrocarbons in surface sediment in the Liaodong Bay were investigated from 2014 to *** total concentrations of PAHs ranged from 88.5 to 347.1 ng/g,and the high value occurred in the central region of the Liaodong *** analysis identified two site clusters representing the coastal region affected by land-based pollution and the central region of the Liaodong *** component analysis-multiple linear regression and diagnostic ratios suggested that PAHs contaminants originated from a mixture of combustion and petroleum sources,and the major was combustion *** on sediment quality guideline,naphthalene,acenaphthylene,acenaphthene,phenanthrene and dibenz[a,h]anthracene may occasionally cause adverse biological effects in some *** toxic equivalent concentrations of carcinogenic PAHs indicated low carcinogenic risk for the Liaodong *** ecological risk and toxic pollution levels of PAHs were higher in the central region than in the coastal region along the Liaodong Bay.
