摘要
///Sixteen polycyclic aromatic hydrocarbons ( PAHs) content was determined using GC-MS method from surface sediments collected across the western sea of Liaodong Peninsula. The distribution, source and ecological risk were discussed. The results show that the average concentration of PAHs was ( 173. 0 ± 20. 8) × 10 -9,indicating low to moderate contamination levels of PAHs compared with reported values for other coastal sediments in China and other countries. The relatively higher concentrations were observed in the middle-southern sea of study area, whereas relatively lower PAHs concentrations in the north. Source identification implied that PAHs in the north of the area mainly comes from petroleum combustion and spilled oil. PAHs in the middle-southern region were closely associated with grass, wood and coal burning. An ecological risk assessment of PAHs, based on the effect range-low ( ERL) quotients, suggested that adverse biological effects may take place in several sites ( Ne5,Ne9-Ne12,Ne15 and Ne18) caused by acenaphthene occasionally.
