摘  要：
采用现场采样及室内高效液相色谱分析测试的方法,探讨了微山湖表层沉积物中多环芳烃(PAHs)的分布,并进行了风险评价。结果表明,微山湖表层沉积物中16种优控PAHs的总量范围在324.93～1576.65ng.g-(1干重)之间,平均值为699.01ng.g-1,属中等污染水平,沉积物中的多环芳烃主要来源于煤炭、木材及石油的不完全燃烧。利用沉积物质量基准法(SQGs)、沉积物质量标准法分别对微山湖沉积物中多环芳烃的风险评价表明,严重的多环芳烃生态风险在微山湖沉积物中不存在,负面生物毒性效应则会偶尔发生,风险主要来源于低环的多环芳烃,以芴(Flu)和苊(Ace)为主。

摘  要：
As an important storage lake of The Grand Cana(lNorthern Section of Jiangsu Province),the water quality of Weishan Lake will significantly affect the efficiency of Water Transfer Project from South to North.In order to define the levels of PAHs in Weishan Lake,ten sediment samples were collected from the lake in Weishan County,China,in 2009.In this study,16 polycyclic aromatic hydrocarbons(PAHs)were quantitatively determined by HPLC.The concentration(dry weight)of PAHs varied from 324.93 ng.g-1 to 1 576.65 ng.g-1,with average 699.01 ng.g-1,which was in moderate level compared with other lakes.A significant difference in the PAHs pollution was observed at different regions.There were three regions(Weishan island,Erji dam and Shizi-xuehe river estuary)with the severer PAHs pollution in Weishan Lake,and the distribution of PAHs was closely related with human activities.The indexes of source identification indicated the main source of PAHs in the samples was combustion source,which included coal,oil and wood inadequate combustion.The ecological risk of surface sediment in Weishan Lake was assessed with the methods of sediment quality guidelines(SQGs)and sediment quality standards(SQSs).The results showed that the concentration levels of PAHs in the study area had not caused the marked negative influence on organism.However Flu and Ace compounds were present in excess of the lower ERL,and biological effects might exist;The adverse biological toxicity effect might occasionally happen in Weishan Lake.
