摘要
检测了大连湾沉积物中16种PAHs的含量,利用TEQ值法评价表层沉积物中PAHs生态风险,并利用组成特征法进行来源解析。结果表明:大连湾表层沉积物中PAHs均主要来自于煤炭等化石燃料燃烧,而受到石油输入影响较小。大部分采样点TEQ值远远超出无观察效应值,表明大连湾内大部分采样点可能已受到PAHs的影响,需引起相关部门的注意。
The content of polycyclic aromatic hydrocarbons （PAHs） in the surface sediments of Dalian Bay was investigated in this paper. The method of composition characteristics was used to identify the main source of PAHs and TEQ value method was used to assess the ecological risk of PAHs in the surface sediment. The results showed that the main source of PAHs was identified from the petrolic combustion and coal burning,not the petroleum. The TEQ values in most sample sites were over not observed,it showed that PAH in the sediment of Dalian Bay had the stronger ecological risk and need more attention.
