| 摘 要： | 为探明胶州湾全氟烷基物质(perfluorinated alkyl substances,PFASs)的污染水平及特征,本研究于2018年4月在胶州湾近岸海域采集了海水、沉积物及菲律宾蛤仔样品,采用高效液相色谱-串联质谱法测定35种PFASs的含量.结果表明,海水中检出12种PFASs,PFASs总质量浓度(ΣPFASs)范围为21. 1～38. 0 ng·L-1,沉积物中检出10种PFASs,ΣPFASs含量(以干重计)范围为0. 459～1. 20μg·kg-1,菲律宾蛤仔中检出19种PFASs,ΣPFASs含量(以干重计)范围为15. 5～27. 5μg·kg-1;与国内外报道的其他地区相比,胶州湾ΣPFASs污染处于中等或偏高水平.全氟辛酸(perfluorooctanoic acid,PFOA)是胶州湾PFASs的首要污染因子,6∶2全氟辛烷二磷酸酯(6∶2 fluorotelomer phosphate diester,6∶2 di PAP)是海水及沉积物中检出的主要前驱物,全氟辛烷磺酰胺(perfluorooctanesulfonamide,PFOSA)是菲律宾蛤仔中检出的主要前驱物.此外,PFASs的沉积物-海水分配系数(Kd)、有机碳归一化分配系数(KOC)及生物累积因子(bioaccumulation factors,BAF)随碳链的增加而增加,而生物-沉积物累积因子(bioaccumulation factors between organism and sediment,BSAF)随碳链(C8～C13)的增加呈现下降趋势.
