| 摘 要： | 洪泽湖是南水北调东线工程重要调蓄湖泊，为了解洪泽湖表层水中全氟和多氟烷基化合物(PFASs)的污染状况，通过超高效液相色谱串联四极杆质谱测定了湖区和入湖河流的表层水15种PFASs的含量，分析比较了不同区域水体中PFASs的浓度与组成，运用HCA法解析了不同污染来源，并应用HQ法对不同人群的健康风险进行评价.结果表明：(1)洪泽湖表层水中检出15种PFASs，ΣPFASs浓度为63.4～218.0 ng/L(中位值92.9 ng/L)，健康风险较低；(2)PFASs组分以短链为主，主要污染物为PFPeA，占60.8%；(3)PFASs在洪泽湖的空间分布呈现由南向北递减的趋势，洪泽湖湖心及过水通道区的PFASs浓度较高；(4)HCA方法表明，洪泽湖表层水中PFASs主要来自地表径流、橡胶品制造、食品包装和纸类表面处理的工业排放、纺织和金属电镀工业排放和生活污水.研究显示，洪泽湖表层水中广泛存在多种PFASs，以短链为主，健康风险对居民来说可接受.

| Abstract: | Hongze Lake is an important regulation and storage lake for the eastern route of the South-to-North Water Transfer Project. To understand the pollution status of per- and polyfluoroalkyl substances (PFASs) in the surface water of Hongze Lake, the concentrations of 15 kinds of PFASs in the surface water of the lake area and the rivers entering the lake were determined by ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry. The concentrations and composition of PFASs in different regions were analyzed and compared, and different pollution sources were analyzed by the HCA method. The HQ method was used to evaluate the health risk of different populations. The results showed that: (1) 15 kinds of PFASs were detected in the surface water of Hongze Lake, the concentration of ΣPFASs ranged from 63.4 to 218.0 ng/L (median value was 92.9 ng/L), indicating low health risk. (2) The PFAS components were mainly short chain, and the main pollutant was PFPeA, accounting for 60.8%. (3) The spatial distribution of PFASs in Hongze Lake showed a decreasing trend from south to north, and the concentration of PFASs in the center of Hongze Lake and the water passage area was higher. (4) The HCA method showed that the PFASs in the surface water of Hongze Lake mainly came from surface runoff, industrial discharges from rubber manufacturing, food packaging and paper surface treatment, textile and metal electroplating industrial discharges, and domestic sewage. The research showed that there are many types of PFASs in the surface water of Hongze Lake, mainly in short chain, and the health risk are acceptable to the residents. |
