| 摘 要： | 为调查巢湖水体中PFOS污染状况,应用超高效液谱串联质谱(UPLC-MS-MS)检测巢湖水中PFOS。检测结果显示,主要支流入湖口、沿岸重要工农业生产基地和旅游区涉及的巢湖水域中PFOS大部分处在(8.4±1.2)ng.L-1和(106±10.2)ng.L-1之间,最高达(400±51)ng.L-1。比较国内外相近水体,结果表明巢湖水体PFOS处于相对偏高的水平,分析其来源主要是重要支流中工农业生产和生活污水。对巢湖水中PFOS饮用风险的初步评估结果表明,日常饮用巢湖水还不足以导致人体过度暴露于PFOS污染,但可以通过生物富集对处于食物链顶端鸟类产生影响,应当引起重视。

| Abstract: | The PFOS(perluorooctane sultonic acid)was determined using the UPLC-MS-MS after sampling the water in order to investigate the PFOS’ pollution in Chaohu Lake.Most PFOS concentrations in Chaohu Loke ranged from(8.4±1.2) ng?L-1 to(106±10.2) ng?L-1.The highest one is(400±51) ng?L-1.It was little higher compared with that in the similar aqueous.The pollution resources may be the input of industrial and the munici-pal waster water into the lake.The primary assessment of drinking risk indicated that it is lest risk for people’s extra exposition to the PFOS if only drinking the water.However,it may affect the birds at the top of the food-chain through the bioaccumulation. |
