摘要:
采用在线固相萃取-超高效液相色谱串联质谱法对太湖及其主要入湖河道中全氟辛酸（PFOA）和全氟辛烷磺酸（PFOS）的来源及分布特征进行研究，结果表明，PFOA和PFOS在太湖及其入湖河道中均有检出，浓度分别为4.3~53.5、6.9~125.0 ng/L；受22条入湖河道影响，太湖中全氟化合物（PFCs）污染总体呈由南北向中部递减的趋势；江苏省4个地市中入湖河道的PFCs污染相对严重，主要由于其均为重工业城市，氟化工及含氟产品的使用更加密集；与国内外湖泊、河流相比，太湖及其入湖河道中PFOA和PFOS污染整体处于较高水平。
Abstract:
This paper investigated the sources and distribution characteristics of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in Taihu Lake and its main inlet channels by on-line solid phase extraction, ultra-high performance liquid chromatography tandem mass spectrometry. PFOA and PFOS were detected in Taihu Lake and its inlet channels, with concentrations ranging from 4.3 ng/L to 53.5 ng/L and 6.9 ng/L to 125.0 ng/L, respectively. The pollution of perfluorinated compounds (PFCs) in Taihu Lake showed a decreasing trend from the north and south to the middle due to the influence of 22 river channels into Taihu Lake. The pollution of PFCs in river channels leading to the lake was relatively serious in four cities of Jiangsu Province, mainly because they were all heavy industrial cities and the use of fluorine chemicals and fluorine-containing products was more intensive. Compared with lakes and rivers at home and abroad, the pollution of PFOA and PFOS in Taihu Lake and its inlet channels was at a relatively high level.
