- 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.
