【摘要】:全氟化合物(PFCs)作為一類新型的有機(jī)污染物已被持續(xù)關(guān)注.本文以雙臺子河口為研究對象,采用固相萃取(SPE)前處理與高效液相色譜串聯(lián)質(zhì)譜聯(lián)用(HPLC-MS/MS)相結(jié)合的方法分析水樣中包含短鏈全氟丁酸(PFBA)、全氟丁基磺酸(PFBS)、全氟戊酸(PFPe A)在內(nèi)的15種主要PFCs的含量水平,并對全氟辛烷磺酸(PFOS)與全氟辛酸(PFOA)的生態(tài)風(fēng)險(xiǎn)及人群健康風(fēng)險(xiǎn)進(jìn)行評價(jià).結(jié)果表明,雙臺子河口水體存在PFCs污染,∑PFCs介于43.40~157.71 ng·L~(-1)之間,PFBA和PFPe A是水體中的主要污染物.此外,采用風(fēng)險(xiǎn)商法粗略評估得到PFOS與PFOA的風(fēng)險(xiǎn)值均遠(yuǎn)低于參考值,風(fēng)險(xiǎn)較小.
[Abstract]:Perfluorinated compounds (PFCs) as a new type of organic pollutants has been sustained attention. In this paper, the mouth of the Shuangtaizi River as the research object, using solid phase extraction (SPE) pretreatment and high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) method combined with the analysis of samples containing short chain perfluorobutyric acid (PFBA), total fluorine butyl sulfonic acid (PFBS), perfluorinated acid (PFPe A) levels of 15 major PFCs, and perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) of the ecological risk and population health risk assessment. The results show that the PFCs pollution in Shuangtaizi estuary, the total PFCs from 43.40~157.71 ng L~ (-1), PFBA and PFPe A are the main pollutants in water. In addition, the risk assessment of PFOS and PFOA are roughly commercial values were much lower than the reference value, the risk is small.
