Per- and polyfluoroalkyl substances (PFASs) have attracted great concern because of their great recalcitrant nature and harmful environmental health effects. Eight PFASs in wastewater from craft villages and industrial environments of Vietnam were analyzed using liquid chromatography triple quadrupole mass spectrometry (LC-MS/MS) with negative electrospray ionization interface. For analysis of PFASs, percent recoveries ranged from 87 to 112, and MQL varied from 0.19 ng/L to 0.49 ng/L. Treated wastewater samples from eight metal-plating and eight textile-dyeing factories were collected for analysis of PFASs. Concentrations of PFOS in wastewater samples obtained from metal-plating factories with decorative plating stage were found at a range of 0.73–18.91 ng/L. For textile-dyeing factories, PFOA and/or PFHxA, which were present in all effluent wastewater samples, varied from 0.37 to 15.96 ng/L and 1.07 to 43.58 ng/L, respectively. Sixty surface water samples in four locations of the textile dyeing craft villages, a recycling plastic village, a paper recycling village, and 10 river water samples in the control area (a rural area without specific waste sources) were collected and analyzed for PFASs. The total concentrations of eight PFASs in surface water samples of craft villages ranged from 0.83 to 58.2 ng/L, which were significantly higher than those in the control area. PFOA, PFHxA, and PFOS are the three most dominant congeners in wastewater taken from craft villages with the highest concentrations of 27.4, 23.8, and 7.36 ng/L, respectively. The environmental risks posed by PFASs in surface water from craft villages were mainly in a range of extremely low to low level, particularly a few points have high ecological risks of PFDoA.

越南工艺村和工业环境中全氟和多氟烷基物质的测定

全氟烷基物质和多氟烷基物质(PFAS)由于其顽强的顽固性和有害的环境健康影响而备受关注。使用带有负电喷雾电离界面的液相色谱三重四极杆质谱(LC-MS / MS)对越南工艺村和工业环境中的废水中的八种全氟辛烷磺酸进行了分析。对于PFAS的分析,回收率百分比从87到112,MQL从0.19 ng / L到0.49 ng / L不等。收集了来自八家金属电镀厂和八家纺织印染厂的处理过的废水样品,用于分析PFAS。从具有装饰性电镀阶段的金属电镀工厂获得的废水样品中的全氟辛烷磺酸浓度范围为0.73–18.91 ng / L。对于纺织染厂,PFOA和/或PFHxA,所有废水样本中的污染物含量分别为0.37至15.96 ng / L和1.07至43.58 ng / L。在控制区(一个没有特定废物源的农村地区)的纺织染色工艺村,一个回收塑料村,一个造纸回收村和四个地方的60个地点收集了60个地表水样品,并进行了PFAS分析。工艺村地表水样品中的八种全氟辛烷磺酸的总浓度为0.83至58.2 ng / L,显着高于对照地区。PFOA,PFHxA和PFOS是取自工艺村的废水中三个最主要的同类物,分别为27.4、23.8和7.36 ng / L的最高浓度。
