  • 摘要: 采用Oasis®-WAX-SPE柱富集,高效液相色谱/电喷雾负离子源串联质谱(HPLC/negative ESI/MS/MS)对常熟氟化学工业园区地表河水样品和水生动物样品(乙腈萃取物)中的全氟及多氟化合物(PFASs)进行了测定,分别检测出8种和14种PFASs.园区河水中总PFASs浓度范围为91.0—9374.9 ng·L-1,为国内已有报道中最高;PFOA和PFPrA是河水样品中含量最高的两种PFASs,且在不同水样中均可占到总PFASs的73%以上,未检出PFOS;生物样品中总PFASs浓度范围为12.93—394.77 ng·g-1ww(湿重),PFOA、PFOS和PFPrA为主要PFASs;与园区所在城市的鱼类等样品相比较,采自氟化学工业园区的鱼类体内富集了更多的PFAS.研究结果表明,常熟氟化学工业园区地表水环境PFOA和PFPrA污染较重,为目前国内最高水平;在园区河水和生物体内检测出高浓度的PFPrA,说明氟化学工业园区内部分工厂可能已使用短链氟化物替代PFOA和PFOS,在今后的研究中对PFPrA等短链全氟化合物的监测应给予更多关注.
    Abstract: Perfluoroalkyl and Polyfluoroalkyl substances (PFASs) were quantified in river water and biological samples (acetonitrile extraction) collected from Jiangsu Hi-tech Fluorochemical Industry Park in Changshu by HPLC/negative ESI/MS/MS. 8 PFASs and 14 PFASs were detected in water and biological samples, respectively. The concentrations of total PFASs ranged from 91.0—9374.9 ng·L-1 in river water samples and from 12.93 to 394.77ng·g-1wet weight in fish samples, which exceeded the highest level ever reported in China. Perfluorooctanoate acid (PFOA) and pentafluoropropionic acid (PFPrA) were predominant,and both contributed to more than 73% of the total PFASs in different water samples, while perfluorooctanesulfonic acid (PFOS) were not detected in all water samples. In biological samples, PFOA, PFOS and PFPrA are dominant, and higher concentrations of PFASs were found in fishes collected from the industry park than those from Changshu city. These results indicated that the pollution of PFOA and PFPrA in the surface water environment of the industry park of fluorine chemistry in Changshu has reached the highest level in China. Especially, high concentrations of PFPrA in water and biological samples suggested that the replacement of PFOS and PFOA by short-chain fluorochemicals has been generalized by some manufacturers in Jiangsu Hi-tech Fluorochemical Industry Park. Quantification of short-chain PFASs is needed in future work to draw better conclusions about their environmental fates.
