英文摘要Perfluoroalkyl and polyfluoroalkyl substances(PFASs)are a group of manmade chemicals and are ubiquitously detected in aquatic environments.China is a major producer and consumer of PFASs.In this study,we investigated the occurrence and characteristics of PFASs in the surface sediments from three fluorine industrial parks in North China,the Xihe River in Liaoning Province(Fuxin Section),the Xiaoqing River in Shandong Province(Zibo Section),and the Yangtze River in Jiangsu Province(Changshu Section),using the UPLC/MS-MS method.The total concentration of PFASs(Sigma PFASs)in surface sediments of the Xihe River ranged from 15.8 to 2 770 ng·g~(-1),and PFTeDA and HFPO-DA were the dominant pollutants.In the surface sediments of the Xiaoqing River,Sigma PFASs ranged from 12.2 to 7 853 ng·g~(-1),and PFOA and HFPO-DA were the dominant pollutants.In the surface sediments of the Yangtze river,Sigma PFASs ranged from 9.20 to 35.9 ng·g~(-1),and PFTeDA and 6∶ 2 FTS were the main pollutants.Sewage discharge from the industrial parks(point source pollution)was the main source of PFASs in three regions in this study.The PFAS content and composition in three regions varied significantly depending on the production capacity and industry type.There was no significant correlation between the content of PFASs and its components and the particle size and TOC of the sediments.The correlations between the components of PFASs indicated that the enrichment process of PFASs in sediments was impacted by various factors.
中文摘要采用超高效液相色谱/质谱联用(UPLC/MS-MS)分析了我国重要的氟化物工业园区周边河流辽宁细河(阜新段)、山东小清河(淄博段)和长江(江苏常熟段)表层沉积物中全(多)氟烷基化合物(PFASs)的污染状况.细河表层沉积物中,PFASs含量范围(以干重计,下同)为15.8~ 2770ng·g~(-1),全氟丁烷磺酸(PFBS)和六氟环氧丙烷二聚酸(HFPO-DA)是主要污染物;小清河表层沉积物中,PFASs含量为12.2~ 7853ng·g~(-1),全氟烷基辛酸(PFOA)和HFPO-DA为主要污染物;长江表层沉积物中,PFASs含量为9.20~ 35.9ng·g~(-1),全氟十四酸(PFTeDA)和6∶ 2氟调磺酸(6∶ 2FTS)为主要污染物.工业园区废水排放(点源污染)是本研究中3个区域PFASs的主要来源.3个区域PFASs含量及组成差异明显,与工业园区生产规模和产业类型有关.PFASs含量及各组分含量与TOC、沉积物粒径没有显著相关性,PFASs各组分间相关性也有差异,说明PFASs在沉积物中的富集过程与多种因素有关.
