The occurrence of 15 perfluoroalkyl substances (PFASs) in water, sediments, and fish from Songhua River and Yalu River in Jilin Province, Northeast China, during their spring flood period were investigated for the first time. The short-chain perfluorobutanoic acid was the dominant PFAS in the water with the mean concentrations of 10 ng L in Songhua River and 9.0 ng L in Yalu River, and also dominant in sediments with the mean concentrations of 2.0 and 1.8 ng g dry weight. Perfluorodecane sulfonate was the predominant compound in fish. The detected frequencies and concentrations of perfluorooctane sulfonate and perfluorooctanoic acid were very low in the water, sediments, and fish. Low detected frequencies and concentrations of long-chain PFASs led to relative low sediment-water partition coefficients and bioaccumulation factors. The concentration levels of PFASs in the two rivers were lower than those in other major rivers in China.
首次对中国东北吉林省松花江和鸭绿江春汛期间水体、沉积物及鱼类中的15种全氟烷基物质（PFASs）进行了调查。短链全氟丁酸是水体中主要的PFAS，在松花江中的平均浓度为10 ng/L，在鸭绿江中的平均浓度为9.0 ng/L，在沉积物中也占主导地位，平均浓度分别为2.0和1.8 ng/g干重。全氟癸烷磺酸是鱼类中的主要化合物。全氟辛烷磺酸和全氟辛酸在水体、沉积物和鱼类中的检出频率和浓度很低。长链PFASs的低检出频率和浓度导致沉积物-水分配系数和生物累积因子相对较低。两条河流中PFASs的浓度水平低于中国其他主要河流。
