摘　　要：利用高效液相色谱与质谱联用技术(HPLC-MS/MS)对珠江三角洲同沙水库19个表层水样中PFOA和PFOS含量水平进行了分析,阐述了两种化合物在同沙水库中的污染现状.同沙水库表层水体中PFOA和PFOS浓度范围分别为2.15—26.70 ng·L^(-1)和nd—44.85 ng·L^(-1),其中库区中两种化合物的平均浓度要略高于入库支流.入库支流中PFOA和PFOS相对百分含量与库区相比,波动幅度较大,说明入库支流受到工业活动影响更明显.水库中一些点位PFOA和PFOS含量较为突出,其原因可能与周围的各种工业活动以及所处的特殊地理位置等因素有关.与国内外其他地区水体相比,同沙水库中PFOA和PFOS含量水平在国内处于较高水平,而在国际上处于相对较低的水平.As a class of emerging environmental persistent organic pollutants,perfluorooctanoic acid（PFOA） and perfluorooctane sulfonate（PFOS） have received much attention on their distributions in environment.Nineteen surface water samples were collected from Tongsha Reservoir of Pearl River Delta,South China in the present study.Concentrations of PFOA and PFOS were determined by high performance liquid chromatography-tandem mass spectrometry（HPLC-MS/MS） system.Theconcentrations of PFOA and PFOS ranged from 2.15—26.70 ng·L^（-1） and nd—44.85 ng·L^（-1）,respectively.The average concentrations of the PFOA and PFOS in the central area of Tongsha Reservoir were higher than those observed in its tributary.The relative abundance of PFOA and PFOS fluctuated significanthy in Tongsha Reservoir＇ s tributary.The results indicated that more industrial and agricultural activities had found in its tributary.The concentrations of PFOA and PFOS in TS3 and TS7 surface water samples were higher than those of other samples from Tongsha Reservoir.This might be due to their special locations,the various manufacturing and industrial activities.The concentrations of PFOA and PFOS in Tongsha Reservoir were higher than those of other regions in China,and lower than those of the regions in the world.
