摘  要：
利用高效液相色谱与质谱联用技术(LC-MS-MS)检测了东江流域31个表层沉积物样品中全氟辛酸(PFOA)和全氟辛烷磺酸(PFOS)的含量水平,并初步分析了上述两种污染物在东江流域的分布规律。东江流域表层沉积物中PFOA和PFOS含量范围分别为0.01～1.25ng·g-1dw和0.01～2.93ng·g-1dw。东江流域沉积物受PFCs污染程度不同,顺序依次为东江上游<东江中下游<东江河口区。研究显示:PFOS的相对百分含量范围是62.0%～77.9%,高于PFOA的相对百分含量;PFOS和PFOA呈显著正相关关系(P<0.05),说明东江流域表层沉积物中PFOS和PFOA可能具有相似来源。与世界其他地区沉积物中PFOA和PFOS的含量水平相比,东江流域表层沉积物中PFOA和PFOS的含量处于较低水平。

摘  要：
Perfluorinated compounds(PFCs)have received much attention on their distributions in various matrixes including water bodies,biota,and serum of populations in recent years,however,little is known about their existences in river sediments of China.In the study,surface sediment samples were collected from 31 sites in the Dongjiang River across Guangdong Province,South China.Two target PFCs including perfluorooctanoic acid(PFOA)and perfluorooctane sulfonate(PFOS)in surface sediments samples were determined by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)system,illustrating the distribution of PFOA and PFOS in surface sediments from Dongjiang River,South China.Analytical results indicated that the concentrations of PFOA and PFOS were determined in the range of 0.01～1.25 ng·g-1 dry weight and 0.01～2.93 ng·g-1 dry weight in surface sediments,respectively.The order of PFCs concentrations in sediments from Dongjiang River was as follow:upstream area
