| Abstract: |
| 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 |
