摘要: Perfluorinated compounds (PFCs) have received much attention on their distributions in various matrixes of different areas globally, however, little is known about existences river sediments China. In this study, eight target PFCs including perfluorobutane sulfonate (PFBS), perfluorohexane (PFHxS), perfluorooctane (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic (PFNA), perfluorodecanoic (PFDA), perfluorododecanoic (PFDoA) and perfluorotetradecanoic (PFTA) were determined based upon the upper 10 cm surface sediment samples collected from eleven sites covering three main streams Daliao River system northeast China, which huge amount industrial domestic wastewater annually neighbouring areas. Analytical results indicated that total concentrations range 0.29–1.03 ng g−1 dry weight system. As dominant contaminants samples, PFOS PFOA ranged between
