Concentrations of perfluorinated compounds (PFCs) in water samples from Anseong and Gyeongan stream were measured using an LC-MS/MS system. The average perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) concentrations of samples collected from Anseong stream were 43.4 ng/L, 15.0 ng/L, 14.5 ng/L and 3.5 ng/L, respectively. In the case of Gyeongan stream, the average concentration of PFOS, PFOA, PFHxS and PFNA were 15.5 ng/L, 8.3ng/L, 5.4 ng/L and 1.5 ng/L, respectively. From the result, PFOS was found the dominant PFCs in these streams. The PFCs detected from the streams were correlated with DOC concentration, UV/vis factor and Fluorescence properties of water samples. In general, PFCs concentration had positive correlations with DOC concentration,A250/365 and A465 and synchronous Fluorescence indexes (Protein-Like Fluorescence, Fulvic-Like Fluorescence, Humic-Like Fluorescence). However, PFCs were negatively correlated with SR. This result showed that concentration of PFCs could be significantly influenced by the aromaticity and molecular weight of organic compounds in water samples. KCI Citation Count: 0
