PFCs are group of fluorochemicals that have been produced and used for over 50 years for various purpose including soil/stain resistance and surfactant applications. These chemicals were degraded to Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) that were kinds of persistence metabolites. Previous studies showed that these chemicals can be accumulated in various environmental media. In this study, the concentration level of PFOS and PFOA were measured in 59 samples collected from 4 major river watersheds and 6 industrial complex areas in 2006 and 2007. Mean concentration of PFOS in water, sediment and soil were N.D.-1180.0 ng/L, N.D.-9.17 ng/g dry-wt. and N.D.-10.97 ng/g dry-wt. respectively. Mean concentrations of PFOA in water, sediment and soil were N.D.-13850.0 ng/L, N.D.-2.07 ng/g dry-wt. and N.D.-1.04 ng/g drywt., respectively. The concentration of PFOS in water samples were significant difference among river, industrial complex stream and waste water treatment effluent (p＜0.05). But PFOA were no significant difference among those samples. These results suggested that concentration of PFOS in water was direct effected by industrial complex activities. KCI Citation Count: 13
