Abstract
Residual PEGs in surface river water and sediments were measured at Nakdong River watershed. In this research considering hazards to human and environment, to understand the behavior of PFGs within inorganic materials while moving through river system, and evaluated inter-media distribution characteristics and the influence of river flow from Seonsan to estuary dike of Nakdong River. In surface water, the concentration of PEGs were detected the order as PFOA >PFNA>PFOS>PFHxS>PFOSA, and in sediments the order was PFOS>PFNA=PFOA>PFHxS=PFOSA. Carboxyl series, PFOA and PENA, showed high concentration in surface water, PFOS, PFHxS, and PFOSA were detected with low concentration. The concentration of PFOA and PFNA were relatively high in Nakdong River watershed and it is mainly due to the effects Geumho River.
