Perfluorinated compounds (PFCs) as environmental pollutants are an important environmental issue. However, little is known on the PFCs monitoring of sea waters around estuaries on the East and West Coasts of Korea. This study shows the monitoring results of PFCs in sea waters in these Coasts. Among 10 PFCs selected in this study, concentrations of perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), perfluorobutane sulfonate (PFBS), and perfluorohexane sulfonate (PFHxS) in the East Coast were 9.6-50.7 ng/L (total mean ± standard deviation: 26.14 ± 12.66 ng/L), 13.79-44.58 ng/L (27.95 ± 11.41 ng/L), limit of quantification (LOQ)-2.6 ng/L (0.96 ± 1.15 ng/L), and 2.95-11.05 ng/L (4.25 ± 2.57 ng/L), respectively. In the West Coast, concentrations of PFOS, PFOA, PFBS, and PFHxS were 27.66-51.71 ng/L (36.27 ± 7.79 ng/L), 8.97-22.53 ng/L (14.47 ± 4.25 ng/L), LOQ-2.27 ng/L (1.63 ± 0.93 ng/L), and 3.0-7.66 ng/L (4.27 ± 1.49 ng/L), respectly. Other PFCs were below LOQ. The result of this study provides the distribution pattern of PFCs for assessing environmental pollution in two coastal areas of Korea..
