Water, sediment, plankton, blood and liver of crucian carp (Carassius carassius) and mandarin fish (Siniperca cherzeri) samples from 5 freshwater ecosystems in 3 major rivers of Korea including Nam Han River, Nakdong River and Yeongsan River were collected together with medaka fish (Oryzias latipes) and water in their 5 natural habitats. The samples were analyzed to determine the occurrence and contamination level of perfluorinated compounds (PFCs). The mean total concentration of detected PFCs was in the ascending order of water, sediment, plankton, crucian carp and mandarin fish. Longchain PFCs (≥C8) was widely detected and occupied 99.32% of total PFCs concentration. Perfluorooctane sulfonate (PFOS) was the dominant PFC in most of the ecosystem components with a maximum concentration in water of 6.25 ng/L and in fish of 273 ng/g wet wt. The results also demonstrated that concentration of PFOS and total PFCs in blood of crucian carp and mandarin fish were higher than those in their liver. PFOS concentrations detected in water samples were lower than the water quality criteria values for aquatic organisms protection, which were reported in Giesy et al., 2010. A positive linear regression (r²=0.99, p<0.05) and a trophic magnification factor of 28.25 were observed between PFOS concentrations and trophic levels of collected biota. The mean bioconcentration factor (BCF) of PFOS were extended from 14,745±21,366 (in plankton) to 517,476±705,036 (in crucian carp blood). According to the method of Moermond et al., 2010 and the received BCF of sensitive medaka fish in this study, we suggested the MPCsp,water of 0.083 ng/L for PFOS in Korea freshwater ecosystems.
