Summary:To determine the concentrations of selected 10 perfluorinated compounds (PFCs), a field study was conducted in the water body of Yeongsan River Water System. Raw water samples were collected in the spring and the fall, respectively, which included 18 sampling sites. Collected samples were equally mixed and then served as an analytical sample. The concentration of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) were in range of 20.80-92.0 ng/L and ND-28.40 ng/L respectively. Perfluorononanoate (PFNA) and perfluorohexanesulfonate (PFHxS) were ranged from ND to 42.20 ng/L and from ND to 11.47 ng/L. The detection frequencies of other PFCs selected in this study were very sparse at very low concentrations, except for PFOS, PFOA, PFNA and PFHxS. PFOS was higher detection frequency and concentration in both spring and fall, PFOA and PFNA were in spring, and PFHxS was in fall. As a result, the observed concentrations of PFCs in the downtown water area of Gwangju, located in the wastewater treatment plants, were relatively higher than other sampling points. 이 연구는 영산강 수계 중 수체를 대상으로 10종의 과불화 화합물 (perfluorinated compounds, PFCs)로 인한 오염실태를 파악하기 위한 모니터링을 수행 하였다. 시료채취는 영산강 전수계에 걸쳐 있는 총 18지점에서 이루어졌고, 5-6월인 봄철과 10월인 가을철 두 번에 걸쳐 시료가 채취되었다. 10종의 PFCs 오염물을 대상물질로 하여 분석한 결과, 물 시료 중 농도는 PFOS (perfluorooctanesulfonate)가 20.8-92.0 ng/L, PFOA (perfluorooctanoate)가 method detection limit (MDL)-28.40 ng/L로 검출되었으며 PFNA (Perfluorononanoate)가 MDL-42.20 ng/L, PFHxS (perfluorohexanesulfonate)가 MDL-11.47 ng/L로 나타났다. PFOS는 봄과 가을철 모두에서 검출빈도와 그 농도가 높았고, PFOA와 PFNA는 대체로 봄철이, PFHxS의 경우는 가을철에 검출빈도와 농도가 높은 것으로 조사되었다. 하지만 상기 4종을 제외한 다른 PFCs 화학종은 검출빈도가 낮고 매우 낮은 농도인 것으로 나타났다. 하 폐수처리장이 위치한 광주의 도심지역 수계지역의 수체 시료에서 검출된 PFCs의 농도는 타 영산강 수계내 수체 시료에 비해 상대적으로 높은 것으로 나타났다.
