The object of this study was to evaluate the combined toxic interactions of the perfluorooctanoic acid (PFOA) or perfluorooctane sulfonate (PFOS) with six heavy metals (Cu, Zn, Cr, Cd, Hg, and Pb). The individual and combined toxic effects were assessed using the Vibrio fischeri assay. In case of th...

과불화합물이란 무엇인가? | 과불화합물(Perfluorinated chemicals, PFCs)은 계면활성제 및 유화제로 사용되고 있는 신종 오염물질로 잔류성과 생물 축적성이 높아 논란이 되고 있다. 이중 perfluorooctanoic acid (PFOA)와 perfluorooctane sulfonate (PFOS)는 대표적인 과불화합물로써 그 자체도 생산되나 8:2 fluorotelomer alcohol 나 2-N-ethyl (perfluorooctanesulfonamido) ethanol 등의 과불화합물이 분해되어 생성되는 최종 분해산물로도 알려져 있다. | |
대표적인 과불화합물에는 무엇이 있는가? | 과불화합물(Perfluorinated chemicals, PFCs)은 계면활성제 및 유화제로 사용되고 있는 신종 오염물질로 잔류성과 생물 축적성이 높아 논란이 되고 있다. 이중 perfluorooctanoic acid (PFOA)와 perfluorooctane sulfonate (PFOS)는 대표적인 과불화합물로써 그 자체도 생산되나 8:2 fluorotelomer alcohol 나 2-N-ethyl (perfluorooctanesulfonamido) ethanol 등의 과불화합물이 분해되어 생성되는 최종 분해산물로도 알려져 있다.1) PFOA와 PFOS는 소수성(Hydrophobic) 및 소유성 (Oleophobic)의 특성을 지녀 방수나 방유처리가 필요한 옷, 가구, 카펫, 종이, 음식물 포장 등 다양한 생활용품의 표면처리제 및 샴푸, 광택제, 주방세척제 등의 계면활성제에 사용되고 있다. | |
perfluorooctanoic acid의 경우 전 세계의 하천수에서 얼마의 농도가 검출된 바 있는가? | PFOA의 경우 전 세계의 하천수에서 420 ng/L, PFOS는 157 ng/L의 농도가 검출된바 있으며, 국내에서 PFOA는 1.0~153 ng/L, PFOS는 0. |
