Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are emerging pollutants in agricultural product, and the residual patterns and the uptake potentials were only studied on several crops, not on rice. The residue level and bioconcentration factor (BCF) of PFOA and PFOS were inves...

과불소화합물이란 무엇인가? | 과불소화합물(perfluorinated compounds, PFCs)은 1950년대부터 생산되어 금속, 제지, 섬유, 전자산업 등에 광범위한 용도로 사용되고 있는 물질이다[1, 2]. 이로 인해, 과불소화합물의 환경매체 중 잔류 농도는 ng kg−1 수준 이상으로 꾸준히 보고되고 있고, 이들 중 긴 탄소사슬을 갖는 물질은 난분해성과 생물농축성, 열안정성 및 높은 수용성으로 인해 인체 및 환경 위해성이 끊임없이 제기되고 있다[2,3,4]. | |
과불소화합물의 문제점은 무엇인가? | 과불소화합물(perfluorinated compounds, PFCs)은 1950년대부터 생산되어 금속, 제지, 섬유, 전자산업 등에 광범위한 용도로 사용되고 있는 물질이다[1, 2]. 이로 인해, 과불소화합물의 환경매체 중 잔류 농도는 ng kg−1 수준 이상으로 꾸준히 보고되고 있고, 이들 중 긴 탄소사슬을 갖는 물질은 난분해성과 생물농축성, 열안정성 및 높은 수용성으로 인해 인체 및 환경 위해성이 끊임없이 제기되고 있다[2,3,4]. 특히, perfluorooctanoic acid (PFOA)와 perfluorooctane sulfonic acid (PFOS)는 수계와 토양에서 가장 빈번히 검출되는 PFCs 물질로 알려져 있으며, 이들 중 PFOS 및 유도체들은 Stockholm Convention에서 잔류성유 기오염물질(persistent organic pollutants, POPs)로 지정되어 있다[3,5]. | |
PFOS 및 유도체들이 잔류성 유기오염물질임에 따라, 발생하는 문제는 무엇인가? | 특히, perfluorooctanoic acid (PFOA)와 perfluorooctane sulfonic acid (PFOS)는 수계와 토양에서 가장 빈번히 검출되는 PFCs 물질로 알려져 있으며, 이들 중 PFOS 및 유도체들은 Stockholm Convention에서 잔류성유 기오염물질(persistent organic pollutants, POPs)로 지정되어 있다[3,5]. 따라서, 이들 PFCs의 환경 잔류로 인한 생태계 먹이사슬 내 오염과 오염 식품섭취로 인한 인체 위해성 발생가능성은 꾸준히 문제제기되고 있다. |
