초록
과불화 화합물(perfluorinated compounds, PFCs)은 열과 산성, 염기 등과 같은 화학적 조건에 높은 안정성을 갖고 있을 뿐만 아니라 발수성, 발유성, 방오성과 제품 친화적인 특징 때문에 다양한 산업소재로 활용되고 있으며, 근래에 이르러서는 대규모로 생산되고 있는 산업제품이다. 그러나 난분해성으로 인하여 환경 내에 잔류하여 전세계적으로 널리 분포하고 있을 뿐만 아니라 인체나 동식물에 이르는생물체에 이르기까지 오염되어 분포하고 있다. 또한 인체를 비롯한 생물체에 장기적으로 축적될 시 암등을 유발할 가능성이 있다고 보고됨에 따라 이에 대한 관심이 증가하고 있다. 최근 스톡홀름 협약에서과불화 화합물을 새로운 환경지속성오염물질(persistent organic pollutants, POPs)로 규정함에 따라 이에 대한 분석법의 중요성이 대두되고 있다. 본 연구에서는 다양한 환경 및 생체 시료 내에서 과불화 화합물의분석법에 대한 연구의 중요성 및 문제점과 더불어 최근 연구 동향을 소개하였다.
Abstract
Perfluorinated compounds have characteristics of resistance to heat, acidic, basic conditions and also resist water, oil, grease, pollutant. Futhermore they are used by various industrial material, nowadays, they produced in large scale for indutrial and commercial areas. However, they also resist metabolizing and degrading in environmental system (plant, animal, even human body). Moreover, in animal's bodies, PFCs can be accumulated in organ (eg;liver) and lead to liver cell necrosis even oncogenesis. Perfluorinated compounds are newly registered as new persistent organic pollutants (POPs) on Stockholm convention in 2009. Therefore necessity for analytical methodology for determination of PFCs in various environmental samples is even more increased. This study discussed sample preparation and instrumental conditions for the analysis of PFCs in environmental and biota samples.
