초록

무단 폐기물 투기로 인해 토양, 지하수, 하천 등 환경오염이 심각해지고 있다. 본 연구에서는 J시에서 발생된 무단 투기 유류를 분석함으로써 어떤 유종인지를 분석하였다. 물, 고형불순물, 유류 혼합물 형태를 전처리하여 균질한 유류성분을 얻은 뒤, 물성분석, 원소분석, 및 가스크로마토그래피를 이용해 분석한 결과, 11.8%의 산소함량, $-6^{\circ}C$의 유동점, 크로마토그램의 패턴 결과 식물성기름으로 판단하였다. 또한 어떤 식물성 기름인지 알기 위해 HPLC를 이용해 구성성분을 분석한 결과, LLO, OOL, POL이 높은 비율로 분석되어졌으며, 이는 대두유가 주성분이면서 다른 식물성기름의 혼합형태인 폐유로 최종 판단하였다. 본 연구를 통해 향후, 불법 투기되는 유류에 대한 유종 구분 및 오염원인자 판단을 위해 활용 가능할 것으로 판단된다.

The contamination in soil, underground water and river environment became serious due to illegal waste dumping. In this study, our research group analyzed the oil species of illegally disposed oils from J City. After pretreating the mixture of oil, water and solid phases to obtain homogeneous phase components, the physical property analysis, atom analysis, and gas chromatography were performed. From the results showing 11.8% of oxygen content, $-6^{\circ}C$ of pour point and chromatogram pattern. the contaminated oil was identified as a vegetable one. High performance liquid chromatography (HPLC) analysis was also performed in order to know what kind of vegetable oil was, and the ratio of LLO, OOL and POL was found to be high indicating that the disposed oil is majorly the used soybean oil with some vegetable oil mixtures. This study can be used for identifying contaminators for oils from the illegal waste dumping.
