Abstract
본 연구에서는 유류 오염 토양 중에 함유 되어 있는 다환방향족탄화수소류(PAHs)의 시험방법을 확립하고자 수행되었다. 토양 중 PAHs 시험방법으로 미국 EPA 및 ISO 시험방법 등을 비교검토하고 국 내 오염 토양에 대한 적용성을 검토한 결과, 유류 오염토양의 분석을 위해서는 알루미나 전처리 방법이 보다 효율적인 것으로 나타났으며, 휘발성이 큰 naphthalene, acenaphthene, acenaphthylene, fluorene 등 4 종을 제외한 PAHs 12종에 대한 회수율이 67~107%범위로 나타나 이들 물질에 대한 시험방법을 마련하 였다. 또한, 유류로 오염된 토양 5점을 선정하여 시험방법에 대한 적용성 시험 결과, 분석대상 12종 PAHs 는 모든 시료에서 78.68~275.57 μg/kg로 검출되었으며, 이중 phenanthrene, pyrene, chrysene 등은 전체 농 도의 약 70%로 대부분의 비율을 차지하였다. 특히 BaP의 경우 농도범위는 1.76~24.65 μg/kg으로 나타났다.
