Abstract
In order to identify the origin and nature of the spilled oil in the potential source, we analyzed the concentrations of specific fuel constituents in fuel standard and environmental samples. The ratios of pristane/phytane are virtually unaltered because these compounds have the same bolatility in environmental samples. These were useful to identify the source of the fuel oil and to assess the effect of microbial degradation and weathering of the fuel oil. We analyzed the ratios of pristane/phytane in neat white kerosene, boiler kerosene, JP-8 and diesel products from L and S gas station. The ratios of pristane/phytane in L-white kerosene and JP-8 was 3.10 $\pm$0.03 and 1.77 $\pm$ 0.01, respectively. Otherwise, the ratios of pristane/phytane in water phase after distribution of fuel oil and water was 2.97 $\pm$0.02 in case of white kerosene and 1.65 $\pm$ 0.02 in case of JP-8. It is apparent from the results that the ratios of pristane/phytane were as product-specific, especially between kerosene and JP-8, and therefore, can also be used for fuel type identification in free products and groundwater samples which were collected in monitoring wells.

잠재오염원에서 누출된 유류의 기원을 확인하기 위해서 표준연료와 환경시료중의 유류 구성성분의 농도를 분석하였다. pristane/phytane의 비는 환경시료 중 같은 휘발성을 가지고 있기 때문에 실질적으로 변하지 않는다. 이것은 미생물분해와 풍화의 영향을 평가하고 유류의 오염원을 확인하는데 유용하였다. L과 S 주유소에서 백등유, 보일러등유, JP-8, 경유의 pristane/phytane 비를 측정하였다. L-백등유와 JP-8에서 pristane/phytane 비는 각각 3.10$\pm$0.03, 1.77$\pm$0.01였으며, 유류와 물을 분배시킨 후 물층에서 pristane/phytane 비는 백등유 2.97$\pm$0.02, JP-8 1.65$\pm$0.02였다. pristane/phytane 비는 백등유와 JP-8을 구분하는 유효하였으며, 또한 관측정에서 수집된 자유상유류와 지하수시료에서 유종을 확인하는데 유용하였다.
