알킬벤젠 패턴에 의한 누출된 유류의 오염원 확인 = The Source Identification of Spilled Oil by the Pattern of Alkyl Benzene

다국어 초록 (Multilingual Abstract)

In order to identify the origin and nature of the spilled oil in the potential source, we analyzed the pattern of alkyl benzene in fuel standard and environmental samples. Alkyl benzene patterns are used for fuel-type identification in weathered environmental samples. Detection of alkyl benzenes was achieved by operating GC/MS in the SIM mode. We chose ions of C6-benzene (m/z 162), C7-benzene (m/z 176) and C8-benzene(m/z 190) for the comparison of this pattern according to the type of fuel. The pattern of alkyl benzene from C6-benzene to C8-benzene was different according to the type of fuel. JP-8 demonstrated an asymmetric distribution pattern with a noticeable difference to that of kerosene. That of kerosene showed a distribution pattern composed of a bundle peaks, while that of JP-8 had two groups of peaks. We found that the alkyl benzene patterns are useful for differentiation between kerosene and JP-8.
