选择长岛典型的两个旅游景点的岩石和岸滩附着的8个溢油样品,对样品中的饱和烷烃、萜烷、甾烷及多环芳烃化合物的分布特征及典型生物标志物诊断比值进行了比对分析.t检验结果表明,置信度为95%时,8个油样的生物标志物诊断比值指标均不能够完全匹配,不可判定其来自同一油源.九丈崖溢油样品之间差异性高于月牙湾.可见,长岛九丈崖岩石和月牙湾岸滩附着溢油样品之间具有较大相似度,但指纹特征各不相同,部分样品差别较大,具有混合油的指纹特征,为多次溢油的混合油样.
Eight oil spill samples from rocks and coasts of two typical tourist spots in Long Island were selected to investigate the distribution characteristics of typical alkanes, terpanes, steranes and polycyclic aromatic hydrocarbons (PAHs) in samples and the diagnostic ratios of typical biomarkers Comparative analysis.t test results show that the confidence ratio of 95%, the eight oil biomarkers diagnostic ratio indicators can not be fully matched, can not be judged from the same oil source. Which is higher than that of Crescent Bay.It can be seen that there is a large similarity between the samples of oil spilled on the Jiuzhangya of Long Island and the crescent of Wanli Bay, but the fingerprints have different features and some of the samples are quite different. Multiple oil spills.
