| 摘 要： | 在2010年7月16日大连输油管道爆炸事故发生后,在24 h内分别于事故油罐、不同海面厚油膜区域采集原始油样及溢油样品;采用气相色谱质谱联用(GC-MS)对样品中的生物标志物进行检测,通过生物标志物特征比值的变化趋势,对以往溢油鉴别过程中常规生物标志物特征比值进行评价和筛选,并对溢油样品的指纹特征和风化规律进行解析.溢油样品的分析结果表明,在多种因素共同作用的不超过24 h的短期风化过程影响下,筛选排除的生物标志物比值均为国标GB/T 21247—2007中建议的nC17/Pr、nC18/Ph特征比值.化学消油剂与生物消油剂的盲目使用,有可能导致溢油指纹特征的显著变化.

| Abstract: | In this study,the original crude oil and oil spilled samples were collected from the oilcan and the thick film regions within 24 hours after the oil spill occurred on 2010 July 16th.To screen the suitable characteristic ratios for oil spill identification,the feasibility of the selected characteristic ratios were investigated by comparing the changes,and the study on the fingerprints characteristic and weathering rule of spilled oil was done.The results implied that the conventional characteristic ratios such as nC17/Pr and nC18/Ph lost the indication function due to the different processes of 24 h weathering.Blind use of the chemical dispersant and bio-oil dispersant may cause the significant changes for fingerprints characteristic of spilled oil. |
