A low sulfur fuel oil (LSFO) spill accident occurred in South Korea on December 17, 2019, before the introduction of the International Maritime Organization (IMO) sulfur limit. In this study, chromatograms, percentage weathering plots (PW-plots), and diagnostic ratios (DRs) of LSFOs collected in different areas during in the early spillage were compared for oil spill fingerprint. The source oil was conformed as LSFO according to physical properties and spill oils, like the source oil, show high n-alkanes and low benzo[b]naphto[1,2-d]thiophene (BNT) distribution. In the PW-plots, spill oils exhibited a decreasing trend with the reduction of low-molecular-weight compounds, which were affected by evaporation. The relative difference in the DRs was below 14%, indicating that the source and spill oils matched, excluding the ratios consisting of evaporated compounds. These results showed that spill oils confirmed as LSFO were evaporated during the initial spillage stage, and matched to the source oil.

韩国低硫燃料油漏油指纹

2019 年 12 月 17 日,在国际海事组织 (IMO) 硫含量限制出台之前,韩国发生了低硫燃料油 (LSFO) 泄漏事故。在这项研究中,比较了早期泄漏期间在不同区域收集的 LSFO 的色谱图、风化百分比图 (PW-plots) 和诊断率 (DR),以获取溢油指纹。源油物理性质符合LSFO,溢油与源油一样,正构烷烃含量高,苯并[ b]含量低。]萘并[1,2-d]噻吩(BNT)分布。在 PW 图中,随着受蒸发影响的低分子量化合物的减少,溢油呈下降趋势。DR 的相对差异低于 14%,表明源油和溢油匹配,不包括蒸发化合物组成的比率。这些结果表明,确认为 LSFO 的溢油在初始溢油阶段蒸发,并与源油匹配。
