In order to determine the source of organic matter and the fingerprint of the oil components, 50 samples collected from the near-surface sediments of the oil spill area in Bohai Sea, China, were analyzed for grain size, total organic carbon, aliphatic hydrocarbons (AHs), and polycyclic aromatic hydrocarbons (PAHs). The concentrations of C15-35 n-alkanes and 16 United States Environmental Protection Agency (US EPA) priority pollutant PAHs were found in the ranges of 0.88-3.48μg g(-1) and 9.97-490.13ng/g, respectively. The terrestrial organic matters characterized by C27-C35 n-alkanes and PAHs, resulting from the combustion of higher plants, are dominantly contributed from the transportation of these plants by rivers. Marine organic matters produced from plankton and aquatic plants were represented by C17-C26 n-alkanes in AHs. Crude oil, characterized by C17-C21 n-alkanes, unresolved complex mixture (UCM) with a mean response factor of C19 n-alkanes, low levels of perylene, and a high InP/(InP+BghiP) ratio, seeped into the oceans from deep hydrocarbon reservoirs, as a result of geological faults.
为了确定有机物来源和油类成分的指纹特征,对从中国渤海溢油区近地表沉积物中采集的50个样品进行了粒度、总有机碳、脂肪烃(AHs)和多环芳烃(PAHs)分析。发现C15 - 35正构烷烃和16种美国环境保护局(US EPA)优先污染物多环芳烃的浓度范围分别为0.88 - 3.48μg g(-1)和9.97 - 490.13ng/g。以C27 - C35正构烷烃和多环芳烃为特征的陆地有机物,源于高等植物的燃烧,主要由河流对这些植物的搬运作用贡献。脂肪烃中以C17 - C26正构烷烃为代表的浮游生物和水生植物产生的海洋有机物。以C17 - C21正构烷烃、平均响应因子为C19正构烷烃的未分辨复杂混合物(UCM)、低含量苝以及高InP/(InP + BghiP)比值为特征的原油,由于地质断层从深部烃类储层渗入海洋。
