摘要: In order to determine the source of organic matter and fingerprint oil components, 50 samples collected from near-surface sediments spill area in Bohai Sea, China, were analyzed for grain size, total carbon, aliphatic hydrocarbons (AHs), polycyclic aromatic (PAHs). The concentrations C15-35 n-alkanes 16 United States Environmental Protection Agency (US EPA) priority pollutant PAHs found ranges 0.88-3.48μg g(-1) 9.97-490.13ng/g, respectively. terrestrial matters characterized by C27-C35 PAHs, resulting combustion higher plants, are dominantly contributed transportation these plants rivers. Marine produced plankton aquatic represented C17-C26 AHs. Crude oil, C17-C21 n-alkanes, unresolved complex mixture (UCM) with a mean response factor C19 low levels perylene, high InP/(InP+BghiP) ratio, seeped into oceans deep hydrocarbon reservoirs, as result geological faults.
