Abstract
An estimated 12,547,000 liters (10,900 M/T) of crude oil was spilled in December 2007 after the collision between the oil tanker Hebei Spirit and a barge carrying a crane. More than 375 km of western coastline of Korea were impacted by the spill, threatening the health of natural marine ecosystem and various mariculture activities. Even five years after the spill, highly weathered oil residues were frequently observed together with newly stranded ambient contaminations and their sources need to be traced not only for scientific reason but also for forensic purpose.Oils from different sources have distinct chemical compositions, which can be used to identify the source of oil pollution. The chemical compositions of spilled oils, however, can be altered in the environment by a number of physicochemical and biological processes, making source characterization ambiguous. In addition, the compositional changes can be variable within a stranded oil residue. Surface of stranded oil is more exposed to various weathering processes such as evaporation, dissolution, photooxidation and microbial degradation, while inner part of oilis remained relatively unchanged. In this study, stranded oil residues were analyzed by various analytical methods as source correlation tools, including gas chromatography, mass spectrometry, thin layer chromatography, elemental analysis and stable isotope analysis.
