Preliminary Discussion on the Source Identification of Oil Spills Based on the Nitrogen Isotopic Characteristics

Abstract:

Oil spill; Source identification; δ15N; Nitrogen isotope proﬁle; biodegradation Abstract. A preliminary evaluation of nitrogen isotope analysis as a novel, alternative method for identifying spilled oils is presented. The nitrogen isotopic compositions of crude oil from different oilfields in China may be significantly different, which provides a way of screening possible sources for spilled oil of unknown origin, especially in areas of heavy tanker traffic carrying oils from different geographical regions. The value of δ15N increases gradually with the degree of biodegradation. This findings can be applied for correlation and differentiation of spilled oils at their lightly to moderately weathered stages.
