摘要深水地平线石油泄漏的情况和由此产生的多年自然资源损害评估（NRDA）调查对传统的石油泄漏指纹协议提出了挑战，包括泄漏石油的快速风化，多年进行的分析中实验室内可重复性的实际方面，马孔多油井泄漏的原油在地球化学上与墨西哥湾北方其他泄漏和自然渗漏的原油相似。本文介绍了一种三层的溢油指纹识别方法，主要是基于现有的定量方法的修改，这是用来比较近1,600油性基质NRDA样本的泄漏马孔多油。该方法还用于比较新鲜的马孔多石油与墨西哥湾北方的遗传相关原油，在大多数情况下，可以区分马孔多石油与该地区密切相关的石油。
ABSTRACT The circumstances of the Deepwater Horizon oil spill and the resulting multiyear natural resources damage assessment (NRDA) investigation presented challenges to conventional oil spill fingerprinting protocols that included rapid weathering of the spilled oil, the practical aspects of intra-laboratory reproducibilty in analyses conducted over multiple years, and the fact that spilled Macondo well oil was geochemically similar to other spilled and naturally seeped crude oils from the northern Gulf of Mexico. This article describes a three-tiered oil spill fingerprinting method, based largely upon modification of existing quantitative methodology, that was used to compare nearly 1,600 oily matrix NRDA samples to the spilled Macondo oil. The method was also used to compare fresh Macondo oil to genetically related crude oils from the northern Gulf of Mexico, and in most cases could distinguish Macondo oil from closely related oils from the region.
