据估计，在“深水地平线”漏油事件中，有410万桶石油和210万加仑的分散剂被释放到墨西哥湾。人们仍然需要关于墨西哥湾灾难的影响和长期影响的信息。本研究的目的是评估受泄漏影响的四个墨西哥湾沿岸州沿海水域中生物可利用的多环芳烃（PAHs）。从2010年5月开始，在一年多的时间里，使用被动采样装置监测多环芳烃的生物可利用浓度。在海岸线涂油之前，所有研究地点都获得了基线数据，从而可以直接比较多环芳烃污染的前后情况。然而，到2011年3月，所有地点的生物可利用多环芳烃含量都达到了油泄漏前的水平。2011年夏季，在阿拉巴马州，多环芳烃浓度再次升高，并伴有与受泄漏影响时相似的化学指纹。化学法医模型表明，多环芳烃浓度升高与不同的化学特征有关。
An estimated 4.1 million barrels of oil and 2.1 million gallons of dispersants were released into the Gulf of Mexico during the Deepwater Horizon oil spill. There is a continued need for information about the impacts and long-term effects of the disaster on the Gulf of Mexico. The objectives of this study were to assess bioavailable polycyclic aromatic hydrocarbons (PAHs) in the coastal waters of four Gulf Coast states that were impacted by the spill. For over a year, beginning in May 2010, passive sampling devices were used to monitor the bioavailable concentration of PAHs. Prior to shoreline oiling, baseline data were obtained at all the study sites, allowing for direct before and after comparisons of PAH contamination. Significant increases in bioavailable PAHs were seen following the oil spill, however, pre-oiling levels were observed at all sites by March, 2011. A return to elevated PAH concentrations, accompanied by a chemical fingerprint similar to that observed while the site was being impacted by the spill, was observed in Alabama in summer, 2011. Chemical forensic modeling demonstrated that elevated PAH concentrations are associated with distinctive chemical profiles.
