RAPID: MRI - Acquisition of an Accelerated Solvent Extractor (ASE) to Rapidly Extract Petroleum Hydrocarbons from Atmospheric Samples in the Field During the 2010 Hurricane Season

PI要求MRI RAPID提供资金，以获得加速溶剂萃取器（ASE），以便更快速有效地从与深水地平线石油泄漏相关的环境样品中提取碳氢化合物。该提案补充了最近由美国国家科学基金会化学海洋学项目资助的墨西哥湾石油泄漏RAPID项目，该项目旨在量化2010年飓风季节通过深水地平线海面浮油的飓风通过大气沉积造成的碳氢化合物从海洋到陆地的转移。这将是有史以来第一次针对通过降雨将石油产品从海洋转移到陆地的研究。自最初的RAPID提案提交以来，飓风亚历克斯带来的风暴潮扩大了许多墨西哥湾沿岸国家的沿海暴露。这需要在更广泛的地理采样网格上进行采样，将总采样数从24个增加到144个，并包括采样空气，雨水和湖水！因此，更多的样品将需要采用更快的提取过程，以确保在2010年飓风季节及时分析。本研究的结果可能表明，受2010年飓风影响的高地地区的生态系统健康受到深水地平线衍生碳氢化合物干湿沉积的严重损害。这将是第一次这样的测量。

The PI requests MRI RAPID funding to acquire an Accelerated Solvent Extractor (ASE) to more rapidly and efficiently conduct hydrocarbon extractions from environmental samples related to the Deepwater Horizon oil spill. This proposal complements a Gulf oil spill RAPID recently funded by the NSF Chemical Oceanography program to quantify marine-to-land transfer of hydrocarbons via atmospheric deposition from hurricanes that pass through the Deepwater Horizon surface slick during the 2010 hurricane season. This will be the first study ever to address marine-to-land transfer of petroleum products via rainfall. Since submission of the original RAPID proposal storm surge from Hurricane Alex has expanded the coastal exposure of many of the Gulf Coast States. This necessitates sampling across a broader geographical sampling grid increasing the total sample count from 24 to 144 and includes sampling air, rainwater, and lake water! As a result a greater number of samples will necessitate adopting a faster extraction process to ensure timely analyses throughout the 2010 hurricane season.Broader Impacts The results from this study may provide an indication of ecosystem health in upland areas affected by 2010 hurricanes is severely compromised by wet and dry deposition of Deepwater Horizon-derived hydrocarbons. These will be the first such measurements.
