SGER: Isolation and Characterization of Dissolved Organic Matter in Katrina Flood Waters in New Orleans

0553112库克本提案中提出的研究将允许建立一个从城市洪水沃茨（UFW）中分离溶解有机物（DOM）的程序。将DOM分离出来并随后对其进行定性，将有助于确定基线。从这一基线洞察DOM分解在UFW内的地球化学将是可能的。 随后提出的模型系统应允许进一步了解DOM的去除是否以及如何促进更快地恢复淹没地区。此外，分离的DOM将用于研究UFW中存在的有机和无机污染物的归宿和传输。此外，分离的DOM将用于微生物生长研究，以了解UFW中的微生物种群。从这些研究提供的数据将允许建模的环境影响的UFWs，并制定战略，以减少微生物种群的UFWs通过控制DOM在这样的沃茨。 此外，分离的样本将提供给全国和世界各地对这一主题感兴趣的其他研究人员。

0553112 Cook The research put forward in this proposal will allow for a procedure to be established for the isolation of dissolved organic matter (DOM) from urban flood waters (UFWs). The isolation of DOM, and its subsequent characterization, will allow for a baseline to be established. From this baseline insight into the biogeochemistry of DOM decomposition within UFWs will be possible. Subsequent proposal of model systems should allow to further understand if and how the removal of DOM facilitates faster recovery of flooded areas. In addition, the isolated DOM will be used to study the fate and transport of organic and inorganic pollutants present within UFWs. Also, the isolated DOM will be used for microbial growth studies to understand microbial population in UFWs. The data provided from these studies will allow for modeling of the environmental impacts of UFWs, and developing strategies to reduce the microbial population in UFWs by controlling the DOM in such waters. In addition, the isolated sample will be made available to other researchers across the Nation and around the world who have scientific interests in this topic.
