CAREER: Molecular-Level Characterization of Bonding and Bioavailability of Monoaromatic Pollutants Associated wtih Dissolved Organic Carbon

MARK NANNY 9732969这是一个奖项，用来支持一个项目，该项目符合NSF97-87《教师早期职业发展(Career)计划提交建议书指南》。因此，它既有研究又有教育的部分。研究人员的研究目标是开展工作，表征溶解有机碳与影响其生物有效性、含水层中的可转移性和其他因素的水污染物的非共价反应，这些因素可应用于系统的工程设计，以减少垃圾填埋场渗滤液的污染影响。他计划使用的溶解有机化合物是从诺曼垃圾填埋场渗滤液中分离出来的，包括腐植酸、富里酸和亲水性有机物。研究人员计划除了吡啶和喹啉外，还计划使用氚标记的芳香族化合物，如甲苯、乙苯、硝基苯、苯酚、苯胺、苯甲酸和甲氧基苯衍生物来表征它们与天然有机含碳物质的反应。首席调查员的教育部分有一个外展部分，让中学教师、他们的学生和本科生参与环境研究，重点放在实际问题上，例如与当地垃圾填埋场渗滤液管理有关的问题。这个问题涉及环境问题，由于它们的直接重要性、科学和技术的复杂性，预计会激励学生。这位研究人员计划为高中生开设一个暑期项目，帮助他们设计一个研究项目，由他们在下一学年进行。研究人员还计划在本科课堂上使用先进的分析仪器，并将他的研究成果整合到解决危险废物管理问题的系统的工程设计和实施中。S。*

Mark Nanny 9732969 This is an award to support a project proposed in accord with the Guidelines for Submission of Proposals to the Faculty Early Career Development (CAREER) Program, NSF 97-87. As such, it has both a research and educational component. The investigator's research objectives are to conduct work that characterizes non- covalent reactions of dissolved organic carbon with water pollutants that affects their bioavailability, transferability in aquifers and other factors that can be applied to engineering design of systems to reduce the pollutional impact of leachate from landfills. The dissolved organic compounds he plans on using have been isolated from the Norman Landfill leachate and include humic acid, fulvic acid and hydrophilic organic matter. The investigator plans on using deuterium-labeled aromatic compounds such as toluene, ethylbenzene, nitrobenzene, phenol, aniline, benzoic acid and methoxybenzene derivatives in addition to pyridine and quinoline in the characterization of their reactions with natural organic carbonaceous substances. The Principal Investigator's educational component has an outreach component aspect for involving secondary school teachers, their students and undergraduates in environmental research focussed on an actual problem such as those associated with management of the leachate from a local landfill. This problem addresses environmental issues that are expected to motivate students because of their immediate importance, scientific and technological complexity. The investigator plans on inaugurating a summer program for high school students who will assist in designing a research project to be conducted by them during the succeeding academic year. The investigator also plans on implementation of the use of advanced analytical instrumentation in undergraduate classes and integrating the results of his research in the engineering design and implementation of systems for solving hazardous waste management problem s. ***
