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

这是一个奖项，用于支持根据向教师早期职业发展（Career）计划提交建议的指导方针提出的项目，NSF 97-87。因此，它既有研究成分，也有教育成分。研究者的研究目标是研究溶解有机碳与水污染物的非共价反应的特征，这些反应会影响它们在含水层中的生物利用度、可转移性和其他因素，这些因素可以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已经从诺曼垃圾填埋场的渗滤液中分离出来，包括腐植酸、黄腐酸和亲水有机物质。研究者计划使用氘标记的芳香化合物，如甲苯、乙苯、硝基苯、苯酚、苯胺、苯甲酸和甲氧基苯衍生物，以及吡啶和喹啉，来表征它们与天然有机碳质物质的反应。首席研究员的教育部分有一个外联部分，涉及中学教师、他们的学生和本科生参与环境研究，重点关注一个实际问题，例如与当地垃圾填埋场渗滤液管理有关的问题。这个问题解决的环境问题，预计将激励学生，因为他们的直接重要性，科学和技术的复杂性。研究人员计划为高中生开设一个暑期项目，帮助他们在接下来的学年设计一个研究项目。该研究人员还计划在本科课程中使用先进的分析仪器，并将其研究成果整合到解决危险废物管理问题的工程设计和系统实施中***

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. ***
