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，以支持在雅阁与教师早期职业发展（CAREER）计划，NSF 97-87提交建议的指导方针提出的项目。 因此，它具有研究和教育两个组成部分。 研究人员的研究目标是开展工作，表征溶解有机碳与水污染物的非共价反应，影响其生物利用度，在含水层中的可转移性和其他因素，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已从诺曼垃圾填埋场渗滤液中分离出来，包括腐殖酸、富里酸和亲水性有机物。 研究人员计划使用氘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，以及吡啶和喹啉，以表征它们与天然有机含碳物质的反应。 主要研究员的教育部分有一个外展部分，让中学教师、学生和本科生参与环境研究，重点是实际问题，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。 调查员计划为高中生开设一个暑期课程，他们将协助设计一个研究项目，由他们在下一学年进行。 研究人员还计划在本科课程中使用先进的分析仪器，并将其研究成果整合到工程设计和系统实施中，以解决危险废物管理问题。 ***

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. ***
