0338406Davis, University of MarylandProfessor Allen P. Davis, Director of the Maryland Water Resources Research Center of the University of Maryland proposes to collaborate in environmental remediation research with Dr. Kyoung-Woong Kim of the Kwangju Institute of Science and Technology. The detailed research investigation will be funded through the Korean side via a companion KOSEF proposal. This NSF proposal requests support for travel to Korea by the U.S. team and some laboratory supplies. The goal of their research is to develop advanced mine tailings characterization techniques and remediation technologies for the removal and/or stabilization of heavy metals and arsenic in contaminated mine materials at several abandoned mine sites in Korea. As part of the project, four U.S. students (2 each for 2 summers) will travel to Korea to learn first hand about mine tailings characterization and remediation technologies, but also to be exposed to the environmental problems, research, and approaches to solutions in Korea. Intellectual Merit: This research will provide information about tailing characteristics and factors affecting the behaviors of metals and arsenic in the tailings. Both metals-removal and stabilization technologies will be advanced through fundamental laboratory and pilot investigations on characterization, monitoring, and remediation of soils and mine tailings. Collaboration between Dr. Kim and co-workers in Korea, together with Dr. Davis and his students, creates a unique team to address the mine tailings problem and for information exchange. Dr. Davis is an engineer with experience in heavy metals chemistry, while Dr. Kim is a geochemist whose recent work has involved new biomarker techniques to quantify metal contamination in soils and to monitor the progress of remediation and stabilization processes. Work will be done at both the University of Maryland, with excellent access to laboratory and instrumentation facilities, and in Korea, where the investigators will have easier access to mine tailings and a regulatory environment that will permit the necessary field studies.Broader Impacts: Benefits to both the U.S. and Korean teams include learning new analysis and remediation techniques and gaining experience with different instrumentation. This experience will broaden the global understanding of environmental issues of all participants, but particularly the U.S. student participants. A special effort will be made to attract students from underrepresented groups to this project, primarily through personal contact with other faculty members at the University of Maryland and at local Historically Black Institutions. Both the PI and the Korean counterpart have excellent records in dissemination of results through conferences, refereed venues, and web sites. Nonetheless, the greatest benefit of this work may be the reduction of heavy metals and arsenic levels in agricultural areas near the abandoned metal mines in Korea that will be studied. This has been a significant environmental problem in Korea since local populations are being directly exposed to the contamination. The results of this work will reduce the metal toxicity risk to those local exposed populations.

马里兰大学马里兰水资源研究中心主任Allen P.Davis教授建议与光州科学技术研究所的KYoung-Woong Kim博士在环境修复研究方面进行合作。详细的研究调查将通过韩方通过一项配套的科斯夫提案提供资金。NSF的这项提案要求为美国团队前往韩国的旅行提供支持，并提供一些实验室用品。他们的研究目标是开发先进的尾矿表征技术和修复技术，以消除和/或稳定韩国几个废弃矿场受污染的矿山材料中的重金属和砷。作为该项目的一部分，四名美国学生(每人两名，为期两个暑假)将前往韩国，亲身了解尾矿的特性和修复技术，同时也将接触到韩国的环境问题、研究和解决方法。智力价值：这项研究将提供有关尾矿特性和影响尾矿中金属和砷行为的因素的信息。将通过对土壤和尾矿进行表征、监测和修复的基础实验室和试点调查，推动金属去除和稳定化技术的发展。金博士和他在韩国的同事、戴维斯博士和他的学生之间的合作，创建了一个独特的团队来解决尾矿问题和信息交流。戴维斯是一名在重金属化学方面有经验的工程师，而金博士是一名地球化学家，他最近的工作涉及新的生物标记物技术，用于量化土壤中的金属污染，并监测修复和稳定过程的进展。工作将在马里兰大学和韩国进行，马里兰大学拥有便利的实验室和仪器设施，韩国的调查人员将更容易接触到尾矿和允许进行必要实地考察的监管环境。广泛的影响：美国和韩国团队的好处包括学习新的分析和补救技术，并获得不同仪器的经验。这一经历将扩大所有参与者，特别是美国学生参与者对环境问题的全球理解。将特别努力吸引代表人数不足的群体的学生参加这个项目，主要是通过与马里兰大学和当地历史上有黑人背景的机构的其他教职员工进行个人接触。国际和平研究所和韩国对应机构在通过会议、裁判场所和网站传播成果方面都有很好的记录。尽管如此，这项工作的最大好处可能是降低将被研究的韩国废弃金属矿附近农业区的重金属和砷水平。这在韩国一直是一个严重的环境问题，因为当地民众正直接暴露在污染中。这项工作的结果将降低当地暴露人群的金属毒性风险。
