Monitoring, Modeling, Control, and Ultimate Disposal of Heavy Metal Contaminants in the Environment

环境中重金属污染物的监测、建模、控制和最终处置俄亥俄北方大学(ONU)获得29,664美元，为期12个月的旅行和参与者支持前往蒙古的Edernet矿，通过对蒙古农村天然沸石的吸附性能进行采样和评估，确定主要环境污染媒介的特征。参与者包括PI、ONU土木工程教授Bruce Berdanier博士、南达科他州矿业与技术学院(SDSMT)土木工程教授M.R.Hansen、Oglala Lakota College(OLC)科学外联协调员兼讲师Charles Tinant以及三名美国本科生。牵头的外国对应调查人员是蒙古达尔汗蒙古科技大学(MUST)土木工程教授Tsevel Samdaag和约旦Al Karak Mutah大学(MUJ)土木与环境工程教授ANF Ziadat。规划访问的目的包括探讨制订下述建议的可行性：1)建立一个尾矿风沙迁移的实验模型，以评估将飞灰纳入废流中减少重金属异地迁移的效率；2)确定控制重金属发生和分布的基本界面化学关系；以及3)调查生物指示剂(如树皮、地衣)在被动监测重金属污染方面的效率；以及3)研究生物指示剂(如树皮、地衣)在被动监测重金属污染方面的作用；以及3)研究用于最终处置的混凝土砂浆中重金属的含量。私人投资机构还打算确定在奥格拉拉·拉科塔学院建立一个以这些主题为基础的国际区域教育联盟网站的可行性。

ABSTRACT0803703 Berdanier Monitoring, Modeling, Control, and Ultimate Disposal of Heavy Metal Contaminants in the EnvironmentOhio Northern University (ONU) is awarded $29,664 over 12 months in travel and participant support to travel to the Edernet mine in Mongolia to characterize primary environmental contamination vectors by sampling and assessing the feasibility of adsorption properties presented by naturally occurring zeolites in the Mongolian countryside. Participants include the PI, Dr. Bruce Berdanier, Professor of Civil Engineering at ONU, M.R. Hansen, Professor of Civil Engineering at South Dakota School of Mines and Technology (SDSMT), Charles Tinant, Science Outreach Coordinator and Instructor at Oglala Lakota College (OLC), and three U.S. undergraduate students. Lead foreign counterpart investigators are Tsevel Samdaag, Professor of Civil Engineering, Mongolian University of Science and Technology (MUST), Darkhan, Mongolia; and, Anf Ziadat, Professor of Civil and Environmental Engineering at Mutah University (MUJ), Al Karak, Jordan. Objectives of the planning visit include investigating the feasibility of developing a proposal to: 1) develop an experimental model of aeolean sediment transport of mine tailings in order to evaluate the efficiency of fly ash incorporation into the waste stream in reducing offsite migration of heavy metals; 2) determine the fundamental interfacial chemistry relationships controlling heavy metal occurrence and distribution; and 3) investigate the efficiency of bio-indicators (e.g., tree bark; lichen) in the passive monitoring of heavy metals contamination concrete mortar for ultimate disposal. The PIs also intend to determine the feasibility of establishing an international REU site based at Oglala Lakota College on these themes.
