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.

俄亥俄州北方大学（ONU）环境中重金属污染物的监测、建模、控制和最终处置项目获得29美元，在12个月的旅行和与会者支助中，664人前往蒙古Edernet矿，通过取样和评估天然沸石吸附特性的可行性，确定主要环境污染媒介的特征，蒙古农村。 参与者包括PI，布鲁斯伯丹尼尔博士，土木工程教授在ONU，M.R.南达科他州矿业与技术学院（SDSMT）土木工程教授汉森、奥格拉拉拉科塔学院（OLC）科学推广协调员兼讲师查尔斯·蒂南特和三名美国本科生。 主要的外国对应调查人员是蒙古达尔汗的蒙古科技大学土木工程教授Tsevel Samdaag和约旦卡拉克的穆塔大学土木和环境工程教授Anf Ziadat。 规划考察的目的包括调查以下建议的可行性：1）开发尾矿的空气沉积物运输实验模型，以评估将粉煤灰掺入废物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）调查生物指示剂的效率（例如，树皮;地衣）中的重金属污染混凝土砂浆进行最终处置的被动监测。 PI还打算确定在Oglala Lakota学院建立一个关于这些主题的国际REU网站的可行性。
