MRI: Acquisition of a Multi-Channel Ion Chromatograph to Support Geochemical and Environmental Research

该项目由主要研究仪器计划和刺激竞争研究的既定计划（EPSCoR）共同资助。 资金将用于支持购置一台离子色谱仪，该色谱仪可对天然沃茨中的重要分子进行测定和量化。 该IC将直接受益于十个正在进行的地球化学，化学，矿山废物修复，植物学和环境科学与工程项目。 在当地超级基金场地进行砷和金属补救的预期研究对公共卫生和环境恢复有影响。 计划参与当地流域教育计划将使数百名K-12教师及其学生接触到地球化学分析应用程序，以解决当地采矿相关的环境问题。该仪器将支持早期职业和女性地球科学家的研究，并在蒙大拿州农村的两个主要的本科院校进行研究和教学培训，第一代和美洲原住民学生构成了学生的重要组成部分。 PI研究议程的一个特别重点是旨在了解砷和金属污染物如何在环境中循环的调查，研究生物电化学方法以减少农业径流中的硝酸盐，生态系统修复，以及探索黄石温泉中极端微生物介导的地球化学相互作用。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准。

CoxEAR-2117554This project is jointly funded by Major Research Instrumentation Program and the Established Program to Stimulate Competitive Research (EPSCoR). Funding will support acquisition of an ion chromatograph which allows the determination and quantification of important molecules in natural waters. The IC would directly benefit ten ongoing projects in geochemistry, chemistry, mine-waste remediation, botany, and environmental science and engineering. Intended studies of Arsenic and metal remediation at a local Superfund site has implications for public health and environmental recovery. Planned engagement with a local watershed education Program would expose hundreds of K-12 teachers and their students to geochemical analysis applications to local mining related environmental issues. The instrument will support the research of early career and female geoscientists and research and teaching training at two primarily undergraduate institutions in rural Montana where first generation and Native American students make up a significant part of the student body.The IC will support analysis of major cations, anions and organic acids in aqueous samples. A particular focus of the PIs research agenda are investigations aimed at understanding how arsenic and metal contaminants cycle in the environment, study of bio-electrochemical methods to reduce nitrates from agricultural runoff, ecosystems remediation, and exploring extremophile mediated biogeochemical interactions in Yellowstone's hot springs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
