MRI: ACQUISITION OF A MULTICOLLECTOR-ICP-MASS SPECTROMETER FOR MULTIDISCIPLINARY RESEARCH AND TEACHING AT NORTHERN ARIZONA UNIVERSITY

NSF资金将用于购买多收集器电感耦合等离子体质谱仪(MC-ICPMS)。MC-ICPMS将促进对亚利桑那州农村地区环境挑战的了解，包括修复因采矿、人为污染物的来源和运输/命运、火山灾害以及证据和生态系统对全球变化的反应而受到污染的地区。它将改善一所大学与STEM相关的教学和研究培训，这所大学服务于亚利桑那州的大量农村人口和美洲原住民，以及一个大型拉美裔社区。新的MC-ICPMS提供的多样化研究能力将是新的全面、综合和独特的地球与环境系统博士计划的组成部分。MC-ICPMS将推进横跨地质学、化学/生物化学、人类学、生物学、环境科学和林业项目的同位素化学研究和培训。有了这台仪器，聚集的研究人员和他们的学生将获得高精度的同位素数据，用于整个质谱学的地球化学和地质年代学调查。新的MC-ICPMS将在推动至少15名专业科学家及其学生的研究目标方面发挥至关重要的作用，包括增进与以下方面有关的知识：(1)导致有时是巨大爆炸性事件的岩浆的聚集和喷发；(2)人为污染；(3)景观和构造演化；(4)大地震和来自深处的周期性流体迁移。

NSF funds will be used to acquire a multicollector-inductively coupled plasma mass spectrometer (MC-ICPMS). The MC-ICPMS will promote understanding of environmental challenges for rural Arizona, including remediation of areas that have been polluted from mining, sourcing and transport/fate of anthropogenic pollutants, volcanic hazards, and evidence for - and ecosystem responses to - global change. It will improve STEM-related teaching and research training at a university that serves a large rural Arizona and Native American population, as well as a large Hispanic community. The diverse research capabilities enabled by the new MC-ICPMS will be integral to the new comprehensive, integrative, and distinctive Earth and Environmental Systems Ph.D. program. The MC-ICPMS will advance research and training in isotope chemistry that spans the Geology, Chemistry/Biochemistry, Anthropology, Biology, Environmental Sciences and Forestry programs. With this instrument, the assembled investigators and their students will obtain high precision isotopic data for geochemical and geochronological investigations across the mass spectrum. The new MC-ICPMS will play a vital role in advancing the research objectives of at least 15 professional scientists and their students, including advancing knowledge related to: (1) the assembly and eruption of magmas responsible for explosive, sometime giant, events; (2) anthropogenic pollution; (3) landscape and tectonic evolution; and (4) large earthquakes and periodic fluid migration from depth.
