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

NSF基金将用于购买多集电极电感耦合等离子体质谱计（MC-ICPMS）。MC-ICPMS将促进对亚利桑那州农村环境挑战的理解，包括修复因采矿、人为污染物的采购和运输/命运、火山危害以及全球变化的证据和生态系统响应而受到污染的地区。它将改善一所大学的stem相关教学和研究培训，该大学为亚利桑那州的大量农村人口和美国原住民以及庞大的西班牙裔社区提供服务。新型MC-ICPMS的多样化研究能力将成为新的综合、综合和独特的地球与环境系统博士项目的一部分。MC-ICPMS将推进同位素化学的研究和培训，涵盖地质学、化学/生物化学、人类学、生物学、环境科学和林业项目。有了这台仪器，聚集在一起的研究人员和他们的学生将获得高精度的同位素数据，用于整个质谱的地球化学和地质年代学研究。新的MC-ICPMS将在推进至少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，包括推进与以下相关的知识：(1)造成爆炸性（有时是巨大的）事件的岩浆的聚集和喷发；(2)人为污染；(3)景观与构造演化；(4)大地震与深部周期性流体运移。

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.
