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.

NSF 资金将用于购买多接收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/归宿、火山灾害而受到污染的地区，以及全球变化的证据和生态系统响应。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大量农村人口和美洲原住民以及大量西班牙裔社区提供服务。新的 MC-ICPMS 实现的多样化研究能力将成为新的综合性、综合性和独特的地球与环境系统博士课程的组成部分。程序。 MC-ICPMS 将推进同位素化学领域的研究和培训，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。借助该仪器，聚集的研究人员及其学生将获得高精度同位素数据，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，包括推进以下方面的知识：(1) 岩浆的聚集和喷发，导致爆炸性的、有时是巨大的事件； （二）人为污染； (3) 地貌与构造演化； (4)大地震和周期性的深部流体运移。
