这项建议是要获得一种最先进的仪器，以确定各种样品中重金属的浓度和分子组成。该设备将有助于推进对多个学科中重金属行为的科学理解，包括工程学（储能、纳米技术和材料工程）、环境研究（环境工程、环境健康和地球科学）和健康科学（流行病学和医学）。拟议中的研究将利用伊利诺伊大学芝加哥分校（UIC）现有的科学仪器基础设施，通过专用的核心设施为整个芝加哥大都市区的研究人员提供服务。该仪器直接支持的研究对国家的可持续未来至关重要，包括下一代储能电池的研究以及重金属和工程纳米颗粒对环境和健康的影响。除了这些直接的科学影响外，该仪器的采购将加强UIC的教育和科学培训，UIC是最多样化的校区之一。将采购的具体仪器是电感耦合等离子体质谱仪（ICP-MS）。高灵敏度ICP-MS是分析各种样品中的元素如Pb、As、Se、Cu、Sb、Cd、Pd、Pt、Ag和Hg所必需的，这些样品包括土壤、沉积物、水、空气、生物流体、头发、饮用水、食品和先进的能源材料。这种ICP-MS仪器将具有最高的灵敏度和最广泛的能力系统，可用于复杂基质中困难化合物的特定分离和分析，以服务于不同的用户群体。该研究团队包括调查人员和用户，他们包括各种应用，包括环境污染，污染物归宿和运输，地球化学，毒理学和药物暴露研究，化学，纳米技术和材料科学。

This proposal is to acquire a state-of-the-art instrument to characterize the concentrations and molecular composition of heavy metals in various samples. This equipment will help advance the scientific understanding of heavy metal behaviors across several disciplines, including engineering (energy storage, nanotechnology, and materials engineering), environmental studies (environmental engineering, environmental health and earth science), and health sciences (epidemiology and medicine). The proposed research will leverage the existing scientific instrumentation infrastructure at the University of Illinois at Chicago (UIC) for the benefit of researchers across the Chicago metropolitan area through a dedicated core facility. Research directly supported by this instrumentation is critical to the sustainable future of the nation, including studies of next-generation batteries for energy storage as well as the environmental and health impacts of heavy metals and engineered nanoparticles. In addition to these direct scientific impacts, acquisition of this instrument will strengthen the educational and scientific training at UIC, one of the most diverse campuses.The specific instrumentation to be acquired is an inductively-coupled plasma mass spectrometer (ICP-MS). High sensitivity ICP-MS is necessary to analyze elements such as Pb, As, Se, Cu, Sb, Cd, Pd, Pt, Ag, and Hg in a variety of samples, including soil, sediment, water, air, biological fluids, hair, drinking water, food, and advanced energy materials. This ICP-MS instrumentation will have the highest sensitivity and broadest capability system available for the specific isolation and analysis of difficult compounds in complex matrices to serve the diverse user community. The research team includes investigators and users who comprise a wide variety of applications, including environmental contamination, pollutant fate and transport, biogeochemistry, toxicology and medicinal exposure research, chemistry, nanotechnology, and materials science.
