Acquisition and Upgrade of an Inductively Coupled Plasma Emission (ICP-ES) Laboratory of Geological, Oceanographic, and Environmental Chemical Research

小行星9724282 通过主要研究仪器（MRI）计划提供的这笔赠款提供了10万美元，作为购买电感耦合等离子体发射光谱仪（ICP-ES）的部分支持，用于快速分析各种样品基质中的主要和微量元素浓度，包括天然沃茨，沉积物，岩石和生物组织。 将利用这一新仪器的分析能力进行的具体研究包括利用对海水和沉积物样本的主要元素和微量元素分析来推断海洋过去的状况（即初级生产力、生物矿物的保存、风成微粒流向海底等），对在南极洲回收的火山灰进行地球化学研究，以用于跨南极山脉的物源、年代对比和构造历史研究，对内华达州山脉伸展区的岩基花岗岩进行岩石学研究，以阐明其形成过程中可能涉及的地幔，研究高应变片岩和片麻岩的主要和微量元素组成，以了解变质作用和生态毒理学研究期间的扩散质量转移重金属对淡水植物光合作用的影响。该仪器将补充该区域内几个机构（即哈佛、麻省理工学院、世界卫生组织、URI和布朗）最近购置的几台ICP-MS仪器的分析能力，从而使BU ICP-ES成为一个真正的主要和微量元素地球化学区域设施。 ***

9724282 Murray This grant, made through the Major Research Instrumentation (MRI) Program, provides $100,000 as partial support of the costs of acquiring an inductively coupled plasma emission spectrometer (ICP-ES) for rapid analyses of major and trace element concentrations in a variety of sample matrices including natural waters, sediments, rocks and biological tissues. Specific studies that will take advantage of the analytic capabilities of this new instrument include utilize major element and trace element analyses of seawater and sediment samples to make inferences about past conditions in the oceans (i.e. primary productivity, preservation of biogenic minerals, eolian particle flux to the seafloor etc.), studies of the geochemistry of volcanic ashes recovered in Antarctica for use in provenance, chronologic correlation and tectonic history studies of the Transantarctic Mountains, petrologic studies of batholith granites in the Sierra Nevada extensional region to elucidate possible mantle involvement in their formation, studies of the major and trace element compositions of high strain schists and gneisses to understand diffusional mass transfer during metamorphism and ecotoxologic studies of heavy metals in freshwater alga tissues and their possible effects on photosynthesis. This instrument will complement the analytical capabilities of several ICP-MS instruments recently acquired at several institutions within this region (i.e. Harvard, MIT, WHOI, URI and Brown), thus making the BU ICP-ES a truly regional facility for major and trace element geochemistry. ***
