0722579ChoroverThis MRI proposal requests funding for two tandem mass spectrometers with a research focus on water quality and its biogeochemical and anthropogenic controls. Emphasis is placed on emerging contaminants and their carriers, since these constituents are impacting to an increasing degree all aspects of the hydrologic cycle and they pose some of the most complex and broadly relevant challenges for water science and engineering. Faculty in four colleges at University of Arizona (UA), along with collaborators at Arizona State University (ASU) and Northern Arizona University (NAU), are establishing a new multi-user facility dedicated to state-of-the-art water analyses that will provide a keystone for current and future programmatic needs in this cross-cutting area of environmental science, engineering and toxicology. The MRI will be included in this new facility, and will be used by more than 18 engineering and science faculty collaborators with research and teaching programs focusing on groundwater, surface water, drinking water and wastewater. All share the common goal to characterize and quantify dissolved and suspended species in aqueous systems. The MRI request is for (i) liquid chromatography tandem mass spectrometry (LC-MS/MS) and (ii) gas chromatography tandem mass spectrometry (GC-MS/MS).

0722579 Chorover该MRI提案要求资助两台串联质谱仪，重点研究水质及其生物化学和人为控制。重点放在新兴的污染物及其载体，因为这些成分影响到越来越多的水文循环的各个方面，他们提出了一些最复杂的和广泛相关的水科学和工程的挑战。亚利桑那大学（UA）四个学院的教师，沿着与亚利桑那州立大学（ASU）和北方亚利桑那大学（NAU）的合作者，正在建立一个新的多用户设施，致力于最先进的水分析，这将为环境科学，工程和毒理学的这一交叉领域的当前和未来的计划需求提供一个基石。MRI将包含在这个新设施中，并将由超过18名工程和科学教师合作者使用，其研究和教学项目重点是地下水、地表水、饮用水和废水。所有这些都有一个共同的目标，即表征和量化水系统中的溶解和悬浮物质。MRI请求用于（i）液相色谱串联质谱（LC-MS/MS）和（ii）气相色谱串联质谱（GC-MS/MS）。
