PI: Parker, David B.Proposal: 1428096Title: MRI: Acquisition of a Gas Chromatograph/Mass Spectrometer-Flame Ionization Detector (GC/MS-FID) for Research in Environmental and Agricultural SciencesSignificanceThe instrument purchased through this project will enable groundbreaking research that will support human and animal health, the cleanup and protection of the environment, and the development and vitality of the economy. For example, the results of research on environmental toxicology may help policymakers make decisions regarding regulations that protect human and ecological health; the results of research on fatty acid composition of beef may allow beef producers to significantly improve the nutritional profile of their product, thereby improving health for millions of people who consume the meat; and the results of research on feed efficiency in beef production may help beef producers increase production and drive economic growth.In addition to the significant social benefits of the research itself, this project will benefit the research and education communities through efforts to support technology transfer, broaden participation of underrepresented groups (women and minority researchers and students are directly involved), and increase interest and participation in STEM education at the undergraduate and K-12 levels.Technical DescriptionThe addition of a GC/MS-FID to WTAMU?s Core Lab will enable research activities that will generate new knowledge in the following areas: The impacts of hazardous organic chemical releases into the environment: The GC/MS-FID will be used to determine the concentrations of hydrocarbons in environmental media (e.g., surface water, sediment, flora) and fauna at oilfield-contaminated sites, and to collect analytical data to measure the uptake, bioaccumulation, and toxic dose of complex mixtures of hydrocarbons in reptile, amphibian, and bird species. The ability to analyze organic chemicals, many of which can be carcinogens, at parts per million and parts per billion levels, will enable research advancing knowledge of the fate, transport, and ultimate toxicity of these chemicals in the environment. The fatty acid composition of red meat: These fatty acids have been related to product shelf life and nutritional value. They have also been shown to affect human cholesterol levels and human heart disease. The GC/MS-FID will be used to quantify fatty acids in meat products, in studies designed to generate new knowledge on the effects of animal breed; feeding of ethanol byproducts, grass, and grain; and cooking and temperature on fatty acid composition.

PI：Parker，David B. 提案：1428096 标题：MRI：购买气相色谱仪/质谱仪-火焰电离检测器 (GC/MS-FID)，用于环境和农业科学研究 意义 通过该项目购买的仪器将实现突破性的研究，支持人类和动物的健康、环境的清理和保护以及经济的发展和活力。例如，环境毒理学的研究结果可以帮助政策制定者做出有关保护人类和生态健康的法规的决策；对牛肉脂肪酸成分的研究结果可能使牛肉生产商能够显着改善其产品的营养成分，从而改善数百万食用肉类的人的健康；牛肉生产中饲料效率的研究结果可能有助于牛肉生产者提高产量并推动经济增长。除了研究本身的显着社会效益外，该项目还将通过支持技术转让、扩大代表性不足群体的参与（女性和少数族裔研究人员和学生直接参与），并提高本科生和 K-12 级别对 STEM 教育的兴趣和参与。技术说明WTAMU 核心实验室增加了 GC/MS-FID将使研究活动成为可能这将产生以下领域的新知识： 危险有机化学品释放到环境中的影响：GC/MS-FID 将用于确定环境介质（例如地表水、沉积物、植物群）中碳氢化合物的浓度，以及油田污染地点的动物群，并收集分析数据以测量爬行动物、两栖动物和鸟类对碳氢化合物复杂混合物的吸收、生物累积和有毒剂量。分析有机化学物质（其中许多可能是百万分之一和十亿分之一的致癌物质）的能力将使研究能够增进对这些化学物质在环境中的归宿、运输和最终毒性的了解。红肉的脂肪酸组成：这些脂肪酸与产品的保质期和营养价值有关。它们还被证明会影响人类胆固醇水平和人类心脏病。 GC/MS-FID 将用于量化肉制品中的脂肪酸，旨在产生有关动物品种影响的新知识的研究中；饲喂乙醇副产品、草和谷物；以及烹饪和温度对脂肪酸组成的影响。
