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：获取气相色谱仪/质谱-火焰离子化检测器（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开创性的研究，将支持人类和动物健康，环境的清理和保护，以及经济的发展和活力。例如，环境毒理学研究的结果可能有助于决策者就保护人类和生态健康的法规作出决定；对牛肉脂肪酸组成的研究结果可使牛肉生产商显著改善其产品的营养成分，从而改善数百万肉类消费者的健康；牛肉生产中饲料效率的研究结果可以帮助牛肉生产商提高产量，推动经济增长。除了研究本身的重大社会效益外，该项目还将通过支持技术转让，扩大代表性不足群体（妇女和少数民族研究人员和学生直接参与）的参与，以及提高对本科和K-12阶段STEM教育的兴趣和参与，使研究和教育界受益。技术描述：在WTAMU？核心实验室将使研究活动能够在以下领域产生新的知识：有害有机化学物质释放到环境中的影响；GC/MS-FID将用于确定油田污染地点环境介质（如地表水、沉积物、植物群）和动物群中碳氢化合物的浓度，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、生物积累和毒性剂量。分析有机化学物质的能力，其中许多可能是致癌物，在百万分之一和十亿分之一的水平上，将使研究能够推进对这些化学物质在环境中的命运、运输和最终毒性的认识。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。它们也被证明会影响人类的胆固醇水平和人类的心脏病。GC/MS-FID将用于定量肉类产品中的脂肪酸，用于研究动物品种的影响；乙醇副产品、草料和谷物的饲养；而烹调和温度对脂肪酸的组成有影响。
