MRI: Acquisition of a Gas Chromatograph/Mass Spectrometer-Flame Ionization Detector (GC/MS-FID) for Research in Environmental and Agricultural Sciences

PI：Parker，David B.Proposal：1428096标题：MRI：获得用于环境和农业科学研究的气相色谱/质谱仪-火焰电离检测器(GC/MS-FID)意义通过该项目购买的仪器将使开创性研究能够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，环境毒理学的研究结果可能有助于政策制定者就保护人类和生态健康的法规做出决定；牛肉脂肪酸组成的研究结果可能使牛肉生产商显著改善其产品的营养状况，从而改善数百万消费牛肉的人的健康；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。除了研究本身的显著社会效益外，该项目还将通过努力支持技术转让，扩大代表不足的群体的参与(妇女和少数族裔研究人员和学生直接参与)，使研究和教育界受益，技术描述在华大S核心实验室增加GC/MS-FID将使研究活动能够在以下领域产生新知识：向环境中释放危险有机化学品的影响：GC/MS-FID将被用来确定环境介质(如地表水、沉积物、植物)和油田污染场地动物中的碳氢化合物浓度，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、生物累积和毒性剂量。分析有机化学品的能力，其中许多可能是致癌物质，在百万分之几和十亿分之几的水平上，将使研究能够推进对这些化学品在环境中的命运、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的胆固醇水平和人类心脏病。GC/MS-FID将用于对肉类产品中的脂肪酸进行量化，研究旨在产生关于动物品种、乙醇副产品、草和谷物的饲养以及烹饪和温度对脂肪酸组成的影响的新知识。

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.
