Project Summary/Abstract (Development Core) The Development Core (DC) and the Untargeted Analysis Resource Core (UARC) will collaborate, with the overall aims to increase the range of analytes or biological markers that are detected and identified that reflect environmental exposures. The DC will work with the Big Data Analytics of UARC to prioritize the sourcing of compounds. The DC will optimize extraction procedures for new matrices, in addition to the matrices already analyzed (e.g., urine, serum, plasma, feces, saliva and sweat), and will conduct analyses of biospecimens collected and stored under different conditions to inform best practices for epidemiology studies. They will establish an untargeted method using gas chromatography coupled to an orbitrap mass spectrometer (GC-Q- Exactive) to expand the services offered by the UARC. The DC will also use GC- and liquid chromatography (LC)-Mass spectrometry with Multiple Reaction Monitoring (MRMs) and MSn to develop specific broad spectrum panels for rapid quantitative analysis of analytes that are difficult to detect on the untargeted platforms. The DC will be directed by Dr. Timothy Fennell (MPI, RTI), who has extensive experience with chemical exposure, metabolite identification and toxicity, and exposure biomarker development.

项目摘要/摘要（开发核心） 开发核心（DC）和未靶向的分析资源核心（UARC）将与 总体目的是增加检测和鉴定的分析物或生物标志物的范围 环境暴露。 DC将与UARC的大数据分析合作，以优先考虑 化合物。除矩阵外，DC还将优化新矩阵的提取过程 分析（例如，尿液，血清，血浆，粪便，唾液和汗水），将进行生物测量的分析 在不同条件下收集并存储，以为流行病学研究提供最佳实践。他们会的 使用与Orbitrap质谱仪耦合的气相色谱仪建立不靶向的方法（GC-Q- 精确）扩展UARC提供的服务。 DC还将使用GC和液相色谱法 （LC） - 具有多个反应监测（MRM）和MSN的质谱法，以发展特定的宽度 光谱面板，用于快速定量分析分析物，这些分析物难以检测到未靶向的分析物 平台。 DC将由Timothy Fennell博士（MPI，RTI）指导，他在 化学暴露，代谢物鉴定和毒性以及暴露生物标志物的发展。
