The work proposed will complete the dissertation research of Miguel Goni on geochemical applications of the 75-100 reaction products (in addition to simple phenols) that are obtained from the CuO method sued to characterize lignins in environmental samples. To date, the P.I.'s have found CuO reaction product mixtures from soils and sediments to include compounds derived from specific amino acids, lipids, cutins, and kelps, along with an extensive suite of lignin-derived phenolic dimers. Three papers describing the cutin work are now submitted and a manuscript on the geochemistries of the amino acid reaction products is in preparation. The P.I.'s propose to wrap up this project by investigating the suites of CuO reaction products: (a) compounds that appear to be unique to kelps and (b) the lignin dimers, which potentially carry novel geochemical information.

本项工作将完成Miguel Goni博士关于CuO法测定环境样品中木质素的75-100个反应产物（除简单酚类外）的地球化学应用的论文研究。到目前为止，私家侦探研究人员发现，土壤和沉积物中的CuO反应产物混合物包括来自特定氨基酸、脂类、岩屑和海带的化合物，以及大量木质素衍生的酚类二聚体。目前已经提交了三篇描述角质工作的论文，一篇关于氨基酸反应产物地球化学的手稿正在准备中。侦探’s建议通过研究CuO反应产物的组合来结束这个项目：(a)似乎是海带特有的化合物和(b)木质素二聚体，它们可能携带新的地球化学信息。
