中文摘要：

率先在国土资源领域培育并形成相对稳定的元素化学形态（价态、金属有机化合物等）分析及其生态环境地球化学应用研究团队,采用高效液相色谱-电感耦合等离子体质谱联用技术,开展生态环境地球化学样品中痕量溴、碘、砷、镉、汞、锡、铅、铬、硒等有益有害元素的价态、金属有机化合物等形态分析方法研究,初步建立了有益有害元素形态分析体系。建立的形态分析方法灵敏度高、检出限低,具有创新性和实用性,工作成果在国内外期刊发表论文20篇。形态分析方法在我国环境地球化学研究中得到应用并取得了良好的应用成果,从形态分析水平上表征元素的环境地球化学及其健康效应在国内外属于探索性工作。

英文摘要：

The research party for elements speciation analysis and environmental geochemistry application in land and resources geological field was organized.Speciation analysis methods for trace bromine,iodine,arsenic,cadmium,mercury,tin,lead,chromium,selenium and other elements in ecological environmental samples were studied and the speciation analysis system was initially established.The methods designed are innovative and practical with high sensitivity and low detection limit.20 papers have been published in international journals.The speciation analysis method has been well applied to the study of environmental geochemistry,with good results achieved.The understanding of the characteristics of the elements in environmental geochemistry and the study of their potential health effects with a thorough speciation interpretation belong to very new and exploratory work both in China and abroad in recent years.These research results can be applied to the analysis of the origin of mineral deposits and the genesis of oil and gas.
