The application of mineralogy in environmental sciences will be a major aspect of mineralogical studies in the 21st century. Thi s article provides some e xamples of environmental mineralogy studies carried out in author's laboratory, such as nuclear waste disposal, mineral surfaces, microbial effects on toxic met al reduction and immobilization, atmospheric aerosol particles, and theoretical calculation of intrinsic sorption constants of metal cations on mineral surfaces . Quantitative study of the interactions in the system of mineral-water-micro be at the molecular level will be important for understanding low-temperature g eochemical and biogeochemical processes.%矿物学在环境科学中的应用将是21世纪矿物学研究的一个主要方面. 作者所在实验室曾做过的一些环境矿物学研究的实例有:核废料的处置,矿物表面性质的研究,对有毒金属的还原和固定作用的微生物效应,大气烟尘微粒的研究,矿物表面阳离子的本征吸附常数之理论计算,等等.矿物-水-微生物体系在分子级别上之相互作用的定量研究,对于理解低温地球化学和生物地球化学过程将是重要的.
