摘 要: 大气物源研究是多学科共同探讨的较为复杂的问题.它对污染物的追踪、污染物的最终解释和评价具有重要意义,并为大气质量控制和环境管理提供合理依据.大气物源研究主要集中在颗粒物矿物学特征、化学成分及同位素组成等几个方面,并用数理统计方法建立起两者的相关关系,据此判别和解释大气污染物的来源.本文从矿物组成和形貌特征、标志性化学成分及同位素示踪等3个方面对近10余年来的研究成果进行较为系统的阐述. The study on sources of aerosols is a complicated multidisciplinary issue, which is significantly important in the source-tracing, explaining and appraising of pollutants. It supplies reasonable foundations for air pollution control and environment managing. The study is focused on the characteristics of mineralogy, chemistry and isotopic compositions of aerosols. Mathematical statistics is applied to distinguish and explain the sources of aerosols. The methods of research in the latest decade are in three types, i.e. mineral composition and corn shape, benchmark chemical composition and isotopic tracing.
