摘　　要：大气颗粒物成分复杂,容易对环境和人体健康产生较大影响,是雾霾的主要来源。如何对大气颗粒物及其成分的来源、形成和迁移转化过程进行表征一直是大气环境科学研究中的重要课题。近年来,稳定同位素技术被广泛应用到环境污染物的来源示踪研究中。本文综述了大气颗粒物的研究进展,重点围绕大气颗粒物中的轻稳定同位素组成(主要包括碳、氮、硫和氧的稳定同位素),结合大气颗粒物的时空变化特征及特定的同位素数学模型,对大气颗粒物中物质的来源、形成过程和贡献等研究进行分析总结,并对稳定同位素技术在未来大气颗粒物研究中的应用发展趋势进行探讨。Atmospheric particulate matter,regarded as the main source of smog and haze,causes a great impact on the environment and human health due to its complex composition. For scientific research in the atmospheric environment,it is an important issue to characterize the source,formation,migration and transformation processes of atmospheric particulate matter. In recent years,stable isotopic techniques are widely employed in tracing air pollutants. This paper aimed to review the studies related to stable isotopic composition of atmospheric particulate matter,and focused on the light stable isotopic composition of atmospheric particles,including the stable isotopes of carbon,nitrogen,sulfur and oxygen. Combined with spatial and temporal variation of atmospheric particulate matter and some certain isotopic mathematical models,this paper analyzed and summarized the researches on the origin,formation,and contribution of components in atmospheric particulate matter,and discussed the developing trend of applications of stable isotopic techniques in the future study.
