| 摘 要： | 大气细颗粒物（PM2.5）的危害与其化学组分密切相关。本文详细介绍了PM2.5的主要组分，包括水溶性无机盐离子、元素碳和有机碳、痕量元素以及地壳元素等。PM2.5的组分受不同因素影响会有所变化。本文总结了季节、地域和特殊污染过程三个主要影响因素，并且比较了几个不同城市的PM2.5组分，对PM2.5的组分研究具有一定意义。

| Abstract: | The harm of aerosol fine particle matter（PM2.5） is in close relation to its chemical composition. This paper reviews main composition of PM2.5, including water soluble ions, EC/OC, trace elements and crustal elements. Different influence factors can make PM2.5 composition change. Season, region, and special air pollution process are summarized in this paper as main influence factors, PM2.5 chemical compositions of some cities are also compared in the paper, which has certain significance for the chemical composition research of PM25. |
