摘要
大气细粒子PM2.5是大气气溶胶的一个组成部分,由于其粒径小,比表面积大,可以为有毒物质提供载体,所以它对环境和人体健康都有很大的影响。本文主要从PM2.5的危害、研究方法和沙尘细粒子的研究进展来阐述国内外细粒子的研究现状,并对其今后研究热点及新方向进行了展望。
The fine particles, (PM2.5), are a part of the atmospheric aerosols. Due to their small sizes and high specific surface areas, they can carry toxic substances, so it affects environment and human health greatly. In this paper, it summarizes domestic and foreign research progress in the hazards and research methods of PM2.5., and dust fine particles. Some hot topics and new directions of research in the future study of fine particles are in prospect.
