摘要
随着城市化、工业化进程的不断推进,大气颗粒物成为影响我国城市环境空气质量的首要污染物。对近年来我国颗粒物浓度变化、气象条件与颗粒物之间的关系、颗粒物中化学成分、微观形貌及来源解析和对人体健康的危害进行概述和总结,并将影响颗粒物污染的特殊情况(沙尘天气、特殊节假日、秸秆焚烧和累积效应等)也进行了分类分析,结合目前的研究现状及国内成功经验提出了颗粒物污染防治的对策。
With the development of urbanization and industrialization,atmospheric particulate matters become the primary atmospheric pollutant affect Chinese urban atmospheric quality. This paper reviewed the variation of ambient particulate concentration,interrelationship among meteorological factors and particulate matter,chemical composition,microstructures,source apportionment of atmospheric particulate matters and harms to human health in recent years. Furthermore,special cases such as sandstorm,special holiday,straw burning and cumulative effect were also discussed. Finally,combining with current research status and domestic successful experience,countermeasures for particulate matter prevention and control were put forward.
