摘要
PM2.5由于其较小的粒径、巨大的比表面积及较大的危害性等特点成为全球大气环境的研究热点。针对近年来中国各地持续出现雾霾天气,空气质量急剧下降的现状,总结了中国有关PM2.5的研究现状,主要围绕PM2.5的污染特征、化学组成以及来源解析等方面的研究进行了综述,并探讨了PM2.5的质量浓度水平、与PM10的相关性及其对能见度的影响。针对目前中国PM2.5的污染与监管现状提出了改善大气环境的一些建议。
PM2.5has become a research hotspot of global atmospheric environment because of its small particle size,large specific surface area and great dangers.In this paper,according to the nationwide haze weather phenomenon and sharp declined air quality status in recent years,the domestic research status about PM2.5is summarized.Pollution characteristics,chemical composition and source apportionment of PM2.5are overviewed.At the same time,the concentration levels of PM2.5,its correlation with PM10 and the influence to visibility are discussed.In the light of pollution and regulatory status of PM2.5,some suggestions are put forward to improve the atmospheric environment in China.
