【摘要】大气细颗粒物PM2.5是大气气溶胶的一部分,由于其粒径小以及可为毒性物质提供载体,对环境和人体的健康产生很大的影响.本文总结了国内外有关细颗粒物PM2.5的研究现状,主要围绕细颗粒物PM2.5的物理化学特征与分析方法、健康效应、来源解析、及其对能见度的影响等方面进行了论述,并对其研究动向进行了展望.更多还原

【Abstract】 Fine particles,or PM_2.5（particulate matter with an aerodynamic diameter less than 2.5 μm）,constitute an important type of aerosol.Fine particles have serious impacts on environment and human health due to their smaller sizes and their association with toxic matters.This paper has summarized the research progress of urban airbourne fine particles.In particular,characterization of physical and chemical properties,chemical analysis methods,health effect,source apportionment,and the effect on visibility,of the PM_2.5,have been introduced.Finally,the research prospect of PM_2.5 is described.更多还原
