摘　　要：如今我国对大气的治理,特别是对细微颗粒物(即PM2.5)的治理十分重视。PM2.5对人体健康和大气环境质量都有非常严重的潜在的危害。主要研究黑色金属冶炼行业PM2.5的排放特征,采用静电低压撞击器(electrical low pressure impactor,ELPI)对烟气中的颗粒的粒数分布及质量浓度分布进行在线分析,并对颗粒物的形貌、聚集特性、化学组分及物相组成等进行了深入研究。为分析中国工业排放PM2.5颗粒的来源,及PM2.5对健康、气候的影响提供了数据依据。Now the governance of our atmosphere, in particular, the respirable particular matter （PM2.5） is very serious. The PM2.5 has a very serious potential hazard to human health and the quality of atmospheric environment. This article researches the emissions characteristics of PM2. 5 in ferrous metal smelting and rolling processing industry, using ELPI to analysis the grains distribution and mass concentration of particles in the flue gas online. The samples through automatic smoke tester are got. And the the morphology of the particles, gathered characteristics, chemical composition and phase composition are studied deeply. This article provides a strong basis for the impact of PM2. 5 on health and climate, and analyses the emission sources of PM2.5 particle in Chinese industry.
