摘　　要：选择北京、天津、河北重点控制区的钢铁企业为样本,首先对其排放的PM2.5细颗粒物的单尘颗粒进行采样分析、处理、测定,其次重点对这些颗粒物上携带的多种重金属元素在不同粒径颗粒物中的分布进行研究,最后得出钢铁企业排放PM2.5等颗粒物中携带的K、Ca、Mn、Cu、Zn、Pb、Cr、Ni重金属元素在不同粒径颗粒物中的分布有所不同的结论,为后续治理和控制钢铁企业排放的PM2.5等颗粒物提供有力的依据.In the present paper, iron and steel enterprises in the key control areas ofBeijing- Tianjin- Hebei. Were take as a sample, Firstly, sampling, treatment and determination for PM2.5 particles were made. Secondly, distributions for different diameters of heavy metal elements in the PM2. 5 particles were studied. The results showed that the distributions of K, Ca, Mn, Cu, Zn, Pb, Cr and Ni are different in the different diameter PM2. 5 particles.
