| 摘 要： | 研究了鞍山市环境空气中可吸入颗粒物(PM10和PM2.5)中重金属元素分布特征,结果表明鞍山市环境空气可吸入颗粒物中Zn、Pb、Al、Cu四种金属总和所占21种元素比例近85%。重金属元素在不同粒径颗粒物中的浓度水平有明显差别,更易富集在细颗粒物PM2.5上。

| Abstract: | In this paper,the Anshan City in ambient air respirable particulate matter(PM_(10) and PM_(2.5)) in the distribution of heavy metals,the results show that the city of Anshan in the ambient air respirable particulate matter Zn,Pb,Al,Cu four of the 21 kinds of metal elements combined ratio of nearly 85 percent.Heavy metals in particulate matter in different particle size of the difference in concentration levels,more enriched in the fine particulate matter PM_(2.5). |
