| 摘 要： | 采用"二重源解析"技术解析了太原市的各单一源类对城市道路尘(以下简称道路尘)的贡献值和分担率;各单一源类和道路尘对城市扬尘的贡献值和分担率;同时解析了各单一源类、道路尘和城市扬尘对环境空气颗粒物的贡献值和分担率。各源类对PM10的贡献率分别是:城市扬尘,27%;道路尘,20%;土壤风沙尘,10%;煤烟尘,13%;建筑水泥尘,10%;机动车尾气尘,11%;钢铁尘,1%;其他,8%。

| Abstract: | Applying'double source apportion'technology and related atmospheric particulate data in Taiyuan City,the author successfully analyzed the contributions and ratios of individual sources to road dust,the contributions and ratios of road dust to urban raised dust,the contributions and ratios of individual sources,road dust and urban raised dust to the ambient air particulate matter as well.Ratios of PM10 came from each source type: urban raised dust 27%;road raised dust 20%;soil dust 10%;smoke and dust from co... |
