Comparing size distribution of trace elements at haze weather and the normal weather discovered that,Ca、Ti、Fe、Cr showed significant enrichment in the small size particle at the haze weather:Cu,As didn't have different at such two kind of weather conditions;Zn、Mn、Pb appeared bimodal even trimodal distribution,whose suggested that there were a long distance transmission in originations of such three metals.

对比正常天气下的金属元素的粒径分布，发现：Ca、Ti、Fe、Cr 等元素在灰霾发生时细粒径上有明显的富集： Cu、As 在两种天气条件下区别不是很大：Zn、Mn、Pb 等元素在两种天气条件下均出现双峰甚至多峰分布。由此推断 Zn、Mn、Pb 的来源中可能存在长距离传输。
