摘要: Abstract Size distributions and characteristics of atmospheric inorganic particles at two different monitoring sites were statistically compared in order to survey site-specific original sources the particulate constituents. The average concentration difference fine coarse between was, respectively, 1.4 4.7 μg/m 3 , Fe, Mn, Zn Pb significantly high heavy traffic-flow site. Coarse form a closely related cluster group but Mn belongs another independent together with Fe. Comparative study for Zn/Pb ratio possibly suggested that regional differences derived from road dust components this might be caused essentially by tire wears previous lead additives, respectively. On contrary, Fe commonly directly affected industrial such as iron–steel factories close
