| Abstract: | Metal concentrations were measured in different size airborne particles collected near two expressways with different traffic densities from April 2009 to June 2009.The pollution characterization and distribution mode of Zn,Pb,Mn,Cu,Cd,Sb in airborne particles were studied to discuss the influence of traffic volume,particle size,weather and distance.The results show that Zn concentration in airborne particles was the highest,followed by Pb,Mn,Cu,Cd,and Sb concentration was the lowest.The metal concentration was highly dependent on traffic volume,indicating that traffic was the main source of these metals.The high concentrations of Zn and Mn in PM10(possibly originated from gas exhaust) and 10 μm
