Paper Title:
The Chemical Composition and Sources of PM10 in Urban Road Dust
  Abstract

Samples of road dust were collected in Changzhi, Taiyuan and Jincheng in Shanxi Province, the characteristics of the chemical composition of fine particles (diameter ≤ 10μm)and the chemical profiles of road dust obtained from different cities were analyzed, the "double source apportion" technology was applied to identify the source of road dust . Results show that: the chemical profiles of road dust vary significantly in different regions, however, all contain a high percentage of Si, Ca, Al, TC and OC, with the highest content of Si; Road dust originates mainly from soil dust, smoke and dust from coal and cement dust, and their contributions to road dust are 50%,25% and 15% in Changzhi ,47%,26% and 20% in Taiyuan,48%,21% and 22% in Jincheng, respectively.
