The Chemical Composition and Sources of PM10 in Urban Road Dust

Article Preview

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.
