Abstract

By collecting dust samples from seven different functional areas of Guiyang city, we studied the distribution pattern of the level of Zn in dusts with particle size fractions. The result showed the geometric means of Zn concentration in dusts of Guiyang was 435mg/kg. The Zn in most functional areas was primarily associated with middle particles, while the Zn in industrial area and garbage stations were primarily associated with fine particles.
