The Study On Dust Geochemical Characteristics In Pengzhou City Of SiChuan Province

The dust suppression is a kind of particles which fall on the ground with its own gravitation. Its diameter was more than 10μm and less than 100μm. It is dose harm for soil, water, vegetables and human being. This thesis make the detailed study of dust fall geochemical characteristic with the aim to find out the content character, the temporal and spatial distribution and source apportionment as As,Cd et al in Pengzhou Sichuan. There were not only strong theoretical significance but provide the basic data for the environmental department.The content character and the temporal-spatial distribution have little difficult in main road, but significantly different in downtown and outskirt and varing in four city zone. As,Pb,Zn are main contaminant elements.In this paper, the PengZhou city samples collection in 2002 was taken as the study target. Enrichment Factor method and background value method were used for analysis the sources and push out the countermeasures and suggestions.
