摘要:To study the contribution rate of heavy metals to the natural source of atmospheric dusts, this paper implements nine sets of experiments on the soils and dusts that are collected from Mount Guanxiangshan, Dapozi community, and Wangjianvgu village. The heavy metals contained in the 130 meshes dusts; the 35 meshes soils and the 130 meshes soils are tested. Based on these tested results, the enrichment factors of heavy metals in dusts are computed. Systematical analysis of these results shows that the contents of heavy metals in soils are relative to the type of soils as well as the sizes of grains. Besides, 130 meshes dusts and 130 meshes soils have different contents of heavy metals. Therefore, we can not use heavy metals in the 130 meshes soils to substitute the nature source of heavy metals in the atmospheric dusts. The enrichment factors of heavy metals in dusts are different from each other with the types of soils and elements, which illustrates that the contribution rates of natural source of the heavy metals in atmospheric dusts have obvious differences. Moreover, as all the enrichment factors of heavy metals in dusts are smaller than 3, the contribution rates of heavy metals nature source in atmospheric dusts should also smaller than 3. The results gotten in this paper can provide scientific evidence for the contribution rate computation of heavy metals in atmospheric dusts.
