摘要
For discussing and evaluating the possible contribution to atmospheric pollution in the process of utilizing mineral resources as well as which has an influence to the accumulation of heavy metals in the soil, the pollution characteristics and sources of Cd element in the dust fall were evaluated in the typical mining city Tongling. 17 dustfall samples in different function zones were collected and analyzed the Cd concentrations by GFAAS. The method of copper enrichment factors (EF) were used to distinguish the possible pollution source. The result shows that the average of Cd concentration in the dustfall is 16.44 μg/g and the average of copper EF is 78.8. Cd pollution in the dustfall is serious and the central areas of pollution are around the mining and smelting factories. The mining and smelting of Cd ores are the primary pollution sources for the Cd pollution in the dustfall in Tongling. The deposition flux of Cd from the dust fall to the soil is 1.84 mg/(m2·a), which is obviously higher than its in Ma’anshan City, Hefei.
