Abstract

Atmospheric depositions are the main sources of soil Cadmium(Cd) in mine lot and other industrial location, Cd accumulated in soils could have direct and indirect impacts on crops, lead to health risks as consequences. According to studies, Cd flux of atmospheric deposition showed a clear feature of spatiotemporal variation, such as its in mining area > industrial area > suburb > rural area; rainy season > dry season, dry deposition was winter spring > summer autumn; The studies also displayed much higher Cd accumulation rate in soils as affected by coal combustion, road traffic, and soil particles as well. We should pay more attention on atmospheric deposition and soil quality monitoring in the future, for Cd pollution control and environment management.
