Migration and Accumulation of Cadmium in Paddy Soil

Abstract:

Soil samples were collected from a paddy field at Fulong village, Huanjiang County, and Cd concentrations in soils were determined. Soil Cd risk was evaluated using Nemerow index method. The results showed that the content of cadmium in soil layer of 0~20cm is 2 times than the level two standard values and 6 times than the background value of Huanjiang soil. In addition, the soil layer of 20~100cm in cadmium content did not exceed the national level two standard values, but is about 2 times the background value of soil in Huanjiang county. In addition, Cadmium pollution is mainly focused on the soil surface.
