Investigation of Cd contents in soils south to the Daye Smeltery revealed that farmland in that region was seriously contaminated with Cd. The Cd content of the paddy fields there was 51.5 mgCd/kg on average, with the highest reaching 99.5mgCd/kg and Pi above 3, which indicated that the paddy fields were seriously contaminated. Besides, causes of such a high contamination were investigated and on such a basis countermeasures are put forth in the paper for control of the contamination.
