Abstract: Based on kinetic principle and the Iaw of inputand output, we have studied the contarnination factors of agri-cultural Iands around a Iead and zinc metallurgical plant. Theresults showed that the main factor of Cd contaminated soilwas the organic materials such as pig gery manure. It wassuggested that earthworm be bred and the pteridophyte beplanted instead of recycling the rice straw back to the farm-Iand to reduce and control the Cd contamination.

Key words: soil, Cd contamination, clean idea
