Heavy-metal cadmium pollution in the soil has attracted more attention. The sources and hazards of cadmium in the soil,the chemical speciation and extraction methods of cadmium in the soil were briefly described in this paper,the changes of formations and the changes of physical and chemical cadmium in the soil were mainly elaborated.This paper discussed factors including pH,organic matter,temperature,oxidation reduction potential and other impact factors affecting chemical speciation of cadmium in the soil. Analyzing the influence factors in the previous experiments,the research results and the existence of omissions and problems will provide reference for the study of cadmium contamination and subsequent remediation.
