Advances in bioremediation of cadmium-contaminated soils

Cadmium not only threatens the normal growth of plants, but also causes serious harm to human health through the food chain. In order to reduce the impact of cadmium pollution on the ecological environment, contaminated soil must be treated. This paper summarizes the current situation of soil Cd pollution in China, the main areas and sources of Cd pollution. We also analyze the characteristics of soil Cd pollution, introduces and reviews the physical and chemical technology, bioremediation technology, ecological remediation and combined remediation technology currently used to treat soil Cd pollution, in order to provide scientific reference for further research in this field.
