| Abstract: |
| The application of biochar for Cd pollution remediation in agriculture soil is a hot topic of concern. This paper reviewed the study progress in several aspects, including the impacts of biochar on Cd bioavailability in polluted soil and Cd uptake in plants. Meanwhile, we expounded the multi-mechanism for inactivation of cadmium by biochar and discussed the influencing factors from the aspects of properties of biochar, soil and management factors. The analysis results suggested that the mechanisms for high-efficiency and sustainable inactivation performance of biochar could be realized by improving materials properties and management. Finally, we proposed that long-term location field experiments should be enhanced in this area to provide further scientific evidence for pollution remediation with biochar. |
