Farmland Soil Cadmium Pollution of In Situ Passivation Remediation Technology |
| |
| Abstract: | The authors introduced present situation of soil cadmium pollution in China and abroad and the source of cadmium in farmland, and summarized the form of cadmium in soil and its bioavailability, the concept and mechanism of in situ passivation remediation and the main types of passivation. In situ passivation remediation technology of soil cadmium pollution had many advantages, such as low investment, highefficiency, short time of repairing, easy operation and so on, it could be well applied to the soil with low or moderate pollution. In addition, the authors proposed the limitations of in situ remediation of cadmium pollution in farmland soil and improvement measures. |
