| Abstract: |
| Soil remediation measures have been applied extensively in heavy metal polluted farmland in China. Because the control technology and remediation system are insufficient basing on different risk levels, it is difficult to deal with the soil pollution which has increasingly and seriously negative effects. Thus, it is necessary to integrate reasonably remediation technologies to find out a systematic method which is effective for the remediation of heavy metal polluted farmland. This study is conducted to summarize and make conclusion the characteristics of various technologies which are suitable for polluted soil remediation, including phytoremediation, agronomic measure, interplanting, soil leaching and soil passivation, etc. On this basis, we are trying to propose an integration between methodology and technology considering risk levels of pollution, physical and chemical properties of soil, technical characteristics and human activities, etc. This research provides an effective approach to technical support for the remediation and sustainable utilization of heavy metals polluted farmlands in China. |
