  • Heavy metal contamination, occurring due to both natural and anthropogenic activities, is one of the research focus throughout the world. The Ministry of Ecology and Environment (MEE) and the Ministry of Natural Resources (MNR) of the People's Republic of China issued a joint report on the current status of soil contamination in China. The report presents an overall grim situation with regard to the heavy metal pollution of China's soils. Combined earthworm-plant remediation is better than a single plant remediation and earthworm remediation. Base on literature review and analysis, this paper summarized the research status of hyperaccumulators in China and the role of earthworms in phytoremediation. The advantages and disadvantages were discussed, while its potential application was prospected,which would provide basis for carrying out earthworm-plant remediation in the future. The issues which need further study were presented, in terms of the application of earthworm-plant remediation.

Review and prospection of soil heavy metal remediation with combined earthworm-plant technology

Fund Project: Supported by the National Natural Science Foundation of China (41701564), Science and Technology Project in Suzhou(SNG201613),Natural Science Fund for Colleges and Universities in Jiangsu Province(17KJB610010)and Graduate Student Scientific Research Innovation Projects in Jiangsu Province(SJCX17_0674).

Abstract: Heavy metal contamination, occurring due to both natural and anthropogenic activities, is one of the research focus throughout the world. The Ministry of Ecology and Environment (MEE) and the Ministry of Natural Resources (MNR) of the People's Republic of China issued a joint report on the current status of soil contamination in China. The report presents an overall grim situation with regard to the heavy metal pollution of China's soils. Combined earthworm-plant remediation is better than a single plant remediation and earthworm remediation. Base on literature review and analysis, this paper summarized the research status of hyperaccumulators in China and the role of earthworms in phytoremediation. The advantages and disadvantages were discussed, while its potential application was prospected,which would provide basis for carrying out earthworm-plant remediation in the future. The issues which need further study were presented, in terms of the application of earthworm-plant remediation.
