| Abstract: | Soil mercury contamination and its remediation is one of the core issues of mercury environmental geochemistry. Physical and chemical methods for the treatment of mercury-contaminated soils have serious limitations due to the high cost, low efficiency and the secondary pollution concerns. Phytoremediation is receiving increasing attention in the light of inexpensive, efficient, and environmental and eco-friend traits. In this review, the principle of phytoremediation of mercury-contaminated soils and the application of this technique has been summarized which include the characterization of soil mercury contamination, the principle and process of phytoremediation technique, suitable plants and potential suitable plants for phytoremediation, and the enhancement measures of phytoremediation are discussed. In view of the shortcomings of the existing research, the research direction and development trend of phytoremediation of mercury contaminated soil are prospected, in order to provide scientific reference for the application and development of phytoremediation technology of mercury contaminated soil. |
