摘要
重金属污染土壤的植物修复技术被认为是一种绿色、生态友好的土壤修复技术。对植物修复的低效率、二次污染风险及高成本三个不利因素进行系统的阐述,针对上述三个缺点提出相应的对策,并对其在重金属污染土壤修复中的应用进行可行性分析。
Phytoremediation of heavy metal contaminated soils has been considered as a green and eco-friendly remediation technique.However,this technique needs significant improvements to become practically feasible.In this paper,three adverse factors of phytoremediation,pollution risk,low efficiency and high cost of remediation,were systematically discussed.Furthermore,corresponding countermeasures of improving phytoremediation efficiency aimed at the above three disadvantages were proposed.
