基于土壤重金属污染的植物冶炼生态修复技术分析及应用前景展望

Analysis and application prospect of ecological remediation technology of phytomining based on soil heavy metal pollution.

随着社会的快速发展,环境问题被越来越多的人关注,土壤重金属污染问题也日益成为环境学家研究的热点。土壤中的重金属直接影响了作物的质量,并且威胁着人们的身体健康。植物冶炼是利用超富集植物修复重金属污染的土壤,并将超富集植物体内富集的重金属加以回收利用的技术。通过介绍植物冶炼金属的超富集机制以及影响因素,概述了植物冶炼不同金属的研究现状。除此之外,还分析了植物冶炼的经济效益、优缺点及其发展前景。目前,植物冶炼的相关研究还处于不成熟阶段,较为系统地总结了植物冶炼相关研究的同时,还为植物冶炼后续的深入研究提供了理论支撑。

With the rapid development of society,more and more attention has been paid to environmental issues,and soil heavy metal pollution has become a hot topic for environmentalists.The excessive heavy metals in soil will have a negative impact on crop quality and human health.Phytomining is a technology that remediation of soil contaminated by heavy metals by hyperaccumulators and recovery of heavy metals from hyperaccumulators.This paper introduces the mechanism of metal hyperaccumulation and the factors affecting phytomining,and summarizes the research status of different metals in phytomining.In addition,the economic benefits,advantages and disadvantages of phytomining and its development prospects are also analyzed.At present,the relevant research of phytomining is still in the immature stage.This paper not only systematically summarizes the relevant research of phytomining,but also provides theoretical support for the further research of phytomining.
