Phytoremediation is an emerging technology that uses plants to clean up pollutants (metals and organics) from the environment. Within this field of phytoremediation, the utilization of plants to transport and concentrate metals from the soil into the harvestable parts of roots and above-ground shoots is usually called phytoextraction. Most traditional remediation methods do not provide acceptable solutions for the removal of metals from soils. By contrast, phytoextraction of metals is a cost-effective approach that uses metal-accumulating plants to clean up these soils. Subsequently, the harvestable parts, rich in accumulated metals, can be easily and safely processed by drying, ashing or composting. Some extracted metals can also be reclaimed from the ash, generating recycling revenues. Phytoextraction appears a very promising technology for the removal of metal pollutants from the environment and may be, at present, approaching commercialization.
植物修复是一项新兴技术，它利用植物清除环境中的污染物（金属和有机物）。在植物修复领域内，利用植物将土壤中的金属运输并富集到可收获的根部和地上茎部通常被称为植物提取。大多数传统修复方法无法为从土壤中去除金属提供可接受的解决方案。相比之下，金属植物提取是一种经济高效的方法，它利用能积累金属的植物来清理这些土壤。随后，富含积累金属的可收获部分可以通过干燥、灰化或堆肥轻松且安全地进行处理。一些提取出的金属也可以从灰烬中回收，产生回收收益。植物提取似乎是一种从环境中去除金属污染物的非常有前景的技术，目前可能正接近商业化阶段。
