This review briefly elucidates the research undertaken and benefits of using aromatic plants for remediation of heavy metal polluted sites. A sustainable approach to mitigate heavy metal contamination of environment is need of the hour. Phytoremediation has emerged to be one of the most preferable choices for combating the metal pollution problem. Aromatic plants can be used for remediation of contaminated sites as they are non-food crops thus minimizing the risk of food chain contamination. Most promising aromatic plants for phytoremediation of heavy metal contaminated sites have been identified from families - Poaceae, Lamiaceae, Asteraceae, and Geraniaceae. They act as potential phytostabilisers, hyper accumulators, bio-monitors, and facultative metallophytes. Being high value economic crops, monetary benefits can be obtained by growing them in tainted areas instead of food crops. It has been observed that heavy metal stress enhances the essential oil percentage of certain aromatic crops. Research conducted on some major aromatic plants in this context has been highlighted in the present review which suggests that aromatic plants hold a great potential for phytoremediation. It has been reported that essential oil from aromatic crops is not contaminated by heavy metals significantly. Thus, aromatic plants are emerging as an ideal candidate for phytoremediation. Highlights • Aromatic plants hold a great potential for phytoremediation of heavy metal contaminated sites. • Being high value economic crops, monetary benefits can be obtained by growing them in contaminated areas instead of food crops. • Research done on some major aromatic plants in this context has been highlighted in the present review.
这篇综述简要阐述了利用芳香植物修复重金属污染场地的研究进展和益处。当前迫切需要采取可持续的方法来减轻环境中的重金属污染。植物修复作为一种应对金属污染问题的首选方法之一，已经崭露头角。芳香植物可用于污染场地的修复，因为它们是非食用作物，从而最大限度地减少食物链污染的风险。已经从禾本科、唇形科、菊科和牻牛儿苗科等科中确定了最有前途的用于修复重金属污染场地的芳香植物。它们可以作为潜在的植物稳定剂、超积累植物、生物监测器和兼性金属植物。作为高价值经济作物，在受污染地区种植它们而不是粮食作物可以获得经济利益。已经观察到重金属胁迫会增加某些芳香作物的精油百分比。本文综述强调了这方面一些主要芳香植物的研究，这表明芳香植物在植物修复方面具有巨大的潜力。据报道，芳香作物的精油受重金属污染的程度并不显著。因此，芳香植物作为植物修复的理想候选者正在出现。 亮点 • 芳香植物在修复重金属污染场地方面具有巨大的潜力。 • 作为高价值经济作物，在污染地区种植它们而不是粮食作物可以获得经济利益。 • 本文综述强调了这方面一些主要芳香植物的研究。
