Abstract：
Heavy metal pollution in the environment is a major concern for humans as it is non-biodegradable and can have a lot of effects on the environment, humans as well as plants. At present, a solution to this problem is suggested in terms of a new, innovative and eco-friendly technology known as phytoremediation. Bast fiber plants are typically non-edible crops that have a short life cycle. It is one of the significant crops that has attracted interest for many industrial uses because of its constant fiber supply and ease of maintenance. Due to its low maintenance requirements with minimum economic investment, bast fiber plants have been widely used in phytoremediation. Nevertheless, these plants have the ability to extract metals from the soil through their deep roots, combined with their commercial prospects, making them an ideal candidate as a profit-yielding crop for phytoremediation purposes. Therefore, a comprehensive review is needed for a better understanding of the morphology and phytoremediation mechanism of four commonly bast fiber plants, such as hemp (Cannabis sativa), kenaf (Hibiscus cannabinus), jute (Corchorus olitorius) and Flax (Linum usitatissimum). This review article summarizes the existing research on the phytoremediation potential of these plants grown in different toxic pollutants such as Lead (Pb), Cadmium (Cd) and Zinc (Zn). This work also discusses several aids including natural and chemical amendments to improve phytoremediation. The role of these amendments in the bioavailability of contaminants, their uptake, translocation and bioaccumulation, as well as their effect on plant growth and development, has been highlighted in this paper. This paper helps in identifying, comparing and addressing the recent achievements of bast fiber plants for the phytoremediation of heavy metals in contaminated soil.
摘要：
环境中的重金属污染是人类关注的主要问题，因为它是不可生物降解的，并且会对环境产生很多影响，人类和植物。目前,这个问题的解决方案是建议在一个新的方面，被称为植物修复的创新和环保技术。韧皮纤维植物通常是具有短生命周期的非可食用作物。由于其恒定的纤维供应和易于维护，它是许多工业用途引起兴趣的重要作物之一。由于其维护要求低，经济投资最小，韧皮纤维植物已广泛应用于植物修复。然而，这些植物有能力通过它们的深根从土壤中提取金属，结合他们的商业前景，使它们成为植物修复目的的理想候选作物。因此,需要进行全面的审查，以更好地了解四种常见韧皮纤维植物的形态和植物修复机制，如大麻（大麻），红麻（木薯大麻），黄麻（Corchorusolitorius）和亚麻（Linumusitatissimum）。这篇综述文章总结了在不同有毒污染物如铅（Pb）中生长的这些植物的植物修复潜力的现有研究，镉(Cd)和锌(Zn)。这项工作还讨论了几种助剂，包括天然和化学改良剂，以改善植物修复。这些修正案在污染物生物利用度方面的作用，他们的摄取，易位和生物累积，以及它们对植物生长和发育的影响，在本文中得到了强调。这篇文章有助于识别，比较和解决了韧皮纤维植物对污染土壤中重金属的植物修复的最新成就。
