Abstract

Environmental contamination due to heavy metals (HMs) is of serious ecotoxicological concern worldwide because of their increasing use at industries. Due to non-biodegradable and persistent nature, HMs cause serious soil/water pollution and severe health hazards in living beings upon exposure. HMs can be genotoxic, carcinogenic, mutagenic, and teratogenic in nature even at low concentration. They may also act as endocrine disruptors and induce developmental as well as neurological disorders, and thus, their removal from our natural environment is crucial for the rehabilitation of contaminated sites. To cope with HM pollution, phytoremediation has emerged as a low-cost and eco-sustainable solution to conventional physicochemical cleanup methods that require high capital investment and labor alter soil properties and disturb soil microflora. Phytoremediation is a green technology wherein plants and associated microbes are used to remediate HM-contaminated sites to safeguard the environment and protect public health. Hence, in view of the above, the present paper aims to examine the feasibility of phytoremediation as a sustainable remediation technology for the management of metal-contaminated sites. Therefore, this paper provides an in-depth review on both the conventional and novel phytoremediation approaches; evaluates their efficacy to remove toxic metals from our natural environment; explores current scientific progresses, field experiences, and sustainability issues; and revises world over trends in phytoremediation research for its wider recognition and public acceptance as a sustainable remediation technology for the management of contaminated sites in the twenty-first century.

重金属污染场地的植物修复:生态环境问题、实地研究、可持续性问题和未来展望。
由于重金属在工业中的使用日益增加,环境污染已成为全球范围内严重的生态毒理学问题。由于其不可生物降解和持久性,接触后会造成严重的土壤/水体污染和严重的生物健康危害。即使在低浓度下,HMs也具有遗传毒性、致癌性、诱变性和致畸性。它们还可能作为内分泌干扰物,诱发发育和神经紊乱,因此,将它们从我们的自然环境中清除,对于污染场所的恢复至关重要。为了应对HM污染,植物修复已经成为一种低成本和生态可持续的解决方案,传统的物理化学清理方法需要高资金投入和劳动力,改变土壤性质和扰乱土壤微生物区系。植物修复是一种利用植物和相关微生物修复污染场地以保护环境和公众健康的绿色技术。因此,鉴于上述情况,本文旨在探讨植物修复作为金属污染场地管理的可持续修复技术的可行性。因此,本文对传统的植物修复方法和新的植物修复方法进行了深入的综述;评估它们从自然环境中去除有毒金属的功效;探索当前的科学进展、实地经验和可持续性问题;并修订了世界范围内植物修复研究的趋势,使其作为二十一世纪污染场地管理的可持续修复技术得到更广泛的认可和公众接受。
