摘要

植物修复技术是利用植物修复污染场地,恢复环境和生态系统的一种很有前景的技术。有毒有机和重金属污染物污染环境是当今发达国家和发展中国家面临的主要问题之一。重金属通过与直接参与生物降解或参与普通代谢的酶相互作用来抑制氯化有机物的生物降解。由于重金属可能以多种化学和物理形式存在,因此预测重金属对共污染土壤中有机污染物生物降解的毒性作用是很棘手的。尽管还有许多有待研究的地方,但植物修复显然将在许多污染场地的稳定和修复中发挥一定作用。推动植物修复项目实施的主要因素是成本低、场地美学显著改善和生态系统恢复潜力。本文综述了几种芸苔科(芥菜科)植物对包括重金属在内的各种环境胁迫的天然耐受性,并对其在植物修复方面的潜力进行了综述。

Potential of Brassicaceae Burnett (Mustard family; Angiosperms) in Phytoremediation of Heavy Metals
Phytoremediation technology is using plants to clean up contaminated sites is a promising loom to restore the environment and ecosystem. Pollution of the environment with toxic organic and heavy metal pollutants is one of major problem facing developed and developing nations today. Heavy metals restrain biodegradation of chlorinated organics by interacting with enzymes directly concerned in biodegradation or those involved in common metabolism. Prophecy of heavy metal toxicity effects on organic pollutant biodegradation in co-contaminated soil is tricky since heavy metals may be present in a variety of chemical and physical forms. Even if much remains to be studied, phytoremediation will clearly play some role in the stabilization and remediation of many contaminated sites. The main factor driving the execution of phytoremediation projects are low costs with considerable improvements in site aesthetics and the potential for ecosystem restoration. In this review, the potential and various aspects of few Brassicaceae (Mustard family) members in phytoremediation have been discussed due to their well known natural tolerant against various environmental stresses including heavy metals.
