摘要
重金属是一类重要的环境污染物,过量的重金属会对植物产生毒害,但某些植物可形成特定的抗性机制,以适应环境的变化。对过量重金属对植物的毒害作用以及植物对重金属抗性的机理进行了综述,并阐述了植物修复重金属污染的方式及其研究领域。
Heavy metals are important environmental pollutants,and excessive heavy metals are toxic to plants. In order to adapt environment, some kinds of plants form resistance mechanism to defending themselves against heavy metals poisoning. This paper surveyed heavy metal toxicity of plants and the corresponding toxicity mechanism and summarized the resistance mechanism of plants. The author also put forward some suggestions on their utilization on the phyto-remediation of heavy metal pollution.
