重金属污染水体的植物修复研究现状

The Current Situation of Phytoremediation on Heavy Metal Polluted Waterbody

水体重金属污染已经成为一个日益严重的环境问题,不仅对环境造成危害,同时也威胁着人类的健康。重金属的植物修复是一种利用经过特殊筛选的重金属积累植物从土壤和水体中去除有毒重金属的低成本绿色技术。介绍了水体污染治理中植物修复的概念、原理和技术类型,指出目前研究中存在的问题和今后的研究方向。

The heavy metal pollution of water became a serious environmental problem, it was not only harmful to the environment, but also a threat to human health. Phytoremediation of metals was a cost-effective “green” technology based on the use of specially selected metal- accumulating plants to remove toxic metals from soil and water. The definition, the type of technology and the mechanism of phytoremediation were discussed. Meanwhile, the current problems and developing prospect of phytoremediation were elaborated.
