重金属污染土壤的植物修复研究现状

植物修复是利用植物吸收、降解、挥发、根滤、稳定等作用机理,达到去除土壤、水体中污染物,或使污染物固定以减轻其危害性,或使污染物转化为毒性较低化学形态的现场治理技术。植物修复对于重金属污染土壤的治理修复具有重要意义。已有研究在累积与超累积植物的寻找筛选、植物对重金属等有害物的耐毒和解毒机理、植物修复现场环境调控及根际处理技术等方面取得了大量成果。

Research Advance on the Phytoremediation of Heavy Metal Contaminated Soil

Phytoremediation is a spot of environmental of technology that uses phytoextraction,phytodegradation,phytovolatilization,rhizofitration and phytostabilization to remove pollutants from soil and water or make contaminators fixed to alleviate its harmfulness,or translate contaminators into chemistry shape of less poisonousness.The environmental renewal of phytoremediation in the heavy metal pollutants is an important meaning.It had researched to get a great deal of fruits in the investigation,screeness of hyperaccumulator,Meanwhile,the antitoxic and detoxification of mechanism and spot environment of phytoremediation in the heavy metal.
