有机污染环境的植物修复研究进展

摘要/Abstract

摘要： 分析了近年来国内外的文献资料,对有机污染物污染环境的植物修复研究进展作了综述.植物能通过根系从环境中吸收和积累PCBs、PAHs等有机污染物,并将吸收的TNT、TCE及有机农药降解为高极性产物、水和CO₂;另一方面植物根际可促进有机污染物的根际生物吸收与代谢,使植物对有机污染环境的修复效果更明显.文中探讨了有机污染环境的植物修复技术的优势、问题与未来的研究.

Abstract: Plants can take up and accumulate most persistant chemicals such as PCBs and PAHs by roots. Some chemicals such as TNT, TCE, and most organic pesticides can be phytodegraded into polar metabolites, or assimilated to CO₂ and water by some plants. On the other hand, more microorganisms in rhizosphere can enhance the degradation rate of organic contaminants in environment. The benefits and some issues on phytoremediation are also discussed.

Key words: Organic contaminants, Plant uptake, Ecotoxicology, Phytoremediation, root system distribution, straw amendment, water stress, straw amendment approach
