污染土壤植物修复技术及其机理研究

Phytoremediation and its mechanisms for contaminated soils

  • 摘要: 阐述了污染土壤植物修复技术消除污染物的吸收、积累、降解、抑制和转化作用的关键机制,并指出该技术存在的问题、局限性及其应用植物修复技术应注重的关键环节。研究表明植物根际对石油烃降解及抑制是这些化合物的主要损失机制,而金属的植物修复技术主要基于植物的稳定和积累作用。

     

    Abstract: This paper introduces the application efficacy of phytoremediation in hyarocarbon and meta1 contaminated soils,and discusses the key mechanisms of uptake,accumulation,degradation,inhibition and transformation of petroleum hydrocarbons and/or metals in plants.Problems.1imitations and key tache are also addressed.It is concluded that the degradation and inhibition of petroleum hydrocarbons in the rhizosphere of plants are the primary loss mechanism for these compounds,and stabilization and accumulation are the key processes for metal clean up.
