持久性有机污染物的根际修复及其研究方法
RHIZOSPHERE REMEDIATION FROM PERSISTENT ORGANIC POLLUTANTS AND RESEARCH APPROACHES
【摘要】 根际是具有特殊性质的土壤微生态环境,对土壤中持久性有机污染物的行为及生物修复具有重要作用。本文从微生物降解、植物过程、非生物降解、土壤吸附、挥发、淋溶等方面归纳了有机污染物根际修复的研究进展,并从细胞培养、添加根系分泌物或根系残留物、挥发污染物收集和残留态污染物测定等方面综述了有机污染物根际行为的研究方法及其优缺点。
【Abstract】 Rhizosphere is a soil micro-eco-environment with properties different from non-rhizospheric soil and has an important effect on behavior of persistent organic pollutants in the soil and bio-remediation. Progresses have been made in research on rhizosphere remediation from persistent organic pollutants. From the angles of microbial degradation, plant process, non-biological degradation, soil adsorption, volatilization and leaching, the progresses in the research were summed up and approaches to the study on behavior of the persistent organic pollutants in the rhizosphere and their advantages and disadvantages reviewed, covering cell cultivation, addition of root exudates or debris to soil, collection of volatile contaminants and determination of residue contaminants.
