摘要
概括了放射性污染的植物修复技术田间应用研究状况,总结分析了放射性核素的生物可利用性及超富集植物筛选等因素对田间植物修复效果的影响。推导建立了保守清除模型,估算出植物修复的数十年的修复应用时间;结合环境治理的需求,分析了放射性污染的植物修复应用前景。
The paper summarizes the state of the art in the field of pilot experiments of radiophytoremediation. The effects of radionuclide bioavailability and hyperaccumulators on phytoremediation efficiency were discussed, and time required in radiophytoremediation was simulated and evaluated according to a conservative model which was established by authors. The prospect of radiophytoremediation was discussed in terms of requirements for remediation of radionuclide contaminated environment.
