环境持久性自由基对有机污染物环境行为的影响研究进展
发布时间：2019-02-09 15:34
【摘要】：环境持久性自由基(EPFRs)作为一类新型的环境风险物质在环境中普遍存在,具有较高的反应活性和环境风险。以往研究主要关注污染物在燃烧或者高温等极端条件下EPFRs的产生机制,对更具普遍性的自然条件下产生的EPFRs的环境行为和风险关注不够。本文综述了环境介质、人工合成碳基材料以及有机污染物降解过程中EPFRs的存在和产生机制,着重论述了EPFRs对前体有机污染物环境行为的影响,以及EPFRs的存在能促进环境中共存有机污染物的降解。最后提出了EPFRs参与有机污染物的降解过程可能是理解有机污染物环境行为、风险研究中所缺失的重要环节,并对以后应注重开展的研究进行了展望。
[Abstract]:As a new class of environmental risk substances, environmental persistent free radical (EPFRs) is ubiquitous in the environment, and has high reaction activity and environmental risk. Previous studies have focused on the production mechanism of EPFRs under extreme conditions such as combustion or high temperature, but not on the environmental behavior and risk of EPFRs produced under more general natural conditions. In this paper, the existence and production mechanism of EPFRs in environmental media, synthetic carbon-based materials and organic pollutants degradation are reviewed. The effects of EPFRs on the environmental behavior of precursor organic pollutants are emphatically discussed. And the existence of EPFRs can promote the degradation of co-existing organic pollutants in the environment. Finally, it is pointed out that the involvement of EPFRs in the degradation process of organic pollutants may be an important link in understanding the environmental behavior of organic pollutants and the risk research.
