摘要
环境持久性自由基(environmentally persistent free radicals,EPFRs)是相对传统短寿命自由基提出的一类广泛存在于各种环境介质中并具有潜在环境风险的物质.在大气环境中,由于大气颗粒物的来源广泛、迁移性强,使得其含有的EPFRs的影响范围较广.近年来EPFRs被认为是大气污染健康风险因子而广受关注.本文主要概述大气颗粒物中EPFRs的国内外研究进展,同时总结EPFRs的来源、生成机制及环境效应,并展望了EPFRs未来的研究方向.
Environmentally persistent free radicals(EPFRs)are a class of substances with long-term potential environmental risks that are proposed in relation to traditional short-lived free radicals and exist in various environmental media.Due to the wide souce and high mobility of atmospheric particulate matter(PM),the EPFRs contained in PM have a wide range of influence.In recent years,it has been widely considered as an air pollution risk factor.This paper mainly summarizes the research progress of EPFRs in atmospheric particulates at home and abroad,summarizes the source,formation mechanism and environmental effects of EPFRs,and looks forward to the future research direction of EPFRs.
