摘要
持久性有机污染物(POPs)具有环境稳定性、蓄积性等特点。在城市地表径流中,其迁移能力与径流中的颗粒物的性质与POPs本身性质、土地利用情况、排水条件、管理方式和降水条件等因素密切相关。针对国内外的研究结果总结了影响POPs在城市地表径流迁移中的受影响因素,分析了不同径流粒子的影响情况、城市绿地净化作用、管理方式以及降水过程对POPs的迁移影响。
Persistent organic pollutants （POPs）are stable by nature and could be accumulated around.POPs migration ability holds close relation to the characters of particulates,the characters of POPs,the utilization situation of land,the drainage condition,the ways of administration and the precipitation condition.Aiming at the research results at home and abroad,affecting factors of the POPs migration ability in urban runoff have been summerized,The foregoing factors have also been analyzed with the effects of the particulates distict in kind,the purification by green area,the administrative mode and the process of precipitation to the POPs migration in urban runoff.
