摘要
地铁车站内颗粒物(PM)主要来源于列车车轮、轨道、刹车片等部件之间磨损所产生的微粒,金属氧化物占比较高,长时间暴露于地铁PM中可能会增加通勤者和工作人员的健康风险。通过大量的文献综述,介绍了地铁PM的组分特征及来源,对比了全球不同城市地铁PM的污染现状及时空分布特征,讨论了影响地铁PM浓度的主要因素,汇总了当前地铁PM的常用排除方法,最后对如何高效优化地铁空气质量提出了建议。
Particulate matter(PM)in underground subway station is mainly caused by the wear among train wheels,tracks,brake pads and other parts.The main constituent of subway PM is metal oxide.It might increase health risk for commuters and workers if exposing in subway PM for long time.By reviewing a large number of literatures,this paper introduced characteristic components and origins of subway PM,compared the current pollution situation and temporal-spatial distribution characteristics of subway PM all around the world,discussed the main factors which affected the concentration of subway PM,summarized currently-used subway PM elimination methods,and finally put forward technical suggestions on optimizing air quality in subway.
