| 摘 要： | 为研究"一带一路"国际合作高峰论坛在京召开期间北京市典型城区环境空气中挥发性有机物(VOCs)的污染特征及有毒有害VOCs的健康风险,本研究于2017年5月1—17日,在北京市典型城区利用Airmo VOC在线分析仪进行了观测研究.结果表明,整个观测期间总VOCs质量浓度日均值为29.99μg·m~(-3);空气质量保障期间(5月6—15日),大气中VOCs的浓度低于未采取控制措施的其它阶段,沙尘阶段VOCs浓度由于受到风速和气团传输影响出现最低值;各类VOCs的质量浓度在交通早高峰出现高值.PMF来源解析表明,移动源尾气排放(37.62%)、溶剂使用源(33.25%)、油气挥发源(16.39%)和天然气燃烧源(12.74%)的排放是北京市"一带一路"会议期间环境空气中VOCs的主要来源.化学活性分析表明,芳香烃和烯烃对臭氧生成潜势贡献的占比最多,需要重点控制的VOCs物种为间对二甲苯、甲苯和丙烯.健康风险评价结果表明,研究区整个观测期间及各阶段的苯和1,2-二氯乙烷均存在潜在的致癌风险,14种有毒有害VOCs(包括苯和1,2-二氯乙烷)不存在非致癌风险.
