Abstract超细颗粒物(Ultrafine Particles,UFPs)能够进入人体肺泡组织进而危害人体健康,为了解香烟侧流烟中UFPs数浓度和表面积浓度释放及衰减特性,结合环境舱和现场实验结果对不同品牌香烟颗粒进行了分析.结果表明:燃烧过程中UFPs数浓度和表面积浓度峰值粒径分别为47.5~66.3 nm和85.6~100.5 nm,衰减2 h后,数浓度和表面积浓度峰值粒径仍小于200 nm;不同品牌香烟侧流烟中UFPs数浓度和表面积浓度释放速率分别为4.22×1012~5.23×1012个·min-1和5.95×1010~6.90×1010 μm2·min-1,根据该释放速率模拟得到的不同换气率条件下UFPs数浓度衰减趋势与实验结果相符;通风和实验环境均会影响UFPs的衰减速率,随着换气率由0.7次·h-1增至7次·h-1,侧流烟中UFPs的衰减时间由3 h降低至40 min,吸附作用的存在亦会加快UFPs的衰减速率.
