摘　　要：研究发现,密闭室内吸烟燃烧产生的细颗粒物远大于自由燃烧。国产高档品牌香烟燃烧稳定时的颗粒物浓度小于低档品牌,国外香烟高档品牌与低档品牌之间无显著差别。香烟燃烧的室内PM_(2.5)逐时散发浓度呈指数规律增长。AUCPM_(2.5)运用PM_(2.5)散发曲线对燃烧时间的积分模型,综合考虑PM_(2.5)散发强度和燃烧时间两个因素,是一种评估二手烟暴露水平的合理方法。国外品牌香烟烟雾潜在暴露水平与品牌档级有关,而国产品牌香烟烟雾潜在暴露水平与品牌档级无关。The research showed that the smoking resulted in a sharper rise of fine particulate matter in closed indoor environment,compared with smoldering method. China＇s domestic high-grade cigarette brands produced lower stable particle concentrations than low-grade brands,while there was no significant difference between foreign high-grade brands and lowgrade brands. Both domestic and foreign cigarette brands displayed exponential growth for PM2.5 emission concentrations. The mathematical integration model of AUCPM2.5 using the PM2.5 emission curve for combustion,considers PM2.5 emission intensity and combustion time synthetically. Therefore,this method has the ability to assess potential secondhand smoke exposure. The research showed that foreign brands displayed smoke potential exposure levels proportional to the brand grade,whereas China＇s domestic brands did not.
