摘要：

该文通过自行设计的在线捕集稀释装置采集烟气气溶胶，采用单颗粒气溶胶质谱仪（SPAMS）测定不同烟草制品主流烟气气溶胶中粒状物的粒径分布和含特定成分的粒状物数浓度随粒径的变化规律。结果表明三种烟草制品烟气气溶胶粒相物粒径的尺寸在0.15 μm到0.6 μm之间服从正态分布规律，且在0.3 ~0.45 μm范围内分布最为集中。三种烟草制品中含有芳香烃、有机碳和烟碱成分的粒状物占有较高比例，且不同类型的化合物在不同粒径气溶胶中呈现的分布趋势大致相同。含有特征化合物烟碱的粒状物呈现出传统卷烟<电子烟<加热不燃烧卷烟的总体趋势。致癌或促癌的化合物，包括芳香烃和重金属在传统卷烟、电子烟和加热不燃烧卷烟烟气气溶胶中的相对含量呈现逐渐增加的趋势。该文成果有助于研究烟草制品的烟气产生方式和产生条件对烟气气溶胶粒状物粒径和成分的分布规律影响。

Abstract: In this paper, the particle size distribution and the variation of particle number concentration with particle size in the mainstream smoke aerosol of traditional cigarette, electronic cigarette and heated non combustible cigarette were measured by single particle aerosol mass spectrometer (SPAMS) with a self-designed on-line capture dilution device for smoke aerosol. The results showed that the particle size of aerosol phase in the smoke of three tobacco products were mainly distributed at 0.15 μm to 0.6 μm obeying the normal distribution law, and mostly distributed in the range of 0.3-0.45 μm. The particulate matter containing aromatic hydrocarbons, organic carbon and saline alkali in the three tobacco products accounts for a high proportion, and the distribution trend of different types of compounds in aerosols with different particle sizes was roughly the same, but the particulate matter containing characteristic compound nicotine showed the distribution law of traditional cigarette < electronic cigarette < electric heating non combustion cigarette. The relative content of carcinogenic or cancer promoting compounds, including aromatic hydrocarbons and heavy metals, in the aerosol of traditional cigarettes, electronic cigarettes and heated non burning cigarettes showed a gradually increasing trend. The results of this paper are helpful to study the effects of tobacco core materials, flue gas generation methods and conditions on the particle size and composition distribution of smoke aerosol particles.
