抽吸模式对卷烟主流烟气主要芳香胺释放量的影响

为研究抽吸模式对卷烟主流烟气中主要芳香胺释放量的影响，在ISO、Massachusetts和Health Canada这3种抽吸模式下分别抽吸了15种市售卷烟，采用液相色谱-串联质谱（LC-MS／MS）法测定了主流烟气中4种主要芳香胺的释放量．结果表明：①混合型卷烟芳香胺释放量明显高于烤烟型卷烟；②与ISO方案相比，采用Massachusetts或Health Canada抽吸模式，卷烟烟气芳香胺的释放量均显著提高；③抽吸模式的改变对高滤嘴通风率卷烟芳香胺释放量的影响更为显著；④卷烟主流烟气中的焦油含量与芳香胺释放量呈现不明显的相关性．

Effect of smoking regime on aromatic amines yields in mainstream cigarette smoke

In order to study the effect of smoking regime on aromatic amines yields in mainstream cigarette smoke, 15 kinds of commercially available cigarette samples were smoked under three smoking regimes： ISO, Massachusetts and Health Canada methods, respectively. Then LC-MS/MS method was applied to test the released amount of four kinds of primary aromatic amines in the mainstream smoke. The results showed that： ①Blended cigarettes released significantly higher amount of aromatic amines than flue-cured counterparts; ②Compared with ISO method, the aromatic amines emission content had dramatically increased when Massachusetts method or Health Canada method was adopted; ③ Transformation of smoking regimes showed a greater impact of high filter ventilation rate cigarettes on the content of released aromatic amines;④ The tar and the emission content of aromatic amines in the mainstream smoke presented some inconspicuous correlation.
