摘要
目的研究低焦油卷烟上滤嘴通风孔不同封堵程度对其主流烟雾中一氧化碳(CO)、烟草特有亚硝胺(TSNAs)和多环芳烃(PAHs)成分释放量的影响,为正确认识抽吸低焦油卷烟的危害提供依据。方法选取国产某品牌4种低焦油含量卷烟(1、3、5和8 mg/支),以胶带缠绕方式将烟支滤嘴通风孔进行半堵和全堵,采用加拿大深度抽吸模式利用直线型吸烟机模拟吸烟过程,检测并比较滤嘴通风孔在被全堵、半堵和不堵时产生的主流烟雾中CO、烟草特有亚硝胺(NNN和NNK)和多环芳烃释放量的差异。结果国产某品牌低焦油标注量的卷烟在其滤嘴通风孔被全堵和半堵时,主流烟雾中CO、烟草特有亚硝胺和多环芳烃的释放量较不堵时有不同程度的升高。结论在实际抽吸过程中对卷烟通风孔的封堵习惯,有可能会增加烟草烟雾中有害物质的暴露,增加吸低焦油卷烟的健康风险。
Objectives To study the impacts on the main stream components of low-tar cigarette by different filter vents blockings and provide a basis for correctly understanding the adverse effects of low-tar cigarette smoking. Methods One brand of domestic low-tar cigarette with 1, 3, 5 and 8 mg tar per cigarette were selected. The smoking process was simulated on the linear smoking machine by the Canadian intense smoking method and the filter vents of cigarettes were covered by tape as full or half blocked. The mainstream particles of cigarettes were collected on filters and the components of tobacco specific nitrosamines(NNN, NNK), polycyclic aromatic hydrocarbons(PAHs) as well as carbon monoxide(CO) were analyzed. The influence on the mainstream components of low-tar cigarette by different filter vents blockings were compared. Results Either the filter vents of low-tar cigarettes were full or half blocked, the CO, NNN, NNK and PAHs release from the mainstream smoke was all higher than that of unblocked. Conclusions In actual smoking, the filter vents of cigarette usually blocked by fingers or lips. Therefore the habit of blocking may increase the exposure of hazardous substances in tobacco smoking, then increase the health risk of low-tar cigarettes smoking.
