摘要
为降低卷烟危害性,考察了卷烟纸、接装纸、成型纸透气度对卷烟燃烧温度和卷烟主流烟气中7种有害成分(CO,HCN,NNK,NH3,B[a]P,苯酚和巴豆醛)及焦油释放量的影响,并研究了卷烟总通风率对主流烟气中7种有害成分释放量及卷烟危害性指数的影响规律。结果表明:①随着卷烟纸和接装纸透气度的增加,卷烟燃烧温度升高,卷烟主流烟气中除NNK外其他6种有害成分的释放量、焦油量及危害性指数均降低;②成型纸透气度的变化对卷烟燃烧温度及烟气有害成分释放量的影响不规律;③卷烟总通风率增加,卷烟主流烟气中多数有害成分释放量、焦油量及危害性指数有不同程度的降低。适当增加卷烟纸、接装纸的透气度,提高卷烟总通风率,可在一定程度上调控卷烟燃烧温度,降低卷烟烟气中有害成分释放量,从而降低卷烟的危害性指数。
In order to reduce the harm of smoking, the effects of air permeability of cigarette paper, tipping paper and plug wrapper on the burning temperature of cigarette and deliveries of tar and seven harmful components （including CO, HCN, NNK, NH3, B[a]P, phenol, and crotonaldehyde） in mainstream cigarette smoke （MCS） were investigated, and the effects of total ventilation rate of cigarette on the deliveries of the harmful components mentioned above in MCS and hazard index of cigarette were also studied. The results showed that： 1） With the increase of air permeability of cigarette paper and tipping paper, the burning temperature of cigarette rose,while the deliveries of tar and the harmful components （except NNK） and cigarette hazard index decreased. 2） With the change of air permeability of plug wrapper, cigarette burning temperature and the deliveries of harmful components in MCS did not change regularly. 3） With the increase of total ventilation rate of cigarette, the deliveries of tar and most harmful components in MCS and cigarette hazard index decreased to different extents. It was concluded that properly raising the air permeability of cigarette paper and tipping paper and the total ventilation rate of cigarette could control cigarette burning temperature, the deliveries of harmful components in MCS and the hazard index of cigarette to a certain extent.
