接装纸对卷烟烟气焦油及7种有害成分的影响

Influences of Tipping Paper on Tar and 7 Harmful Components in Cigarette Smoke

为了降低吸烟的危害性,考察了三种不同接装纸(静电打孔、激光打孔和自然透气接装纸)对卷烟主流烟气中焦油、7种有害成分(CO,HCN,NNK,NH3,B[a]P,苯酚和巴豆醛)及危害性指数的影响。结果表明:①在相同焦油水平时,自然透气接装纸卷烟具有较低的滤嘴通风率;②在相同滤嘴通风率下,相对静电打孔、激光打孔接装纸卷烟,自然透气接装纸卷烟具有较低的焦油、CO、HCN、NNK、B[a]P和巴豆醛释放量,以及CO/焦油比值;③在相同滤嘴通风率下,三种接装纸卷烟烟气中苯酚和NH3的释放量差别不明显;④在相同滤嘴通风率下,自然透气接装纸卷烟的危害性指数较低。自然透气接装纸具有较好的降焦减害性能,可用于低危害卷烟的开发。

In order to reduce the harm of cigarette smoking, the effects of 3 kinds of tipping paper （electrostatic perforated, laser perforated and natural porous tipping paper） on the deliveries of tar and 7 harmful components （CO, HCN, NNK, NH3, B[a]P, phenol and crotonaldehyde） in mainstream cigarette smoke and the hazard index of cigarette were determined. The results showed that： 1） At the same tar level, the filter ventilation rate of cigarette with natural porous tipping paper was lower than those with perforated tipping paper. 2） At the same filter ventilation rate, the deliveries of tar, CO, HCN, NNK, B[a]P and crotonaldehyde, and the CO/tar ratio of cigarette with natural porous tipping paper were lower than those with perforated tipping paper. 3） The deliveries of NH3 and phenol had no significant difference among the cigarette samples mentioned above. 4） The hazard index of cigarette with natural porous tipping paper was lower at the same filter ventilation rate. It was concluded that natural porous tipping paper had good performance for reducing tar and harmful components in cigarette smoke and could be applied in the development of less harmful cigarettes.
