卷烟纸对卷烟主流烟气中7种有害成分释放量的影响

Effects of Cigarette Paper on Deliveries of Seven Harmful Components in Mainstream Cigarette Smoke

为降低吸烟对人体健康的危害,考察了卷烟纸透气度、定量和助剂对主流烟气中CO等7种有害成分的影响。结果表明:①随着卷烟纸透气度的增加,卷烟主流烟气中CO,HCN,B[a]P,NH3,苯酚和卷烟危害性指数都呈降低趋势,而NNK和巴豆醛的变化不明显;②随着卷烟纸定量的增大,卷烟主流烟气中CO,HCN的释放量和卷烟危害性指数呈增大趋势,而巴豆醛,B[a]P,NNK,NH3和苯酚随卷烟纸定量的变化不显著;③不管是有机酸钾,还是有机酸钾与有机酸钠的混合物,随着其在卷烟纸中的用量增大,烟气CO,HCN,B[a]P,NH3,苯酚释放量和卷烟危害性指数也都呈降低趋势,但降低幅度都不大,NNK和巴豆醛的释放量变化不明显;④有机酸钾盐降低CO,HCN,B[a]P,NH3,苯酚释放量和卷烟危害性指数的效果优于有机酸钾钠盐混合物。适当增大卷烟纸透气度,降低卷烟纸定量,提高有机酸钾盐的用量可在一定程度上降低卷烟主流烟气中CO,HCN,B[a]P,NH3,苯酚释放量和卷烟危害性指数。

In order to reduce the harm of smoking to human health,the effects of permeability and basis weight of and additives in cigarette paper on the contents of seven harmful components in mainstream cigarette smoke were investigated.The results showed that： 1） With the increase of cigarette paper permeability,the contents of B[a]P,NH3,phenol,CO and HCN in smoke and cigarette hazard index decreased,while the contents of 4-（methylnitrosamino）-1-（3-pyridyl）-1-butanone（NNK） and crotonaldehyde changed little;2） With the increase of basis weight of cigarette paper,the CO and HCN contents in smoke,and cigarette hazard index increased,while the contents of crotonaldehyde,B[a]P,NNK,NH3 and phenol did not change significantly;3） With the increase of addition amounts of potassium carboxylate or the mixture of potassium and sodium carboxylates in cigarette paper,the contents of CO,HCN,B[a]P,NH3,and phenol in smoke and cigarette hazard index decreased slightly,while NNK and crotonaldehyde contents changed little;4） Potassium carboxylate decreased CO,HCN,B[a]P,NH3 and phenol contents,and cigarette hazard index more effectively than the mixture of potassium and sodium carboxylates.It was concluded that CO,HCN,B[a]P,NH3 and phenol and cigarette hazard index could be decreased to a certain extent by properly increasing permeability,decreasing basis weight of cigarette paper,and increasing the addition amounts of potassium carboxylate in cigarette paper.
