为开发低危害卷烟,测定了国内外30个不同品牌卷烟样品卷烟纸和接装纸的透气度、滤嘴长度、烟丝结构、烟气焦油及7种烟气有害成分,即CO,HCN,NH3,NNK,苯并[a]芘(BaP),苯酚,巴豆醛的释放量,计算其危害性指数,比较了不同类型卷烟烟气危害性指数的差异.结果表明:国产卷烟样品的危害性指数低于进口卷烟样品；混合型卷烟样品的危害性指数高于烤烟型卷烟样品；国产混合型卷烟样品的危害性指数略低于进口烤烟型卷烟样品；再造烟叶、晾晒烟叶的使用比例对卷烟危害性指数有较大影响.%In order to develop a cigarette which is less hazardous, the permeability of cigarette paper and tipping paper, filter length, cut tobacco composition, deliveries of tar and seven harmful cigarette smoke components, including CO, HCN, NNK, NH3, benzo[a]pyrene, phenol and crotonaldehyde, of thirty domestic and imported cigarette samples were analyzed, the hazard indices (HIs) of these samples were calculated and compared. The results showed that: 1) Of the same cigarette type, the HIs of domestic cigarette samples were lower than those of imported ones. 2) For all domestic and imported cigarette samples, the HIs of blended type were higher than those of Virginia type. 3) The HIs of domestic blended type cigarette samples were slightly lower than those of imported Virginia type. 4) The HIs of cigarette were affected by the percentages of reconstituted tobacco, air-cured or sun-cured tobacco in cigarette blends greatly.
