摘要:为研究国内不同产地烟叶在同一等级、同一年限的情况下对卷烟主流烟气中7种有害成分释放量的影响,分析国内9个省份17个产地的烤烟单料烟的样品。结果表明,云南楚雄、陕西咸阳、河南洛阳烟叶总体危害性明显高于平均水平;云南昭通、河南南阳烟叶总体危害性稍高于平均水平;黑龙江烟叶的氨释放量几乎是平均水平的2倍,BaP释放量高于平均值40%以上,总体危害性指数明显高于全国水平;福建三明、湖南张家界、云南德宏烟叶总体危害性与平均值基本持平;四川凉山、河南三门峡、贵州遵义、甘肃陇南、福建南平烟叶总体危害性稍低于平均水平;湖南郴州、永州、云南宣威烟叶总体危害性明显低于平均水平。

Abstract:In order to study the effects of different domestic tobacco leaves in the same grade and same year on the release of seven harmful components in cigarette smoke,17 tobacco samples selected from 9 provinces were analyzed. The results showed that the overall dangers of tobacco in Chuxiong,Xianyang and Luoyang were significantly higher than the average level. The overall dangers of tobacco leaves in Zhaotong and He"nan Nanyang were slightly higher than the average level. The tobacco leaves from Heilongjiang province were significantly higher than average level in hazard index,especially almost twice as high as the average in ammonia and higher than the average of more than 40% in BaP. The overall hazards were basically the same as the average value in the samples from Fujian Sanming,Hu"nan Zhangjiajie and Yunnan Dehong. The hazard index of samples from Sichuan Liangshan,He"nan Sanmenxia,Guizhou Zunyi,Gansu Longnan,Fujian Nanping were slightly lower than the average level,while the samples from Hu"nan Chenzhou,Yongzhou,Yunnan Xuanwei had the overall dangers significantly lower than the average level.

卷烟在燃烧过程中释放出有超过6 000种的化学物质,其中包括大部分的致香成分和少量的有害成分。1998年,加拿大政府通过立法要求卷烟生产商定期检测卷烟主流烟气中46种有害成分的含量,并将结果公之于众,这是一个修正的hoffmann名单。2006年1月8日《烟草控制框架公约》在我国正式生效,烟草行业面临“吸烟与健康问题”的压力进一步加强。相关研究确定了表征卷烟危害性的7个定性有害成分指标,即CO,HCN,NNK,NH3,以及苯并(α)芘(Bap)、苯酚、巴豆醛,并给出了危害性指数的计算方法。因此,卷烟降焦减害一直是烟草行业研究的重要课题,从物理、化学、配方等方面展开了大量研究,投入了较多的人力和物力[1]。叶组配方设计是卷烟产品的核心,但关于单料烟的 7种有害成分释放量的研究较少。为了深入研究卷烟危害性的影响因素,分析了我国不同产地烟叶的危害性指数,以期为烟叶的种植、栽培和卷烟工业的调配提供依据,从源头降低卷烟的危害性,减少吸烟对人体的危害。
1 样品的设计与制备
以国内重点产区烟叶原料为研究对象,选取云南、贵州、四川、福建、湖南、陕西、甘肃、河南和黑龙江等9个省份17个产地烟叶原料,烟叶原料在同一等级(等级:C3F)、同一年限条件下。
单料烟样品制作参数在相同规格烟用材料、工艺加工参数及卷制工艺参数下卷制成烟支为烟支长度84.0 mm,滤嘴长度20.0 mm,圆周24.5 mm,质量0.88 g /支,卷烟纸透气度40 CU,克质量27 g/m3,烟支硬度67 g /支,無滤嘴通风,滤棒吸阻为3 300 Pa。
