国内外烤烟烟气焦油、7种代表性有害成分及烟碱释放量对比分析研究

摘要

选取国内代表性烟叶产区的C3F等级烟叶样品,以及国内卷烟工业企业用量较多的、与C3F等级接近的巴西、美国、津巴布韦、赞比亚和马拉维等5个我国主要烤烟进口国烟叶样品,卷制成单料烟.考察选取的进口烟叶与国产烟叶样品烟气焦油、卷烟危害性评价指数、7种代表性有害成分和烟碱释放量差异,分析了5个进口国家烤烟烟叶有害成分释放量特点.结果表明:国产C3F等级烟叶烟气的单位燃烧烟丝重量NNK和苯酚释放量均值为最低,卷烟危害性评价指数最低.%Domestic representative flue-cured tobacco of C3F grade were taken as samples,flue-cured tobacco similar to C3F grade from five major importing countries,namely Brazil,USA,Zimbabwe,Zambia and Malawi,were used to make unblended cigarettes.Differences of tar and nicotine delivery,and 7 harmful representative components per gram of cut tobacco between domestic and foreign fluecured tobacco were investigated.The characteristics of tar and nicotine delivery,and 7 harmful representative components from 5 major importing countries flue-cured tobacco were determined.Results showed that cut tobacco weight per unit of burning tobacco,and average delivery of NNK and ammonia in mainstream cigarette smoke of domestic C3F grade leaf tobacco were the lowest and hazard index was also at minimum compared with that in foreign flue-cured tobacco.
