摘要
综述了加热不燃烧卷烟气溶胶的化学成分和毒理学评价及加热不燃烧状态下烟叶或烟草材料的热解情况。要点如下:(1)加热不燃烧卷烟气溶胶主要由甘油、水、烟碱和较少潜在有害物质(HPHCs)组成,其中气溶胶中挥发性成分、苯并芘、TSNAs、酚类化合物、苯乙烯等相对于传统卷烟降低80%以上。(2)加热不燃烧卷烟气溶胶生理毒性低于传统卷烟。(3)加热不燃烧状态下例如250~550℃之间,烟碱释放速率随温度升高而减慢,而二氧化碳和一氧化碳释放速率随温度升高而增快。
Research in chemical constituents and toxicological evaluation of heat-not-burn tobacco product aerosol and emission characteristics of aerosol from tobacco in heating instead of burning were reviewed.（1） Aerosol from heat-not-burn tobacco product consists mainly of glycerin, water, nicotine and lower yields of HPHCs. Volatile constituents, benzo[a]pyrene, tobacco specific nitrosamines, phenols, and styrene were 80% lower than those in traditional cigarettes.（2） Aerosol from heat-not-burn tobacco product showed lower toxicity than that of traditional cigarettes.（3） Under condition of heating not combustion state of 250～550℃, nicotine release rate slows down while carbon dioxide and carbon monoxide release rate increases with the rise of temperature.
