【摘要】 为考察不同抽吸方式对卷烟主流烟气中氢氰酸(HCN)释放量的影响,采用ISO、Massachusetts和Health Canada 3种抽吸方式分别抽吸了15种市售卷烟,采用连续流动法测定了主流烟气中的HCN释放量。研究表明:与ISO方案相比,采用Massachusetts或Health Canada深度抽吸方式,HCN释放量均有显著提高;抽吸方式的改变对低焦油卷烟、高滤嘴通风率的卷烟的HCN释放量影响更为显著。更多还原

【Abstract】 Effect of smoking regime on HCN yields in mainstream cigarette smoke was studied using 15 different cigarettes smoked under three smoking regimes,i.e.ISO,Massachusetts and Health Canada,respectively.HCN yields were determined by continuous flow analyzer.Results showed that(1) HCN yields determined by Massachusetts method and Health Canada method is significantly higher than by ISO method.(2) Variance of smoking regimes resulted significant difference in low-tar cigarettes and highly ventilated filter cigarettes.更多还原
