两种抽吸模式下吸烟机型对卷烟主流烟气总粒相物及7种化学成分检测结果的影响

为研究不同抽吸模式下吸烟机型对卷烟主流烟气总粒相物(TPM)和7种化学成分释放量检测结果的影响,以典型的不同焦油量(1.0~13.3 mg/支)的9种烤烟型和11种混合型卷烟样品为研究对象,考察了ISO和加拿大深度抽吸(HCI)模式下直线型(L)和转盘型(R)吸烟机对卷烟主流烟气总粒相物(TPM)和一氧化碳(CO)、4-(N-甲基-N-亚硝氨基)-1-(3-吡啶基)-1-丁酮(NNK)、苯并a]芘(Ba]P)、巴豆醛、苯酚、氰化氢(HCN)、氨(NH₃)释放量测试结果的影响。结果表明:①HCI抽吸模式下两种吸烟机型测试结果的一致性弱于ISO抽吸模式; TPM、巴豆醛和HCN在HCI抽吸模式下两种吸烟机型测试结果的差异明显。②两种抽吸模式下卷烟主流烟气NNK、Ba]P和苯酚重复检测结果标准偏差(SD,n=5)与检测水平均值(m)的相关性总体上较CO、巴豆醛、HCN和NH₃高,但HCI抽吸模式下检测结果SD与检测水平m的相关性弱于ISO抽吸模式。③在两种抽吸模式下,卷烟主流烟气相关指标不同吸烟机型测试结果总体精密度差异基本一致,即R型吸烟机对于20个不同烟气释放量水平样品重复测试结果的平均变异系数(CV)大多低于L型。 

Influences of Smoking Machine Types on Determining Results of TPM and Seven Chemical Components in Mainstream Cigarette Smoke Under Two Smoking Regimes

To study the influences of linear and rotary smoking machines on the determining results of total particulate matter(TPM) and seven chemical components, CO, 4-(N-methyl-N-nitrosamino)-1-(3-pyridyl)-1-butanone(NNK), benzoa]pyrene(Ba]P), crotonaldehyde, phenol, hydrogen cyanide(HCN) and ammonia(NH₃), in mainstream cigarette smoke, nine Virginia and eleven American blended cigarettes of different tar yields(1.0-13.3 mg/cig) weretested, and the effects of the two smoking machine types on the test results were investigated under ISO and health Canada intense(HCI) smoking regimes. The results showed that: 1) The test results obtained by the two type smoking machines were more consistent under ISO smoking regime, notably, the results of TPM, crotonaldehyde and HCN differed greatly under HCI smoking regime. 2) Under the two smoking regimes, the correlations between standard deviations(n=5) and mean values for NNK, Ba]P and phenol were generally closer than those for CO, crotonaldehyde, HCN and NH₃; however those for the said seven components were closer under ISO regime than under HCI regime. 3) The precision differences between linear and rotary smoking machines were basically the same, namely in most cases, the average coefficients of variation(CV) tested by linear smoking machine, in five repeated experiments of 20 samples with different smoke yields, were higher.
