两种抽吸模式下卷烟烟气有害成分释放量与滤嘴通风率的关系

为了解不同抽吸模式下卷烟烟气有害成分释放量与滤嘴通风率的关系,考察了ISO和加拿大卫生部深度(HCI)两种抽吸模式下主流烟气中烟碱及乙醛、丙烯醛、苯、苯并a]芘、1,3-丁二烯、一氧化碳(CO)、甲醛、N-亚硝基降烟碱(NNN)、4-(N-甲基-N-亚硝氨基)-1-(3-吡啶基)-1-丁酮(NNK)、苯酚、巴豆醛、氢氰酸(HCN)和氨等13种有害成分的释放量与滤嘴通风率的相关关系,并进一步探讨了单位烟碱有害成分释放量与滤嘴通风率的相关性。结果表明:①在ISO抽吸模式下,除NNN、NNK外,其他有害成分的释放量与滤嘴通风率负相关;甲醛和巴豆醛的单位烟碱释放量与滤嘴通风率负相关,乙醛、CO、苯并a]芘和氨的单位烟碱释放量与滤嘴通风正相关。②在HCI抽吸模式下,甲醛、巴豆醛、苯并a]芘、苯酚和烟碱的释放量与滤嘴通风率负相关,HCN释放量与滤嘴通风率正相关,其余有害成分的释放量与滤嘴通风无显著相关性;乙醛、丙烯醛、巴豆醛、CO、HCN和氨的单位烟碱释放量与滤嘴通风率正相关。 

Relationships Between Filter Ventilation Rate and Deliveries of Harmful Components in Mainstream Cigarette Smoke Under ISO and HCI Smoking Regimes

To find out the relationships between filter ventilation rate and the deliveries of harmful components in mainstream cigarette smoke under different smoking regimes,the correlations between filter ventilation rate and the deliveries of nicotine and 13 harmful components(acetaldehyde,acrolein,benzene,benzoa]pyrene,1,3-butadiene,CO,formaldehyde,NNN,NNK,phenol,crotonaldehyde,HCN and NH₃) in mainstream cigarette smoke under ISO and Health Canada intensive(HCI) smoking regimes were investigated,and the correlations between filter ventilation rate and the deliveries of harmful components per unit nicotine yield were analyzed as well.The results showed that:1) Under ISO smoking regime,filter ventilation rate negatively correlated to the deliveries of harmful components(excluding NNN and NNK);filter ventilation rate negatively correlated to the deliveries of formaldehyde and crotonaldehyde per unit nicotine yield,while positively correlated to the deliveries of acetaldehyde,CO,benzoa]pyrene and NH₃ per unit nicotine yield.2) Under HCI smoking regime,filter ventilation rate negatively correlated to the deliveries of formaldehyde,crotonaldehyde,benzoa]pyrene,phenol and nicotine,while positively correlated to the delivery of HCN,there was no significant correlation between filter ventilation rate and the deliveries of the other harmful components.The deliveries of acetaldehyde,acrolein,crotonaldehyde,CO,HCN and NH₃ per unit nicotine yield also positively correlated to filter ventilation rate.
