卷烟烟气焦油量与某些代表性致癌物含量的分析

Analysis of the Tar and Some Critical Carcinogens Yields in Cigarette Smoke

摘要: 测定了不同牌号卷烟烟气焦油量与烟气中的3,4-苯并a芘、N-亚硝胺等致癌物含量。结果发现,市售不同牌号卷烟烟气焦油量与致癌物含量各不相同,而对于某一特定牌号卷烟来说,焦油量降低后,焦油中3,4-苯并a芘含量相应降低;滤嘴对这些致癌物有较高的截留效果。

Abstract: Yields of tar and some carcinogens such as benzoa pyrene(BaP)and nitrosamine (NA)of cigarette smoke in different brands were determined.The results indicated that the content of tar of cigarette smoke in each commercial brand was not obviously related to the contents of the carcinogens, that the contents of BaP in some brandswere decreased as the tar was lowered, and that the carcinogens in cigarette smoke were retained effectively by cigarette filter.
