Abstract

We evaluated the benzo[a]pyrene (BaP) content in the smoke from 35 brands of Canadian cigarettes and 5 brands of Canadian tobaccos for roll-your-own cigarettes. For the cigarettes, mean values of BaP ranged from 3.36 ng to 28.39 ng per cigarette, roughly in proportion with declared tar values. The relationship between declared tar and yields of BaP, however, does not allow accurate prediction of one from the other. For the tobaccos, mean BaP values ranged from 22.92 ng to 26.27 ng (average, 24.7 ng) per cigarette. The implications of these findings are discussed with respect to overall exposure.

摘要

我们评估了35个加拿大香烟品牌以及5个用于手卷烟的加拿大烟草品牌所产生烟雾中的苯并[a]芘(BaP)含量。对于香烟而言,每支香烟中BaP的平均值在3.36纳克至28.39纳克之间,大致与所宣称的焦油含量值成比例。然而,所宣称的焦油含量与BaP产量之间的关系并不允许由其中一个准确预测另一个。对于烟草而言,每支香烟中BaP的平均值在22.92纳克至26.27纳克之间(平均为24.7纳克)。我们针对总体暴露情况讨论了这些研究结果的影响。
