对雪茄烟、卷烟和烟斗烟主流烟气中苯、苯并（a）芘（BaP）和铅进行了采样，以评价其潜在的健康意义。参考香烟的结果与公布的值一致，为所采用的方法提供了支持。苯和苯并（a）芘的排放量（以每克烟草的排放量表示）在所有评估产品中相似;对于苯，雪茄烟、RYO香烟和烟斗烟草的平均值为156 ± 100。52，68 .+-. 11，242 .+-。126 μ g/g。BaP的平均值为42 ± 0.01。7和48 .+-. 4 ng/g雪茄和RYO香烟烟草。在所有情况下，铅值均低于可靠定量限。喷烟中的平均苯浓度范围为1 - 2 × 10 - 4。对于雪茄、RYO香烟和烟斗烟草为105 μ g/m3。对于BaP，雪茄和RYO香烟烟草的喷烟浓度平均为约60 μ g/m3。结果表明，吸雪茄、烟斗或RYO香烟导致的潜在暴露超过了加州65号提案规定的苯和BaP无重大风险水平。这些烟草产品在美国加州出售时，现在必须附有健康危害警告。我们建议将此作为国家政策。
Benzene, benzo(a) pyrene (BaP), and lead in mainstream smoke from cigars, roll-your-own (RYO) cigarette and pipe tobaccos were sampled to evaluate their potential health significance. Results with reference cigarettes were consistent with published values, providing support for the methodology employed. The emission of benzene and BaP, expressed as mass emitted per gram of tobacco consumed, were similar for all products evaluated; for benzene, the mean values for cigars, RYO cigarette and pipe tobaccos were 156 .+-. 52, 68 .+-. 11, and 242 .+-. 126 .mu.g/g, respectively. Mean values for BaP were 42 .+-. 7 and 48 .+-. 4 ng/g cigars and RYO cigarette tobacco, respectively. Lead values were below the limit of reliable quantitation in all cases. The mean benzene concentration in a puff ranged from 1 to 2 .times. 105 .mu.g/m3 for cigars, RYO cigarette and pipe tobaccos. For BaP, the puff concentration averaged about 60 .mu.g/m3 for cigars and RYO cigarette tobacco. The results suggest that smoking cigars, pipes or RYO cigarettes leads to potential exposures which exceed the No Significant Risk levels of benzene and BaP set pursuant to California''s Proposition 65. These tobacco products are now required to bear a health hazard warning when sold in California (USA). We recommend that this be adopted as national policy.
