卷烟烟气焦油量与B(a)P含量分析

Analysis on the Contents of Tar and Benzo(a) pyrene in Cigarette Smoke.

[目的 ]探讨香烟烟气焦油和苯并 (a)芘〔B(a) P〕含量的关系。 [方法 ]测定 9种市售香烟烟气焦油和 B(a) P含量 ,并测定了滤嘴对焦油中 B(a) P的吸附效果。 [结果 ]香烟烟气中焦油含量为 4.6～ 19.7mg/支 ,焦油中 B(a) P含量为 15 .7～ 2 7.1ng/支 ,滤嘴对焦油中 B(a) P的吸附率达 5 7.6 %～ 84.7%。 [结论 ]不同牌号香烟烟气中焦油含量与 B(a) P含量无相关性 ,滤嘴可吸附部分烟气焦油中的 B(a) P。

Objective]To study the relationship between the contents of tar and benzo(a) pyrene〔B(a)P〕in cigarette smoke.[Methods]The contents of tar and B(a)P were determined in 9 kinds of cigarette smoke,and adsorptive effect of filter to B(a)P in tar of smoke was determined also.[Results]The contents of tar ranged 4 6~19 7 mg/cigarette,the contents of B(a)P in tar ranged 15.7~27.1 ng/cigarette.The adsorptive rates of filter to B(a)P of tar were 57.6%~84.7%.[Conclusion]No correlation was observed between the contents of tar and B(a)P in smoke of different brands of cigarette,B(a)P in tar of smoke could be partially adsorpted by cigarette filter.
