本文对香烟及主流烟气粒相物(TPM)、~(210)Po、Cd、Pb的含量进行分析,探讨其在吸烟过程的转移情况及醋酸纤维滤嘴的滤毒效果及意义。结果表明:香烟中~(210)Po23.0±0.10mBq/支、Cd2.69±1.108μg/支、Pb7.54±3.571μg/支,无嘴香烟主流烟气~(210)Po11.4±0.80mBq/支、
In this paper, the contents of TPM, ~ (210) Po, Cd and Pb in cigarettes and mainstream tobacco smoke were analyzed, and their transfer status during smoking and the filtering effect and significance of cellulose acetate filters were discussed. The results showed that: (210) Po23.0 ± 0.10mBq / branch, Cd2.69 ± 1.108μg / branch and Pb7.54 ± 3.571μg / 0.80mBq / branch,
