不同烟具阻留毒物效率的比较

Comparison of reductive effect on toxicants in cigarattes by various kinds of smoking sets

用卷烟烟雾多功能自动采样器连接不同烟具分别采集卷烟、烟丝燃烧后的主流烟和侧流烟的颗粒物(TPM)、分析其中焦油(Tar)、尼古丁(Nic)和苯并(a)芘[B(a)P]的含量。阻留效率是:竹筒水烟具>铜制水烟壶>旱烟具。不同材料滤嘴阻留TPM、Tar、Nic和B(a)P的效率是醋酸纤维+活性炭+纸的复合滤嘴(56.3%～67.4%)>醋酸纤维+活性炭滤嘴(48.0%～54.1%)>醋酸纤维滤嘴(28.4%～36.4%)>聚丙烯纤维滤嘴(24.5%～33.9%)。

Toxicants including Total Particulate Matter (TPM), Tar, Nicotine and B(a)P, in the main stream(MS)and side stream(SS)of smoke held by various kinds of smoking set were determined. Results showed that the toxicant resistance by bamboo water-filtered smoking set for TPM, Nicotine and B(a)P was 56.1%, 61.7% and 40.2% respectively. The resistance by bamboo water-filtered smoking set in greater than that by copper waterfiltered smoking pot and smoking pipe. The resistance efficiencies of some toxicants by tobacoo filter paper tips made by cellulose acetate fiber+charcoal+paper are: TPM 66.8%, Nic 56.3% and Tar 67.4%, cellulose acetate fiber+charcoal are TPM 53.6%, Nic 48.0% and Tar 54.1%, cellulose acetate fiber are: TPM 36.4%, Nic 34.2% and Tar 34.6%, and Polypropyrene fiber are: TPM 24.5%, Nic 33.9% and Tar 24.0%.
