摘要
利用全自动人模拟吸烟机采集香烟主流烟气凝相物，对其主要诱变物进行分析比较、结果表明：复合滤嘴能有效减少主流烟气Ｂａｐ、焦油、ＴＰＭ、烟碱、２１０Ｐ。、Ｃｄ和Ｐｂ诱变物，滤除率分别为８３．９～９３．５％、４３．３～５４．４％、４３．３～５３．７％、１７．０～５７．５％、５６．１～６９．３％、７２．９～９８．２％、５３．２～７５．５％。对ＢａＰ、Ｃｄ、Ｐｂ和２１０Ｐ。滤除率明显高于醋酸纤维滤嘴，对于减少诱变物在肺内沉积具有积极的意义和较大的应用价值。本文提出ＢａＰ、２１０Ｐ。应作为香烟质量和滤嘴滤效评价指标。
Tip The mutagens in the cigarette mainstream smoke collected by auTosmoking machine were determined. The results showed that BaP. tar, TPM, nicotine. 210 Po, Cd, and Pb were decreased in the maintream smoke filtrated by the filter tip.The decrease rate is 83. 9～93. 5%, 43. 3～54. 4%, 43. 3～53.7%, 17. 0～57. 5%. 56. 1～69. 3%. 72. 9～98. 25%, 53. 2～75.5% respectively. The fitrability in BaP,Cd,Pb and 210PO was respectively higher than that of acetate fibre filter group singnificantly. There was more active significance and use valne on decreasing of exposure to the mutagens (BaP,Ph, 210 po,ect. )This paper alse suggested that BaP. 210 Po should be used for the evaluation index on the cigarette quality and the filtrating efficiency of the tip.
