Abstract

Tobacco mainstream smoke (MSS) and sidestream smoke (SSS), butts, and ashes from commercial cigarettes and maleic hydrazide (MH) spiked cigarettes were analyzed for their MH contents. The MH transfer rates obtained for MSS ranged from 1.4% to 3.7%, for SSS ranged from 0.2% to 0.9%, and for butts ranged from 1.1% to 1.9%. And as expected, MH is absent in ashes. The transfer rate of MH into mainstream smoke is the top one during in transfer rate into main-stream, side-stream, ashes, and butts, and higher MH levels lead to more MH in smoke. Further, analysis of total MH in butts and ashes along with that in MSS and SSS indicates that much MH is destructed during the smoking process.

摘要

对商业香烟以及添加了马来酰肼（MH）的香烟产生的烟草主流烟雾（MSS）、侧流烟雾（SSS）、烟头和烟灰中的MH含量进行了分析。MSS的MH转移率在1.4%至3.7%之间，SSS的MH转移率在0.2%至0.9%之间，烟头的MH转移率在1.1%至1.9%之间。正如预期的那样，烟灰中不含MH。在进入主流烟雾、侧流烟雾、烟灰和烟头的转移率中，MH向主流烟雾中的转移率是最高的，并且更高的MH水平会导致烟雾中含有更多的MH。此外，对烟头和烟灰以及MSS和SSS中的总MH进行分析表明，在吸烟过程中有大量的MH被破坏。
