重金属元素在卷烟主流烟气中迁移率分析

本课题采用电感耦合等离子体质谱法测定卷烟及卷烟主流烟气中重金属元素铬（Cr）、镍（Ni）、砷（As）、硒（Se）、镉（Cd）和铅（Pb）含量,计算重金属元素在主流烟气中的迁移率,结果表明,卷烟重金属元素主要来源于卷烟烟丝,基本未迁移到卷烟主流烟气气相中,仅有一部分迁移到卷烟主流烟气粒相中,且迁移率均在10％以下.

On the Mobility of Heavy Metals in the Mainstream Cigarette Smoke

By using inductively coupled plasma mass spectrometry, this study measured the contents of heavy metals inclu- cling Chromium （Cr） , Nickel （Ni）, Arsenic （As） , Selenium （Se） , Cadmium （Cd） and Lead （Pb） in the cigarettes and cigarette mainstream smoke and calculated their mobility in the mainstream smoke. The results showed that heavy metals mainly came from cigarette tobacco. They basically did not migrate to the vapor phase of cigarette mainstream smoke, only a part of them, less than 10%, migrated to mainstream cigarette smoke particle phase.
