摘 要:为研究ISO和加拿大深度抽吸(HCI)模式下滤棒吸阻和滤嘴长度对卷烟烟气中6种元素迁移率的影响,采用单因素设计方案制备了试验卷烟,考察了两种抽吸模式下滤棒吸阻和滤嘴长度参数引起的主流烟气和侧流烟气中铬(Cr)、镍(Ni)、砷(As)、硒(Se)、镉(Cd)和铅(Pb)迁移率的变化。结果表明:1在ISO模式下,滤棒吸阻与主流烟气中Ni,Pb,Cr和Cd 4种元素的迁移率及侧流烟气中Ni迁移率显著负相关,与侧流烟气中Cd迁移率显著正相关。滤嘴长度与主流烟气中6种目标元素的迁移率均显著负相关,与侧流烟气中Ni和Pb迁移率显著正相关。2在HCI模式下,滤棒吸阻与主流烟气中Pb迁移率显著负相关。滤嘴长度与主流烟气中6种目标元素迁移率和侧流烟气中Cr和Cd迁移率显著负相关,与侧流烟气中Pb迁移率显著正相关。In order to study the influences of filter rod draw resistance and filter length on the migration ratios of six elements (Cr, Ni, As, Se, Cd and Pb) into cigarette smoke under ISO and HCI smoking regimes, cigarette samples were prepared according to single factor design to that aim. The results showed that: 1) Under ISO smoking regime, filter rod draw resistance significantly negatively correlated to the migration ratios of Ni, Pb, Cr and Cd into mainstream cigarette smoke and Ni into sidestream cigarette smoke, while significantly positively correlated to the migration ratio of Cd into sidestream cigarette smoke. Filter length significantly negatively correlated to the migration ratios of the six elements into mainstream cigarette smoke, while significantly positively correlated to the migration ratios of Ni and Pb into sidestream cigarette smoke. 2) Under HCI smoking regime, filter rod draw resistance significantly negatively correlated to the migration ratio of Pb into mainstream cigarette smoke. Filter length significantly negatively correlated to the migration ratios of the six elements into mainstream cigarette smoke and Cr and Cd into sidestream cigarette smoke, while significantly positively correlated to the migration ratio of Pb into sidestream cigarette smoke.
