本实验模拟人的吸烟状况,测定香烟烟气对草履虫(Paramecium aurelia)的急性致死、急性生理伤害和抑制细胞繁殖率,并比较了带过滤嘴与不带过滤嘴香烟的毒性作用。结果表明同一牌号的香烟,带过滤嘴的较不带过滤嘴的毒性明显降低。 In this study, the smoking status of human beings was simulated. The acute lethality, acute physiological injury and cell multiplication rate of cigarette smoke on Paramecium aurelia were measured. The toxic effects of cigarette filter with and without filter were compared. The results showed that cigarettes of the same brand, with less filter with a filter significantly reduced the toxicity.
