卷烟抽吸过程中重金属元素的转移量及转移率研究

Study on the deliver amount and deliver rate of heavy meta1 elements during smoking

为了解卷烟抽吸过程中重金属元素的转移量和转移率,采用外加法于卷烟样品中添加不同含量的重金属元素标样,抽吸后对样品主流烟气总粒相物、主流烟气气相、灰份和滤嘴中的重金属元素进行分析检测,并进一步研究了重金属元素在不同添加量时向主流烟气总粒相物、主流烟气气相、灰份和滤嘴中的转移量及转移率.结果表明,主流烟气气相中未检测到重金属元素的存在;重金属元素在烟支燃吸过程中大部分均转移至灰份中,只有少量转移至主流烟气总粒相物和滤嘴中;此外,重金属元素向主流烟气总粒相物和滤嘴中的转移具有一定的饱和度.

In order to study the deliver amount and deliver rate of heavy meta1 elements during smoking,heavy metal elements of different amounts were added to the same cigarette sample,and heavy metal elements in TPM,gas phase of main stream smoke,ash and filter rod were determined after smoking.Then the deliver amount and deliver rate of heavy metal elements in TPM,gas phase of main stream smoke,ash and filter rod at differentadding amounts were studied.The results showed that heavy metal elements were not detected in gas phase of main stream smoke.heavy metal elements were mostly transferred into ash,while just a little amount of them were transferred into TPM and filter rod during smoking.
