| 摘 要： | 在香烟燃烧过程中会有部分元素残留在灰相,另一部分元素随气相迁移进入大气和吸烟者呼吸道,本文借助稳定残留在烟灰中的元素K为桥梁,估算了三种品牌香烟中8个有害元素在香烟燃烧过程中随气相迁移和残留在灰相中的分配比例。Hg、Cd、As、Se是其中容易进入气相的元素,迁移比例为Hg89.40%、Cd73.92%、As67.12%、Se61.68%,Pb、Be、Ni、Cr则容易残留在烟灰中,迁移比例为Pb44.53%、Be23.90%、Ni19.60%、Cr19.56%。不同品牌的香烟中元素含量和元素的迁移状况虽有不同,但元素总体表现一致。考虑元素在香烟中的赋存量和迁移进入气相的比例后,Pb、Cd是燃烧过程中释放量较大的元素。 |

| Abstract: | Some elements exist in solid ash,while some find their way into gas and human body in the process of cigarette burning.Potassium is taken as a bridge,which exists totally in ash during cigarette burning.The entrance percentages of 8 harmful elements into gas and solid were estimated in smoking process.The results showed that Hg,Cd,As and Se are elements which like to move into gas,with the movement percentages being Hg89.40%,Cd73.92%,As67.12%,Se61.68%;Pb,Be,Ni.and Cr seem to stay in the solid,with the movem... |
