Experimental Research on the Entrance Percentages of Harmful Elements into Gas and Solid during the Process of Smoking

LI Yi-lin1,Ni Shi-jun2,GUO Ya-jie1,XIE Bin3,SHI Ze-ming2(1.College of Material and Chemistry,Chengdu University of Technology,Chengdu 610059,China;2.College of Nuclear and Automation Engineering,Chengdu University of Technology,Chengdu 610059,China;3.College of Information and Magement,Chengdu University of Technology,Chengdu 610059,China)  
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 movement percentages being Pb44.53%,Be23.90%,Ni19.60%,and Cr19.56%.Different cigarettes show differences in the contents of those elements,but there is no difference in the behavior of element movement.Lead and Cd may be the elements which are most released from cigarette to air.
