Elements enter in a body in the course of smoking.Based on the fact that K stays in ash when one smokes,taking K as an reference,this paper aims to study the elements transfer of one brand cigarette during the smoking by a new way,that is,the element ratio method.Cu,Fe,Zn and Hg,Cd,As,Pb,Cr,Ni are surveyed by sampling cigarette sticks and ash of real smoking to evaluate the dose of these 9 elements entering in air during smoking.The transfer of Cu is most,reaching 83.3% of 50.5μg/g in this cigar.That of Pb,As and Cd is the second,reaching 62.1% of 3.50 μg/g,95.4% of 0.536 μg/g,57.3% of 0.500 μg/g.So,Pb,As and Cd should be the most elements that enter into the air during smoking and the aim elements of cigarette prescription adjusting.The result shows that the element ratio method is an effective and fast new way to evaluate the element transfer during smoking.
