Abstract:
In order to study the influences of air permeabilities of tipping paper and plug wrapper on the migration of elements(Cr,Ni,As,Se,Cd and Pb) in cigarette during burning,cigarettes with tipping paper and plug wrapper of different air permeabilities were prepared according to single factor design,and the contents and migration ratios of the said elements in tobacco rod,filter,butt,mainstream cigarette smoke,sidestream cigarette smoke and ash were determined by inductively coupled plasma mass spectrometry.The results showed that:1) Except for Cd,the migration ratios of Cr,Ni,As,Se and Pb into cigarette ash were above 70% during cigarette burning,while their migration ratios into mainstream and sidestream smoke were very low(<10%).2) With the increase of air permeabilities of tipping paper and plug wrapper,the migration ratios of the said six elements into mainstream smoke and butt decreased to a certain extent,however those into cigarette ash increased.3) Air permeabilities of tipping paper and plug wrapper showed little effects on the migration ratios into sidestream smoke.
