Abstract: In order to investigate the effects of cigarette paper properties on the migration ratios of heavy metal elements in mainstream and sidestream cigarette smoke, 13 cigarette samples were prepared according to single factor design, the effects of permeability, grammage and combustion improver content of cigarette paper on the migration ratio of Cr, Ni, As, Se, Cd and Pb were studied. The results showed that: 1) The air permeability of cigarette paper significantly positively correlated to the migration ratio of Cd in sidestream cigarette smoke in the range of20-80 CU, while significantly negatively correlated to the migration ratios of As, Cd and Pb in mainstream cigarette smoke in the range of 20-50 CU. 2) The grammage of cigarette paper significantly positively correlated to the migration ratio of Cd in sidestream cigarette smoke, and had no obvious correlations with the migration ratios of the other elements. 3) The content of combustion improver in cigarette paper significantly negatively correlated to the migration ratios of Cr and As in mainstream cigarette smoke and that of As in sidestream cigarette smoke. In conclusion, cigarette paper properties have some, but not the same, effects on the migration ratios of Cr, Ni, As, Se, Cd and Pb in mainstream and sidestream cigarette smoke.
