In order to study the effects of filter ventilation rates on the aromatic component deliveries in mainstream cigarette smoke, the deliveries of routine chemical components and 32 aromatic components in gas phase and particulate phase of mainstream cigarette smoke of 6 cigarette samples with different filter ventilation rates (0, 10%, 25%, 40%, 54% and 64%) were determined. The results showed that: 1) the deliveries of routine chemical components decreased with the increase of filter ventilation rate; 2) the total delivery of the 30 aromatic components in mainstream cigarette smoke decreased with the increase of filter ventilation rate, for the components of the same group, the total delivery of those with lower boiling points was less than those with higher boiling points; 3) the distribution ratios of the 30 aromatic components in gas / particulate phase increased with the increase of filter ventilation rate, moreover, the increasing rate of the distribution ratios of the same group of aromatic components increased with the increase of their boiling points; 4) the total deliveries of the 30 aromatic components per unit nicotine yield in gas and particulate phases negatively correlated with the filter ventilation rate of cigarette.
