Effects of Smoking Regime on Ammonia Delivery in Mainstream Cigarette Smoke

In order to investigate the influences of smoking regime on the ammonia delivery in mainstream cigarette smoke,4 cigarette samples were smoked under different smoking regimes on smoking machine,and the ammonia deliveries in mainstream smoke of these samples were determined by ion chromatography. The results showed that the ammonia deliveries in mainstream smoke varied greatly with the changes of smoking regime. The ammonia delivery in mainstream smoke and the ammonia intake by smoker could be reduced by decreasing puff volume,prolonging puff duration and interval,increasing filter ventilation and butt length.
