Influence of cigarette smoking parameters on burning temperature and delivery levels of smoke constituents

RM1 smoking machine was used to smoke cigarette under different variables including puff flow rate profiles, puff volume, puff duration, and puff frequency. Infrared camera AGEMA SC3000, superior to most infrared systems used in previous experiments, was used to observe peripheral solid-phase temperature. GC method was used to analyze H2O, nicotine, CO, and ploycyclic aromatic hydrocarbons (PAHs) in cigarette smoke. Results show that 1) Higher air flow rate can result in higher burning temperature; 2) Lower puff volume induced lower temperature and lower deliveries of nicotine, tar, CO, PAHs per cigarette smoke; 3) Shorter puff duration induced higher temperature, with slight effects on smoke deliveries; 4) Higher temperature occurred with lower puff frequency and induced higher nicotine, tar and CO deliveries per puff smoke; 5)Yield of PAHs per puff smoke can also be significantly affected by temperature.
