Effects of Topography-Related Puff Parameters on Carbonyl Delivery in Mainstream Cigarette Smoke.

ABSTRACT: Smoking topography parameters differ substantially between individual smokers and may lead to significant variation in tobacco smoke exposure and risk for tobacco-caused diseases. However, to date, little is known regarding the impact of individual puff parameters on the delivery of many harmful smoke constituents including carbonyls. To examine this, we determined the effect of altering individual puff parameters on mainstream smoke carbonyl levels in machine-smoked reference cigarettes. Carbonyls including formaldehyde, acetaldehyde, crotonaldehyde, propionaldehyde, methyl ethyl ketone (MEK), acrolein, and acetone were determined in cigarette smoke by HPLC after derivatization with 2,4-dinitrophenylhydrazine (DNPH). Deliveries of all carbonyls were nearly two-fold greater when cigarettes
