Pr. Nelson et al., STUDIES OF ENVIRONMENTAL TOBACCO-SMOKE GENERATED BY DIFFERENT CIGARETTES, Journal of the Air & Waste Management Association, 48(4), 1998, pp. 336-344
A method was developed to reproducibly measure environmental tobacco s
moke (ETS) components generated by different cigarettes. Measurements
were carried out in an unventilated, controlled environment chamber. T
rue ETS (the aged and diluted combination of exhaled mainstream plus s
idestream smoke) was generated by human smokers. To reliably quantitat
e components normally present at trace levels, the comparisons were ca
rried out at elevated ETS concentrations-greater than 40 times those t
ypically encountered in ''real-world'' settings. The method was applie
d to four commercially available cigarettes and a cigarette prototype
that primarily heats tobacco. Forty-three properties and components of
the gas and particulate phases of ETS generated by the different ciga
rettes were measured. Good precision of measurement was obtained both
within and between tests. Statistically significant differences in the
concentration of ETS components were observed among the different com
mercial cigarettes and between the commercial and prototype cigarettes
. Most ETS components from the prototype cigarette were reduced by >90
% when compared to the commercial cigarettes. The method was used to d
etermine the effect of cigarette design changes on the generation of E
TS.
