Description:
Environmental tobacco smoke (ETS) has been analyzed with respect to several components following smoking of research cigarettes in an experimental chamber. arameters analyzed and their airborne yield per cigarette included: particulate matter (10 mg) and its mutagenic activity in a Salmonella bioassay, carbon monoxide (67 mg), nitrogen oxides (2 mg), nicotine (o.83.3 mg), formaldehyde (2 mg), acetaldehyde (2.4 mg), acrolein (0.56 mg), benzene (0.5 mg) and several unsaturated aliphatic hydrocarbons (e.g. 1,3-butadiene) of which isoprene (3.1 mg) had the highest yield. TS from commercial cigarettes were likewise analyzed in the experimental chamber and at a public location. he relative component composition is similar for the research and commercial cigarettes. ll components analyzed were present at concentrations above the background concentrations. soprene might be utilized as a tobacco smoke tracer for unsaturated aliphatic hydrocarbons.
