Selenium in mainstream and sidestream smoke of cigarettes containing fly ash-grown tobacco.
The quantities of selenium, tar and nicotine present in mainstream (MS) and sidestream (SS) smoke of machine-smoked cigarettes was studied. The cigarettes were prepared from tobacco purposely cultured on fly ash-amended soil so as to increase its selenium concentration. Selenium concentration was found to be the same in the gaseous phase of both MS and SS smoke, but its concentration was significantly higher (p less than 0.05) in the particulate matter of the MS smoke. Tar was higher in MS smoke and nicotine in SS smoke. Factors affecting selenium concentrations in tobacco and its possible environmental significance are discussed.
