    Tobacco-specific N-nitrosamines (TSNA) in tobacco and mainstream smoke of the leading Polish cigarettes: a comparison with the U.S. and Japanese brands

    DJORDJEVIC M.V.; PROKOPCZYK B.; ZATONSKI W.
    American Health Foundation, New York, USA
    The evidence that tobacco-specific N -nitrosamines (TSNA) play an important role in cancer induction by tobacco products is strong. The nicotine-derived 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and polycyclic aromatic hydrocarbons are...

    A possible way to reduce toxic compounds content (e.g.: nitrosamines) produced during the dark-fired tobacco (var. Kentucky) fermentation: preliminary data on the tobacco leaves fermentation process

    AURELI G.; GHELARDINI P.; MATARAZZO G.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    The aim of this study is to improve the industrial fermentation of dark-fired cigar filler leaf tobacco (var. Kentucky), employed in the production of "toscano' cigars, and the possible reduction of some toxic substances content (e.g. nitrosamines)...

    Relationship between tobacco-specific nitrosamines (TSNA) and microbial populations from Ontario-grown tobacco flue-cured under direct and indirect heating

    MORIN A.; DUMONT J.; RATAVICIUS A.; PORTER A.; DUNN P.
    Imperial Tobacco Canada Ltd, Montreal, Quebec, Canada
    Ontario-grown tobacco was flue-cured under two different regimes: direct and indirect heating. Tobacco was sampled every 24 h during curing. TSNA were extracted from ground tobacco leaves using supercritical carbon dioxide and then analyzed by...

    The evaluation and prediction of the ETS particles deposition on walls by experiment and numerical simulation

    ASAI T.; NISHINA T.; SHIMADA M.; OKUYAMA K.
    Japan Tobacco Inc., Tobacco Science Research Lab., Yokohama, Kanagawa, Japan.
    It is important to analyze and predict ETS particle behavior in rooms for the evaluation of smoking environments and the development of control technologies. As control technologies for ETS, we have developed ventilation and smoke separating...

    Measurements of particle numbers and diameters of sidestream cigarette smoke by laser-photodetection in an experimental room

    INTORP M.; JENNING W.R.; KANNENGIEßER D.
    H.F. & Ph.F. Reemtsma GmbH, Research & Development, Hamburg, Germany.
    The contribution of respirable suspended particles (RSP) from sidestream cigarette smoke (SS) to indoor air quality had been and is still an important factor to evaluate the contamination caused by smouldering cigarettes. To evaluate the contribution...
