    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...

    Reduced levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol in smokers of cigarettes produced from nitrosamine-free tobacco

    DJORDJEVIC M.; BARR W.H.; BRANCIFORTE S.; BURTON H.R.; JAFFE J.H.
    American Health Foundation, New York, USA
    Model studies on lung cancer in animals have shown that adenoma and adenocarcinoma are specifically elicited by nicotine-derived tobacco-specific N-nitrosamines (TSNA), such as 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Lowering or...

    Influence of aqua terra hydrogel on growth, development and yield of light cigarette tobacco

    KOSCIK B.; KOWALCZYK-JUSKO A.
    University of Agriculture, Lublin - Institute of Agricultural Sciences, Zamosc, Poland.
    The aim of introductory field and pot experiments which were carried out in Zamosc in the years of 1995-1997 was to study the influence of Aqua Terra hydrogel on the growth, development and yield of light cigarette tobacco. Hydrogels are substances...

    Smoking behavior and exposure to selected toxic agents among smokers of low- and medium-yield cigarettes

    DJORDJEVIC M.J.; HOFFMANN D.; THOMPSON S.; STELLMAN S.D.
    American Health Foundation, New York, USA
    Intake dosages of mainstream smoke components were determined in 52 smokers of low-nicotine (LN) cigarettes (42% male) and 55 smokers of medium-nicotine (MN) cigarettes (55% male) by measuring smoking profiles for each smoker using a...

    Distribution of smoking parameters and self-administered doses of select smoke components among different population groups

    DJORDJEVIC M.V.; HOFFMANN D.; THOMPSON S.; STELLMAN S.D.
    American Health Foundation, New York, USA
    Human smoking behavior is characterized by a wide spectrum of smoking patterns which result in significant variations in "tar" and nicotine exposure. In an ongoing, large population study we are measuring puff volume, duration, interval between puffs...

    A comparison of the smoke yields of selected components in the mainstream smoke of the leading U.S. and Japanese cigarettes

    DJORDJEVIC M.V.; EIXARCH L.; HOFFMANN D.
    American Health Foundation, New York, USA
    Japanese men prefer to smoke cigarettes with charcoal filter tips which are known to selectively reduce certain volatile agents in mainstream smoke (MS). During the past two decades, at least 68% of all cigarettes sold in Japan had charcoal filter...

    The chemical composition of mainstream cigarette smoke generated under FTC/CORESTA and actual human smoking (AHS) conditions

    DJORDJEVIC M.V.; FAN J.; FERGUSON S.; HOFFMANN D.
    American Health Foundation, New York, USA
    Actual human smoking parameters can differ significantly from those used in the FTC/CORESTA machine-smoking standard methods. To analyze and compare the smoke yields obtained by standardized machine-smoking and by using AHS conditions, the smoking...
