    Stalk position effect on harmful and potentially harmful cigarette smoke constituents in Burley tobacco: a case study

    VERRIER J-L.(1); DESTRUHAUT S.(2); COLARD S.(3)
    (1) Imperial Tobacco Group, Institut du Tabac, Bergerac, France; (2) Imperial Tobacco Group, SEITA, Fleury-les-Aubrais, France; (3) Imperial Tobacco Ltd, Bristol, U.K.
    Cured leaf chemistry varies sharply according to stalk positions and variations of smoke yields of harmful and potentially harmful constituents (HPHCs) are also expected. To quantitatively assess the effects on HPHC yields, Burley leaves of the...

    Investigations on cigar burning and yields under different smoking intensities

    MUELLER C.(1); COLARD S.(2)
    (1) Imperial Tobacco Group, Reemtsma Cigarettenfabriken GmbH, Hamburg, Germany; (2) Imperial Tobacco Ltd, Bristol, U.K.
    In order to better understand the effect of smoking parameters on the cigar burning process and mainstream smoke yields, a pilot study was conducted. A ‘large’ commercial cigar (weight about 6.5 g) was investigated for the generation of ‘tar’,...

    Leak-based method for measurement of low air permeability of cigarette papers

    COLARD S.(1); CHOLET G.(2); TESTUD M.(2)
    (1) Imperial Tobacco Ltd, Bristol, U.K.; (2) Sodim SAS, Fleury-les-Aubrais, France
    The air permeability of cigarette paper is assessed currently under the ISO 2965 standard by applying a constant difference of pressure of 1 kPa between the two faces of a paper and by measuring the corresponding airflow. Lower Ignition Propensity...

    Product comparison: the risk associated with multiple testing

    VERRON T.(1); CAHOURS X.(1); COLARD S.(2)
    (1) Imperial Tobacco Group, SEITA, Fleury-les-Aubrais, France; (2) Imperial Tobacco Ltd, Bristol, U.K.
    Manufacturers are increasingly being asked by regulatory authorities to report data on their new products. For example, the United States Food and Drug Administration (FDA) requires that these data are used to compare a new tobacco product to a...

    Modelling of the effect of indoor intermittent emissions produced by electronic cigarette users on exposure of bystanders

    COLARD S.(1); VERRON T.(2)
    (1) Imperial Tobacco Ltd, Bristol, U.K.; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    In the context of the regulatory debates about the appropriateness to ban or not e-vapour use in public places, the need to understand and identify the factors affecting bystanders’ exposure is particularly useful. The propagation, dilution and...

    Smoke analysis of fine-cut tobacco – a predicting model and other challenges

    TEILLET B.(1); VERRON T.(1); CAHOURS X.(1); COLARD S.(2)
    (1) Imperial Tobacco Group, SEITA, Fleury-les-Aubrais, France; (2) Imperial Tobacco Ltd, Bristol, U.K.
    The ISO 15592-1 to 3 standards specify methods for the sampling, conditioning and determination of nicotine and “tar” in the mainstream smoke generated by the combustion of fine-cut tobacco. As originally requested by several European government...
