    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...

    (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...

    (1) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France; (2) Imperial Tobacco Limited, Bristol, UK
    In the context of methodology for cigarette product characterisation, it is important to subject the method to its intended-use (e.g. regulatory requirement) in order to confirm its “fitness for purpose” as described in ISO17025. The objective is to...
