    What fundamental tobacco science teaches us about heated tobacco products – assessment on THP1.0

    EATON D.; JAKAJ B.; FORSTER M.; LIU Chuan; PRASAD K.
    British American Tobacco (Investments) Limited, R&D, Southampton, U.K.
    Heated tobacco products are designed to reduce toxicant emissions in aerosol as compared to cigarette smoke. Different heating mechanisms have been used in this type of product, either using solid fuels (e.g. charcoal) or electrical energy (e.g....

    Synchrotron X-ray analysis of the oxidation states of arsenic and cadmium in cut tobacco, cigarette ash and mainstream smoke

    HU Jin; LIU Chuan; McADAM K.G.
    British American Tobacco, Group R&D, Southampton, UK
    Mainstream smoke from cigarettes is known to contain various toxic metals, including As, Cd, Cr, Pb, Ni and Se. It is of interest to study the potential contribution of these metals to the overall toxicity of smoke. The oxidation state and chemical...
