    Reduction of tobacco specific nitrosamines in air-cured tobacco

    LI Qinglin; KRAUSS M.; COLASSACO D.; BOKELMAN G.; GADANI F.; ROSSI L.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Antioxidants, such as phenolics, tocopherols and carotenoids in tobacco leaves, are known to interfere with oxidation processes through chain-breaking reactions or through scavenging of free radicals. The induction or up-regulation of these and other ...

    Application of nanoparticle iron oxide in cigarette for simultaneous CO and NO removal in the mainstream smoke

    PING L.; RASOULI F.; HAJALIGOL M.R.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Based on the unique temperature and oxygen profiles in a burning cigarette, a novel approach is proposed in this paper to use a single oxidant/catalyst in the cigarette filler for simultaneous removal of carbon monoxide (CO) and nitric oxide (NO) in ...

    Set up of a new analytical methodology for the determination of polycyclic aromatic hydrocarbons in particulate phase mainstream cigarette smoke

    LIONETTI G.; CIARAVOLO S.; GIONTI M.; NUNZIATA A.; PIERRI E.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    A method for the rapid and selective extraction of polycyclic aromatic hydrocarbons (PAHs) from particulate phase mainstream cigarette smoke was developed using microwave assisted extraction. This system allows the simultaneous extraction of many samples ...
