    Sampling and analysis consideration for determination of hexavalent chromium in mainstream and sidestream tobacco smoke

    LIONETTI G.; CIARAVOLO S.; MODESTIA F.; NUNZIATA A.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    Chromium is present in the environment mainly in the oxidation states (III) and (VI). Airborne hexavalent chromium is a known human respiratory carcinogen and allergen. A method for determining hexavalent chromium in mainstream and sidestream tobacco ...

    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 ...

    Microwave assisted extraction and thermal energy analysis of tobacco specific nitrosamines in tobacco and tobacco products

    MOLA M.; CIARAVOLO S.; LIONETTI G.; NUNZIATA A.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    This work reports the use of microwave energy for the extraction of tobacco specific nitrosamines (TSNAs) from tobacco and their detection with a thermal energy analyser (TEA). Conventional sample preparation procedures for the TSNAs involve extraction ...

    Determination of tobacco specific nitrosamines in tobacco and tobacco products by gas chromatography-thermal energy analysis

    MOLA M.; LIONETTI G.; NUNZIATA A.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    Nitrosamines are chemical compounds that have been linked to some types of cancer. They are not present in freshly harvested green tobacco but they are primarily formed during drying, curing, aging and especially fermentation, by nitrosation of tobacco ...

    Tobacco specific nitrosamines in mainstream smoke: development of a gas chromatographic method for their determination

    MOLA M.; LIONETTI G.; NUNZIATA A.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    Nitrosamines are chemical compounds that are present in tobacco and tobacco smoke. When tobacco burns during smoking, the tobacco specific nitrosamines can transfer to smoke as well as decompose thermally, and additional amounts of the nitrosamines can be ...

    A potentiometric - coulometric method for the determination of cyanide in mainstream cigarette smoke

    LIONETTI G.; FERRI D.; MANFREDI C.; MODESTIA F.; NUNZIATA A.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    Hydrogen cyanide is considered to be one of the most toxic agents present in the vapor phase of cigarette smoke. The aim of this method is to determine the amount of hydrogen cyanide and its derivates. It consists of the measurement of a second type ...

    Selective extraction method of polycyclic aromatic compounds from tobacco smoke condensate and quantitative determination by HPLC - UV and fluorescence detection

    MAURIZI S.; ROSSI S.; LIONETTI G.; NUNZIATA A.
    ETI S.p.A., Research, Chemistry Dept., Rome, Italy.
    The presence of PAHs in both mainstream and sidestream tobacco smoke has been well established by GC/MS analysis even if official methods for their quantitative determination do not exist. The aim of this research was to set up a selective extraction ...
