    Thermal decomposition of pesticides in the presence of oxygen. Part B: benzimidazolyl carbamates

    SENNECA O.; SCAMARDELLA A.M.; CIARAVOLO S.; LIONETTI G.; NUNZIATA A.
    Institute of Research on Combustion, National Research Council, Naples, Italy.
    The paper addresses thermal decomposition under oxidative conditions of two largely used fungicides, belonging to the family of benzimidazolylcarbamates, namely Benomyl (methyl 1-(butylcarbamoyl)benzimidazol-2-ylcarbamate) and Carbendazim (methyl ...

    Thermal decomposition of pesticides in the presence of oxygen. Part C: pyrethroids

    SENNECA O.; SCHERILLO F.; CIARAVOLO S.; LIONETTI G.; NUNZIATA A.
    Institute of Research on Combustion, National Research Council, Naples, Italy.
    The work is part of a series of papers on thermal degradation under oxidative conditions of different types of pesticides (1-3). In the present paper a set of six synthetic pyrethroids has been investigated as regards their degradation pattern and their ...

    Biomonitoring of nicotine and cotinine in saliva to assess human smoke exposure: a new validated analytical methodology

    PIERRI E.; CIARAVOLO S.; GIONTI M.; LIONETTI G.; NUNZIATA A.
    British American Tobacco Italia, R&D, Naples, Italy
    Nicotine, the most important tobacco alkaloid, is quickly metabolized in humans. Cotinine is the main metabolite of nicotine and it is obtained by oxidation of the pyrrolidine ring. The presence of nicotine, cotinine and other metabolites in biological ...

    Determination of NNAL in smokers' urine by LC-MS/MS: a comparison of sample preparation procedures

    MOLA M.; CIARAVOLO S.; LIONETTI G.; NUNZIATA A.
    British American Tobacco Italia, R&D, Naples, Italy
    4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a potent pulmonary carcinogen in rodents and may play a significant role as a cause of lung cancer in smokers. NNK uptake can be quantified by the analysis of two of its metabolites in urine, NNAL ...

    Volatile nitrosamines in cigarette smoke: a new sampling and analytical method

    MODESTIA F.; CIARAVOLO S.; LIONETTI G.; NAPPI L.; NUNZIATA A.
    British American Tobacco Italia, R&D, Naples, Italy
    Volatile nitrosamines (VNAs) in cigarette smoke are formed from decarboxylation of N-nitrosoaminoacids or pyrolitic nitrosation of secondary amines. Previous studies show that the levels of VNAs are much higher in sidestream smoke than mainstream smoke. ...

    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 ...
