    Stalk position effect on harmful and potentially harmful cigarette smoke constituents in Burley tobacco: a case study

    VERRIER J-L.(1); DESTRUHAUT S.(2); COLARD S.(3)
    (1) Imperial Tobacco Group, Institut du Tabac, Bergerac, France; (2) Imperial Tobacco Group, SEITA, Fleury-les-Aubrais, France; (3) Imperial Tobacco Ltd, Bristol, U.K.
    Cured leaf chemistry varies sharply according to stalk positions and variations of smoke yields of harmful and potentially harmful constituents (HPHCs) are also expected. To quantitatively assess the effects on HPHC yields, Burley leaves of the...

    The chemical components identified in tobacco and tobacco smoke prior to 1954: a chronology of classical chemistry

    RODGMAN A.; PERFETTI T.A.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    Because of the excellent fractionation and identification technologies developed during the early-1950s, the compositions of tobacco and tobacco smoke, both classified as highly complex mixtures, have been defined more completely than the composition...

    The composition of cigarette smoke. An historical perspective of several polycyclic aromatic hydrocarbons

    RODGMAN A.; COOK L.C.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    Because of the significant advancements in fractionation, analytical, and characterization technologies since the early 1960s, hundreds of components of complex mixtures have been accurately characterized without the necessity of actually isolating...

    The composition of cigarette smoke: a catalogue of the polycyclic aromatic hydrocarbons

    RODGMAN A.; PERFETTI T.A.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    Classified as toxicants in many of the substances to which humans are exposed are the polycyclic aromatic hydrocarbons (PAHs). Such exposures include air pollutants from a variety of sources, foodstuffs and beverages, and tobacco smoke. Since the...

    Some studies of the effects of additives on cigarette mainstream smoke properties. III. Ingredientsreportedly used in various commercial cigarette products in the USA and elsewhere

    RODGMAN A.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    In the mid-1980s, each major US cigarette manufacturer prepared a list of those ingredients added at that time to its cigarette products. The lists were combined into one and submitted to the US Office of Smoking and Health in 1986. It comprised 599...

    Some studies of the effects of additives on cigarette mainstream smoke properties. II. Casing materials and humectants

    RODGMAN A.
    Alan RODGMAN, 2828 Birchwood Drive, Winston-Salem, North Carolina, 27103-3410, USA
    Examination of extensive laboratory data collected during the past four decades, particularly those unpublished data generated in the 1950s and 1960s, indicates that none of the materials used as casing materials (sugars, licorice, cocoa) and...
