    SLONE S.; CANETE S.; SHELTON B.; JI H.; JACK A.M.; BUSH L.; CHAMBERS O.
    Center for Tobacco Reference Products, University of Kentucky, Lexington, KY, U.S.A.
    The constituents of raw tobacco products are naturally variable, and product design, the manufacturing process and the evolving science of tobacco analytics may increase this variability. The call for certified tobacco reference materials and their ...

    (1) University of Kentucky, Department of Plant and Soils, Lexington, KY, U.S.A.; (2) University of Kentucky, Kentucky Tobacco Research and Development Center, KTRDC Building, Lexington, KY, U.S.A.
    Even low concentrations of nitrogenous gases (NOx) produced during combustion in direct-fired flue-cured barns increase tobacco-specific nitrosamines (TSNAs) in the cured leaf. Previous work in France and Kentucky, and in our recent storage study, has ...
