<abstract><title style='display:none'>Abstract</title> The purpose of this study was to learn how cellulose pyrolysis was affected by changes in atmospheres, by varied pyrolysis temperatures, by the addition of inorganic materials, and by chemical modifications of the cellulose molecule. These studies have led to the hypothesis that cellulose can pyrolyse by two different modes to form B(a)P. Large quantities of B(a)P can be formed by high temperature (850°C) isothermal pyrolysis of cellulose via a very efficient gaseous reaction route. In this reaction the B(a)P yield decreased in the presence of iron, cobalt, and nickel while the yield increased with increasing temperatures and with the introduction of oxygen into the system. In contrast, graduated heating experiments demonstrated that B(a)P began to form at 450°C. This reaction was inefficient with respect to B(a)P yield and was unaffected by the presence of metals. The B(a)P precursors were hypothesized to be nonvolatile, being formed via a solid state decomposition of cellulose and involving the generation of free radicals. This reaction was inhibited by the presence of nitric oxide or salts generating nitric oxide. Additionally, oxidation of the cellulose molecule at the C6 position produced a decreased B(a)P yield.</abstract>

Contributions to Tobacco and Nicotine Research (formerly: Beiträge zur Tabakforschung International / Contribution to Tobacco Research International) publishes articles with a focus on tobacco, nicotine, and related consumer products. In addition, all aspects of research on the tobacco plant as well as on product technology and manufacturing are relevant for the Journal. Products of interest comprise (i) combustible tobacco products (cigarettes, cigars, pipes, etc.), (ii) smokeless tobacco (SLT) products (snuff, snus, chewing tobacco, etc.), (iii) tobacco heating products (THP), (iv) electronic cigarettes (e-cigs, w/o nicotine), (v) oral nicotine delivery (OND) products. All scientific investigations on product-related properties (including physical, chemical, biological, and toxicological properties) as well as on the influence on consumers’ behavior and response (including acute and long-term product use patterns and biomarker profiles) are considered for publication. Submissions can be of the following types: original investigations, reviews, short reports commentaries, letters to the editor.
