Distribution of Various Tobacco Smoke Components among Mainstream and Sidestream Smoke (A Survey) / Verteilung verschiedener Tabakrauchbestandteile auf Haupt- und Nebenstromrauch (Eine Übersicht)

On the basis of the literature, which is at present still readily surveyable, the results of the research done so far into the occurrence of various components of tobacco smoke in the sidestream smoke have been summarized. The amount of the smoke constituents occurring in the sidestream smoke is compared with that of the mainstream smoke: [XXX] The experimental arrangements used so far to record sidestream smoke are critically discussed. It transpires, for example, from the results of experimental research published so far that, in particular, the quantitative analysis results of sidestream smoke obtained by means of the Neurath chamber can be distorted by the temperature and atmospheric humidity obtaining in the chamber, with a trend towards higher figures, for example, of the nitrosamines. lt is therefore problematic to draw on the sidestream smoke results obtained by means of the Neurath sidestream smoke chamber to estimate the strain on the air of indoor rooms by the sidestream smoke of cigarettes.
