Smoke analysis

In order to ascertain that the NDELA formation does not occur as a result of trapping of the smoke or during the analysis, we added diethanolamine to tobacco prior to extraction with ethyl acetate in the presence of ascorbic acid. The control value for NDELA was 121 ppb and the experiment with 5.5 iqg diethanolamine addition yielded 113 ppb NDELA. For control of the smoke analysis we added 5.5 mg of DELA in the solvent trap and smoked cigarettes known to be free of DELA. Analysis of the trapped material showed no significant quantities of NDELA, so that artifactual formation of this nitrosamine during smoke collection and analysis can be ruled out. 

The smoke analysis of cigarettes made from the same tobacco blend, but with and without filter tips revealed that cellulose acetate retains TSNA selectively (Table VIIl). This phenomenon is clearly established for a large number of filter cigarettes. 

Of special interest in smoke analysis (both mainstream and sidestream) are a number of compounds that, although present in low levels in cigarette smoke, are considered [58-61] to have adverse effect on human health. A list of the more common such compounds analyzed in cigarette smoke and their likely sources is given in Table 16.2.8. The table also indicates the range of these compounds in the mainstream of a reference cigarette (1R4F). 

Instrumental neutron activation analysis (INAA) is an extremely sensitive method for the determination of metals and metal isotopes. INAA has been used successfully by Nadkarni et al. (20A73), Jenkins et al. (1934) and Kubota (2214) to determine numerous inorganic constituents (elements and several elemental isotopes) in both tobacco and tobacco smoke (1933). The use of INAA for tobacco and tobacco smoke analysis has been accepted worldwide (1933). Tobacco is ideally suited for INAA because of its large abundance and variety of inorganic components. Tobacco is a readily available, easy-to-handle solid, it produces little gas during irradiation, and is rapidly assayed by INAA. The literature on the use of INAA in tobacco is very large because tobacco is often used as a model in non-tobacco-oriented...
