Mainstream Cigarette Smoke

AbstractA method for the determination of menthol in a single puff of mainstream cigarette smoke is reported. A rotary smoking machine with a twin filter interface was used to smoke cigarettes with varying menthol and “tar” deliveries determined based on the Cambridge filter method. The twin filter interface mechanically switches to a new filter pad for collection of smoke from each cigarette puff. The individual filter pad extracts were analyzed by gas chromatography-mass spectrometry (GC-MS) to determine menthol puff-by-puff deliveries. Menthol puff-by-puff profiles show an increase in menthol smoke delivery with increasing puff count, a trend consistent with total particulate matter and smoke delivery profiles of other mainstream smoke constituents. The sum of single puff menthol deliveries is comparable to the whole cigarette menthol smoke delivery as collected on a single filter pad. This method can also determine quantitative puff-by-puff deliveries of other mainstream cigarette smoke constituents.

Mainstream Cigarette Smoke

AbstractA simple procedure for the collection of vapor phase (VP) of mainstream cigarette smoke for analysis has been developed. This procedure consists of collecting the VP on a commercial charcoal trap (ORBO™-32) followed by dissolution in acetone. The acetone extract can be analyzed by a gas chromatography/mass spectrometry (GC/MS) technique. A qualitative analysis of the collected VP has been performed for 3R4F Kentucky reference cigarette, allowing the identification of 138 compounds, some compounds being present in both VP and in particulate phase (PP) of cigarette smoke. A quantitative analysis method for acrylonitrile and α-methacrylonitrile (2-methyl-2-propenenitrile) was also developed, and the level of these compounds in 15 different cigarette brands was measured. Acrylonitrile quantitation was selected since this compound in smoke poses significant health related issues. α-Methacrylonitrile quantitation was selected due to the similar structure of this compound with acrylonitrile. The analyzed cigarettes were several Kentucky reference cigarettes including 1R5F, 2R4F, 3R4F, 2R1F, and 1R3F, several King Size (KS) commercial cigarettes from the US market including Basic Non Filter (NF), Basic Ultra Lights (UL), Newport, Marlboro (Red), Marlboro Menthol, Camel Filter, Camel Lights, Camel Ultra Lights, and two herbal cigarettes, Ecstasy and Dreams. The results for acrylonitrile were in very good agreement with data reported in the literature for 2R4F and 1R5F cigarettes. The levels of α-methacrylonitrile were not previously reported. The correlation between the levels of acrylonitrile and of α-methacrylonitrile with the (wet) total particulate matter (TPM) was evaluated. Although the levels of acrylonitrile and of α-methacrylonitrile in mainstream smoke depend on the TPM values, the correlation is not very strong, indicating that the nature of the cigarette blend and possible other factors in cigarette construction also influence their levels in smoke. The collection method used in this study allows the subsequent dissolution of VP in a much smaller volume of solvent compared to other methods that use impingers, allows the use of standard GC/MS autosamplers for liquid injection and simple addition of internal standards compared to the methods that use gas bags, and allows a simple and immediate collection of VP as it leaves the Cambridge filter pad. These characteristics represent significant advantages versus other methods commonly used for VP analysis.

Inder order to determine Benzopyrene (BaP) in Mainstream and Sidestream Smoke, a Solid phase extraction (SPE) cartridge was used to isolate the BaP fraction from the total particulate matter of mainstream cigarette smoke and sidestream cigarette smoke and the BaP were measured by RP-HPLC with ultraviolet detection. The result showed that the recovery rate of BaP extracted is 94.5%, compared with the relative standard of 6.95%. The yields of BaP in mainstream smoke for Virginia cigarette are higher than those for blended cigarettes. The yields of BaP in sidestream smoke are much higher than those in mainstream smoke. The proposed method involves an solid phase extract and HPLC-UV analysis procedure. With this method, the BaP yields in mainstream and sidestream cigarette smoke can be measured fast, easily and precisely using readily available apparatus and instruments.

Cigarette Mainstream Smoke

A method for simultaneous determination of acetaldehyde, propionaldehyde, acrolein, and crotonaldehyde in gas phase of cigarette mainstream smoke by headspace gas chromatography-mass spectrometry was developed and validated. Gas phase components of mainstream cigarette smoke were extracted with methanol, and then the samples were separated on a DB 624 (60 m, 0.32 mm x 1.8 mm) column, analyzed with headspace gas chromatography-mass spectrometry, and quantified by isotope internal standard. The linearities of acetaldehyde, propionaldehyde, acrolein, and crotonaldehyde were good (R2>0.992). The recoveries of acetaldehyde, propionaldehyde, acrolein, and crotonaldehyde were between 78.5% and 115%. The relative standard deviations were less than 10%. The limits of detection and limits of quantitation were 0.014 μg/cigarette ~0.12 μg/cigarette and 0.045 μg/cigarette ~0.38 μg/cigarette, respectively. The method had advantage of high sensitivity, it did not require derivatization of 2,4-dinitrophenylhydrazine and avoided a large number of adverse reactions during the process of derivation to improve the accuracy of result, and it was suitable for quantitative analysis of four aldehydes in gas phase of cigarette mainstream smoke.

AbstractThis study describes the results regarding the evaluation of retention efficiency by humans of hydroxybenzenes (phenols) from mainstream cigarette smoke. Over twenty phenols were evaluated in the exhaled smoke of a commercial cigarette with 10.6 mg ‘tar’ [U.S. Federal Trade Commission (FTC) ‘tar’ is defined as the weight of total particulate matter minus nicotine and water]. The test was performed on ten human subjects. The exhaled smoke was collected using a vacuum assisted technique that avoids strain in exhaling the smoke. The study showed that the phenols were retained with high efficiency from cigarette smoke, typically above 80%. Only 4-ethylresorcinol, and C3-dihydroxybenzenes (C3 indicating any alkyl with three carbon atoms) were retained less efficiently with retention values around 70%. The high retention of this class of compounds was expected since phenols are polar compounds with relatively low molecular weights between 94 (for phenol) and 152 (for a propyl-dihydroxybenzene).
