Cigarettes � Determination of nicotine in total particulate matter from the mainstream smoke with an intense smoking regime � Gaschromatographic method

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.

AbstractThis study describes the results regarding the evaluation of retention efficiency by humans of benzene and toluene from cigarette smoke. The evaluated cigarette was a common 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 subjects. The exhaled smoke was collected using a vacuum assisted technique that avoids strain in exhaling the smoke. The study showed that benzene was retained at levels of 89% to 98%, and toluene was retained at similar levels, between 87% and 99%. The lower limits of retention for both benzene and toluene are unexpectedly low compared to the retention of bi-and tricyclic aromatic hydrocarbons, which have retentions from cigarette smoke above 95%. This is probably caused by the fact that monocyclic aromatic hydrocarbons are present practically only in the vapor phase of cigarette smoke and at considerably higher levels than bi- and tri-cyclic aromatic hydrocarbons which are present almost completely in the particulate phase of cigarette smoke.
