Analysis of waterpipe aerosol constituents in accordance with the ISO standard 22486.

ABSTRACT: This study analyzed commercial waterpipe tobacco products in accordance with the newly developed ISO 22486 as well as with commercial waterpipes and charcoals using the ISO 22486 puffing regime for comparison. The aerosols from these products were analyzed for their nicotine, humectant, tobacco specific nitrosamine, carbonyl, benzo[a]pyrene, and metal yields. Significant differences were observed among the waterpipe tobacco products when analyzed in accordance with the ISO standard 22486 and with different commercial waterpipes and charcoals. The concentrations of CO and benzo[a]pyrene observed in the consumers' configuration using the ISO 22486 puffing regime (with lit charcoal) were higher than those obtained with the ISO standard using electrical heating, with the yields for carbonyl compounds being lower or higher. The use of the recently published ISO standard for generating water pipe tobacco aerosols should be complemented with analysis by using the consumers' configuration. The necessity for this was demonstrated by the differences in CO and benzo[a]pyrene yields in the present work. It appears that the temperature (280°C) selected for electrical heating of waterpipe tobacco products in ISO 22486 is somewhat lower than that obtained with commercial charcoals, resulting in a generally lower yield of nicotine and total collected matter. In addition, there is a need to evaluate the contribution of commercial charcoals to the concentration of constituents in waterpipe aerosols. This is particularly true for compounds resulting from charcoal combustion, such as CO and benzo[a]pyrene.

Project description:IntroductionWaterpipe use remains popular among youth with the availability of flavored shisha tobacco being one of the main drivers of waterpipe use. Although waterpipe mainstream toxicant emissions are well understood, less is known about the carryover of flavorants such as vanillin, benzaldehyde, and eugenol. In this study, flavored waterpipe tobacco was analyzed for flavorants and nicotine, and subsequent carryover to mainstream smoke.MethodsFlavorants vanillin, benzaldehyde, and eugenol, and nicotine were quantified in vanilla-, cherry-, and cinnamon-flavored shisha tobacco by gas chromatography/flame ionization detector and subsequently in waterpipe mainstream smoke generated by a smoking machine. The setup allowed for sampling before and after the water-filtration step.ResultsFlavorant and nicotine content in smoke was reduced 3- to 10-fold and 1.4- to 3.1-fold, respectively, due to water filtration. Per-puff content of filtered waterpipe mainstream smoke ranged from 13 to 46 µg/puff for nicotine and from 6 to 55 µg/puff for flavorants.ConclusionsAlthough water filtration reduced flavor and nicotine content in waterpipe mainstream smoke, the detected flavorant concentrations were similar or higher to those previously reported in e-cigarette aerosol. Therefore, users could be drawn to waterpipes due to similar flavor appeal as popular e-cigarette products. Absolute nicotine content of waterpipe smoke was lower than in e-cigarette aerosol, but the differential use patterns of waterpipe (>100 puffs/session) and e-cigarette (mostly <10 puffs/session, multiple session throughout the day) probably result in higher flavorant and nicotine exposure during a waterpipe session. Strategies to reduce youth introduction and exposure to nicotine via waterpipe use may consider similar flavor restrictions as those for e-cigarettes.ImplicationsAlthough waterpipe mainstream smoke is well characterized for toxicants content, little is known about carryover of molecules relevant for appeal and addiction: flavorants and nicotine. This study shows that flavorant content of waterpipe mainstream smoke is comparable or higher than e-cigarette aerosol flavorant content. Regulatory action to address tobacco use behaviors targeting the availability of flavors should also include other tobacco products such as flavored shisha tobacco.
