Abstract
Aim The current study examined symptoms of irritation reported by non-smokers passively exposed to e-cigarette aerosols and their timing and association with the concentrations of volatile organic compounds (VOCs) produced. Methods 40 healthy non-smoking adults were exposed to e-cigarette aerosols for 30?min in a 35?m3 room. Second-hand e-cigarette aerosol (SHA) was produced by an experienced e-cigarette user using a standardized topography and two resistance settings (exposure 0.5 Ohm and 1.5 Ohm), in addition to a control session (no emissions). PM2.5 and PM1.0 were continuously measured over the duration of exposure, while Volatile Organic Compounds (VOCs) were recorded at 0, 15 and 30?min (t0, t15 and t30) of exposure. Each participant completed an irritation questionnaire at t0, t15, t30 of exposure and t60 (30?min post-exposure) on ocular, nasal, throat-respiratory symptoms of irritation and general complaints. Kruskal-Wallis H test for PM comparisons, repeated measures ANOVA for VOCs and Generalized Estimating Equations for symptoms of irritation and association with VOCs were used for statistical analysis. Results 20 males and 20 females, with a mean age of 24.6 years (SD?=?4.3) and exhaled CO?
