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?ª+min in a 35?ª+m(3) 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). PM(2.5) and PM(1.0) were continuously measured over the duration of exposure, while Volatile Organic Compounds (VOCs) were recorded at 0, 15 and 30?ª+min (t(0), t(15) and t(30)) of exposure. Each participant completed an irritation questionnaire at t(0), t(15,) t(30) of exposure and t(60) (30?ª+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?ª+=?ª+4.3) and exhaled CO?ª+ª+7?ª+ppm participated. PM concentrations in both experimental sessions were higher than the Control (p?ª+ª+0.001). The most commonly reported symptoms were burning, dryness, sore throat, cough, breathlessness and headache. During both experimental sessions, ocular, nasal, throat-respiratory symptoms and general complaints increased significantly (p?ª+ª+0.05). Ocular and nasal symptoms returned to baseline by t(60) (p?ª+>?ª+0.05) while throat-respiratory symptoms were still significantly higher at t(60) (p?ª+=?ª+0.044). VOCs were significantly associated with reported nasal and throat-respiratory symptoms in both experimental sessions (p?ª+ª+0.05). CONCLUSION: A 30-min exposure to SHA provoked symptoms of sensory irritation and general complaints that lasted up to 30?ª+min after the exposure and were positively associated with the concentrations of the VOC mixture emitted" |
