Ways for minimizing the negative effect tobacco aerosol components during passive smoking

Introduction. There are reported air quality assessment findings in enclosed spaces in experimental conditions using two kinds of nicotine-containing products - cigarettes and electronic nicotine delivery system (ENDS), seem to be the most common types of smoking.

Мaterial and Methods. In the process of the experiment concentrations of tobacco aerosol components, i.e.: 12 chemicals and two aerosols were measured. Studies were carried out in isolated rooms under monitored microclimate parameters and uniform air mixing. Groups of volunteers using cigarettes or electronic nicotine delivery systems and the control non-smoker group participated in the study; everybody gave their informed consent for participation in the experiment. Control of background indices for comparison of air quality in rooms where tobacco products were being smoked was carried out.

Results. Our studies allowing to identify chemicals evolving into the air of enclosed rooms where “PARLAMENT Aqua Blue” cigarettes were smoked or electronic tobacco delivery systems “CRICKET Classic 3.0” were used,  to estimate total amount of chemicals in air. Prevailing chemicals affecting human health, which can be recommended for the use in calculations and air study of enclosed rooms exposed to tobacco aerosol, were identified. Estimated values of adverse chemical concentrations, air flow and air expenditure rate, resulting from experimental data allow designing ventilation system with regard to hygienic requirements based on maximum allowable concentration values for atmospheric air.

Conclusions. Suggested recommendations on calculation of ventilation parameters to produce comfortable human environment in passive smoking conditions will improve air quality in public buildings.
