| Abstract [eng] |
While there is a rapid market transition to new nicotine containing products, the data on the environmental aerosol generated by these products is very sparse. The aim of the doctoral dissertation is to investigate the spatial and temporal dynamics of environmental aerosol generated by the novel nicotine containing products, its chemical composition and the impact on indoor air quality. For the first time, the quantitative indications were provided in dissertation to compare possible hazards caused by HTP versus majority researched pollution sources (conventional cigarettes, water pipe, incense, mosquito coils, etc.). No data was available on the time-resolved patterns of dispersion of aerosol in a room under varying environmental conditions. In this dissertation, temporal and spatial variations of exhaled HTP, EC and CC aerosol in a chamber, based on a highly time resolved aerosol concentration and particle size distribution measurements, were compared. The impact of HTP products on IAQ in real-life settings has not been investigated yet. The experiment in the real nightclub was conducted to supplement the results gained in the chamber. |
