Characterization of Metals in Atmospheric Aerosol
 Cigánková, Hana ; Ličbinský, Roman (referee) ; Vojtíšek,, Michal (referee) ; Krajčovič, Jozef (advisor)
The presented doctoral thesis deals with the characterization of elements in two size fractions of urban aerosol, which was sampled in all seasons on the terrace of the Institute of Analytical Chemistry of the CAS in Brno in 2018. The theoretical part of the thesis summarizes the basic information about the analysis and health risks of atmospheric aerosol and metals bound to aerosol. Furthermore, the work describes methods for determining the inhalation bioaccessibility of aerosol particles and methods used for the determination of oxidative potential. The first part of the thesis describes in detail the sampling and analysis of urban aerosol particles. The mass concentration of both aerosol size fractions and the total concentration of 21 elements were determined. The probable sources of the analysed elements were calculated using the enrichment factor and positive matrix factorization. The second part of the thesis deals with the determination of the oxidative potential of the aerosol and bioaccessible concentration of the analysed elements in three simulated lung fluids (deionized water, simulated alveoli fluid, Gamble solution). In addition to determining the oxidative potential of real samples, the oxidative potential of individual elements was also analysed. From the obtained results was calculated the probable contribution of the elements to the measured oxidative potential.
