Analysis of Organic Markers for Identification of Sources of Atmospheric Aerosols
Křůmal, Kamil ; Chýlková, Jaromíra (referee) ; Vávrová, Milada (referee) ; Smolík,, Jiří (referee) ; Večeřa, Zbyněk (advisor)
In this work the organic markers that serve for identification of sources of aerosols are monitored. Theoretic part deals with detailed survey of organic markers emitted from the most significant sources of atmospheric aerosols (biomass combustion, combustion of fossil fuels and traffic) as well as with sampling of aerosols and analysis of organic markers by analytical techniques. Monosaccharide anhydrides (emissions from biomass combustion) and polyaromatic hydrocarbons (emissions from traffic and incomplete combustion) were observed especially. Hopanes and steranes (traffic, coal combustion) and fatty acids (cooking) were next groups of monitored organic markers. Markers were studied mainly in size fraction PM1 because this fraction of aerosols is the most harmful to human health. Aerosols were sampled in two seasons (winter and summer) in two towns in 2009. Higher concentrations of aerosols and organic compounds were found in winter season, which resulted from increased combustion of biomass, coal and other organic material while traffic was the most significant source of aerosols in summer.

Analysis of saccharides and markers of wood combustion in atmospheric aerosols
Kubátková, Nela ; Mravcová, Ludmila (referee) ; Mikuška,, Pavel (advisor)
Diploma thesis deals with the analysis of saccharides and markers of biomass and wood combustion in atmospheric aerosol, PM2,5. Theoretic part is focused on general characterisation of atmospheric aerosols and on the properties, sources and analysis methods of selected analysed organic compounds. The experimental part is focused on the optimization of method for simultaneous analysis of saccharides and tracers from biomass and wood combustion. Optimization of method includes selection of solvent for the extraction of compounds and optimization of derivatization process and GC/MS analysis. The optimized method was then applied for the analysis of selected compounds in real aerosol samples in the size fraction PM2.5. The concentrations of analysed compounds were compared in term of sampling seasons.

Organic compounds in PM1 aerosol in Kladno-Svermov in winter 2017
Křůmal, Kamil ; Mikuška, Pavel ; Večeřa, Zbyněk
The work deals with the measurement of organic compounds and organic markers used for the identification of main aerosol sources in PM1 aerosol in a small town (Kladno-Švermov) near Prague. Monosaccharide anhydrides and resin acids (emissions from biomass combustion) were found especially. Polycyclic aromatic hydrocarbons (emissions from traffic and incomplete combustion), hopanes (traffic, coal combustion), steranes (traffic), saccharides and alkanes were other groups of analysed organic compounds.
