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.
Organic compounds and markers from coal combustion in different types of boilers used for household heating
Křůmal, Kamil ; Mikuška, Pavel ; Horák, J. ; Hopan, F.
Organic compounds (polycyclic aromatic hydrocarbons) and organic markers (hopanes) used for the identification of aerosol emission sources were measured in emissions from the combustion of hard and brown coal. Coal was combusted in different\nboilers used for residential heating in the Czech Republic, i.e., overfire boiler, boiler with down-draft combustion and automatic boiler.
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.

Comparison of concentrations of organic compounds in PM1 aerosol in Brno and Šlapanice
Křůmal, Kamil ; Mikuška, Pavel ; Večeřa, Zbyněk
In this work the organic compounds and organic markers used for the identification of sources of aerosols were monitored. Monosaccharide anhydrides are emitted from biomass combustion, polyaromatic hydrocarbons from traffic and incomplete combustion, hopanes from traffic and coal combustion, steranes from traffic and fatty acids from cooking.
Analysis of hopanes and steranes in PM1 in Brno and Šlapanice
Křůmal, Kamil ; Mikuška, Pavel ; Vojtěšek, Martin ; Večeřa, Zbyněk
Contribution deals with analysis of hopanes and steranes in Brno and Šlapanice. Steranes are markers for traffic and hopanes for traffic and coal combustion.
Polyaromatic hydrocarbons, hopanes and steranes in PM1 in Brno and Šlapanice
Křůmal, Kamil ; Mikuška, Pavel ; Vojtěšek, Martin ; Večeřa, Zbyněk
Contribution deals with comparison of concentrations of polyaromatic hydrocarbons, hopanes and steranes in Brno and Šlapanice at two seasons (winter and summer) and identification of emission sources of aerosols in these locations.
