Metal concentrations in urban aerosol in Brno and in exhaust fumes
 Coufalík, Pavel ; Mikuška, Pavel ; Křůmal, Kamil ; Vojtíšek, M. ; Matoušek, Tomáš ; Večeřa, Zbyněk
Total metal concentrations in aerosol samples and exhaust fumes as well as the bioaccessibility of metals in simulated lung fluids were determined. The extraction in vitro seems not to be dependent on the surface tension of extraction solution.

Metals concentrations in urban aerosol and in exhaust emission
 Coufalík, Pavel ; Mikuška, Pavel ; Křůmal, Kamil ; Vojtíšek, M. ; Matoušek, Tomáš ; Večeřa, Zbyněk
Total metals concentrations in aerosol samples and exhaust fumes as well as the bioaccessible proportions of metals were determined. The bioaccessibility of metals in vitro should be assessed according to the extraction in simulated lung fluids with a low surface tension.

Organic compounds in PM1 aerosol in Celakovice in winter 2015
 Křůmal, Kamil ; Mikuška, Pavel ; Coufalík, Pavel ; Večeřa, Zbyněk
In this work the organic compounds and organic markers used for the identification of sources of aerosols were measured in PM1 in a small town Celakovice.

Composition of particles and gases in emissions of spark ingnition engines: effect of operation cycles and alcohol fuels
 Mikuška, Pavel ; Křůmal, Kamil ; Coufalík, Pavel ; Vojtíšek-Lom, M. ; Beránek, V. ; Štolcpartová, Jitka ; Večeřa, Zbyněk
Chemical composition of particles and gaseous compounds in emissions of spark-ignition engine depends on operation cycle and the method of formation of the fuel mixture. Particulate emissions (both particle mass and especially particle number concentration) were significantly higher at engine with the direct formation of mixture (engine DISI) than at engine with indirect formation of the mixture (MPI), and were affected both by the operating conditions and by the fuel used.

Organic compounds in PM1 aerosol in the Central Bohemian Region in the Czech Republic
 Křůmal, Kamil ; Mikuška, Pavel ; Coufalík, Pavel ; Večeřa, Zbyněk
Contribution summarizes the concentrations of monosaccharide anhydrides, resin acids, methoxyphenols, monosaccharides, disaccharides, sugar alcohols, alkanes, hopanes, steranes and polyaromatic hydrocarbons in PM1 aerosols in small town Celakovice in winter. According to concentrations of organic markers, the identification of emission sources in Celakovice is discussed.

Organic compounds on dust particles in emissions of gasoline cars
 Mikuška, Pavel ; Křůmal, Kamil ; Coufalík, Pavel ; Večeřa, Zbyněk ; Vojtíšek, M.
In this study, chemical composition of emissions of two gasoline cars (Ford-Focus; DISI and Skoda Fabia; MPI) was compared. Two different fuels and working cycles were applied during experiments.

Extraction of bioavailable proportion of metals in aerosol and street dust
 Coufalík, Pavel ; Mikuška, Pavel ; Křůmal, Kamil ; Večeřa, Zbyněk ; Vojtíšek, M. ; Matoušek, Tomáš ; Zvěřina, O.
The determination of total contents and bioavailable proportions of selected metals in street dust, urban aerosol and emissions from biofuel combustion was performed in this research. Extraction solutions simulating body fluids evinced significantly different extraction ability.

Monosaccharide anhydrides in atmospheric aerosols - optimization of separation and detection by means of LC-MS technique
 Čmelík, Richard ; Coufalík, Pavel ; Mikuška, Pavel
We report a simple analytical method, based on high-performance liquid chromatography with mass spectrometric detection, which was developed and utilized to determine monosaccharide anhydrides in atmospheric aerosols.
