Analysis of water-soluble fraction of metals in atmospheric aerosols using a semi-continuous system
Mikuška, Pavel ; Vojtěšek, Martin ; Večeřa, Zbyněk ; Křůmal, Kamil
Description of semi-continuous system for on-line detection of water-soluble fraction of metalls in atmospheric aerosols with time resolution of 30 min. Fe3+, Co2+, Cu2+ were selected as model metals.
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.
Seasonal variations of concentrations of metals in particulate matter and street dust in Brno and Ostrava
Vojtěšek, Martin ; Mikuška, Pavel ; Ličbinský, R. ; Adamec, V. ; Křůmal, Kamil
In this work a study of chemical composition of PM10, PM2.5 and street dust was performed at two urban sites in the Czech Republic in years 2009 and 2010. The first one is in the city center with high traffic density and the second is situated near steelworks.
Study of atmospheric aerosol in Brno and Šlapanice
Mikuška, Pavel ; Vojtěšek, Martin ; Křůmal, Kamil ; Večeřa, Zbyněk
Contribution deals with comparison of chemical composition of atmospheric aerosols (size fraction PM1) and identification of emission sources of aerosols in large (Brno) and small city (Šlapanice).
Concentration of elements in atmospheric aerosol and street dust in Brno and in Ostrava
Vojtěšek, Martin ; Mikuška, Pavel ; Ličbinský, R. ; Adamec, V. ; Křůmal, Kamil
Contribution deals with measurement of atmospheric aerosols (size fractions PM2.5 and PM10) in Brno and Ostrava and with comparison of concentration of elements in aerosol and street dust in Brno and Ostrava; effect of different potential sources is discussed.
Analysis of molecular markers from biomass combustion
Křůmal, Kamil ; Mikuška, Pavel ; Vojtěšek, Martin ; Večeřa, Zbyněk
This work compare PM1 and PM2,5 concentrations of levoglucosan, mannosan and galactosan in Brno (370 000 inhabitants) and Šlapanice (6 000 inhabitants) in winter and summer months. These compounds were analyzed by GCMS.
Mass distribution of atmospheric aerosols of size fractions PM1, PM2.5 and PM10
Vojtěšek, Martin ; Mikuška, Pavel ; Večeřa, Zbyněk ; Adamec, V. ; Ličbinský, R. ; Huzlík, J.
The mass concentration of PM1, PM2.5 and PM10 and temporal changes of PM2.5 were measured. The effect of traffic was examined.
Determination of peroxyacetylnitrate in air using a chemiluminescence aerosol detector
Mikuška, Pavel ; Bružeňák, L.
Chemiluminescent method of peroxyacetylnitrate detection in air using a CLAD and separation of interfering compounds (NO2, O3) provides fast, sensitive and specific determination of PAN with detection limit of 10 ppt and time resolution of 3 min.
Semi-continuous analysis of NH4+ in atmospheric aerosol and ammonia in air
Mikuška, Pavel ; Kapoun, M. ; Večeřa, Zbyněk
A combination of diffusion wet denuder and continuous aerosol collector provides continuous analysis and study of ammonia distribution between gaseous and aerosol phases.
