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.

Comparison of measured and modelled deposition rate of ozone to spruce forest in locality Bílý Kříž. Estimation of daily changes in deposition and stomatal flux of ozone into spruce forest.
Dynamics of Aerosol Number Size Distributions during an Experimental Campaign at the Bily Kriz Measuring Site
Ždímal, Vladimír ; Moravec, Pavel ; Smolík, Jiří ; Mikuška, Pavel ; Večeřa, Zbyněk ; Pokorný, Radek
This work aimed at studying the dynamics of atmospheric aerosol particle size distributions and interpreting it in connection to local concentrations of gaseous pollutants and basic meteorological parameters. Number size distributions had been monitored with high time resolution during an intense experimental campaign at a remote continental sampling site Bily Kriz. The site is located at the NE tip of the Czech Republic in the hilly region. The campaign had ben carried out at the end of June 2001. Several very interesting events were observed when formation of large amounts of new aerosol particles occured in the day time. Due to the behaviour of other measured parameters it was concluded that the so called "nucleation events" took place on a mesoscale region.
The study of influence of atmospheric pollutants on the determination of nitrous acid with the preconcentration in the cylindrical wet diffusion denuder
Motyka, Kamil ; Večeřa, Zbyněk ; Mikuška, Pavel
The effect of pollutants which commonly occur in polluted air on the chemiluminescent determination of nitrous acid with preconcentration in cylindrical wet diffusion denuder was investigated.
