Concentrations of monosaccharide anhydrides in PM1 and PM2.5 aerosol
Mikuška, Pavel ; Křůmal, Kamil ; Vojtěšek, Martin ; Večeřa, Zbyněk
Analysis of monosacharide anhydrides (levoglucosan, mannosan, galactosan) in two aerosol size fractions (PM1 and PM2.5) and comparison of concentrations during winter and summer campaigns in Brno and Šlapanice in 2009, identification of main emission sources.
Deposition ozone flux over a Norway spruce forest and correlation with
Zapletal, M. ; Cudlín, Pavel ; Chroust, P. ; Urban, Otmar ; Pokorný, Radek ; Edwards-Jonášová, Magda ; Czerný, Radek ; Janouš, Dalibor ; Taufarová, Klára ; Medlen, A. ; Večeřa, Zbyněk ; Mikuška, Pavel ; Skácel, F.
Measured and modelled results of ozone deposition and stomatal flux to a Norway spruce forest in locality Bílý Kříž in July and August 2008 were compared. Enhanced concentration of ozone decreased net ecosystem production, especially at higher temperatures and high intensity of global radiation.
Seasonal and spatial variations of concentrations of metals in atmospheric aerosol and street dust in Brno and Ostrava
Vojtěšek, Martin ; Mikuška, Pavel ; Ličbinský, R. ; Adamec, V. ; Křůmal, Kamil
Study of elemental composition of PM10 and PM2.5 aerosols and street dust was performed in two different seasons and at two urban sites in the Czech Republic. Two localities with different potential sources were chosen for the identification of aerosol sources.
Determination of organic compounds in PM1 in Brno and Šlapanice
Křůmal, Kamil ; Mikuška, Pavel ; Vojtěšek, Martin ; Večeřa, Zbyněk
Monosaccharide anhydrides, polyaromatic hydrocarbons, hopanes, steranes and monocarboxylic acids were analysed in PM1. Contribution deals with extractions of these compounds from filters, preparations of samples, analyses by GC/MS and discussions of results of analysis.
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.
Monosaccharide anhydrides in PM1 and PM2.5 aerosol in urban areas
Křůmal, Kamil ; Večeřa, Zbyněk ; Mikuška, Pavel
Contribution deals with comparison of concentrations of monosacharide anhydrides (markers for biomass combustion) in Brno and Šlapanice at two seasons (winter and summer) and discussion about their emission sources.
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).
