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.
Identification of sources of fine (PM0.15-1.15) and coarse aerosol in Mlada Boleslav in winter 2013
Pokorná, P. ; Hovorka, J. ; Mikuška, Pavel ; Křůmal, Kamil ; Píšová, M.
The bilinear receptor model Positive Matrix Factorization – PMF was used to apportion sources of fine (PM0.15 – 1.15) and coarse (PM1.15 – 10) aerosol in residential district of Mladá Boleslav. The PMF analyzed datamatrix of hourly values of mass and aerosol elemental composition for 27 elements for fine and coarse aerosol and OC/EC for fine aerosol.
Organic compounds in PM1 in Mlada Boleslav 2013 and Ostrava 2014 in winter season
Křůmal, Kamil ; Mikuška, Pavel ; Večeřa, Zbyněk
In this work the organic compounds and organic markers used for the identification of sources of aerosols were measured. Monosaccharide anhydrides and resin acids (emissions from biomass combustion) and polyaromatic hydrocarbons (emissions from traffic and incomplete combustion) were observed especially. Hopanes, steranes (traffic, coal combustion) and alkanes were next groups of analysed organic compounds.
statistical analyssis of chemical composition of urban aerosol PM1 in Brno and Šlapanice
Mikuška, Pavel ; Mikušková, M. ; Křůmal, Kamil ; Večeřa, Zbyněk ; Michálek, J.
Urban aerosol particles in the size fraction PM1 collected in Brno and Šlapanice in winter and summer campaigns in 2009 and 2010 were analysed for ions and metals. Statistical analysis of chemical composition of PM1 aerosols by using a factor analysis was applied to identify emission sources of urban aerosols in Brno and Šlapanice.
