The effective air quality management in the heavy polluted areas has to be based on high-quality monitoring with properly designed monitoring network and targeted measurements, which provided information required to source apportionment. The study aim was to apportion sources of atmospheric aerosol based on highly time resolved data of mass concentration of size segregated aerosol, its spatial variability, elemental composition and OC/EC at three localities in the Czech Republic in the years 2008 – 2010, 2012, 2013. According to the size fractions ratio arose the importance of PM1 source apportionment because of PM0.15-1.15 mean ratio to PM10, which comprised 85 % at the monitoring localities primarily in winter. The main sources of coarse fraction in winter were coal and biomass combustion in Březno by Chomutuv a Mladá Boleslav and road dust re-suspension in Ostrava-Ravanice and Bartovice. In summer dominated soil re-suspension and primary biological – bioaerosol in Březno by Chomutuv. The dominated source of fine fraction was in winter coal combustion Ostrava-Ravanice and Bartovice and biomass burning in Mladá Boleslav. From the above mentioned results arose, that the highly time resolved data are suitable for source identification of size segregated atmospheric aerosol and enable to evaluate representativeness of monitoring station location and measurement campaign.

Organic compounds in PM1 aerosol in Kladno-Svermov in winter 2017
Křůmal, Kamil ; Mikuška, Pavel ; Večeřa, Zbyněk
The work deals with the measurement of organic compounds and organic markers used for the identification of main aerosol sources in PM1 aerosol in a small town (Kladno-Švermov) near Prague. Monosaccharide anhydrides and resin acids (emissions from biomass combustion) were found especially. Polycyclic aromatic hydrocarbons (emissions from traffic and incomplete combustion), hopanes (traffic, coal combustion), steranes (traffic), saccharides and alkanes were other groups of analysed organic compounds.
