Organic compounds in PM1 in Ostrava and Mlada Boleslav in winter season
Křůmal, Kamil; Mikuška, Pavel; Večeřa, Zbyněk
2015 - Czech
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. V této práci byly měřeny organické sloučeniny a markery, které slouží pro identifikaci zdrojů atmosférických aerosolů. Byly analyzovány anhydridy monosacharidů (emise ze spalování biomasy), polyaromatické uhlovodíky (emise z dopravy a nedokonalého spalování), hopany a sterany (doprava, spalování uhlí) a alkany.

Extraction of selected mercury compounds for speciation analysis by RP-HPLC-UV-CVG-QTAAS
Kolorosová, A.; Linhart, O.; Kratzer, Jan; Červený, V.
2015 - Czech
Extraction of selected mercury compounds (Hg+II, methylmercury, ethylmercury and phenylmercury) is studied using fish tissue samples. HPLC is employed for speciation, whereas UV-photochemical cold vapor generation coupled to atomic absorption is used for detection. Práce se zabývá extrakcí studovaných specií rtuti (Hg+II, methylrtuť, ethylrtuť a fenylrtuť) z tkání ryb a jejich stanovením pomocí HPLC, UV-fotochemického generování studené páry Hg a AAS s křemennou detekční trubicí (RP-HPLC-UV-CVG-QTAAS).

SMV-2015-706: Tests of apparatus for determination of 3H and 14C in air
Večeřa, Zbyněk
2015 - Czech
Testing of ”V3H14C” apparatus designed for 3H and 14C sampling from the air. The samples are captured into sorbents, silica gel for 3H (THO, T2O), and sodium hydroxide for 14C (14CO2) that are subsequently in laboratory analyzed for quantification of radioactive emissions of 3H and 14C from nuclear power plants e.g. Testování a vývoj zařízení řady ”V3H14C”, která jsou určena k odběru vzorků 3H a 14C ze vzduchu. Vzorky se zachycují do sorbentů, sorbentem pro 3H (THO, T2O) je silikagel, sorbentem pro 14C (14CO2) je vodný roztok 3M hydroxidu sodného. Získané vzorky jsou určeny k následné laboratorní analýze. Analýzou zjištěné hodnoty aktivit odebraných vzorků slouží ke stanovení bilance vypouštěného 3H a 14C např. z jaderných zařízení.

statistical analyssis of chemical composition of urban aerosol PM1 in Brno and Šlapanice
Mikuška, Pavel; Mikušková, M.; Křůmal, Kamil; Večeřa, Zbyněk; Michálek, J.
2014 - Czech
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. Atmosférické aerosoly frakce PM1 odebrané v průběhu zimních a letních kampaní v roce 2009 a 2010 v Brně a Šlapanicích byly analyzovány na obsah kovů a iontů. Statistická analýza chemického složení PM1 aerosolů použitím faktorové analýzy byla využita při identifikaci emisních zdrojů PM1 aerosolů v Brně a Šlapanicích.

SMV-2014-719: Measurement of nanoparticles in air
Mikuška, Pavel
2014 - Czech
The study focused on the impact of inhaled nanoparticles on the health status of basic and secondary school pupils based on the measurements of concentration and size distribution of nanoparticles in the air using an aerosol spectrometer SMPS. The nanoparticles were measured in two schools in two small towns and in three schools in Brno. Traffic intensity in near vicinity of schools and children's health asthma problems were investigated too. Studie sledovala dopad inhalovaných nanočástic na zdravotní stav žáků základních a středních škol. Koncentrace a velikostní distribuce nanočástic ve vzduchu byla měřena pomocí aerosolového spektrometru SMPS. Měření nanočástic probíhalo ve 2 školách ve 2 menších městech a ve 3 školách v Brně. Byly sledovány také intensita dopravy v blízkém okolí škol a zdravotní problémy dětí (astma).

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. Bilineární receptorový model PMF byl použit pro rozlišení zdrojů jemného (PM0,15-1,15) a hrubého (PM1,15-10) aerosolu v obytné oblasti v Mladé Boleslavi. Model PMF analyzoval data z hodinových hodnot hmotnostní koncentrace PM a 27 prvků jemného a hrubého aerosolu a OC/EC jemného aerosolu.
