Křůmal, Kamil; Večeřová, Kristýna; Holišová, Petra; Urban, Otmar; Pallozzi, E.; Guidolotti, G.; Calfapietra, C.; Večeřa, Zbyněk
2015 - Czech
In this work three different techniques (1 online and 2 offline) for determination of monoterpenes in forest were compared. Monoterpenes were determined by PTR-MS (Proton Transfer Reaction Mass Spectrometer), cylindrical wet effluent diffusion denuders and tenax tubes. V této práci porovnávány tři různé techniky (1 online a 2 offline) pro stanovení monoterpenů v lese. Monoterpeny byly stanoveny pomocí PTR-MS, difúzních denuderů se stékajícím filmem kapaliny a tenaxových desorpčních trubiček.

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).

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.

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.
2014 - Czech
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.

2014 - Czech
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. V rámci tohoto výzkumu byly stanoveny celkové obsahy a biodostupné podíly vybraných kovů v pouličním prachu, městském aerosolu a emisích ze spalování biopaliva. Extrakční roztoky simulující tělní tekutiny vykazovaly značně odlišnou extrakční schopnost.
