2024-12-01 00:39	Inorganic components of PM2,5 aerosol in the area of children's sanatorium with speleotherapy Alexa, Lukáš ; Horká, M. ; Mikuška, Pavel ; Křůmal, Kamil ; Hlaváčková, Hana ; Cigánková, Hana ; Coufalík, Pavel ; Zmrzlá, H. ; Hegrová, J. ; Ličbinský, R. ; Vít, R. ; Huzlík, J. ; Mbengue, Saliou ; Prokeš, Roman Filters with collected aerosols were analysed for anions, cations and elements. Measurement of particulate elements with high time resolution was performed only during winter campaign. Mobile measurement of particle number concentration was provided during both (winter and summer) campaigns in the village, sanatorium building and Císařská cave. Detailed results of aerosol components will be presented. Detailed record
2024-12-01 00:39	Characterisation of Atmospheric aerosols in air aroun the children's sanatorium Mikuška, Pavel ; Křůmal, Kamil ; Hlaváčková, Hana ; Alexa, Lukáš ; Coufalík, Pavel ; Cigánková, Hana ; Zmrzlá, H. ; Hegrová, J. ; Ličbinský, R. ; Vít, R. ; Huzlík, J. ; Mbengue, Saliou ; Prokeš, Roman ; Horká, M. Higher aerosol concentrations during the winter campaign than during the summer campaign indicate greater air pollution during heating period. Both local and regional emission sources may contribute to the pollution, and the contribution of long-range transport of aerosols cannot be neglected. The main emission sources of pollution in winter were identified as the burning of wood and coal, mainly for domestic heating. Detailed record
2024-11-26 10:48	Stanovení rychlých změn koncentrací biogenních těkavých organických sloučenin pomocí difuzního denuderu Křůmal, Kamil ; Handlířová, G. ; Mikuška, Pavel Hlavním tématem příspěvku je optimalizace podmínek pro odběr vzorků biogenních těkavých organických látek (BVOC) v ovzduší pomocí denuderu se stékajícím filmem kapaliny (WEDD) s následnou analýzou odebraných vzorků pomocí plynové chromatografie ve spojení s hmotnostní spektrometrií (GC-MS).

2024-11-02 00:00	MSB 2024. 40th International Symposium on Microscale Separations and Bioanalysis. Program and Abstract Book Foret, František ; Lavická, Jana ; Přikryl, Jan The Proceedings included abstracts of 61 oral and 53 poster presentations. The attached conference proceedings, edited by highly cited scientists, documents the quality of the meeting. Detailed record
2024-10-13 00:00	Development of a novel hydride atomizer based on atmospheric pressure glow discharge for atomic absorption spectrometry Vlčková, Nikol ; Svoboda, Milan ; Coelho, Gilberto ; Kratzer, Jan ; Greda, K. A novel type of atmospheric pressure plasma discharge was developed to serve as hydride atomizer derived from the shape of the quartz body of a conventional quartz tube atomizer used in AAS. However, instead of resistive heating of the optical arm, two electrodes were inserted in its central part to sustain an APGD-like discharge (0.5 kV, 30 mA). Atomization of As, Se and Sb hydrides was optimized. Its performance is comparable to that of QTA or DBD atomizers. Detailed record
2024-10-13 00:00	Přenosný kapalinový chromatograf a analýza nebezpečných látek Šesták, Jozef ; Lunerová, K. ; Vaněk, A. ; Hamerník, I. Funkční vzorek přenosného HPLC vlastní konstrukce byl testován pro stanovení vybraných mykotoxinů a cyanotoxinů, výbušnin, simulantů BCHL, PAHů a drog, na dalších aplikacích se pracuje. Současná spolupráce s firmou INGOS s. r. o. má za cíl dovést tento koncept do komerčně dostupné podoby. Detailed record
2023-12-06 00:37	Charakterizace prvků v městském aerosolu Hlaváčková, Hana ; Cigánková, Hana ; Mikuška, Pavel ; Hegrová, J. Prvky jsou důležitými složkami atmosférických aerosolů. Těžké kovy jsou známé látky znečišťující životní prostředí díky své toxicitě a schopnosti akumulovat se v lidském těle. Těžké kovy mohou vykazovat toxikologické účinky i ve stopových množstvích. Detailed record
2023-12-06 00:37	Simultaneous online determination of nitric acid and nitrates in ambient air Alexa, Lukáš ; Čmelíková, D. ; Cigánková, Hana ; Mikuška, Pavel The innovated method for the simultaneous online determination of HNO3/NO3- in ambient air was developed. Due to high sensitivity of CLD (LOD = 5.1 nM in water solution, 3 s/n) no preconcentration method is required. The online methods were compared with the results obtained with the offline method based on sampling using filters and dry denuders (DD) covered by 0.5% NaF with subsequent analysis by ion chromatography (model ICS-2100, Dionex, USA) and capillary electrophoresis (model Agilent 7100, Agilent Technologies, USA).

2023-12-06 00:37	Forest springs, a safe source of drinking water? Mikuška, Pavel ; Alexa, Lukáš ; Kouřilová, S. ; Cigánková, Hana ; Křůmal, Kamil ; Itterheimová, Petra ; Kubáň, Petr ; Matoušek, Tomáš ; Barešová, Magdalena ; Pivokonský, Martin Water from 25 forest springs was characterized for basic physical parameters and chemical and bacteriological composition. Chemical composition was mostly within limits for drinking water, but bacteriological results indicate faecal pollution of water in majority studied springs. Detailed record
2023-11-12 00:02	CECE 2023. 18th International Interdisciplinary Meeting on Bioanalysis Foret, František ; Lavická, Jana ; Přikryl, Jan This year the Proceedings included abstracts of 27 oral and 33 poster presentations. The attached conference proceedings, edited by highly cited scientists, documents the quality of the meeting. Similarly to the previous years the lectures were given by outstanding, highly cited, scientists. The list of speakers as well as more detailed information about the conference can be found on its permanent web at www.ce-ce.org. Detailed record
