Magnetometrical and spectrometrical analyses of fly ashes from the areas with emissonal air pollution mainly from automobile traffic (near Prague's D0 motorway) and from industry (near Ostrava's iron-mills) with a use of meteorological data
Hrušková, Gloria ; Petrovský, Eduard (advisor) ; Kletetschka, Günther (referee)
The content of analytical part of this thesis is the study of airborne dust samples collected in places with its higher concentration: by the Prague Ring (D0 motorway) and near the Ostrava's iron-mills. In both places, automobile transportation or industrial production are the primary sources of particulate matter emissions in the air. Received samples of PM1, PM2, PM10 a TSP filters were obtained by a standard air pollution monitoring procedure. This study examines the relationship between the magnetic parameters of the samples, their level of concentration of metals frequently present in emissions from these sources, the total mass of the dust fraction in the samples and the meteorological parameters (for Ostrava samples). The magnetic properties of the filters were investigated by magnetometric analyzes using a vibration sampling magnetometer. The concentrations of the metals were monitored by X-ray fluorescence spectrometer, the weight of parts of dust filtres was measured on laboratory scales.
Changes of volume activity of radon in soil gas in dependence on the meteorological parameters
Hrušková, Gloria ; Matolín, Milan (advisor) ; Jáně, Zdeněk (referee)
This work engages in radon in soil gas, measuring its volume activity and atmospherical influences on its volume activity. Atmospherical (or meteorological) influences are a pressure, temperature and moisture of the air, wind and its velocity, a condition of the sky and a rate of precipitation. The measurement results from the period 2000-2012 done by the Charles University in Prague, Faculty of Natural Science (The Institute of Engineer Geology, Hydrogeology and Applied Geophysics, Department of Applied Geophysics) in the radon comparisoning areas Cetyně, Bohostice, Buk were used for the assessment.
