Air pollution - invisible threat?
Šitinová, Kristina ; Zajíček, Miroslav (advisor) ; Louda, Jiří (referee)
This paper examines the influence of air pollution on humans. Suggesting the possible consequences of each action of air pollutants on human health but also the possible economic impacts of air pollution. It primarily exploers the effects of concentration of suspended particulate matter (PM10) on the incidence of chronic obstructive pulmonary disease. The response variable in the regression model serves to determine the effect of PM10 on the incidence of chronic obstructive pulmonary disease was a percentage share of patients with chronic obstructive pulmonary disease among the clients of the General Health Insurance Company in individual regions of the Czech Republic. Explanatory variables were the mean annual concentration of PM10 and gross added value per capita. The model suggests that there is a statistically significant positive correlation between the incidence of chronic obstructive pulmonary disease in the Czech Republic and PM10 concentrations.

Emissions of particulate matter in poultry farms
VACOVSKÝ, Miroslav
Among the considerable factors in poultry include climatic conditions, where the breeding takes place. This work focuses on the content of solid particles PM10 and PM2,5 occurring in this environment. These particles can negatively affect the health status of breeding and staff, ensuring the necessary care in poultry farming. Dust particles settle on the skin, where they have an irritant effect or are inhaled into the respiratory tract bodies of birds. These particles are transferred microorganisms causing a variety of diseases. It is therefore desirable to eliminate the amount of such particles to the maximum extent possible.

Rating mass concentration of airborne dust in the road transport depending on the type of pollution transport routes.
PÁVEK, Miroslav
In the thesis the values of air pollution re-suspended solid pollutants on the diameter of 10 micrometres (PM10) during the movement of vehicles of different categories of polluted roads routes. Measurements were carried out on three lines of transport operation of various vehicle categories as diverse weight and the type of pollution road. Measured values and analysis results show that the resulting air pollution in the vicinity of the road affects several factors. The main factors include the level and nature of the pollution of the road, then the distribution of impurities on the surface of the road, another factor is the overall traffic intensity and the way the brush options while driving the vehicle.

Comparative analysis of the regulation policies of large sources of air pollution in the Moravia-Silesia and in the Silesian Voivodeship
Děcká, Michaela ; Vojáček, Ondřej (advisor) ; Jílková, Jiřina (referee)
The aim of this thesis is to perform comparative analysis of the state policies of the Czech Republic and Poland aimed at reducing dust emissions from industrial and power generation sources of air pollution in the Moravia-Silesia and in the Silesian Voivodeship. The analysis is meant to facilitate improving the regulation requirements of these sources in both districts. The extent of regulation of the sources of air pollution in the Silesia Voivodeship influences the amount of dust emissions produced by such sources and, due the influence of the existence of cross-border transfer of emissions, this influences the concentration of particulate matter in the atmosphere in the Moravian-Silesian Region. The thesis arrives at the conclusion that the industrial and power generation sources of air pollution in the Czech Republic in the Moravian-Silesian Region faces stricter regulation requirements in comparison with similar sources in Poland in the former Silesian Voivodeship. Stricter conditions of regulation for Czech sources are the reason for the lower level of emissions and the resulting higher control costs such sources. The thesis concerns comparative analysis of the control costs a sample group of metallurgic and power generation plants in the Moravian-Silesian Region and in the Silesian Voivodeship.

Characterization of atmospheric particulate matter by diffusive gradient in thin film (DGT) technique
Gregušová, Michaela ; Dočekal, Bohumil
In this study, characteristics of heavy metal contamination in road dust collected from urban area with heavy traffic in Brno, Czech Republic was investigated. The DGT probes were exposed in aqueous suspensions of particulate matter for different time periods to monitor responses of the sample matter. The road dust and DGT sorption gels were decomposed by microwave assisted extraction and analyzed by inductively coupled plasma mass spectrometry for estimation of trace metals contents. The results revealed that the traffic appears to be responsible for the high levels of Cu, Pb, Ni and Sb and also that DGT technique, as alternative to conventional extraction procedures is a useful tool for characterization of metals mobility.
