Atmospheric deposition of substances in the Czech Republic and abroad
BARTŮŠEK, Ondřej
This thesis is focused on atmospheric deposition of substances in the Czech Republic and abroad. There are also briefly explained concepts such as source pollution emissions and air pollutants, which are depended on each other and which are closely linked with atmospheric deposition. There is also explained the process of formation of atmospheric deposition. There are also described in detail the types of atmospheric deposition, their structure, removing a procedure for estimating the size of atmospheric deposition. To get an idea of the work the values of atmospheric deposition in Europe, China, North America and in the last row in the Czech Republic, where is briefly described the trend of atmospheric deposition. Furthermore, there are station network in the Czech Republic. The last part of the thesis deals with the development of the atmospheric deposition of sulfur, nitrogen and hydrogen ions in the Czech Republic and at certain stations.
A comparison of the development of atmospheric deposition of nitrogen and phosphorus in different regions of the Czech Republic
SUCHÁ, Jitka
This thesis engages a comparison of the development of atmospheric deposition of nitrogen and phosphorus in different regions of the Czech Republic. The work explains the formation of atmospheric deposition and related terms such as the source of pollution, emissions, air pollution and nitrogen oxides. There are stated types of atmospheric deposition, sampling procedure and the process of determining the size of atmospheric deposition. This work describes the methods that were used in the calculations and evaluations. It also deals with the selection of suitable measuring stations for processing the development of atmospheric nitrogen deposition. The atmospheric deposition of phosphorus were not measured in the territory of the Czech Republic in the period from 2000 to 2010. The aim of this work is to find trends in time series of concentrations of NOx and statistical evaluation of the development of atmospheric nitrogen deposition. For these chapters were selected concentration of nitrogen oxides in the regional towns of the Czech Republic. In the chapter of spatial analyzes of the concentration of nitrogen oxides is selected Ústecký kraj, mainly due to the fact that this area is characterized by significantly high atmospheric deposition of nitrogen and total air pollution. A therm the Black Triangle is often used for this location.
Atmospheric deposition of nitrogen and phosphorus in the Czech republic and round the world.
SUCHÁ, Jitka
This bachelor thesis is focused on the atmospheric deposition of nitrogen and phosphorus in the Czech Republic and round the world. For easier understanding of atmospheric deposition in the thesis there are shortly explained terms such as the source of pollution, emissions and air pollutants, which are interdependent and often interact. There are presented different types of atmospheric deposition, their detailed classification, their collection and the process of determining the size of atmospheric deposition. Furthermore, this thesis gives the current value of atmospheric deposition in European and non European countries and the values in the Czech Republic, where the trend of atmospheric deposition from the fifties to the present is shortly described. The thesis presents the station network in the Czech Republic, its functions and methods of data collection, which are still used to evaluate the air quality situation in Europe in the EMEP programme, where you can find information about other European countries. Then the values of atmospheric deposition of nitrogen and phosphorus in the U.S., especially on the east coast and central parts of the United States of America, and China are presented. The last part of the thesis is focused on atmospheric nitrogen deposition value development in the Czech Republic selected, more or less affected areas in the Czech republic.
The effect of deforestation of mountain catchments on surface water quality
TOMKOVÁ, Iva
This bachelor thesis summarizes (i) changes in soil and surface water composition in mountain catchments after their deforestation due to by bark beetle outbreak, windstorm, and timber harvesting, and (ii) monitoring of environmental parameters necessary for evaluation and quantification of these changes.

Comparison of measured and modelled deposition rate of ozone to spruce forest in locality Bílý Kříž. Estimation of daily changes in deposition and stomatal flux of ozone into spruce forest.
Atmospheric deposition in the vicinity of the limestone-quarry Čertovy schody
Špičková, Jitka ; Dobešová, Irena ; Vach, Marek ; Burian, Miloš ; Skřivan, Petr
Atmospheric precipitation samples were collected in the Bohemian Karst, (30 km SW from Prague, Czech Republic) at six localities in the vicinity of the limestone-quarry Čertovy schody during years 1996-2003. Samples were analyzed for major components (Na+, K+, Mg2+, Ca2+, F-, Cl-, NO3-, HCO3-, SO42-) and trace metals (Cu, Mn, Fe, Zn, Pb, Be, As, Sr, Cd, Al, Cr). Deposition fluxes were calculated from more than 10 000 elemental analyses of samples collected monthly. The fluxes of monitored substances show temporal and spatial variability. The most marked attribute is the strong affection by local emission sources confirmed by the investigation of seasonal variability, temporal trend and correlation analysis.
Occult precipitation as a important contribution to the atmospheric deposition in the selected mountain and urban regions of the Czech Republic
Tesař, Miroslav ; Šír, Miloslav ; Fottová, D.
The deposition of the water droplets from wind-driven fogs and low clouds onto the earth surface - mostly on the vegetation cover - represents important mass input in many mountainous regions. Occult precipitation influences the air quality also in the urban areas because a very complex surface of these regions and the high level of the pollution load result into the high deposition of the occult precipitation.
Atmospheric Deposition 2004
Šír, Miloslav ; Tesař, Miroslav
Proceedings summarises 19 contributions presented in the framework of the Workshop "Atmospheric Deposition 2004" that was focused on the air-born pollution, its monitoring, modeling, trends and development, impacts on the natural environment and the use of the obtained findings in the decision making sphere.
