Water quality analysis in the Mastník catchment area
Mrkva, Luboš ; Janský, Bohumír (advisor) ; Chalupová, Dagmar (referee)
The quality of surface water in the Czech Republic has changed distinctly in two last decades. The pollution of important rivers has been reduced radically. Small rivers in agricultural areas, however, remain problematic. There is a long-term absence of information about such rivers concerning the purity of water. Mastník, which flows through the agricultural area of Central Bohemian Uplands and as a right-hand side tributary flow into the Vltava River, is one of those rivers. Quality circumstances in catchment area were analysed on the basis of data about the concentration of selected indicators, which come from three monitored profiles of the State public enterprise Povodí Vltavy. The present state of surface water quality was specified by means of ČSN 75 7221. Further, the development of quality was observed since 1995 and the reliance of the concentration on the flow or the season of the year was rated. All the data, which were acquired about anthropogenic and natural pollution of the river, are very important for precautions, which lead towards the improvement of quality of water in rivers. It was discovered that the precautions, which are made in catchment area lead to the improvement of the quality of water in Mastník. If the present state should be retained, the remediation of waste water must be...

Development of air pollution in the selected area
BARTŮŠEK, Ondřej
This thesis presents a comparison of the development of the concentrations of nitrogen oxides and sulfur dioxide in the air in the Usti region. The work described generally air pollution and related terms such as the sources of pollution emission, immission and atmospheric deposition. The study also evaluated pollution nitrogen oxides and sutur dioxide in the Usti region. This work describes the methods that were used in the calculations and evaluations. It also deals with the selecting appropriate measuring stations to handle the development of the concentrations of these substances in the air. The aim of this work is to find trends in time series of concentrations of NOx and SO2 and statistical evaluation of development levels in selected cities Ústí Region. The next section is evaluated spatial analysis of the concentration of nitrogen oxides and sulfur dioxide in the air in the Ústí Region. This area was chosen primarily because it is characterized by significant air pollution.

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.
