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.

This diploma thesis deals with the comparison of the development of nitrates and phosphates in various regions of the Czech Republic. The thesis contains of the description of the circulation of groundwater and its importance to the human society, the circulation of nitrogen and phosphorus and their occurrence in waters. Further, this thesis incorporates the description of the development and the way of observation of the concentration of nitrates and phosphates in groundwater. The selection of observational objects and used methods for the evaluation of the concentrations are described in the thesis. The aim of the thesis is the determination of trends of the concentrations of nitrates and phosphates during time periods and the statistical evaluation of the progress of the concentrations in regional cities of the Czech Republic. The next part of the thesis deals with the spatial analysis of the concentrations of nitrates and phosphates in the region of České Budějovice. This area was chosen for its great amount of the observational objects with a long time period of measuring.
