This dissertation applies its mind to the evaluation of five selected localities caused by slate mining in the area of the Low Jeseník, namely at point-blank range the Kružberk water reservoir and is based on the lichenological research and on the Czech Hydrometeorological Institute data. Two lacalities, 1 and 2 are located in the west side of the dam, the locality 3 is in the east side and the localities 4 and 5 are located to the south from the dam. From 2015 to 2016, during the ongoing research, there were determined 23 the most commonly ocuring tereristic lichen species. To the found vulnerable species belong, for example, Cladonia glauca or Cladonia ciliata. In the locality 3 the most occuring family Cladoniceae is mainly represented by Cladonia ciliata, Cladonia rangiferina and Cladonia arbuscula. Based on the results it was discovered that lichen species coming from the Cladoniceae family are the most frequently spread on the upper part of the localities, on the top of the slate slag heaps; but the slopes are prefered by sessile species. The slope posts are too extreme because of their enormous inclination and exposition. The tree storey was determined too together with frequency of woody plants incidence on the grounds of localities shielding. Full-grown trees expanded from the surrounding forest were especially found at the slag heap bases. Larix decidua was mostly observed, Betula pendula colonized slopes. On the bases of The Czech Hydrometeorological Institute data was the Kružberk dam area assessed relatively clear because it is the area protected against pollution and and is considered to be a fresh water resource. Air pollution made by NO2, SO2 and MP10 showed good results with low improving level from 2014 to 2015. There is made a suggestion to have the minimal management because there was not seen any negative human or animal influence to the lichen diversity and natural evolution of association has been going on. Large frequency of Cladoniceae was monitored in the locality 3 and so this locality is suggested for long-term monitoring of environment with chemical-physical methods and monitoring lichen diversity. The author developed her photo suplement and used here her own illustrations to easy determine the most common species occuring on the stone quarry. This appendix can be found at the end of the dissertation.

The thesis deals with photocatalysis of organic pollutants on UV-activated anatase particles, on UV-activated anatase particles with hydrogen peroxide and hydrogen peroxide itself. The measurement is carried out on a pilot plant UV photoreactor. The aim of the thesis is to determine the effectiveness of azo dyes and antibiotics degradation. The level of azo dyes and antibiotics degradation is measured by UV-VIS spectrometry.

The diploma thesis deals with photocatalytic degradation of organic polutants on water- suspended UV activated anatase particles. The measurements are executed on a pilot plant UV photoreactor and the aim the thesis is to figure out the time course of azo dyes degradation under different photoreactor settings and subsequently infer the effectivity of the photoreactor under different settings. The degree of the aze dyes degradation is evaluated via UV-VIS spectrometry.

This thesis is focused on the effect of ozone on ink-jet prints. The knowledge about print technologies, materials for ink-jet printing, influence of environmental factors on the prints degradation and the methods of print lifetime estimation are discussed in the theoretical part of the thesis. Test-charts of 108 samples of C, M, Y primary colours and their overprints were prepared. I used two types of papers designed for ink-jet printing. These samples were exposed the effect of ozone in various concentrations to perform an accelerated aging experiment. Optical density values, La*b* coordinates, colour difference values were calculated from the measured spectral data. Changes of colours of the ink due to ozone exposure were determined and discussed. The validity of the reciprocal law due to ozone exposure was studied, too. The reciprocal behaviour was not confirmed for both types of the studied papers.

Sulfonamides are antibiotics that are frequently used both in human and veterinary medicine. The combinations of abundant use of these antibiotics and their natural resistance to decay leads often to long term persistence in the environment. This accumulation, especially in living organisms, may lead to subsequent toxicosis. Also, presence of these antibiotic in nature poses problems with regard to the spread of genes for antibiotic resistance between potential pathogens. These facts led to an increase interest in studying the sulfonamide biodegradation and subsequent sulfonamide removal from the environment. In this work it was possible to isolate and characterize the microorganism Acinetobacter sp. strain 49. This microorganism was able to biodegrade under right conditions sulfamethoxazole with 80 % efficiency. Sulfamethoxazole is one of the most commonly found sulfonamide in the nature.

Good soil condition belongs to the basic requirements of well-ballanced environment. That is why the soil has to correspond to hygienic requirements and be protected against substances harmful to human health, e.g. toxic materials, germs of transmissible illnesses and parasites. The most common cause of soil contamination is anthropogenic incidence. Contaminated soil belongs to waste and has to be removed in a proper way. is A special way of waste removal is soil decontamination. Its goal is to remove harmful substances and regain the original use of the soil.
