Vliv textilního průmyslu na složky životního prostředí
Chocholáčová, Adéla
This bachelor thesis deals with the impacts of the textile industry on environmental components. The thesis is conceived as a research of the basic negative consequences of this industry. The thesis explains the basic concepts like fast fashion or textile industry. The work includes the negative impacts of natural and man-made fibres, the different stages of textile production, including the post-life cycle phase of the product. The thesis shows that the textile industry is one of the biggest polluters of the environment, especially through wastewater containing toxic chemicals. The case of wastewater is elaborated in detail using the case of Bangladesh. The thesis concludes by presenting ways in which the negative impacts can be mitigated in the future and also presents sustainable methods and materials that are already in use.

Jakost vody vybraných rybníků v povodí toku Vydrica
Krajči, Filip
The diploma thesis is focused on the assessment of water quality in two successive ponds located on the Vydrica stream in the Malé Karpaty mountains. The analysis and subsequent assessment of water quality is based on field monitoring associated with the collection of samples and their subsequent analysis in the laboratory. The literary research deals with the assessment of water quality, the distribution of water, the distribution of protected landscape areas, but also the methods of management of ponds and the susitability of given ponds from the point of view of fish breeding. The literature review also contains a description of field monitoring indicators and laboratory determinations. The methodological part describes the principles of establishing field research and analysis of monitored water samples in the laboratory and the characteristics of sampling sites. The results obtained by field measurements and subsequent laboratory analysis were evaluated based on STN 75 7221 and Government Regulation No. 269/2010 Coll. After the evaluation, it was found that the water achieved the worst results, especially in the field of indicators reflecting organic pollution (BOD5, CHSKcr). Also, the content of elements such as total nitrogen and total phosphorus reached levels exceeding the limits of the worst class. These facts can further help in the management of the designated areas or in revitalization works in the vicinity, which are planned in the near future.

Zhodnocení vývoje jakosti vody vybraných toků v povodí vodárenské nádrže Švihov na řece Želivce
Markovcová, Zuzana
The bachelor thesis deals with the evaluation of water quality in selected watercourses in the Švihov water reservoir catchment area and compares the results with those from the catchment area of the Lučický stream, which is located outside the Švihov reservoir catchment area. The first part of the thesis is devoted to a literature review addressing the issue of water pollution, eutrophication, pesticides, individual nutrients, and related legislative regulations. The second part of the bachelor thesis contains a brief characterization of the Švihov water reservoir catchment area and the Lučický stream catchment area, a description of the methodology, and the results of the evaluation of water quality in selected watercourses. The processed results from the Švihov reservoir catchment area and the Lučický stream catchment area were compared in terms of management in protective zones and outside of them. The obtained results were evaluated based on Czech Standard 75 7221 and Government Regulation No. 401/2015 Coll., as amended. The results demonstrated a clear correlation between flow rate and the amount of pollutants transported, with significantly lower transport rates recorded in dry years than in hydrologically average years. Regarding pesticides, it was found that the parent substance was only present in water immediately after application to agricultural land, while metabolites were found in both water and soil permanently. At the same time, relatively high concentrations of a pesticide metabolite that cannot be used today were also recorded.

Zhodnocení samočistící schopnosti vodního toku Bítýška
Vítová, Kristýna
The bachelor thesis deals with the evaluation of the quality and self-cleaning ability of the Bítýška watercourse in Vysočina. The theoretical part is devoted to the water management legislation of the Czech Republic, water quality including related problems, self-cleaning ability, wetlands and monitored water quality indicators. The next part characterizes the area of interest in terms of natural conditions and hydrology. The practical part describes in detail the collection of water samples, measurement of water quality indicators in the field and laboratory determination of chemical water analysis. The work concludes with an evaluation of the results obtained according to the relevant legislation and discussion. The results of laboratory analysis have demonstrated that the self-cleaning ability of watercourses was exhibited only for half of the monitored period and cannot be unequivocally confirmed. The findings revealed high concentrations of nitrate nitrogen, total phosphorus and chemical oxygen demand caused especially by draining under-cleaned water from root wastewater treatment plant into the watercourse.

Monitoring jakosti vody vybraného toku
Zálešák, Petr
The bachelor thesis focuses on the evaluation of water quality in the Velička River. The Velička is located in the Hodonín district in southern Moravia. Its total length is 40.2 km. Its source is on the western slope of Velká Javořina and flows into the Morava River near Strážnice. The water flow was monitored in eight profiles at two-month intervals for one year. The monitoring had two phases. The first phase consisted of taking a water sample and measuring some of the water quality parameters in the field using an instrument kit from Hach Company. These were indicators of pH, conductivity, oxygen content, and water temperature. The second phase was carried out in a laboratory by measuring the quality parameters from the water samples using a spectrophotometer. The concentrations of total phosphorus, sulphates, nitrate nitrogen, and chlorides were monitored. The quality of the water in the river was evaluated according to the ČSN 75 7221 standard and government regulation No. 401/2015 Coll. Total phosphorus was evaluated as the most unfavorable qualitative parameter.

Oil accidents anf theis effect on water quality.
Lebdušková, Helena ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
The basic aim of the thesis is descritpion of oil accidents, which are these days the normal part of our lives. I deal with the issue of oil extraction as a base material for petrol, oil and other oil-based products. The current methods of production make these accidents impossible to avoid. The biggest problems come from using large tankers to transport the oil, other problems bring oil processing and waste production. This thesis focuses on the assessment of oil accidents and their effects on water quality, as well as on the whole ecosystem. Keywords Oil, oil accident, water pollution

Revitalization variants assessment of the Maříž Castle park and alternative solution of park revitalization concept
KALVODOVÁ, Vanda
The result of the proposed diploma thesis on "Revitalization variants assessment of the Maříž chetau park and proposal of alternative solution of park revitalization concept" is a "own variant" and evaluation of the alternative solutions for the revitalization of the Maříž chateau park. The first variant is named "non-intervention variant", which describes a status of the chateau park in year 2009, before making any intervention for revitalization. The second variant is a "design variant", that planners worked out for the owner of the park. The last variant is the "own variant" processed by the author of this diploma thesis. Each variant is evaluated in cultural-historical, ecological, economical, and social and educational terms through SWOT analysis. The diploma thesis found that in a village of Maříž there is already partly revitalization of the greenery. The main problem is the surface water pollution by waste water at present. The waste water problem is processed within of alternative solution of park revitalization koncept.

Water quality development in Mladoticky Brook catchment area
Vacková, Zuzana ; Janský, Bohumír (advisor) ; Benešová, Libuše (referee)
Water quality was one of the biggest problems of environment in beginning of 90. of 20th century in the Czech republic. Since 90. the level of water quality was in czech rivers rapidly better. Mainly in big rivers have accomplished great changes. The small rivers haven't notice that rapid changes. The Czech republic, after entrance to the European Union have committed to comply with Directive 91/271/EEC reduce urban waste water and which should have big influence to water quality also in small rivers. During 90. industry technology, agriculture, cleaning technology of waste water etc. reached big development. Therefore the presumption is higher quality of water in the Czech republic since 90. Goal of the thesis is comparison of results from 1999-2000 with results from 2012- 2014 from Mladoticky brook catchment, which is lined up to small river catchments (79,77km2 ). From this comparison there is obvious trend, if conditions of the water quality are really better or not since 90. [33] Since 2012 to 2014 were taken 12 times samples from 11 profiles of water from Mladotice brook catchment and they were consequential chemically analyzed. The samples were evaluated according to ČSN 757221 and compared with results from 1999-2000. From comparison with data 1999-2000 and 2012-2014 was confirmed the...
