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.
