Regulatory instruments of cycloturism in specially protected areas
Kostříková, Markéta ; Máca, Vojtěch (advisor) ; Kotecký, Vojtěch (referee)
Cyclotourism is one of the most popular recreational activities nowadays, and specially protected areas are often chosen as a preferred destination. This thesis covers the issues that can arise from excessive tourist use of the area, or by not complying with the rules set by the law, or by an administration of the protected area. Cyclotourism has a considerate impact on the environment. The most affected components are vegetation, soil, aquatic ecosystems, and animals located near trails. Regulatory instruments of cyclotourism in specially protected areas are analysed and compared in this thesis. This analysis has covered four European countries, the Czech Republic, Slovakia, Germany, and Austria. The lowest level of restrictions was found to be present in the Czech Republic, the highest on the other hand in Austria. The degradation of the environment caused by cyclotourism is examined in the practical section of this thesis. On cycling routes in 9 specially protected areas, segments were randomly selected for sensitivity assessment... Indicators of sensitivity were: presence of a water body, forest, tourist attraction, elevation change level, and geological subsoil. Segments with increased sensitivity were visited and evaluated. Out of total of 73 segments with increased sensitivity, degradation...

The use of passive samplers in the identification of antibiotics residues in treated waste water
Kostříková, Markéta ; Innemanová, Petra (advisor) ; Šťastný, Jan (referee)
With the increasing number of people on the planet, increases the consumption of antibiotics as well. A very big part of these antibiotics are transfered back into the environment in form of either their residues or metabolites. They usually negatively effect non-target organisms. Main sources of antibiotics are human and veterinary medicine, agriculture and animal production. The teoretical part of this thesis is devided into two chapters. In the first one the problematics of passive sampling, its usability and advantages compared to active sampling is discussed. These advantages are speed, low costs, no need for supply of outer energy and collection of samples in situ. Basic types of passive samplers that are intended for identification of foreign particles in the aquatic environment are described. Those described are Gore-Sorber, PDB, SPMD, POCIS, Chemcatcher, Ceramic Dosimeter, PISCES, MESCO a SLMD. The second chapter is about pharmaceuticals, more in depth about antibiotics in the environment such as Streptomycin, Amoxicilin, Ciprofloxacin, Lincomycin, Erythromycin, Spiramycin, Flumequin, Ofloxacin, Sulfamethoxazol, Chlortetracyklin, Oxytetracyklin, and methods of their detection. In the experimental part the possibility of combinig the advantages of passive sampling with the plate diffusion...
