Pollutants in laboratory waste waters
Červenka, Jiří ; Zmrzlý, Martin (referee) ; Sponar, Jan (advisor)
Mercury is a very consequential pollutant. It´s contained in all components of environment. Analysis of mercury is very demanding. Since mercury is ranked among dangerous chemicals, its quantity is limited and checked not only in environment. The aim of this thesis was to determine concentration of mercury in water from labs and in influent and effluent water from neutralization station of Brno university of Technology, Faculty of Chemistry. Water from neutralization is also mixed with sewage. Advanced mercury spectrometer AMA 254 was used or analysis. Results confirmed, that water flows out from lab to neutralization with relatively high concentration of mercury, highly exceeding limits of drainline. Water from neutralizing station also doesn´t show so high concentration of mercury, because it is mixed with waters from other labs and pH of water is amended. Special waste bottles for liquid waste with risk elements and dangerous compounds are available; from results can be decided, that not everybody follows the rules and some people might pour the waste right in to the sink. Resolution could have been safer acquisitions in labs. Students, who manipulate with dangerous chemicals should be alive to risk, which threatens with pouring into the sink, contamination and dangerous for all components of environment.

Pollution control strategies and techniques for combustion processes
Kunc, Vlastimil ; Chlápek, Petr (referee) ; Bělohradský, Petr (advisor)
Bachelor’s thesis deals with the problems of combustion process. The work gives the overview and the description of individual design parameters of the combustion facility. The analysis of the influence of design parameters on emissions formation is followed by the description of individual kinds of emissions and their impact on the environment. Next the most used reduction techniques are described. The work is closed by the overview of the emission limits in the Czech Republic.

Quality and Environment management system
Stoy, Tomáš ; Musil, Martin (referee) ; Fiala, Alois (advisor)
This paper deals with interaction of quality and environment and their influence. The first part describes the quality itself and tries to explain how it works and how we can reach the quality. The focus of this description is on the Quality Management System. The second part of this paper deals with ecology and environment and focuses on the production and considers environment when trying to reach high quality of products.

Training center Hustopece - gross substructure
Polenský, Jaroslav ; Rotrekl, Ivo (referee) ; Biely, Boris (advisor)
The content of the bachelor’s thesis is a technological proyect of the training centre of the company of Teramex s.r.o. in Hustopeče. In my work I deal with a technological instrument of ground works and with foundations. In other parts the inspection test plans, the mechanical set and the equipment of the building site are described. Subsequently, the occupational safety, the progress chart and the budgetary composition of the construction are dealt. I also follow up the comparation of the various options of the road transport.

Chirality and its importance in environmental organic analysis
Svobodová, Dagmar ; Friedl, Zdeněk (referee) ; Čáslavský, Josef (advisor)
This bachelor thesis is elaborated as literature search focused on the characterization of chirality and its importance for the environment. This work also gives review of the analytical methods and procedures aplicable for the chiral analysis of the organic pollutants. Obtained information showed that the importance of the chirality in the environmental chemistry is great. Individual enantiomers exhibit different toxicity and biological activity in the environment and therefore their monitoring by chiral analytical methods is essential.

Question of new halogen containing compounds in environment
Roček, Richard ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
The target of my bachelor´s thesis is fabrication of literary recherche on theme brominated flame retardants. Into this group belong primarily polybrominated diphenyl ethers and compound hexabromocyclododecane. These compounds belong to perzistent organic polutants, whose production grew to the late time. Nowadays there are occur in almost all part sof environment. For their determination is using liquid and gas chromatography methods connected with mass spectrometry detection.

Question of perfluorinated compounds in environmental compartments
Šima, Aleš ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
The target of this bachelor work is processing of literature searche on the topic: Question of perfluorinated compounds in environmental compartments. The most important substances of the group of perfluorinated compounds are perfluorooctyl sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Perfluorinated compounds have special physical and chemical properties, which make them valuable for usage in different industrial branches. These properties, which make them so useful are also the reason, why they are so harmful for the environment. The perfluoroalkyl chain is not affected by photolysis, hydrolysis or biodegradation. PFOS and PFOA are very persistent in the environment. The presence of the PFOS have been detected in liver, blood, muscle, kidney or brain of many animal species including the invertebrates over fish, amphibians, birds, mammals up to human being all over the world. An alarming fact is, that the high concentrations of PFOS have been found in arctic animals tissues far away from anthropogenic sources. Improved analytical techniques enabled scientists to take interest in perfluorinated compounds in more detail, which led to the identification of quite a number of these compounds. Nowadays there is an endeavour to eliminate the application of perfluorinated chemicals and replace them gradually by other compounds, which are better degradable and do not affect the environment.

Possibilities of identification of flavonoids in environmental matrixes
Magdechová, Andrea ; Zlámalová Gargošová, Helena (referee) ; Vávrová, Milada (advisor)
Inherent part of plants are active substances; flavonoids belong to this group. They are used in medicine, cosmetics and they shloud be a part of our diet because of their positive effects. This bachelor thesis is focused on the identification of flavonoids in selected types of coniferous trees and moss. Pines, firs and spruces were selected as the representants of coniferous trees, together with mosses Polytrichum formosum and Rhytidiadelphus subpinnatus. Flavonoids were isolated using liquid-liquid extraction and identified using thin layer chromatography and high-performance liquid chromatography.

Wind power plant in area North Moravia
Pasírbková, Adéla ; Zmeškal, Oldřich (referee) ; Kotlík, Josef (advisor)
This thesis deals with analysis of wind parks from aspect of EIA, the annual capacity factor and the economy of operation. It shows the utilization of wind power in wind plants, wind potential of the Czech Republic and criteria for selection locations for construction wind plant. It describes the Act No. 100/2001 Coll., on environmental impact assessment, in which is the EIA process regulated. It analyses potential and real possibilities of wind power utilization in the North Moravian Region in connection with the Territorial Energy Policy.
