Ecology in lighting
Špidlík, Jan ; Štěpánek, Jaroslav (referee) ; Krbal, Michal (advisor)
This bachelor’s thesis is focused on introduction to ecology in lighting technology. There are briefly described individual light sources and chemical substance used in the manufacture of components. For clarity is amount of toxic mercury in each light source displayed in well-arranged picture. Thesis is also focused on the influence of lighting technology in the environment and impact on the ecosystem. Closer look is made upon influence of mercury on environment and human life and also overall influence of mining metals and its devastating consequences for ecosystem. This work also deals with post processing of light sources by collective systems.

Arsenic and arsenic species cycle in environment
Ševčíková, Kateřina ; Sommer, Lumír (referee) ; Dočekalová, Hana (advisor)
This bachelor thesis, based mostly on literature retrieval, deals with monitoring of individual arsenic compounds in the environment and is also reviewing methods used for their analysis. The experimental part is focused on determination of various arsenic in the Oncorhynchus mykiss tissue by HPLC-UV-HG-AFS. Obtained results showed that the arsenic was present in the tissue of the Oncorhynchus mykiss in form of arsenobetaine, which is common for fishes and other aquatic animals and is not toxic even for consuments.

Determination of palladium by ET-AAS after previous preconcentration by solid phase extraction
Hajdová, Jana ; Čelechovská, Olga (referee) ; Komendová, Renata (advisor)
The theoretical part of this master’s thesis focuses on the characteristic of Palladium, his uses in the automotive convertors, the occurrence in the environment, bioaccumulation and human health risks. Next there are described the basics of biomonitoring and summarize suitable biomonitoring method for capturing airborne dust. There are also evaluated appropriate methods for preconcentration and determination of Palladium. The aim of experimental part of this thesis is description and evaluation optimalization preconcentration method SPE by using sorbents silicagel C18 and QuadraSil TA. Optimization of method conditions of electrothermal atomic absorption spectrometry (ET – AAS). The determination of Palladium using optimal conditions follows in real samples in the form of exposure lichen (Hypogymnia physodes) by automobile traffic in Brno.

Photovoltaics in architecture
Bidlová, Jitka ; Kyselka, Mojmír (referee) ; Budkeová, Branislava (referee) ; Chybík, Josef (referee) ; Urbášková, Hana (advisor)
Nowadays there are more and more installations of renewable sources of energy. One of them is changing of sunlight into electric energy by using photovoltaic cells. Installation of photovoltaic systems into buildings and landscape is becoming modern approach to architecture and urbanism. It creates new architectonic expression - "solar design" and brings not only the energy profit but successful substitution for traditional materials and its usable properties.

Evaluation of ecotoxicity of selected pharmaceuticals
Weiss, Jan ; Dvořáková, Dagmar (referee) ; Zlámalová Gargošová, Helena (advisor)
In recent years consumption of drugs and thus the quantity of their residues in natural ecosystems is increasing. It is necessary to deal with their possible negative effects on the environment. This thesis is focused on the ecotoxicological evaluation of pharmaceuticals. Diclofenac and ibuprofen from the group of non-steroidal anti-inflammatory substances, penicillin G and ampicillin from the group of antibiotics were tested. Mainly tests on aquatic organisms were used to evaluate of ecotoxicity, because the tested pharmaceuticals are predominantly occurred in the aquatic environment. Daphnia magna, Thamnocephalus platyurus, Artemia salina, Sinapis alba, Lemna minor, and Brachionus calyciflorus were used as testing organisms. Values of LC50, EC50 and IC50 were determinated and the ecotoxicity of pharmaceuticals was compared.

Analysis of Environmental Taxes in the EU
Hrdličková, Lenka ; Marčišák, Petr (referee) ; Kopřiva, Jan (advisor)
The subject of the thesis „Analysis of Environmental Taxes in the EU“ is describe and evaluate the implementation of the ecological tax reform in the European Union, especially in the Czech Republic. The work is dividend into four parts. The first part is devoted to the theoretical basis of the work, that is a brief introduction to the issue of taxes and the environment. The second part is concerned with the introduction of environmental taxes in both the EU and Czech Republic. The third part is devoted to comparison of taxes that are applied in the Czech Republic with the EU countries. The fourth part will deal with the impact of the reform on the particular business entity and household.

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.
