Residua of Drugs in the Evironment - Interaction with Higher Plants
Jirák, Jaroslav ; Smrček, Stanislav (advisor) ; Moša, Marek (referee)
- 4 - Abstract The aim of this study was to carry out phytoextraction experiments using corn plants (Zea mays) and determine the phytoextraction efficiency for specific non-steroidal anti- inflammatory drugs and carbamazepine and their combinations. After 10 days of growth, a nutrient solution containing ibuprofene, naproxene, diclofenac and carbamazepine in concentrations ranging from 5 to 10 mg/L was added to hydrophonically cultivated plants. Nutrient solution samples were taken every 24 hours and the samples were then analysed using a HPLC/DAD system. At the end of the experiment, the experimental plants and roots were analysed for extractable residua using HPLC/DAD + FLD. The greatest phytoextraction efficiency was found for ibuprofene. The second and third most effective extraction was observed for naproxene and diclofenac, depending on the evaluation criteria. The lowest phytoextraction efficiency was observed for carbamazepine. With multi-component experiments, lower phytoextraction efficiency was found out for all substances with the exception of ibuprofene in combination with diclofenac and carbamazepine. The toxic impact of ibuprofene on plant transport mechanisms was also proven. The extractable residua analysis confirmed the ibuprofene's toxicity on plant transport mechanisms and also the...

Use of biomarkers for assessing environmental pollution by platinum group metals
Nedvědická, Lucie ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
This diploma thesis in the theoretical part analyses the characteristic feature of individual platinum group elements, their toxicity, anthropogenic sources and the presence of platinum group elements in the environment of the Czech Republic. In addition, there are specified types of bioindicators focusing mainly on lichens, mosses and needles. There are described individual bioindication techniques and pre-treatment of samples for platinum metals determination in bioindicators. The subject of the experimental part is to verify the sorption efficiency and ability of platinum and palladium using the SPE method and to determine the actual platinum metal contamination in selected localities in the city of Brno. There was also the additionally subject to verify the sorption potential of selected bioindicators and determination of the environmental pollution by platinum metals using the bag technique. In the experimental part, the bioindicators of moss Pleurozium schreberi, lichen Xanthoria parietina, lichen Flavoparmelia caperata and needles Pinus nigra were used.

Impact of air pollution on property values in Prague
Kaloč, Jiří ; Melichar, Jan (advisor) ; Kaprová, Kateřina (referee)
This thesis is aimed at the topic of economical evaluation of environmental goods, namely at estimating willingness to pay utilizing the hedonic price model. The theoretical part describes the impact air pollution has on the environment and human health. Methods of evaluation are also discussed with special attention on the hedonic approach. Goal of this thesis is to evaluate the impact of air pollution by applying the hedonic model to the real-estate market in Prague, thus giving the authorities a basis for their air pollution management.

Old environmental burdens
Augustová, Lucie ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
Tato práce se zabývá problematikou ekologických zátěží na území České republiky. Na příkladě konkrétní lokality analyzuji vývoj jednotkových nákladů vynaložených na odstranění nadměrného znečištění životního prostředí ve třetí etapě probíhajících sanančích prací. Dále hodnotím úspěšnost provedené sanace porovnáním litimních hodnot škodlivých látek v životním prostředí stanovených zadavatelem zakázky a výsledků, kterých dosáhla sanujcící firma.
