Assessment of contamination around the landfill Pozďátky
Sedláček, Jaroslav ; Zlámalová Gargošová, Helena (referee) ; Doležalová Weissmannová, Helena (advisor)
This bachelor thesis is focused on the characterization of the locality and on the evaluation of water contamination in a short distance from Pozďátky - the hazardous landfill. The occurrence of the selected contaminants is assessed. The samples were collected at five different locations: landfill leaks, the confluence of these leaks with the Prašinec creek, in other parts of the Prašinec creek affected by contaminated waters and on the very site of the creek Prašinec where no water pollution has been expected.
Option usage new technology at activation waters in Zoo Brno
Kašpárková, Petra ; Zlámalová Gargošová, Helena (referee) ; Kotlík, Josef (advisor)
This bachelor´s thesis analyses contemporary condition of water-provision in ZOO Brno with emphasis on environmental defensibility of local fauna and flora. The theoretic part surveys networks of single water mains and reviews utility of particular water pipes. Operational problems of water-supply are specified further. The experimental part closely concerns the water system in tanks of Tropical Kingdom exhibition by monitoring water qulity, the effect of water composition on bred species and water circulation.
Application of alternative ecotoxicity tests for evaulation of contaminated environmental matrices
Doležalová, Šárka ; Doležalová Weissmannová, Helena (referee) ; Zlámalová Gargošová, Helena (advisor)
This bachelor thesis deals with assessment of harmful effects of contaminated matrices on biota of nature ecosystems via alternative ecotoxicology tests. The alternative and standard ecotoxicology tests are summarised and compared in the thesis. Furthermore, the need of broadening of basic test battery required by actual Czech legislation is discussed. The basic test battery should be widened by the tests on decomposer trophic level for solid and liquid matrices and by contact tests for solid matrices. In connection with that the test batteries for evaluation of environmental matrices ecotoxicity are proposed.
Importance and impact of phthalates during peritoneal dialysis and current possibilities of their replacement
Nohelová, Gabriela ; Zlámalová Gargošová, Helena (referee) ; Čáslavský, Josef (advisor)
This thesis deals with the importance and influence of phthalates in peritoneal dialysis (PD) and the current possibilities of their replacement. The information about phthalates – esters of phthalic acid - was completed with focus on the most commonly used plasticizer in medical material, bis(2-ethylhexyl) phthalate (DEHP) and its effects on the human organism and the environment. The possibilities of substitution of PVC in peritoneal dialysis were searched and their advantages and disadvantages were evaluated. As the evidence of phthalates absorbed by the human body in carrying out peritoneal dialysis selected studies performed in Germany and in our country, dealing with this issue, were used. High performance liquid chromatography (HPLC) with UV detection at 224 nm or gas chromatography - mass spectrometry (GC / MS) was used here for the determination of phthalates in the blood and dialysate in peritoneal dialysis. Extraction of sample with the suitable solvent and purification of the extract predates the actual analytical determination of sample.
Verification of the commercial culture medium quality for food microbial analysis
Peterek, Miroslav ; Zlámalová Gargošová, Helena (referee) ; Omelková, Jiřina (advisor)
This thesis describes verification of the commercial culture medium quality for food microbial analysis. This thesis deals with morphological, cytological and physiological properties of Leuconostoc mesenteroides subsp. dextranicum. In experimental part of this thesis are described methods suitable for classification of this microorganizm in production use.
State Veterinary Administration as an Element of Integrated Emergency System
Šudáková, Michaela ; Zlámalová Gargošová, Helena (referee) ; Kučínský,, Petr (advisor)
Theme of my bachelor’s thesis is The State veterinary administration as an element of the Integrated Emergency System to solve extraordinary events. For the draw up of my bachelor’s thesis I drew from the domestic and foreign sources. At the first part I deals by legislation and cooperation of The State veterinary administration with elements of the Integrated Emergency system. Then I focus on activities of the veterinary administration in the event of liquidation of dangerous diseases and other extraordinary events. At the conclusion of the thesis I drew own proposition of brochure The Decalogue of bird flu for public.
Importance of contact tests of ecotoxicity
Modlitbová, Pavlína ; Doležalová Weissmannová, Helena (referee) ; Zlámalová Gargošová, Helena (advisor)
This bachelor thesis is dealing with an issue of contact tests of ecotoxicity and their importance for solid matrices testing as wastes, contaminated soil etc. According to the requierements of current legislative, ecotoxicity of these materials is evaluated only for results obtained with testing their water leach. Need of insertion ecotoxicity contact tests into mandatory set of tests is discussed in thesis, because current set of tests is relevant only for water ecosystem and does not support sufficient prediction for eventual ecotoxicologic impacts for terrestrial ecosystem.
Ecotoxicity of substances with hormonal effect
Cvikýřová, Zuzana ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
This bachelor thesis deals with the fate and ecotoxicity of chosen substances with hormonal effect in the environment. This group of compounds covers steroid hormones, which are produced for these effects, but also a lot of xenobiotics, showing similar activity. The substances disrupt the endocrine system by various mechanisms. They can cause feminization, masculinization, disruption of reproduction, etc. In terms of chemical structure they belong to the group of phthalates, polychlorinated biphenyls, pesticides, heavy metals and others. The impact of these substances, especially on the aquatic ecosystem, which becomes their reservoir in most cases, was assessed.
The importance of algal tests for ecotoxicological evaluation
Chovanec, Petr ; Zlámalová Gargošová, Helena (referee) ; Doležalová Weissmannová, Helena (advisor)
This bachelor thesis is aimed at the study of algal tests. Within the frame of this thesis I have performed a literature research into findings about all possibilities algal tests in ecotoxicity. This work is engaged in short description green algae, as a testing organisms and their usage for ecotoxicological evaluation.
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.
