Influence of advanced oxidative processess on ecotoxicity of pesticides
Goma, Bernadette ; Procházková, Petra (referee) ; Zlámalová Gargošová, Helena (advisor)
The topic of this bachelor thesis is a study of the influence of advanced oxidation processes on the ecotoxicity of pesticides Metazachlor and Chloridazon. Both herbicides are commonly used to protect crops such as oilseed rape, turnips, chard or fodder beet against whole range of undesirable monocotyledonous and dicotyledonous plants. Application is most often on large areas and therefore pose a high risk to the quality of the environment. The possible influence on the representatives of producers and consumers of the aquatic ecosystem was monitored in the work. Solutions of pesticides, which were subjected to selected methods of treatment using advanced oxidation processes, were tested on aquatic organisms, specifically on crustaceans Daphnia magna and aquatic plant Lemna minor. From the results of individual tests, the ecotoxicological values of EC50 and IC50 were calculated and their ecotoxicity and thus the efficiency of oxidation processes in the removal of pollutants from wastewater were compared.

Assessment of the effectiveness of advanced oxidation processes via ecotoxicity tests
Procházková, Petra ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
Recently, an increasing problem in wastewater treatment is the insufficient removal of organic pollutants. These substances can be toxic to the environment already in a small amount, either acutely or chronically. The goal is therefore to develop of technologies that ensure their effective removal. One possibility is to use advanced oxidation processes. Advanced oxidation processes work on the principle of non-selective oxidation mediated by OH radicals. Several methods such as O3/H2O2 (Peroxone), UV/H2O2 or Fenton´s reaction can be used to generate them. The aim of this thesis was to evaluate the effectiveness of the used advanced oxidation processes in wastewater treatment via ekotoxicity tests. Wastewater samples treated with advanced oxidation processes on the pilot unit showed low values of acute toxicity for selected test organisms (D. magna, T. platyurus, S. alba, L. minor). For the sample of waste water that was treated with the UV/H2O2 on AOP laboratory unit, there was an increase in acute toxicity on the testing organism D. magna and L. minor. The similar effect was observer in the tests with the D. magna with the model samples treated with the same method, while the tests on the L. minor showed a reduction in toxicity.

17th Meeting of the National Commission for Services of the Slovak Republic
Procházková, Petra ; Chodounská, Alena
Národná komisia pre služby (dále jen NKS) je poradním orgánem ředitelky Slovenské národní knihovny. Cílem NKS je rozvoj knihovnicko - informačních služeb a navázání mezinárodní spolupráce. Členy komise se stali nejen zástupci Národní knihovny ČR, ale od roku 2009 také zástupci NTK. Komise zasedá alespoň jednou ročně a zabývá se předem stanovenými otázkami. Náměty, které vznikají z její činnosti jsou předkládány ředitelce Slovenské národní knihovny a ředitelům ostatních knihoven zastoupených v komisi. XVII. zasedání proběhlo v Slovenskej pedagogickej knižnici v Bratislave. Zástupci NTK v komisi aktivně participují, vyjadřují se k probíraným tématům a přináší příspěvky shrnující zkušenosti z oblasti služeb NTK. Letošní zasedání bylo zaměřeno na prezentaci projektů digitalizace v SNK, knihovní služby, EIZ a aktuální problémy knihoven. Účast zástupců Národní technické knihovny na Národní komisi pro služby SR má velký význam nejen pro výměnu zkušeností a vzájemnou inspiraci, ale také pro navazování kontaktů a vzájemné spolupráci.
