Monitoring the effect of lead pipes on drinking water quality for consumers
Vostrčilová, Markéta ; Talašová, Lucie (referee) ; Biela, Renata (advisor)
The thesis is divided into several parts. At first, there are written information from the laws and decrees concerning the lead pipeline, drinking water, observance of lead concentrations in drinking water, etc. Then the water connection, the ownership relations to the connection and the materials used for the water connection are defined. The next chapter deals with lead, lead pipeline, lead in drinking water and the legislative requirements for lead content in drinking water. Other part is about the health risks of lead in drinking water. These theoretical parts follow the practical part, which focuses on drinking water quality testing, which was in contact with the lead pipeline. This section describes drinking water sampling principles for determining the concentration of lead, the locations where the samples were taken, the methods used to determine the concentration, the description, the results and the evaluation of the information. The last chapter shows the methods and materials that remove lead from water.

Possibilities of removing lead and other harmful elements from waste from metallurgical processes
Jedličková, Veronika ; Kurka, Vladislav (referee) ; Čamek, Libor (advisor)
The work describes an overview of individual variants of processing and recycling of metallurgical waste. From the economic and especially ecological point of view, the possibility of landfilling this waste seems to be very unsatisfactory. Currently a considerable amount of material from previous production is stored in landfills. The presence of hazardous elements in this waste means a certain risk to the environment. Undesirable elements include Zn, Pb, Cd and others. In these experiments, changes in the chemical composition of blast furnace sludge were observed with a focus on changing the concentration of lead and zinc in the form of oxides. The sludge was heated in a rotary kiln to different temperatures and under different atmospheres. Lead oxide has been shown to be effectively removed in oxidizing atmosphere, while zinc oxide concentration is effectively reduced in reducing atmosphere.
