Preparedness of the selected area to participate in implementation of the tasks of civil protection during the release of hazardous chemicals.
ŠEVČÍK, Martin
This diploma thesis and its research deals with the preparedness of the population, pedagogues and representatives of municipal council, to participate in tasks of population protection during the leak of dangerous chemical substances. The work develops research from my Bachelor thesis from 2017, where was my task to verify preparedness of the integrated rescue system to deal with the leak of dangerous chemical substances. The aim of this diploma thesis was to find out, if is the selected area able to adequately respond to hazards arising from the leak of hazardous chemical substances. In order to assess preparedness, slightly different questionnaires were used, those questionnaires were answered by the residents of České Budějovice, teachers working at secondary schools in České Budějovice and representatives of the city and representatives of the South Bohemian Region. The results of the questionnaire survey are presented using descriptive statistics, interesting results are shown using graphs. A high degree of unpreparedness of respondents was found. According to the results of the questionnaire survey, some respondents may also behave dangerously in the events of leakage of hazardous chemicals. The contribution of this work should be increasing and improving awareness in this area. To this purpose, was created an information leaflet containing lot of important information, which was distributed to the population. The benefit which this work has already brought, is to alert representatives from city and region councils, as well as teaching staff, to improve their knowledge of hazardous substances. According to the feedback of several representatives, analyzes focusing the transport of dangerous substances can be expected in the near future. This work can be used as well as a source of information and can be used to compare it with other researches.

Potahové usně používané pro výrobu čalouněného nábytku, jako zdroj emisí těkavých organických látek (VOCs)
Kotoučková, Barbora
The estimated thesis adresses the issie of uphostery leathers, used for the manufacture of uphostered furniture, as a possible source of emissions of Voltare Organic Compounds (VOCs). In the next section is describted the methology for measuring emissions of VOCs, which emit form natural leather, used devices and equipment. The tables show the individual measurements and their evaluation, including a comparison of the potencial impacts of the technological operations of manufacturing the natural leather. An integral part of the of the thesis is to analyze the impact of individual technological operations in the production on the quality of the resulting leather. In the final part of the thesis describes and evalues the impact of natural leather in the quantitative and qualitative composition of the emissions of selected types of natural leather, including the interpretation of the results and their potential benefit for practice.

Illegal storage of chemicals and hazardous waste as a source of possible accidents
HRON, Pavel
This thesis presents a comprehensive view on the issue of illegal storage of hazardous substances and waste in the Czech Republic. The work is highly relevant, by the fact that illegal warehouses, or buildings where there is unlawful storage, the Czech Republic can find countless and their discovery is only a matter of time. In the theoretical part of the thesis deals with the legal definition of waste management, the topic of chemical substances and mixtures and their development at international and national level, so as to issues concerning these areas seen over the years. We describe the specific laws that serve as the theoretical basis for understanding the definition of waste and themes chemicals or mixtures. Another part is a statistical look at the amount of waste produced in the Czech Republic, the Czech Republic 's production with other countries of the European Union and the historical perspective. Results section is largely concerned with the detailed analysis of cases that the issues of illegal storage in the Czech Republic opened, that is, cases of illegal storage communities Libcany, Chvaletice and Nalžovice. Interestingly a certain comparison was analyzed other events associated with such dealings, and in 2010 in the village of Bela nad Svitavou . This case was very specific and publicized in the media, with regard to the fact that the property owner had a mental disorder. There is also outlined what motives leading operators of these stores for their operation. Great time and especially financial cost of illegal disposal of stores is devoted to the next chapter. In connection with this chapter builds on the measures taken immediately for further such objects as identifying and initiating a control action called " brownfields". Part of the work dealing with the simulation of a potential hazard in the event that occurred some of these accident scenarios is very alarming. Terex program to simulate leakage of hydrogen cyanide in a specific amount, which was formed by the reaction of potassium cyanide and inorganic acids. Given that the placement of substances in the warehouse disregarded, and the material rather than with expertise stored with the need to save the maximum space, this reaction actually could occur. Simulated the escape of a former factory in the village Vertex Libcany. Indeed, the alarming fact is that at a distance of one hundred meters from the house was situated kindergarten and elementary school, where the daily ranges to three hundred people. In conclusion the author's position is defined and assessment solutions to the operators concerned in the event of liquidation of illegal warehouse Libčany a definition of the fundamental weaknesses associated with the solution in these cases. Further proposals are discussed, especially legislative, methodological and organizational aspects that must be incorporated into the legislation of our country, so that in the future establishment of such a warehouse avoided. The final section describes the recommended procedures for what to do in the event of a chemical accident.
