The Use of Asbestos, Remediation of Contaminated Areas and the Risk of Impact on the Human Organism
Štípek, Radek ; Bendl, Jiří (advisor) ; Mihaljevič, Martin (referee)
The work deals with the uses of asbestos minerals, methods of safe disposal of asbestos and the disease burden caused by exposure to asbestos fibers, of which the most dangerous is crocidolite. Attention is paid to the physical-chemical and structural properties, classification and explanation of the processes of their formation, indicating areas of the Czech Republic and abroad. Describes the history of asbestos use since ancient times to the 20th century, including mass balance asbestos consumed in the technosphere that over the past hundred years, amounts to almost 194 million tons. It then focuses on building fire protection, insulation and other products with different content of asbestos in the world which total over 3000 and registered on the characteristics of asbestos substitute materials, such as ceramic, glass and carbon fibers, aramids, wollastonite, vermiculite and perlite. Describes methods for determination of asbestos fibers in the air, water and soil as a complete course of rehabilitation of contaminated objects. Asbestos fibers pose a risk to human health in the form of asbestosis, first diagnosed in 1900, pleural hyalinosis, lung cancer and mesothelioma of the pleura, where the first evidence of association with exposure to asbestos dates back to 1955 and on the basis of which...

Construction project for implementation of Retirement home Žacléř
Bonaventura, Pavel ; Průcha, Aleš (referee) ; Kantová, Radka (advisor)
The aim of this diploma thesis is to prepare the construction of a Home for the Elderly in Žacléř. The work deals with technical regulations for the dismantling of asbestos roofing, demolition work and monolithic structures. For these regulations, a time plan for the implementation of monolithic structures, a control and test plan for monolithic structures, an itemized budget and a time and financial plan - object-oriented will be prepared. Furthermore, this work contains the coordination situation of the construction with broader transport relations, the design of the assembly machine, the report for the construction site equipment with drawings of the construction site equipment for individual technological regulations and last but not least the health and safety plan and assessment of construction noise. As part of the diploma thesis, several appendices were prepared for this stage, such as crane assessment, details of monolithic stair arms, noise wall scheme, budget for construction site equipment, environmental plan, ceiling and wall formwork scheme and staff balance for selected stages.

Studying the properties of fiber cement composites
Cederová, Kristýna ; Hoško, Marek (referee) ; Bodnárová, Lenka (advisor)
This diploma thesis deals with fiber-cement composites. Input materials are investigated for the production of fiber cement, are examined, the production and parameters of the pulp were monitored. Further, Hatschek's production technology and requirements for corrugated fiber-cement roofing are described. In the practical part the individual input materials and parameters of ground pulp were verified. The problem with production of samples and difference in the fineness of pulp milling in fiber cement products has been solved.

Rating solve the problem of asbestos in school of the region from the perspective of teachers
ŠMERHOVÁ, Ilona
Asbestos, a fibrous mineral with excellent chemical and physical properties and a very wide application, especially in civil engineering, is now known to be a proven human carcinogen and therefore its utilization was forbidden. It causes asbestosis, pleural hyalinosis, acute exudative pleuritis, lung cancer and pleural mesothelioma. Recently, many reconstructions of school facilities took place and are still taking place across the Czech Republic. This causes the drilling and cutting of asbestos and thus the release of fibres into the atmosphere and the interiors of buildings. Many reconstructions were also executed in South Bohemia, where panels containing asbestos were handled. This was a cause of concern not only for teachers, the employees of the schools affected, but also for the parents of children attending schools containing asbestos materials. A whole number of bodies in mutual cooperation participated in the disposal of asbestos in schools in the Czech Republic. It is thus very necessary and useful for public health officers and the above-listed entities involved, to have information about how their approach to the given problem and the whole solution of the problem was assessed by the teachers. The thesis consists of two parts: theoretical and investigative. The work deals with the evaluation of the solution to the problem of asbestos by authorities involved in the school from the teachers' point of view. The theoretical part deals with selected chemical pollutants in the work environment. It also focuses on the pollutant asbestos in general. Lastly, another chapter is devoted to the issue of the assessment of health risks, which is very closely related to pollutants in the work environment. The practical part contains the results that emerged from interviews with teachers. In the discussion, the results are compared with online articles and specialist literature. The necessary data for the research part of the thesis was obtained through qualitative research interviews with educators from the elementary school Máj I. Through the evaluation of the interviews, I answered the research questions and identified several hypotheses that could be tested in future quantitative research. In this thesis, I aimed to identify the level of cooperation of stakeholders in addressing the issue of asbestos disposal in the school concerned in the South Bohemian Region. Research suggests that the solution to the problem of asbestos in the school was judged largely positively by the teachers. They particularly praised the approach of the Municipality of České Budějovice. They criticized the errors made by the OHL ŽS and Mapoz Zliv companies regarding the reconstruction and also the company Sita cz, which carried out the sanitation works, after whose intervention the teachers lacked many things. Educators confused the competences of the regional health authorities with the competences of the Health Institute, and therefore the general public should get acquainted with the competences of these bodies in order to facilitate the communication between the different entities and the public, not only in the asbestos issue.
