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...

Subsidy Support of the Sustainable Waste Management
BEDNÁŘOVÁ, Renata
The subject of the dissertation is the issue of the waste management with special emphasis on the recycling of the construction and demolition waste. The recourse is an analysis of the key instruments regulating the activities and behaviour of market operators in this field toward fulfilling all-society priorities and principles of the sustainable development, where special accent is put on the area of subsidy policies and programmes. The aim of the dissertation is to analyse and evaluate the setting of the selected subsidy programme in terms of economic and ecological efficiency with the emphasis on the assessment of the impact on the recipient. The subject of the research will be a priority axis 4 "Improvement of Waste Management and Removal of Old Environmental Burdens" within the Operational Programme Environment 2007 - 2013. In the literature review basic concepts and important definitions are defined, followed by the comprehensive and complex searches of the problematics from different angles of view. First of all, the global aspect of environmental protection is discussed, broader historical, legal, economic and political contexts, that are essential fundament for understanding the current and future challenges both globally regionally, are summarized. Hereafter, a more detailed description of the situation of the European Union is followed, then the overview is completed by a detailed view at the state of the problematics in the Czech Republic. Subsequent chapters are devoted to a detailed analysis of the waste management sector, again in terms of global, European and national standpoint, in the end the view is focused on the key issue of the dissertation problematics of construction and demolition waste. In the application part the fulfilling of the stated objective of the dissertation through four defined hypothesis is solved. Hypotheses verify the efficiency and appropriateness of the setting of the system of subsidies in the frame of the monitored programme. The emphasis is imposed on the assessment of the impact of the allocated subsidies to the private entities on their economic and environmental efficiency.

Recycling of the construction waste
NOVÁČKOVÁ, Pavlína
The growth of waste is a phenomenon which is typical for the economically developed society and concurrently one of major problem with environmental protection. Therefore it is necessary legislatively regulate the increasing volume of waste, support waste recycling and support consequent use to keep the sustainable development. Construction and demolition waste presents a significant part of the total volume of waste. Recycling of construction and demolition waste has two basic advantages. On the one hand, it significantly reduces the capacity of waste repositories, and on the other hand recycled material is an important source of reusable materials.
