System approach to assessing the extent of environmental damages in terms of the risk engineering
Schüllerová, Barbora ; Adamec, Vladimír ; Tragan, Tomáš
Road accidents have resulted not only in loss of human life, health and material damage, but also in the environmental damages caused by leaks of operating fluids or transported hazardous substances. Determining the severity and extent of the occurred accident is based on the expertise of experts. Besides the common methods, the risk engineering methods can be applied while resolving this issue. The contribution introduces the possibilities of using selected methods of risk analysis, which are the core of risk engineering, as a support tool for determining the extent of the damage incurred on the environmental components, including recommended procedures, combinations and applications of these methods.

Presence of heavy metals in vicinity of the roads in Brno
Brzobohatý, Jan ; Adamec, Vladimír (referee) ; Doležalová Weissmannová, Helena (advisor)
Diploma thesis deals with the risk assessment of metals in soils near roads in the city of Brno. For samples collection has been chosen twenty-five localities which were divided into five groups depending on the traffic load, in order to compare the impact of transport on the risk of soil contamination with metals. In the soil samples were determined levels of six hazardous metals (Cd, Hg, Pb, Zn, Ni, Cu). Lead, zinc, nickel and copper were determined by the flame atomic absorption spectrometry (F-AAS), cadmium by the electrotermic atomic absorption spectrometry (ET-AAS) and mercury by the advanced mercury analyzer AMA 254.

Assessment of soils and sediments contamination by heavy metals in the region Jihlava river
Marek, Milan ; Adamec, Vladimír (referee) ; Doležalová Weissmannová, Helena (advisor)
This diploma thesis deals with a potential contamination of hazardous metals of soil and sediments. The metals cadmium, copper, lead and mercury were chosen, their specification, limited concentration and methods of determination are also described in thesis. City Jihlava and its surroundings were chosen for evaluating pollution of the soil and sediments in this area. In collected samples of the soil and sediments presence of copper, cadmium, lead and mercury were detected via atomic absorption spectrometry (F-AAS, ET-AAS, AMA 254). The metal pollution of soils and sediments by hazardous elements in Jihlava River and in Jihlava region was evaluated.

Heavy metals contamination of selected Brno city localities
Debnárová, Andrea ; Adamec, Vladimír (referee) ; Doležalová Weissmannová, Helena (advisor)
This thesis is focused on the degree of soil contamination with heavy metals in urban area of Brno. Samples were collected in three periods from October 2009 to March 2010, to represent different seasons and their impact on the concentration of heavy metals in examined soil. Ten locations was chosen, each with different level of concentration, starting with busy traffic area where the concentration of means was high continuing to areas located around habitation or parks. As result four elements were determined in every sample: Cu, Cd, Hg and Pb. Presence of copper and lead were detected by flame atomic absortion spectroscopy (F-AAS) and, cadmium by the help of electrothermal atomic absortion spectroscopy (ET-AAS). For the determination of mercury was used advanced mercury analyzer (AMA).

Safety and Protection of Health during the Work of Professional Drivers
Chodurová, Zuzana ; Novák, Jaromír (referee) ; Adamec, Vladimír (advisor)
The theme of this bachelor thesis is Safety and Protection of Health during the Work of Professional Drivers. Given that most accidents at work in the Czech republic is in connection with vehicles, it is not surprising that safety and health at work is now becoming a priority for many employers. The aim thesis was to assess the risks arising from work performed by professional drivers and to suggest security measures to protect their health. The theoretical part explains the basic concepts and laws relating to the profession of professional drivers, a general description of the factors affecting the work environment and health and practicable methods for determining risks. The practical part of the work is focused on transport company called H.A.S. Ltd. The method of "what if analysis" is processed by the risk assessment and prevention and in cooperation with station regional hygiene is set categorization work. Part of thesis is questionnaire survey and recommendations for drivers, which are intended to minimize damage to health.
