The impact of the nuclear accident at Chernobyl on the environment
Dvořáková, Markéta ; Braniš, Martin (referee) ; Přibil, Rudolf (advisor)
Modern civilization is dependent on the production of energy. But there are only two energy sources that can cover our energy needs: the energy produced by burning fossil fuels and the energy produced by nuclear fission. People are afraid of nuclear accidents and storage of radioactive waste in relation with the use of nuclear energy. My work focuses on the risk of a nuclear accident, which is demonstrated on the Chernobyl nuclear accident. There were obsolete types of nuclear reactors at Chernobyl. The staff, which serviced the power plant, was inadequately prepared for the experiment. A lot of radionuclides released into atmosphere after the explosion at Chernobyl. They affected mainly the near area from the power plant. There was announced the thirty kilometers large Zone of Alienation. My work deals with the consequences of the accident at Chernobyl for environment - health effects for people and the exposure to animals and plants in the near but also in farther area from the Chernobyl nuclear power plant.

Tesař, Tomáš ; Braniš, Martin (referee) ; Hůnová, Iva (advisor)
The aim of this paper is to summarize harmful effects of tobacco smoke on human health, using recent studies of international significance level. It also brings the potential risks which may ETS cause, particularly cardiovascular disease and the effects of passive smoking, but many other diseases associated with indoor pollution caused by tobacco smoke. This work also deals with the chemical and physical composition, indicating the pollutant, the differences of the individual components and the methods by which the smoke exposure is investigated. The aim is to present the frequently discussed issues related to indoor environment and human health, as well as air pollution indoors. Finally, the thesis will outline economic damage and describe the situation and legal standards associated with passive smoking in the Czech Republic.
