Hazardous Chemical Substances and Preparations
Lacina, Petr ; Adamec, Vladimír (referee) ; Mika, Otakar Jiří (advisor)
The aim of this bachelor‘s thesis is to present a brief and current summary of hazardous chemical substances based on simultaneous laws in force. It introduces basic information and data on industrial hazardous chemical substances and basic characteristics of chemical warfare agents. This thesis also deals with documentation related to solutions for emergency events in connection with hazardous chemical agent escape – type plans, methodical sheets. The work results in a proposal for another methodical sheet focused on interventions of concrete hazardous chemical substance escape, i.e. hydrogen chloride. In this way the proposal can extend the methodical sheets for chlorine and ammonia currently in use. This thesis also presents list of toxic chemical, industrial and warfare substances for working up another methodical sheets.

Possible Misuse of Hazardous Chemical Industrial Toxic Substances
Gregorová, Renáta ; Dana, Čípková (referee) ; Mika, Otakar Jiří (advisor)
Bachelor thesis, „Possible misuse of hazardous chemical industrial toxic substances“, deals in the first part with legislation, which dictates conditions for handling with hazardous toxic substances. In the next part work covers with terrorism and chemical substances abusement in context with terrorism. Security of selected buildings and transport is also solved. The main aim of this work is to make a list of hazardous toxic industrial chemicals which are made in the industry of Czech republic and therefore can be abused easily. At the end of the work is the set of effective limitation of the potential abuse of dangerous toxic industrial substances provided and the guide how to behave in case of terrostist attack in the subway is designed.

Natural toxins in food and their effect on human health
Houdková, Kristine ; Bušová, Milena (advisor) ; Schlenker, Anna (referee)
This bachelor thesis deals with the occurrence of natural toxic substances in food and describes their effect on human health. It focuses on toxic substances that are a natural part of plants, animals, and also on natural contaminants. This work is divided into theoretical and practical part. The aim of this work is to provide information and raise awareness about these substances, because they are an integral part of most foods. The purpose of the practical part is find out the level of public awareness of toxins in food and discover the frequency of mycotoxins appearences in food from the Rapid Alert System for Food and Feed (RASFF), which operates within the European Union. Mold toxins are a major worldwide problem, both in terms of public health and global economic. The research part of the work was carried out using a questionnaire survey through social networks. The general public seems to have a basic awareness of food safety and toxins substances in food. The bachelor thesis can serve as an informative and educational material for the public. Key words natural toxins - toxic substances - mycotoxins - alkaloids - poison

Toxic substances in food and their effects to human health
KADLECOVÁ, Hana
The bachelor thesis "Toxic substances and their effects to human health" deals with characteristics of selected historical periods of toxicology. It describes the basic concepts of toxicology. It briefly characterizes toxic substances of plant and animal origin. More attention is paid to mycotoxins, especially aflatoxins, fumonisins, ochratoxins and zearaleon. A very important part of this thesis is the prevention of the effects of toxic substances on human health and describes the partial measures that are necessary before consumption or preparing of food. The practical part examines the awareness of university students about important toxic substances in food. It assesses whether these students recognize the desired mold species on food. Next it is interested in what precautionary measures are taken by university students before consuming and preparing food. The conclusion of the thesis shows that the know-how of university students is relatively high.

Devices and equipment for detection of toxic substances used in the Army of the Czech republic.
STARŠÍ, David
The aim of this bachelor work is primarily evaluate the preparation of chemical observers and members of cooperatives radiation and chemical reconnaissance, in the detection of toxic substances and their possible use in cooperation with the Integrated Rescue System. In the theoretical part is mainly described techniques and devices, which have military units, a brief explanation of the Central Emergency Plan and the Chief's of the General Staff regulation, which represent the obligations of the Army of the Czech Republic to the strengthening of the integrated rescue system in case of emergency. The first part of the research question aims to determine how is carried out the training of the chemical of observers and members of cooperatives radiation and chemical reconnaissance, whether the training is done according to applicable standards, is sufficient and the most widely used technique and equipment used by the military. Furthermore, whether it would be appropriate to increase the number of chemical observers and members of cooperatives radiation and chemical reconnaissance, or by increasing hours of theoretical and practical training led to greater readiness chemical team members. It is important to note that the function of the chemical observer is not the primary systemized occupation which the professional soldiere held, but the function is affiliated functions to systemized occupation. The second part of the research question focuses on the readiness of chemical teams of individual units on strengthening and coordinate activities together with the Integrated Rescue System, their possible use, and whether carried out coordinated training between these components. Within the objectivity were approached members of both air forces and ground forces. The planned output of this thesis was to processing of data of the readiness of radiation and chemical reconnaissance teams to strengthen the Integrated Rescue System within the detection of toxic substances and determine whether soldiers are a sufficiently trained for the strengthening of the Integrated Rescue System within the detection of toxic substances.

Toxic substances in combustion gases of waste engine oils from evaporating boiler 29 kW
Tydlitát, Vratislav ; Pekárek, Vladimír
Information about measured contents of toxic substances in gases from combustion of two fuels (waste engine oil and waste hydraulic oil) in evaporating boiler Kroll W401 VL 29 kW is presented. The content of halogens and of toxic metals is under official limits. Total toxicities of PCDD/Fs 0,117 and 0,040 ngTEQ.m-3 respectively were found; total toxicities of PCBs 0,004 and 0,0017 ngTEQ.m-3 respectively were found. The contents of 10,5 and 7,9 ?g.m-3 of polycyclic aromatic hydrocarbons respectively were found. Large part of toxic metals remains in the solid rest (ash and carbon) of combustion.
