MIKSAI, Filip. Compound of nitrogen considering from their toxicity and flammability. [Bachelorthesis]. Technical University in Zvolen. Wood Faculty; Department of Chemistry and Chemical Technologies. Supervisor’s name: Ing. Eva Výbohová, PhD. Professional qualification level: Bachelor degree. Zvolen : DDF TUZVO, 2018. 49 pages.The goal of the thesis is to develop a literary overview of nitrogen and its compounds in terms of their hazards. Inorganic compounds have been described as ammonia, nitrogen oxides, hydrogen cyanide, cyanides, hydrazine, nitric acid and its salts, nitrous acid and its salts, nitrobenzene, trinitrotoluene, nitromethane and aniline. We focused on physical and chemical properties, occurrence and use and pointed to the dangers of flammability and toxicity of nitrogen and its compounds.
