Stanovení rtuti a jejích forem v rybích výrobcích

This thesis is dedicated to the determination of mercury and their forms in fish products. The theoretical part is devoted to the toxicity of mercury, mercury in the environment and speciation of mercury. The practical part deals with the determination of mercury and its forms in the four types of fish products which were bought in the supermarkets in the Czech Republic. The contamination level was compared with the limits in Czech legislation. Atomic absorption spektrometry was used for the total mercucy content analysis and high performance liquid chromatography with could vapor technichique with atomic fluorescence detection was used for determination of methylmercury and inorganic mercury species
