This master thesis is dedicated to the determination of concentration of selenium and mercury in seafood. The theoretical part is devoted to the selenium characteristics, toxicity and occurrence of the biochemical functions of selenium and the relation of selenium and mercury in fish. The practical part deals with the determination of selenium and mercury in fourteen species of fish that have been purchased fresh or vacuumed in chains store in the Czech Republic. Analysis of the selenium content was performed by atomic absorption spectrometry with electrothermal atomization. Determination of the total mercury content was performed with using atomic absorption spektrometer AMA 254. Results of total mercury contents were compared with legislative limits as per Commission Regulation (EC) No. 629/2008. Selenium Health Benefit Values Se-HBV were calculated.
