The thesis deals with determination of selected nutrients (copper, zinc, iron) in nuts. In total, 33 samples, bought in retail chains in Czech Republic, were analysed. The theoretical part of the thesis is focused on characterisation of individual nuts including other fruits, which are consumed as nuts. In the practical part, contents of copper, zinc and iron were measured by the atomic absorption spektrometry method. From the results, it is clear that the highest amount of copper was found in Brazil nuts. The lowest amount of copper was found in macadam nuts. Overall the highest content of zinc within all types of nuts was found in pine nuts and the lowest amount of zinc was determined in coconut and edible chestnuts. Iron was the most contained in alaburks, cashews and pine nuts. The lowest quantitty of this element was measured in edible chestnuts.
