This diploma thesis is focused on an analysis of mercury content in eatable mushrooms. Theoretical part describes transmission of mercury from environment to the soil, next to the mushrooms. Practical part was focused on the determination of total mercury content. Determination of mercury content was provided by atomic absorption spectrometer AMA 254. The samples were obtained from forests in the Czech Republic and Slovakia in 2017 and 2018 and from supermarkets in the Czech Republic. This thesis compares mercury concentration among various types of mushrooms obtained from various collection sites. Moreover, the contents were compared within different collection years, country of origin or size of mushroom. Furthermore, average mercury contents in mushrooms obtained from forests and supermarkets were compared. The highest concentration was found in wild-grown Agaricus bisporus and Macrolepiota procera, which have been grown in areas with higher mercury presence. The highest hazard index was calculated in this samples, too. The highest bioconcentration factor was calculated in Boletus reticulatus
