DVOŘÁKOVÁ, Hana
The aim of this work was to determine the concentrations of rubidium, cesium, lithium, strontium and supplemental elements of copper, iron, manganese and zinc in samples of edible mushrooms and to compare the measured concentrations with the studies mentioned in the literary research. In addition to the results of the studies, the literary research contains brief informations about mushrooms, individual elements, the used method and the monitored location. For the purposed of the practical part, 19 samples of nine edible mushrooms species were collected from the vicinity of a lead smelter in the village of Podlesí near Příbram. The samples were the first processed by microwave digestion and then analyzed by AAS (atomic absorption spectrometry). The whole practical part of the thesis was carried out in the laboratory of the Departemnt of Applied Chemistry, Faculty of Agriculture of the University of South Bohemia in České Budějovice. The analysis results were recorded in tables, statistically and graphically processed an evaluated in the discussion. From the analysis we found the species of mushoom with the most cumulate metals ability is a toadstool rosacea. Among the analyzed samples we found the highest concentration of strontium (22,5 mg/kg), lithium (0,6 mg/kg), iron (223,0 mg/kg) and manganese (69,7 mg/kg). On the other hand, the least cumulative species was boletus brown with the lowest concentrations of copper (10,1 mg/kg), iron (29,5 mg/kg) and manganese (5,2 mg/kg) being determined. The less cumulative species was also boletus edulis, which was found to have at least strontium (2,2 mg/kg) and lithium (0,3 mg/kg). It is worth mentioning the larch bolete, in which we have determined the greatest concentration of rubidium (364 mg/kg) and cesium (11,7 mg/kg), but the least of zinc (68,7 mg/kg). Likewise, a parasol mushroom absorps copper to a large extent (255 mg/kg), but on the contrary it contained the least cesium (0,5 mg/kg) and rubidium (11,8 mg/kg).

The research of the bachelor's thesis also uses a quantitative method, namely testing using a test battery MOBAK-KG, which contains 8 movement tests (4 with a ball, 4 with own body). Using a battery, we test children in both kindergartens and assess differences in the level of motor competencies. Subsequently, we process the results and evaluate them using basic description and calculation of arithmetic means. Result: According to the SEP analysis of both kindergartens, I came to the conclusion that the SEP of a private kindergarten with a sports focus is more focused on sports and a healthy lifestyle, but even the SEP of a public kindergarten does not forget the importance of physical activities....
