Toxicity of fine and ultrafine particles from combustion processes
Berková, Helena ; Köbölová, Klaudie (referee) ; Adamec, Vladimír (advisor)
The bachelor thesis deals with the toxicity of fine and ultrafine particles from biomass combustion. The theoretical part is focused on the current state of this issue from the origin, physicochemical properties, mechanism of toxicity of particles, to their impact on the environment and human health. The following is an overview of tests for determining the toxicity of fine and ultrafine particles. The experimental part is devoted to the actual sampling of biomass combustion, their characterization, cultivation of the tested organism and toxicity tests. The results of acute toxicity tests are expressed in terms of percentage mortality values and then the toxicity is evaluated.

Risks associated with the use of biochar in the terrestrial ecosystem
Valeeva, Adeliia ; Řezáčová, Veronika (referee) ; Zlámalová Gargošová, Helena (advisor)
The aim of this bachelor thesis was to assess the ecotoxicity of biochar produced from sewage sludge in Ingolstadt. Biochar is one of the carbon storage options and it’s applied to the soil. Biochar has an effect not only on the terrestrial ecosystem in direct contact of organisms with the sample, but also on aquatic in the leaching of substances from biochar into water. Therefore, contact and aquatic tests were chosen to assess the ecotoxicological effect. The representative of the decomposers was the earthworm Eisenia fetida, the primary producer – the plant Lactuca Sativa and the Daphnia magna was chosen from the aquatic organisms. The test results differed slightly, but the lowest negative effect on the test organisms was shown by soil samples with the addition of 5 g/kg and 10 g/kg granular biochar.
