Zinc in environment and methods of remediation
Landová, Ludmila ; Michálková, Zuzana (advisor) ; Dvořáková Březinová, Tereza (referee)
Zinc and other heavy metals cause negative effects on both the environment and human health. Depending on the concentration of zinc in the ecosystem, it can produce unwanted effects in the environment and on the human. Due to pollution, vegetation may not be able to grow on the contaminated soils, which can further result in strong soil erosion. For these reasons, remediation of soils contaminated with risk elements is necessary to minimize their impact on ecosystems. This bachelor thesis describes properties, utilization, stability and behavior of zinc and other risk elements in the environment, including the removal from contaminated soils using remediation methods.
The experimental part aims at the influence of AMO and Sm-AMO on stability of zinc and risk elements in contaminated soil together with the adsorption kinetics of zinc onto these two materials. The results detected high efficiency of Sm-AMO on sorption of zinc and lead in the test kintetics of adsorption. For most heavy metals
having a similar effect, when Sm-AMO is as efficient as AMO, any cases, it has a higher efficiency.

Popular perception of death and its reflection in chapbooks
Landová, Ludmila
There are many ways to study death in chapbooks. Because in the majority of cases these texts take the form of songs, as a first resort offers themselves methods of the folklore studies. However, in this text an ethnological point of view is being applied in order to comprehend the popular perceptions of death and the ways these are reflected in chapbooks
