Study of glyphosate degradation in water plasma application
Vašinková, Alena ; Vávrová, Milada (referee) ; Mravcová, Ludmila (advisor)
This work deals with the current problem of increasing concentrations of glyphosate in groundwater and wastewater due to insufficient efficiency of methods used in wastewater treatment. From this point of view effective removing of glyphosate from water have to be developed by new methods and technological processes. The methods used so far in wastewater treatment plants should be replaced or supplemented by advanced oxidation processes. The practical part of this work is devoted to glyphosate and its degradation in water by plasma. Samples were taken sequentially during plasma application and further evaluated by LC/MS selected as suitable analytical methods. The aim of this work was to determine the efficiency of plasma in water with admixture of glyphosate.

Analysis of pesticides in the environment using the QuEChERS method
Vašinková, Alena ; Řezáčová, Veronika (referee) ; Mravcová, Ludmila (advisor)
This thesis focuses on pesticides in the environment, more specifically in cereals. Pesticides were monitored in various samples of cereals (barley, rye, oats, and wheat) within the thesis. The monitored substances were isolated in selected samples and concentrated using the QUECHERS method. Gas and liquid chromatography were used to determine pesticides. The theoretical part consists of the common types of pesticides, divided by the ease with which these substances into food and their impact on humans and environment. It also mentions current health protection legislation and environmental legislation.
