Drugs and possibility of their elimination in sewage waters
 Křivánková, Zuzana ; Repková, Martina (referee) ; Vávrová, Milada (advisor)
This bachelor thesis deals with issue of increasing consumption of pharmaceuticals and its influence on the environment. In the Czech Republic the pharmaceuticals from the benzodiazepine group are still widely prescribed and used by patients. There was tracked four representatives of this group alprazolam, bromazepam, diazepam and oxazepam which are indicated for therapy of insomnia, psychiatric diseases but also like a general anesthetics or antiepileptics. Presence of this pharmaceuticals is being repeatedly confirmed in wastewaters and surface waters troughout the whole Europe and other developed countries even though their negative effects for the water ecosystem are known. The target od this thesis is to optimalizethe methods for determination of choosen pharmaceuticals in watewaters in Brno and surrounded area. There was also evaluatedthe hazard level for water ecosystem related to the presence of pharmaceuticals in target matrices which were the wastewaters from wastewater treatment plants in towns Brno – Modřice and from two another towns in south Moravia. Concentrations of the pharmaceuticals were tracked in the influents and effluents. The analytes were isolated from the matrices by solid-phase extraction (SPE) and quantificated by ultra-high performance liquid chromatography (UHPLC) with detection by the diode array (DAD).
