Determination of antibiotics in the wastewater
Suková, Petra ; Tulková, Tereza (referee) ; Vávrová, Milada (advisor)
This thesis deals with problem of antibiotics, substances used in the prevention and treatment of infectious diseases in human and veterinary medicine. Have been discussed aminopenicillins antibiotics from the group of antibiotics, particularly ampicillin and amoxicillin, which are one of the most frequently prescribed antibiotics in both the Czech Republic and in the world now. Drug substances together with wastewater pass into the wastewater treatment plant where sewage process does not remove the drug from the treated water entirely. Drug substances can be penetrate into the other components of the environment in the result, especially in surface water and soil, where they can have adverse effects on organisms living there. For the isolation of analytes from samples of wastewater was selected solid phase extraction (SPE). For final analysis of antibiotics was used method of ultra-high performance liquid chromatography with UV-VIS detection with diode array detector and method of liquid chromatography with mass spectrometric detection. Based on the optimization of analytical techniques was especially ampicillin chosen as analyte isolated from the matrix of waste water. Analysis of the wastewater was conducted for a total of four days of influent and effluent wastewater treatment plant in Brno-Modřice and wastewater treatment plant which is situated in area of the Veterinary and Pharmaceutical University in Brno.

The issue of determination of beta-blockers in surface waters
Košík, Juraj ; Píšťková, Veronika (referee) ; Vávrová, Milada (advisor)
This bachelor´s thesis deals with the issue of increasing concentration of pharmaceuticals in the environment. The most worldwide prescribed medications with the most frequently detection in the environment are -blockers. These compounds are clinically important drugs which are extensively used for the treatment of cardiovascular disorders such as hypertension, arrhythmia and angina pectoris. It is important to monitor the concentration levels of blockers in aquatic environment due to their acute and chronic toxicity towards aquatic organisms. This study is focused on development and optimization of analytical method of determination of these compounds. The monitored matrixes were surface water from two rivers, Váh (Slovakia) and Dyje (Czech Republic) and waste water form waste water treatment plant (WWTP) Brno-Modřice. The analytes from water samples using solid phase extraction (SPE) were isolated. For the final analysis ultra-high performance liquid chromatograph with UV-VIS detection using diode array detector (DAD) was used. As the target compounds atenolol, metoprolol and propranolol were selected.

Determination of selected drugs (beta-bloskers) in surface water
Kříž, Jiří ; Zlámalová Gargošová, Helena (referee) ; Vávrová, Milada (advisor)
This bachelor's thesis discusses the issue of pharmaceuticals in the environment. -blockers are one of the most prescribed medications with the most frequent detection in the environment. These compounds are clinically important drugs used to cure cardiovascular disorders such as hypertension, arrythmia and angina pectoris. Due to their acute and chronic toxicity towards aquatic organisms it is important to monitor the concentrations levels. This study is focused on optimization of analytical method to determine these compounds. The matrix examined was a waste water from a waste water treatment plant (WWTP) Brno Modřice. A solid-phase extraction (SPE) was used for the isolation of analytes in a waste water samples. A method of high performance liquid chromatography (HPLC) with the UV-VIS detection using a diode array detector (DAD) and mass spectrometry (MS) was used. Target analytes were atenolol, metoprolol and bisoprolol.
