Assessment of contamination of sewage sludge from wastewater treatment plant by drug residuals
Dvořáková, Petra ; Stoupalová, Michaela (referee) ; Vávrová, Milada (advisor)
The aim of diploma thesis was finding of the method for the determination of drug residua in sewage sludge from wastewater treatment plant. Selected sulfonamide and diaminopyrimidine antibiotics, which are used in human and veterinary medicine, were selected as target comopounds. They are discharged to the sewer systems together with the urine and faeces and enter the sewage treatment plant, where they are not completely removed. They can be found in treated waste water or in sewage sludge. They can enter to the environment, where they can induce negative effects on organisms in soil and water ecosystem. An optimized method was used for identification and determination of these antibiotics in real samples from the large-scale waste water treatment plant in Brno-Modřice and from the waste water treatment plant situated in the area of Veterinary and Pharmaceutical University Brno. Antibiotics were extracted from sewage sludge by ultrasonic and by pressure solvent extraction (PSE). Waste water and sewage sludge real samples were concentrated and cleaned by solid phase extraction (SPE). For determination these antibiotics high performance liquid chromatography with diode array detector (HPLC - DAD) was used.

Sulfonamide residues in sediment and sludge from wastewater treatment plants
Chaloupková, Petra ; Lacina, Petr (referee) ; Vávrová, Milada (advisor)
The aim of the bachelor’s thesis was a method optimalization for extraction of sulfonamides from sediment and sewage sludge samples from wastewater treatment plants. This optimized method was used for analyzing sulfonamides in real soil and sewage sludge samples. Antibiotics are commonly used as a prevention and medicament for human and animals. Drugs and their residues enter to wastewater treatment plants within excrements and then they can be a part of sewage sludge or they can occur in treated water. It can also enter environment as a part of soils or sediments. Three extraction methods were chosen for optimizing; a pressurized solvent extraction, a microwave-assisted extraction and an ultrasonic extraction. Extracts were cleaned by solid phase extraction and analysed by liquid chromatography with diode array detector.
