Evaluation of ecotoxicity of selected chemicals with using algal test.
 Kosárová, Hedvika ; Pavlovský, Jiří (referee) ; Doležalová Weissmannová, Helena (advisor)
This bachelor thesis deals with the ecotoxicity of 2 - [(2,6-dichlorophenyl)aniline] benzene acetic acid (diclofenac), ?-methyl-4-(2-methylpropyl) benzene acetic acid (ibuprofen) and mixture of cadmium and diclofenac and studies the above using algal toxicity test in accordance with ISO 8692. The theoretical part describes the issue of pharmaceuticals in the environment, and characteristics of standards algae tests and alternative tests. Freshwater green algae Desmodesmus subspicatus were used as testing organisms in all the implemented algal toxicity tests. By the means of these tests, the IrC50 values for the standard substance potassium dichromate, the drugs diclofenac and ibuprofen and cadmium were determined. The toxicity of cadmium in mixture with diclofenac was also evaluated.

Application of preconcentration/separation techniques for the determination of platinum in the environment by atomic spectrometry
 Kosárová, Hedvika ; Čelechovská, Olga (referee) ; Komendová, Renata (advisor)
This thesis deals with optimization of conditions for the determination of platinum by electrothermal atomic absorption spectrometry. The theoretical part describes the occurrence of platinum in different part of the environment, its physical and chemical properties, transport and bioavailability. There is also evaluated appropriate method for determination and preconcentration of platinum. The experimental part describes advance of optimize the measurement conditions for ETA-AAS, further is describes optimization of condition for SPE and work with real samples on which are applied this conditions.
