Questions of pollutants determination in waste waters
Tandler, Ágnes ; Čáslavský, Josef (oponent) ; Vávrová, Milada (vedoucí práce)
In this bachelor thesis of theoretical character is being solved the problem of the presence of harmful substances in waste waters. Concerning inorganic substances attention is focused to lead and cadmium and their compounds. From the wide row of harmful organic compounds are chosen surfactants, polycyclic aromated hydrocarbons and polychlorinated biphenyls. There are described their chemical properties, origin and appearance in waste waters. This work also includes their analytical determination by mobile analysis and confirmatory methods. The last chapter includes standard operating procedure of the confirmatory fotometric method of determination of anionic surfactants, which is suitable for accredited laboratories.

Bioavailability of metals species in water ecosystem
Tandler, Ágnes ; Řezáčová, Veronika (oponent) ; Vávrová, Milada (vedoucí práce)
The free metal ion concentration is often only a small fraction of the total metal concentration in the environment. Despite their small amount, in most of the circumstances the free metal ion concentration is the key factor in determining metal bioavailability and toxicity for the organisms. The Donnan membrane technique is able to measure the free metal ion concentration and in this thesis, it is validated for metal mixtures (Pb + Cu) in absence and presence of small organic ligand mixtures. Lead and copper are environmental relevant metals due to their toxic properties and different binding properties relative to the studied ligands.
