Phytoextraction of non-steroidal analgetics
Bažilová, Blanka ; Smrček, Stanislav (advisor) ; Zedník, Jiří (referee)
In present time environment is considarably contaminated by various diversed polutants mainly because of human activity. Part of this dissertation deals with problem of contaminents spreading into environment. Further more it summarizes particular options of xenobiotics removal from waste and subterraneous waters and it mostly focuses on new inovative methods decontamination methods of polluted areas based on vegetative biotechnologies. This study comprises knowledge about plants abilities and usage by transformation and degradation of nonsteroid analgesics, which belong to most common and mass used drugs. Goal of dissertation was to observe fate and transport in present time used nonsteroid analgesics and fytoextraction efficiency evaluation of such a substances from liquid nutrient medium with sunflower and corn. For determination of chosen nonsteroid analgesics (piroxicam, nimesulid, ketoprofen a paracetamol) was developed and optimalized analytical procedure which consisted of extraction and determination by HPLC-MS method. Results indicate that studied nonsteroid analgesics are very good extracted by plants. Biggest phytoremediation potential was proved for ketoprofen, which was consumed by plants more than other nonsteroid analgesics.

Radionuclide accumulation by plants cultivated under laboratory and real conditions
Dvořáková, Barbora ; Soudek, Petr (advisor) ; Petrová, Šárka (referee)
Environmental contamination with radionuclides is a growing problem in many places all over the world. Phytoremediation works as a safety alternative for some energy demanding and expensive methods of soil cleaning. Phytoremediation uses various abilities of plants and microorganisms to change the mobility of contaminants in soil as well as soil properties. The uptake and transport of radionuclides to plants is affected by their chemical form. Radionuclides in soil are taken up by plants and can thus enter the food chain. The number of nuclear accidents such as Chernobyl and Fukushima operation of nuclear power plants, mining and processing of uranium ores and testing of nuclear weapons result in global contamination of our planet by artificial radionuclides.
