Effect of Nanoparticles on Plant Metabolism

Charles University Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Mgr. Tereza CYRUSOVÁ Supervisor: prof. Ing. Barbora SZOTÁKOVÁ, Ph.D. Consultant: RNDr. Radka PODLIPNÁ, Ph.D. Title of Doctoral Thesis: Effect of Nanoparticles on Plant Metabolism Along with the expansion of nanotechnologies, which are used in many disciplines, the field of nanotoxicology has recently been developed. It deals with the negative effects of engineered nanoparticles on the environment and biota. Considerable attention has already been paid to the toxicity of nanoparticles to plants, however, the mechanisms responsible for their effects are not fully understood yet. At the same time, the possible positive effect of nanoparticles on plants has been investigated in recent years. The aim of our work was to study and evaluate the effect of nanoparticles on the growth of selected plant species and to evaluate their phytotoxicity. We focused on the study of nanoparticles in the form of metal oxides. The content of accumulated metals in germinating plants of mustard (Sinapis alba L.), in in vitro cultures of true-fox sedge (Carex vulpina L.) and the concentration of metal ions released into the culture media were measured by atomic absorption spectrometry (Cu, Fe, Mn, Zn). and inductively...

Charles University in Prague, Faculty of Pharmacy in Hradec Kralove Department of analytical chemistry Candidate: Bc. Tereza Cyrusová Consultant: Prof. RNDr. Petr Solich CSc., Prof. Angelina Pena, Ph.D. Diploma thesis title: Optimization of HPLC method for the determination of polycyclic aromatic hydrocarbons in cephalopods Polycyclic aromatic hydrocarbons (PAH) are compounds dangerous for both environment and human health. Monohydroxyderivatives of PAH are their very important derivatives that arise in the detoxification process of PAH in the body of human and other organisms. Some monohydroxyderivatives of PAH have been assessed as a marker of PAH exposure. The main goal of this work was to optimize the analytical method for determination of selected PAH monohydroxyderivatives (1-hydroxypyrene, 2-hydroxyfluorene, 1-hydroxynaphtalene, 1-hydroxyacenaphtene) in the bodies of cephalopods. The used method was high-performance liquid chromatography with fluorescence detection. The detection wavelengths and mobile phase composition were selected. A column study, verification of antioxidant application and degradation study were carried out. Subsequently the optimization of conditions for determination of all four substances simultaneously was done. Based on these steps, for the partial experiments ACE...
