Options determination of synthetic fragrances in wastewater
Kašparová, Jarmila ; Zlámalová Gargošová, Helena (referee) ; Vávrová, Milada (advisor)
Synthetic fragrances (musk) are artificially made organic compounds, which are used as fragrances in pharmaceutical and cosmetic products. The presence of musk is proven in all environmental compartments. However, the greatest attention is paid to purified waste water, which is a frequent source of pollution of surface water. The physico-chemical properties of musk compounds cause their accumulation in the living and non-living components of the ecosystem, where they behave as persistent pollutants. The presented bachelor thesis deals with the problem of determining individual musk compounds of all groups side by side. In the bachelor thesis, nineteen musk compounds of four groups, nitromusk compounds, macrocyclic musk compounds, linear musk compounds, polycyclic musk compounds were studied. The basis of this work was to optimize the method for determining all groups of musk compounds side by side, evaluating and interpreting the results. Solid phase microextraction (SPME) was used as a method for extracting analytes. Gas chromatography in conjunction with mass spectrometry was used for the final analysis, as a detector was used for a Time of flight analyzer.

Contamination of environment of musk compounds
Tobková, Lenka ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
Synthetic musk compounds are artificial organic substances commonly used as fragrant constituents of personal care products as parfums, cosmetics, detergents, in-house cleaning and washing agents. Given their large area of applications and their ability to be persistent, they leaked into all parts of ecosystem, especially aquatic one. There have been a big focus on studiyng these compounds, their properties and fate in the different parts of ecosystems in the last years. The aim of master's thesis was carry out the determination of five representatives (habanolide, exaltolide, ambrettolide, musk MC4 and ethylene brassylate) of macrocyclic musk compounds in waste water samples from influent and effluent of three water treatment plants (WWTP Brno-Modřice, WWTP Lednice and WWTP Mikulov). One of the main tasks was to perform a method optimisation for the determination of selected musk compounds in waste water and evaluation and interpretation of the results. Solid phase microextraction (SPME) technique was used for the extraction of analytes, consequently gas chromatography-mass spectrometry was used for analysis of selected analytes. Following evaluation the removal efficiency of musk compounds in the waste water treatment plant was assessed.
