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.

Evaluation of occurence of musk compounds in water ecosystem
Tobková, Lenka ; Zouhar, Libor (referee) ; Vávrová, Milada (advisor)
This bachelor’s thesis is concerned with synthetic musk compounds and their presence in the environment, particularly in water ecosystem. The thesis contains fundamental classification of synthetic musk compounds together with specification and detailed description of their most significant representatives. Among them are linalool, citronellol, and isobornyle acetate which will be studied further in master’s thesis. Fundamental physical-chemical properties of these odoriferous compounds and their toxicological and environmental impact are studied. Also part of this thesis is a detailed description of synthetic musk compounds’ analytical determination.
