The ecotoxicological evaluation of musk compounds
Lapčíková, Alena ; Beklová, Miroslava (referee) ; Doležalová Weissmannová, Helena (advisor)
This master’s thesis is focused on evaluation of synthetic musk fragrances using ecotoxicity tests. Four musk fragrances were tested – Galaxolide, Tonalide, Musk ketone and Musk xylene. Four alternative ecotoxicity tests with living organisms, one standard ecotoxicity test and three fytotests were used for evaluation of ecotoxicity. Alternative tests were performed on crustaceans Daphnia magna and Thamnocephalus platyurus, brine shrimp Artemia salina and rotifer Brachionus calicyflorus. Root growth inhibition test of Sinapis alba, root growth inhibition test of Lactuca sativa, root growth inhibition test of Allium cepa and growth inhibition test of Lemna minor were performed in the terms of fytotests. On the basis of the results the values of EC50, IC50 and LC50 were determined and the ecotoxicity of musk compounds was evaluated.

Hodnocení stavu životního prostředí: Monitoring cizorodých látek v potravních řetězcích: Celkový pohled na zátěž kontaminanty z hlediska možného ohrožení zdraví populace
Vysoká škola chemicko-technologická v Praze, Praha ; Volka, Karel ; Slanina, Přemysl
Zpráva prezentuje hodnocení vybraných kontaminantů v souladu s principy analýzy rizika. Objasňuje principy současného toxicologického posuzování a kritické a inovativní hodnocení možného zdravotního rizika ve vztahu k zatížení potravních řetězců kontaminanty. Jsou diskutovány vlivy cizorodých látek na porušení hormonální rovnováhy. Je zdůrazněna nezbytnost komunikace s odbornou i laickou veřejností onebezpečnosti škodlivých kontaminantů, která by mohla vést k omezení zdravotního rizika. Zároveň jsou uvedeny některé přístupy, které vedou ke snižování expozice konzumentů potenciálně škodlivým kontaminantů.
Influence of common sources of communal pollution on aquatic environments
ŠATRA, Václav
The aim of the thesis was to assess the impact of current sources of sewage treatment plant (STP) located upstream on the contamination of the aquatic environment. In 2009 contamination assessment was carried out at three selected sites located within the municipal sewage treatment plant and at three sites located above these potential sources of pollution. Brown trout (Salmo trutta m.fario L.) was the indicated species. The presence of MUSK materials , brominated flame retardants (BFRs) and organochlorinated persistent pollutants (POPs) was being detected within the selected samples of fish muscles and sediments.
