Ekotoxicita pěnových hasebních prostředků
Belisová, Mária ; Vávrová, Milada (oponent) ; Zlámalová Gargošová, Helena (vedoucí práce)
Táto bakalárska práca sa zaoberá ekotoxicitou vybraných hasiacich prípravkov so zameraním na penotvorné látky (tenzidy) obsiahnuté v penových hasiacich prístrojoch. Jedná sa o pevné zmáčadlá TS TURBO a TS ECO. V tejto bakalárskej práci bol posudzovaný ich ekotoxikologický účinok na vybraných testoch ekotoxicity v akvatickom prostredí, na vodnej rastline Lemna minor a na kôrovcovi Thamnocephalus platyurus. Ide o sladkovodné organizmy, na ktorých je možné rýchlo a pomerne jednoducho stanoviť mieru kontaminácie vody. Ďalej boli tieto hasiace prostriedky testované z hľadiska akútnej toxicity pre pôdne organizmy ekotoxikologickými testami v kontaktnom usporiadaní na dážďovke hnojnej Eisenia fetida a na semienkach šalátu siateho Lactuca sativa. Nakoniec bola testovaná biodegradácia oboch prostriedkov, kedy bola pozorovaná zmena v ekotoxikologickom účinku po 24 hodinách a po jednom mesiaci. Zmena ekotoxicity bola opäť otestovaná na organizme Thamnocephalus platyurus. Na základe výsledkov testov boli spočítané hodnoty LC50 a IC50 pre testované hasiace prípravky a bola porovnaná ich ekotoxicita.

Assessment of the ecotoxic effect of plasma-activated solutions
Belisová, Mária ; Šimečková,, Jana (oponent) ; Zlámalová Gargošová, Helena (vedoucí práce)
This master‘s thesis deals with ecotoxicity assessment of plasma-activated solutions. Various plasma-activated solutions were prepared in the experiments. In the vast majority of tests, it was plasma-activated tap water – PAW. Depending on the test organism, dilution water was further processed, namely dilution water for Thamnocephalus platyurus and Daphnia magna. In this master‘s thesis the ecotoxicological effects were assessed through aquatic ecotoxicity tests with an aquatic plant Lemna minor, on a crustaceans T. platyurus and D. magna and on agricultural crops Lactuca sativa and Allium cepa L. . Crustaceans are fresh-water organisms on which the water contamination can be quickly and quite easily assessed. These plasma-activated solutions were also tested for acute ecotoxicity of soil organisms by ecotoxicological contact tests with Eisenia fetida, springtails Folsomia candida and seeds of L. sativa. Tests on T. platyurus and D. magna were performed in time intervals and a change in mortality was observed depending on PAW concentration. If the test results allowed, the LC50, IC50, A and NR escapism values were calculated. When the measured and calculated values did not allow such a calculation, the overall effect of PAW on organisms was assessed and a significant difference was calculated for the L.sativa root growth inhibition test. The final results showed that PAW has an ecotoxic effect on aquatic organisms, while it has rather beneficial effects on terrestrial organisms.
