Ecotoxicity of Firefighting foam
 Belisová, Mária ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
This bachelor thesis deals with ecotoxicity of selected fire extinguishing agents concentrated on surface-active agents (surfactants) contained in foam fire extinguishers. Tested substances were solid humectants TS TURBO and TS ECO. In this bachelor thesis the ecotoxicological effects were assessed through aquatic ecotoxicity tests with an aquatic plant Lemna minor and a crustacean Thamnocephalus platyurus. They are fresh-water organisms on which the water contamination can be quickly and quite easily assessed. Also these fire extinguishers were tested for acute ecotoxicity of soil organisms by ecotoxicological contact tests with Eisenia fetida and seeds of Lactuca sativa. Finally, the biodegradation of both fire extinguishing agents was tested, observing the change between 24 hour exposition and one month exposition of tested agents. The change of toxicity was tested with Thamnocephalus platyurus. Based on experimental results of extinguishing agents the value of LC50 and IC50 was calculated and the ecotoxicity was compared.
