Ecotoxicity of selected extinguishing agents

By Markéta Konečná

Abstract

The dynamic development of industry and the constant production of new substances affecting the environment is currently one of the priorities of the interests of the human population. This thesis is focused on the ecotoxicological evaluation of selected extinguishing agent which are applied in case of fire. They must effectively extinguish fire because a live protection and material resources in any case very important, but Theky should be also environmentally friendly. In this work were tested surfactants, which are the main component of foaming extinguishing agent with the following commercial names: STAMEX F-15, F-15 EXPYROL, MOUSOL APS F-15, FINIFLAM F-15 and PYROCOOL B. Since surfactants have a negative impact mainly on aquatic ecosystem assessment were mainly used ecotoxicity tests using aquatic organisms. Test organisms were aquatic crustacean Daphnia magna and Thamnocephalus platyurus aquatic dicotyledons plant Lemna minor and terrestrial monocotyledons plant Sinapis alba. Based on the results of the tests were values of LC50, EC50 and IC50 for the tested substances determined and their ecotoxicity compared
