Originální abstrakt

Fires could have a negative impact on the environment not only through the production of many toxic products of burning like PAHs, PCDDs, PCDFS, CO etc. but also through application of modern fire extinguishing agents, especially foams based on surfactants. In the fight against fires air‑mechanical extinguishing foams are often used, which are available in several basic modifications, i.e. protein foam agents, synthetic foam agents and alcohol‑resistant foam agents. Penetration of these substances into the environment causes water and soil contamination and disruption of waste water treatment processes. It results in significant acute toxicity of contaminated matrices and in transfer of pollution to the other environmental compartments. In the soil environment the sorption of various constituents of fire‑fighting foams on soil particles can take place and this could lead to the reduction of acute toxicity for aquatic ecosystem, but on the other hand it could increase of acute toxicity for soil organisms. Our work is focused on the evaluation of effects of the most frequently used extinguishing agents on selected aquatic and terrestrial organisms.
