Original Abstract

Ecotoxicological evaluation of unconventional matrices The energetic by-products (EBP) are a part of energetic wastes covering solid residues of fuels combustion and also of flue-gas cleaning. Their following use could impact the terrestrial ecosystems and subsequently in certain cases also the aquatic ones. In this study five samples of energetic by-products were subjected to ecotoxicological testing via direct contact phytotoxicity tests and via testing of water leaches of these samples in accordance with methodology described in valid Czech legislation on waste management using Embryophyta. For ecotoxicity testing of the energy by-products water leachates the root growth inhibition test on following plant species was used: white mustard (Sinapis alba), turnip kohlrabi rape (Brassica rapa) and oats (Avena sativa). For the evaluation of ecotoxicity in direct contact arrangement the following phytotoxicity tests were selected: germination and growth of higher plants, brassica oilseed rape (Brassica napus) and oats (Avena sativa). Furthermore, the test of limit concentrations of waste on the plant Brassica napus and screening tests poppy germination of lettuce (Lactuca sativa) were performed. Water leachates exhibited very low ecotoxicity; it was not possible to calculate the values of 72hIC50 in any case. In accordance with waste management legislation that means that none EBP exhibits ecotoxicological property H-14 (ecotoxicity). On the other hand by the application of direct contact phytotoxicity tests the ecotoxicity was demonstrated in four of five tested samples. On the basis of obtained results the ecotoxicity of various energetic by-products was assessed and the need of solid matrices testing in contact arrangement was discussed.
