Evaluation of energetic byproducts via selected ecotoxicity tests

The topic of bachelor thesis is the study of ecotoxicity of energetic byproducts generated from the power industry. The theoretical part is focused on current problems concerning waste ecotoxicity testing namely on needs of ecotoxicity testing not only in terrestric but also in aquatic arrangement. In practical part selected energetic byproduct were evaluated via Acute toxicity test and Avoidance test on soil organism earthworm (Eisenia fetida) and Plant root growth inhibition test on letuce and onion (Lactuca sativa a Allium cepa). Luminescent bacteria test on Vibrio fischeri was also used. Obtained results served for evaluation of potential ecotoxicity of energetic byproducts discussion. It was found that test in contact arrangement is very important for complex evaluation of negative effects of matrices entering the ecosystem. Also the importance of test on luminescent bacteria Vibrio fischeri is not negligible, because provides additional information of effects on representatives of destruents as an important ecosystem function part
