Walachová, Klára
This thesis deals with the evaluation of toxicity and soil leachate from landfill Těmice. The theoretical part focuses on the characteristics of municipal waste landfill and process description. Another part is devoted to the field of ecotoxicology and describing its basic methods. The practical part describes the selected landfill and performing the assay inhibition of white mustard (Sinapis alba L.) for leachate water from landfill. The work also includes the test phytotoxicity of soil by Phytotoxkit. It focuses on the description of this method, workflow and work aids. In conclusion, the evaluation of both tests, which involve the calculation of root growth inhibition for each concentration of the test substance. The work is complemented by photographic documentation carried out laboratory tests and landfill.
Hodnocení fytotoxicity kalů z vybraných čistíren odpadních vod
Šindelář, Ondřej
The diploma thesis “The assessment of the phytotoxicity of sludge from selected sewage treatment plants“ deals with the current situation of the sludge treatment and disposal and the assessment of phytotoxicity of sewage treatment sludge. The sewage treatment sludge comes into existence during the process of sewage treatment. Nowadays is sludge landfilling from the point of view of nature protection and according to the legislation on the last place in a way of handling. Additionally, the thesis pays attention to the legislation related to the sewage treatment sludge and also statistical data concerning the production and the way of handling of the sewage treatment sludge. The practical part of the diploma thesis is focused on the description of two sewage treatment plants, namely Třebíč and Náměšť nad Oslavou. Subsequently were made several laboratory experiments with the sewage treatment sludge samples from the mentioned sewage treatment plants. At the sewage treatment sludge samples were assessed the phytotoxicity level by the testing set Phytotoxkit. Specifically was determined an inhibitive/stimulative effect on the growth of the root. The testing plant was a white mustard (Sinapis alba L.).
