The effect of dump waters on the quality of surface stream in Czech Republic
Samšuková, Eva ; Benešová, Libuše (advisor) ; Křenková, Marcela (referee)
A landfill leachate is a chemical solution generated in the waste materials that are dumped in a landfill. According to the increasing amount of waste produced worldwide the risk that leachate water gets out of a landfill and contaminates with contained pollutants surrounding environment, e.g. nearby surface water, rises. The aim of this thesis is to evaluate the effect that leachates have to surface water in the Czech Republic. The research was built on primary data that had been obtained in several landfills in the Czech Republic. Important sources were also obtained through the secondary literature. Possible influence of leachates is also outlined by chemical calculating illustrating a hypothetical situation of leaking landfill water to a stream. My research showed that the impact of landfill water on surface water presents a great risk. It can occur during ordinary operations of the landfill operations - due to instable technical installation or due to dumping waste with a different extract conditions, but also as a consequence of extraordinary situations (e. g. storms). Surface water is mostly polluted with heavy metals, chlorides or nitrogen in variety of its forms. High concentration of organic matters is also detected by COD and BOD indicators. Exceeding legal limits threatens the whole surface...

Hodnocení toxicity průsakových vod a půd ze skládky odpadů
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.
