Ecotoxicological assessment of contaminated matrices discharged into the ecosystem
Urbanová, Veronika ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
This diploma thesis evaluates the influence of contaminated matrices introduced into the ecosystem in terms of ecotoxicity. It is focused mainly on matrix generated by anthropogenic activities, especially waste of various origin - industrial, energetical, biodegradable and more. For experimental purposes sewage sludge as the bulk waste with the ever-increasing production was selected. Sewage sludge was tested at its most common use - application on the agricultural land. This application is limited by legislative through the concentration limits of hazardous elements. For this reason, the potential ecotoxicity of sludge was evaluated. Ecotoxicological evaluation was performed using the contact bioassays. As the test organisms Eisenia foetida, Folsomia candida, Heterocypris incongruens a plant Lactuca sativa were selected. Sludge from wastewater treatment plants Brno - Modřice, Valtice, Mikulov and Lednice was tested. Samples of sewage sludge showed no ecotoxicity, while respecting the application amount established by the regulation. On the contrary, it can be concluded that soils enriched by sewage sludge show positive effect on soil biota.

Basides, the clients the services was inicated for are noticed here, too. It also concerns their state of health and social relations to the people around them and the surroundings. The data obtained from my own research are stated in the practical part. This research was carried out by a quntitative method with several techniques of a run interview and a secondary analysis of data in a set of some chosen patients living in the northern part of the Pilsen Region and agencies being situated in that area.
