Ecological evaluation of streams in protected area Křivoklátsko in Directive 2000/60/ES

This thesis deals with the monitoring of water quality and aquatic sediments analysis in the protected area Křivoklátsko. Monitoring was carried out at 16 locations and there were determined 14 physico-chemical parameters . Sediment samples were collected once for the whole period at 14 locations in which was determine the content of metals. In each sediment sample there was analyzed content of selected metals. The results of analysis, water and sediment samples were evaluated according to the Directives and regulations giving limits for water and sediment. Due to the Czech Republic is a member state of the European Union, the state was also evaluated according to Water Framework Directive. Theoretical part of thesis decribes characteristics of metals, their forms in water and soils. This section also contain some informations about water framework directive 2000/60/EC as a great step in a water policy. Moreover there is a short history about development water quality in the Czech Republic. Experimental section contains standards for determining water quality, but indicating in particular the processing of sediment samples from sampling to determine concentrations. The following chapter deals with the evaluation of the results given by legislation - for water to the CSN 75 7221 and Regulation..
