Sampling and analisys of sediments from Smolenská water reservoir basin

Popis výsledku v původním jazyce

The aim of this paper is to evaluate the ecotoxicity of sediment from Malonínský brook, sedimentation reservoir and Smolenská water reservoir, which are located on this creek. The second objective is to compare the concentration of the risk elements contained in the sediment from the Smolensk water reservoir with the limit values set out in the Decree No. 257/2009 Coll., As amended. A methodology for the collection and evaluation of sediment samples, which is based on valid legislation and valid CSS standards, was developed. The area of interest was divided into 4 parts. For each part of the territory, one single mixed sample was created. In the laboratory of the Department of Applied and Landscape Ecology, an ecotoxicity test was carried out by the method of Inhibition of Growth of Root of Higher Plants according to CSS EN ISO 11269-1. The chemical analysis of the risk elements was processed only for sediment from the Smolenská water reservoir. After comparing the measured concentrations of the individual indicators for the mixed sample from the Smolenská water reservoir, it is clear that the limit values given in Annex 1 to Decree No. 257/2009 Coll. are not exceeded. From the results of the ecotoxicity test, it can be seen that the mixed sample of sediment collected from the Malonínský brook in part 4 does not reach the required values according to Decree No. 257/2009 Coll. and is ecotoxic. Mixed sediment samples from part 2 and part 3 are not ecotoxic, but the test results are closer to the limit. The sediment from part 1 - above the Smolenská reservoir is not ecotoxic. It is not advisable to build the pond sediment as a waste, but after meeting the requirements for the concentration values of the risk elements as for the fertilizer. It is necessary to mix sediment before placed on farmland. The results show that for the sediment from the site, the ratio of substrate mixing to the sample is 3:1, i.e. 75% of the substrate and 25% of the sediment volume.
