Studium funkce rybníku Nezmar

Abstract

The thesis deals with the study of Nezmar pond which is situated in Dolní Benešov in Moravskoslezský Region. The work is focused on the evaluation of the water quality parameters of three types of water samples – input water, output water and pond water. These samples were collected monthly and analyzed in situ, namely measurements of temperature, pH, conductivity and oxygen concentration. The parameters as dissolved solids, suspended solids, form of nitrogen, forms of phosphorus, etc. were analyzed in the laboratory of Institute of Environmental Engineering. The results of all samples were evaluated graphically and the results were compared with the optimum conditions for life of fish, according to Government Order of the Czech Republic 71/2003 Coll. and according to Government of the Czech Republic 401/20156 Coll. Next, dependencies among certain parameters were evaluated and the concentrations of metals in fish were detected.
