Změny kvality vody v toku vlivem přítoku odpadů z koňské farmy
Khainová, Barbora
The bachelor thesis focuses on monitoring changes in the quality of the Všeminka stream due to the impact of waste inflow from the Všemina Horse Ranch. A total of six sampling sites were identified and located along the length of the stream so that the first location was above the ranch and the last was below the Všemina reservoir. Sampling was conducted four times over a thirteen-month period during the growing season. During the sampling events, pH, dissolved oxygen concentration, conductivity, water temperature, and, for the reservoir, water transparency was determined on site. The samples were immediately taken for evaluation to the laboratory of the Department of Fisheries and Hydrobiology at Mendel University in Brno. Physico-chemical parameters such as total nitrogen, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, total phosphorus, orthophosphates, total iron, chemical oxygen demand by dichromate, biochemical oxygen demand-five-day, acid neutralization capacity, calcium and chloride were selected for subsequent analysis. The objective was to determine if the ranch has an effect on water quality in the stream or the Všemina Reservoir. The resulting values from the laboratory analysis were evaluated according to the standard CSN 75 7221 used to classify the quality of surface waters as well as according to Government Regulation 401/2015, whether the quality of the water meets the requirements for general water use, for salmon and carp waters. Furthermore, it was compared with similar research works on the given topic of the influence of horse breeding on water quality.
