Sledování obsahu fosforu ve vybraných profilech v povodí vodního toku Veverka

This diploma thesis deals with monitoring phosphorus content in watercourses of Veverka catchment area. The measurements were performed on six specific profiles during eleven-month period with intervals of 14 days. The analysis of samples was carried out at DALE laboratory using her equipment, namely the mineraliser -- Digital Reactor Block 200 (DRB 200), the spectrophotometer -- DR/4000. Simultaneously, pH, conductivity, temperature and dissolved oxygen levels were monitored in the field using portable device HQd HACH company. The water samples analysis indicates that Veverka catchment area is negatively affected by the increased concentrations of phosphorus. The main sources of phosporus are the waste-water treatments plants that causes water quality deterioration in catchment area. The agricultural activity has a marginal impact on water quality in terms of phosphorus
