Abstract
Today, the quality of water in the world is changing significantly due to the increasing human impact on the environment. The paper presents an analysis of the surface water quality of the Danube river at five hydrological stations in Serbia for 2018. Using the relevant method - the water quality index, in this case, the Serbian water quality index (SWQI) ten physico-chemical and microbiological parameters (oxygen saturation, Five-Day Biochemical Oxygen Demand or BOD5, ammonium ion concentration, pH value, water) were analyzed Total Nitrogen or WTN, Total Suspended Solids or TSS, orthophosphate concentration, electrical conductivity, temperature and fecal coliform bacteria presence in water). The values obtained are classified in 5 classes depending on the water quality. The lowest (good) water quality was recorded on the Zemun - Smederevo river course, while in Bezdan, Novi Sad and Radujevac, the average annual water quality is very good.
