Sažetak
Karašica River is the right tributary of the river Danube. Originating in Hungary (east of Pecs), it flows into the Danube near Batina. Since the 1990-ties industrial pollution in Croatia is in decline, the aim of our study was to analyse recent water quality parameters to determine whether water quality od Karašica River surface water has changed because of it. To that purpose, concentration of nitrogen and phosphorus compounds in Karašica River surface waters was analysed. Samples were taken once a month over the period of several years (2014– 2018). During analysed period concentration of total nitrogen was within the range of 1.00–5.60 mg/L, concentration of nitrites was 0.007–0.16 mg/L, while concentration of nitrates was 0.15– 5.42 mg/L, what is similar to the results obtained for the 2010-2015. period. Concentration of orthophosphates was within the range of 0.008–0.247 mg/L, and concentration of total phosphorus was 0.05–0.61 mg/L, what is higher compared to the previouslly analysed period. Analysed nutrients show a decrease in value during 2016-2018, with lowest measured value of nitrites of 0.007 mg/L, nitrates 0.15 mg/L, total nitrogen 1.00 mg/L, orthophosphates 0.008 mg/L, and total phosphorus of 0.06 mg/L. According to current regulations in Croatia, based on chemical parameters surface water quality of Karašica River can be characterized as moderate. Further continuous monitoring of water quality is necessary in order to improve reliability of water quality categorization.
