Sažetak
Enrichment of surface water with nutrients causes intensive algal growth and higher plants growth, which leads to imbalances in the ecosystem and Water Quality Impairment. Increased concentrations of nutrients (total phosphorus, nitrates) lead to rapid assimilation of inorganic into organic matter in the process of photosynthesis, resulting in increased algal biomass (algal blooms) and increased total production and concentration of organic matter in aquatic ecosystems. In accordance with the aims of the Naturavita project, the ecological status of surface waters was monitored at 19 locations in the period from July 2020 to the end of June 2021 in the Kopački Rit nature park. Regarding its basic physico – chemical and chemical parameters, the assessment of the ecological status of surface water bodies is defined according to the limit values of the 50th percentile, and in accordance with the Decree on the water quality standard (OG 96/2019). The values of the 50th percentile for the total phosphorus ranged from 0.02 to 0.10 mg P/l, and for nitrates from 0.11 to 1.35 mg N/l. Out of 19 locations based on the 50th percentile, 17 locations were rated as very good and 2 locations as good ecological status according to nitrates and according to values for total phosphorus, 14 locations are in very good and 5 locations are in good ecological condition.
