Sažetak
Freshwater chemistry is quite variable and depends on many factors, such as the type and hydrological characteristics of the water body, the geological back-ground, the type of climate, and the biological and physico-chemical processes that take place in it. Plitvice Lakes National Park is a unique and complex freshwater barrage lakes system characterized by the deposition of carbonates in the form of tufa and fine-grained lake sediment. Analysis of long-term monitoring data of physico-chemical parameters from seventeen sites on the longitudinal profile of the water system of Plitvice Lakes, the main characteristics and spatial and temporal variations of water chemistry were determined. The waters of Plitvice Lakes are oligotrophic with low content of nutrients and dissolved organic matter, dissolved oxygen concentrations around saturation and relatively high values of hardness and alkalinity. The karst springs are characterized by relatively constant values of all monitored parameters without seasonal variations, while some seasonal dynamics were observed at the tributaries depending on air temperature and catchment characteristics. The water chemistry of the lotic biotopes at the tufa barriers and the Korana River differs significantly from the springs and tributaries. Temporal and spatial variations are the result of seasonal changes in air temperature, biological processes, hydrodynamics of the barrage lake system, and intensive deposition of tufa and lake sediment in the lake system.
