Sažetak
National Park Plitvice lakes presents one of the most beautiful karst complexes in the world. Its waters are supersaturated with dissolved calcium carbonate (calcite) which is released and deposited in the form of tiny crystals as a result of water splashing at tufa barriers. Sulphates, present in the particulate matter (PM), can be deposited on the surface of the calcite. In the air, sulphate particles are formed by the oxidation of SO2 in a series of chemical reactions [1]. Fast oxidation of SO2 in nature can also take place on the surface of calcite in the presence of ozone and is significantly enhanced by high humidity [1, 2]. The resulting sulfates can destroy the surface of calcite and indirectly influence the composition and quality of water. Hourly concentrations of ozone, PM10 and PM2.5 at the monitoring station Plitvice Lakes in the period from 2012 till 2014 are presented. Measured concentrations of PM were highest during the winter period, while the highest ozone concentrations were measured during the spring, but were also higher in winter. Following work shall investigate changes of water composition at tufa barriers of Plitvica lakes in regard to the concentration of sulphate particles and ozone.
