Sažetak

This study examines the impact of slow de-stratification on the inorganic iodine, sulphur and nutrient systems in the eutrophic anchialine pond Zmajevo oko (Rogoznica Lake). The observed changes in both the vertical distribution and the speciation of the investigated variables were pronounced. Although the redox conditions formed immediately after the de-stratification were oxic to hypoxic, iodate was reduced to iodide.
