Dissolved Inorganic Iodine in the Rogoznica Lake (Eastern Adriatic Coast)

The speciation of iodine in the water column of the Rogoznica Lake was studied during the period 1998-2000. This small, eutrophicated salt lake, where anoxic conditions mostly prevail only in the deeper layers, has undergone a complete anoxia in September 1997. Elevated concentrations of iodide in the deeper layers (up to 2.4 μ mol/L), and iodate in the oxic part of the water column (up to 0.53 μ mol/L), were maintained for almost two years. The biogeochemical renewal processes that affect the concentration of both iodate and iodide within the water column seem to be slow in comparison to those that govern the speciation of iodine.
