IRON GEOCHEMISTRY IN THE MIUS RIVER - MIUS ESTUARY - TAGANROG BAY OF THE SEA OF AZOV SYSTEM
The results of studying the distribution and behavior of gross iron content, its dissolved and suspended migration forms, pH values and salinity (salinity) along the Mius river - Mius estuary - Taganrog Bay of the sea of Azov transect are presented. A significant increase in the concentrations of gross iron, as well as its dissolved and suspended forms during the transition from river waters to the waters of the Miussky estuary, with a subsequent decrease at the outlet of the estuary and the Taganrog Bay. It is shown that the predominant form of iron migration in the studied system is the weighted form (over 84% of the gross). In comparison with retrospective data, there is currently an increase in mineralization in the Mius river and salinity in the Mius estuary and Taganrog Bay, while iron concentrations tend to decrease over time.
