| Popis: | This article summarizes the original results of a study of fluorine levels in the water of Kuyalnik estuary and its watercourses for the period 2005-2013. We estimated dynamics of annual and seasonal changes of the fluorine concentration in Kuyalnik estuary and main waterways of income. It is shown that the interannual fluctuations in the concentrations of fluoride in the estuary is mainly determined by its hydrological regime, of irregular economic activities on the territory of the catchment area, rainfall run-off from agricultural land. The distribution of fluoride in the water area of Kuyalnik estuary are presented on maps. We found a significant correlations between fluoride and pH in water and organic matter in sediments of the Kuyalnik estuary. A strong correlation was found between the concentration of fluoride and the F:Ca, F:Mg ratio in waters of the estuary. Obtained data indicate the determining role of acidity in adsorption immobilization of fluorine. |
