Abstract
Analyses of fluorine concentrations in the waters of the Dead Sea and Lake Urmia yielded the values of 5.3 ± 0.1 and 10.5 ± 0.1 mg/L, which in terms of the mass of the salt residue gives 15.9 and 26.0 mg F per 1 kg of anhydrous salts. Fluorine concentration in the salt residue of water in the examined hypersaline water bodies is far less than that for the normal seawater (37.1 mg F/kg). Experimental data show that the waters of the Dead Sea and Lake Urmia are strongly undersaturated in CaF2, because of which spontaneous chemogenic precipitation of fluorite in them is impossible.
期刊介绍：
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
