Reduced forms of sulfur in the brine of Saline–Soda Lake Doroninskoe, eastern Transbaikal Region

Abstract

Contents of inorganic reduced forms of sulfur were determined in the oxygen-bearing waters of saline-soda Lake Doroninskoe. The vertical and annual distributions of individual species and total reduced sulfur have been studied. It was found that oxic zone ubiquitously contains reduced sulfur with contents: HS− 0.002–3.86 mg/l, S0 0.002–0.129 mg/l, S0; 4+ 0.014–9.19 mg/l. Oxygen concentrations varied from 0 to 6.8 mg/l. These sulfur compounds show unsystematic vertical distribution, which during transitional season is controlled by intensity of bacterial processes.
