| Abstract: | The results of long-term studies of the conjugate distribution of methane (CH4) and sulfide sulfur (Ssulfide) concentrations in the bottom sediments of watercourses of the steppe zone of the European part of Russia are analyzed. In addition to CH4 and Ssulfide, Eh and pH values, humidity and density were determined in different sediment horizons; CH4, dry residue, and pH values were determined in water. Concentrations of CH4 in the watercourses vary from <0.1 to 2007.0 μL/L (median 24.3 μL/L), with the largest number of values (72%) in the range 10.1–100.0 μL/L. The concentrations of CH4 and Ssulfide in the bottom sediments of watercourses are quite high and vary, respectively, from <0.01 to 51.0 µg/g of wet sediment (median 1.35 µg/g) and from <0.001 to 4.50 mg/g of wet sediment (median 0.813 mg/g). Usually, the CH4 and Ssulfide concentrations increase from the surface layer to the subsurface horizons, and then decrease. The difference between the distributions of Ssulfide and CH4 is the more frequent occurrence of maximum concentrations of Ssulfide in less deep sediment horizons. Seasonal changes were recorded in the vertical distribution of CH4 and Ssulfide not only in terms of their concentrations, but also in the position of maximum and minimum values. There is a weak positive correlation between the concentrations of CH4 and Ssulfide, which indicates the synchronous formation of these gases in separate layers of sediments of the studied watercourses. The positive correlation established between the CH4 concentrations in water and 0–2 cm layer of bottom sediments indicates that the sediments are an important source of CH4 in water and its emission into the atmosphere.
