Correlating the concentration of mobile manganese with redox- and acid–base properties in sediment column of the Mozhaisk Reservoir in the period of its formation (1970-1975)

Аннотация

Data of 1970-1971 and 1974-1975 for six layers of the Mozhaisk Reservoir were used to analyze the within-year relationships between Mn concentration and silt Eh and pH. The character of these relationships is explained. For the first time, a critical Eh zone, where Mn concentration abruptly changes, was identified. The redox processes involving Mn were shown to gradually stabilize over time.
