The Space and Time Variations of Water Quality and Water Pollution Dynamics in the Oka Basin

Аннотация

The space–time variations in the Oka basin water chemistry have been considered. The specific features in the river water and groundwater pollution along the Oka channel and its main tributaries have been determined. The distribution of the main pollutants and their sources along the river areas has been identified. Schematic maps of the hydrochemical flow and time variations in the main pollutants have been compiled. The main types of river aquatic organisms have been characterized, and their dynamics has been described depending on the level of river water pollution.
