ROLE OF CHEMICAL SUBSTANCES INFLOW IN ANTHROPOGENIC TRANSFORMATION OF RIVER VOLGA MOUTH AREA
Estimation of chemical substances inflow at the outlet of the river Volga was carried out. It was made based on of long-term hydrochemical data provided by Government Agency of Environmental Monitoring and Control. Biogenic compound accumulation and built-up of pollutants in the mouth area of the river was registered. Inflow of chloride, nitrogen (ammonium-and nitrite-), phenols and petroleum products was shown to be less than that of sulphates and iron.
