Abstract

The article presents the results of hydrochemical survey in the Pinega State Nature Reserve in 2019‒2020 on the main nutrients, dissolved oxygen, salinity, and pH, as well as concentrations of oil products in water and bottom sediments. The results showed that the concentrations of biogenic elements and oil products were much lower than the maximum allowable concentrations.
