The quality of the water and bottom sediments of the Rybinsk Reservoir, on the adjacent territory of which the Cherepovetskiy Metallurgical Plant PJSC “Severstal” is located, which has an adverse effect on the state of the water body is investigated. The pollution of water and bottom sediments by the metallurgical plant in the northern part of the Rybinsk reservoir was assessed in connection with the planned construction of a pulp and paper mill (PPM) at the site of the study.

An approach is proposed for ranking the quality of freshwater ecosystems by the state of bivalve mollusks living in them. Cardioactivity indicators and accumulation of metals in the tissues of the mollusks from various waters of the eastern part of the Gulf of Finland and the Rybinsk Reservoir were used to characterize the ecosystems, and an original hyperosmotic test was used to analyze the functional state of the mollusks.

The paper presents the results on the content of heavy metals in the bottom sediments of shallow areas of the Sheksninsky spur and the correlation dependences on the content of heavy metals. Significant differences in the content of heavy metals on different banks of the Sheksninsky spur were found only for lead (p=0.042). The matrices of paired correlations were constructed, the analysis of which showed that a greater number of dependencies with heavy metals were found on the right bank. The sorption of mercury by organic matter plays a greater role than the sorption of other elements, the correlation is significant r=0.70. Single exceedances of maximum permissible concentrations (MPC) of lead and copper in bottom sediments of the right bank were detected. Exceedances of element clarks determined for the earth crust were observed for lead, zinc, copper for bottom sediments of the right bank. A decreasing series of distribution of heavy metal concentrations in bottom sediments of the Sheksninsky spur was determined.
