Abstract
Many-year (1981–2009) variations of hydrochemical and hydrobiological characteristics of the state of the aquatic environment in the Lower Volga are presented. The development and transformation of the structural organization of aquatic organism communities are considered against the background of a tendency toward the accumulation of key pollutants and the regional features of those processes are considered. The study has shown that the aquatic ecosystem of the Lower Volga functions with its ecological state disturbed because of the strengthening of ecological regress.
