Annotation:  The concept of genotoxicity (genetic activity) includes any changes in the course of genetic processes under the influence of environmental factors. Assessment of the genetic activity of the latter is carried out through genetic test systems that are created on the basis of indicator species and genetic criteria for the damaging effects of biosystems at different levels their organization. The development of this approach in bioindication and biomonitoring, in particular, the state of the aquatic environment allows the assessment of genetic the activity of components of pollution of anthropogenic nature and make predictions regarding their long-term effects. The research material was samples of water, bottom soil, and algae in individual components of the water and coastal ecosystems of the Voronezh reservoir. Genotoxic compounds were found in all studied components of aquatic and near-water ecosystems of the Voronezh reservoir. The most active xenobiotic accumulators in the aquatic environment are algae, and in the terrestrial – soil.
