Environmental pollution in large industrialized cities has become an urgent global problem. On the territory of the Russian Federation, a tense ecological situation is developing in almost all cities with a population of over one million and in large administrative centers. The creation of a quality urban environment is a national priority, a complex and financially costly task, the solution of which cannot be postponed any longer. The main sources of problems in the territories occupied by cities lie in the concentration of production capacities, the steady growth of the population, and as a result, the amount of transport. Due to production, industrial cities concentrate substances of natural and man-made origin forming local and even regional geochemical anomalies in various landscapes. Among all the interrelated components, a special place belongs to the depositing (accumulating) media–soils and bottom sediments. Based on the results of geochemical studies of 2018–2020, the indicators of the quality of the soils of Voronezh were determined, the levels of the content of pollutants of I-III hazard classes in the soils of urban and peripheral areas of Voronezh (benzo(a)pyrene and heavy metals) were established. The authors provide an assessment of the accumulation of pollutants in the bottom sediments of the Voronezh water reservoir, which is located on the territory of the urban district.

Aim. Assessment by nitrification index values of the level of trophicity and toxicity for aquatic organisms in the waters of a small watercourse in an urbanized area by the content of nutrients in the water and its selfcleaning ability.Materials and Methods. The concentration of compounds of nutrients in the waters of the river was determined using the "Kapel 104T." system of capillary electrophoresis. Water was sampled for analysis according to GOST R 51592- 2000. The water content of readily oxidized organic compounds was assessed by the magnitude of permanganate oxidizability (PND F 14.1; 2.4.154-99) and difficultly oxidized compounds by the magnitude of the chemical oxygen consumption (RD 52.24.421-2012). Assessment of the water trophic level was evaluated by measuring the content of various forms of mineral nitrogen and mineral phosphorus. The aggregation index characterizing the toxicity of various forms of mineral nitrogen to aquatic organisms was calculated by their ratio to MPC for fishery reservoirs. The nitrifying ability of river waters was estimated by the value of the nitrification index (Initr.), calculated by the ratio of the concentration of nitrogen of nitrates in water to the sum of the concentrations of various forms of mineral nitrogen and the self-cleaning ability by the values of the nitrification index.Results. In terms of the aggregation index, water at all sampling points was found to be toxic. The river ecosystem is characterized by a weak ability to cleanse itself and a weak nitrifying ability, which is associated with the influence of numerous cyanotoxins on the microbiocenosis of the watercourse and filtration organisms.Conclusion. It was shown that the most sensitive indicator of trophicity of river waters is the concentration of the mineral phosphorus. Through measuring the ratio of the concentrations of mineral nitrogen to mineral phosphorus, it was established that blue-green algae (cyanobacteria), producers of cyanotoxins, dominate in the phytoplankton of the river in all the points studied.
