Abstract
Study of the concentration of chemical substances in the natural water of the Otrada Orthodox settlement in the Kirovsky district of Volgograd
Incoming article date: 07.08.2025The concentration of chemicals in a reservoir (Saltpetryanaya Balka) located near the Orthodox village of Otrada in the Kirovsky district of Volgograd has been studied in comparative comparison with the regulatory data of the MPC of chemicals in surface water bodies of cultural, household and fisheries significance.
The material for the study was natural water samples taken in the autumn season of 2024 in a lake near the village of Otrada in the Kirovsky district of Volgograd. Natural water samples were taken in accordance with GOST R 59024-2020 "Water". The analysis of chemicals was carried out on an EDX-8000 spectrometer. The data obtained (concentrations of chemicals in natural water samples) were compared in accordance with SanPiN 1.2.3685-21 and Order No. 296 of the Federal Agency for Fisheries dated May 26, 2025 and freshwater clarifications.
The data obtained indicate that the maximum permissible concentrations of chemicals were exceeded in the natural water of the Saltpetryanaya River as an object of cultural and domestic water use and indicates the mineral water of this reservoir and its possible use for recreational purposes as a balneological resource. There is an excess of the MPC values for copper by 10,000 times as the fishery value of the reservoir and indicates risks for representatives of the aquatic ecosystem. The use of this reservoir as an amateur fish farm may carry certain risks to human health when eating fish, which requires additional research and consultations with ichthyologists. The excess of copper by 10 times in comparison with freshwater reservoirs indicates the manifestation of a hidden deposit of copper ores in the vicinity of the Orthodox settlement "Otrada" (Volgograd).Keywords: dispersion, aerosols, surface density of particles, PM2.5, PM10, green infrastructure, natural pollution
