Abstract
Purpose: analysis of the influence of atmospheric precipitation and air temperature on the formation of geochemical background of water bodies in the zone of collector canals of the Bagaevskaya irrigation system. Materials and Methods: analysis of the report on atmospheric precipitation and chemical measurements of waste and natural water samples from collector canals for the period 2014–2020; assessment of long-term (1900–2020) dynamics of the average annual temperature of atmospheric air. Results. The assessment of the chemical composition of water intake waters was carried out by the sum of the main salt-forming ions at the confluence of collector canals into water bodies, in the background and control sections. Samples of waste and natural water were analyzed separately for the sulfates, chlorides, hydrocarbons content indicators. A relationship between the Total Dissolved Solids and the precipitation amount 30 days before the date of sampling (inclusive) was revealed. The trend of the value of the average annual temperature of atmospheric air is determined in respect to the territory of the Lower Don. Conclusions. The concentration of substances in the water inputs (the Podpolnaya and Western Manych rivers) at the outlet of drainage and waste waters from the BG-MS-6 and BG-MS-10 canals does not exceed the concentration in the background section, which indicates a natural (conditionally-natural) background of water bodies. The dynamics of mineralization indicates that the ionic composition of water bodies within the Bagaevskaya irrigation system is formed due to the input of salts by surface runoff into the composition of atmospheric moisture, as well as in the process of groundwater feed. On a more global scale (on the whole territory of the Lower Don), the geochemical background of small water bodies is influenced by a gradual increase in the average annual air temperature.
