The distribution and behavior of certain of trace elements in sea water is greatly affected by both physical, chemical and hydrometeorological conditions that are showed in the scientific works of prof. Yu.A. Fedorov with coauthors (1999-2015). Due to the shallow waters last factor is one of the dominant, during the different wind situation changes significantly the dynamics of water masses and interaction in the system “water – suspended matter – bottom sediments”.Therefore, the study of the behavior of the total iron in the water of the sea at different wind situation is relevant. The content of dissolved iron forms migration in The Sea of Azov water (open area) varies from 0.017 to 0.21 mg /dm3 (mean 0.053 mg /dm3) and in Taganrog Bay from 0.035 to 0.58 mg /dm3 (mean 0.11 mg /dm3) and it is not depending on weather conditions.The reduction in the overall iron concentration in the direction of the Taganrog Bay → The Sea of Azov (open area) is observed on average more than twice. The dissolved iron content exceeding TLV levels and their frequency of occurrence in the estuary, respectively, were higher compared with The Sea of Azov (open area).There is an increase in the overall iron concentration in the water of the Azov Sea on average 1.5 times during the storm conditions, due to the destruction of the structure of the upper layer and resuspension of bottom sediments, intensifying the transition of iron compounds in the solution.

The aim of the work was to describe the first catch of Scophthalmus maeoticus (Pallas, 1814) in the Don River estuary (47°3′57′′N, 39°12′39′′E) and to analyze it in the context of salinity increasing in the Sea of Azov. The study was carried out using two turbot specimens caught on July 16, 2016, and on September 1, 2016, by a net with a mesh 55 mm. Assessment of the chalinic conditions of the Sea of Azov was carried out through annual monitoring at 3 hydrometeorological stations in Don River delta and in the eastern part of the Taganrog Bay. The article presents main meristic and plastic features of the turbots studied in comparison with published data. The dynamics of the salinity in the Sea of Azov and in the Taganrog Bay is analyzed. Find of the turbot in the estuary of the Don River is an evidence of ichthyocene transformation in response to salinity increasing (up to 12.5 ‰ in the Sea of Azov and up to 6 ‰ in the Taganrog Bay). The first catch of the turbot corresponds with trend of increasing of marine and brackish-water species share and with a decrease in the number of native semi-anadromous fish species.

The article analyzes the dynamics of changes in the content of petroleum products and a number of heavy metals (Fe, Cu, Zn, Pb, Cd) in the bottom sediments of the port of Temryuk in 2016–2020. Fluctuations in the concentrations of petroleum products in the soil from 88 to 413 mg/kg, iron – 8.4–41.0 mg/kg, copper – 13.6–116.0 mg/kg, zinc – 58.2–415.0 mg/kg, lead – 14.0–55.3 mg/kg, cadmium from less than 0.1 to 0.2 mg/kg were revealed. The geochemical features of the bottom sediments of the port of Temryuk relative to the sediments of the Sea of Azov are determined. Statistical processing of the obtained data made it possible to determine the correlation between the concentration of the substances in question in the soils of the studied water area.
