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.
