The spatial distribution of heavy metals in abiotic components of aquatic ekosystems rivers depends primarily on landscape (natural) features of the area which is formed by runoff. Determining for the rivers and their areas under human influence becomes surface runoff from urban areas, wastewater and recycled water intake with feeding groundwater.The basic factors that influence the formation of the quality of the sediments in the river Seversky Donets and the accumulation of heavy metals were reviewed. Determined that a higher content of metals in the sediments have an average with a high content of silt and clay, which can be explained both by the chemical composition of the clay soil, and the ability to absorb himself in the metal from the aqueous phase.
