In the present study, in laboratory conditions, a series of experiments were conducted to study the immobilizing ability of peats of Electrochemical Plant (Zelenogorsk, Krasnoyarsk Krai, Russia). It has been found that the studied sorbents have a significant sorption capacity and a reliable conservation ability towards uranium ions that prevent its spread outside the sludge storage. For quantitative characterization and calculation of sorption coefficients, laboratory experiments were conducted for three samples o...

The paper focused on the formation mechanisms of the geochemical soil background for a wide range of elements. Three areas in Siberia of the coal mining spoils were investigated. The spoils were recultivated 30 years ago by applying a homogenous layer of loamy bedrock as a potentially fertile substrate and then left for spontaneous revegetation. The assessment was conducted using bulk concentrations of the elements. Since there is no excess in concentrations of heavy metals and radionuclides in the recultivated sp...
