Abstract The transformation of technogenic Cu and Zn compounds in technogenically transformed soils (Spolic Technosols) with high very concentrations metals formed at the site a natural tailings pond floodplain Seversky Donets River, main tributary Don River (Rostov oblast, Russia) has been studied. Technosols are compared to an unpolluted meadow-chernozemic soil (Fluvisol) outside impact zone....

The aim of the study was to investigate properties metallurgical sludge—waste from nickel production—on landfill a former plant in Sere?, Slovakia, relation technosols soil group. sludge is loose material which toxic industrial technological anthropogenic sediment an unnatural black colour originated crushing, washing, and leaching poor iron–nickel lateritic ore ammoniac solution other caustics...
