RECLAMATION POTENTIAL OF ROBINIA PSEUDOACACIA L. ON MINING ROCK WITHIN STEPPE ZONE OF UKRAINE

Abstract

Western Donbass is a powerful coal-mining region in the Steppe zone of Ukraine. In this region, large areas are damaged by coal mining. The mine rocks spread all over the coal district of Dnipropetrovsk region often contain toxic inorganic contaminants. In this regard using mine rocks for biological reclamation is nowadays an important environmental issue. Tree species can accumulate heavy metals from technosoils during the whole year and transfer these elements together with other nutrients to aboveground phytomass through the vegetation period.
