COMPARISON OF SOIL CONTAMINATION AT THE SELECTED EUROPEAN COPPER MINES

This article reports the results of a study concerning contamination dump-fields by potentially toxic elements at five abandoned copper mines: ?ubietová, Špania Dolina (Slovakia), Libiola, Caporciano (Italy) and São Domingos (Portugal). paper offers an updated description soil individual deposits indicates possible solution derived environmental problems. Contamination technosoils PTEs shows irregular spatial distribution Fe, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Sb Pb. Contents often exceed both national EU law limits. Whereas risk is limited, Libiola it seems to be very heavy. The technosoil (slag) not well aerated colloids have (except for Dolina) negative surface charge, so they are suitable sorption. main in mining area Sao district long time formation acid mine drainage water high As Pb contents. release components may limited phytostabilization immobilization metals, admixtures into technosoil/slag. situation compromised as area.
