ABSTRACT
ABSTRACT: Innovative technology of combined chemical and phytostabilisation was applied to a site at Gyöngyösoroszi (Hungary) under the Hungarian research and development project MOKKA (Innovative Decision Support Tools for Risk Based Environmental Management) and BANYAREM, and the EU Life project Difplomine. The area is heavily polluted with toxic metals, such as Zinc, Lead, Cadmium, Copper and Arsenic due to former mining. Point and diffuse sources have been identified and prioritised according to risk. To select the most suitable combination of chemical stabilisers and plants for the moderately polluted mine waste and contaminated soil several experiments were performed at different scales-laboratory microcosms, pilot lysimeters and field plots. Twelve chemical stabilisers were tested in the microcosms while plants were used in lysimeters and field experiments. The most promising stabilising agents were fly ash and lime applied in the field.
