Combined chemical and phytostabilisation

Combined chemical and phytostabilisation of metal contaminated soil and mine waste

Viktória Feigl

The innovative technology of combined chemical and phytostabilisation was applied to the site of 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 Zn, Pb, Cd, Cu and As, due to former mining. To select the most suitable combination of chemical stabilisers and plants several experiments were performed from laboratory to field scale:  laboratory microcosm, pilot lysimeters and field plots. In the microcosms we tested 12 chemical stabilisers, while in lysimeters and field experiments we applied also plants. The most promising stabilising agents were fly ash and lime which were applied on the field.
