Impact of ancient iron smelting wastes on current soils: Legacy contamination, environmental availability and fractionation of metals.

Past and present metallurgical activity is the origin of the metallic contamination of some current soils. The purpose of this research is to assess the environmental risk of ancient Fe smelting wastes to the terrestrial compartment. For this purpose, two study sites were investigated in Bourgogne-Franche Comté (France).
