Elba Island was a hotspot of iron mining and smelting in Italy since Etruscan times (6th century BCE). Whereas the environmental burden of modern (base) metal mining in Tuscany is well studied, the impact of both ancient iron mining and smelting on soils in the region is poorly understood. Therefore, we took soil samples from an ancient smelting site and adjacent areas to evaluate the release
