Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Oct 01, 2019· 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 .
