Antimony (Sb) exists in fossil fuels, especially in coal. Fossil fuel combustion is likely the largest source of anthropogenic Sb emissions to the atmosphere. Abundant in sulfide minerals and co-occurring with heavy metals, Sb emissions likely result from the mining and metallurgy of nonferrous metals, especially Pb, Cu, and Zn.
