• Resumen

  • The Pb, Zn and Hg concentrations in the peat-bog samples of the Roñanzas record, that covers the last 8000 cal. BP, reveal a relationship with natural processes (climate, vulcanism) together with the atmospheric pollution linked to ancient minning, industrial activities, and agricultural development in northern Spain. There are metal enrichments along the peat profile probably related to the Roman Period, after 1700 AD and the Industrial Revolution and, in some cases, during the Visigod (Hg) and Islamic (Zn) Periods and Medieval Age (Pb, Zn). These processes are also observed in other European records, indicating that atmospheric pollution was produced globally, although with local particularities.
