Improving the 210Pb-chronology of Pb deposition in peat cores from Chao de Lamoso (NW Spain)

► Peat cores collected in NW Spain were used to reconstruct recent Pb deposition. ► Applicability of 210Pb-dating models (CRS) in bogs is discussed based on PCA results. ► Results showed that ~ 20% of the 210Pb flux was related to anthropogenic metal pollution. ► Geochemical analysis of bogs is useful to interpret the historical peat record.
