Mercury accumulation in peatbogs at Czech sites with contrasting pollution histories

► Hg accumulation rates (ARHg) in peat reflect differences in pollution history. ► At all the Czech sites, maxima in ARHg were between the 1950s and 1980s. ► The ARHg significantly correlated with the Pb accumulation rates. ► A slight increase in ARHg was observed in the most recent peat segments. ► High recent ARHg reflect emissions from intensive coal burning in Central Europe.
