Theme I. Inventory, stratigraphy and conservation of mires and peatlands
Trace metal concentrations (Fe, Ca, Mg, Al, Zn, Pb, Cd, Ba, Tl and As) in pore water has been studied seasonally in the extensively drained mire Bagno Bruch.
All the elements reveal higher concentrations in the pore water from upper layer. The maxima were observed in autumn when the mire was rewetted after a dry summer season. At that time the acidity dropped to the pH value of 3.0. The highest increase was detected for Ca, Mg, Zn, Cd, Ba and Tl. The concentration of Al was relatively stable during the study.
