Theme I. Inventory, stratigraphy and conservation of mires and peatlands
Within an extended research project, a non-cultivated fen peatland site is ponded by treated waste water mixed with surface water, and the additional purification activity due to the anaerobic conditions and high carbon content of the peat is studied with respect to eco-toxicological substances. If a positive effect should be observed, a value-adding of the peatlands could be considered, (1) with respect to water quality improvement in surface waters, and (2) for biomass production. The special site conditions are affected by high sulfate concentrations in soil and groundwater. These conditions should be taken into the further investigations as possible constraints for an enhanced microbial decay.
