A fundamental prerequisite of the efficient water quality improvement is the presence of redox potential gradients (connected with the aeration of the system) inside the vegetation bed. Redox properties of a constructed wetland were tested in three longitudinal transects, crossing the vegetation bed from the inflow zone to the outflow using diverse indicators (e.g., Fe-III/Fe-II, SO42-/S2-). Approximately 10-25% of iron was reoxidized in samples taken 10 m from the inflow zone in 2006. Redox processes of iron in artificial (constructed wetland) and natural (peat hog) ecosystems were compared. The peat bog was characterized with higher percentages of Fell (usually ca. 90-100%). Thus, the aeration of the peat land was lower in comparison with the constructed wetland. The constructed wetland efficiently reduced Sulfates (average concentrations of 44.7 and 11.2 mg/l at the inflow and the Outflow, resp., in 2007). Organics,"@en . "4"^^ . . "000264787700008" . .
