| Abstract | Weighable lysimeter with groundwater regulation were used to quantify groundwater recharge from a floodplain site of the Elbe River. The lysimeter experiments are linked with in situ investigations carried out at a semi-automated field research station situated in the floodplain area. Here, more process orientated investigation of possible migration of heavy metals and As by means of suction cups and redox probes, installed into a flood channel were carried out. The investigations revealed a substantial mobilization of As and partly Cd, Cu and Ni that exceeded the precaution values for the path soil - groundwater. While Cd, Cu and Zn were leached or immobilized, the concentration pattern of Co and Mo coincided with the increase of Mn. The release of these elements was assumed to be due to the dissolution of Mn and Fe oxides and hydroxides at lower redox potentials as dominating process. Also As showed a significant response to the dissolution of the oxides. Ni and Cr were characterized by a continuously increasing release peaking after the end of the inundation. Results of in-situ redox potential measurement indicated a delay of 4-5 weeks for the release of the redox-sensitive metals. |
