Description: Das Projekt "Natural and anthropogenic aerosols from ice and sediment Alpine records: Climatic, stratigraphic, and environmental implications." wird vom Umweltbundesamt gefördert und von Universite de Geneve, Institut F.-A. Forel durchgeführt. This follow-up project aims to reconstruct natural (climatic) and anthropogenic-induced hydrological changes and to provide new insights on the anthropogenic pollutants emitted in European environment over the last centuries, by focusing on: (1) The largest freshwater lake of Western Europe (Lake Geneva) and especially on industrial (trace metals) and microbial (pathogenic bacterial activity and resistance to antibiotic) pollution in the Vidy Bay; where are discharges the treated wastewaters of Lausanne since 50 years. (2) A drinking reservoir (Lake Brêt) in order to evaluate the impacts of agricultural activities and sewage emissions on the pollution of drinking water in Switzerland over the last century. Results demonstrate a slight enrichment in anthropogenic heavy metal since the 1950s but an additional (agricultural) source of copper during the last decade. In the absence of industries in the catchment, the records of DDT and PCBs highlight the long-range atmospheric transport of POPs that contaminated rural water resources via catchment runoff. (3) Human impact on the deposition of anthropogenic and natural trace element fluxes were measured in sediment cores from Lake Biel and from two upstream lakes (Lake Brienz and Lake Thun), all three connected by the Aare River. Results indicate that that the construction of sediment-trapping reservoirs significantly decreased regional riverine sediment discharge. Radiometric dating of the sediment core from Lake Biel furthermore identified hydrological releases of anthropogenic radionuclides from the nuclear reactor of Mühleberg located at ca.15 km from Lake Biel. Five publications (in refereed journals) directly resulting from this follow-up proposal are in process of publication.
