Lay Summary (Englisch)

Lay summary
This project is part of the Prodoc module “Scientific concepts for the sustainable management of mid-sized lakes in the 21st century”. With two PhD theses, the project will focus on the origin and the fate of micropollutants in the catchment of Lake Geneva. It will be based on three small, but typical catchments in the Lausanne area, comprising an (i) agricultural area with different cultures, and an important urban area, which is subdivided in (ii) combined sewer systems ending up in a waste water treatment plant and a (iii) separated sewer system, where the stormwater runoff is discharged in local rivers or directly into the lake. For the agricultural area, emphasis will be put on pesticide pollution and for the urban area on pharmaceuticals and urban-specific biocide pollution. All these substances are of high relevance as they can have deleterious effects on the aquatic ecosystem. Some of them have been already measured in the center of the lake. One of the PhD candidates will focus his work on agricultural pollution by conducting a qualitative study on the main characteristics of this contamination. He will identify the origin of the pesticides depending on agricultural practices, and their behavior as a function of soil and sediment types (organic matter and clay minerals) and transport in soil and river water (dissolved and as particles). The other PhD candidate will concentrate his work on the urban environment and will be responsible for quantifying and modeling the flows and micropollutant loads of both the agricultural and urban part of the studied catchments. Both students will use up-to-date sampling devices, modeling software and analytical instruments in the field of humic matter characterization, clay identification, isotopic and micropollutant analysis.
