REXPO - Realistic Exposition szenarios of surface waters

The aim of the project was to quantify the biocide/pesticide losses to surface waters originating from urban and agricultural areas focusing on rain-driven contamination events. On the one hand, the project consisted of an intensive field campaign (2007). On the other hand, a main effort went into the modeling of the substance fluxes to be able to transfer the findings to other regions.
