Abstract

A study was conducted from year 2012 to 2015 to monitor the pathways of runoff flow components from the landscape in the Swist river basin, near Bonn (Germany). For this purpose, an innovative strategy was developed to collect samples from surface and subsurface runoff under different land use directly before entering the Swist river system. Numerous locally applied pesticides, some frequently used pharmaceuticals, industrial chemicals and flame retardants were detected. The monitoring system used in the project is able to collect realistic entries into rivers stemming from runoff components for different land use areas.
