These simulation results demonstrate that our conceptual framework of the processes involved in the loss of pesticides from their place of application to adjacent
surface waters is able to explain observed pesticide patterns in a qualitative manner,
forming the fundamental basis for future mitigation strategies.
Acknowledgements We are indebted to the Deutsche Forschungsgemeinschaft (DFG) for their
generous funding of the Uplands Program (SFB 564). We would like to thank Ludger Herrmann
and Carsten Marohn for their helpful comments, Gary Morrison for reading through the English,
and Peter Elstner for helping with the layout.
