German Monitoring of Plant Protection Products in Small Streams

The mostly insufficient ecological status of surface waters is most often explained by habitat degradation and excessive nutrient input. But what role do plant protection products play in this context? In the Monitoring of Small Streams (Kleingewässermonitoring - KgM), the influence of plant protection products on small and medium-sized streams and resulting ecological impacts are investigated on a globally unique scale.

The resulting scientific study "Pesticides Are the Dominant Stressors for Vulnerable Insects in Lowland Streams" shows the high relevance of pesticides for the ecological status of these waters. In addition, for the first time, weak points in the current risk assessment of pesticides could be identified in such a concrete and evidence-based manner, and field-based threshold values for pesticide active substances could be derived.
