Evidence for chemical mixtures being a limiting factor for two impact endpoints. Left: area: Dutch surface waters; X-values derived from measured concentrations of chemicals in the Netherlands; Y-values are abundance data for an example taxon; dots: raw XY-data (nearly 6000 sites). Right: Area: European lowland rivers with a catchment area > 100 km2 (approx. 14,000 sites); X-values derived from predicted environmental concentrations of 24 priority substances [9], summarized as 95th percentile X-values within the ecological status classes; Y-values are WFD-ecological status classes (based on monitoring data)
