Fig. 3From: Evidence for antifouling biocides as one of the limiting factors for the recovery of macrophyte communities in lakes of Schleswig-HolsteinBarplot of TUs determined at different lakes and sampling points for a macrophytes and b crustaceans. Horizontal lines represent the thresholds for acute (0.1 TUs for both organisms) and chronic toxic effects (0.02 TUs for macrophytes and 0.001 TUs for invertebrates). Colourized pollutants account for ~ 90% of the calculated TUsBack to article page
