Abstract Despite considerable progress in our predictive capacity for the response of different trophic levels to chemical stressors, generalizable relations between stressors and ecosystem functions are lacking. We addressed this knowledge gap by conducting a meta-analysis (153 studies; 350 observations) on responses freshwater (community respiration, organic matter decomposition, nutrient cycling, photosynthesis, primary production) under controlled conditions (laboratory or outdoor mesocosms) pesticides, pharmaceuticals, metals. identified monotonic dose-response relationships standardized concentrations, terms toxic units, selected use groups decomposition decomposer-detritivore-systems as well photosynthesis algae macrophytes. By contrast, consistent were not found other functions, such microbial decomposers alone production studied. Importantly, shape direction here match those reported field-based studies, indicating decrease functioning stress increases, strengthening ecological relevance findings. Finally, we disconnect regulatory quality targets outcomes, highlighting need re-evaluate risk assessment approaches if they supposed be ecologically meaningful protective functions.

Abstract Exposure to synthetic chemicals, such as pesticides and pharmaceuticals, affects freshwater communities at broad spatial scales. This risk is commonly managed in a prospective environmental assessment (ERA). Relying on generic methods, few standard test organisms, safety factors account for uncertainty, ERA determines concentrations that are assumed pose low risks ecosystems. Currently, this procedure neglects potential variation assemblage sensitivity among ecosystem types recommends single low-risk concentration each compound. Whether systematic differences exist or their size, currently unknown. Elucidating patterns chemicals could therefore enhance precision narrow fundamental knowledge gap ecology, the Hutchinsonian shortfall. We analyzed whether taxonomic turnover between field-sampled macroinvertebrate assemblages of different river across Europe results copper imidacloprid. used an extensive database compositions throughout employed hierarchical species distribution model predict would be harmful 5% taxa (HC 5 ) assemblage. Predicted $$H{C}_{5}$$ H C 5 values varied over several orders magnitude. However, within 95% highest density intervals remained one order Differences were minor imidacloprid only slightly higher copper. The largest difference river-type-specific median was factor 3.1. level below recommended by European Food Safety Authority captured current plant protection products. conclude composition translate into relatively small toward evaluated scale. bioavailability multi-stressor context not might exacerbate ecological effects real-world
