Few studies have examined the exposure of small streams (< 30 km2 catchment size) to agriculturally used pesticides, compared large rivers. A total 105 sites in 103 agricultural were investigated for 76 pesticides (insecticides, herbicides, fungicides) and 32 pesticide metabolites spring summer over two years (2018 2019) during dry weather rainfall using event-driven sampling. The median concentration was 0.18 µg/L, with 9 per sample on average (n = 815). This is significantly higher than...
Rain events may impact the chemical pollution burden in rivers. Forty-four small streams Germany were profiled during several rain for presence of 395 chemicals and five types mixture effects vitro bioassays (cytotoxicity; activation estrogen, aryl hydrocarbon, peroxisome proliferator-activated receptors; oxidative stress response). While these selected to cover a wide range agricultural impacts, addition expected pesticides, wastewater-derived typical street runoff detected. The...
The structure and biomass of aquatic invertebrate communities play a crucial role in the matter dynamics streams. However, is rarely quantified ecological assessments streams, little known about environmental anthropogenic factors that influence it. In this study, we aimed to identify are associated with through monitoring 25 streams across Germany. We identified invertebrates, assigned them taxonomic trait-based groups, using image-based analysis. found insecticide pressure generally...
Abstract Freshwater ecosystems subsidize riparian zones with high-quality nutrients via the emergence of aquatic insects. Spiders are dominant consumers these insect subsidies. However, little is known about variation consumption across spiders different hunting modes, habitat specializations, seasons, and systems. To explore this, we assembled a large stable isotope dataset (n > 1000) versus terrestrial sources six spider species over four points in time adjacent to lotic lentic system....
The progress in chemical analytics and understanding of pesticide dynamics surface waters allows establishing robust data on compounds with frequent exceedances quality standards. current chemical, temporal, spatial coverage the monitoring campaigns differs strongly between European countries. A questionnaire revealed differences strategies seven selected countries; Nordic countries prioritize temporal coverage, while others focus coverage. Chemical has increased, especially for non-polar...
The decomposition of allochthonous organic matter, such as leaves, is a crucial ecosystem process in low-order streams. Microbial communities, including fungi and bacteria, colonize material, break up large molecules, increase the nutritional value for macroinvertebrates. Environmental variables are known to affect microbial well macroinvertebrate communities alter their ability decompose matter. Studying relationship between environmental has mainly been realized using with drawbacks...
Biological indices aim to reflect the ecological quality of streams based on community´s species or trait composition. Accordingly, capability predict depends (i) knowledge association taxa traits with stressors and (ii) taxonomic quantitative resolution taxa. Generally speaking, a higher is associated better linkage between environmental condition biological response but also efforts costs. So far it unknown how affect assessment related pesticide effects when applying invertebrate-based...
