Summary: In this study, the ecotoxicity of copper oxide nanoparticles (CONPs) on Duttaphrynus melanostictus tadpoles was assessed by measuring multiple biomarkers including bioaccumulation, antioxidants, biochemical, haematological, immunological and oxidative stress biomarkers. The results showed significant increases in copper ion bioaccumulation, oxidative stress and biochemical biomarkers in the blood serum of CONPs-exposed tadpoles compared to control tadpoles. Additionally, CONPs-exposed tadpoles exhibited decreases in antioxidants and immunological indices of blood serum. The study concluded that the ecotoxicity of CONPs is associated with the production of reactive oxygen species, which cause oxidative stress in tadpoles.

Summary: The study successfully characterized pesticide pollution in 13 streams in Western Kenya using minimal adaptations of the SPEAR(pesticides) index. The East African SPEAR(pesticides) index correlated well with the overall toxicity of 30 pesticides measured in stream water. The index also correlated with the risk of surface run-off from agricultural fields, and it was independent of organic pollution and highly specific to pesticides.

Summary: Standardized laboratory tests with a limited number of model species play a crucial role in chemical risk assessments. A multispecies toxicokinetic model based on data from 69 freshwater fish species in Canada was developed to predict bioconcentration, showing promising results with some tendency of overestimating measured values. This bottom-up approach potentially provides more accurate predictions for chemical risk assessments.

Summary: While the frequency and intensity of floods are increasing globally, the indirect effects of pollutants remobilized and redistributed during flood events are often overlooked. A global examination of floods caused by extreme events and the subsequent distribution of sediment-bound pollutants is essential to improve interdisciplinary investigations and develop action plans to address environmental pollution issues from flooding. Action plans for river basins and coastal lowlands need to balance flood retention, catchment conservation, and economical water use.

Summary: This study investigates the impact of ozone treatment on endocrine potential in treated wastewater, finding that the estrogenic potential was nearly fully eliminated while the antagonistic potential did not show a clear elimination pattern. Further investigation is required regarding the antagonistic potential. Additionally, a significant impact was found from runoff events, such as those from rain overflow basins (ROBs), suggesting a need to comprehensively assess polluted surface waters by including other point sources.

Summary: This study investigated the impact of wastewater treatment plants on endocrine-disrupting compounds in the Wurm River, showing that ozonation treatment can completely reduce the activity in water, but sediment activity may be influenced by rain events and potentially released into the water body from rainwater overflow basins. Monitoring both water and sediment phases is necessary to accurately profile endocrine-disrupting activity. Additionally, CALUX (R) assays are suitable for studying endocrine-disrupting activity distribution in different river compartments and WWTP effluents.

Summary: The increasing production and use of chemicals have led to a growing interest in understanding their impact on ecosystems and human health through suspect and non-target screening (NTS). To promote effective implementation of NTS, more harmonisation is needed. The NORMAN Association has prepared a guidance document to provide guidance on conducting high-quality NTS studies and interpreting data while addressing the challenges and pitfalls of these techniques. The document covers various steps of NTS, from sampling and analysis to data evaluation and reporting, and also introduces analytical methods, processing techniques, and databases commonly used in NTS workflows.
