|Abstract:||KEYBIOEFFECTS was a Marie Curie Research Training Network (RTN) aiming to gain a deeper understanding of the anthropogenic toxic compounds released in European water bodies. Several researchers focused their studies on environmental risk assessment of pollutants. Sophisticated modelling approaches were developed using environmental data provided by water agencies (Catalonia, NE Spain and Adour-Garonne watershed, SE France). Based on available data, it was possible to map areas with higher potential impact due to pesticides, heavy metals or surfactants. In other investigations, the simultaneous study of chemical and biological data allowed to link chemical pollution with population or community changes. In the river Llobregat (Catalonia), biodiversity losses were associated with herbicide (triazines) pollution, and this finding was supported by results obtained in microcosms under controlled exposure conditions. In another investigation, fish (Squalius cephalus) morphology (life traits) was significantly affected by the presence of toxic pesticides investigated along a pollution gradient in the Adour-Garonne river basin. Omic technologies such as transcriptomics and metabolomics were developed by other researchers. These new approaches are expected to contribute to better address the multi-faceted effects of chemicals on biota as well as the interaction with other chemical, physical and biological stressors in future environmental studies. The influence of chemical pressure on river organisms was confirmed at a smaller scale by means of active bio-monitoring: ¿in situ¿ translocations experiments. This approach allowed demonstrating the impact of metal pollution (Zn) and the herbicide prometryn on fluvial communities (biofilms) under real conditions. Other investigations performed in microcosms under controlled exposure conditions were used to develop or validate a set of biomarkers of toxic exposure using fluvial biofilm communities. Furthermore, KEYBIOEFFECTS provided tools to overcome existing gaps in the identification of key toxicants using Effect-Directed Analysis and computer tools, identification of transformation products, and in the quantification of the influence of environmental conditions on toxicant bioavailability, retention and trophic transfer.|
