Given that the ultimate goal of ecotoxicology is the identification of effects at the population and ecosystem levels, microbial communities were picked for reasons of their supreme importance in the environment. Two microbial communities (intestinal microbiomes and environmental microbial biofilms) will be investigated with respect to effects by the test substances (cf. WPs 1 and 2). The intestinal biofilm population shifts may be responsible for the health status of the aquatic organisms, whereas

Results of the multi-level scale approach on effects for the selected micropollutants and their TPs and metabolites will be evaluated and integrated as a base for the creation of a tool box for the ef-fect-based risk assessment. Results will stimulate further work in the development of models linking exposure and effect data with hydrological models. This will require the correlation of results from receptor assays, cell lines and animal models. Microbial data will be linked to the health status

Effect-Net is a multi- and transdisciplinary project that intends to generate a toolbox for multi-scale chemical effects as a basis for a holistic effect-based risk evaluation, and for sociocultural governance aiming at personal and political responsibility as well as a reduction of emissions of hazardous chemicals into aquatic environments. The focus is on the development of a multi-scale network for the identification and evaluation of the biological hazards posed by emerging high-consumption

All data from chemical and biological analyses will be used as sources of data for WP 9. It is not the purpose of Eff-Net to provide a tool to fully model the effects of carbohydrate metabolism-related and neurotoxic substances. Rather, in the sense of an Adverse Outcome Pathway (AOP [33]), the data pool will be analyzed for the suitability of lower scale data (e.g. receptor assay data) to predict the adverse outcome of the test substances at higher levels of organization (e.g. fish). In addition,

In contrast to WP 5, which addresses in vivo effects in early developmental stages of zebrafish as an established model organism in ecotoxicology, WP 6 will use one indigenous fish species and one species representative of invertebrates in order to verify and, thus, validate the data obtained with zebrafish and also those generated at the in vitro levels (WPs 3 and 4) with respect to their ecologi-cal relevance. Possible adverse effects of the test substances identified in WP 1 will be assessed
