The intensive use of pesticides causes many disturbances in aquatic ecosystems, which are well known to offer a range of "ecological services" for society. In terms of ecotoxicology, environmental issue is not limited to the risk assessment of a pollutant toxicity on organisms but it expands to the ability to assess, at the ecosystem scale, the consequences of a disturbance and the use of bio-indicators. In this context, for aquatic ecosystems, phototrophic biofilms provide a particularly relevant model, based on their complex microbial community structures, spatial and temporal dynamics and variety of functions. In a first experiment our results suggested that microbial aggregates from different habitats (activated sludge and phototrophic ...
