Aquatic multispecies tests are increasingly used to assess the fateand effects of pesticides in Europe. The rationale for their use,although originally based upon ecological arguments, is now morelikely to be based upon uncertainties surrounding the true exposure of organisms in natural ecosystems. This shift inrationale promotes the design of more focused studies, but does notovercome difficulties associated with the extrapolation of mesocosmand microcosm results to natural systems. Priorities for furtherresearch into these systems should be the extent to which resultscan be repeated and reproduced, and the level of precision andaccuracy of predictions from microcosms and mesocosms to naturalecosystems.
