Sediment-dwelling organisms are at potential risk due to polluted sediments. Although some well-established sediment tests exists for a few species there is a lack of cost-effective and widely accepted methods to assess potential effects on different taxonomic groups, between freshwater, estuarine, and marine ecosystems and at the population and community level. In addition, spatio-temporal extrapolation of test results requires mechanistic understanding of exposure pathways and effects, as well as prospective models. Therefore, the aim of this study is to develop improved methods and assess potential effects of contaminated sediments on aquatic microorganisms, plants, and invertebrates within and across different taxonomic groups, which can be applied in a regulatory context.
