Session abstract

During the past decade the focus in eocotoxicity testing of nanomaterials has shifted from identification effects to deeper understanding of the underlying effect mechanisms and especially the importance of controlling and describing the exposure conditions during testing. This has by several research projects been identified as the key to closing important gaps in our knowledge of the cause to ecotoxicity. This session will focus on ecotoxicity of  nanomaterials towards aquatic (including sediments) and terrestrial organisms. Important topics will be how to use characterization data to interpret observed effects, the role of particle coatings and functionalizations, new insights in mechanisms of toxicity for nanomaterials, uptake and depuration of nanomaterials in aquatic and terrestrial organisms and the link between scientific studies and regulatory ecotoxicity testing of nanomaterials.
