Report on existing Grouping Strategies (NANoREG, OECD, ECHA or others) and available datasets from other projects (e.g. NANoREG, NanoTEST, MARINA) State of the Art Analysis

Content: Report on the existing grouping strategies based on ongoing activities in other projects (e.g. NanoREG I, Nanosolution, NanoMile or others) or from organizations like OECD, ECHA, ECETOC. This will be compiled as an state-of the art description. In parallel we will identify available datasets for developing grouping from other finished or nearly finished projects. Impact: This is the basis for our own work to be done in Task 1.4
