RiskGONE (riskgone.eu/) has registered twelve ERM identifiers for the nanomaterials selected for use in the round robin validation exercises for human and environmental health assay pre-validation. Within the project, these identifiers are linked to a label (currently "RiskGONE NM 1-12"), supplier, supplier code, and batch or vial number. This information is currently kept in a private repository for internal use, and stored as a versioned Markdown file, with Word and PDF exports for convenience. The ERM identifiers are used in the project`s documents, deliverables and reports and are integrated in the eNanoMapper database data entry workflow . The RiskGONE data entry templates are following the current Nanosafety Cluster practice of using Excel templates for data logging. Physico-chemical characterization data generated by project partners is entered into a NANoREG style template for physchem properties and data from in vitro toxicity tests for human and eco-toxicological hazard assessment is entered into adapted IOM-Nano-EHS data templates , which have been developed over the last decade and used by a number of EU FP7 and H2020 projects. All templates are distributed through an online Template Wizard tool (search.data.enanomapper.net/projects/riskgone/datatemplates/), and include a dedicated "Materials" sheet, which is automatically filled in with the ERM identifiers, names, types, and other details of the materials used in the project. This spreadsheet serves as a lookup for selecting the materials on data entry and ensures consistent use of material identifiers across the project.
