GRACIOUS approach to Quality Assessment of Nanosafety Data

Event Date: 28th June 2021 - 28th June 2021

Assessing Quality and Completeness of Nanosafety Data for Risk Assessment Purposes Workshop

Start: 10:00 CEST | End: 12:00 CEST


Using high quality data is essential for performing robust risk assessment of chemical substances, including engineered nanomaterials (NMs). It is important for risk assessors to be aware of the quality of the datasets that they use, but such information is currently not available for most of the available nanosafety datasets.

To address this issue, the EU H2020 project GRACIOUS proposed a methodology to facilitate the evaluation of quality and completeness for sets of NM physicochemical and(eco)toxicological data based on established criteria: i.e., completeness, reliability, relevance and adequacy. This approach is unique in the sense that it can automatically assess data quality and completeness starting from the available (meta)data, thus minimising the reliance on expert judgment. The goal is to further advance the methodology in the H2020 Gov4Nano project and implement it as functionality of the eNanoMapper database to enable real-time analysis of each dataset that is included in it. 

To achieve this, we need help from experts!

Therefore, we are organising this virtual workshop to present our approach and collect your opinion on key aspects of the developed quality assessment methodology. 

In this workshop you will learn and discuss:

  • The background and purpose of the GRACIOUS approach for data quality assessment
  • The detailed methodology for assessing data quality and completeness of physicochemical and hazard datasets
  • How the approach can help to address stakeholder needs
  • How we can improve certain aspects of the methodology and its implementation in the eNanoMapper database

Who should attend?

Data experts and risk assessors from industry, regulation, and academia.

Dr. Danail Hristozov is the Head of Research at Greendecision Srl, a spin-off company of University Ca’ Foscari of Venice in Italy and the East European Research and Innovation Enterprise (EMERGE) in Bulgaria. There he performs integrative research across the areas of risk assessment and management of bio and nanomaterials used in consumer products and medicine as part of the large-scale EU H2020 projects GRACIOUS, BIORIMA, REFINE, caLIBRAte, Gov4Nano, NanoInformaTIX and SAFE-N-MEDTECH. Danail is also Coordinator of the large H2020 research project SUNSHINE, which focuses on Safe and Sustainable by Design of multi-component advanced nanomaterials.

Danail has been a senior research scientist at the Department of Environmental Sciences, Informatics and Statistics of University of Venice, where he acted as the Principal Investigator of the large EU FP7 project SUN. Over the last years Danail contributed to several EU projects, including MARINA, NANOforART, ENPRA, ITS-NANO, GLOCOM, ECONANOSOPRB and EPSEI, also as research staff of the private sector companies Venice Research Consortium and Veneto Nanotech. In his early years as a researcher, Danail was employed at the Chair of Industrial Sustainability of the Brandenburg University of Technology in Germany.


Dr Hubert Rauscher

European Commission, DG Joint Research Centre (Ispra, IT)

Hubert has worked on the physicochemical characterisation of nanomaterials for over 20 years, having been a lecturer at the University of Ulm, Germany, and as scientific officer for the European Commission’s Joint Research Centre (JRC). He has contributed to several EU projects on nanomaterials and their safety, including NANoREG, NanoDefine and SUNSHINE. His current focus at the JRC is on providing scientific policy support on nanomaterials, nanosafety and regulatory methods, and nanogovernance.
