Background Assessing the impact of new technologies or newly developed substances on our environment is a challenge, even more so if the applied test methods - both toxicological and analytical - are often found to be inadequate and need amendments or even new developments as it is in the case of nanotechnology. This is illustrated by numerous publications in the field of nano-ecotoxicology which although they have been investigating the impact of a number of nanomaterials on several organisms almost never allow for explicit statements on potential hazards of these nanomaterials. This fact not only hampers the knowledge communication to all non-scientists (e.g. consumers) but it also complicates the transfer of the obtained results for other scientists. Results Risk communication is an essential and thus integral part of risk management. For this purpose, the project DaNa2.0 (Data and knowledge on nanomaterials - processing of socially relevant scientific facts) provides processed and hence easy accessible information on the potential safety issues of nanomaterials, mainly via the project website www.nanoobjects.info webcite. This will allow various stakeholder groups to get impartial information on potential effects of nanomaterials and help consumers to make informed decisions. DaNa2.0 is funded by the German Federal Ministry of Education and Research (BMBF) and supported by the Swiss government as well as by the European InterReg IVb programme. The DaNa2.0 team is an interdisciplinary group of scientists from different areas such as materials science, chemistry, biology and human and environmental toxicology. Extending the project team in DaNa2.0 with European experts allows for broadening of the existing knowledge portfolio by adding further cross-cutting topics and increasing our expertise, e.g. in the field of environmental exposure and fate. Conclusions On the project website www.nanoobjects.info webcite, a unique link between nanomaterials in practical applications (e.g. environmental remediation) and ...

Nanotechnologies have reached maturity and market penetration that require nano-specific changes in legislation and harmonization among legislation domains, such as the amendments to REACH for nanomaterials (NMs) which came into force in 2020. Thus, an assessment of the components and regulatory boundaries of NMs risk governance is timely, alongside related methods and tools, as part of the global efforts to optimise nanosafety and integrate it into product design processes, via Safe(r)-by-Design (SbD) concepts. This paper provides an overview of the state-of-the-art regarding risk governance of NMs and lays out the theoretical basis for the development and implementation of an effective, trustworthy and transparent risk governance framework for NMs. The proposed framework enables continuous integration of the evolving state of the science, leverages best practice from contiguous disciplines and facilitates responsive re-thinking of nanosafety governance to meet future needs. To achieve and operationalise such framework, a science-based Risk Governance Council (RGC) for NMs is being developed. The framework will provide a toolkit for independent NMs' risk governance and integrates needs and views of stakeholders. An extension of this framework to relevant advanced materials and emerging technologies is also envisaged, in view of future foundations of risk research in Europe and globally.
