ECHA: New Approach on Hazard Assessment for Nanoforms
The European Chemicals Agency (ECHA) announced on March 23, 2016, a new publication co-authored with the Dutch National Institute for Public Health and the Environment (RIVM) and Joint Research Center (JRC) that illustrates how to use data for different nanoforms within the same substance registration.
In order to reduce testing for each different nanoform while still meeting the REACH data requirement, adaptation is an alternative way. The new approach
According to ECHA, the scientific reference paper ‘Usage of (eco)toxicological data for bridging data gaps
between and grouping of nanoforms of the same substance - Elements to
regulators, researchers, industry and NGOs an approach of how to
scientifically justify that studies on one nanoform of a substance can
be used to predict the hazard properties of other forms of the same
substance. It is a joint publication between the European Chemicals Agency (ECHA),
the Joint Research Centre (JRC) and the Dutch National Institute for
Public Health and the Environment (RIVM). EU Member States, NGOs and
industry have been consulted throughout the drafting process.
The paper outlines a stepwise approach to identify opportunities for
using data between nanoforms within the same substance registration. The
identification is based on grouping through an assessment of
physicochemical properties and in vitro
screening methods. According to ECHA, this may allow for a hazard assessment of several
nanoforms of the same substance, minimizing the testing needed,
including testing on animals, and therefore also minimizing costs.
