"We are not in a regulatory void," said Cornelis Brekelmans, an official in charge of regulatory aspects of nanotechnology at the European Commission.
Speaking at a conference on 2 October, Brekelmans said this was because EU rules impose a risk assessment on all products, adding that nanomaterials were no exception to this obligation.
"We may decide not to authorise a product," the official warned during the Second Annual Nanotechnology Safety for Success Dialogue Workshop in Brussels. Depending on the outcome of such assessments, the authorities may review, modify or cancel authorisations, he explained.
According to the Commission official, "the real issue is implementation and enforcement". The basis on which a product can be banned must be better identified, he added, calling for enforcement capacities at national level to be strengthened in this respect.
The Commission, he said, remains "convinced that a lot of work still has to be done" on testing, standards and guidelines, while product authorisations must be conducted "on a case-by-case basis".
