Scientists have published an article describe the requirements and challenges for the implementation of legislation on nanomaterials in food and consumer products in Europe.
The researchers from the European Commission's Joint Research Centre (JRC) highlight that there is an urgent need for methods to identify and characterise nanomaterials and to assess their presence in consumer goods, as well as validation techniques and reference materials to ensure the quality of regulatory assessment.
In a second paper, JRC researchers have reviewed the currently available analytical methods for the measurement of nanoparticle size in products, to be used in safety testing and labelling analysis.
They conclude that there is currently no single technique available that can provide a robust analysis, but highlight that such a method will be needed to implement the European Commission's definition of a nanomaterial for regulatory purposes. However, they suggest a potential solution via the combination of different measuring techniques which may allow suitable analysis of consumer goods containing nanomaterials.
Both papers are published in the journal Food Additives & Contaminants: Part A: Chemistry, Analysis, Control, Exposure & Risk Assessment.
