In a recent interview, Aurelie Niode of the National Food, Environment and Occupational Health and Safety Agency (ANSES) reiterated her commitment to products containing nanomaterials due to the permanent unknown.
“It is clear that there are still many gray zones regarding population exposure to nanomaterials and their potential health and environmental impacts.”Niaudet, based in the agency’s physical risk assessment unit, says.
“In addition to strengthening regulatory frameworks, it is also important to limit population and environmental exposure by choosing safe products that are equally effective but do not contain nanomaterials as a precautionary measure. . “
Niaudet’s comments came after European food agencies decided that it was unsafe to use titanium dioxide nanofoams, especially as a colorant in food supplements.
Authorities, including the EFSA and the Dutch Food Consumer Safety Authority (NVWA), have emphasized their association with genotoxicity and the long-term effects that result from its accumulation in the body.
The European Commission and 27 EU member states discussed the outcome of the EFSA’s opinion last month and discussed plans to withdraw E171 from the EU-approved list of additives.
The imminent ban is likely to come into force towards September, with enforcement scheduled for the end of 2021.
The expected ban will also affect the use of silver nanoparticles in products such as cosmetics and hygiene products such as food packaging, textiles, toothbrushes, hair straighteners, disinfectant sprays.
Opinion of Ances
The final ANSES assessment of this nanoparticles in 2014 recommended further studies on its physicochemical characterization, exposure assessment, toxicology and ecotoxicology, antibacterial efficacy and bacterial resistance assessment.
The agency also called for improved traceability of data and consumer information about products containing silver nanoparticles. Authorities cannot achieve this traceability with compulsory reporting in the R-Nano database alone. Is emphasized.
“ANSES manages the’R-Nano’register.”Adds Niaudet. “This mandatory filing scheme was established in 2013 to improve the traceability of nanoparticulate materials produced, imported and distributed in France.
“In 2020, an analysis of the scheme highlighted the poor quality of the reported data, and ANSES issued recommendations to the filing companies and ministries to consolidate this register and enhance its usefulness.”
In addition to this work, ANSES is also working with the National Research Program on Environment and Occupational Health (PNR EST) to fund research projects on the impact and environmental fate of nanomaterials and to monitor population exposure. is.
Advantages of nanomaterials
The very small size of nanoparticles gives the material new properties such as resistance, conductivity, and the ability to transport other substances.
While these traits are highly sought after, they can also provoke certain types of behavior when interacting with humans and the environment.
“We know that we can cross physiological barriers such as the skin and respiratory tract, but some have certain types of toxicity.”ANSES highlights.
“When the human body is exposed, the potential distribution and accumulation of these nanomaterials in various organs becomes a problem.”
“Today, there is no clear definition of nanomaterials yet.”Neardet concludes. “Apart from size, the definition currently proposed by the European Commission takes little consideration of physicochemical parameters.
“Therefore, to protect people, we need to be practical and, above all, understand the nanomaterials we are most exposed to.”
