Warning on nanoparticles in masks in Holland

After Belgium, the Netherlands has questioned the safety of oral masks with “anti-viral” and “anti-bacterial” claims. The Dutch National Institute for Public Health and the Environment (RIVM) publishes a report on non-surgical oral masks, in which 9 substances used as biocide coatings are identified. Among them: nanosilver, nano-copper, titanium dioxide and graphene.
While the effectiveness and non-toxicity of these coatings are still not assured, and masks are becoming a permanent feature in our daily lives, the institute recommends stepping up efforts to better take into account the potential risks associated with their use. To this end, AVICENN has called on the sanitary authorities and Anses should publish a report soon.
