Release of silver and titanium from face masks traded for the general population.

investigated leaching experiments using artificial acid sweat as a method to evaluate the release of Ag-based biocides and TiO particles present in face masks. Leaching experiments were proposed as an ...

Evaluation of the types, efficient use and health risks of application of silver-based biocides to provide antimicrobial properties to face masks applied during the Covid-19 crisis

a more refined risk evaluation. The amount of silver in the four masks that contain Ag0 NP, Ag+ ions, and/or non-nanoparticulate silver exceeded the AEL mask. Per case an in depth risk analysis needs to be ...
