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

consisting of metallic silver releasing Ag+ ions, Ag0 NP and large silver particles. For metallic and ionic silver, an acceptable exposure level (AEL mask) of 25 µg per mask was established based on ...
