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

ICPMS Nanoparticle Risk Assessment Silver textile Abstract: Previous assessments of a selection of face masks intended for the general population in Belgium found that silver (Ag)-based biocides were ...

Application of silver-based biocides in face masks intended for general use requires regulatory control

type(s) and localization of silver-based biocides using electron microscopy based methods. Thirteen of 20 selected masks intended for general use contained detectable amounts of silver ranging from 3 μg to ...

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

biocides in a selection of face masks on the Belgian market and intended to be worn by the general public. Following types of silver-based biocides were demonstrated: (i) Ag+ ions, (ii) metallic Ag0 NP ...

Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
