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

consumers. Direct measurement of release of Ag and TiO particles during normal wearing is problematic by the lack of methodology to test release and to quantify inhaled particles. Therefore in this study, we ...

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

study optimized methodologies to characterize silver-based biocides directly in the face masks, by measuring their total silver content using ICP- MS and ICP- OES based methods, and by visualizing the ...

Identification and characterization of TiO2 nanoparticles in face masks by TEM

textile ultramicrotomy Abstract: Because of the possible health risks related to the use of nanoparticle technologies in face masks, a general methodology is developed for identification, localization and ...

IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021

fibre-grade TiO2 particles. Because there are no methods available for measuring exposure directly, the methodology that ANSES applied to determine the professional exposure limits to titanium dioxide in its ...
