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
control SARS-CoV-2 infection needs to be balanced against possible toxicity due to inhalation exposure. Direct measurement of silver (particle) release to estimate exposure is problematic. Therefore, this ...
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 face masks using electron microscopy and EDX, combined with total silver measurement using ICP- MS or ICP- OES demonstrated the presence of varying amounts and different types of silver-based ...

Identification and characterization of TiO2 nanoparticles in face masks by TEM
particle size measurement of nanoparticles in situ in face masks by conventional and analytical transmission electron microscopy (TEM). The methodology can be applied by following this protocol which ...
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 ...
