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 ...
Silver-based biocides and titanium dioxide particles in face masks for general use. Final report of the TiO2Mask and AgMask COVID-19 projects.

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 ...
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 ...
Titanium dioxide particles frequently present in face masks intended for general use require regulatory control

A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
particles detected with sp- ICP- MS and TEM. Conventional fractionation by centrifugation and dialysis generally yielded similar fractions as FlFFF but membrane filtration overestimated the large size ...
Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution
rutile generally containing small amounts of the other phase (rutile or anatase, < 2% m/m) and it may also contain small quantities (< 0.5%) of constituent particle growth and crystal phase control ...
