Release of silver and titanium from face masks traded for the general population.
acceptable exposure limit values derived from inhalation exposure limits indicate that three face masks would need further risk assessment and could not be considered as intrinsically safe. Health Topics: ...
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
occupational exposure levels and assuming an intensive exposure scenario considering subchronic exposure of the general adult population. Comparison of the measured amount of total silver in the masks with this ...
IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
health risks, but so far, research and publications of TiO2 particles in textiles, and particularly of their release, are limited. In view of EFSA ’s conclusion that TiO2 cannot be considered any longer as ...
Is aggregated synthetic amorphous silica toxicologically relevant?
of industrial applications. They are primarily produced as nanosized particles (1–100 nm in diameter) and considered safe as they form large aggregates (> 100 nm) during the production process. So ...
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
a median minimal external dimension below 100 nm, should be inserted in the current EU specifications. The Panel considered that the conclusions made, and the uncertainties identified, in the previous EFSA ...
