Release of silver and titanium from face masks traded for the general population.
present in masks advertised for antimicrobial properties; whereas titanium dioxide (TiO) particles were detected in all the face masks in at least one layer corroborating its widespread use in the textile ...
Silver-based biocides and titanium dioxide particles in face masks for general use. Final report of the TiO2Mask and AgMask COVID-19 projects.
Publication Type: Sci. report, recommendat°, guidance doc., directive, monograph Authors: Daniela Montalvo; Charlotte Wouters; Lisa Siciliani; Christiane Vleminckx; Erik Van Miert; Nadia Waegeneers; Joris Van Loco; Eveline Verleysen; Karlien Cheyns; Jan M ...
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 ...
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
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

IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
nanoform, was applied for a scenario with intensive use of face masks. Our calculations show that a health risk cannot be excluded for most of the examined face masks when intensively used. The applied ...
METROFOOD-RI: Pilot services with physical, remote and virtual access
this model of service provision, three use cases have been defined that are representative of the different types of access that will be provided by METROFOOD- RI: physical access to a food pilot plant ...
Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo
terms agglomerates and aggregates are frequently used in the regulatory definition(s) of nanomaterials (NM s) and hence attract attention in view of their potential influence on health effects. However, ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
for use as a food colorant in the European Union. The application of E171 in food has become an issue of debate, since there are indications that it may alter the intestinal barrier. This work applied ...
