Résumé:

In situ analysis of titanium dioxide (TiO2) particles in face masks demonstrated the presence of agglomerated TiO2 (nano)particles in all examined face masks that contain polyester or polyamide (nylon) fibres, or that are made of non-woven, synthetic fabrics. These particles resemble 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 nanoform, was applied for a scenario with intensive use of face masks. Our calculations show that a heal…
