4 Νοε 2022 · The antibacterial efficacies of cloth face masks coated with TiO2 were measured by inoculating them in bacterial suspensions (105 CFUs from both E. coli and S. aureus).
15 Φεβ 2022 · Although titanium dioxide (TiO 2 ) is a suspected human carcinogen when inhaled, fiber-grade TiO 2 (nano)particles were demonstrated in synthetic textile fibers of face masks intended for the general public. STEM-EDX analysis on sections of a variety of single use and reusable fac …
2 Οκτ 2021 · After as little as three minutes, carbon dioxide in children’s masks have been measured to be in the region of 13,000 ppm, more than six times the maximum carbon dioxide exposure. Younger children tend to have the highest values. Significantly lowered levels of oxygen have also been found in the air under masks.
8 Νοε 2021 · Summary. Belgian study finds titanium dioxide in synthetic masks. EU authorities say no evidence to suggest risk to health. As precaution, Belgium urges to set TiO2 limits for masks.
4 Νοε 2022 · When TiO2 nanoparticle solutions of a high concentration (2%) were applied to face masks against E. coli and S. aureus, efficacies of 3.7 and 3.34 log reduction were obtained, respectively, which is considered strong antibacterial activity (Table (Table1). 1).
29 Οκτ 2020 · When testing several batches of face masks intended to be put on sale as personal protective equipment (PPE), the consumers’ association ‘Adiconsum Veneto’ found that approximately 70% of them – mainly surgical masks – contained titanium dioxide (TiO2) in quantities ranging from 100 ppm to 2000 ppm.
