Measuring the quantity of harmful VOCs inhaled through masks

Full Title:"Measuring the quantity of harmful volatile organic compounds inhaled through masks"

" This study demonstrated that disposable masks (KF94) released higher concentrations of TVOCs in comparison to cotton masks, with values of 3730 ± 1331 µg m–3 for KF94 and 268 ± 51.6 µg m–3 for cotton masks. The concentrations of TVOCs in KF94 masks are high enough to pose a concern based on indoor air quality guidelines established by the German Federal Environment Agency."
