Wearing a face mask results in exposure to dangerous concentrations of carbon dioxide in inhaled air, even when the mask is worn for just five minutes when sitting still, a study has found.
With surgical masks, the CO2 concentration of inhaled air exceeded the danger zone of 5,000 ppm in 40% of cases. With FFP2 respirators it exceeded it in 99% of cases. The CO2 concentrations were higher for children and for those who breathed more frequently.
