Versions Notes
The authors wish to make the following amendments to their paper published in International Journal of Environmental Research and Public Health [1]:
  • Page 6880, Table 3: “FEV1/FVC[%]” should read “FEV1/FVC”.
  • Page 6880, Table 4: “10,000 Number/cm3 (PNC)” should read “10,000 /cm3 (PNC)”, “FEV1/FVC (%); Percentage Point * 1000” should read “FEV1/FVC × 1000”. The items for FEV1 for Toasting Bread and Frying Sausages were missing. The correct Table 4 should be:
Table
Table 4. Mean effect estimates and 95% Confidence Interval (CI) for changes (difference) associated with an increase in particulate metrics post 4 h and 24 h post exposure and for different exposure scenarios for PMC, PSC and PNC. Changes refer to an increase of 10 µg/m3 (PMC), 100 µm2/cm3 (PSC) and 10,000 /cm3 (PNC).

Notes: * adjusted for age, height, sex, temperature, humidity, travel time and means of transportation. Abbreviations: FEV1: forced expiratory volume at 1 s, FVC: forced vital capacity, MEF25%–75%: averaged forced expiratory flow between the full expiration of 25% and 75% of the total FVC, CI: confidence interval; marked in bold: effect estimates where CI did not include the null effect. PMC: particle mass concentration; PSC: particle surface concentration; PNC: particle number concentration; LDSA: lung deposited surface area.
The authors would like to apologize for any inconvenience caused to readers by these changes.
