Finding F-0708
“The average indoor NO2 concentration was somewhat lower compared to the outdoor levels (11.3 vs. 11.5 μg m−3)”
Structure
- Factor
- Nitrogen dioxide (NO₂)
- Population
- preschool children
- Setting
- kindergarten, ZA (April to May 2022)
- Study design
- short communication: passive sampling of nitrogen dioxide and sulphur dioxide indoors and outdoors at 13 randomly selected preschools in 7 districts of Mpumalanga Province, South Africa, in April and May 2022 (class 4)
- Effect
- mean 11.3
- Sample
- 13 rooms
- Caveat
- both averages are above the WHO air quality guideline value of 10 μg m−3 but below the South African standards; the authors note that passive samplers may underestimate the true levels
