Finding F-0091
“During the year, the average share of natural ventilation in increasing the concentration of indoor particles was more than 39%.”
Structure
- Factor
- Particulate matter (PM₂.₅ and PM₁₀)
- Intervention
- Natural ventilation
- Setting
- home, IR (August 2020 to July 2021)
- Study design
- measurement study: indoor and outdoor PM2.5 and PM0.4 sampled at four fixed residential stations in Tehran over four seasons (August 2020 to July 2021), 6- to 12-hour samples, source shares estimated from the measurements (class 4)
- Effect
- other 39
- Averaging time
- annual average
- Caveat
- printed as more than 39 %; natural ventilation here brings outdoor particles indoors, it is not a mitigation
