Finding F-1524
“PM1, PM2.5 and PM10 concentrations measured in the five classrooms during spring were, on average, 17.2 ± 4.4, 18.1 ± 4.7, 32.7 ± 10.0 μg·m−3 respectively.”
Structure
- Factor
- Particulate matter (PM₂.₅ and PM₁₀)
- Setting
- classroom, IT
- Study design
- measurement campaign in five naturally ventilated Italian classrooms: particle mass and number, black carbon and carbon dioxide measured indoors and outdoors in winter and in spring during lessons (class 4)
- Effect
- mean 18.1
- Caveat
- the sentence prints the spread as a plus-minus value without naming it; the study sets these against the 24-hour values of 25 and 50 μg·m-3
