Finding F-0194

“Mean indoor PM2.5 and PM10 was 52.5 μg/m3 and 65 μg/m3.”

Assessment of Indoor Particulate Matter and Teacher’s Perceived Indoor Climate in Government Schools of Bilaspur (2024). Indian J Occup Environ Med. Page 1. CKB 1123

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Population: schoolchildren
Setting: classroom, IN (summer)
Study design: cross-sectional survey in nine government-run schools in Bilaspur district: PM2.5 and PM10 measured inside classrooms and outdoors simultaneously for two consecutive summer days with an Atmos monitor, means from mixed effect linear regression (class 4)
Effect: mean 52.5
Flags: source-inconsistent
Caveat: the Results section gives the overall mean indoor PM2.5 as 40 μg/m3 against 37 μg/m3 outdoors, so the abstract figure appears to come from the mixed-effect model
