Finding F-1745

“Mean peak indoor PM2.5 (defined as >2 SD of the mean level over the entire sampling window) was 1790 μg/m3 in homes using biomass and 141 μg/m3 in non-biomass homes (arithmetic means 2828 and 335 μg/m3, respectively).”

Structure

Source: Biomass fuel
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: home, NP
Study design: cross-sectional study of rural and urban Nepalese adults: 24-hour indoor fine particulate matter and carbon monoxide measured in biomass-using and non-biomass-using homes, with respiratory symptoms recorded by questionnaire (class 4)
Effect: other 1790
Caveat: a mean of the peaks rather than an average concentration
