Finding F-1555

“The results indicated that cooking in a thatched roof kitchen emitted on average 639 μg/m3 (SD = 181) PM2.5 concentrations, compared with cooking in a CIS roofed kitchen which emitted an average concentration of 336 μg/m3 (SD = 182) PM2.5.”

Structure

Source: Biomass fuel
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: kitchen
Study design: measurement of fine particulate matter in the kitchens of rural households: 24-hour kitchen concentrations measured across roof types, fuels and cooking tasks, with the variation between kitchens analysed (class 4)
Effect: mean 639
Caveat: the sentence prints the spread as a standard deviation in brackets; the corrugated iron sheet kitchens have a standard deviation of 182 μg/m3
