Finding F-0896

“Use of three-stone fires was associated with higher PM2.5 exposures than either firewood or charcoal cookstoves (median 127.0 μg/m3 [IQR: 30.7–535.0]; median 39.5 μg/m3 [IQR: 9.8–221.0]; median 26.7 μg/m3 [IQR: 11.3–68.0], respectively).”

Structure

Source: Wood
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Population: adults in a rural village
Setting: personal exposure of the participant in the household, MW
Study design: observational study in a rural village of Malawi: twenty adults wore paired personal PM2.5 and carbon-monoxide monitors for 831 hours in total, with a structured activity diary, and exposures were split into activity peaks and background periods and modelled against fuel, stove and place of cooking (class 4)
Effect: median 127.0
Averaging time: cooking episodes
Sample: 20 participants
