Finding F-0893

“Univariate analysis suggested that use of firewood was associated with higher PM2.5 exposures than charcoal (median 115.0 μg/m3 [IQR: 26.7–506.0] versus median 25.7 μg/m3 [IQR: 11.0–65.0] for charcoal).”

Structure

Source: Charcoal
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 25.7
Averaging time: cooking periods
Sample: 20 participants
