Finding F-0901

“This again contrasted with CO concentrations, which were lower during cooking episodes using firewood stoves than with either three-stone fires or charcoal stoves (median 1.0 ppm [IQR: 0.0–3.0]; median 4.0 ppm [IQR: 1.5–11.5]; median 5.0 ppm [IQR: 1.5–14.0], respectively).”

Structure

Source: Charcoal
Factor: Carbon monoxide (CO)
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 5.0
Averaging time: cooking episodes
Sample: 20 participants
