Finding F-0894

“In contrast, CO exposures were slightly lower during cooking periods using firewood compared with charcoal (median 3.5 ppm [IQR: 1.0–10.0] versus median 5.0 ppm [IQR: 1.5–14.0]).”

Structure

Source: Wood
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 3.5
Averaging time: cooking periods
Sample: 20 participants
Caveat: carbon monoxide runs the other way round from PM2.5 here: firewood gave more particles but less carbon monoxide than charcoal
