Finding F-0757

“Only 20 participants had average CO levels above the WHO recommended 24-h CO exposure level of 7 ppm; however, 51 participants experienced CO exposures over the recommended 15-min exposure level of 100 ppm and 120 participants had 1-h averages greater than the recommended level of 10 ppm [17].”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Population: children under 5 years
Setting: home, MW
Study design: cross-sectional assessment at recruitment to the Cooking and Pneumonia Study, a cluster-randomised trial of cleaner-burning biomass cookstoves in rural Malawi: 48-hour personal carbon-monoxide monitoring of 1928 children under five with carboxyhaemoglobin measured in 1520 of them, against household characteristics and cooking practices from questionnaires (class 4)
Effect: share-above 20
Averaging time: 24 h
Sample: 1928 children
Caveat: a count of children, not a share
