Finding F-0734

“Cooking periods were associated with 7 times higher household CO concentrations compared with heating periods (94 ± 56 ppm and 13 ± 11 ppm, respectively).”

Structure

Source: Solid fuel
Factor: Carbon monoxide (CO)
Population: heads of nomadic households
Setting: nomadic home on the Himalayan Plateau at 3500 m, CN
Study design: field study among Himalayan nomadic households in Qinghai, China, at 3500 m: household carbon monoxide monitored in 100 homes during cooking and during heating-only periods, with carboxyhaemoglobin as an exposure biomarker in 100 male and 100 female heads of household over three days, analysed with linear mixed-effects models against activity patterns (class 4)
Effect: mean 13
Sample: 100 homes
Caveat: the authors read heating alone as enough to lift exposure above the WHO guideline
