Structure

Source: Wood
Factor: Carbon monoxide (CO)
Setting: rural home, MW
Study design: measurement study in homes in Malawi: 24-hour particulate matter and carbon monoxide in urban and rural homes with the transition-metal content of the smoke, urban homes cooking mostly with charcoal and rural homes with wood (class 4)
Effect: mean 1.87
Caveat: the same rural homes had the higher particulate matter, so the two pollutants point to different fuels
