Structure

Source: Biomass fuel
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Setting: home, ET
Study design: measurement study of rural households in Ethiopia cooking with wood on traditional stoves: 24-hour fine particulate matter measured at the domestic hearth, with stove type and door or window opening recorded (class 4)
Effect: mean 410
Averaging time: 24 h
Caveat: households using only traditional stoves and those not opening the door or a window during cooking had significantly higher means
