- Field campaigns were conducted to determine indoor emissions of pollutants from household fuel burning in southwest China.
- Indoor CO, PM1.0, PM2.5 and PM10 concentrations were monitored.
- Indoor smoke particle size distributions were characterized during ignition, flaming and smoldering phases.
- Emission factors of indoor black carbon (BC) and organic carbon (OC) were investigated.
- BC and OC emissions from indoor sources in Chinese rural areas were estimated.
Field campaigns were conducted to determine indoor emissions of carbonaceous aerosols and other air pollutants from household fuel burning in southwest China. “1-h peak” concentrations of CO, PM1.0, PM2.5 and PM10 were 14.0 ppm, 200, 220, and 260 µg/m3 for wood and 10.3 ppm, 80, 110, and 180 µg/m3 for coal, respectively. Daily average levels of CO, PM1.0, PM2.5 and PM10 were 5.7 ppm, 100, 110, and 160 µg/m3 for wood and 6.0 ppm, 50, 70, and 100 µg/m3 for coal, respectively. For wood and coal, particle size distribution show a prominent Aitken mode with peaks at around 40–80 nm. Emission factors of BC and OC were 0.57 and 2.69 g/kg for wood and 0.01 and 0.31 g/kg for coal, respectively. The total BC emissions from wood and coal (anthracite) burning in China were 63.3 Gg in 2000 and 81.6 Gg in 2005, respectively.
