Emission factors of carbonaceous particles, includingblack carbon (BC) and organic carbon (OC), and polycyclicaromatic hydrocarbons (PAHs) were determined for fivecoals, which ranged in maturity from sub-bituminousto anthracite. They were burned in the form of honeycombbriquettes in a residential coalstove, one of the mostcommon fuel/stove combinations in China. Smoke sampleswere taken through dilution sampling equipment, with ahigh volume sampler that could simultaneously collectemissions in both particulate and gaseous phases, and acascade impactor that could segregate particles into sixfractions. Particulate BC and OC were analyzed by a thermal-optical method, and PAHs in emissions of both phases wereanalyzed by GC-MS. Burning of bituminous coalsproduced the highest emission factors of particulatematter (12.91 g/kg), BC (0.28 g/kg), OC (7.82 g/kg), and 20PAHs (210.6 mg/kg) on the basis of burned dry ash-free (daf)coal, while the anthracite honeycomb-briquette was thecleanest household coal fuel. The size-segregated resultsshow that more than 94% of the particles were submicron,and calculated mass median aerodynamic diameters (MMAD)of all particles were under 0.3 
m. Based on the coalconsumption in the residential sector of China, 290.24 Gg(gigagrams) of particulate matter, 5.36 Gg of BC, 170.33 Ggof OC, and 4.72 Gg of 20 PAHs mass were emittedannually from household honeycomb-briquette burningduring 2000. Anthracite coal should be selected preferentiallyand more advanced burning conditions should be appliedin domestic combustion, from the viewpoint of bothclimate change and adverse health effects.
