Airborne emissions from a traditional Paldstani cooking stove were measured and compared for fuels composed of raw and amended coal briquettes, wood, charcoal, and dung. Small charges of fuel, 200 g, were burned inside a 12 m[sup 3] shed with a forced rate of air exchange of 14 hr[sup [minus]1]. The amended coal contained slaked lime, clay catalyst and 1 % potassium nitrate oxidant. The lime proved effective in reducing the integrated S0[sub 2] emissions but not the early peak S0[sub 2] emissions while combustion was restricted to the skin of the briquettes. Volatile and semivolatile organic emissions and respirable suspended particulates (RSP) were considerably reduced in amended coal compared to raw coal briquettes. The measurements overall indicated that, with respect to CO, S0[sub 2], N0[sub 2], organics and RSP, substitution of amended coal briquettes for traditional fuels will not worsen indoor air quality during domestic cooking. Better utilization of Pakistani's reserves of high-sulfur coal is an attractive energy option for both economic and environmental reasons.
