%X Emission factors for CO2, CO and main hydrocarbon gases, as well as biomass consumption in an Amazonian forest clearing fire are presented and discussed. The experiment was conducted in the Western Amazon region, near the city of Cruzeiro do Sul, Acre state, Brazil. The average carbon content of dry biomass was 48% and the estimated average moisture content of fresh biomass was 42% on wet weight basis. The fresh biomass on the ground before burning was estimated as 583 ton ha-1 for larger parts of biomass with characteristic diameters larger than 10 cm. The small parts with characteristic diameters lower than 10 cm were quantified before burning on the ground and represented a value of 105 ton ha-1 with 17.1% humidity. The carbon content on the ground before burning was estimated to be 191 ton ha-1. The overall biomass consumption for the experiment was calculated as 22.5% and 89.2% for larger and small parts of biomass, respectively. Excess mixing ratios were measured for CO2, CO, CH4, C2C3 aliphatic hydrocarbons, and PM2.5. Excess mixing ratios of CH4 and C2C3 hydrocarbons were linearly correlated with those of CO. The average emission factors of CO2, CO, CH4, NMHC, and PM2.5 for 3 sampling hours were 1,513, 157.3, 8.17, 3.89, and 1.86 g kg-1 of burned dry biomass, respectively. Thus one hectare of burned forest released about 232,115 kg of CO2, 24.141 kg of CO, 1.254 kg of CH4, 596 kg of NMHC and 285 kg of PM2.5.
