Emission Inventory of air pollutants from Biomass Burning in the Pearl River Delta Region, China
Biomass burning has been of increasing concerns for regional air quality issues. Emissions from burning of major agricultural residues were measured by a custom-made laboratory simulation system. Emission factors of CO2, CO, PM10, PM2.5, and OC and EC in PM2.5 were measured to be 1105.2±189.3, 53.2±17.9, 14.0±5.1, 12.1±4.4, 10.53±4.87 and 0.49±0.22 g kg-1 for rice straw burning in flaming condition, 1024.0±207.9, 110.6±37.9, 20.6±14.2, 18.3±13.5, 8.77±4.81 and 0.37±0.11 g kg-1 for rice straw combustion in smoldering condition, and 1152.5±258, 40.1±15.7, 5.65±1.3, 4.12±1.1, 1.25±0.67 and 1.22±0.66 g kg-1 for sugarcane leaves burning, respectively. The activity data of biomss burning were obtained in Pearl River Delta regional by in-house survey as well as quantionaries. The annual emissions of CO, NMHCs, NOx, PM2.5, OC and EC in the PRD from biomass burning for the year 2008 were estimated to be 193.70, 18.34, 5.08, 15.31, 7.76, 2.71 kt, respectively. Field burning of straws made a major contribution to NMHCs, PM2.5 and OC emissions. Residential sector, including firewood and crop straw consumption, was the dominant source of EC, CO and NOx.
