摘 要：Residential coal combustion,and agricultural biomass burning are important primary sources of carbonaceous pollutants in China,resulting a significant impact onair quality and human *** tests were conducted to determine EFs for particle pollutants(***,OC,and EC)from residential coal combustion,and agricultural biomass *** average EFs were estimated to be6.15±7.12 g kg for PM,1.92±2.31 g kg for OC,2.77±3.78 g kg for EC,from coal(*** coal,and anthracite coal) combustion,andl4.41±3.77 g kg for PM,5.92±2.11 g kg for OC,0.43±0.12 g kg for ECfrom agricultural biomass(*** straw,corn stover,and rice straw) burning in China,*** averageOC-to-EC ratio of agricultural biomass was 13.74±2.71,which was significantly higher than the ratios from bituminous coal(1.36±1.32),and anthracite coal(6.33±1.33).Carbon fractions(OC1,OC2,OC3,OC4,EC1,EC2,EC3,and OP) profiles showed that EC1 was the major contributor to bituminous coal,OC2,and OC3 were the dominated contributors to anthracite coal,andOC2,OC3,EC1,and OP were the lager contributors to agricultural biomass *** residential emissionsof PM,OC,and EC in Chinafor 2012 from coal combustion were estimated to be 757,237,and 343 Gg,and from agricultural burning were estimated to be 1238,524,and 37 Gg,respectively.
