Emission inventory of air pollutants in China

CAO Guo-liang1*,AN Xin-qin2,ZHOU Chun-hong2,REN Yan-qing1,TU Juan1(1.School of Environmental and Municipal Engineering,Xi'an University of Architecture and Technology,Xi'an 710055,China;2.Chinese Academy of Meteorological Sciences,Beijing 100081,China)  
Reactive gas is the important precursor for aerosol formation,acid rain,photochemical smog and other environmental issues.The detailed high-resolution emission inventories of reactive gas from China in the year 2007 were carried out,based on the latest fuel consumption data,mostly at the county level,including fossil and biomass fuels and socio-economic statistics that were obtained from government agencies.Some new emission factors from local characteristization also were used.National and regional summaries of emissions were presented using 0.5°×0.5° resolution.The calculated SO2 emissions were 31.584 million tons,mainly sourced from the burning of coal.while,NOx and CO emissions were 24.926 and 157.852 million tons respectively,predominantly generated from the burning of coal and biofuels.NH3 emissions were 16.017 million tons,mainly sourced from animal waste disposal and fertilizer application.VOCs emissions were 37.098 million tons,mainly from the organic solvent application,waste disposal and transport.The emissions of reactive gas estimated here were higher than those in previous studies,mainly because some emission sectors were previously underestimated.More emissions were emitted from eastern China than western China.A strong seasonal dependence was observed for emissions,mainly due to seasonal changing of residential heating and biomass burning behavior.
