The amounts of nine atmospheric pollutants emitted in Wuhan in 2014 were calculated by a comprehensive investigation of pollution sources and analyzing atmospheric pollutants emission factors as per the public manual and literature.A 3 km×3 km gridded emission inventory was developed based on distribution parameters such as coordinates,population,land types,and road network.The results showed that the total emissions of SO₂,NO_x,PM₁₀,PM_2.5,CO,BC,OC,VOCs,and NH₃ in Wuhan in 2014 were 103 thousand,170 thousand,163 thousand,71 thousand,631 thousand,6 thousand,4 thousand,198 thousand,and 16 thousand tons,respectively.Fuel combustion sources contributed the most to SO₂ emissions,accounting for 64% of the total.Mobile sources contributed the most to NO_x emissions,accounting for 51% to the total.The major emission sources of PM₁₀ and PM_2.5 were fugitive dust and industrial production.Industrial production also served as a major emissions contributor of CO and VOCs.BC and OC emissions were mainly attributed to mobile sources and biomass burning.NH₃ emissions mainly resulted from agricultural sources.Air pollutant emissions were typically concentrated from the Qingshan to the Xinzhou administrative regions.
