Abstract: The study aims to develop a spatial high-resolution emission inventory (2 km × 2 km) of criteria
air pollutants (PM10, PM2.5 CO, NOx, and SO2) for Ghaziabad district. The estimates of the
emissions in a quantitative manner is prepared in an inventory helps us comprehend the actual
emissions in a comprehensive way and help identify sources. The bottom-up gridded emission
inventory has been prepared taking into account population density as well as activity data from
industrial areas, domestic, brick kilns, waste, agriculture, crematoria transport sectors and road
dust re-suspension. The data of the sectors along with emission factor have been acquired from
literature, various regulatory bodies and primary data composition for the study domain.
Emissions of PM10 , PM2.5, CO, NOx and SO2 is estimated for 2017 year for Ghaziabad
district. The total of PM10 , PM2.5, CO, NOx and SO2 are 83.3 kt/year, 27.1 kt/year, 122.4
kt/year, 10.4 kt/ year and 4.5 kt/year respectively. The results reveal that total estimated
emissions from transport, industry and domestic sectors are the most polluting ones in
Ghaziabad district.The use of ArcGIS tool to represent the emissions spatially has established
the spread and concentration of emissions. Further the emissions are used in model AERMOD to
predict the concentration of pollutants for winter and summer months.
