Background and Objectives: Emission inventory of mobile sources is an essential element for studying the air quality. In order to support the development of public policies with an approach to reducing the overall mass emissions of air pollutants, the aim of the current study was preparation of a GIS based emission inventory of Karaj mobile sources air pollutants.
Material and methods: In the present study in 2016, the International vehicle emission model (IVE) was used to estimate the amount of emissions of CO2, CO, NOx, VOCs, SOx and PM and the GIS environment was used to show the distribution of pollutants emissions during the morning rush hours in Karaj pathways.
Results: The results showed that the maximum amount of air pollutants released during morning rush hours was as CO2 (5944.07)> CO (297.55)> NOx (32.70)> VOCs (31.16)> PM (21.24)> SOx (1.102) Kg/h in Karaj. Heavy vehicles were responsible for maximum emission of CO2, NOx and PM and light vehicles were responsible for the release of CO, VOCs and SOx.
Conclusion: This inventory is useful for politicians and researchers to better understand the current conditions of air pollution in the region and will provide a vital input for air quality modeling and policy making.
Keywords: Emission inventory, Air pollution, Mobile sources, Morning rush hour, Karaj
