CO is one of the main airpollutant which leads to many problems for human. Mega cities such as Tehranhave critical issues by increasing the vehicles, fuel usage and urban areaexpansion. Hence, to have a clear view points on the pattern of COconcentration in Tehran, the data of 14 air quality concentration centers in amidterm period 2009 and 2012 are used. The main novelty of this research isusing the third quartile Q3 as the pollution indicator which leads to moreaccurate results based on the exposure pattern in a day. Additionally, bySpline interpolation model and using ArcGIS software the zoning maps to showthe CO concentration in urban area are illustrated and discussed. Using Q3instead of the mean values showed more accurate results due to the exposurepatterns. Due to the results, the CO concentration shows a downward trend andthe most changes are in the Western side of the city.
