The basic design area of the city is 14503 hectares and the populated area within this design is 4711 hectaresThe research problem is to discuss how much furnaces and bakeries contribute in the concentration of air pollutants of carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides, and sulfur dioxide those results from burning kerosene fuel. What is the possibility of detecting the spatial variation of these concentrations within a specified period through the use of propagation and dispersion models in the city of Diwaniyah?The hypotheses respond to these questions that the extent of the contribution is related to the number of furnaces and bakeries and quantities of fuel consumed and quality as well as the nature of climatic conditions. The emission factors can be used to estimate the concentrations of gases emitted from those furnaces and bakeries.Furnaces and bakeries are specific emission sources (pointers), based on this characteristic, a model can be simulated to simulate the movement of its emissions by means of Gaussian mathematical equations that depend on wind speed, direction, air temperature, gas type, emission time and surface nature. Thus, Maps that represent the spatial limits of the spread and dispersion ranges can be then mapped for a selected time period.The research methodology is based on the analytical descriptive approach, and the methods of automated analysis are used in GIS.One of the most important tools that is used Aermod View v8, which is used to model furnace and bakery emissions, a program approved by the US Environmental Protection Agency. Arc Gis 10 is also used for automated analysis and some calculations of interest to the search as well as the final output of the maps. The research reveals that the emission levels of the furnace chimney are distributed at a distance of up to 100 meters, depending on the type of pollutant. The most concentrated levels appear after a distance of 2 meters to 30 meters of this chimney.The highest pollutant emissions take a bow-like shape in January, which in fact indicates the more frequent wind trends.During the month of July, the arc form of these contaminants also appears, but it is almost reversed in its direction with the arch formed in January and is formed for the same reason.Higher emission levels range from 5-8 levels surrounding this source and by pollutant type, and the total area exposed to emissions of this source during the month of January is more than in the month of July.As for the calculation of the areas exposed to emissions resulted from emissions sources according to residential quarters are Alsader Alulla,Orubba Alulla, they are the most exposed to the area of emissions of furnaces and bakeries because of the number of bakeries and furnaces in it, While the less disposed quarters to emissions are:Alabrar,Alansar,Tameem,Althaqalain,AlJazaer,Aljnoob,Alhawra,Alaeem,Algadeer,Alkrama,Almutaqaedeen,Almualimeen,Ramadan quarter.
