Urban air pollution is a major environmental problem in all World countries. Air pollution in urban areas may be caused by human activities such as mobility behavior, waste management, industrial development (brick industry, cement industry), production and use of energy (for processing, heating and cooking), and activities which produce dust and suspended particles. The effects of urban air pollution on public health are being felt worldwide. There are a number of factors that influence urban air quality including geographical location, climatological and meteorological factors (temperature, humidity, wind speed and direction), city planning and design, and finally human activities in such areas.The aim of this study was to measure certain important pollutants (VOCs, SO 2 , H 2 S, NO 2 ), and assessing the effect of fuel burning that use in the brick factories. Geographic Information System (GIS) was utilized to map urban air pollution dispersion in AL-Nahrawan suburban -Baghdad city -Iraq. From GIS distribution maps for SO 2 , NO 2 , H 2 S and VOCs pollutants , it was found that the value of these gasses were changed from one location to another according to the quantity and quality of fuel used and wind direction. Generally it can concluded that the concentration of measured all examined gasses in the study area was exceeding the WHO and national standards.

Climate change is now more important than before, based on many evidence, humans were affecting on changing Earth’s climate. The atmosphere and oceans have warmed, by sea-level rise, a strong decline in Arctic ice sea, and other climate-related changes. The aim of this study was to calculate some important greenhousse gasses concentration such as CO2, CH4, N2O in AL-Nahrawan suburban -Baghdad city -Iraq. Geographic Information System (GIS) was utilized to map greenhouse gasses dispersion in AL-Nahrawan bricks factory. From GIS distribution maps for CO2, CH4, N2O, it was found that the value of these gasses were changed from one location to another according to the quantity of fuel used in bricks factory, Where the value of emitted CO2 ranged from (695 -854 tones), value of N2O ranged from (1.905 - 2.318 tones), and finally value of CH4 ranged from (0.286 - 0.347 tones).
