Sulphur dioxide (SO2) and particulate matter (PM) constitutes of the classical air pollutants have important environmental effects. In the scope of this study, the results of SO2 and PM concentrations measured from 7 districts of Bursa, their spatial fluctuations and the reasons of variations among districts are discussed. Samples were collected with a Bulab 201/8 model semi-automatic sampling device. Monthly average concentrations were calculated for the evaluation of pollutant concentrations. When average concentrations of the districts were assessed, it was observed that the concentrations are dependent on meteorological and topographical conditions, fuel usage and population characteristics.
