Preliminary information on saptial distribuiton of air quality in Bursa, which is city wity population of 600 000, located on the Northwestern Turkey, is being studied using passive sampling. The parameters that are measured by passive monitors include SO₂, NO₂, O₃ and approximately 70 VOCs. Concentrations of these species were measured at 50 locations at a 22 km x 10 km area, which includes residential, traffic impacted and industrial sectors in the city one week at October 2005 and one week in April 2006. An online GC were operated parallel with the passive samplers to determine the uptake rates of the VOC samplers under meteorological conditions that existed during passive sampling interval. The distribution maps prepeared by interpolating data allowed us to differntiate hot spots in the city and identified locations where air quality monitoring stations should have been located. The center of the city with congested traffic, and kukurtlu district, which is densely populated area in the city have the highest concentraitons of VOCs. SO₂ concentrations, on the other hand, were the highest at Osmangazi organized industrial area. Ozone concentrations were low within the city, due to destruction of ozone by high concentration of NO, and high at the peripherals of the city. Sources contributing to observed distributions are determined using poisitve matrix factorization as multivariate statistical tool.
