Abstract :Ambient air particulate matter samples were collected from urban and suburban sites of Eskişehir in 2012. Samples were collected concurrently from both sites between 26 th of February and 20 th of December 2012. Mass concentrations of particulate matter insert ignore into journalissuearticles values(fine particles- PM 2.5 , coarse particles- PM 2.5-10 and total suspended particulate matter- TSP ); were determined. TSP samples were analyzed by Thermal Optical Carbon Analyzer to determine elemental carbon insert ignore into journalissuearticles values(EC);, organic carbon insert ignore into journalissuearticles values(OC); and total carbon insert ignore into journalissuearticles values(TC); concentrations. It was found that 4.9% of the TSP is composed of EC, and 13.6 % is OC in urban sampling point. EC and OC contributions in suburban sampling points were 2.7% and 9.6% respectively. OC/EC ratio was found to be almost 1.5 times higher in suburban sampling site compared to urban sampling site. EC tracer method was used to estimate the contribution of Secondary Organic Carbon insert ignore into journalissuearticles values(SOC);. The SOC percent of TSP was estimated as 7.1 % and 5.6 % for the urban and suburban locations respectively.Keywords : Particulate Matter, Elemental Carbon, Organic Carbon
