and purpose: In this study, the air quality index and concentration of particles such as PM 10 and PM 2.5 were investigated in Arak. Materials and Methods: To determine the concentration of PM 10 and PM 2.5 , 60 samples were collected by laser TSI model 8520 in summer and winter 2012. The collection site was around Arak city center. Results: during the sampling period, as a matter of PM 10 , the cleanest and the most polluted month were December and June with the average of 34.33 µg m -3 and

Meanwhile, in terms of air quality index (AQI), in 98.3% and 70% of cases, the concentrations of PM 10 and PM 2.5 , respectively were less than normal (AQI<100). Conclusion: The concentration of PM 10 in the study period was less than Environmental Protection Agency (EPA) 2006 guideline. Meanwhile, the concentrations of PM 2.5 in 30% of air samples were greater than EPA guideline. The average PM 2.5 /PM 10 ratio during the sampling period was 0.41 compared to range 0.15 to 0.25 reported by EPA. [Fazelinia1 F. Khodabandehlou A. Rafati L. *Mahvi A.
