Abstract

Aims: In this study, the concentration of PM10 and PM2.5 in eight station of Khorramabad city was analyzed. Materials and Methods: For this study, the data were taken from April 2010 to March 2011. The eight sampling point were chosen in account to Khorramabad maps. During this period, 240 daily PM samples including coarse particle (PM ₁₀ ) and fine particle (PM _2.5 ) were collected. A two-part sampler was used to collect samples of PM. According to one-way ANOVA, multiple comparisons Scheffe, the obtained data were analyzed and then compared with the Environment protection organization standard rates. Khorramabad Results: The results revealed that during measuring the maximum concentration of PM ₁₀ and PM _2.5 was respectively 120.9 and 101.09 μ/m ³ at Shamshirabad station. There was a significant difference between the mean values of PM ₁₀ concentration (μg/m ³ ) in the seasons of summer. In addition, the mean concentrations of PM ₁₀ in warmer months exceeded to the maximum permissible concentration. Conclusions: Year comparison of PM ₁₀ and PM _2.5 concentration with standard were revealed particle matter concentration in summer season was higher than standard. Although total mean of particle matter was less than standard concentration.
