Measurement of PM10, PM2.5 and TSP Particle Concentrations in Tehran, Iran

Hossein Kakooei and Ali Akbar Kakooei

Short-term exposure sampling of fine particle (PM2.5), coarse particle (PM10) and Total Suspended Particle (TSP) has been carried out at different located in Tehran, the capital of Iran. Samples were collected from summer, to winter of 2005, in North (N), South (S), West (W), East (E) and center of Tehran. The daily monitoring site was located 2 m above ground near highway and main streets. One hundred and seventeen simultaneous sampling of the airborne particle matter (MS) were collected using a direct-reading instrument, the TSI Inc. model 8520 Dusttrack aerosol monitor. The 24 h average PM10, PM2.5 and TSP concentrations during the sampling period were 122.1, 24.3 and 239.8 μg m–3 respectively. Daily PM10 and TSP concentrations exceeded the National Ambient Air Quality Standard (NAAQS) of USA, for approximately 25.7 and 38.9% of the sampling days, respectively. Compared with NAAQS, the average PM2.5 measured concentration (24.3 μg m–3) in Tehran was lower. The results also showed that for north of Tehran, the average particle matter concentrations (153.1 μg m–3 for PM10, 32.4 μg m–3 for PM2.5 and 269.6 μg m–3 for TSP) were higher than other area. The average PM2.5/PM10 ratio for the five area were 0.19 compared to 0.15 to 0.25 reported by EPA. Three season monitoring data indicated that the average concentrations of PM10 in the winter (December to March), summer (Jun to July) and fall (November) were 116.4, 101.9 and 150.9 μg m–3, respectively. PM2.5 levels in the seasons also were 10.9, 21.32 and 12 μg m–3, respectively. These results clearly confirmed the non-parametric analysis (Kruskal-Wallis test) PM10 (p< 0.001), PM2.5 (p< 0.001) and TSP (p = 0.114).
