Kermanshah as fairly important industrial city suffered from air pollution specially dust storm during the recent decade. The main purpose of this study was to compare quantitatively the health impacts of PM10 on citizens of Kermanshah city during two successive years. The hourly data of PM10 was taken from Kermanshah Environmental Protection Agency (KEPA) which was measured by Beta attenuation method. We used a health effect model for quantification which was based on baseline incidence (BI), relative risk (RR) and attributable proportion (AP). Our findings showed that 7.6, 11, 15.1, 13.5 and 7.6 percent of total mortality (TM), cardiovascular mortality (CM), respiratory mortality (RM), hospital admission respiratory disease (HARD) and hospital admission cardiovascular disease (HACD) were attributable to short term exposure to PM10, respectively in 2011. With regarding to two years in view of short term health effects, we observed that 20 percent reduction occurred in 2012 compared with 2011. We also concluded that 48 and 12 percent of all health impacts were attributed to occurrence of Middle East Dust (MED) storms during 2011 and 2012, respectively

The aim of this study is to survey the PM₁₀, PM_2.5, and PM₁ concentrations in rural and urban areas in Tehran province during cold, warm and dust storm days from December 22, 2016 to June 5, 2017 using Grimm Model aerosol spectrometer. During the study period, daily PM₁₀, PM_2.5, and PM₁ concentrations ranged from 27.2 to 244.96, 8.4 to 77.9, and 6.5 to 56.8 μg/m³ in urban sites, and 22.8 to 286.4, 6 to 41.1, and 2.1 to 20.2 μg/m³ in rural parts, respectively. Particularly, both daily WHO limits for outdoor PM₁₀ (50.0 μg/m³) and PM_2.5 (25.0 μg/m³) exceeded in 95% and 83% of the outdoor measurements in winter and 82% and 58% in total sampled days in urban site, respectively. The 24-h average PM₁₀ and PM_2.5 concentrations also exceeded by 59% and 18% in winter and by 36% and 14% of all sampling days in rural site, respectively. During the dust storm, the 24-h average PM₁₀, PM_2.5, and PM₁ concentrations were, respectively 4.7, 2, and 1.96 times higher than those in urban site and 2, 1.7, and 1.3 times more than those in rural site in all sampled days.
