Abstract The aim of this study is to estimate the premature mortality caused by long-term exposure to elevated concentrations of PM2.5 (particulate matter with aerodynamic diameter equal to or less than 2.5 μm) in Sohar, Sultanate of Oman, from 2014 to 2015. The premature mortality is calculated based on a relative risk of 1.04 (95 % CI, 1.01–1.08) per 10 μgm−3 increase above the annual mean limit of 10 μgm−3 taken from the World Health Organization Air Quality Guidelines (WHO-AQG). The spatiotemporal variations of PM2.5 are estimated based on the measurements of PM2.5 by the Air Quality Monitoring System (AQMS) at Sohar University. The findings of this study show that there are many challenges for estimating the health effects of PM2.5 in places like Oman where it is affected by dust storms originating from the deserts in neighboring countries, and the background concentration of PM2.5 exceeds the WHO-AQGs.
