Mortality and morbidity due to exposure to ambient particulate matter.

The aim of this study was to investigate spatial variation and health risk of the exposure to PM (particulate matter with a diameter of 2.5 µm or less) and PM (particulate matter with a diameter of 10 µm or less) in Sabzevar, Iran. PM and PM were measured during three campaigns from April to November 2017, in 26 sampling points.
