Almost all air pollutants comefrom production and energy use. In the present work, an assessment of some heavymetals, natural radioactivity and the quantity of dust fallen in three sites (Tessen,Rahemawa, and Laylan) in Kirkuk Governorate, northern Iraq. Three dust sampleswere collected from three locations (residential, commercial and industrial areas).The collected samples were analyzed for Cd, Cr, Cu, Ni, Pb, Zn, and radioactivity(Gamma rays). The studied heavy metals (Fe, Ni, Pb, and Zn) exceeded their limitsin the atmosphere due to the increase in the number of automobiles, which addedpollutants to the atmosphere through the fuel combustion in automobiles. Theindustrial processes, especially the petroleum industry considered the most dominantin Kirkuk Governorate, and anthropogenic activities also participated. ChromiumCr, Cu and gamma-ray were within the acceptable limits according to the WorldNuclear Association (WNA).
