Abstract:
Ahwaz is typical of a polluted city. It ranks in the third place after Tehran and Esfahan and with the onslaught Of the dust storms it has acquired the dubious distinction of 1st polluted city in the world. The pollution status of this city was investigated from May 2012 to May 2013. 110 air filters were collected during this period. The air filters were analysed with AAS and INAA techniques. with the use of AAS we measured the concentration of Cd, Cu, Fe, Mg, Mn, Ni and Pb elements. For the use of INAA method on the air filters we used two reactors of MNSR at Esfahan and the 5MW research reactor of Tehran. We managed to measure twenty five elements of Al , As , Br , Ca , Ce , Cl , Co , Cr , Cs , Cu , Eu , Fe , La , Lu , Mg , Mn , Na , Sb , Sc , Sm , Th , Ti , V , Yb , Zn both qualitatively and quantitatively. The results of the analysis showed that in general the crustal element concentration during the dust storms increased by nearly 100% and the other industrial and traffic related elements were not affected to a large extent
