Total Suspended particulate matter (TSP) inurban atmosphere of Bandar Abbas was collected using a high volume sampling technique for a period of one year (2010-2011). The nitric acid–perchloric acid extraction method was used and the metal contents were estimated byatomic absorption spectrophotometer. The highest mean concentration was found for Ni at 34.5 μg/m3 followed by Fe (44 μg/m3) in hot season and 33 μg/m3 and 34 μg/m3 in cool season and there were more than WHO and USEPA standards. However, the average Ni level (0.033μg/m3) was 6.7 times higher than the proposed WHO standard.On an average basis, the decreasingmetal concentration trend was: Fe>Al>Cd>Pb>Ni. The correlation study revealed very strong correlations (P<0.01) between Pb-Ni, Fe-Al and Cd-Pb. Finally, suitable managing solutions to improve existing situation is presented in term for all results.
