Abstract :

This research was conducted to determine levels of heavy metals pollution in air near nuclear power plant I Tehran-Iran. Concentration of heavy metal (lead & cadmium) has been measured and analyzed in different seasons. Air sampling was done by HI-VI (High Volume Sampler) in different seasons. The preparation of heavy metal samples were determined by atomic absorption spectrophotometry. The results were analyzed by Spss software. Results showed average concentration of Pb and Cd was 0.41، 0.04 μ g/m3 respectively in the second half of the year that were below than the standards (1.5، 0.15 g/m3μ). The results confirm that the concentration of heavy metals (lead and cadmium) depends on the circumstances especially precipitation and air turbulence which were reduced during precipitation، also in inversion situation concentration of heavy metals increases because of being lower than international standard even in inversion situation.
