AB  - The high rate of urbanization in Baghdad City is associated with environmental degradation such as
air pollution. In the present study, atmospheric samples of suspended particles were collected using low volume
air sampler (Sniffer) at 18 selected locations in Baghdad City during the period from October 2017 to January
2018. Dust samples collected on fiberglass filter were analyzed for Zinc (Zn), Cupper (Cu), Chromium (Cr), lead
(Pb) and Cadmium (Cd) using flame atomic absorption spectrophotometer model AA-6200. The average total
suspended particles concentration estimated for urban areas (518.38 &mu;g/m<sup>3</sup>) was about 9 times higher than the
value estimated for suburban/agricultural areas (57 &mu;g/m<sup>3</sup>). The ranges of heavy metal concentrations in the
investigated areas were ranged from 8.76-29 &mu;g/m<sup>3</sup> for Zn, 0.014-0.142 &mu;g/m<sup>3</sup> for Cu, 0.31-2.923 &mu;g/m<sup>3</sup>
for Cr, 0.09-1.3 &mu;g/m<sup>3</sup> for Pb and 0.38-1.656 &mu;g/m<sup>3</sup> for Cd. Average levels of Cr (1.51 &mu;g/m<sup>3</sup>) and Pb (0.59 &mu;g/m<sup>3</sup>)
show higher levels than corresponding international limits (0.04 and 0.5 &mu;g/m<sup>3</sup>, respectively). The estimated
Hazard index value for all studied metals (1.5) was higher than the safe level (1), indicating that some
investigated heavy metals reach levels of public health concern.
