Due to the rapid population growth, advanced technology and continued urbanization worldwide, heavy metals are emitted into the ecosystem and cause negative impacts on health. This study represents the determination of street dust heavy metals copper (Cu), lead (Pb), zinc (Zn), cadmium (Cd), nickel (Ni) and chromium (Cr) in thirty sites in Babylon governorate, Iraq and investigates the possible sources of the pollution. The analysis was carried out by using flame atomic absorption spectrophotometer after the digestion process. The average concentration of Cu, Pb, Zn, Cd, Ni and Cr in the street dust were found to be 130.9, 201.4, 253.3, 2.2, 49.1 and 69.1 mg/kg, respectively. After performing a comparison with the mean of worldwide scale and values for uncontaminated soil, the findings indicated that there were high heavy metals concentrations in all sites. The main cause is the increased traffic across all areas which makes the vehicles disposed of different elements in the street dust. Moreover, the absence of regulation and lack of basic sewer and rain networks play a significant role to increase the heavy metals concentrations in the city. This research promotes a baseline data for heavy metals pollution in Babylon street dust which could afford to policymakers in order to adopt urgent environmental management strategies such as increasing green area and implementing new technologies to reduce environmental risks.
