Road traffic and maintenance induce chronic heavy metal pollution in the atmosphere and roadside soil. A portion of these pollutants could be dispersed into the air or deposited onto soils as a result of wind dispersion. The main objective of this research was to determine the level of Pb, Fe, Zn, Ni, Cd, Cr, and Cu in dust samples collected near industrial, residential, commercial and rural streets in the Jamshedpur city during March- April 2023. The concentrations of heavy metals were analyzed using an inductively coupled plasma-mass spectrometer (ICP-MS). The result shows metal concentrations Pb, Fe, Zn, Ni, Cd, Cr, and Cu are varied from 14.08-145.25 ng/m3, 129.30-687.09ng/m3, 51.21-302.01 ng/m3, 10.08-31.09 ng/m3, 29.52-165.28 ng/m3, 18.25-68.38 ng/m3 and 19.39-64.01 ng/m3 respectively. Overall, the rank of risk contribution to the local environments among the six heavy metals was Fe (375.54) > Zn (180.21) > Cd (98.48) > Pb (76.54) > Cu (41.48) > Cr (40.86) > Ni (18.90). These values were compared with results from various cities/countries world-wide. This study suggests that earth crust and anthropogenic activities such as motor vehicles were the main sources of heavy metal contamination in the study areas.
