In the present study, the potential adverse effects of heavy metals in the soil of Ahvaz oil field were evaluated. 9 soil samples were collected and chemical digestion was performed. Global standard methods was used to collect samples and measure metals. Heavy metals Ni, Cd, Pb, Zn, Cu were measured. and geochemical indicators were evaluated. Average concentrations of heavy metals in soil samples were Cd 0.16, Pb 16.63, Zn 22.03, Cu 10.39, Ni 62.97 ppm. The igeo index findings demonstrated that the values for the metals Ni, Cd, Pb, Zn, and Cu were at an uncontaminated level. TRI index values of metals were Moderate. EF of Cd and Ni wer moderate. CF index of Pb is considerable and cf of Cd and Ni and Zn were moderate. The results of CD, MCD, PLI indicators showed that heavy metals in the studied soils are at the level of contamination. The amount of this contamination was moderate to considerable. The ecological risk of these metals was considerable.
