Background and Purpose: In the environment, heavy metals in high concentration are toxic to

most organisms. Human activities have continuously increased the concentration of these metals

in the environment such as soils. In the present study, soil samples collected from Ahvaz IV

industrial estate in Khuzestan Province.

Materials and Methods: The soil samples were taken from 9 stations in 4 cardinal directions at

two distances (300 and 600 m) with three replicates in 2013. Samples subjected to bulk

digestion and chemical partitioning. The concentrations of Fe, Mn, Ni, and Sn in soil were

determined by inductively coupled plasma atomic emission spectroscopy. We used geoaccumulation

index (I-geo) and pollution index (Ipoll) to assessment the soil contamination in

the soil samples. Furthermore, all statistical analyses were performed using the SPSS statistical

package.

Results: I-geo and Ipoll results indicated that the soil samples are unpolluted to moderately

polluted for all metals. The anthropogenic portion of metals are as follows: Fe (93%) > Ni

(84.2%) > Mn (79.5%) > Sn (64%). Furthermore, the percent of anthropogenic pollution was

more than percent of the natural portion.

Conclusion: Metals concentration had the highest rate at a distance of 300 m from the

contaminant of the source. The result of cluster analysis showed that there is strong relationship

among all metals.
