Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran.
Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For preliminary understanding of soil heavy metals pollution in industrial estates, the concentrations of zinc and copper in the soil are analyzed and investigated to evaluate their concentration and environmental quality based on the contamination factor.
Results: The results indicated the soils had been polluted by heavy metals due to industrial processes that concentrate these metals in the soil. Copper concentrations varied from 15.69 to 49.55 mg/kg. Zinc concentrations were found to be between 23.02 and 144.17 mg/kg. The highest concentration of Zn was found in Arak 3 region which may be due to industrial activities while the highest concentration of Cu was observed in the soil of Arak 1 region that may be due to proximity of this industrial estate to Arak city. The findings of the contamination factor showed that the heavy metals are accumulated in the soil of industrial estates that are considered low risk for contamination with zinc and copper.
Conclusion: The achievements of this research showed the location of the industrial estate, proximity to highways and main roads, and the area of green space of industrial estates are important factors in determining heavy metals concentration.
