Abstract

Background and Objective: HEAVY METALS are the most frequent pollutants of urban soils. In general, human health and especially children are directly at risk if the soil is being accidentally ingested orally or nasally. Therefore, this study was conducted to assess potential ECOLOGICAL RISK index (RI) of Pb, Cd, Cr and Cu in SURFACE SOILs of URBAN PARKS in TEHRAN City in 2016.Materials and Methods: A total of 60 SURFACE SOIL samples were collected from Mellat, Laleh, Velayat, Ekbatan and Pirouzi parks. The HEAVY METALS contents in samples were determined using ICP-OES after acid digestion of soil samples. Also, RI of HEAVY METALS was determined. All statistical analyses were performed according to the Shapiro-Wilk test, One-Way ANOVA, One Sample T-Test and Pearson Correlation Coefficient.Results: The lowest and highest contents of the metals (mg/kg) with an average of 0.52 ± 0.25 and 153.81 ± 31.83 were related to Cd and Pb, respectively. Pb and Cu were higher than MPL. Also, the highest SURFACE SOIL contamination was related to Velayat Park located at the south of TEHRAN. The value of RI was 99.16 and therefore the soil contamination was categorized in low ECOLOGICAL RISK.Conclusion: Although the value of RI categorized as low ECOLOGICAL RISK, due to mean concentrations of Pb and Cu were higher than MPL, control of soil-contamination sources, periodic monitoring of SURFACE SOIL in the URBAN PARKS where citizens spend most of their free time. Additionally, it should be avoided to construct URBAN PARKS close to the regions with high traffic intensity.
