“…The exact location (longitudes and latitudes) of each sample point was determined using a global positioning system (GPS) instrument (Garmin Etrex 10 GPS, Garmin Ltd, Lenexa, Kansas, USA). Finally, the soil samples were transferred to the laboratory (Khanlab LLC, Ulaanbaatar, Mongolia) with the sample-box by cab for further analysis [23,24,25].…”

“…I geo was estimated using [27]:Igeo=log2(Cn1.5Bn) where C n is the concentration of an element in urban soil and B n is the background value. In this study, the chemical composition of non-effected soil at a site of each city [18,23,28] was chosen as the background values for calculating the I geo values. The constant 1.5 allowed us to analyze natural fluctuations in the concentration of a given substance in the environment and to detect very small anthropogenic influences [27].…”

Using the case of Ulaanbaatar, Erdenet, and Darkhan cities from Mongolia, the study aimed to assess the contamination level and health risk assessment of heavy metals (As, Cr, Pb, Ni, and Zn) in urban soil. A total of 78 samples was collected from a variety of functional areas. The geoaccumulation index (Igeo) and integrated pollution index (IPI) were used in pollution assessment, while the health risk was scored using a hazard quotient (HQ) and health index (HI) for non-carcinogenic heavy metals, as well as a lifetime average daily dose (LADD) for carcinogenic heavy metals. The results show that the concentration of heavy metals in the soil samples taken from Darkhan city, which presented “uncontaminated” values in terms of Igeo for all metals, was relatively lower than other cities within the contamination assessment. Furthermore, the Igeo value signified “uncontimated to heavily contaminated” soil in the Ulaanbaatar and Erdenet cities. Typically, as for the IPI that observed similar trends with Igeo, the mean IPI values in Ulaanbaatar, Erdenet, and Darkhan were 1.33 (moderate level of pollution), 1.83 (moderate level of pollution), and 0.94 (low level of pollution), respectively. In terms of the assessment of potential health risk, there was a particular or different level of ingestion, dermal contact, and inhalation exposure pathway for human health. Among these three different pathways, the ingestion was estimated by the main contributor for health risk. Each value of HQ and HI indicated that soil heavy metals of studied cities were at a safe level (<1) or had the absence of a significant health risk there. In addition, the potential health risk for children was greater than for adults, where heavy metal values of HI for children had a high value compared to adults. We estimated carcinogenic risks through the inhalation exposure, and as a result, there were no significant risks for human health in the studied cities from three elements (As, Cr, and Ni).

“…This is particular an issue for those surfaces that are unstable due to a dipole moment normal to them in the bulk structure (Tasker's rule) [84] . Surfaces can stabilize themselves for example by surface reconstruction, formation of cation/anion vacancies or the adsorption of molecules from their surroundings [85,86] . So, it is not unlikely to expect a surface termination that has little to do with the bulk of the material.…”

“…Human-made pollution enters into soil, which aquatic ecosystems and increases the amount of PTEs in these environments, leading to many problems for animals and plants. 43,44 The average concentrations of arsenic, cadmium, chromium, copper, lead and zinc in the soils of Eghlid city in southern Iran were 45 Many studies have showed that the concentration of heavy metals in topsoil can vary. 10,11,16,26,45 This difference in concentration of heavy metals may be due to human activities such as industry, agriculture and urbanization.…”

Background: The potentially toxic elements (PTEs) are one of the most dangerous pollutants in the environment. In this study, the elements namely cadmium, lead, chromium, nickel, copper and zinc were investigated in the soil. Methods: In this study, 144 composite samples were randomly prepared from surface soils in a depth of 10 cm in the cities of Shushtar and Dezful. Soil sampling was performed in 12 stations in Shushtar and Dezful. The PTEs were determined by ICP Varian 710-ES device. Results: The pattern of accumulation of PTEs was as Cu>Pb>Cd>Zn>Ni>Cr in Dezful. In Shushtar, the accumulation of metals in the soil was as Cu>Pb>Cd>Ni>Zn>Cr. The concentration of Ni and Cr in the surface soils of Shushtar was higher than Dezful. The Ecological risk of Cd in the surface soils of Dezful and Shushtar was higher than other PTEs. The most important risk factor for carcinogenicity was related to Cr (3.15×10-7) in children. Hazard quotient (HQ) value of studied PTEs for adults and children were obtained by ingestion, inhalation, and dermal contact absorption of less than 1. Conclusion: According to the results, the PTEs of Cd, Pb and Cu caused high pollution in the soils of Shushtar and Dezful, which is due to agricultural, industrial and urban activities in these areas. In general, the metals Cr, Zn and Ni slightly contaminated the soil. Also, the ecological risk of PTEs showed that the highest effects on soil was related to Cd and Pb metals.
