“…In this case, 73.91% of the sampled sites were considered moderate ecological risks attributed to the toxicity of metals released by anthropogenic activities such as industrial processes, agricultural practices, and natural sources (Mendoza et al, 2020). Our results are consistent with Suresh et al, 2012;Mohseni-Bandpei et al, 2017;Rehmana et al, 2018;da Silva et al, 2016;Mendoza et al, 2020). It had reported that Cd contributes significantly to the potential ecological risk index of the environment (Luo et al, 2012).…”

Forty-six samples of urban topsoil were collected from Tripoli at a depth of 0–15 cm to determine the concentration of nine heavy metals, including Cd, Pb, Zn, Cu, Ni, Co, Fe, Mn, and Cr. The study aimed to quantify and identify their likely sources of environmental contamination indices and assess their ecological risk to humans. The mean concentrations of these metals were 3.943, 38.317, 170.941, 29.669, 19.699, 30.371, 27444.515, 235.812, and 195.92 mg.kg-1, respectively. These values are higher than the virgin soil background values and permissible limits set forth by WHO. The pollution index (PI) varied from 1.152 for Ni and 2.518 for Cr. The geoaccumulation index (Igeo) averaged 0.824 for Mn and 1.679 for Cr, the contamination factor (CF) averaged 1.28 for Mn and 2.686 for Cr, and the enrichment factor (EF) averaged 0.968 for Mn and 1.893 for Cr, respectively. Pollution indicators such as the Pollution Load Index (PLI), Contamination Degree (Cdeg), and Potential Ecological Risk (RI) suggest that the research region is moderately contaminated, with values ranging from 1.233–1.923, 12.099–18.469, and 47.241–145.067, respectively. Principal component analysis (PCA), correlation coefficient, and hierarchical cluster analysis (HCA) had used to identify the studied metals' possible sources. The results revealed that three sources of heavy metals were determined as indicated by a strong positive correlation between Cd, Pb, Cu, Cr, and Co, which suggested that the sources of these metals are mainly anthropogenic, such as agricultural practices, industrial activities, and vehicle emissions. While the possible sources of Mn, Fe, and Ni mainly originate from natural sources (parent rocks). The heavy metals' potential ecological risk was determined to be moderate. The RI ranged from 65 to 130.

“…For the HMs content, As, Cd, Cr, and Ni were found to be varied from 4.05 to 29.89 mg/kg, 1.19 to 3.7 mg/kg, 257.25 to 3263.87 mg/kg, and 38.89 to 906.70 mg/ kg, respectively, with Cr, had the highest levels of concentrations followed by Ni, As and Cd. The total content of As, Cr, TOC, and Ni in the studied area had a great degree of variability, indicated by a substantial coefficient of variation (CV) values of 55.52%, Intervention Values, 2000), which has been widely used in heavy metals studies (Rudzi et al, 2018;Mohseni-Bandpei et al, 2017;Wu et al, 2018) and the 95% 'Investigation Levels' determined for Malaysia soil (Zarcinas et al, 2004), were also presented in Table 3. The levels of Cd, Cr, and Ni in the surface soil of the mining region were found to be greater than those values.…”

Heavy metals contamination in soil is one of the global issues, posing a threat not just to the environment but also to human health. Identifying the source and distribution of heavy metal pollutants around mining areas can provide a scientific basis for future environmental control. Distributions of the heavy metals (Cd, Cr, As, and Ni) in this study were evaluated using descriptive and multivariate statistics and further described using a geostatistical approach and pollution indices. The total content of Cr, Cd, and Ni in surface soil was observed with a higher concentration level according to the Dutch target values and the 95% Investigation Levels determined for Malaysia soil. Statistical analyses, geostatistics, and GIS mapping suggested that Cd, Cr, and Ni were derived mainly from anthropogenic sources, including mining and agricultural activities, while As could be derived from lithogenic and anthropogenic sources. Geoaccumulation index analysis demonstrated that the contamination that occurred with Cd posed the greatest risk of contamination, followed by Cr, Ni, and As. A spatial interpolated map showed a higher concentration of heavy metals in the vicinity of the mining area. These findings highlight the effectiveness of principal component analysis, geostatistics, and geospatial analyses in evaluating heavy metal contents in the study area. The obtained results could be used by authorities to identify areas requiring remediation management and establish scientific baseline data related to soil quality.

“…The contamination of groundwater is one of the most important environmental issues in the world [4] , [5] , [6] , [7] , [8] , [9] . Among the various pollutants that affect water resources, pollutants containing heavy metals are particularly important due to their high toxicity, even at low concentrations [10] , [11] , [12] , [13] . The parameters in the experiments of this research are including pH, TDS, EC, temperature and heavy metals (As, Hg, Pb, and Cd), in both season of winter and summer.…”

The purpose of this study is zoning and determining the concentration of heavy metals including Arsenic (As), Mercury (Hg), Lead (Pb), and Cadmium (Cd) in the groundwater resources of villages located around the Anzali International Wetland. The amount of heavy metals (As, Hg, Pb, and Cd) in the collected samples were determined by the Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) technique. The maximum concentrations of As, Hg, Pb and Cd were 0.216, 0.059, 0.090 and 0.006 mg/L, respectively.
