“…These parameters will be helpful for comparing datasets, and subsequently summarizing the obtained results and facilitating its consequent interpretations (Burgos et al 2005;Cai et al 2012;Martínez et al 2007). Figure 3 shows the histogram of the metals Pb, Ni, Se, Mo, and Zn.…”

“…In order to select chemical elements that have been enriched in the Sarcheshmeh copper mine area soils, enrichment factor (EF) was calculated (Bourennane et al 2010;Li and Feng 2012;Martínez et al 2007). It was widely employed to identify the anthropogenic source of metallic elements (Li and Feng 2012).…”

“…This explains why GB defined by Hawkes and Webb (1962) as ''the normal abundance of a chemical element in barren earth material'' has become crucial in environmental studies. It was introduced to differentiate between normal and abnormal element concentration (Martínez et al 2007). Exploratory Data Analysis (EDA) has been recommended as an effective tool to determine the GB (Zhou and Xia 2010).…”

Studying the distribution of metals in the soil of mineral regions is one of the most important environmental issues. These metals are transferred to the cycle of nature by geogenic and anthropogenic resources, causing serious short-and long-term effects, and posing serious risks for the survival of living organisms. Various mining activities, smelting and beneficiation processes are important anthropogenic factors in the presence of metals in soil, which play a far more effective role in soil pollution than natural factors. Sarcheshmeh copper mine in Kerman is one of the largest copper sulfide mines in the world, for which evaluation and grading of metals contamination has paramount importance due to the high volume of mining. In this study, in order to determine the metal content in the surface soil from the Sarcheshmeh copper complex soils area, 120 surface soil samples were taken from a depth of 30 cm, and analyzed for the metals Pb, Ni, Se, Mo and Zn using the ICP-MS method. Then, the contamination coefficient, enrichment factor and geoaccumulation index of these metals were calculated. Based on expert views on the relative importance of each of the indicators and their final weight, risk assessment and grading by the simple additive weighting (SAW) method was performed. According to the results, the highest risk of pollution was obtained for nickel and the lowest was for selenium.

“…This highlights the need of establishing reference values in mining districts to properly evaluate possible environmental disturbances (e.g. Martínez et al, 2007), in soils, sediments, surficial waters, aquifers, dust, etc. In environmental studies, the reference values that constitute the geochemical baseline are commonly the result of a combination between anthropogenic and geogenic contributions in surficial A multi-elemental study to establish the natural background and geochemical anomalies in rocks from the Sonora river upper basin, NW Mexico environments (Salminen and Gregorauskiene, 2000;Reimann and Garrett, 2005). Likewise, the term natural background has been coined to represent the geogenic end-member, which reflects the geochemical composition due to natural processes uninfluenced by human activities (Reimann and Garrett, 2005).…”

Growing industrialization, including mining activity, dramatically increases environmental pollution. Exploitation of natural resources triggers landscape alteration, inputs of potentially toxic chemical elements to the environment and health diseases. In the case of mining activity, the measure of any associated environmental disturbance requires a geochemical background as a reference frame. Since in Mexico, there is a lack of this type of references in mining districts, the present study took a recent mining spill as an opportunity to establish the geochemical background of the upper Sonora river basin, which includes active and historical mining areas. The weighted average of elemental values was calculated using GIS tools. The data show that rocks have a similar geochemical behavior, which is characterized by pristine enrichment of Mn, Ca, P, Ba, Zn, As, Ag, Sb, W, Pb and Bi relative to the upper continental crust. Coefficients of variation values reveal that Sc, Y, Zr, Ce, Yb, Fe, Ti and Al display a conservative behavior and, therefore, they are recommended to be used as reference elements in environmental studies in the basin. The findings of this work highlight the need of determining the geochemical background in mining regions to reach more realistic environmental assessments.Key words: geochemical background; conservative reference elements; Sonora river upper basin; mining district, Mexico.
