“…OM is very low in the distances from 0 to 100 m and low in the distances of 1000-10,000 m in accordance with Mexican regulations (NOM-021- SEMARNAT-2000). OM values found were comparable with other studies [50,55,56] done in the area ranging from 1.2 to 11.6%. Organic matter is formed by humic acids that provide a broad cation exchange capacity [60]; the interaction between organic matter and clays can improve soil adsorption capacity of inorganic contaminants [61].…”

“…According to Mexican regulations (NOM-021-SEMARNAT-2000), pH levels in soils in zones 0 and 10 m can be considered as strongly acidic and moderately acidic, respectively; while for distances from 1000 to 10,000 m, soil can be considered neutral. The pH values found were lower than those in other studies [50,55,56] for the area ranging from 7.1 to 8.2%, which may be due to the technique of pH determination or the selection of sampling points. pH is one of the most important parameters that control the change of the chemical forms of the elements in soil [57].…”

“…An increase of the EC was found mainly between the distances of 0-100 and the distances of 1000-10,000 m (kW-H 4,25 = 21.06, p = 0.0003, Figure 4b). EC levels can be considered as negligible effects of salinity for all sites in accordance with The EC values found in this study were low with respect to other studies [50,55,56] done in the area ranging from 2200 to 12,200 μS/m; the differences could be due to the technique of determining EC or the selection of sampling points. A high EC could facilitate the mobility and bioavailability of metals in the soil through two possible means: (1) positively charged ions associated with salts (Na and K) that can replace heavy metals in the absorption sites and (2) negatively charged ions (for example chlorides) which can form stable soluble compounds with heavy metals (Cd, Zn and Hg), and have a tendency to generate acidic soils [59], as could be the case of the first 100 gradient meters.…”

“…Another property that must be considered is organic matter because they can form complexes with heavy metals and enzymes and in this way reduce their toxicity. Martínez-Toledo et al [50] found an increase in several enzymes directly associated with pH and OM content in mining sites of San Luis Potosí.

“…In Villa de la Paz, Martínez-Toledo et al [50] found values (mg/kg) of As from 1461.9 to 28274.0 and of Pb from 466.1 to 3486.4 in a site close to the source of contamination. In another study, Márquez-Reyes [51] determined the average total concentrations (mg/kg) of 13,443.4 of As and 1301.7 of Pb.…”

The mining industry has generated different sources of pollution and effects in human and ecosystem health. The objective of this study was to evaluate the effect in gradient of the biological activity of the soil derived from the contamination by lead and arsenic. A linear transect was conducted from the tailings in Villa de la Paz to a reference site 10 km away against wind direction and runoff. The parameters that were analyzed in the soil samples included As, Pb, pH, organic matter, electrical conductivity, soil respiration, and soil enzymes. As concentrations ranged from 4.7 to 463.2 mg/kg, while those of lead ranged from 171.7 to 2319.0 mg/kg. The changes in the physicochemical parameters and in the biological activity of the soil were stronger within the first 100 m of distance from the tailings. The pattern of inhibition of biological activity was: urease>β-glucosidase>arylsulfatase> dehydrogenase>phosphatase>respiration. Strong negative relationships were observed among biological activities and arsenic (from 86.5 to 96%). Metals and covariables jointly explain the 89.2% of variability of the effect in the biological activities. This study provides a field baseline that could be part of a long-term monitoring and remediation program.

The purpose of this study was to evaluate the effects of potentially toxic elements (PTEs) on soil microbial community functionality and structure. Charcas and Cedral in San Luis Potosí, Mexico, are sites with ancient mining activity. This activity has generated heavy metals (HMs) polluted soils that provoke deleterious effects on microbial community. Sampling was conducted in sites with and without aged mining activity. The parameters analysed were physicochemical properties and PTE concentrations. Functional diversity was evaluated with a community‐level physiological profiling (CLPP) analysis, diversity was evaluated using the richness (S), and the indices of Shannon's diversity (H), Simpson's dominance (D) and Pielou's evenness (J) were for the structure evaluation, based on relative substrate utilisation. CLPP results of set of soils indicated the following substrate utilisation pattern: carbohydrates > polymers (POL) > carboxylic/ketonic acids > amino acids (AmA) > amine/amides (A/A). In Cedral, the AmA utilisation favoured the increase of J value. In addition, it was observed that the utilisation of these compounds decreases at a higher concentration of Al and organic matter (OM) but increases at a higher concentration of Cu, Pb, Zn, Fe, Mn, and Ni, a phenomenon opposite to that was observed in Charcas. The results of set of soil indicated that AmA utilisation increases the values of S, J, D, and H. These results indicate that the microorganisms in soil are resistant to high PTE concentrations, in that condition they need accessible carbon sources as energy and as nutrients, however, they adapted to use complex carbon sources (POL). Furthermore, it presented low OM mineralisation despite high values of H, or J, then some metabolic processes could be compromised. Therefore, an intervention for soil conservation and monitoring is required.
