“…This illustrates that the soils located within about 100 m from the mining dam edge still contained the signature of a metal enrichment and, therefore, that the uncontaminated samples do not truly represent the background soils conditions at a large scale. Total Zn and As concentrations in contaminated soils peak to about 7000 mg kg −1 for both elements, in agreement with reported values for those locations (Duarte-Zaragoza et al, 2015;Morton-Bermea et al, 2013;Santos-Jallath, Coria-Camarillo, Huezo-Casillas, & Rodríguez-Cruz, 2013).…”

Isotopically exchangeable metals in soil, also termed labile metals, are reversibly bound to soil surface and are a better index of the environmental risk of the metals than are their total concentrations. In this study, labile fractions of potentially toxic elements were surveyed in metal mining‐impacted soils of Mexico to test the relative importance of soil properties (pH, effective cation exchange capacity, organic matter, etc.) or attributes of the mines (ore type and lithology, metal mineralogy, etc.) on the fractions of labile elements. Mining waste‐impacted soils, corresponding uncontaminated soils and mining waste were collected around 11 metal mines in Mexico presenting contrasting ore types. Pseudo‐total concentrations and labile fractions of Cd, Ni, Zn, Pb, Cu, and As were determined by aqua regia digestion and isotope dilution, respectively. Pseudo‐total concentrations of these elements ranked: waste > contaminated soil > uncontaminated soils, and Zn and As dominated the concentrations of toxic elements. The labile fractions (% of total) in the soils ranked, with median values in brackets, Pb (22) > Cd (18) > Cu(15) > Ni∼Zn(13) > As(9). The labile fractions of waste samples were slightly higher than those of soil samples suggesting either a high weathering of mining wastes or the stabilization of heavy metals by soil. Stepwise multiple regression showed that soil properties rather than source attributes primarily explained the %E of most elements, except for Zn and As for which the ore lithology was the dominant factor. This study showed that earlier generic models explain metal lability adequately in mining waste‐impacted soils.

“…The control zone was in the normal concentration range for soil for the following elements: Pb, Zn, Cu, Cd (2–300, 1–900, 2–250, and 0.01–2.0 mg kg −1 , respectively) according to Alloway () and As (0.1–40 mg kg −1 ) according to Bowen (), it was therefore considered suitable to be taken for comparison with the other polluted sites. Comparing our data with other studies (Armienta et al, ; Franco‐Hernández et al, ; Morton‐Bermea et al, ; Ruíz and Armienta, 2012; Santos‐Jallath et al, ), it is clear that metal concentrations in the mining waste vary widely, which is associated with mining and smelting operations as well as the type of mineral resources (Bradshaw, ). Based on the results, it can be observed that the soils are a source of contamination that could affect the development of organisms that grow and live on them.…”

In this article a study of the distribution of heavy metals in Cupressus lindleyi breaching-leaves was done in Taxco, Guerrero. At the same, heavy metals micro-localization was conducted in the breaching-leaves to understand the structural changes provoked by mining waste on plants. The most abundant contaminants in soils, tailings and different plant organs (roots, stems, and leaves) were Zn, Mn, and Pb. Nevertheless, As was more accumulated in the stem and breaching-leaves. The translocation factor and the bio-concentration factor were less than 1. The structural changes observed were the great accumulation of starch grains and phenolic compounds in the palisade parenchyma, changes in the hypodermis cell wall and necrotic zones in the palisade parenchyma. The distribution of heavy metals in breaching-leaves tissues was homogeneous in most of the elements. These results showed that C. lindleyi is a species that can be employed in phytostabilization of contaminated zones with mining waste because it is a native plant that does not require a lot of conditions for its development.

“…In this study, the concentration of Zn was found to be higher than that reported by Morton et al . . The maximum values allowed for wetland soils by Mexican Standard NOM‐147‐SEMARNAT/SSA1–2004 were exceeded (Pb = 400 ppm and As = 22 ppm).…”

“…The contaminated area for the current study was chosen based on previous studies performed in that mining site and that have focused primarily on the geochemical behavior of heavy metals (Pb, Zn, Cu, Mn, and Fe) and As . This study was carried out with the following aims: (1) to identify plant species that develop naturally in a semi‐permanent wetland and (2) to assess the tolerance and accumulation of heavy metals and As in plant tissues for further consideration in phytostabilization in areas with similar characteristics.…”

The total concentration of Pb, Zn, Cu, Fe, Mn, and As in mining‐impacted soils and pioneer plants from a semi‐permanent natural wetland was determined by X‐ray fluorescence. Results showed that the maximum values in soil were Fe > Zn > Pb > Mn > As > Cu and in plants were Zn > Pb > As > Cu, and Mn and Fe were found in variable concentrations. Bouteloa repens showed the highest translocation factor (TF) for all heavy metals, and the highest phytoavailability index (PI) for Fe, Cu, As, and Mn. However, Typha dominguensis was the plant species with the most elevated bioconcentration factor (BCF) for Mn and Fe and PI for Pb and Zn, while Cyperus manimae showed the maximum BCF for As, Pb, and Cu, and the highest PI for Mn. For Eleocharis ovata the maximum BCF and PI were for Zn and As, respectively. The PI indicates the availability of heavy metals and As in the environment and their bioaccumulation in plants. The plant species reported in this study are pioneer plants that can easily become established due to their environmental resilience and physiologic characteristics. This study shows that B. repens and T. dominguensis are species that translocate heavy metals and accumulate them in their various organs, and therefore, these plants are suggested as good candidates for phytostabilization in similar semi‐permanent natural wetlands. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 980–988, 2018
