“…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 general, in Mexico there are few studies that assess the concentration of heavy metals in substrates and plants growing in mining waste (Armienta et al, ; Carrillo‐Gonzalez, ; Carrillo‐González and González‐Chávez, ; Díaz‐Villaseñor, ; Flores‐Tavison et al, ; Franco‐Hernández et al, ; Juárez‐Santillan et al, 2010; Prieto‐García et al, ; Puga et al, ; Ruiz and Armienta, ; Santos‐Jallath et al, ), as well as the identification of heavy metals inside plants tissues. These studies allow to observe the presence of metals, becoming evident the accumulation and translocation to different organs of the plant, using tools as optic and scanning microscopy or energy dispersive X‐ray spectrometry (Arias et al, ; Günthardt‐Goerg and Vollenweider, ; Meyers et al, ; Tung and Temple, ; Vieira et al, ; Vollenweider and Günthardt‐Goerg, ; Vollenweider et al, b).…”

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.

“…One of the most promising ways to mitigate the negative influence of sludge/flotation tailings is the application of biological methods. Phytoextraction or phytostabilization can be useful alternatives in waste management and/or extraction of valuable components (Cano-Reséndiz et al 2011;Pourrut et al 2011, Santos-Jallath et al 2012Zhang et al 2014), in which plants can grow on sludge or flotation tailings extremely polluted with heavy metals.…”

The aim of the study was to estimate the ability of ten tree and bush species to tolerate and accumulate Cd, Cu, Pb, Zn, and As species [As(III), As(V), and total organic arsenic] in industrial sewage sludge extremely contaminated with arsenic (almost 27.5 g kg(-1)) in a pot experiment. The premise being that it will then be possible to select the most promising tree/bush species, able to grow in the vicinity of dams where sewage sludge/flotation tailings are used as landfill. Six of the ten tested tree species were able to grow on the sludge. The highest content of total As was observed in Betula pendula roots (30.0 ± 1.3 mg kg(-1) DW), where the dominant As species was the toxic As(V). The highest biomass of Quercus Q1 robur (77.3 § 2.6 g) and Acer platanoides (76.0 § 4.9 g) was observed. A proper planting of selected tree species that are able to thrive on sewage sludge/flotation tailings could be an interesting and promising way to protect dams. By utilizing differences in their root systems and water needs, we will be able to reduce the risk of fatal environmental disasters.

“…Total Arsenic (As) concentrations were higher than those reported by Santos-Jallath et al (2012) at three tailings impoundments from Queretaro, Mexico. 18 These authors found between 1,183-14,600 mg Arsenic (As) kg . 20 Baroni et al (2004) reported total Arsenic (As) concentrations in the range from 5.3 to 2,035 mg kg -1 in two former Sb-mining areas and on an old quarry once used for ochre extraction at the South of Italy.…”

Introduction: Plant metalloid contamination may represent an important pathway of Arsenic (As) intake by humans, wild herbivores and livestock. Objective: This study aimed at estimating Arsenic (As) exposition risks to wild plants naturally growing on the contaminated area of Zimapan, Hidalgo, Mexico. Materials and Methods: Arsenic concentrations in the rhizosphere, aerial and root parts, and deposition on leaves of wild plants from two mine tailings were analyzed. Results: The range of total and EDTA-extractable Arsenic (As) concentrations on the mine tailings were from 4016 to17,178 mg kg -1 and from 234 to 499 mg kg -1, respectively. Eleven plant species were the dominant vegetation. Some of these are important in the folk Mexican medicine. Retention of Arsenic (As) in aerial part was between 49 to 7,521 mg kg .6 and 9.6, respectively). Juniperus sp and Ruta graveolens behaved As excluders, while Dalea bicolor accumulated Arsenic (As) close to the maximum tolerate concentrations to animals. After a very drastic washing procedure, leaves still had structural high Arsenic (As) concentration (49-2, 940 mg kg -1 ). Conclusion: This study highlighted that plants are important organism for retaining Arsenic (As) not only on leaves surface but also structurally. Therefore, they strongly influence Arsenic (As) dispersion and risk from mine tailings. Phytoremediation using some of these plants is suggested taking into account control measures to deplete Arsenic (As) transfer to livestock or medicinal herb use.
