“…The plant tissues were rinsed thoroughly using tap water and then washed three times with deionized water to remove the adhered particulate matter (Luo et al, 2017). After manually removing foreign materials, such as stones, plant and animal residues, and plastic pieces, the collected soils were stored in cloth bags for further treatment (Montofre et al, 2021). The plant and soil samples were lyophilized and then pulverized using an agate mortar to obtain fine powders for the chemical analysis.…”

A field experiment was conducted to evaluate the environmental risk of phytoextraction of Cd, Cu, and Pb using Sedum alfredii Hance. with different intercropping patterns. Three receptors representing invertebrates (earthworms), avians (yellow‐feathered chickens), and small mammalian omnivores (Rattus losea) were selected as the potentially impacted environmental receptors. Soil deglutition and food ingestion are considered dominant pathways of metal exposure. Different planting patterns, including S. alfredii monoculture and S. alfredii intercropped (coordinate and malposed) with Cicer arietinum L., were used to evaluate the mobilization, absorption, and migration of Cd during phytoextraction. This study revealed that the intercropping systems, particularly the malposed intercropping patterns, significantly increased the Cd decontamination efficiency by 31.3% and enhanced the content of Cu and Pb in the aboveground tissues of the intercropped C. arietinum. Correspondingly, different planting patterns resulted in varying environmental risks. For the omnivores, which primarily consume earthworms and plant tissues, the hazard index was 0.096 for the S. alfredii monoculture, and the index decreased to 0.074 and 0.090 in the coordinate and malposed intercropping patterns, respectively. The environmental risk might be induced by the increased Cd concentrations in the roots and shoots of S. alfredii. When extrapolating the results of this treatment to the entire region, all the environmental hazard index values of the receptors were higher than 1.0. This study suggests that if a phytoextraction method is used for metal decontamination, corresponding prevention strategies should be established to prevent the diffusion of concentrated metals to higher trophic levels via the food chain.

“…Metal mining produces a large amount of waste with a high concentration of metals and arsenic, that can be mobilized into the environment during the exploitation period and after ceasing mining activities (Cappuyns et al, 2006). These potential toxic elements could be released into the environment through weathering and leaching processes, becoming an important source of environmental pollution (Gonzalez-Fernandez et al, 2011;Montofré et al, 2021). The mobility of metal(loid)s depends on several factors such as pH, redox potential, amount of organic matter and ion exchange processes (Filgueiras et al, 2004), which can occur on the surface of waste dumps, ponds, and slag heaps, representing the most persistent environmental impact from the mining industry (Gundersen et al, 2001).…”

The objective of this study was to evaluate the level of pollution, sources and potential risk of heavy metals (Zn, Cu, Mn, Cd, Cr, Ni, Fe and Pb) and arsenic (As) in four dry riverbeds affected by mine tailing, which drain into one of the biggest coastal lagoon of Europe (Mar Menor). El Beal, La Carrasquilla, Las Matildes and Ponce dry riverbeds sediments were sampled along its course (20, 18, 13, 19 samples were collected, respectively), and total/soluble metal(loid)s, water soluble ions, nitrogen, and organic/inorganic carbon contents were analyzed. Spatial distribution, principal component analysis (PCA), hierarchical cluster analysis (HCA), contamination factor (Cf), pollution load index (PLI) and potential ecological risk index (RI) were used to identify the possible sources of metal(loid)s and to assess the sediment pollution status. The results showed that the mean total concentrations of As, Cu, Cd, Mn, Zn and Pb exceeded the natural background levels of the study area, with the highest values located close to the mining areas. Correlation and cluster analysis identified that Cd and Zn were associated mainly with anthropogenic activities for all riverbeds, while Cr and Ni come from parent. PLI graded the four riverbeds as contaminated by heavy metals, while RI manifested that 100% of samples located in El Beal, La Carrasquilla and Las Matildes had a significantly high ecological risk. Therefore, this study suggests that mine wastes are the main source of metal(loids) contamination in the dry riverbeds, which results can be used to design actions and measures to reduce the environmental impact of metal(loid)s in the Mar Menor coastal lagoon.
