“…Therefore, Miscanthus planting could help to improve the soil organic matter and soil properties. Miscanthus planting accompanied by biochar and biosolid application, significantly enhanced the abundance of humus and mycorrhizal fungi, and improves soil fertility and hydraulic properties, with biosolid exerting the most pronounced effect among them (Allami et al., 2019).…”

“…Plant colonization and soil quality of mine-affected areas may be ameliorated through the application of amendments, by the use of tolerant plant varieties, and/or by the application of microbial inoculants (Wang et al, 2017). The addition of organic and/or inorganic amendments to mine wastes has been a strategy widely used to promote adequate conditions for plant growth (Acosta et al, 2018;Al-Lami et al, 2019;Saleem et al, 2020a). These amendments not only diminish metal availability, but also provide nutrients for plant growth and improve soil microbial activity (Lwin et al 2018).…”

“…The addition of organic and/or inorganic additives to mine soils, or even tailings, has been a widely used strategy to promote suitable conditions for plant growth, coping with their main constraints, by adding essential nutrients and organic matter, reducing the acidity, increasing the water holding capacity, and making PTEs less mobile or bioavailable, increasing their association with organic matter, carbonates or metal oxides [109,127,129,152,175,186,[199][200][201][202]. The improvement in these soil properties is of major importance, not only to promote plant growth, but also to increase soil microbial activity [28,[203][204][205].…”

Potentially Toxic Elements’ Contamination of Soils Affected by Mining Activities in the Portuguese Sector of the Iberian Pyrite Belt and Optional Remediation Actions: A Review

et al. 2022

Both sectors of the Iberian Pyrite Belt, Portuguese and Spanish, have been exploited since ancient times, but more intensively during and after the second half of the 19th century. Large volumes of polymetallic sulfide ore were extracted in open pits or in underground works, processed without environmental concerns, and the generated waste rocks and tailings were simply deposited in the area. Many of these mining sites were abandoned for years under the action of erosive agents, leading to the spread of trace elements and the contamination of soils, waters and sediments. Some of these mine sites have been submitted to rehabilitation actions, mostly using constructive techniques to dig and contain the contaminated tailings and other waste materials, but the remaining soil still needs to be treated with the best available techniques to recover its ecosystem functions. Besides the degraded physical structure and poor nutritional status of these soils, they have common characteristics, as a consequence of the pyrite oxidation and acid drainage produced, such as a high concentration of trace elements and low pH, which must be considered in the remediation plans. This manuscript aims to review the results from studies which have already covered these topics in the Iberian Pyrite Belt, especially in its Portuguese sector, considering: (i) soils’ physicochemical characteristics; (ii) potentially toxic trace elements’ concentration; and (iii) sustainable remediation technologies to cope with this type of soil contamination. Phytostabilization, after the amelioration of the soil’s properties with organic and inorganic amendments, was investigated at the lab and field scale by several authors, and their results were also considered.
