“…However, Sb does not show high variation coefficients, probably due to the low mobility of this element in a semi-arid climate, as shown by Esbrí et al ( 2023 ). Multielemental content data for holm oaks are not abundant in the scientific literature; thus, the works of Higueras et al ( 2016 ) and Monaci et al ( 2022 ) were chosen as a comparison due to their similarities in the study area in physiographic and mineralogical terms. After a comparison of the dataset, in this study only Sb and Hg exceeded the contents published by Monaci et al ( 2022 ), demonstrating the ability of the plant-species to capture Sb through the roots, bioaccumulate, and translocate to the above-ground parts of the plant, in addition to the Hg uptake directly from the atmosphere in gaseous form in an area deeply enriched for these elements, especially for Hg, as it has been commented in the “ Introduction ” section.…”

The soil–plant transfer of trace elements is a complex system in which many factors are involved such as the availability and bioavailability of elements in the soil, climate, pedological parameters, and the essential or toxic character of the elements. The present study proposes the evaluation of the use of multielement contents in vascular plants for prospecting ore deposits of trace elements of strategic interest for Europe. To accomplish this general goal, a study of the soil–plant transfer of major and trace elements using Quercus ilex as a study plant has been developed in the context of two geological domains with very different characteristics in geological terms and in the presence of ore deposits: the Almadén syncline for Hg and the Guadalmez syncline for Sb. The results have made it possible to differentiate geological domains not only in terms of individual elements, but also as a combination of major and trace elements using Factor Analysis. The bioconcentration factors have demonstrated the uptake of macronutrients and micronutrients in very high concentrations but these were barely dependent, or even independent of the concentrations in the soil, in addition to high values of this factor for Sb. The Factor Analysis allowed for the differentiation of geogenic elements from other linked to stibnite ore deposits (Sb, S, and Cu). This element (Sb) can be uptake by Quercus ilex via the root and from there translocating it to the leaves, showing a direct relation between concentrations in soil and plants. This finding opens the possibility of using Quercus ilex leaves for biogeochemical prospecting of geological domains or lithological types of interest to prospect for Sb deposits.

“…The anthropogenic activities, including spills, transferences, and the accumulation of residua, produce elemental changes considered to be contamination. Among them, mining and related activities constitute the most polluting processes, without being the only ones (Higueras et al 2016 ).…”

“…Consequently, they represent the main source of global environmental pollution with noxious implications for human health (Muyessar and Linsheng, 2016). PHEs are naturally present in soils, and some of them are essential micronutrients for plants, however, when concentrations exceed a specific threshold, they may cause toxicity (DalCorso et al 2014;Higueras et al 2016). For instance, high concentrations of PHEs can affect plant nutrition and fitness by displacing other essential nutrients, what may cause deficiencies limiting plant performance (DalCorso et al 2014;Kabata-Pendias 2011).…”

Gypsum mining spoil improves plant emergence and growth in soils polluted with potentially harmful elements

Purpose Soil pollution is a major problem worldwide. Some anthropogenic activities, such as mining, may exceed soil capacity, causing relevant health and ecosystem hazards. The use of mineral amendments can help reduce soil pollution. Gypsum mining spoil (GS) is a waste material highly produced in gypsum mining industry, which has never been used in soil remediation despite its high potential as amendment of polluted soils. In this study, we carried out an ex-situ experiment to assess for the first time the capacity of GS to both reduce the availability of Potentially Harmful Elements (PHEs) in soils and promote seed emergence. Methods Soils affected by residual pollution after the Aznalcóllar mine spill were collected, treated with GS in three different proportions, and sown with seeds of two non-genetically related species. Seed emergence and biomass production were monitored, and PHE content in soils and plants were analysed. Results We have observed a direct and very positive relation between GS and both the reduction of PHE availability and PHE uptake by plants, and the increase of plant emergence and growth, especially with the addition of the highest doses of the amendment. Conclusion This study highlights the promising results of GS as a novel soil amendment to be used in the remediation of polluted soils and vegetation recovery. Moreover, using GS as soil amendment will bring the opportunity to sustainably manage this waste material and reduce its social and environmental impact parallelly to the mitigation of PHE hazards.

“…A discussão acerca da contaminação do ambiente exige um olhar sobre os elementos potencialmente prejudiciais e que causam efeitos sobre os recursos naturais e a saúde da população, sendo que os processos industriais, a mineração, a agricultura intensiva e o descarte incorreto de resíduos fazem parte das principais atividades que geram contaminação do solo e água. 1 Nos Estados Unidos a preocupação com as áreas contaminadas tem ampliado a atuação da Agência de Proteção Ambiental (EPA-USA). A existência de milhares de locais contaminados decorrentes de inúmeras atividades industriais, agrícolas ou de mineração, despertou para a necessidade de rastrear, identificar, monitorar e gerir programas de descontaminação, uma vez que além da questão ambiental é grande o impacto econômico gerado ao país.…”

Recebido em 05/12/2019; aceito em 05/02/2020; publicado na web em 14/04/2020 APPLICATION OF ZERO-VALENT IRON NANOPARTICLES (nZVI) ON THE REMEDIATION OF CONTAMINATED SOIL AND GROUNDWATER: A REVIEW. The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an important element to be used in remediation techniques, in addition to being efficient and low cost. In this article the objective is to present a bibliographic review on nanotechnology applied to soil and groundwater remediation, especially the application of nZVI, considering its main characteristics, reactivity performance, pollutants that can be degraded, application and transport techniques and main advantages and disadvantages. Issues related to toxicity and factors related to in situ applications are also presented. It is considered the results that have been observed, there is feasibility for the research to intensify even more, due to the efficiency of this nanomaterial on pollutants present in soils and waters, and it is important to expand the studies in Brazilian soils, since most of the research is international, and it is not possible to directly transfer knowledge acquired from temperate soils to residual soils of tropical and subtropical climate.
