“…However, no studies of iron uptake by crops has been carried out in the nearby intensive agricultural lands. Furthermore, if these results are compared with the soil map (Ramírez et al, 1999), the soil type present in the agricultural region (Haplic Calcisol) cannot give rise to such elevated levels of iron oxides, which may be indicating a potentially hazardous situation for crops (Elberling et al, 2010; Jordán‐Vidal et al, 2020).…”

Torrential rainfall regimes, among others, are the origin of accelerated soil erosion. The Spanish southeastern Mediterranean region is characterised by an arid climate regime affected by extreme erosion episodes with an important loss of sediments. Soil erosion effects are even more noticeable in areas where soil has been anthropically degraded, as in the mining district of Sierra Minera de Cartagena. The present research focuses on monitoring and mapping the changes in the sediment distribution of iron oxides and hydroxyl (OH−) bearing minerals caused by a cold drop known in Spanish as 'DANA' in September 2019 on the Rambla del Beal. This short rambla is fed by sediments from its drainage basin and by mining residues, irrigating a wide agricultural area. When discharges overflow the rambla channel, residues spread over its floodplain and reach the ecological protected coastal lagoon Mar Menor. The objective of the study was mapping the mineral distribution of the mining materials eroded from the source areas and sedimented in Rambla del Beal during a DANA. The study was carried out using a pre‐ and a post‐DANA image from the Sentinel‐2 satellite. After masking vegetation, urban areas and water bodies, different band ratios (B4/B3, B11/B12, B8A/B6) and a Spectral Angle Mapper (SAM) classification were applied. Sediment deposits were identified in wider areas after the DANA. Iron oxides increased their extension by 11.08% in the central area (B3/B4 with R2 of 0.84) and hydroxyl‐bearing minerals increased by 8.95% in the Rambla del Beal's headwaters (B11/B12 with R2 of 0.71). The SAM classification (with a 0.1 rad threshold and an overall accuracy of 87.33%) allowed the differentiation and classification of two ferric iron oxides (haematite and goethite) and one iron hydrous sulphate mineral (jarosite). Additionally, band ratio images were spatially overlaid with the soil land uses map layer of the cadastre in order to plot the land uses most affected by the transported sediments during the DANA. These results highlighted agricultural land as the areas (land uses) most affected by iron oxides deposition, as oxidation processes occur more rapidly in these areas. However, grassland and scrubland were the areas with the highest content of hydroxyl‐bearing minerals, as water is accumulated in these places, which favours hydrolysis reactions. Highlights Torrential events can relocate large volumes of contaminated sediments from former mining areas. Sentinel‐2 allows monitoring mine waste iron‐sulphate changes caused by weathering alteration. Spatial mineralogical pattern in sediments is controlled by geomorphology and flood dynamics. The proposed digital image analysis allows mapping short‐term evolution of mine waste sediments.

“…Soil quality can be analyzed and assessed using several scales with different analysis objectives, information requirements, soil data, implications, and consequences for an appropriate management of soil functions [57,58]. Karlen et al [8] recognized that soil quality can be assessed from two different viewpoints or methodological approaches, namely (i) as an inherent characteristic or attribute of the soil, or (ii) as the condition of the soil to function fully and adequately in a specific use.…”

Since the 1980s, there has been a notable increase in environmental sensitivity, which has decisively contributed to an improved perception of the role of soil in ecosystems. European (and especially Mediterranean) soils have a long tradition of use, which places them among the three Earth soils that have been affected the most by anthropic pressure. The definition of soil quality identifies and recognizes the soil’s main functions regarding productivity, environmental quality, and human health. Interpreting the criteria for assessing soil quality requires continuous information on its state. Therefore, certain measurable characteristics and properties of the soil are useful, as they can be affected by processes that impact its quality, and analyzing its variation can reflect or show that impact. The parameters used to measure a soil’s state are called indicators. Indicators are useful because they provide summarized and simplified information on the state of a process, but with a meaning that goes beyond an association with an individual parameter. There is an urgent need for consensus among soil scientists and institutions on the concept of soil quality and the applicable environmental quality indicators, as well as establishing interpretative guides for the selected indicators. Soil quality can be analyzed and assessed using several scales with different analysis objectives, information requirements, soil data, implications, and consequences for appropriate soil management. Spanish soil scientists developed a methodological proposal to assess the environmental quality of soil, its environmental impact, and plan and organize land use in the scope of a Mediterranean region. This manuscript is a contribution to the knowledge of the state-of-the-art research in the field of assessing the environmental quality of soils, providing the vision of numerous authors and a methodological proposal for an assessment on a regional scale that may be of interest in other regions or fields of study.

“…Concentrations and forms of metals in sewage sludge are determined by the type of activity that supplies wastewater to treatment plants (Alcantara et al., 2009; Bittencourt et al., 2016). Among metals that can contaminate sewage sludge, lead (Pb) is a common environmental pollutant (Barbosa et al., 2020; Jordán‐Vidal et al., 2021) that can cause several diseases, decreases lifespan and is particularly toxic to children due to potentially permanent learning and behavior disorders (Boskabady et al., 2018).…”

“…The application of sewage sludge containing 176 mg kg −1 of Pb to a mine spoil also resulted in reduced bioavailability of metals (van Herwijnen et al., 2007). Metals tend to bond to the organic matter of sewage sludge (Jordán‐Vidal et al., 2021; van Herwijnen et al., 2007), and the formation of stable phase minerals has been reported as a reduction mechanism of Pb availability in soils and mine spoils amended with this residue (Andrés & Francisco, 2008). However, limed sewage sludge may surpass soil mineralogy as soluble forms of Pb preferentially precipitate with carbonates when soil pH reaches values close to 8.0 (Brown et al., 2003).…”

Little attention has been paid to the effects of soil mineralogy on remediation efficiency of sewage sludge. To fill this gap, we applied limed sewage sludge to Pb‐contaminated soil samples of an Oxisol rich in hematite (309 g kg−1) and gibbsite (322 g kg−1) and to an Inceptisol rich in kaolinite (683 g kg−1). Soil samples were collected from B horizon, being both of them acid, clayey, and poor in organic matter. Soil samples were incubated for 40 days and evaluated for Pb after fractioning. Limed sewage sludge neutralized the soluble and exchangeable‐Pb forms in the kaolinitic and oxidic soils primarily as a result of pH increase. It was measured increased concentrations of unavailable forms of Pb such as precipitated‐Pb, Fe and Mn oxide‐Pb, gibbsite and kaolinite‐Pb, and residual‐Pb in the kaolinitic Inceptisol. Likewise, it measured increased concentrations of precipitated‐Pb, organic matter‐Pb, Fe and Mn oxide‐Pb, and residual‐Pb in the Oxisol. Results have demonstrated that limed sewage sludge decreases concentrations of Pb fractions more susceptible to leaching or more bioavailable, while increasing Pb fractions that pose lower risks to the environment. Such results indicate that limed sewage sludge can be used for the remediation of Pb‐contaminated soils regardless of soil mineralogy.
