The capacity of graphene oxide nanoparticles (nGOx) to reduce or increase As and metals availability in polluted soils was compared with that zero valent iron (nZVI). nanomaterials used this study were characterized by X-ray techniques, CHNS-O analysis, dynamic light scattering, microscopy procedures such as atomic force microscopy. To assess the these materials immobilize pollutants, field samples two treated nZVI nGOx at a range doses (0.2%, 1% 5%). Availability tests then performed....
Soil organic carbon (SOC) is essential for maintaining ecosystem health, and its depletion widely recognized as a key indicator of soil degradation. Activities such mining wildfire disturbances significantly intensify degradation, leading to quantitative qualitative declines in SOC. Accurate SOC monitoring critical, yet traditional methods are often costly time-intensive. Advances technologies like Unmanned Aerial Vehicles (UAVs) satellite remote sensing (SRS) now offer efficient scalable...
Zero valent iron nanoparticles (nZVI) attract interest given their effectiveness in soil remediation. However, little attention has been to impacts on plants. Likewise, although fertilizers are commonly used enhance phytoremediation, effects As mobilization, resulting potential toxic effects, require further study. In this context, we examined the impact of and Hg accumulation antioxidative system Medicago sativa grown a amended with organic fertilizer and/or nZVI. The experiment consisted...
The recurrence and severity of wildfire is on the rise due to factors like global warming human activities. Mediterranean regions are prone significant events, which cause extensive damage ecosystems soil properties. This study focuses municipality Allande in south-western Asturias (Spain), a region highly affected by recurrent wildfires. In this regard, we sought examine how such fires influences organic carbon fractionation other parameters, as nitrogen fractionation, pH, cation exchange...
The combination of a low-density geochemical survey, multispectral data obtained with Unmanned Aerial Vehicle-Remote Sensing (UAV-RS), and machine learning technique was tested in the search for statistically robust prediction contaminant distribution soil vegetation, zones highly variable pollutant load. To this end, novel methodology devised by means limited study topsoil vegetation combined UAV-RS. verified an area affected Hg As contamination that typifies abandoned mining-metallurgy...
Here we addressed the capacity of distinct amendments to reduce arsenic (As), copper (Cu), selenium (Se) and zinc (Zn) associated risks improve biogeochemical functions post-mining soil. To this, examined nanoparticles (NPs) and/or biochar effects, combined with phytostabilization using Lolium perenne L. Soil samples were taken in a former metal mine surroundings. Ryegrass seeds sown pots containing different combinations NPs (zero-valent iron (nZVI) or hydroxyapatite (nH)) (0 2 %), (0, 3 5...
Abstract Wildfires have a significant impact on Soil Organic Carbon (SOC) content and fractionation. Here we used Diffuse Reflectance Spectroscopy (DRS) Machine Learning (ML) algorithms, particularly decision tree-based ones, to assess post-wildfire changes in labile, removable, recalcitrant SOC fractions across six distinct areas with varying wildfire recurrence levels. Once spectral data had been acquired by DRS, the transformation of raw through first second derivatives enhanced...
A bioslurry reactor was designed and used to treat loamy clay soil polluted with polycyclic aromatic hydrocarbons (PAHs). To this end, biostimulation alone, or combined bioaugmentation two bacterial strains (Rhodocccus erythropolis Pseudomonas stuzeri) previously isolated from the site, applied. The PAH concentrations decreased notably after 15 days in all of treatments. two- three-ring compounds fell by >80%, and, remarkably, four- six-ring PAHs also showed a marked decrease (>70%)....
Abstract Background and aim The use of amendments to immobilize metals in polluted soils is a widely accepted remediation approach, the framework circular economy, produced from mining and/or biomass waste have gained relevance. However, application such can also mobilize metalloids. Here we propose combination nanoscale zero-valent iron nanoparticles (nZVI) with dunite (mining waste) compost for restoration soil affected by high concentrations As metals. Methods To this end, treated pots...
Phytoremediation is a cost-effective nature-based solution for brownfield reclamation. The choice of phytoextraction or phytostabilization strategies highly relevant when planning full-scale treatments. A suitable approach to identify such species involves the evaluation plants that grow spontaneously on contaminated sites. Here, we sought determine phytoremediation potential three spontaneous plant species, namely trees Acer pseudoplatanus L (A. pseudoplatanus) and Betula celtiberica Rothm....
Abstract Mining is a cornerstone of the productive system, particularly in sectors, such as renewable energy and electronic equipment production, where its significance anticipated to grow coming years. Aligned with principles Nature-Based Solutions Zero Waste policies, recycling mining waste soil amendments could concurrently restore degraded areas reduce disposal waste. In this context, we aimed remediate post-mining primarily impacted by heavy metal pollution using an alkaline generated...
Control of Potentially Toxic Elements (PTEs) in soil-polluted areas is needed to address the potential risk that pollution poses public health and environment. This study describes an innovative holistic methodology assess distribution PTEs. It based on application multi-variate statistical geostatistical algorithms, soil indices geochemical & geomorphological/climate variables (element concentration, watercourses, winds, slope, orientation visibility). The proposed exemplified through a...
