Abstract:
... Natural siderite (FeCO₃), simulated synthetic siderite and nZVI/FeCO₃ composite were used as green and easily available iron-based catalysts in peroxydisulfate activation for remediating 2-chlorophenol as the target contaminant and this technique can effectively degrade organic pollutants in the soil. The key reaction parameters such as catalysts dosage, oxidant concentration and pH, were investig ...
... Agricultural soils are in peril. Multiple lines of observational and empirical evidence suggest that we are losing the world’s fertile soils at an alarming rate, worsening the on-going global food crisis. It is increasingly clear that the risk of soil crises driven by erratic precipitation, warming air, and farming mismanagement is coming sooner rather than later. At this critical time, society ca ...

Abstract:
... The results of the study of the properties of urban soils of the city of Sibay located in the mining region of the Republic of Bashkortostan are presented. A specific feature of the studied territory is a significant distribution of soils with strong and very strong physical degradation, rocks buried under dumps, and replantozems in reclaimed areas. At the same time, the traditional way of life of ...

Abstract:
... The research of polylactic acid (PLA) packaging materials with high degradation rate is important toward high rate biodegradable packaging materials. The samples (PLA-mango seed residue-clays) were evaluated by degradation analysis (in water and in soil) followed by FTIR, NMR, SEM/EDS and Texturometer analysis. The samples degradation was more effective in water than in soil, probably due to a cou ...
soildegradation, etc ; cathodes; durability; electrochemistry; heavy metals; pollution; soil nutrients; soil remediation; Show all 8 Subjects
Abstract:
... The demands for genuine remediation of heavy metal contaminated soil have triggered extensive studies in the soil washing method. However, numerous soil washing methods show poor sustainability for target soil, due to the tremendous cost, hidden secondary pollution and severe soil deterioration. Here, an asymmetrical alternating current electrochemically-mediated remediation platform (ACRP) is dev ...
soildegradation, etc ; algorithms; analytical chemistry; cost effectiveness; mass spectrometry; metabolites; metabolomics; pollution; Show all 8 Subjects
Abstract:
... Stable isotope-assisted metabolomics (SIAM) enables global tracking of isotopic labels in nontargeted metabolomics in living organisms. However, its application in tracking transformation products (TPs, as metabolites of contaminants) of environmental contaminants is still a challenge due to limits in methodology, unmatured algorithms, and the high cost of ¹³C-labeled contaminants. Therefore, we d ...

Abstract:
... The use of cyanobacteria as soil inoculants is a very promising biotechnological approach that is receiving increasing scientific attention for its potential for soil degradation control. Inoculation of selected cyanobacterial strains has shown the ability to significantly improve the physicochemical properties of degrading soils in different environmental settings and on soils with different text ...

Abstract:
... Understanding the soil and water conservation (SWC) impact of steep‐slope agricultural practices (e.g. terraces) has arguably never been more relevant than today, in the face of widespread intensifying rainfall conditions. In Italy, a diverse mosaic of terraced and non‐terraced cultivation systems have historically developed from local traditions and more recently from the introduction of machiner ...

Abstract:
... Applying a Regional Integrated Vulnerability Assessment (RIVAS), this study aims to identify the local farming system characteristics of 54 smallholder agroforestry farms in Kafa Zone (Ethiopia), their climate change vulnerability, and how they are affected by current land-use changes. The study combines semi-structured interviews with a biophysical characterization of farm systems. The results sh ...
soildegradation, etc ; biodegradability; cellulose; nanocomposites; nanocrystals; polyvinyl alcohol; solubility; strength (mechanics); water uptake; water vapor; Show all 10 Subjects
Abstract:
... Polyvinyl alcohol (PVA) is used in many applications because of its excellent physicochemical properties, non-toxicity, and biodegradability. However, its relatively low water resistance, poor water vapor/ultraviolet (UV) barrier properties, and poor mechanical properties compared with conventional polymers limit its applications in food packaging. In this study, cellulose nanocrystals (CNCs) and ...

Abstract:
... The reconstitution pedotechnique is a process based on the treatment of organic and nonorganic matrices for restoring ecosystem and agroforestry functions of soils and for producing specific Technosols. The technology applies a conceptual model based on the production of new soil aggregates with targeted environmental and soil characteristics generated via a chemical–mechanical process that entail ...

Abstract:
... Hydrolysis, photolysis, and soil degradation are important degradation pathways of pesticides and might generate toxic chemicals and pose threats to the environment. Sulfoxaflor is a widely used neonicotinoid pesticide, but few studies have been conducted to research its environmental behaviors and residues. Herein, the hydrolysis and photolysis of sulfoxaflor in water and degradation in four typi ...

Abstract:
... Soil degradation, affecting around 38% of the world's cropland, threatens the global food supply. Due to the soil's complexity, the measure of soil degradation that involves the loss of soil fertility due to crop system management processes represents an unsolved problem. Exergy is a property with the potential to be used in soil fertility and/or degradation analysis. A methodology to determine th ...

Abstract:
... Land use change is one of the major drivers of soil degradation, affecting the ability of soils to supply multiple ecosystem services (ES). Despite the growing importance of soil-related ES, there is a lack of comprehensive methodologies to systematize how land use change affects the ability of soil to supply them. Here, by using primary information on soil properties, we develop a series of indic ...

Abstract:
... The locution “hydrological connectivity inside the soil” is generally used to disclose how the spatial patterns inside the soil affect the physical–chemical processes at a molecular level to influence water transfer into the soil, the surface runoff and related sediment transport. Fast Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) relaxometry has been used to measure both structural and fun ...

Abstract:
... Dust emission is an important corollary of the soil degradation process in arid and semi-arid areas worldwide. Soil organic carbon (SOC) is the main terrestrial pool in the carbon cycle, and dust emission redistributes SOC within terrestrial ecosystems and to the atmosphere and oceans. This redistribution plays an important role in the global carbon cycle. Herein, we present a systematic review of ...
... The recently recognized adverse environmental and toxic effects of neonicotinoid insecticides (NNIs) on non-target organisms are alarming. A comprehensive design, screening, and regulatory system was developed to generate NNI derivatives and mutant receptors with selective-ecotoxicological effects to overcome such adverse effects. For ligand design, taking ACE-09 derivative as an example, the toxi ...
