Texto completo da fonteResumo:
The concurrent presence of arsenic (As) and cadmium (Cd) contamination in soil is widespread and severe, highlighting the need for remediation. However, remediating As and Cd co-contaminated soils is more complex than remediating soils contaminated with a single heavy metal due to the opposite properties of As and Cd in soil. Thus, the different forms of As and Cd in co-contaminated soils and their transformation rules have been systematically reviewed in this paper. Simultaneously, hyperaccumulators and immobilization amendments used in the remediation of As–Cd co-contaminated soil were reviewed. Moreover, the mechanisms of phytoremediation and chemical immobilization techniques in the treatment of As and Cd co-contaminated soil and the remediation effects were expounded in detail. To promote the development of ecological civilization, this paper proposes further remediation strategies and guidance for the remediation of As–Cd co-contaminated soil.

Texto completo da fonteResumo:
Nanotechnology has been widely used in many fields including in soil and groundwater remediation. Nanoremediation has emerged as an effective, rapid, and efficient technology for soil and groundwater contaminated with petroleum pollutants and heavy metals. This review provides an overview of the application of nanomaterials for environmental cleanup, such as soil and groundwater remediation. Four types of nanomaterials, namely nanoscale zero-valent iron (nZVI), carbon nanotubes (CNTs), and metallic and magnetic nanoparticles (MNPs), are presented and discussed. In addition, the potential environmental risks of the nanomaterial application in soil remediation are highlighted. Moreover, this review provides insight into the combination of nanoremediation with other remediation technologies. The study demonstrates that nZVI had been widely studied for high-efficiency environmental remediation due to its high reactivity and excellent contaminant immobilization capability. CNTs have received more attention for remediation of organic and inorganic contaminants because of their unique adsorption characteristics. Environmental remediations using metal and MNPs are also favorable due to their facile magnetic separation and unique metal-ion adsorption. The modified nZVI showed less toxicity towards soil bacteria than bare nZVI; thus, modifying or coating nZVI could reduce its ecotoxicity. The combination of nanoremediation with other remediation technology is shown to be a valuable soil remediation technique as the synergetic effects may increase the sustainability of the applied process towards green technology for soil remediation.

"Asynchronous Synergetic Remediation Strategy for Cd-Contaminated Soil via Passivation and Phytoremediation Technology." Agronomy 14, no. 9 (August 26, 2024): 1913. http://dx.doi.org/10.3390/agronomy14091913.
Texto completo da fonteResumo:
Cadmium (Cd) contamination in soil has emerged as a significant challenge for agricultural production. Phytoremediation and passivation are key techniques for remediating Cd-contaminated soil. However, few studies have focused on the synergistic effects of these two techniques. In this work, the effectiveness of synergetic remediation strategies, both synchronous and asynchronous, utilizing passivation and phytoremediation techniques, was explored. The results of pot experiments and field experiments indicated that optimal remediation effects were obtained by asynchronous synergetic remediation, removing over 80% of bioavailable Cd within 14 days. Mechanistic studies conducted using XPS analysis, soil property analysis, and microbial diversity analysis confirmed that the chelation effect of SDD and soil pH value are the primary factors contributing to the effectiveness of both remediation strategies. In contrast, the variations in microbial populations are identified as the crucial factors influencing the varying outcomes of the two sequential remediation approaches. This research demonstrates that asynchronous synergistic remediation is a promising strategy for mitigating Cd contamination in soil.

Texto completo da fonteResumo:
The article undertakes a comprehensive examination of the phenomenon of book remediation through the lens of the theoretical framework presented by American researchers J. Bolter and D. Grusin. Drawing on statistical data illustrating the role of books in the lives of Ukrainians, the author validates the assertion that books no longer occupy a central position in the leisure pursuits of contemporary individuals. However, it is intriguing to note that the majority of today's popular media actively engage in the process of remodeling books. Defined inherently as multimedia, contemporary audiovisual art is characterized by remediation, with video games chosen as the most technologically advanced exemplar within this genre. Notably, the analysis reveals a significant gap in previous research, specifically, the lack of attention to the nuanced connection between the characteristics of remediating books in the context of video games. A key revelation is that the frequency of remediating books through video games is contingent on the genre, with games prioritizing gameplay mechanics over plot exhibiting a lower propensity for book remediation. The form of remediation in such video games is conditional, primarily associated with the intricacies of the game interface. Conversely, in narrative-centric video games, remediation tends to involve a more direct interaction with the book. Expanding beyond the initial scope of inquiry, the study identifies and scrutinizes additional factors influencing remediation. The setting of the game and the player's perspective emerge as crucial variables, with book remediation more prevalent in video games set in fantasy archaic or modern environments compared to those set in fantastical realms. An equally significant factor, rivaling genre influence, is the player's perspective, notably observed in first-person games which exhibit a propensity to eschew hypermedia in their interaction with the game world — a tendency most pronounced in video games leveraging virtual reality technology.

The Electro kinetic Remediation Technology (EKR) is recognized as the most potential remediation technology for soils with low permeability, like clay soil characteristics. Electrokinetic treatment could increase the bioavailability of contaminants in bioremediation petroleum-contaminated soil. The study, “Bioavailability enhancement of petroleum contaminated soil by electrokinetic remediation,” is experimental research in a laboratory to improve the bioavailability of petroleum hydrocarbons on clay during bioremediation with initial treatment using electrokinetic remediation techniques, finding optimum electrokinetic operating conditions of remediations, and analyzing the mechanism of remediation process in contaminated soil. Bioavailability enhancement was studied for 35 days. Polluted soil was treated with an electrokinetic box test (17cm×12cm×10cm), and DC power was used for 48 hours. Total Petroleum Hydrocarbon (TPH) concentration was determined by gravimetric methods. The results showed that the characteristics of the soil samples were dominated by 49.31% clay. The initial concentration of TPH in polluted soil is 3.7%. The electrokinetic applications during 48 hours and followed by bioremediation for 35 days those processes removed TPH up to 80.74 % (from 33780.66 mg HC (kg dry w)-1 to 6506.155176 mg HC (kg dry w)-1. There is an increase in bioavailability indicated by the rise in bacterial populations and an increase in biodegradation after electrokinetic remediation. With this approach, bioavailability has been increased by 70.18%. Bio-electrokinetic remediation is the recommended method for polluted clay soils with low bioavailability.

Texto completo da fonteResumo:
Objective: An important goal of chiropractic educational institutions is to ensure that all graduates reach an acceptable level of clinical competency and thus institutions are equipped to offer traceable remediation when skills fall below certain benchmarks. Methods: Working with key individuals in the faculty, administration, and assessment department, a process of remediation was created and materials were produced that could be used by faculty and assessment staff to focus on a student's lack of knowledge, technique, or documentation in specific clinical skill areas. The primary goal was to create an individualized remediation plan that suits the specific needs of the student. Results: Utilization of the remediation center continues to increase. Referrals to the center for fiscal years 2015, 2016, and 2017 were 60, 125, and 126 students, respectively. Retesting rates after remediation continue to be high, with 98.3%, 95.2%, and 95.8% for fiscal years 2015, 2016, and 2017, respectively. Conclusion: We developed and implemented a chiropractic remediation program to satisfy the need for objectively identifying and remediating clinical skill deficiencies. This remediation program experienced an increase in use in its initial 3 years of operation, indicating more inclusion of the program across the departments, clinics, and assessment. The outcome of remediation is still not clear because there are no consistent assessment measures in place to determine pre- and postremediation student performance.

ABSTRACT This study investigates whether assured disclosures of management's remediation of material weaknesses in internal controls affect positively unsophisticated investor perceptions of disclosure credibility and the likelihood of their investing in a firm. The results indicate that investors perceive assured material weakness remediation disclosures, whether the audit source is external or internal to the firm, to be more credible than unassured disclosures. Specifically, external assurance is seen to be more credible than the assurance provided by internal auditors but that is seen as more credible than no assurance. However, investment likelihood remains the same regardless of assurance source. Furthermore, the results indicate that investor disclosure credibility perceptions and investing likelihood are lower for internally assured pervasive material weakness remediation disclosures than internally assured account-specific remediations and all externally assured remediation disclosures. Finally, mediation results suggest that both internal and external auditor assurance increases investing likelihood indirectly through increased disclosure credibility.

Sediments are important in influencing changes and movements of the heavy metals in the aquatic environment. Heavy metals contamination of the sediments has negative ecological impacts on the environment. Therefore, economical, effective, and environmentally friendly remediation processes are needed. Purposes of the remediation are to reduce toxicity, bioavailability, and mobility of the metals from the polluted sediments. The remediations are developed using physical-chemical, biological and combination of both techniques. Physical-chemical techniques are carried out to decrease the stability of contaminated substances. Biological techniques or known as bioremediation are conducted through biological processes of plants, animals, and microorganisms. While the combination of both respective techniques, can produce maximum benefits and increase remediation efficiency.

Texto completo da fonteResumo:
Electrokinetic remediation has, in recent years, shown great potential in remediating polluted environments. The technology can efficiently remove heavy metals, chlorophenols, polychlorinated biphenyls, phenols, trichloroethane, benzene, toluene, ethylbenzene, and xylene (BTEX) compounds and entire petroleum hydrocarbons. Electrokinetic remediation makes use of electrolysis, electroosmosis, electrophoresis, diffusion, and electromigration as the five fundamental processes in achieving decontamination of polluted environments. These five processes depend on pH swings, voltage, electrodes, and electrolytes used in the electrochemical system. To apply this technology at the field scale, it is necessary to pursue the design of effective processes with low environmental impact to meet global sustainability standards. It is, therefore, imperative to understand the roles of the fundamental processes and their interactions in achieving effective and sustainable electrokinetic remediation in order to identify cleaner alternative solutions. This paper presents an overview of different processes involved in electrokinetic remediation with a focus on the effect of pH, electrodes, surfactants, and electrolytes that are applied in the remediation of contaminated soil and how these can be combined with cleaner technologies or alternative additives to achieve sustainable electrokinetic remediation. The electrokinetic phenomenon is described, followed by an evaluation of the impact of pH, surfactants, voltage, electrodes, and electrolytes in achieving effective and sustainable remediation.

Texto completo da fonteResumo:
Global governance of soil resources as well as revitalizations and remediation of degraded areas seem to be necessary actions for sustainable development. A great deal of effort has gone into developing remediation technologies to remove or reduce the impact of these contaminants in the environment. However, contaminated soil remediations in stringent conditions deteriorate soil properties and functions and create the need for efficient soil revitalization measures. Soil washing (SW) and thermal desorption (TD) are commonly used to remediate contaminated soil and can significantly reduce the contaminant, sometimes to safe levels where reuse can be considered; however, the effects of treatment on soil quality must be understood in order to support redevelopment after remediation. In this review, we discussed the effects of SW and TD on soil properties, including subsequent soil quality and health. Furthermore, the importance of these techniques for remediation and reclamation strategies was discussed. Some restoration strategies were also proposed for the recovery of soil quality. In addition, remediated and revitalized soil can be reused for various purposes, which can be accepted as an implementation of sustainable remediation. This review concludes with an outlook of future research efforts that will further shift SW and TD toward sustainable remediation.

Texto completo da fonteResumo:
The application of persulfate (PS) for the remediation of petroleum hydrocarbon contamination is among the most widely employed in situ chemical oxidation (ISCO) techniques, and it has received widespread attention due to its limited impact on soil integrity. This study employed a FeSO4-activated PS oxidation method to investigate the feasibility of remediating soil contaminated with total petroleum hydrocarbons (TPHs). The factors tested included the TPH concentration, different PS:FeSO4 ratios, the reaction time for remediation, soil physical and chemical property changes before and after remediation, and the effect of soil before and after remediation on soybean growth. The TPH degradation rate in soil was highest for high-, medium-, and low-TPHs soils—81.5%, 81.4%, and 72.9%, respectively, with minimal disruption to the soil’s physicochemical properties—when PS:FeSO4 = 1:1. The remediation verification results indicated that the condition of the soybeans was optimal when PS:FeSO4 = 1:1. Under this condition, the net photosynthetic rate, stomatal conductance, intercellular CO2 concentration, and transpiration rate all remained high. Therefore, the best remediation effect was achieved with PS:FeSO4 = 1:1, which also minimized the damage to the soil and the effects on crop growth.

Texto completo da fonteResumo:
Heavy metal pollution in soil is a significant challenge around the world, particularly cadmium (Cd) contamination. In situ phytoextraction and remediation technology, particularly focusing on Cd hyperaccumulator plants, has proven to be an effective method for cleaning Cd-contaminated agricultural lands. However, this strategy is often hindered by a long remediation cycle and low efficiency. To address these limitations, assisted phytoextraction has been proposed as a remediation strategy based on the modification of certain traits of plants or the use of different materials to enhance plant growth and increase metal absorption or bioavailability, ultimately aiming to improve the remediation efficiency of Cd hyperaccumulators. To thoroughly understand the progress of Cd hyperaccumulators in remediating Cd-polluted soils, this review article discusses the germplasm resources and assisted phytoextraction strategies for these plants, including microbial, agronomic measure, chelate, nanotechnology, and CO2-assisted phytoextraction, as well as integrated approaches. This review paper critically evaluates and analyzes the numerous approaches and the remediation potential of Cd hyperaccumulators and highlights current challenges and future research directions in this field. The goal is to provide a theoretical framework for the further development and application of Cd pollution remediation technologies in agricultural soils.

Texto completo da fonteResumo:
The choice between remediation alternatives for contaminated sites is complicated by different elements, e.g., the occurrence of multiple contaminants, the extent of the contamination, or the urban location, complicate the choice between remediation alternatives. This paper addresses this challenging choice by analyzing a case study of an extensive soil and groundwater contamination by a dry-cleaning company. For remediating this site, two alternatives were proposed. The first remediation alternative combines several techniques with in-situ chemical oxidization being the most important one. Due to the potential negative impact of this alternative on local residents a second remediation alternative was drawn up, in which the focus lies on the use of stimulated biological degradation. A Life Cycle Assessment (LCA) was performed on both alternatives and showed that the second alternative had a lower environmental impact. The inclusion of monetized LCA results in the calculation of a social Cost-Benefit Analysis (CBA) provided a more extensive view of the secondary environmental costs and benefits of the remediation alternatives. The results of the social CBA allow to conclude that both alternatives are not socially desirable, the chemical alternative however is socially less disadvantageous than the more natural remediation alternative.

The use of pesticides presents a looming danger to the living elements of our ecological system, crops, and the well-being of our species. As an outcome, various organic contaminants pollute the soil. Different physical, chemical, and biological remediation techniques have been employed for the decontamination of pesticide-polluted soils. Remediation technology should always be affordable, on-site or in-situ, and capable of restoring the soil's natural functionality. The presence of multiple pesticides can pose challenges in effectively remediating them from the soil. The present work examines the scientific literature on the benefits and drawbacks of various existing and emerging soil remediation techniques. Customized technology choices and designs for specific site conditions enhance the effective cleanup of polluted areas. The present study, which evaluates and contrasts various technological approaches, shall serve as an invaluable tool for determining the optimal soil remediation method for a given contamination dilemma.

Texto completo da fonteResumo:
Lead (Pb) contamination in loess poses a significant environmental challenge that impedes sustainable development. Microbially induced carbonate precipitation (MICP) is an innovative biomimetic mineralization technology that shows considerable promise in remediating soil contaminated with heavy metals. However, the toxicity of lead ions to Bacillus pasteurii reduces the efficiency of mineralization, subsequently diminishing the effectiveness of remediation. Although biochar can immobilize heavy metal ions, its adsorption instability presents a potential risk. In this study, we first compared the pH, electrical conductivity (EC), unconfined compressive strength (UCS), permeability coefficient, and toxicity leaching performance of lead-contaminated loess specimens remediated using biochar (BC), red mud (RM), red-mud-modified biochar (MBC), and MICP technology. Additionally, we evaluated the mechanism of MICP combined with varying amounts of MBC in remediating lead-contaminated loess combing Zeta potential, X-ray diffraction (XRD) analyses, and scanning electron microscopy (SEM) tests. The results showed that MICP technology outperforms traditional methods such as RM, BC, and MBC in the remediation of lead-contaminated loess. When MICP is combined with MBC, an increase in MBC content results in a higher pH (8.71) and a lower EC (232 us/cm). Toxic leaching tests reveal that increasing MBC content reduces the lead leaching concentration in loess, with optimal remediation being achieved at 5% MBC. Microscopic analysis indicates that the remediation mechanisms of MICP combined with MBC involve complexation, electrostatic adsorption, ion exchange, and precipitation reactions. The synergistic application of MICP and MBC effectively adsorbs and immobilizes lead ions in loess, enhancing its properties and demonstrating potential for pollution remediation and engineering applications.

AbstractStruggling trainees exist in all residency programs across all fields. Remediation, the act of improving deficiencies in struggling trainees, is necessary to promote the graduation of competent physicians. Deficiencies may be primarily cognitive or behavioral, and occasionally physical limitations do arise during residency. Remediation is challenging for all parties involved, and there is a paucity of literature to help guide the most effective process. In this review, we outline key principles of effective remediation of a struggling trainee in the modern era of medical education. A systematic approach that begins early, is consistent, and remains sensitive to a trainee's need for self-reflection in a nonjudgmental culture is essential for successfully remediating a trainee.

The purpose of this paper is to provide examples of strategies and procedures for remediation of buildings affected by toxic moulds. Four case studies are included in the paper. Moisture and inadequate ventilation are the keys to proliferation of toxic moulds and dispersion of spores in air. Prevention should always be the main objectives for any environmental management plan or service maintenance of a building. The management and remediation plan should include an adequate control of moisture, damp and ventilation in the building. The most effective strategy for remediating mould problems is by source control, preventing or limiting the generation of moulds, and the other is to remove the sources. There should be a detailed study to identify the sources of mould problems. The remediation could involve mothballing of a building to rectify defects including leaks and removal of damp materials; venting of underfloor or wall cavities and to improve the general airflow in the building. Remediation may involve vacuuming to remove spores in air and mould from surfaces. Other techniques include heat treatment, steam cleaning, biocides treatment, fumigation and UV treatment.

Extensive mining of rare earth deposits has caused severe soil erosion, resulting in the degradation of plant–soil systems and the reduction in microbial diversity. Combined ecological remediation technology is the key method of vegetation reconstruction and ecological restoration in abandoned tailings. In this study, the effects of different cover crops–biochar–organic fertilizer and biochar–organic fertilizer treatments on soil fungal communities in rare earth tailings soil were analysed using high-throughput sequencing technology. Linear discriminant analysis effect size (LEfSe) was used to analyse saprophytic, mycorrhizal, and potential pathogenic fungi in soils after different combined remediations. Moreover, the effects of soil environmental factors on fungal community species’ composition were analysed by redundancy analysis (RDA) and variance partitioning analysis (VPA) after different combined remediations. LEfSe indicated a risk of citrus pathogenicity by Diaporthaceae indicator fungi after biochar–organic fertilizer combined treatment. RDA and VPA revealed that pH was the main environmental factor affecting the fungal community in the different combined remediation treatments. Additionally, the Paspalum wettsteinii cover crops–biochar–organic fertilizer and biochar–livestock manure treatments were more conducive to arbuscular mycorrhizal fungi recruitment. We also clarified the fungal community composition structure, soil environmental factors, and fungal community relationships in rare earth tailings soil after different combined remediation treatments.

Texto completo da fonteResumo:
Anthropogenic activities and increasing human population has led to one of the major global problems of heavy metal contamination in ecosystems and to the generation of a huge amount of waste material biomass. Hexavalent chromium [Cr(VI)] is the major contaminant introduced by various industrial effluents and activities into the ecosystem. Cr(VI) is a known mutagen and carcinogen with numerous detrimental effects on the health of humans, plants, and animals, jeopardizing the balance of ecosystems. Therefore, the remediation of such a hazardous toxic metal pollutant from the environment is necessary. Various physical and chemical methods are available for the sequestration of toxic metals. However, adsorption is recognized as a more efficient technology for Cr(VI) remediation. Adsorption by utilizing waste material biomass as adsorbents is a sustainable approach in remediating hazardous pollutants, thus serving the dual purpose of remediating Cr(VI) and exploiting waste material biomass in an eco- friendly manner. Agricultural biomass, industrial residues, forest residues, and food waste are the primary waste material biomass that could be employed, with different strategies, for the efficient sequestration of toxic Cr(VI). This review focuses on the use of diverse waste biomass, such as industrial and agricultural by-products, for the effective remediation of Cr(VI) from aqueous solutions. The review also focuses on the operational conditions that improve Cr(VI) remediation, describes the efficacy of various biomass materials and modifications, and assesses the general sustainability of these approaches to reducing Cr(VI) pollution.

The rapid industrialization and economic growth have exacerbated the contamination of soils with both heavy metals and organic pollutants. These persistent contaminants pose substantial threats to ecosystem integrity and human health due to their long-term environmental persistence and potential for bioaccumulation. Biochar, with its high specific surface area, well-developed pore structure, and abundant surface functional groups, has emerged as a promising material for remediating soils contaminated by heavy metals and organic pollutants. While some research has explored the role of biochar in soil remediation, several aspects remain under investigation. Fully harnessing the potential of biochar for soil contamination remediation is of critical importance. This review provides an overview of the preparation methods and physicochemical properties of biochar, discusses its application in soils contaminated by organic compounds and/or heavy metals, and examines the mechanisms underlying its interaction with pollutants. Additionally, it summarizes the toxicity assessments of biochar during soil remediation and outlines future research directions, offering scientific insights and references for the practical deployment of biochar in soil pollution remediation.

Texto completo da fonteResumo:
Farmers are one of the major uncertainty factors in remediation of contamination farmland. Based on the face-to-face questionnaire survey data of 553 farmers in 4 heavy metal-contaminated agricultural soil remediation projects in China, this study used methods, such as structural equation modeling and random forest to explore farmers’ willingness to remediate, technology preference, and their key influencing factors for the first time. The results showed that farmers were willing to remediate contaminated soil and preferred phytoremediation, with 82.8% choosing phytoremediation, 12.5% choosing passivation, and 4.7% believing that the soil did not need to be remediated. In terms of willingness to remediate, the perceived benefits from participation in current remediation projects directly contributed to future willingness, with participation status (total impact coefficient 0.86) and perceived benefits (impact coefficient 0.49) being the main factors positively influencing farmers’ willingness. With regard to technology preference, technical characteristics (soil quality, 17.1%; secondary contamination, 16.8%; and remediation period, 11.5%) were the main influencing factors. The sustainability of passivation effect and the possible secondary contamination restrict the promotion of passivation, whereas the cessation of agricultural production during the long remediation period restricts the promotion of phytoremediation. It is recommended to increase farmers’ willingness to remediate by improving their perceived benefits and continuously overcoming the technical barriers by: (i) developing efficient and green passivators; and (ii) improving the efficiency of phytoremediation as well as intercropping or rotating cash crops while remediating. The results have important reference value for soil remediation in agricultural countries with small arable land per capita.

This study evaluates the effectiveness of biochar, derived from maize cobs and poultry litter, and compost in remediating soils contaminated with lead (Pb) and cadmium (Cd) using <em>Amaranthus hybridus</em> as a test crop. Pot experiment was conducted using soils from an iron-pot industry dumpsite and a contaminated fadama (valley bottom) soil, treated with varying application rates of biochar (maize cobs and poultry litter) and compost (0, 5, 10, and 15 g/kg). Growth parameters, Biomass Yield, Remediation percentage, lead and cadmium in the soils and plant were determined 6 weeks after planting, following standard procedures. Data were analyzed using descriptive statistics, polynomial regression and ANOVA at α<sub>0.05, </sub>It was observed that increasing the application rate of both amendments significantly enhanced the remediation efficiency of Pb and Cd in both soil types, reducing their availability and accumulation in <em>Amaranthus hybridus</em>. The highest remediation was observed at 15 g/kg poultry litter biochar, which achieved 55% and 48% remediation for Pb and Cd, respectively, in the iron-pot industry dumpsite soil, and 56 and 47% remediation in the contaminated fadama soil, for the respective metals. Similarly, this treatment reduced heavy metal uptake by <em>Amaranthus hybridus</em>, enhancing soil pH and reducing metal mobility. The optimal application rate for effective remediation was determined to be between 8.2 and 10.7 g/kg. These findings suggest that biochar, particularly from poultry litter, is effective for mitigating heavy metal contamination in the contaminated soils.

Environmental Pollution is becoming a global challenge in both developing and the developed countries, pollutants discharge from oil and gas industries and or agricultural practices continue effecting the health of human and other animal in an ecosystem in one way or the other. This necessitated the development of a techniques to clean up of the polluted environment. Remediation of pollutants relies mainly on using varioustechniques like physical, chemical and or biological methods for the removal of contaminants from different environmental media be it soil, water, and or air. These techniques have their own limitations as the toxicity of the degrading agents, time consuming and the fate of the environment after remediation matters a lot. Therefore, nanotechnology is gaining interest in remediating pollutions as nanoparticles are relatively cost effective, sensitive and selective and can be used as sensors to monitor toxins, organic contaminants and heavy metals in land, water and or air. The enhanced properties and effectiveness of nanotechnology-based materials makes them suitable for nano remediation. This review provides an overview of the nanomaterials: Organic based nanomaterials (Dendrimers), inorganic (TiO2, nZVI), carbon-based (Carbon nanotubes, (CNTs)), and composite-based materials) used in environmental remediation. These nanomaterials were reported to remediate different contaminants in theenvironment such as heavy metals, pathogens, pesticides, dyes, chlorinated organic compounds, and polycyclic aromatic hydrocarbons.

Texto completo da fonteResumo:
With the rapid development of industry and agriculture, soil heavy metal contamination has become an important environmental issue faced today and has gradually attracted widespread attention. Finding a cheap, widely available, and biodegradable material that can promote crop growth and stabilize heavy metals has become a research focus. Crop straw biochar, due to its high specific surface area, rich surface functional groups, and high cation exchange capacity (CEC), has shown good effects on the remediation of inorganic and organic pollutants in the environment. This article reviews recent research on the use of crop straw biochar for soil heavy metal contamination remediation, providing a detailed analysis from the preparation, characteristics, modification of crop straw biochar, mechanisms for reducing the toxicity of heavy metals in soil, and its application and risks in remediating heavy metal-contaminated soils. It also comprehensively discusses the potential application of crop straw biochar in the remediation of heavy metal-contaminated soils. The results show that crop straw biochar can be used as a new type of immobilizing material for the remediation of heavy metal-contaminated soils, but there are issues with the remediation technology that needs to be optimized and innovated, which poses challenges to the widespread application of crop straw biochar. In the future, efforts should be strengthened to optimize and innovate the application technology of crop straw biochar, conduct research on the remediation effects of cheap modified crop straw biochar and the co-application of crop straw biochar with other immobilizing materials on heavy metal-contaminated soils, and carry out long-term monitoring of the effects of crop straw biochar in soil heavy metal remediation in order to achieve the goal of ensuring food safety and the rational use of solid waste.

Abstract Innovative devices and tools for exposure assessment and remediation play an integral role in preventing exposure to hazardous substances. New solutions for detecting and remediating organic, inorganic, and mixtures of contaminants can improve public health as a means of primary prevention. Using a public health prevention model, detection and remediation technologies contribute to primary prevention as tools to identify areas of high risk (e.g. contamination hotspots), to recognize hazards (bioassay tests), and to prevent exposure through contaminant cleanups. Primary prevention success is ultimately governed by the widespread acceptance of the prevention tool. And, in like fashion, detection and remediation technologies must convey technical and sustainability advantages to be adopted for use. Hence, sustainability – economic, environmental, and societal – drives innovation in detection and remediation technology. The National Institute of Health (NIH) National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) is mandated to advance innovative detection, remediation, and toxicity screening technology development through grants to universities and small businesses. SRP recognizes the importance of fast, accurate, robust, and advanced detection technologies that allow for portable real-time, on-site characterization, monitoring, and assessment of contaminant concentration and/or toxicity. Advances in non-targeted screening, biological-based assays, passive sampling devices (PSDs), sophisticated modeling approaches, and precision-based analytical tools are making it easier to quickly identify hazardous “hotspots” and, therefore, prevent exposures. Innovation in sustainable remediation uses a variety of approaches: in situ remediation; harnessing the natural catalytic properties of biological processes (such as bioremediation and phytotechnologies); and application of novel materials science (such as nanotechnology, advanced membranes, new carbon materials, and materials reuse). Collectively, the investment in new technologies shows promise to reduce the amount and toxicity of hazardous substances in the environment. This manuscript highlights SRP funded innovative devices and tools for exposure assessment and remediation of organic, inorganic, and mixtures of contaminants with a particular focus on sustainable technologies.

Texto completo da fonteResumo:
The present study experimentally investigated two different open-cast post-mining areas with different remediation methods for the vertical distribution of sequestered soil organic carbon (SOC). The study has been performed for two soil layers (0–15 cm, and 15–30 cm) for the four areas with different remediation advancement (up to 20 years) at both studied post-mining soils: the limestone post-mining soil remediated with embankment and lignite post-mining soil remediated with sewage sludge. The study revealed that SOC is more stable within soil depths for lignite post-mining soil remediated with sewage sludge in comparison to the limestone post-mining soil remediated with embankment. The lignite post-mining soil remediated with sewage sludge showed a better hydrophobicity, humidity, aromaticity, and C/N ratio according to the 13C NMR. Therefore, in that soil, an increased microbial community has been observed. The study observed a positive correlation between GRSP content with a fungi community within soil depths. For lignite post-mining soil remediated with sewage sludge, the activity of ureases and dehydrogenases was generally lower compared to the post-mining soil remediation with embankment. The investigation found good parameters of Ce and NCER which for both studied areas were negative which indicate for the privilege of the higher capturing of CO2 over its release from the soil into the atmosphere. The study finds no relevant changes in SOC, POXC, TC, and LOI content within soil depth and remediation age. Due to the lack of a possible well-describing indicator of the vertical distribution of SOC stability in post-mining remediation soil, we proposed two different indicators for differentially managed post-mining soil remediations. The model of calculation of vertical SOC variability index can be universally used for different post-mining soils under remediation, however, both proposed calculated indexes are unique for studied soils. The proposed model of an index may be helpful for remediation management, C sequestration prediction, and lowering the carbon footprint of mining activity.

Texto completo da fonteResumo:
The characteristics of groundwater pollution caused by illegal waste dumping and methods for predicting and remediating it are still poorly understood. Serious 1,4-dioxane groundwater pollution—which has multiple sources—has been occurring at an illegal waste dumping site in the Tohoku region of Japan. So far, anti-pollution countermeasures have been taken including the installation of an impermeable wall and the excavation of soils and waste as well as the monitoring of contamination concentrations. The objective of this numerical study was to clarify the possibility of predicting pollutant transport in such dynamic and complex hydrologic environments, and to investigate the characteristics of pollutant transport under both naturally occurring and artificially induced groundwater flow (i.e., pumping for remediation). We first tried to reproduce the changes in 1,4-dioxane concentrations in groundwater observed in monitoring wells using a quasi-3D flow and transport simulation considering the multiple sources and spatiotemporal changes in hydrologic conditions. Consequently, we were able to reproduce the long-term trends of concentration changes in each monitoring well. With the predicted pollutant distribution, we conducted simulations for remediation such as pollutant removal using pumping wells. The results of the prediction and remediation simulations revealed the highly complex nature of 1,4-dioxane transport in the dumping site under both naturally occurring and artificially induced groundwater flows. The present study suggests possibilities for the prediction and remediation of pollution at illegal waste dumping sites, but further extensive studies are encouraged for better prediction and remediation.

SYNOPSIS: In this study, we examine audit fees for SEC registrants that remediate previously disclosed material weaknesses in internal control. We find that remediating firms have lower audit fees when compared to firms that continue to report material weaknesses in internal control. However, the remediating firms continue to pay, in the year of remediation as well as one and two years subsequent to remediation, a significant audit fee premium compared to firms that have clean Section 404 reports in each of the first four years. Firms that had an adverse Section 404 report only in the first year, but remediated the problems in year two and had clean Section 404 reports in years three and four, pay an audit fee premium of 32 (21) percent in the third (fourth) year when compared to firms that had clean Section 404 reports in each of the first four years. The results, thus, suggest that audit fees are “sticky” for firms that have material weaknesses in internal controls over financial reporting, and suggest some interesting questions for future research.

Texto completo da fonteResumo:
The contamination of soil by anthropogenic activities is of great concern in recent times. There is an urgent demand of reliable and eco-friendly approaches for remediation of this concern. The current techniques for heavy metal remediation from contaminated soil are costly, time consuming, and harmful for the environment. Toxicity of heavy metals can reduce plant growth, and a high level of presence of these heavy metals is a risk factor to human and plant health. Heavy metals neither biodegradable materials nor are created. They occur naturally in the earth crust, and they reach the environment by human activities. Organic compounds can be degraded, but metals cannot degrade, and therefore effective cleanup requires its immobilization to reduce or remove toxicity. Recently, research focuses on cost-effective technologies to clean polluted areas. Vermiremediation and phytoremediation are two such useful techniques. In these eco-friendly techniques of remediation, the target plants accumulate, volatilize the contaminants, or convert them into some nontoxic forms, thus remediating the soil.

Soil is a very vital necessity to the ecosystem and human population. Due to the urbanization and industrialization, the quality and the fertility of soil is deteriorating. This has been a huge concern among countries to discover the suitable yet effective solution to remediate the soil as the contaminated soil may introduce unhealthy and unsafe environment to society. One of the common pollutants in soils are heavy metals and it is very challenging to remediate as it is not biodegradable materials. Remediation methods for metals can be classified to two categories; in-situ remediation and ex-situ remediation. Studies show that chemical remediation the most effective methods used. Chemical remediation and biological remediation are also another two available options. Chemical remediation methods can be categorized into four; chemical leaching, chemical fixation, electrokinetic remediation and vitrify technology. Biological remediation includes phytoremediation, bioremediation and the combination of the remediation are one of the most cost effective methods that can be implemented especially in poor and middle income countries as it involves natures such as plants and animals in the process

With the acceleration of the process of agricultural modernization, many pesticides (insecticides, fungicides, and herbicides) are applied to the field and finally brought into the soils, causing serious damage to the environment. The problem of pesticide pollution has become increasingly prominent. This has highlighted the urgent need for effective and efficient remediation treatment technology for pesticide-contaminated soils. Biochar has a high specific surface area, high porosity, and strong adsorption capacity, making it a soil amendment agent and carbon fixation agent that can improve soil health and enhance adsorption capacity for pesticides to remediate contaminated soils. Recently, efforts have been made to enhance the physicochemical and adsorption properties of biochar by preparing modified biochar, and it has been developed to expand the application of biochar. Specifically, the following aspects were reviewed and discussed: (i) source and modification methods of biochar for pesticide remediation; (ii) the effect of biochar on the environmental fate of remediating pesticides; (iii) the effect of biochar on pesticide-contaminated soils; and (iv) potential problems for the large-scale promotion and application of biochar remediation of pesticides. In conclusion, this review may serve as a reference and guide for pesticide remediation, hence reducing the environmental concerns associated with pesticides in soil.

The provision of safe water for people is a human right; historically, a major number of people depend on groundwater as a source of water for their needs, such as agricultural, industrial or human activities. Water resources have recently been affected by organic and/or inorganic contaminants as a result of population growth and increased anthropogenic activity, soil leaching and pollution. Water resource remediation has become a serious environmental concern, since it has a direct impact on many aspects of people’s lives. For decades, the pump-and-treat method has been considered the predominant treatment process for the remediation of contaminated groundwater with organic and inorganic contaminants. On the other side, this technique missed sustainability and the new concept of using renewable energy. Permeable reactive barriers (PRBs) have been implemented as an alternative to conventional pump-and-treat systems for remediating polluted groundwater because of their effectiveness and ease of implementation. In this paper, a review of the importance of groundwater, contamination and biological, physical as well as chemical remediation techniques have been discussed. In this review, the principles of the permeable reactive barrier’s use as a remediation technique have been introduced along with commonly used reactive materials and the recent applications of the permeable reactive barrier in the remediation of different contaminants, such as heavy metals, chlorinated solvents and pesticides. This paper also discusses the characteristics of reactive media and contaminants’ uptake mechanisms. Finally, remediation isotherms, the breakthrough curves and kinetic sorption models are also being presented. It has been found that groundwater could be contaminated by different pollutants and must be remediated to fit human, agricultural and industrial needs. The PRB technique is an efficient treatment process that is an inexpensive alternative for the pump-and-treat procedure and represents a promising technique to treat groundwater pollution.

This publication presents the results of studies on the use of a composite sorbent for the remediation of oil-contaminated soils in the Arctic Region. A complex sorbent based on sphagnum moss (Sphagnum L.) was used as a remediator, and the source of the microbiological component adapted to work in low-temperature conditions were microorganisms in activated sludge obtained at water treatment facilities in the Murmansk Region. It is shown that remediation using a complex sorbent at a temperature of 10 °C allows for a reduction in the residual content of oil products in contaminated soil from 100 g/kg to values below 1 g/kg in two months.

ABSTRACT Background Organization and efficiency are central to success on busy inpatient services and may be relevant to demonstrating certain milestones. Most residents adopt these skills by observing supervisors and peers. For some, this method of emulation and adaptation does not occur, with the potential for a negative effect on patient care and team morale. Information on effective strategies for remediating organization and efficiency deficits is lacking. Objective We explored the major themes of organization and efficiency referred to the University of Pennsylvania Department of Medicine Early Intervention and Remediation Committee (EIRC), and developed tools for their remediation. Methods Assessments of residents and fellows referred to the EIRC between July 2014 and October 2016 were reviewed for organization and efficiency deficits. Common areas were identified, and an iterative process of learner observations and expert input was used to develop remediation tools. Results Over a 2-year period, the EIRC developed remediation plans for 4% of residents (13 of 342 total residents), and for 1 internal medicine subspecialty fellow. Organization and efficiency was the primary or secondary deficit in more than half of those assessed. Most common deficiencies involved admitting a patient efficiently, performing effective prerounding, and composing daily progress notes/presentations. Remediation tools that provided deconstruction of tasks to their most granular and reproducible components were effective in improving performance. Conclusions Deficits in organization and efficiency can disproportionately affect resident performance and delay milestone achievement. Many residents would benefit from detailed frameworks and assistance with new approaches to basic elements of daily work.

These issues threaten the health of our planet and its inhabitants. There is a pressing need for innovative strategies to remediate degraded environments and promote sustainable biodiversity. This presentation explores the question: What innovative strategies can be employed to promote sustainable environmental biodiversity and remediate degraded environments? This research employs a comprehensive review of existing literature on environmental remediation and biodiversity conservation. Case studies of successful remediation projects from around the world were explored to identify effective strategies and best practices. The research highlights several innovative strategies for promoting sustainable environmental biodiversity and remediating degraded environments: the use of eco-friendly technologies such as bioremediation, phytoremediation, and green infrastructure; the adoption of circular economy approaches such as waste reduction, reuse, and recycling to minimize waste; the importance of community-led conservation initiatives, and the need for effective policy and governance frameworks to support sustainable environmental biodiversity and remediation efforts. The research has significant implications for policymakers, practitioners, and communities seeking to promote sustainable environmental biodiversity and remediate degraded environments. The innovative strategies highlighted in this research offer a roadmap for sustainable environmental management and biodiversity conservation. This presentation concludes that promoting sustainable environmental biodiversity and remediating degraded environments require innovative strategies that prioritize eco-friendly technologies, circular economy approaches, community-led conservation, and effective policy and governance frameworks. The presentation recommends that the policymakers and practitioners should prioritize the implementation of the innovative strategies.

The remediation methods of heavy metal contaminated soil can be divided into bioremediation, physical remediation and chemical remediation. Chemical remediation mainly includes soil leaching and chemical curing. There are two kinds of soil leaching remediation methods: in situ soil leaching remediation and ectopic leaching remediation. The eluent of heavy metals in soil includes inorganic eluent, chelating agent, surfactant and so on. Soil leaching can be applied to the remediation of contaminated soil alone or combined with other remediation methods.

Background An underperforming doctor puts patient safety at risk. Remediation is an intervention intended to address underperformance and return a doctor to safe practice. Used in health-care systems all over the world, it has clear implications for both patient safety and doctor retention in the workforce. However, there is limited evidence underpinning remediation programmes, particularly a lack of knowledge as to why and how a remedial intervention may work to change a doctor’s practice. Objectives To (1) conduct a realist review of the literature to ascertain why, how, in what contexts, for whom and to what extent remediation programmes for practising doctors work to restore patient safety; and (2) provide recommendations on tailoring, implementation and design strategies to improve remediation interventions for doctors. Design A realist review of the literature underpinned by the Realist And MEta-narrative Evidence Syntheses: Evolving Standards quality and reporting standards. Data sources Searches of bibliographic databases were conducted in June 2018 using the following databases: EMBASE, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Education Resources Information Center, Database of Abstracts of Reviews of Effects, Applied Social Sciences Index and Abstracts, and Health Management Information Consortium. Grey literature searches were conducted in June 2019 using the following: Google Scholar (Google Inc., Mountain View, CA, USA), OpenGrey, NHS England, North Grey Literature Collection, National Institute for Health and Care Excellence Evidence, Electronic Theses Online Service, Health Systems Evidence and Turning Research into Practice. Further relevant studies were identified via backward citation searching, searching the libraries of the core research team and through a stakeholder group. Review methods Realist review is a theory-orientated and explanatory approach to the synthesis of evidence that seeks to develop programme theories about how an intervention produces its effects. We developed a programme theory of remediation by convening a stakeholder group and undertaking a systematic search of the literature. We included all studies in the English language on the remediation of practising doctors, all study designs, all health-care settings and all outcome measures. We extracted relevant sections of text relating to the programme theory. Extracted data were then synthesised using a realist logic of analysis to identify context–mechanism–outcome configurations. Results A total of 141 records were included. Of the 141 studies included in the review, 64% related to North America and 14% were from the UK. The majority of studies (72%) were published between 2008 and 2018. A total of 33% of articles were commentaries, 30% were research papers, 25% were case studies and 12% were other types of articles. Among the research papers, 64% were quantitative, 19% were literature reviews, 14% were qualitative and 3% were mixed methods. A total of 40% of the articles were about junior doctors/residents, 31% were about practicing physicians, 17% were about a mixture of both (with some including medical students) and 12% were not applicable. A total of 40% of studies focused on remediating all areas of clinical practice, including medical knowledge, clinical skills and professionalism. A total of 27% of studies focused on professionalism only, 19% focused on knowledge and/or clinical skills and 14% did not specify. A total of 32% of studies described a remediation intervention, 16% outlined strategies for designing remediation programmes, 11% outlined remediation models and 41% were not applicable. Twenty-nine context–mechanism–outcome configurations were identified. Remediation programmes work when they develop doctors’ insight and motivation, and reinforce behaviour change. Strategies such as providing safe spaces, using advocacy to develop trust in the remediation process and carefully framing feedback create contexts in which psychological safety and professional dissonance lead to the development of insight. Involving the remediating doctor in remediation planning can provide a perceived sense of control in the process and this, alongside correcting causal attribution, goal-setting, destigmatising remediation and clarity of consequences, helps motivate doctors to change. Sustained change may be facilitated by practising new behaviours and skills and through guided reflection. Limitations Limitations were the low quality of included literature and limited number of UK-based studies. Future work Future work should use the recommendations to optimise the delivery of existing remediation programmes for doctors in the NHS.
