Abstract:
... Metal-organic frameworks (MOFs) are promising new materials that have been intensively studied and possibly applied to various environmental remediation. However, little is known about the fate and risk of MOFs to living organisms in the water environment. Here, the toxic effects of ZIF-8 nanoparticles (NPs) on benthic organisms were confirmed by sub-chronic toxicity experiments (7 and 14 days) us ...
... Photooxidative removal of pharmaceuticals and organic dyes is an effective way to eliminate growing micropollutants. However, photooxidation often results in byproducts as secondary hazardous substances such as phytotoxins. Herein, we found that photooxidation of common antibiotic tetracycline hydrochloride (TCH) over a metal-free 8-hydroxyquinoline (8-HQ) functionalized carbon nitride (CN) photoc ...
... An international effort to restore contaminated areas across the Great Lakes has been underway for over 50 years. Although experts have increasingly recognized the inherent connections between ecological conditions and community level benefits, Great Lakes community revitalization continues to be a broad and complex topic, lacking a comprehensive definition. The purpose of this study was to genera ...
... Pollution by microplastics (MPs) formed by the physicochemical breakdown of plastics are a worldwide issue with long-lasting and hazardous natural effects. The natural expulsion of MPs takes several years and can be dangerous. Several effective technological innovations have been developed over the years to remediate harmful MPs. Among them, a blend of nanotechnological techniques using bionanomat ...
... Bioreduction of mobile Cr(VI) to sparingly soluble Cr(III) is an effective strategy for in situ remediations of Cr contaminated sites. The key of this technology is to screen Cr(VI)-resistant bacteria and further explore the sustainable enhancement approaches towards their Cr(VI) reduction performance. In this study, a total of ten Cr(VI)-resistant bacteria were isolated from a Cr(VI) contaminated ...

Abstract:
... Organic-contaminated soils are a major health issue because pollutants can be transferred to waters, air, and living organisms. Many remediation technologies have been developed, yet single methods are usually not fully efficient due to the wide diversity of soil and pollutant properties. Therefore, combining several methods has recently shown wider application range, higher efficiency, and better ...

Abstract:
... Recently, the core–shell nanostructured materials have gained considerable attention due to their nano-scale size effect, well-controlled structure, and tunable physicochemical features which extend their applications in many hot research topics. This review emphasizes their applications in terms of five major fields: catalysis, adsorption, sensing, membrane separation and biomedical application, ...

Abstract:
... A subtle flower-like MIL-125-NH₂@BiOI was fabricated by a facile solvothermal method for simultaneously eliminating Cr(VI)/tetracycline mixed pollutants under visible light. The strong interaction between amino in MIL-125-NH₂ and Bi³⁺ of BiOI promotes the formation of this unique inlaid structure and enables the favorable contact between MIL-125-NH₂ and BiOI, thus accelerating the transfer of char ...

Abstract:
... Metals discharged from abandoned mines are a major source of pollution in many parts of the world. As a result, there is a growing need for suitable low-cost remediation methods. While a large literature base exists demonstrating the efficacy of biochar to remove metals from solution, most studies are confined to the laboratory. This study examines the effects on the biochar quality when scaling u ...

Abstract:
... Despite its remarkable geomorphological, ecological, and touristic value, the coastal sector of the Apulia region (Southern Italy) hosts three of the main contaminated Italian sites (Sites of National Interest, or SINs), for which urgent environmental remediation and reclamation actions are required. These sites are affected by intense coastal modification and diffuse environmental pollution due t ...

Abstract:
... S(IV)-based advanced oxidation process has been applied for contaminants remediation. However, as a traditional source of sulfite (SO₃²⁻), Na₂SO₃ is extremely soluble in water, resulting in a high concentration of SO₃²⁻ to quench the generated reactive oxygen species (ROS). In this work, CaSO₃ was introduced instead of Na₂SO₃ for its slow-released SO₃²⁻ ability and Fe(III)/CaSO₃ system was establi ...

Abstract:
... Over the past three decades, groundwater remediation using permeable reactive barriers (PRBs) has proven to be effective. The majority of installed PRBs uses metallic iron (Fe(0)) as a reactive material. However, the success of implemented Fe(0) PRBs is yet to be rationalized as Fe(0) is a generator of iron oxides (contaminant scavengers) and secondary reducing agents (e.g. Fe(II), Fe₃O₄, H₂, gree ...

... Soil washing is widely considered as a common method of soil remediation. This study examined the developments in soil washing during the past 20 years via a bibliometric and systematic critical review. Different washing agents (inorganic and organic chelating agents and surfactants) exhibit different effects and mechanisms under varying conditions. Most previous research has involved only laborat ...

Abstract:
... The application of surfactant-enhanced air sparging (SEAS) in heterogeneous aquifers has received increasing attention. In this study, a two-dimensional laboratory visualization device was used to study the migration and distribution mechanism of airflow and the nitrobenzene removal effect in an aquifer with a low-permeability lens during AS and SEAS. Experimental results showed that the surfactan ...

... Fracturing technology that can enhance the delivery of amendments has attracted attention in the remediation of low-permeability contaminated sites. However, there are few works on the enhanced delivery of amendments based on multi-point injection in a fracture-matrix system. This study develops a two-dimensional analytical model for enhanced delivery of amendments in a finite-domain low-permeabil ...
