Abstract Misuse and overuse of antibiotics have contributed to the rise of antimicrobial resistance as one of the top public health threats. Antibiotics and antibiotic resistance genes (ARGs) are prevalent in agricultural soils due to the widespread application of livestock and organic wastes. However, information about the occurrence, distribution, and risk of antibiotics and ARGs in agricultural soils is lacking for many scenarios. In this study, based on 2225 observations from 135 independent studies, we summarized the concentration or abundance of antibiotics or ARGs under different fertilizer sources and land-use patterns, analyzed the contributions of key environmental factors to the occurrence of antibiotics and ARGs in agricultural soils, and highlighted the potential ecological risk of typical antibiotics and the relationship between ARGs and mobile genetic elements (MGEs). Our results showed that cattle manure, chicken manure, swine manure, and sewage sludge were the primary pollution sources of antibiotics and ARGs in agricultural soils, and sulfonamides, tetracyclines, fluoroquinolones, and their corresponding ARGs were the main pollution types. Land-use type, soil, and climatic factors affected antibiotics concentration and ARG abundances. MGEs play a vital role in promoting the dissemination of ARGs, especially the sul1 gene is closely related to intI1. In conclusion, our findings and future research exploring these topics will contribute to better management of antibiotic and ARG contamination in agricultural soils and their risk to human health.

Abstract The electro-Fenton (EF) process is a powerful electrochemical advanced oxidation process. Its development has progressed over the past three decades as a clean and effective technique for wastewater treatment. Even though conventional EF has been shown to be a powerful process for efficient degradation/mineralization of toxic and/or persistent organic pollutants; it still suffers from some downsides for industrial-scale development. Recently, research has focused on improving its effectiveness and relevance, mainly by modifying certain operating parameters; improvements in electrode material and reactor configuration, as well as coupling with other treatment methods. Therefore, this review evaluates the current state of the EF process and presents the most recent advances such as 3D-EF, chelate-EF, self-powered EF, pulsed current EF, bio-EF, sono-EF, sulfite-EF, pyrite-EF, and ferrate-EF in addition to its emerging applications like disinfection, generation of value-added products, and removal of emerging pollutants from water. The suitability of different modified or hybrid-EF processes is discussed based on their performance in H2O2 generation, degradation kinetics, mineralization efficiency and cost effectiveness. This review article is intended to be comprehensive, critical and of general interest, covering recent developments and advances in EF process with the aim of providing a powerful method for the treatment of wastewater polluted with biorecalcitrant pollutants.

Abstract Anthropogenic warming of the atmosphere is one if not the most pressing challenge we face in the 21st century. While our state of knowledge on human drivers of atmospheric warming is advancing rapidly, little so can be said if we turn our view toward the Earth’s interior. Intensifying land use and atmospheric climate change condition the changing thermal state of the subsurface at different scales and intensities. Temperature is proven to be a driving factor for the quality of our largest freshwater resource: groundwater. But there is only insufficient knowledge on which sources of heat exist underground, how they relate in their intensity of subsurface warming, and which consequences this warming implies on associated environments, ecosystems and resources. In this review, we propose a differentiated classification based on (1) the geometry of the heat source, (2) the scale at which the subsurface is heated, (3) the process that generates the heat, and (4) the intention of heat release. Furthermore, we discuss the intensities of subsurface warming, the density of induced heat fluxes, as well as their abundance, and draw implications for depending processes and ecosystems in the subsurface and the potential of recycling this waste heat with geothermal installations.

Abstract Organophosphate esters (OPEs) widely exist in the environment, raising increasing concerns about their potential health risks. This comprehensive review surveyed the occurrence of OPEs over the last decade in indoor microenvironments (i.e. residence, in-vehicle, office, and school/daycare center), outdoors, foodstuffs, drinking water, and human-related specimen (i.e. breast milk and urine) with a view to unraveling age-specific exposure to OPEs. Multiple exposure pathways including inhalation, dermal absorption, dust ingestion, and dietary ingestion were considered to prioritize their relative importance. The results showed that dietary ingestion was the main contributor, followed by dust ingestion, regardless of age. A healthy diet with less contaminated food can effectively reduce OPE intake. OPE concentrations in air and dust followed the sequence of in-vehicle and office > school/daycare center > residence > outdoors. Compared to other indoor settings, exposure in schools/daycare centers and offices contributed to a greater OPE intake in non-adults and adults, respectively. The estimated daily intake of OPEs followed the sequence of infants > toddlers > children > teenagers > adults > elderlies. Overall, OPEs posed low health risks to all age cohorts, but infants were vulnerable and subject to the highest risk, largely attributed to breast milk ingestion. This review highlights the need for more toxicity and bioaccessibility studies on OPE mixtures and metabolites to further refine the health risk assessment of OPEs. Graphical abstract

Abstract Antibiotic resistance is a major threat to human-health and wellbeing. Antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are environmental contaminants that circulate among humans, animals and the environment. In urban areas, wastewater treatment plants are the major recipients of these contaminants. Despite the partial elimination during treatment, final effluents, even after disinfection, contain high doses of ARB&ARG. The consequent continuous discharge of these effluents has important adverse impacts, which are particularly intense in vulnerable and deteriorated receiving environments (e.g., due to pollution, droughts or floods, reduced biodiversity). ARB&ARGs are biological contaminants capable of self-replication and horizontal gene-transfer, capabilities that due to pollution-induced selective pressure effects or absence of competition can be enhanced in deteriorated environments. Moreover, as other contaminants, ARB&ARGs can be transported, mainly through water, increasing the risks of circling back as a source of exposure to humans. The current knowledge about antibiotic resistance implications in terms of environmental contamination and risks to human-health, as well as the advances on wastewater treatment technology and antibiotic resistance quantification methods, support the need and timeliness of implementing regular wastewater monitoring systems. Because no single chemical or microbiological parameter can be used to infer the antibiotic resistance load, its specific monitoring should be part of the parameters used to assess wastewater quality. The definition of minimal requirements and integrated monitoring are essential to map antibiotic resistance at time- and space scales, and to design and implement corrective measures. These goals are technically and economically feasible and should be incorporated into wastewater quality directives. Graphical abstract

Abstract Ultrasonically activated persulfate ( , PS) or peroxymonosulfate (HS , PMS) processes have sparked a lot of interest in the degradation of emerging contaminants in the recent years, because of their excellent potential and adaptability. In this review, the synergistic effects of ultrasound (US) and other activating agents such as heat, ultraviolet light (UV), electricity, and heavy metals were analyzed in order to make recommendations for commercial exploitation. Several designs of ultrasonic reactors in the direct or indirect mode of operation were discussed with possible use in the activation of PS/PMS for the degradation of refractory compounds. Applications of suitable sonoreactor configurations for PS/PMS activation in water treatment, disinfection, wastewater treatment (synthetic/real wastewater), soil, and sludge treatment were presented. It has been elucidated that the selection of optimized designs of sonoreactor considering the various parameters including geometric (type of acoustic device, number of transducers, configuration/arrangement of transducers) and operating parameters (power dissipation, irradiating frequency, duty cycle) is important to maximize the efficacy for PS/PMS activation. A systematic insight into the mechanism of US and PS/PMS combination as well as the synergistic effect of US/other activating agents on PS/PMS activation is also highlighted in this review. The work has clearly elucidated the key process intensification benefits in terms of higher oxidation capacity, reduced treatment times and cost of operation based on expected synergism in various combinations.

Abstract Cellulose nanomaterials are low cost, biocompatible and readily combined with other materials to produce nanocomposites with a range of applications. Cellulose nanomaterials have many advantageous properties, including high mechanical and thermal stability, high specific surface area, and biodegradability. The highly flexible cellulose structure can be exploited to transform bulk cellulose into isolated nanostructured fibers that retain the original thermal, mechanical, and optical properties of the bulk material. In this review, we highlight recent advances in the environmental application of cellulose nanocomposites. We introduce the different chemical, mechanical, and biological pathways used for preparation of cellulose nanomaterials. Recent rapid technological advancements in the preparation of cellulose nanocomposites by combining metal nanoparticles, organic polymers, and metal-organic frameworks (MOFs) with cellulose are then discussed. Finally, we summarize the latest progress in the application of cellulose nanocomposites in environmental science and engineering and provide a perspective on the future outlook of cellulose nanocomposites.

Abstract Far UV-C, informally defined as electromagnetic radiation with wavelengths between 200 and 230 nm, has characteristics that are well-suited to control of airborne pathogens. Specifically, Far UV-C has been shown to be highly effective for inactivation of airborne pathogens; yet this same radiation has minimal potential to cause damage to human skin and eye tissues. Critically, unlike UV-B, Far UV-C radiation does not substantially penetrate the dead cell layer of skin (stratum corneum) and does not reach germinative cells in the basal layer. Similarly, Far UV-C radiation does not substantially penetrate through corneal epithelium of the eye, thereby preventing exposure of germinative cells within the eye. The most common source of Far UV-C radiation is the krypton chloride excimer (KrCl*) lamp, which has a primary emission centered at 222 nm. Ozone production from KrCl* lamps is modest, such that control of indoor ozone from these systems can be accomplished easily using conventional ventilation systems. This set of characteristics offers the potential for Far UV-C devices to be used in occupied spaces, thereby allowing for improved effectiveness for inactivation of airborne pathogens, including those that are responsible for COVID-19.

Abstract Layered double hydroxides (LDHs) and LDHs-derived materials are emerging as potential engineered adsorbents for the protection of water environment. Particularly, LDHs intercalated with different guest compounds (GC-LDHs), which differ from traditional interlayer anions (such as Cl−, SO4 2−, NO3 −, CO3 2−, and PO4 3−), are widely reported by recent studies showing their promising multifunctional roles in water purification. Herein, this review systematically presents the synthesis methods and characterization techniques of GC-LDHs and their application as adsorbents in removing potentially toxic elements (PTEs) from the aqueous phase. This review also elaborates on the important roles of complexation, chelation, precipitation, isomorphic substitution, and ion exchange in the process of PTE removal by GC-LDHs. Among them, compared with PTE cations, ion exchange is an additional mechanism for the removal of PTE oxyanions by GC-LDHs. Furthermore, the influence of pH, ionic strength, temperature, physiochemical properties of original LDHs and guest compounds on the GC-LDHs adsorption performance are also summarized.

Particularly, LDHs intercalated with different guest compounds (GC-LDHs), which differ from traditional interlayer anions (such as Cl−, SO4 2−, NO3 −, CO3 2−, and PO4 3−), are widely reported by recent studies showing their promising multifunctional roles in water purification.

This review also elaborates on the important roles of complexation, chelation, precipitation, isomorphic substitution, and ion exchange in the process of PTE removal by GC-LDHs. Among them, compared with PTE cations, ion exchange is an additional mechanism for the removal of PTE oxyanions by GC-LDHs. Furthermore, the influence of pH, ionic strength, temperature, physiochemical properties of original LDHs and guest compounds on the GC-LDHs adsorption performance are also summarized.

Abstract Natural attenuation is a major ecosystem function allowing to abate soil organic contaminants such as polycyclic aromatic hydrocarbons (PAHs). Biodegradation of PAHs is classically considered as the major driver of natural attenuation, yet the role of abiotic transformation, including photodegradation, chemical oxidation, formation of non-extractable residues, and polymerization, has been overlooked due to the lack of investigations until recently. This paper reviews PAHs dissipation in soils by abiotic processes such as photodegradation and oxidation catalyzed by inorganic minerals and organic matters. The role of soil components on degradation rates, pathways, and mechanisms are discussed. The products of PAHs abiotic transformation and their potential risks are also described. Abiotic transformations are mainly controlled by interactions between PAHs and clay minerals, metal oxides/hydroxides, and soil organic matter. PAH photodegradation proceeds by both direct and indirect photolysis processes, which are enhanced in the presence of natural photosensitizers, for example, organic matter, and photocatalysts, for example, metal oxides/hydroxides. PAHs can also be chemically/catalytically oxidized by metal oxides/hydroxides, for example, MnO2, FexOy, and clay minerals without light irradiation. Overall, PAHs transformation depends on their electron-donating properties, mineral electron-accepting properties, pH, temperature, moisture, and oxygen content. Following the elucidation of the transformative mechanism, knowledge to understand the impact of abiotic transformation on biodegradation are delineated. Future investigations are needed to advance the correlation of laboratory generated rates to the field applications, and the potential applications of natural attenuation based on abiotic processes are proposed.
