Macrophyte rhizospheric dissolved organic matter (ROM) served as widespread abiotic components in aquatic ecosystems, and its effects on antibiotic residues and antibiotic resistance genes (ARGs) could not be ignored. However, specific influencing mechanisms for ROM on the fate of antibiotic residues and expression of ARGs still remained unclear. Herein, laboratory hydroponic experiments for water lettuce (Pistia stratiotes) were carried out to explore mutual interactions among ROM, sulfamethoxazole (SMX), bacterial community, and ARGs expression. Results showed ROM directly affect SMX concentrations through the binding process, while C O and N-H groups were main binding sites for ROM. Dynamic changes of ROM molecular composition diversified the DOM pool due to microbe-mediated oxidoreduction, with enrichment of heteroatoms (N, S, P) and decreased aromaticity. Microbial community analysis showed SMX pressure significantly stimulated the succession of bacterial structure in both bulk water and rhizospheric biofilms. Furthermore, network analysis further confirmed ROM bio-labile compositions as energy sources and electron shuttles directly influenced microbial structure, thereby facilitating proliferation of antibiotic resistant bacteria (Methylotenera, Sphingobium, Az spirillum) and ARGs (sul 1, sul 2, intl 1). This investigation will provide scientific supports for the control of antibiotic residues and corresponding ARGs in aquatic ecosystems. [Display omitted] • Amide and amino groups in ROM are main binding sites for sulfamethoxazole. • ROM bio-labile compositions are closely linked to microbial metabolisms. • ROM fractions favored the formation of rhizospheric biofilms. • SMX pressure stimulated the succession of bacterial community. • Rhizospheric biofilms offered favorable microenvironments for ARB development.

[Display omitted] Heavy metal pollution in water bodies is a serious environmental problem continuously, which requires urgently seeking an efficient and cost-effective solution. Apatite as the most abundant phosphate on earth exhibits remarkable adsorption effect on heavy metals. Based on this, three kinds of apatite adsorbents were prepared in this study by titration co-precipitation method for the removal of heavy metals Pb (II) and Cd (II) from water. In the single system, the maximum adsorption capacity of hydroxyapatite (Hap), chlorapatite (Clap), and fluorapatite (Fap) for Pb (II) was 1597.16 mg/g, 1477.82 mg/g, and 1455.99 mg/g, for Cd (II) were Hap (107.18 mg/g), Clap (79.08 mg/g) and Fap (15.8 mg/g). Pb (II) was more competitive than Cd (II) in binary metal system. Apatite adsorbents mainly remove Pb (II) and Cd (II) from solution by dissolution precipitation, electrostatic attraction, surface complexation and ion exchange. The results of this study show that the three kinds of apatite adsorbents exhibited excellent adsorption performance for Pb (II), and also had a certain removal effect for Cd (II). Therefore, the three kinds of apatite have certain application prospects in heavy metal wastewater treatment. [ABSTRACT FROM AUTHOR]

Poly- and perfluoroalkyl substances (PFASs) are a group of emerging organic contaminants which are persistent to normal physicochemical treatments. The widespread use of PFASs has caused significant environmental issues. The bioaccumulation and distribution of PFASs within plant compartments have revealed great potentials for phytoremediation. In this review, the roles of aquatic plants in the process of PFASs remediation were highlighted. Moreover, there were different underlying mechanisms of PFASs uptake between terrestrial and aquatic plants. On the other hand, a wide range of influencing factors for bioaccumulation and translocation of PFASs within plant compartments are also presented and discussed. In response to exposure of PFASs, corresponding phytotoxic effects has affected the growth and metabolism of plants, which could provide beneficial guides of the phytotoxic tolerance for plant species selection in applications of phytoremediation. Finally, the discussion about whether phytoremediation is a viable option for PFASs removal and further research priorities are suggested. [Display omitted] • The mechanism for plant uptake of PFASs has been comprehensively reviewed. • There are different mechanisms of PFASs uptake between terrestrial and aquatic plants. • Influencing factors for plant uptake and root adsorption of PFASs were introduced. • The feasibility of phytoremediation in PFASs site remediation has been critically discussed.

Using carbon-based materials (CBMs) to facilitate phytoremediation shows great promise for simultaneously enhancing the restoration efficiency of contaminated soil and reducing carbon dioxide in the context of global warming, which is still in the exploring and attempting phase. In addition to direct degradation or alteration of pollutant bioavailability, CBMs can enhance phytoremediation by alleviating plant nutrient deprivation and oxidative stress, as well as by modulating soil microbial communities and root secretions. Photosynthetic carbon fixation predominantly affects both phytoremediation efficiency and carbon cycle turnover in terrestrial ecosystems. In this regard, CBMs have extremely positive properties in facilitating plant carbon capture, with intrinsic mechanisms including (1) promoting photosynthetic pigment synthesis and acting as artificial built-in antennae to improve photon capture efficiency, (2) accelerating the photosynthetic electron transport rate in photosystems, (3) improving the Calvin cycle, and (4) maintaining the structural integrity of chloroplasts. Besides, as an ultra-stable type of CBM derived from waste biomass, biochar can preserve the native biomass carbon in the soil environment for decades and attenuate the rhizosphere priming effect by influencing the structure of rhizosphere soil aggregates and microbial communities, thus retarding the native soil organic carbon efflux. This review critically elaborates on the mechanisms by which CBMs assist in improving the efficiency of phytoremediation and their positive effects on the plant-root soil carbon balance. Additionally, a simple full-life cycle analysis encompassing cost analysis as well as ecological, economic, and social benefits is concluded to evaluate the feasibility and sustainability of CBMs-phytoremediation systems.

[Display omitted] The coexistence of antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in the environment poses a potential threat to public health. In our study, we have developed a novel advanced oxidation process for simultaneously removing ARGs and ARB by two types of iron and nitrogen-doped biochar derived from rice straw (FeN-RBC) and sludge (FeN-SBC). All viable ARB (approximately 108 CFU mL−1) was inactivated in the FeN-RBC/ peroxymonosulfate (PMS) system within 40 min and did not regrow after 48 h even in real water samples. Flow cytometry identified 96.7 % of dead cells in the FeN-RBC/PMS system, which verified the complete inactivation of ARB. Thorough disinfection of ARB was associated with the disruption of cell membranes and intracellular enzymes related to the antioxidant system. Whereas live bacteria (approximately 200 CFU mL−1) remained after FeN-SBC/PMS treatment. Intracellular and extracellular ARGs (tetA and tetB) were efficiently degraded in the FeN-RBC/PMS system. The production of active species, primarily •OH, SO 4 •- and Fe (IV), as well as electron transfer, were essential to the effective disinfection of FeN-RBC/PMS. In comparison with FeN-SBC, the better catalytic performance of FeN-RBC was mainly ascribed to its higher amount of pyridine-N and Fe0, and more reactive active sites (such as C O group and Fe-N sites). Density functional theory calculations indicated the greater adsorption energy and Bader charge, more stable Fe-O bond, more easily broken O O bond in FeN-RBC/PMS, which demonstrated the stronger electron transfer capacity between FeN-RBC and PMS. To encapsulate, our study provided an efficient and dependable method for the simultaneous elimination of ARGs and ARB in water. [ABSTRACT FROM AUTHOR]

[Display omitted] Recently, carbon materials have attracted much attention in activating persulfate (PS) for the removal of organic pollutants. Seeking a greener, lower-cost, and higher-performance carbon material has become an important aspect of research. In this study, candle soot was innovatively used as a nanocarbon material, and its performance for PS activation was improved by simple ammonium ferric citrate modification. The optimal catalytic performance was achieved using 0.15 g/L modified candle soot (AS) and only 0.1 mM PS, with sulfamethoxazole (SMX) removal efficiency up to 95.5% within 120 min. Quenching tests, together with electron paramagnetic resonance measurements, showed that O 2 − and 1O 2 were the main reactive species for SMX degradation. Meanwhile, electron transfer pathway was also occurred. Various characterization results showed that graphitic N and carbonyl group were the main active sites for PS activation. Moreover, AS/PS system exhibited high catalytic activity and stability for SMX degradation over a wide initial pH range (3∼9), or even in the presence of Cl−, H 2 PO 4 − and NO 3 −. This work not only taps the potential of candle soot as an environmental functional material, but also showcases the roadmap for the discovery, design, and resource utilization of other waste carbon materials in wastewater treatment.

• Pollutants were degraded more efficiently via peracetic acid activation by S-nZVIC. • Doped Cu0 and sulfidation induced transition of dominant radicals from R-O• to •OH. • The regeneration of Fe(Ⅱ) was promoted by Cu(Ⅰ)/Cu(Ⅱ) cycle provided by Cu0. • The relative contribution rate of R-O• decreased with S/Fe ratio increasing. • Sulfidation promoted the electron transfer from S-nZVIC to peracetic acid. Peracetic acid (PAA) has emerged as a new effective oxidant for various contaminants degradation through advanced oxidation process (AOP). In this study, sulfidated nano zero-valent iron-copper (S-nZVIC) with low Cu doping and sulfidation was synthesized for PAA activation, resulting in more efficient degradation of sulfamethoxazole (SMX, 20 μM) and other contaminants using a low dose of catalyst (0.05 g/L) and oxidant (100 μM). The characterization results suggested that S-nZVIC presented a more uniform size and distribution with fewer metal oxides, as the agglomeration and oxidation were inhibited. More significantly, doped Cu0 and sulfidation significantly enhanced the generation and contribution of •OH but decreased that of R-O• in S-nZVIC/PAA/SMX system compared with that of nZVIC and S-nZVI, accounting for the relatively high degradation efficiency of 97.7% in S-nZVIC/PAA/SMX system compared with 85.7% and 78.9% in nZVIC/PAA/SMX and S-nZVI/PAA/SMX system, respectively. The mechanisms underlying these changes were that (i) doped Cu° could promote the regeneration of Fe(Ⅱ) for strengthened PAA activation through mediating Fe(Ⅱ)/Fe(Ⅲ) cycle by Cu(Ⅰ)/Cu(Ⅱ) cycle; (ii) S species might consume part of R-O•, resulting in a decreased contribution of R-O• in SMX degradation; (iii) sulfidation increased the electrical conductivity, thus facilitating the electron transfer from S-nZVIC to PAA. Consequently, the dominant reactive oxygen species transited from R-O• to •OH to degrade SMX more efficiently. The degradation pathways, intermediate products and toxicity were further analyzed through density functional theory (DFT) calculations, liquid chromatography-mass spectrometry (LC-MS) and T.E.S.T software analysis, which proved the environmental friendliness of this process. In addition, S-nZVIC exhibited high stability, recyclability and degradation efficiency over a wide pH range (3.0∼9.0). This work provides a new insight into the rational design and modification of nano zero-valent metals for efficient wastewater treatment through adjusting the dominant reactive oxygen species (ROS) into the more active free radicals.

[Display omitted] Unevenly distributed polypyrrole (PPy) films/coatings with extensive "dead volumes" via electrodeposition have emerged as a main challenge for high energy density flexible supercapacitor. In this work, we have fabricated a phytic acid-guided graphite carbon felt/polypyrrole (GF@PA@PPy) 3D porous composite with less "dead volumes" via electrodeposition. After the activation of phytic acid (PA), the quantity and content of defects and oxygen-containing groups on the surface of carbon felt (GF) have increased. First, these functional groups improve the hydrophilicity of the surface of GF, resulting in the preferential uniform distribution of pyrrole monomer (Py). While significantly, the synergistic effects between the defects and oxygen-containing groups boost the attraction of pyrrole ring, and thus promotes the formation of perfect PPy films with less "dead volume" on GF. Finally, the supercapacitor assembled from the GF@PA@PPy-40 displays a high areal energy density of 0.0732 mWh cm−2, exceeding the previously reported PPy-based electrodes values. The deeper understanding of the role for the defects and oxygen-containing groups in the synthesis of PPy/carbon materials offers a new strategy to construct advanced PPy-based supercapacitors.

[Display omitted] • The synthesis methods to incorporate N into zero-valent and atomic iron are systematically summarized. • The form of N and Fe changes after the incorporation of N. • The FeNx species play an important role in contaminants transformation. • The zero-valent and atomic iron after the incorporation of N can be promising materials for environmental application. The FeN x active species in Fe-N materials after the incorporation of N into zero-valent and atomic iron showed excellent performance on contaminants transformation compared with the materials before modification. However, the research of FeN x on the environmental field is still in the preliminary stage at present. In view of the enormous potential, this article emphasizes the research advances in the incorporation of N into zero-valent and atomic iron for contaminants transformation. Firstly, the synthesis of Fe-N material including synthesis methods, changes in characterization and active species as well as influence factors during the synthesis progress are introduced. Most importantly, the efficiency and mechanism of zero-valent iron after the N incorporation on dechlorination, denitrification and activation of oxidants, and the atomic iron after N incorporation on desulfurization, selective transformation and activation of oxidants are also summarized, where FeN x species play an important role. Additionally, due to the high stability, tolerance, adaptability to various contaminants and less recycling difficulty, the potential of Fe-N materials for practical environmental applications is appreciated. At length, this review discusses the challenges and overlooks in the future, looking forward to providing assistance for utilizing the Fe-N materials to handle the troublesome water contaminants.

• The catalyst activated PDS efficiently with high stability and generalizability. • The complexation of AL with RM favored the exposure of Fe active sites and adsorption of PDS. • The electron transfer pathway was the main pathway for PDS activation and SMZ degradation. • DFT demonstrated that Fe-active species are the primary site where electron transfer occurs. • T.E.S.T and biological experiments predicted lower toxicity of degradation intermediates. Advanced oxidation processes based on peroxydisulfate (PDS-AOPs) have been used for the remediation of organic wastewater. However, the mechanism for the generation of electron transfer sub-stable complexes in the metal–carbon/PDS system has not been fully elucidated. Herein, two environmental solid wastes were selected to synthesize a novel Fe-carbon catalyst (RM@KC 1:2 –800) using alkali lignin as the carrier and red mud (RM) as the iron source, and applied for peroxydisulfate (PDS) activation in sulfamethazine (SMZ) removal. The complexation of alkali lignin with RM favored the exposure of Fe active sites and adsorption of PDS. 97% of SMZ could be removed efficiently in the RM@KC 1:2 –800/PDS system, and the degradation efficiency remained at 80.81% after 5 cycles without metal leaching, which was suitable for a variety of natural water bodies. Combined with density functional theory (DFT) and other analyses confirmed that the electron transfer pathway is the main pathway for PDS activation and SMZ degradation. And the reactive Fe species were the active sites that contributed to the adsorption of PDS on the RM@KC 1:2 –800 surface to form sub-stable complexes (RM@KC-PDS*), whereby the electron transfer occurred. Surprisingly, the prediction of environmental toxicity of the degradation intermediates based on T.E.S.T software and biological experiments proved their environmental friendliness. Overall, this study follows the concept of "waste-to-waste" and proposes a strategy for a suitable and cost-effective Fe-carbon catalyst for large-scale production, while demonstrating its potential application in the treatment of organic wastewater.

• The hydrogenation of FFR to FFA via APR of CH 3 OH using Pt@MT-450 catalyst. • Perfect conversion, selectivity, and recyclability of the catalyst. • The safe, mild condition without external hydrogen gas. It is a promising pathway to reduce the dependence on fossil fuels and obtain the bio-fuels or chemicals production from biomass derivatives. The conversion from furfural (FFR) to furfuryl alcohol (FFA) is an important industrial technology using the liquid-phase hydrogenation method with external hydrogen gas. However, the natural environment is threatened by the security of external hydrogen gas, toxicant catalyst, and the high energy consumption. Recently, in-situ hydrogenation is a novel method to converse FFR to FFA at mild reaction conditions to replace the dangerous external hydrogen gas. In this paper, we reported an efficient in-situ hydrogenation method via aqueous-phase reforming of methanol using Pt loading MgTiO 3 (perovskite-type material) at mild conditions. Pt nanoparticles were high dispersion on the nano-MgTiO 3 -450 surface, and CH 3 OH and H 2 O were reformed to produce hydrogen gas on the catalyst surface through the action of Pt nanoparticles. A part of active hydrogen could be involved in the reduction of Pt2+ to Pt0, resulting in the perfect recyclability of the Pt@MT-450 catalyst. The other part of active hydrogen were participated in the hydrogenation of FFR conversion to FFA under the interaction of Pt and Mg elements. The in-situ hydrogenation of FFR to FFA using Pt@MT-450 is an effectively pathway to reduce the reaction conditions than that with external hydrogen gas. [ABSTRACT FROM AUTHOR]

[Display omitted] • Composting reduced the mobility and bioavailability of Mn. • Phanerochaete chrysosporium enriched microbial community diversity and structure. • Composting achieves passivation of Mn with Phanerochaete chrysosporium inoculation. • The inoculation of Phanerochaete chrysosporium accelerated the temperature rise. Electrolytic manganese residue poses potentially threats to the environment and therefore needs eco-friendly treatment. Composting has been reported to effectively passivate heavy metals and alleviate their ecotoxicity. Observation of the Mn concentration during composting indicated that the mobility of Mn was significantly reduced, with the easily extraction fraction (acid extractable and easily reduction fraction) of Mn in the control pile (pile 1 without Phanerochaete chrysosporium inoculation) and treat pile (pile 2 with Phanerochaete chrysosporium inoculation) decreasing by 17% and 29%, respectively. The inoculation of Phanerochaete chrysosporium prompted the passivation of manganese, prolonged the thermophilic period, and enriched the microbial community structure, which was attributed to the rapid growth and reproduction of thermophilic bacteria. Moreover, Phanerochaete chrysosporium inoculation promoted the effect of pH on the stabilization of Mn, but the opposite contribution of organic matter. This study would provide a new perspective for remediating EMR contaminated soil via composting. [ABSTRACT FROM AUTHOR]

Wastewater treatment plants (WWTPs) are an important source of microplastics (MPs) entering the aquatic environment. As environmental awareness increases, WWTPs are gradually using constructed wetlands (CWs) in the depth treatment stage. There were few studies related to MPs removal efficiency of CWs, especially in multi-stage and multi-combinations CWs. Therefore, we studied MPs characteristics and removal in a typical CWs WWTP in Changsha, comparing the MPs removal efficiencies of different processes in a WWTP, focusing on the MPs abundance variation in different stages CWs. Result showed that the MPs removal efficiency of Phase Ⅰ was 87.72% and that of Phase II was 80.65%. Approximate estimates showed that the daily discharge of MPs reached 7.20 * 108 items. The MPs removal efficiency of vertical flow CWs was 25.71%. The MPs removal efficiencies of secondary and tertiary horizontal subsurface flow CWs (HSSFCWs) were 32.00% and 21.43%. The MPs removal efficiencies of secondary and tertiary surface flow CWs were 23.53% and 12.50%. The MPs removal efficiencies of three bio-ponds were -23.08%, -12.90%, and -27.27%. Combined system of bio-pond + CWs reduced the MPs removal efficiency. The most dominant shape of MPs in wastewater was fibers. The most common MPs were polyethylene and polystyrene. The primary treatment in the Changsha WWTP had the highest MPs removal efficiency. Results of this investigation showed the multi-combination and multi-stage CWs WWTP can remove most of MPs in influent, which greatly reduced the amount of MPs discharged into the aquatic environment through WWTP and provided data for analyzing the distribution of MPs in the aquatic environment. [Display omitted] • MPs removal efficiency of Yanghu reclaimed water plant ranged from 80.65% to 87.72%. • Secondary constructed wetlands (CWs) had the highest MPs removal efficiency in CWs. • MPs removal efficiency of horizontal subsurface flow CWs was higher than other CWs. • MPs removal efficiency of three bio-ponds was negative.

Plastics enter the environment and break up into microplastics (MPs) and even nanoplastics (NPs) by biotic and abiotic weathering. These small particles are widely distributed in the environmental media and extremely mobile and reactive, easily suspending in the air, infiltrating into the soil, and interacting with biota. Current research on MPs/NPs is either in the abiotic or biotic compartments, with little attention paid to the fact that the biosphere as a whole. To better understand the complex and continuous movement of plastics from biological to planetary scales, this review firstly discusses the transport processes and drivers of microplastics in the macroscopic compartment. We then summarize insightfully the uptake pathways of MPs/NPs by different species in the ecological compartment and analyze the internalization mechanisms of NPs in the organism. Finally, we highlight the bioaccumulation potential, biomagnification effects and trophic transfer of MPs/NPs in the food chain. This work is expected to provide a meaningful theoretical body of knowledge for understanding the biogeochemical cycles of plastics. [Display omitted] • The transport of MPs in macroscopic compartments are discussed. • Uptake pathways of MPs/NPs in different biota are summarized. • Different mechanisms of cellular internalization of NPs in organisms are analyzed. • Bioaccumulation potential and biomagnification effects of MPs/NPs are assessed. • Evidence for trophic transfer of MPs/NPs along the food chain is highlighted.

Metal organic frameworks (MOFs) have great potential for photocatalysis, but only possess moderate activity due to their slow charge transfer and low solar energy conversion. Herein, heterostructures photocatalysts constructed by boron nitride quantum dots (BNQDs) and MIL-100(Fe) (MNB) were successfully fabricated for overcoming these shortcomings. It was indicated that the composites possessed large surface area, mesoporous structure, and enhanced visible light absorption. The MNB photocatalysts exhibited excellent photocatalytic activity for tetracycline hydrochloride (TC-HCl) degradation under visible light irradiation. Compared with MIL-100(Fe), the photodegradation rate of TC-HCl by MNB-1 was 0.02383 min−1, which was 5.3 times higher than that of pure MIL-100(Fe). The close contact of MIL-100(Fe) with BNQDs and the synergistic effect between them were the main reasons for the improved photodegradation performance. This study reveals that a rational combination of MIL-100(Fe) and BNQDs can improve photocatalytic activity to enhance molecular oxygen activation. Therefore, it is reasonable to believe that quantum dots/MOFs photocatalysts have great potential in environmental remediation. [Display omitted] [ABSTRACT FROM AUTHOR]
