    查看更多>>摘要：Fenton and Fenton-like processes,which could produce highly reactive species to degrade organic contaminants,have been widely used in the field of wastewater treatment.Therein,the chemistry of Fenton process including the nature of active oxidants,the complicated reactions involved,and the behind reason for its strongly pH-dependent performance,is the basis for the application of Fenton and Fenton-like processes in wastewater treatment.Nevertheless,the conflicting views still exist about the mechanism of the Fenton process.For instance,reaching a unanimous consensus on the nature of active oxidants(hydroxyl radical or tetravalent iron)in this process remains challenging.This review comprehen-sively examined the mechanism of the Fenton process including the debate on the nature of active oxidants,reactions involved in the Fenton process,and the behind reason for the pH-dependent degradation of contaminants in the Fenton process.Then,we summarized several strategies that promote the Fe(Ⅱ)/Fe(Ⅲ)cycle,reduce the competitive consumption of active oxidants by side reactions,and replace the Fenton reagent,thus improving the performance of the Fenton process.Furthermore,advances for the future were proposed including the demand for the high-accuracy identification of active oxidants and taking advantages of the characteristic of target contaminants during the degradation of contam-inants by the Fenton process.

    查看更多>>摘要：Biomineralization has garnered significant attention in the field of wastewater treatment due to its notable cost reduction compared to conventional methods.The reinjection water from oilfields containing an exceedingly high concentration of calcium and ferric ions will pose a major hazard in production.However,the utilization of biomineralization for precip-itating these ions has been scarcely investigated due to limited tolerance among halophiles towards such extreme conditions.In this study,free and immobilized halophiles Virgibacillus dokdonensis were used to precipitate these ions and the effects were compared,at the same time,biomineralization mechanisms and mineral characteristics were further explored.The results show that bacterial concentration and carbonic anhydrase activity were higher when additionally adding ferric ion based on calcium ion;the content of protein,polysaccharides,deoxyribonucleic acid and humic substances in the extracellular polymers also increased compared to control.Calcium ions were biomineralized into calcite and vaterite with mul-tiple morphology.Due to iron doping,the crystallinity and thermal stability of calcium car-bonate decreased,the content of O-C=O,N-C=O and C-O-PO3 increased,the stable carbon isotope values became much more negative,and β-sheet in minerals disappeared.Higher calcium concentrations facilitated ferric ion precipitation,while ferric ions hindered cal-cium precipitation.The immobilized bacteria performed better in ferric ion removal,with a precipitation ratio exceeding 90％.Free bacteria performed better in calcium removal,and the precipitation ratio reached a maximum of 56％.This research maybe provides some ref-erence for the co-removal of calcium and ferric ions from the oilfield wastewater.

    查看更多>>摘要：Heavy metal(loid)(HM)pollution in agricultural soils has become an environmental con-cem in antimony(Sb)mining areas.However,priority pollution sources identification and deep understanding of environmental risks of HMs face great challenges due to multiple and complex pollution sources coexist.Herein,an integrated approach was conducted to distinguish pollution sources and assess human health risk(HHR)and ecological risk(ER)in a typical Sb mining watershed in Southern China.This approach combines absolute prin-cipal component score-multiple linear regression(APCS-MLR)and positive matrix factoriza-tion(PMF)models with ER and HHR assessments.Four pollution sources were distinguished for both models,and APCS-MLR model was more accurate and plausible.Predominant HM concentration source was natural source(39.1％),followed by industrial and agricultural ac-tivities(23.0％),unknown sources(21.5％)and Sb mining and smelting activities(16.4％).Al-though natural source contributed the most to HM concentrations,it did not pose a signif-icant ER.Industrial and agricultural activities predominantly contributed to ER,and atten-tion should be paid to Cd and Sb.Sb mining and smelting activities were primary anthro-pogenic sources of HHR,particularly Sb and As contaminations.Considering ER and HHR assessments,Sb mining and smelting,and industrial and agricultural activities are critical sources,causing serious ecological and health threats.This study showed the advantages of multiple receptor model application in obtaining reliable source identification and provid-ing better source-oriented risk assessments.HM pollution management,such as regulating mining and smelting and implementing soil remediation in polluted agricultural soils,is strongly recommended for protecting ecosystems and humans.

    165-178页
    查看更多>>摘要：In this study,two wheat-derived cadmium(Cd)-immobilizing endophytic Pseudomonas par-alactis M14 and Priestia megaterium R27 were evaluated for their effects on wheat tissue Cd uptake under hydroponic conditions.Then,the impacts of the biochar(BC),M14+R27(MR),and BC+MR treatments on wheat Cd uptake and the mechanisms involved were investi-gated at the jointing,heading,and mature stages of wheat plants under field-plot condi-tions.A hydroponic experiment showed that the MR treatment significantly decreased the above-ground tissue Cd content compared with the M14 or R27 treatment.The BC+MR treat-ment reduced the grain Cd content by 51.5％-67.7％and Cd translocation factor at the ma-ture stage of wheat plants and increased the organic matter-bound Cd content by 31％-75％in the rhizosphere soils compared with the BC or MR treatment.Compared with the BC or MR treatment,the relative abundances of the biomarkers associated with Gemmatimonas,Altererythrobacter,Gammaproteobacteria,Xanthomonadaceae,Phenylobacterium,and No-cardioides in the BC+MR-treated rhizosphere microbiome decreased and negatively corre-lated with the organic matter-bound Cd contents.In the BC+MR-treated root interior mi-crobiome,the relative abundance of the biomarker belonging to Exiguobacterium increased and negatively correlated with the Cd translocation factor,while the relative abundance of the biomarker belonging to Pseudonocardiaceae decreased and positively correlated with the Cd translocation factor.Our findings suggested that the BC+MR treatment reduced Cd availability and Cd transfer through affecting the abundances of these specific biomarkers in the rhizosphere soil and root interior microbiomes,leading to decreased wheat grain Cd uptake in the contaminated soil.

    Remediation mechanism of high concentrations of multiple heavy metals in contaminated soil by Sedum alfredii and native microorganisms

    Zihe WangHan ZhangYing XiongLieyu Zhang...
    179-188页
    查看更多>>摘要：Pollution accident of nonferrous metallurgy industry often lead to serious heavy metal pol-lution of the surrounding soil.Phytoremediation of contaminated soil is an environmental and sustainable technology,and soil native microorganisms in the process of phytoreme-diation also participate in the remediation of heavy metals.However,the effects of high concentrations of multiple heavy metals(HCMHMs)on plants and native soil microorgan-isms remain uncertain.Thus,further clarification of the mechanism of phytoremediation of HCMHMs soil by plants and native soil microorganisms is required.Using the plant Sedum alfredii(S.alfredii)to restore HCMHM-contaminated soil,we further explored the mechanism of S.alfredii and native soil microorganisms in the remediation of HCMHM soils.The results showed that(i)S.alfredii can promote heavy metals from non-rhizosphere soil to rhizo-sphere soil,which is conducive to the effect of plants on heavy metals.In addition,it can also enrich the absorbed heavy metals in its roots and leaves;(ii)native soil bacteria can increase the abundance of signal molecule-synthesizing enzymes,such as trpE,trpG,bjaI,rpfF,ACSL,and yidC,and promote the expression of the pathway that converts serine to cys-teine,then synthesize substances to chelate heavy metals.In addition,we speculated that genes such as K19703,K07891,K09711,K19703,K07891,and K09711 in native bacteria may be involved in the stabilization or absorption of heavy metals.The results provide scientific basis for S.alfredii to remediate heavy metals contaminated soils,and confirm the potential of phytoremediation of HCMHM contaminated soil.

    189-199页
    查看更多>>摘要：China's lowland rural rivers are facing severe eutrophication problems due to excessive phosphorus(P)from anthropogenic activities.However,quantifying P dynamics in a low-land rural river is challenging due to its complex interaction with surrounding areas.A P dynamic model(River-P)was specifically designed for lowland rural rivers to address this challenge.This model was coupled with the Environmental Fluid Dynamics Code(EFDC)and the Phosphorus Dynamic Model for lowland Polder systems(PDP)to characterize P dynam-ics under the impact of dredging in a lowland rural river.Based on a two-year(2020-2021)dataset from a representative lowland rural river in the Lake Taihu Basin,China,the cou-pled model was calibrated and achieved a model performance(R2＞0.59,RMSE＜0.04 mg/L)for total P(TP)concentrations.Our research in the study river revealed that(1)the time scale for the effectiveness of sediment dredging for P control was～300 days,with an increase in P retention capacity by 74.8 kg/year and a decrease in TP concentrations of 23％after dredg-ing.(2)Dredging significantly reduced P release from sediment by 98％,while increased P resuspension and settling capacities by 16％and 46％,respectively.(3)The sediment-water interface(SWI)plays a critical role in P transfer within the river,as resuspension accounts for 16％of TP imports,and settling accounts for 47％of TP exports.Given the large P retention capacity of lowland rural rivers,drainage ditches and ponds with macrophytes are promis-ing approaches to enhance P retention capacity.Our study provides valuable insights for local environmental departments,allowing a comprehensive understanding of P dynamics in lowland rural rivers.This enable the evaluation of the efficacy of sediment dredging in P control and the implementation of corresponding P control measures.

    200-216页
    查看更多>>摘要：Microplastics(MPs)are ubiquitous in the environment,continuously undergo aging pro-cesses and release toxic chemical substances.Understanding the environmental behaviors of MPs is critical to accurately evaluate their long-term ecological risk.Generalized two-dimensional correlation spectroscopy(2D-COS)is a powerful tool for MPs studies,which can dig more comprehensive information hiding in the conventional one-dimensional spectra,such as infrared(IR)and Raman spectra.The recent applications of 2D-COS in analyzing the behaviors and fates of MPs in the environment,including their aging processes,and inter-actions with natural organic matter(NOM)or other chemical substances,were summarized systematically.The main requirements and limitations of current approaches for exploring these processes are discussed,and the corresponding strategies to address these limita-tions and drawbacks are proposed as well.Finally,new trends of 2D-COS are prospected for analyzing the properties and behaviors of MPs in both natural and artificial environmental processes.

    查看更多>>摘要：Dissolved black carbon(DBC)plays a crucial role in the migration and bioavailability of iron in water.However,the properties of DBC releasing under diverse pyrolysis condi-tions and dissolving processes have not been systematically studied.Here,the composi-tions of DBC released from biochar through redox processes dominated by bacteria and light were thoroughly studied.It was found that the DBC released from straw biochar possess more oxygen-containing functional groups and aromatic substances.The content of phenolic and carboxylic groups in DBC was increased under influence of microorgan-isms and light,respectively.The concentration of phenolic hydroxyl groups increased from 10.0～57.5 mmol/gC to 6.6～65.2 mmol/gC,and the concentration of carboxyl groups in-creased from 49.7～97.5 mmol/gC to 62.1～113.3 mmol/gC.Then the impacts of DBC on pyrite dissolution and microalgae growth were also investigated.The complexing Fe3+was proved to play a predominant role in the dissolution of ferrous mineral in DBC solution.Due to complexing between iron ion and DBC,the amount of dissolved Fe in aquatic water may rise as a result of elevated number of aromatic components with oxygen containing groups and low molecular weight generated under light conditions.Fe-DBC complexations in solu-tion significantly promoted microalga growth,which might be attributed to the stimulating effect of dissolved Fe on the chlorophyll synthesis.The results of study will deepen our understanding of the behavior and ultimate destiny of DBC released into an iron-rich envi-ronment under redox conditions.

    查看更多>>摘要：Enhancing soil organic matter characteristics,ameliorating physical structure,mitigating heavy metal toxicity,and hastening mineral weathering processes are crucial approaches to accomplish the transition of tailings substrate to a soil-like substrate.The incorporation of biomass co-pyrolysis and plant colonization has been established to be a significant factor in soil substrate formation and soil pollutant remediation.Despite this,there is presently an absence of research efforts aimed at synergistically utilizing these two technologies to expedite the process of mining tailings soil substrate formation.The current study aimed to investigate the underlying mechanism of geochemical changes and rapid mineral weather-ing during the process of transforming tailings substrate into a soil-like substrate,under the combined effects of biomass co-smoldering pyrolysis and plant colonization.The findings of this study suggest that the incorporation of smoldering pyrolysis and plant coloniza-tion induces a high-temperature effect and biological effects,which enhance the physical and chemical properties of tailings,while simultaneously accelerating the rate of mineral weathering.Notable improvements include the amelioration of extreme pH levels,nutrient enrichment,the formation of aggregates,and an increase in enzyme activity,all of which collectively demonstrate the successful attainment of tailings substrate reconstruction.Evi-dence of the accelerated weathering was verified by phase and surface morphology analysis using X-ray diffraction and scanning electron microscopy.Discovered corrosion and frag-mentation on the surface of minerals.The weathering resulted in corrosion and fragmenta-tion of the surface of the treated mineral.This study confirms that co-smoldering pyrolysis of biomass,combined with plant colonization,can effectively promote the transformation of tailings into soil-like substrates.This method has can effectively address the key chal-lenges that have previously hindered sustainable development of the mining industry and provides a novel approach for ecological restoration of tailings deposits.

    Jia WangJiechen YinDanhong PengXiaoqian Zhang...
    244-258页
    查看更多>>摘要：4-Nitrophenol(4-NP),as a toxic and refractory pollutant,has generated significant concern due to its adverse effects.However,the potential toxic effects and mechanism remained un-clear.In this study,the reproduction,development,locomotion and reactive oxygen species(ROS)production of Caenorhabditis elegans were investigated to evaluate the 4-NP toxicity.We used metabolomics to assess the potential damage mechanisms.The role of metabo-lites in mediating the relationship between 4-NP and phenotypes was examined by cor-relation and mediation analysis.4-NP(8 ng/L and 8 pg/L)caused significant reduction of brood size,ovulation rate,total germ cells numbers,head thrashes and body bends,and an increase in ROS.However,the oosperm numbers in uterus,body length and body width were decreased in 8 pg/L.Moreover,36 differential metabolites were enriched in the sig-nificant metabolic pathways,including lysine biosynthesis,β-alanine metabolism,trypto-phan metabolism,pentose phosphate pathway,pentose and glucuronate interconversions,amino sugar and nucleotide sugar metabolism,starch and sucrose metabolism,galactose metabolism,propanoate metabolism,glycerolipid metabolism,and estrogen signaling path-way.The mechanism of 4-NP toxicity was that oxidative stress caused by the perturbation of amino acid,which had effects on energy metabolism through disturbing carbohydrate and lipid metabolism,and finally affected the estrogen signaling pathway to exert toxic effects.Moreover,correlation and mediation analysis showed glycerol-3P,glucosamine-6P,glucosamine-1P,UDP-galactose,L-aspartic acid,and uracil were potential markers for the re-production and glucose-1,6P2 for developmental toxicity.The results provided insight into the pathways involved in the toxic effects caused by 4-NP and developed potential biomark-ers to evaluate 4-NP toxicity.
