关键词： Riverine nitrogen exports;Legacy nitrogen;Net anthropogenic nitrogen inputs;Landscape pattern;Subtropics;Sources catchment

摘要： Changes in the landscape pattern can disturb legacy nitrogen (N) release by influencing hydrological and biogeochemical processes; thus, understanding the effects of landscape patterns on riverine N exports from legacy sources is critical for preparing water quality improvement strategies. In this study, an empirical statistical model that incorporates the net anthropogenic nitrogen input (NANI), runoff coefficient, and residential land area percentage was used to quantify the contribution of legacy sources to annual riverine ammonium nitrogen (NH4+–N), nitrate nitrogen (NO3−–N), and total nitrogen (TN) exports in eight adjacent agricultural catchments in subtropical southern China. The results indicated that annual riverine NH4+–N, NO3−–N, and TN exports from legacy sources ranged from 0.36–1.03, 3.09–4.89, and 3.94–6.79kgha−1 year−1, respectively, during the 2012–2017 period. Redundancy analysis (RDA) was used to analyze the interactions between legacy N release and landscape metrics at both the landscape and class levels. The RDA results suggested that higher dispersion, lower shape complexity, and greater heterogeneity in landscape patches can enhance the release of legacy N at the landscape level. In agricultural and residential areas, higher release of legacy N was associated with patches that are unfragmented and have a low shape complexity, whereas in woodland areas, the opposite was true. These analyses provide scientific support for preparing legacy N control strategies from the perspective of landscape ecology. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG part of Springer Nature.

关键词： Mining and manufacturing;Rock weathering;Fertilizer and pesticide use;Principal component analysis;Mixed metal pollution;Surface water pollution

摘要： This study collected past sampling data on total concentrations of 12 heavy metals (Cd, Pb, Cr, Hg, Zn, Cu, Ni, Al, Fe, Mn, As, and Co) in surface water bodies, i.e., 168 rivers and 71 lakes, from 1972 to 2017. The intent was to investigate the levels and sources of heavy metal pollution across five decades and five continents. Mean heavy metal concentrations in global river and lake water, and the number of heavy metals with concentrations greater than the published threshold limits as per the standards of both the World Health Organization (WHO) and the United States Environmental Protection Agency (USEPA) were generally lower in the 1970s and 1980s than in the 1990s, 2000s, and 2010s. Over time, heavy metal pollution in surface water has changed from single metal pollution to mixed metal pollution. Heavy metal concentrations in water, and the number of heavy metals with concentrations above the threshold limits for both WHO and USEPA standards were lower in the developed countries of Europe and North America, and higher in the developing countries of Africa, Asia, and South America. Over time, the main sources of metal pollution have changed from mining and manufacturing to rock weathering and waste discharge. The main metal sources differed across the five continents, with fertilizer and pesticide use, along with rock weathering, being dominant in Africa. Mining and manufacturing, along with rock weathering, were dominant in Asia and Europe. Mining and manufacturing, along with fertilizer and pesticide use, were dominant sources in North America, while four sources (mining and manufacturing, fertilizer and pesticide use, rock weathering, and waste discharge) were responsible for the majority of heavy metal pollution in the river and lake water bodies of South America. Additionally, implementing rigorous standards on metal emissions and recycling metals from wastewater are effective for controlling heavy metal source pollution. (C) 2020 The Authors.

摘要： Fast and effective removal of elemental mercury in a wide temperature range is critical for the smelting industry. In this work, a recyclable magnetic iron sulfide/selenide sorbent is developed to capture and recover Hg0 from smelting flue gas. Benefiting from Se doping, the Hg0 capture performance of prepared FeSxSey is significantly enhanced compared with traditional iron sulfide, especially at high temperatures. Considering the recyclability and working temperature, FeS1.32Se0.11 exhibits the best Hg0 capture performance. The average capture rate of FeS1.32Se0.11 is 3.661 μg/g/min at 80 °C and its saturation adsorption capacity is 20.216 mg/g. The flue gas compositions have almost no effect on Hg0 capture. X-ray photoelectron spectroscopy and mercury thermal programmed desorption suggest that the stable active Se-Sn 2- adsorption site can combine with Hg0 to form HgSe, consequently improving Hg0 capture performance at high temperatures. After Hg0 capture, the spent FeSxSey can be collected by magnetic separation and regenerated through selective extraction, which facilitates harmless treatment and resource reuse of mercury. With the advantages of excellent Hg0 capture performance, wide operating temperature range, and remarkable recycling property, FeSxSey microparticles may be a promising sorbent for Hg0 capture in industrial applications, while opening a new avenue to realize the resource utilization toward toxic elements. © 2019 American Chemical Society.

关键词： Marsh;River;Lake;Reservoir;Forest land;Regional temperature

摘要： Based on the wetland areas recorded in the First National Inventory of Wetland Resources (FNIWR; 1999-2001) and the Second National Inventory of Wetland Resources (SNIWR; 2009-2011), as well as regional environmental parameters including meteorological conditions and land-use structure, the driving forces of changes in China's wetland area from the FNIWR to the SNIWR were investigated. The total area of China's wetlands larger than 1 km(2) decreased from 384.8 x 10(3) km(2) in the FNIWR to 350.8 x 10(3) km(2) in the SNIWR. Natural wetland areas, including marshes, rivers, lakes, and coastal wetlands, decreased by 33.8 x 10(3) km(2) over the study period, accounting for 99.4% of the decrease in the wetland area. Regions with decreased marsh and reservoir wetland areas were located mainly in Central and Eastern China, and those with increased river and lake wetland areas were located in Western China. There were no significant regression coefficients between the percentages of change in marsh and lake wetland areas and environmental parameters. However, changes in river wetland areas were positively regressed with changes in forest areas, mean annual temperature, and extreme minimum temperature, and changes in reservoir wetland areas were positively regressed with changes in city construction areas and mean annual temperature. Therefore, it seems that increased forest area and regional temperature alleviated the degradation of river wetland areas, while increased city construction areas and regional temperature alleviated the degradation of reservoir areas.

摘要： The presence of excessive pollutants in soil and water caused by the fast development of industry has been a challenge for the innovation of environmental remediation technologies. Nano-sized iron sulfide (FeS) particles have aroused researchers’ attention for environmental remediation over the decade owing to their high reactivity and large specific surface area. The aim of this paper is to provide a comprehensive review on the evolution of FeS nanoparticles for environmental decontamination. The synthesis for bare nano-sized FeS particles via physicochemical and biological methods, the modification for nano-sized FeS particles by coating stabilizers and loading supporting materials are described in this review. What's more, the applications of nano-scale FeS in soil and water remediation are also discussed, including the removal of halogenated hydrocarbon, radionuclide, heavy metals, and metalloid. Meanwhile, the interaction mechanisms, namely adsorption and redox reaction between contaminants and nano-sized FeS and the effect of remediation conditions have been summarized in this review. Moreover, some future research needs are also stated such as researching the fate of FeS nanoparticle after injecting into soil and water, enhancing the mobility of nano-sized FeS in soil and water, and measuring the toxicity to the organisms. © 2019 Elsevier B.V.

关键词： Co-composting;Heavy metals;Phanerochaete chrysosporium;Redundancy analysis;Sediment

摘要： The effects of Phanerochaete chrysosporium on the bioavailability of multiple heavy metals (Pb, Cd, Cu, and Zn) in river sediments were investigated by co-composting with the agricultural waste. The results showed that the Phanerochaete chrysosporium inoculation can greatly enhance the passivation on Cu, Pb and Cd during 60 days co-composting. The effects in the three metals followed the order: Cu>Cd>Pb. There were no differences for Zn whether inoculation with P. chrysosporium or not. Redundancy analysis (RDA) implied that more than 4/5 of the variation of all fractions data for all heavy metals was explained by all significant canonical axes. P. chrysosporium can change the significant parameters for each metal and enhance the explanatory power of RDA model. The inoculation can strengthen the effect of OM (organic matter) on the bioavailability of heavy metals, but weaken the contribution of pH.

关键词： Capture;Core-shell structure;Gaseous As2O3;Iron oxide;Magnetic composites

摘要： Gaseous arsenic capture from flue gas is of great concern due to the high toxicity of arsenic. In this study, a new type of sorbent, magnetic Fe3O4@C@Fe2O3 microparticles with a core-shell structure, was designed by taking advantages of the easy separation property of magnetic sorbents and the excellent adsorption property of Fe2O3 for the capture of arsenic. The Fe3O4@C@Fe2O3 material exhibits a three-layer structure with high specific surface area (27.242 m2 g−1), large pore volume (0.181 cm3 g−1) and excellent magnetic properties (74.1 emu g−1). The synthesized Fe3O4@C@Fe2O3 sorbent demonstrates better arsenic capture performance than Fe3O4, Fe3O4@C or commercial Fe2O3 materials. The capture rate of Fe3O4@C@Fe2O3 for gaseous As2O3 could reach 1.94 mg g−1 min−1 in optimal conditions, and its capacity is 36.22 mg g−1 with a breakthrough threshold of 50%. The performance tests indicate that gaseous As2O3 could be efficiently captured from simulated flue gas and that the presence of SO2 and O2 plays a crucial role in As2O3 capture. The capture mechanism indicates that the conversion of Fe3+/Fe2+ during the oxidation of SO2 by O2 can accelerate the formation of highly active chemisorbed oxygen, and then the adsorbed As2O3 can bond with chemisorbed oxygen to from stable Fe(III)-As(V) compound. After magnetic separation, the spent sorbent can be regenerated through alkali desorption, which facilitates the centralized control of arsenic and the recycling of sorbent. Therefore, the Fe3O4@C@Fe2O3 composite is a promising sorbent for gaseous As2O3 capture from SO2-containing flue gas due to its excellent separation and regeneration properties. © 2019

摘要： An integrated solar water splitting tandem cell without external bias was designed using a FeOOH modified TiO 2 /BiVO 4 photoanode as a photoanode and p-Cu 2 O as a photocathode in this study. An apparent photocurrent (0.37 mA/cm 2 at operating voltage of +0.36 V RHE ) for the tandem cell without applied bias was measured, which is corresponding to a photoconversion efficiency of 0.46%. Besides, the photocurrent of FeOOH modified TiO 2 /BiVO 4 –Cu 2 O is much higher than the operating point given by pure BiVO 4 and Cu 2 O photocathode (∼0.07 mA/cm 2 at +0.42 V RHE ). Then we established a FeOOH modified TiO 2 /BiVO 4 –Cu 2 O two-electrode system and measured the current density-voltage curves under AM 1.5G illumination. The unassisted photocurrent density is 0.12 mA/cm −2 and the corresponding amounts of hydrogen and oxygen evolved by the tandem PEC cell without bias are 2.36 μmol/cm 2 and 1.09 μmol/cm 2 after testing for 2.5 h. The photoelectrochemical (PEC) properties of the FeOOH modified TiO 2 /BiVO 4 photoanode were further studied to demonstrate the electrons transport process of solar water splitting. This aspect provides a fundamental challenge to establish an unbiased and stabilized photoelectrochemical (PEC) solar water splitting tandem cell with higher solar-to-hydrogen efficiency. © 2018 Hydrogen Energy Publications LLC

摘要： Tungsten oxide (WO3) nanoplate films with a relatively rough surface were successfully fabricated via a simple hydrothermal method, followed by the hybrid microwave annealing (HMA) treatment only a few minutes for the first time. The microscopic morphology and phase were characterized by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM), Raman spectrum and X-ray diffraction (XRD). Photoelectrochemical measurements demonstrated that the obtained WO3 film of microwave processing for 11 min exhibited the photocurrent density of 1.60 mA/cm2 at 1.2 V (vs. Ag/AgCl) and the IPCE value of 55% at 355 nm under an applied voltage of 1.0 V (vs. Ag/AgCl), which were about 3 and 2.5 times compared with the WO3 film prepared by the conventional annealing method, respectively. Moreover, the WO3-HMA films were applied to the versatile photoanode-driven photoelectrochemical system for CO2 reduction into formic acid. The maximum formic acid generation rate and faradaic efficiency of the WO3-HMA films were 9.21 μmol h−1 cm−2 and 45.45%, respectively. This study provided a facial and rapid method to synthesize the high-performance WO3 photoanodes with better photoelectrochemical and photoelectrocatalytic activities. © 2018 Hydrogen Energy Publications LLC

关键词： Fenton pretreatment;Lignin;Ligninolytic enzymes;Rice straw

摘要： The rice straw (RS) is a kind of recalcitrant lignocellulosic material. The Fenton reaction has been widely used for the degradation of organic compounds and toxic chemicals. Therefore, applying it to pretreatment straw seems to have good potential. This study was to investigate the degradation of the pretreated RS by the mixed solid-state culture with Phanerochaete chrysosporium and Aspergillus nigert. The results showed that the degree of delignifition was 15.01% by using an optimized Fenton reagent (6 g/L of FeSO<inf>4</inf>&middot;7H<inf>2</inf>O and 15% concentration of H<inf>2</inf>O<inf>2</inf>) at a solids loading of 5% (w/v) and a moderate temperature for 15 h. The analysis of the Fenton pretreated RS by Scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) showed significant changes in physicochemical structure, favoring the subsequently susceptibility of ligninolytic enzymes. The volatile organic compounds collected from the mixed solid-state culture implied the degradation degree of the lignocellulose to some extent. In conclusion, Fenton pretreatment could effectively disrupt the recalcitrant structure of RS and accelerate its biodegradation, which has high potential application in the energy conversion and utilization of lignocellulose.<br/> &copy;2017 Elsevier B.V.

摘要： H2O, as a product of reduced reaction by H2, may affect the chemical equilibrium according to the changing of the pressure ratio of H2O/H2 in the system. Meanwhile, the performance may also be influenced by adsorption of H2O on the surface of the material. In this work, the effect of H2O is studied by reducing plate-like array WO3 films under different pressure ratio of H2O/H2. It is controlled by changing the water temperature in the washing bottle through which the Ar/H2 (80:20) gas flows. The higher water vapor pressure not only decreases the content of W5+ but also increases the content of surface hydroxyl groups in the WO3 films. Moreover, the excess water vapor improves the crystallinity. The WO3 film shows hydrophobicity with adhesive property and high contact angle hysteresis after reduction, and the wettability increases with the increase of the pressure ratio of H2O/H2. Additionally, a built-in electric field may form by dissociation of the surface hydroxyl group and absorption of O− species, which promotes the charge separation, showing better photoelectrochemical (PEC) performance. Thus, water influences the coverage of chemical species on the surface of hydrogen reduced WO3 film, which affects the wettability and PEC performance. © 2017

摘要： Bioremediation of heavy metal polluted soil using metal-resistant bacteria has received increasing attentions. In the present study, we isolated a heavy metal-resistant bacterial strain from a Cd-contaminated soil, and conducted pot experiments to evaluate the effect of bacterial inoculation in soil on soil Cd speciation, rice grain biomass and Cd accumulation. We find that the isolated bacterial strain is a Gram-negative bacterium, and named as Delftia sp. B9 based on the 16S rDNA gene sequence analysis. TEM–EDS manifests that Cd can be bioaccumulated inside cell, resulting in intracellular dissolution. The Cd contents of rice grain in the two rice cultivars (early and late rice) are all below the standard limit for Food Safety of People's Republic of China (0.2 mg/kg) after the treatment of both living and non-living cells. Non-living cells are more applicable than the use of living cells for the short time bioremediation. The average content of soil exchangeable fraction of Cd decreases whereas the residual fraction increases with bacterial inoculation. All our results suggest Delftia sp. B9 is able to the stabilization of Cd in soil and reduce Cd accumulation in rice grain, therefore, this strain is potentially suitable for the bioremediation of Cd-contaminated paddy soils. © 2018 Elsevier Inc.

摘要： Oxygen vacancy, as a kind of self-doping strategy, has been considered by numerous researchers. Several papers have been published about introducing oxygen vacancies in the semiconductors, which give a viewpoint that the concentration of oxygen vacancies may influence the performance. But few of them focus on how to control the concentration of oxygen vacancies, and how to achieve the goal without using additional equipment (such as sealed tube furnace) for too long time (20 min–4 h without considering the time for rising temperature and cooling). In this paper, oxygen vacancies were introduced into the WO3 vertically plate-like arrays films in a short time by chemical reduction. TiCl3 solutions with different concentrations were used as the reductant, and the concentration of oxygen vacancies of WO3 was proportional to the concentration of TiCl3. After importing oxygen vacancies, WO3 film photoanode showed enhanced photoelectrochemical performance, and the photocurrent of treated WO3 (0.88 mA/cm2 at 1.2 V vs. Ag/AgCl) was 1.27 times that of pristine WO3 (0.69 mA/cm2). However, the photocurrent decreased when the concentration of TiCl3 was too high. The over importation of oxygen vacancies might result in a thicker disorder layer with surface defects and more recombination centers. In such a situation, there was an unsatisfactory transfer and separation ability of photogenerated charges. This study provides new insight into controlling the concentration of oxygen vacancies via a rapid and easy approach. © 2017 Hydrogen Energy Publications LLC

关键词： Bacterial community;Biochar;Composting;Heavy metals;River sediment

摘要： Studies were performed to evaluate influence of biochar addition on physico-chemical process, heavy metals transformation and bacterial community diversity during composting of sediment with agricultural wastes. Simultaneously, the relationships between those parameters including heavy metals and bacterial community compositions were evaluated by redundancy analysis (RDA). The results show that the extraction efficiency of DTPA extractable heavy metals decreased in both piles, and reduced more in pile with biochar addition about 0.1-2.96%. Biochar addition dramatically influenced the bacterial community structure during the composting process. Moreover, the bacterial community composition was significantly correlated with C/N ratio, water soluble carbon (WSC), and organic matter (OM) (P < 0.05) in pile with biochar addition; while significantly correlated with temperature, WSC, and C/N ratio in pile which was free of biochar. This study would provide some valuable information for improving the composting for disposal of river sediment with heavy metals contamination. (C) 2017 Elsevier Ltd. All rights reserved.

摘要： This article describes the synthesis of monoclinic WO3 nanostructures with highly reactive (002) facets exposed through a facile hydrothermal method using boric acid as the guiding agent. The obtained WO3 plate films exhibit an excellent photocurrent density of 1.64mA/cm2 at 1.2V (vs. Ag/AgCl) and an IPCE value of 66.7% at 355nm at a bias of 0.8V (vs. Ag/AgCl). Furthermore, a maximum 2.8-time higher formic acid yields was obtained in a versatile photoanode-driven PEC CO2 reduction system. The pronounced enhancement in photoelectrocatalytic activity can be attributed to the reduced recombination of photogenerated electron–hole pairs, longer electron lifetime, larger photogenerated carrier density, higher reactivity for water oxidation and more effective production of active oxygen species on exposed (002) facets, which were obtained through the capping effect of boric acid. This work provides a facile and promising approach to synthesize the specific facet-exposed photocatalysts with better photoelectrochemical performance. © 2017, Springer Science+Business Media New York.

关键词： BDE-47;Degradation;Contaminated soil;Composting;PCR-DGGE;Community composition

摘要： This paper studied the degradation of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) in contaminated soil under composting and natural conditions, respectively. BDE-47 residue in agricultural waste-composting pile was determined during 45-day composting. The microbial communities were determined by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), and the relationships between the DGGE results and physico-chemical parameters were evaluated by redundancy analysis (RDA) and heatmap-clustering analysis. The results showed that the degradation rate of BDE-47 was significantly higher in agricultural waste-composting pile compared with control group, which was enhanced up to almost 15 % at the end of composting. There were different environmental factors which affected the distribution of composting bacterial and fungal communities. The bacterial community composition was more significantly affected by the addition of BDE-47 compared with other physico-chemical parameters, and BDE-47 had stronger influences on bacterial community than fungal community during the composting. Meanwhile, the most variation in distribution of fungal community was explained by pile temperature.

关键词： Sulfonamides;Excretion;Oral absorption;Residual;Pigs

摘要： Sulfonamides (SAs) are applied widely as feed additives in the farming of livestock and poultry. It can lead to the excretion of large amounts of SAs in manure and result in persistent environmental pollution. We evaluated the fate of four SAs, sulfamerazine (SM1), sulfachloropyridazine (SCP), sulfadimoxine (SDM') and sulfaquinoxaline (SQ), from oral administration to excretion in urine and feces in pigs. The four SAs were added to homemade feed to make them reach the required concentration gradient, which were 0, 50 and 100 mg/kg (low, normal and high concentrations, respectively). In different treatments, excretions of the four SAs were 35.68-86.88 %. With regard to total excretion, the order was SQ > SCP > SM1 > SDM' for all treatments. The concentration of SAs in the feed had significant effects on the amount of the four SAs excreted every day. The concentration of SAs in feces and in the urine for different treatments was 15.03-26.55 and 14.54-69.22 %, respectively. In each treatment, excretions of SCP, SDM' and SQ in feces were lower than that in urine. The four SAs remained longer in urine than in feces. Excretions in urine and feces were lower if SAs were administered orally rather than by injection.

关键词： Bi2S3 nanowire;Heterogeneous nanostructure;Hydrogen generation;Photoelectrochemical;TiO2 nanorod

摘要： In this paper, we demonstrate a novel heterogeneous nanostructure by grafting the Bi2S3 nanowires (NWs) on TiO2 nanorod arrays (NRs) and the prepared films as photoanodes show an excellent photoelectrochemical (PEC) hydrogen generation performance. The hydrogen evolution rate is 35.97 μmol cm-2 h-1 at a potential of 0.676 V vs. RHE (-0.2 V vs. Ag/AgCl) under visible light illumination. Importantly, the growth mechanism of such a heterogeneous nanostructure is put forward firstly and the intrinsic nature of Bi2S3 crystal structure is the main reason of the growth orientation. It is potential for the versatile preparation method to apply in the synthesis of other Bi2S3 based hybrid films. © 2016 Elsevier B.V..
