    ABSTRACT: To deeply understand the effects of hydrodynamics on microbial community, the roles of niche-based and neutral processes must be considered in a mathematical model. To this end, a two-dimensional model combining mechanisms of immigration, dispersal, and niche differentiation was firstly established to describe the effects of hydrodynamics on bacterial communities within fluvial biofilms. Deterministic factors of the model were identified via the calculation of Spearman's rank correlation coefficients between parameters of hydrodynamics and bacterial community. It was found that turbulent kinetic energy and turbulent intensity were considered as a set of reasonable predictors of community composition, whereas flow velocity and turbulent intensity can be combined together to predict biofilm bacterial biomass. According to the modelling result, bacterial community could get its favorable assembly condition with flow velocity ranging from 0.041 to 0.061 m/s. However, the driving force for biofilm community assembly changed with the local hydrodynamics. Individuals reproduction within biofilm was the main driving force with flow velocity less than 0.05 m/s, while cells migration played a much more important role with velocity larger than 0.05 m/s. The developed model could be considered as a useful tool for improving the technologies of water environment protection and remediation.

    ABSTRACT: To safely and effectively apply artemisinin sustained-release granules to control and prevent algal water-blooms, the effects of artemisinin and its sustained-release granules on freshwater alga (Scenedesmus obliquus (S. obliquus) and Microcystis aeruginosa (M. aeruginosa)), as well as the production and release of microcystins (MCs) were studied. The results showed that artemisinin sustained-release granules inhibited the growth of M. aeruginosa (above 95 % IR) and S. obliquus (about 90 % IR), with M. aeruginosa more sensitive. The artemisinin sustained-release granules had a longer inhibition effect on growth of pure algae and algal coexistence than direct artemisinin dosing. The artemisinin sustained-release granules could decrease the production and release of algal toxins due to the continued stress of artemisinin released from artemisinin sustained-release granules. There was no increase in the total amount of MC-LR in the algal cell culture medium.

    ABSTRACT: Stability of engineered nanoparticles in aquatic environment is an essential parameter to evaluate their fate, bioavailability, and potential toxic effects toward living organisms. As CuO NPs enter the wastewater systems, they will encounter extracellular polymeric substances (EPS) from microbial community before directly interacting with bacterial cells. EPS may play an important role in affecting the stability and the toxicity of CuO NPs in aquatic environment. In this study, the influences of flocculent sludge-derived EPS, as well as model protein (BSA) and natural polysaccharides (alginate) on the dissolution kinetics and colloidal stability of CuO NPs were investigated. Results showed that the presence of NOMs strongly suppressed CuO NPs aggregation, confirmed by DLS, zeta potentials, and TEM analysis. The enhanced stability of CuO NPs in the presence of EPS and alginate were attributed to the electrostatic combined with steric repulsion, while the steric-hindrance effect may be the predominant mechanism retarding nano-CuO aggregation for BSA. Higher degrees of copper release were achieved with the increasing concentrations of NOMs. EPS are more effective than alginate and BSA in releasing copper, probably due to the abundant functional groups and the excellent metal-binding capacity. The ratio of free-Cu 2? /total dissolved Cu significantly decreased in the presence of EPS, indicating that EPS may affect the speciation and Cu bioavailability in aqueous environment. These results may be important for assessing the fate and transport behaviors of CuO NPs in the environment as well as for setting up usage regulation and treatment strategy.

    ABSTRACT: The precise evaluation of arsenic (As) and mercury (Hg) bioavailability in sediment is crucial to controlling As and Hg contamination, but traditional ex situ measurements hamper comprehensive analysis of labile As and Hg in sediment. In this study, we characterized in situ labile As and Hg in sediment of Lake Hongze using the zirconium (Zr) oxide diffusive gradients in thin films (DGT) technique and 3-mercaptopropyl functionalized silica gel DGT, respectively. The concentrations of DGT-labile As and Hg in the sediment profiles were found to exhibit considerable variation, ranging from 0.15 to 4.15μgL(-1) for As and from 0.04 to 1.35μgL(-1) for Hg. As and Hg flux values, calculated based on the concentration gradients measured from the DGT profiles for both the overlying water and sediment close to the sediment-water interface, were used to determine the contamination status of As and Hg. Flux values of As and Hg were between -0.066 and 0.067ngcm(-2)d(-1) and between -0.0187 and 0.0181ngcm(-2)d(-1), respectively. The GNU's Not Unix R (GNU R) programming language was used to identify outliers of As and Hg at various depths at the sampling sites. The results indicate that the sites with the most outliers were all located in the regions that were seriously affected by contaminants from the Huai River. The DGT-labile As and Hg concentrations in the 0-30mm layer were found to be significantly correlated with concentrations of labile As and Hg, total dissolved As and Hg, and total As and Hg in the overlying water, as indicated by ex situ measurements. Results show that DGT is a reliable and high-resolution technique that can be used for in situ monitoring of the labile fractions of As and Hg in sediment in fresh water bodies.

    ABSTRACT: Eutrophication and cyanobacterial blooms have become the most severe problems affecting the water body function of Taihu Lake. In order to understand the distribution of phytoplankton and their co-relationship with environmental factors, the phytoplankton and environmental factors were observed in different parts of Taihu Lake in the summer (July) and winter (December) of 2013. By using diversity indexes and a redundancy analysis (RDA), this study revealed that Cyanophyta, Chlorophyta and Bacillariophyta were the majority, and the main impact factors were total phosphorus (TP), total nitrogen (TN), phosphate (PO43–-P), ammonia nitrogen (NH4+-N) and dissolved oxygen (DO). During the summer, the Microcystis of Cyanophyta were the most prevalent. However, during the winter, the prevalence of all of the species and the abundance of algae decreased greatly and Bacillariophyta became dominant. The northwestern, algae-type portion of the lake had the highest abundance of Microcystis, which suffered serious eutrophication. In contrast, the eastern, grass-type portion of the lake had the lowest abundance of algae but the highest content of Bacillariophyta, indicating superior water quality. Based on the above analysis, suggestions were given to prevent and control algal blooms. In addition to decreasing the input of exogenous nutrients, sediment dredging may be performed in the northwestern portion during the winter to eliminate the blue green algae in the resting stage to some extent. Meanwhile, macrophytes should also be reconstructed in northern bays to restrain the rampant growth of phytoplankton.

    ABSTRACT: Hydrogen evolution by photocatalytic water splitting has attracted extensive attention in recent years. Here we report a composite photocatalyst, in which graphene and Pt particles act as cocatalysts to modify CdS nanowires. This composite photocatalyst was prepared by a solvothermal method followed by a photoreduction process. The obtained samples were characterized by X-ray powder diffraction, UV-vis diffuse reflectance spectroscopy, scanning and transmission electron microscopy, X-ray photoelectron spectroscopy, photoluminescence and Brunauer-Emmett-Teller specific surface area analysis. The graphene and Pt comodified CdS nanowires gain a high hydrogen evolution rate of 3984 μmol h(-1) g(-1), which is almost 4 times higher than that of bare CdS nanowires and also higher than the sum of graphene-CdS and Pt-CdS nanowires. The obtained sample also exhibits a good stability. The encouraging results presented here can be attributed to the incorporation of graphene and Pt which show a synergetic effect for hydrogen evolution. This work paves a way to the potential application of CdS nanowires in energy conversion.

    ABSTRACT: Surface sediments were collected from the Yangtze River Estuary (YRE) in May 2012, August 2012, November 2012 and February 2013 to analyse the seasonal and spatial distributions of acid-volatile sulphide (AVS), simultaneously extracted metals (SEM) and the sediment toxicity. An optimised method was used for the AVS and SEM analysis and the results showed that the seasonal variations of AVS were positively correlated with changes in water temperature and the position of higher AVS was relatively fixed. The average of SEM was gradually increased from May 2012 to February 2013 and there were abnormally high values of SEMCu and SEMNi in the YRE. Concentrations of the five SEM components were in the following order: Cd < Pb < Cu ≈ Ni < Zn. The correlations among the concentrations of the five metals suggested that these metals in the sediments of the YRE did not have stable anthropogenic and/or natural origin. The mean values of AVS and SEM in the YRE were closer to those in the Huanghe Estuary and were lower than those in the Pearl River Estuary. The results of two sediment toxicity assessments showed that the sediments of most areas in the YRE had potential sediment toxicities, especially the Ni and Cu contamination.

    ABSTRACT: To understand the relationship between elevation and bacterial communities in wastewater treatment plants (WWTPs), bacterial communities were investigated by 454-pyrosequencing in twenty-one municipal WWTPs located at 9 to 3660 meters above sea level (masl) across China. A threshold of elevation associated with bacterial community richness and evenness was observed at approximately 1200 masl. At lower elevations, both richness and evenness were not significantly associated with elevation. At higher elevations, significant decline trends with elevation were observed in community richness and evenness. The declining evenness trend at the phylum level was reflected by distinct trends of individual bacterial phyla in relative abundance. Betaproteobacteria, Bacteroidetes, and Firmicutes displayed significantly increasing trends, while most others declined. Spearman correlation analysis indicated that the community richness and evenness at high elevations were more correlated with elevation than any other single environmental variable. Redundancy analysis indicated that the contribution of elevation to community composition variances increased from 3% at lower elevations to 11% at higher elevations, whereas the community composition variance at higher elevations remained much more explained by operational variables (39.2%) than elevation. The influent total phosphorus concentration, food/microorganism ratio, and treatment process were the three shared dominant contributors to the community composition variance across the whole elevational gradient, followed by effluent ammonia nitrogen and temperature at higher elevations.

    ABSTRACT: Extracellular polymeric substances (EPS) are a major component of biofilms that act as a gel-like matrix, binding the cells together to form their three-dimensional structure. The effects of ceria nanoparticles (CeO2 NPs) on the production and physicochemical characteristics of EPS in biofilms in a sequencing batch biofilm reactor were investigated. Total EPS production, including loosely bound EPS (LB-EPS) and tightly bound EPS (TB-EPS), increased by 35.41% compared to in control tests without CeO2 NPs. Protein production increased by 47.02% (LB-EPS) and 58.83% (TB-EPS) after 50mg/L CeO2 NP exposure. Three-dimensional excitation-emission fluorescence spectra revealed that tyrosine (LB-EPS) and aromatic (TB-EPS) protein-like substances formed after CeO2 NP exposure. Fourier transform infrared spectroscopy results indicated the susceptibility of -OH and -NH2 in EPS hydroxyl and amine groups to CeO2 NPs. Exposure to 50mg/L CeO2 NPs reduced the flocculating capacity of LB-EPS (51.78%) and TB-EPS (17.14%), consistent with the decreased zeta potential. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: In this paper, graphene (GR) and titania co-modified flower-like Bi2O2CO3 multi-heterojunction composite photocatalysts were prepared by a simple and feasible two step hydrothermal process. The prepared samples were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectrometry (DRS), photoluminescence (PL), N2 adsorption-desorption isotherm, and photo-induced current. The photocatalytic activity was investigated by the degradation of MO under UV light irradiation. The as prepared multi-heterojunction GR/Bi2O2CO3/TiO2 composites exhibited much higher photocatalytic activity than pure Bi2O2CO3, TiO2 and GR-Bi2O2CO3. The higher performance of GR/Bi2O2CO3/TiO2 can be ascribed to the formation of multi-heterojunctions, which promote the effective separation of photo-induced electron-hole pairs. Moreover, the higher photocatalytic activity can also be ascribed to the high surface area of GR and TiO2, which offers more active sites for the photodegradation reaction. Furthermore, the photocatalytic activity of GR/Bi2O2CO3/TiO2 remained without striking decrease after five cycles, which indicates the excellent stability of GR/Bi2O2CO3/TiO2 composites. This work would pave a way to the design of high efficient multi-heterojunction photocatalysts.

    ABSTRACT: A BiOBr/Co-Ni-NO3 layered double hydroxide (LDH) nanocomposite was prepared by an in situ growth method via a facile anion-exchange precipitation process. The resulting BiOBr/Co-Ni-NO3 LDH nanocomposite was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible diffuse reflectance spectroscopy (UV-DRS), and Brunauer-Emmett-Teller (BET) surface areas. Results showed that the BiOBr nanosheets dispersed well on the surface of the LDHs in a vertical manner, like arrays. Moreover, compared to pure BiOBr nanosheets, Co-Ni-NO3 LDHs and Co-Ni-Br LDHs, the BiOBr/Co-Ni-NO3 LDH nanocomposite showed much higher adsorption and photocatalytic properties for organic dyes (methyl orange (MO), rhodamine B (RhB)) and phenol under UV-light irradiation. Furthermore, the mechanism of photocatalytic degradation of dyes under UV-light irradiation was investigated in detail. This work paves a way to design new types of LDH-based 2D-2D composite photocatalysts with high adsorption and photocatalytic activity. This journal is

    ABSTRACT: In this work, a series of novel flower-like Bi2O2CO3/CdS heterojunctions were prepared by a simple and feasible two-step process. The phase structures of as-prepared samples were examined by X-ray diffraction (XRD). Scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) were used to confirm the flower-like heterostructures of the Bi2O2CO3/CdS composites. The Brunauer-Emmett-Teller (BET) specific surface area (SBET) of samples were analyzed by N2 adsorption-desorption isotherms. UV-vis diffuse reflectance spectrometry (DRS) revealed that Bi2O2CO3/CdS heterojunctions exhibited better light absorptive properties than pure Bi2O2CO3. The photocatalytic activity was investigated by the degradation of MB under visible light irradiation. The results showed that the as-prepared Bi2O2CO3/CdS heterojunctions exhibited much higher activity than pure Bi2O2CO3. The photoluminescence (PL) spectra and photocurrent studies indicated that the recombination of photogenerated electron-hole pairs was decreased effectively due to the formation of heterojunctions between flower-like Bi2O2CO3 and CdS nanoparticles. Trapping experiments indicated that ˙O(2-) radicals were the main reactive species for MB degradation in the present photocatalytic system. Furthermore, the cycling experiments revealed the good stability of Bi2O2CO3-CdS composites.

    ABSTRACT: This study aimed to investigate the performance of chitosan-modified nano-sized montmorillonite (CTS/NMMT) during the flocculation of Microcystis aeruginosa (MA). The release of intracellular microcystins (MCs) caused by the damage of intact MA cells during the flocculation and floc storage processes was also comprehensively evaluated through scanning electron microscopy (SEM) and measurement of K(+) and Mg(2+) release. With the application of the Box-Behnken experimental design combined with response surface methodology, the quadratic statistical model was established to predict and optimize the interactive effects of content of CTS/NMMT, weight ratio of NMMT to CTS, and agitation time on the removal efficiency of MA cells. A maximum removal of 94.7 % MA cells was observed with content of CTS/NMMT 300-320 mg L(-1), weight ratio of NMMT to CTS 14-16, and agitation time 16-50 min. During the flocculation process, CTS/NMMT aggregated MA cells as flocs and served as a protection shield for cells. The extracellular and intracellular microcystin-leucine-arginine (MC-LR) decreased remarkably and the yield of intracellular MC-LR showed a decreasing trend during the flocculation. The cell integrity was slightly damaged by the mechanical actions rather than by the flocculant. During the floc storage process, cell lysis and membrane damage were remarkably aggravated. The noticeable increase of K(+) and Mg(2+) release indicated that CTS/NMMT damaged the integrity of most MA cells in the flocs and liberated the intracellular MC-LR. Meanwhile, NMMT and CTS polymers assisted the adsorptive removal of extracellular MC-LR released to water. The flocs should be timely treated within 12 h to prevent the leakage of MCs.

    ABSTRACT: Antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are emerging contaminants of environmental concern. Heterotrophic bacteria in activated sludge have an important role in wastewater treatment plants (WWTPs). However, the fate of cultivable heterotrophic ARB and ARGs in WWPTs process remains unclear. In the present study, we investigated the antibiotic-resistant phenotypes of cultivable heterotrophic bacteria from influent and effluent water of three WWTPs and analysed thirteen ARGs in ARB and in activated sludge from anoxic, anaerobic and aerobic compartments. From each influent or effluent sample of the three plants, 200 isolates were randomly tested for susceptibility to 12 antibiotics. In these samples, between 5% and 64% isolates showed resistance to >9 antibiotics and the proportion of >9-drug-resistant bacteria was lower in isolates from effluent than from influent. Eighteen genera were identified in 188 isolates from influent (n=94) and effluent (n=94) of one WWTP. Six genera (Aeromonas, Bacillus, Lysinibacillus, Microbacterium, Providencia, and Staphylococcus) were detected in both influent and effluent samples. Gram-negative and -positive isolates dominated in influent and effluent, respectively. The 13 tetracycline-, sulphonamide-, streptomycin- and β-lactam-resistance genes were detected at a higher frequency in ARB from influent than from effluent, except for sulA and CTX-M, while in general, the abundances of ARGs in activated sludge from two of the three plants were higher in aerobic compartments than in anoxic ones, indicating abundant ARGs exit in the excess sledges and/or in uncultivable bacteria. These findings may be useful for elucidating the effect of WWTP on ARB and ARGs. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: Abstract The effect of the water matrix components of a secondary effluent of a urban wastewater treatment plant on the photocatalytic activity of Ag/AgCl @ chiral TiO2 nanofibers and the undergoing reaction mechanisms were investigated. These effects were evaluated through the water components-induced changes on the net rate of hydroxyl radical (OH) generation and modeled using a relative rate technique. Dissolved organic matter DOM (k = −2.8 × 108 M−1 s−1) scavenged reactive oxygen species, Cl− (k = −5.3 × 108 M−1 s−1) accelerated the transformation from Ag to AgCl (which is not photocatalytically active under visible-light irradiation), while Ca2+ at concentrations higher than 50 mM (k = −1.3 × 109 M−1 s−1) induced aggregation of Ag/AgCl and thus all of them revealed inhibitory effects. In contrast, NO3− (k = 6.9 × 108 M−1 s−1) and CO32− (k = 3.7 × 108 M−1 s−1) improved the photocatalytic activity of Ag/AgCl slightly by improving the rate of HO generation. Other ubiquitous secondary effluent components including SO42− (k = 3.9 × 105 M−1 s−1), NH3+ (k = 3.5 × 105 M−1 s−1) and Na+ (k = 2.6 × 104 M−1 s−1) had negligible effects. 90% of 17-α-ethynylestradiol (EE2) spiked in the secondary effluent was removed within 12 min, while the structure and size of Ag/AgCl @ chiral TiO2 nanofibers remained stable. This work may be helpful not only to uncover the photocatalytic mechanism of Ag/AgCl based photocatalyst but also to elucidate the transformation and transportation of Ag and AgCl in natural water.

    ABSTRACT: Sedimentary biogenic silica (BSi) is an important parameter for understanding biogeochemical processes in estuarine ecosystems. In this study, a two-step mild acid–mild alkaline extraction procedure was used to leach BSi and its early diagenetic products from the sediments of the Yangtze Estuary. A Si/Al correction of the mild alkaline leachable silica (Si-Alk) was applied to estimate the contents of BSi in the sediments. The BSi contents varied from 18.90 to 120.10 μmol Si/g in the sediments, whereas mild acid leachable silica (Si-HCl) and Si-Alk levels ranged from 17.43 to 73.56 and from 19.56 to 185.63 μmol Si/g, respectively. Furthermore, the degrees of diagenetic alteration of biogenic and reactive silica were also calculated and discussed. The diagenetic alteration ratios of biogenic and reactive silica increased seaward during May, August and November 2012, whereas an opposite trend was observed in March 2013. The diagenetic alteration of the biogenic and reactive silica was mainly controlled by the redox conditions in benthic sediments. Additionally, the deposition of fresh diatoms and authigenic products could temporarily affect the distribution of silica pools in the sediments and ultimately affect the diagenetic alteration ratios of biogenic and reactive silica. Detailed investigations are still necessary to understand the early diagenetic processes of biogenic and reactive silica in this warm temperate area.
