| 1 | Effects of water management on arsenic and cadmium speciation and accumulation in an upland rice cultivar显示文摘Pot and field experiments were conducted to investigate the effects of water regimes on the speciation and accumulation of arsenic(As) and cadmium(Cd) in Brazilian upland rice growing in soils polluted with both As and Cd. In the pot experiment constant and intermittent flooding treatments gave 3–16 times higher As concentrations in soil solution than did aerobic conditions but Cd showed the opposite trend. Compared to arsenate, there were more marked changes in the arsenite concentrations in the soil solution as water management shifted, and therefore arsenite concentrations dominated the As speciation and bioavailability in the soil. In the field experiment As concentrations in the rice grains increased from 0.14 to 0.21 mg/kg while Cd concentrations decreased from 0.21 to 0.02 mg/kg with increasing irrigation ranging from aerobic to constantly flooding conditions. Among the various water regimes the conventional irrigation treatment produced the highest rice grain yield of 6.29 tons/ha. The As speciation analysis reveals that the accumulation of dimethylarsinic acid(from 11.3% to 61.7%) made a greater contribution to the increase in total As in brown rice in the intermittent and constant flooding treatments compared to the intermittent-aerobic treatment. Thus, water management exerted opposite effects on Cd and As speciation and bioavailability in the soil and consequently on their accumulation in the upland rice. Special care is required when irrigation regime methods are employed to mitigate the accumulation of metal(loid)s in the grain of rice grown in soils polluted with both As and Cd. | Pengjie Hu Younan Ouyang Longhua Wu Libo Shen Yongming Luo Peter Christie | 2015 | Journal of Environmental Sciences2015，27，1： | 43 |
| 2 | Occurrence and assessment of veterinary antibiotics in swine manures:A case study in East China显示文摘We investigated the occurrence of 14 selected antibiotics including five therapeutic classes of tetracyclines,sulfonamides,macrolides,fluoroquinolones and chloramphenicols in manures collected from four swine farms of different sizes in eastern China.Tetracyclines(tetracycline,oxytetracycline,chlortetracycline,and doxycycline) and sulfadiazine were the most prominent contaminants in the manure samples,with maximum concentrations reaching 98.2 × 10 3,354.0 × 10 3,139.4 × 10 3,37.2× 10 3,and 7.1× 10 3 μg/kg,respectively.The occurrence of these compounds was dependent on breeding scale,animal type,and breeding season.Manure storage and vermiculture were not able to effectively deplete the heavier contaminants(tetracyclines and sulfadiazine),resulting in high levels of these chemicals remaining in manures.Therefore,the occurrence of these antibiotics in agricultural soils(0.1-205.1 μg/kg) collected from four types of agricultural land(pear orchard,tea plantation,bamboo forest,and paddy field) near the studied farms,was a reflection of manure application.However,the extremely high concentrations of antibiotics in manures were unlikely from feed consumption,but from other direct forms of medicine application. | CHEN YongShan ZHANG HaiBo LUO YongMing SONG Jing | 2012 | Chinese Science Bulletin2012，57，6： | 29 |
| 3 | Predicting As,Cd and Pb uptake by rice and vegetables using field data from China显示文摘Plant uptake factor(PUF),single-variable regression of natural log-transformed concentrations in rice grain/vegetables versus natural log-transformed concentrations in soil and multiple-variable regression with soil concentrations and pH,was derived,validated and compared based on the paired crop and soil data collected from studies regarding As,Cd and Pb contaminated croplands in China.Results showed that the median value of PUF did not present deterministic prediction.But after natural logarithm transformation,the PUF followed Gaussian distribution which could be useful in risk assessment.The single-variable regression models were significant for As,Cd and Pb uptake both by rice and vegetables;however,the standard errors of all the regressions were comparatively large.Soil pH as a variable was generally significant but it only contributed positively to model fit for Cd uptake.After model comparison and selection,the upper 95% prediction limits of the multiple regression model for Cd uptake by rice was recommended to calculate screening value of Cd for paddy soil based on the limit for Cd concentration in rice grain. | Hongzhen Zhang Yongming Luo Jing Song Haibo Zhang Jiaqi Xia Qiguo Zhao | 2011 | Journal of Environmental Sciences2011，23，1： | 12 |

| 5 | Effects of long-term fertilizer applications on peanut yield and quality and plant and soil heavy metal accumulation显示文摘The status of essential and potentially toxic trace elements in soils and crops can be affected by long-term fertilization practices. This study aimed to investigate changes in peanut (Arachis hypogaea L.) yield and kernel quality, and changes in copper (Cu), zinc (Zn), lead (Pb), and cadmium (Cd)concentrations in soil and peanut kernels after 16 years of continuous cropping with different fertilization treatments. Five fertilization treatments were applied at a red soil site in Southeast China:chemical fertilizer (F) containing nitrogen, phosphorus, and potassium, F+trace elements (FT), pig manure (M), M+effective microorganisms (MB), and MB+trace elements (MBT). Properties of soil and pig manure, heavy metal contents in soil and peanut kernels, and the compositions of amino and fatty acids in kernels were determined. Application of pig manure significantly increased peanut biomass, kernel yield, and crude protein and total amino acid contents in kernels, but led to higher amounts of Cu, Zn, and Cd in soil and higher amounts of Zn and Cd in peanut kernels compared with that of chemical fertilizer. There should be greater concern about potential kernel Cd and Zn contaminations resulting from long-term application of pig manure contaminated with potentially toxic metals as an organic fertilizer. | Xiaobing WANG Wuxing LIU Zhengao LI Ying TENG Peter CHRISTIE Yongming LUO | 2020 | Pedosphere2020，30，4： | 9 |
| 6 | Prevalent intrinsic emission from nonaromatic amino acids and poly(amino acids)显示文摘Nonaromatic amino acids are generally believed to be nonemissive, owing to their lack of apparently remarkable conjugation within individual molecules. Here we report the intrinsic visible emission of nonaromatic amino acids and poly(amino acids) in concentrated solutions and solid powders. This unique and widespread luminescent characteristic can be well rationalized by the clustering-triggered emission(CTE) mechanism, namely the clustering of nonconventional chromophores(i.e. amino, carbonyl,and hydroxyl) and subsequent electron cloud overlap with simultaneous conformation rigidification. Such CTE mechanism is further supported by the single crystal structure analysis, from which 3 D through space electronic communications are uncovered.Besides prompt fluorescence, room temperature phosphorescence(RTP) is also detected from the solids. Moreover, persistent RTP is observed in the powders of exampled poly(amino acids) of ε-poly-L-lysine(.-PLL) after ceasing UV irradiation. These results not only illustrate the feasibility of employing the building blocks of nonaromatic amino acids in the exploration of new luminescent biomolecules, but also provide significant implications for the emissions of peptides and proteins at aggregated or crystalline states. Meanwhile, they may also shed lights on further understanding of autofluorescence from biological systems. | Xiaohong Chen Weijian Luo Huili Ma Qian Peng Wang Zhang Yuan Yongming Zhang | 2018 | Science China Chemistry2018，61，3： | 8 |
| 7 | Adsorption and desorption characteristics of diphenylarsenicals in two contrasting soils显示文摘Diphenylarsinic acid(DPAA) is formed during the leakage of aromatic arsenic chemical weapons in soils,is persistent in nature,and results in arsenic contamination in the field.The adsorption and desorption characteristics of DPAA were investigated in two typical Chinese soils,an Acrisol(a variable-charge soil) and a Phaeozem(a constant-charge soil).Their thermodynamics and some of the factors influencing them(i.e.,initial pH value,ionic strength and phosphate) were also evaluated using the batch method in order to understand the environmental fate of DPAA in soils.The results indicate that Acrisol had a stronger adsorption capacity for DPAA than Phaeozem.Soil DPAA adsorption was a spontaneous and endothermic process and the amount of DPAA adsorbed was affected significantly by variation in soil pH and phosphate.In contrast,soil organic matter and ionic strength had no significant effect on adsorption.This suggests that DPAA adsorption may be due to specific adsorption on soil mineral surfaces.Therefore,monitoring the fate of DPAA in soils is recommended in areas contaminated by leakage from chemical weapons. | Anan Wang Shixin Li Ying Teng Wuxin Liu Longhua Wu Haibo Zhang Yujuan Huang Yongming Luo Peter Christie | 2013 | Journal of Environmental Sciences2013，25，6： | 8 |
| 8 | A new procedure combining GC-MS with accelerated solvent extraction for the analysis of phthalic acid esters in contaminated soils显示文摘An optimized procedure based on gas chromatography-mass spectrometry (GC-MS) combined with accelerated solvent extraction (ASE) is developed for the analysis of six phthalic acid esters (PAEs), which are priority soil pollutants nominated by United States Environmental Protection Agency (USEPA). Quantification of PAEs in soil employs ultrasonic extraction (UE) (USEPA 3550) and ASE (USEPA 3545), followed by clean up procedures involving three different chromatography columns and two combined elution methods. GC-MS conditions under selected ion monitoring (SIM) mode are described and quality assurance and quality control (QA/ QC) criteria with high accuracy and sensitivity for target analytes were achieved. Method reliability is assured with the use of an isotopically labeled PAE, di-n-butyl phthalate-d4 (DnBP-D4), as a surrogate, and benzyl benzoate (BB) as an internal standard, and with the analysis of certified reference materials (CRM). QA/QC for the developed procedure was tested in four PAE-spiked soils and one PAE-contaminated soil. The four spiked soils were originated from typical Chinese agricultural fields and the contaminated soil was obtained from an electronic waste dismantling area. Instrument detection limits (IDLs) for the six PAEs ranged 0.10-0.31 μg·L-1 and method detection limits (MDLs) of the four spiked soils varied from a range of 20-70 μg· kg -1 to a range of 90-290 μg· kg-1. Lineal-iVy of response between 20 μg· L-1 and 2mg.L~ was also established and the correlation coefficients (R) were a11〉0.998. Spiked soil matrix showed relative recovery rates between 75 and 120% for the six target compounds and about 93% for the surrogate substance. The developed procedure is anticipated to be highly applicable for field surveys of soil PAE pollution in China. | Tingting MA Ying TENG Peter CHRISTIE Yongming LUO Yongshan CHEN Mao YE | 2013 | Frontiers of Environmental Science & Engineering2013，7，1： | 8 |
| 9 | Concentrations of Heavy Metals in Suburban Horticultural Soils and Their Uptake by Artemisia selengensis显示文摘A total of 222 surface soil samples and 40 plant samples were collected to investigate the spatial distribution and possible sources of soil heavy metals and to know the uptake and translocation of heavy metals from roots to different plant parts in a representative vegetable production area in the Baguazhou Island, a suburb of Nanjing City, East China. The arithmetic mean values of total Cd, Cr,Cu, Ni, Pb, and Zn concentrations in the soils were 0.314, 133, 41.0, 58.0, 31.8, and 114 mg kg-1, respectively. All of these values were above the topsoil background values in the Nanjing area. Multivariate and geostatistical analyses showed that soil Cd contamination was derived mainly from agricultural practices. In contrast, Cu and Zn were derived mainly from soil parent materials and Pb from atmospheric deposition from highway gasoline stations. Artemisia selengensis, a locally important specialty vegetable, accumulated heavy metals primarily in the edible leaves. The general distribution of heavy metal concentrations in this plant species showed that the highest occurred in the leaves, intermediate in the stems and lowest in the roots. Cd had the highest concentration factor(root-to-soil ratio) and may pose increased health risks in the future to the local population through the consumption of contaminated vegetables. | CUI Xu SUN Xulei HU Pengjie YUAN Cheng LUO Yongming WU Longhua Peter CHRISTIE | 2015 | Pedosphere2015，25，6： | 6 |

| 12 | In situ construction of Z-scheme FeS_(2)/Fe_(2)O_(3) photocatalyst via structural transformation of pyrite for photocatalytic degradation of carbamazepine and the synergistic reduction of Cr(Ⅵ)显示文摘Pyrite is the most abundant sulfide semiconductor mineral with excellent optical properties.However,few reports have investigated its photocatalytic activity because of the low photogenerated carrier separation efficiency.In this work,a Z-scheme FeS_(2)/Fe_(2)O_(3)composite photocatalyst was fabricated in situ via structural transformation of pyrite through heat treatment.A remarkably enhanced photocatalytic performance was observed over the FeS_(2)/Fe_(2)O_(3)composite photocatalyst.Compared with the pristine pyrite,the degradation efficiency of carbamazepine(CBZ)reached 65%at the added hexavalent chromium(Cr(Ⅵ))concentration of 20 mg/L and the Cr(Ⅵ)was nearly completely reduced in the mixed system using FeS_(2)/Fe_(2)O_(3)within 30 min under simulated solar light irradiation.The enhanced photocatalytic activity can be attributed to the efficient separation and transfer of photogenerated carriers in the FeS_(2)/Fe_(2)O_(3)composite photocatalyst.This facilitated the generation of·OH,hole(h^(+))and·O_(2)^(-)species,which participated in the photocatalytic reaction with CBZ.Based on the measurement of the active species and electric properties,a Z-scheme electron transfer pathway was proposed for the FeS_(2)/Fe_(2)O_(3)composite photocatalyst.This work broadens the application potential of pyrite in environmental remediation. | Qian Guo Guangbei Tang Wenjie Zhu Yongming Luo Xiaoya Gao | 2021 | Journal of Environmental Sciences2021，33，3： | 4 |

| 14 | Impacts of land use and salinization on soil inorganic and organic carbon in the middle-lower Yellow River Delta显示文摘Soil inorganic carbon(SIC)is an important reservoir of carbon(C)in arid,semi-arid,and semi-humid regions.However,knowledge is incomplete on the dynamics of SIC and its relationship with soil organic C(SOC)under different land use types in the semi-humid region,particularly in coastal zones impacted by soil salinization.We collected 170 soil samples from 34 profiles across various land use types(maize-wheat,cotton,paddy,and reed)in the middle-lower Yellow River Delta(YRD),China.We measured soil pH,electrical conductivity(EC),water-soluble salts,and SOC and SIC contents.Our results showed significant differences in both SOC and SIC among land use types.The dry cropland(maize-wheat and cotton)soils had significantly higher SOC and SIC densities(4.71 and 15.46 kg C m^(-2),respectively)than the paddy soils(3.28 and 14.09 kg C m^(-2),respectively)in the 0–100 cm layer.Compared with paddy soils,reed soils contained significantly higher SOC(4.68 kg C m^(-2))and similar SIC(15.02 kg C m^(-2))densities.There was a significant positive correlation between SOC and SIC densities over a 0–100 cm soil depth in dry cropland soils,but a negative relationship in the paddy soils.On average,SOC and SIC densities under maize-wheat cropping were 15%and 4%lower,respectively,in the salt-affected soils in the middle-lower YRD than the upper YRD.This study indicated that land use types had great influences on both SOC and SIC and their relationship,and salinization had adverse effect on soil C storage in the YRD. | Yang GUO Xiujun WANG Xianglan LI Minggang XU Yuan LI Haonan ZHENG Yongming LUO Pete SMITH | 2021 | Pedosphere2021，31，6： | 4 |
| 15 | Black carp growth hormone gene transgenic allotetraploid hybrids of Carassius auratus red var. (♀)×Cyprinus carpio (♂)显示文摘Ecological safety is a major consideration in the commercialization of transgenic fish. Development of sterile transgenic triploid fish through hybridization of transgenic tetraploid fish and transgenic diploid fish is a feasible way to solve this problem. The 'all-fish' transgene, pbcAbcGHc, containing the black carp β-actin gene promoter and the open reading frame (ORF) of the black carp growth hormone (GH) gene was constructed and introduced into fertilized eggs of allotetraploid fish through microinjection. Contrast cultivation results showed that the growth rate of 150 day-old P 0 black carp GH gene transgenic allotetraploid fish was much higher than that of controls. Sixty 150 day-old transgenic allotetraploid fish were assayed by PCR for transgene integration and 90% of fish were positive for the transgene. The transgene was detected in 13 of 20 sperm samples from male transgenic allotetraploid fish. RT-PCR detected transcription of the exogenous black carp GH gene in the muscle, liver, kidney and ovaries of the largest transgenic allotetraploid fish. This study has developed P 0 black carp GH gene transgenic allotetraploid fish with a highly increased growth rate, which provides a solid foundation for the establishment of a pure line of transgenic allotetraploid fish and for the large scale production of sterile transgenic triploid fish. | FENG Hao FU YongMing LUO Jian WU Hui LIU Yun LIU ShaoJun | 2011 | Science China(Life Sciences)2011，54，9： | 3 |
| 16 | The integration characteristics of the exogenous growth hormone gene in a transgenic common carp(Cyprinus carpio L.) with fast-growth performance显示文摘The genetic stability and expression efficiency of exogenous genes in transgenic animals are closely related to integration site and copy number. In our laboratory, by transgenic manipulation and subsequent test crosses, we established an ‘‘all-fish'' growth hormone(GH)transgenic common carp family that exhibits fast growth.In this present study, genome walking, real-time quantitative polymerase chain reaction, and fluorescence in situ hybridization techniques were applied to identify the integration characteristics of the exogenous grass carp GH gene in the transgenic common carp. The exogenous GH genes, in the form of two complete and one incomplete tandem repeats, were found to have integrated into an ATrich region near the end of a chromosome pair. We hypothesize that the high efficiency of exogenous GH gene expression might be due to the low copy number in the genome and the AT-rich integration site. | Ji Chen Qing Luo Hairong Bao Lanjie Liao Yongming Li Zuoyan Zhu Yaping Wang Wei Hu | 2015 | Science Bulletin2015，60，19： | 3 |
| 17 | The return and loss of litter phosphorus in different types of sand dunes in Horqin Sandy Land,northeastern China显示文摘Litter phosphorus(P) return is important to maintain the P cycle and balance in the sandy land of arid areas.In this study,we determined the loss and return of litter P in sand dune areas and elucidated their relationship.We investigated litter production and litter P amount,and simulated leaf litter moving dynamics to understand the relationships between the loss of litter P and the total litter P,and between the return of litter P and the total litter P in active(AD),semi-stabilized(SSD) and stabilized(SD) dunes in Inner Mongolia,northeastern China.The vegetation litter P was 12.6,94.5,and 201.6 mg P/m2 in AD,SSD,and SD,respectively.A significant movement and loss of leaf litter P with time occurred on the three types of sand dunes.As a result,the loss of P was 7.4,46.9,and 69.8 mg P/m2 and the return of P was 5.5,47.6,and 131.8 mg P/m2 in AD,SSD,and SD,respectively.The relationship between both loss and return of P and total litter P in AD,SSD,and SD was revealed by linear regression.The slope of the regression line indicated the rate of loss or return of litter P.From AD to SD,the loss rate showed a declining slope(0.52,0.32,and 0.17 for AD,SSD,and SD,respectively),and the return rate showed a rising slope(0.48,0.67,and 0.83 for AD,SSD,and SD,respectively).The loss of litter P should be regarded in the local management of vegetation and land in sand dune areas.Improved vegetation restoration measures are necessary to decrease litter P loss to maintain the stability of ecosystems in sand dune areas. | QuanLai ZHOU DeMing JIANG ZhiMin LIU Alamusa XueHua LI YongMing LUO HongMei WANG | 2012 | Journal of Arid Land2012，4，4： | 3 |
| 18 | Refinement of Methodology for Cadmium Determination in Soil Micro-Arthropod Tissues显示文摘Highly precise and reliable determination of heavy metals in soil micro-arthropod tissues remains a challenge because of the small size of the animals and their typical low abundance in metal-contaminated agricultural soils. The present study sought to develop a method for cadmium(Cd) determination in soil micro-arthropods by optimizing the sample digestion procedure, reducing sample weight, modifying sample pre-treatment and validating the methodology with field samples. The optimized digestion conditions comprised a sample mass of 50–150 μg, digestion reagent of nitric acid:hydrogen peroxide(3:1), digestion temperature of 105℃,digestion period of 3 h and digestion volume of 30 μL. Defecation of the standard Collembola Folsomia candida(92 h) and the indigenous Collembola Onychiurus yodai(42 h) and ultrasonic cleaning of F. candida increased the accuracy of Cd determination.The recovery of Cd using the refined procedure was 98.9% and the limits of detection and quantification were 0.002 and 0.008 μg L^(-1), respectively. The within-batch precision values were < 3%. The Cd concentrations in the tissues of the Collembola Isotoma sp.collected from a range of metal-contaminated fields determined by the improved method were consistent with the Cd concentrations in the field soils. The results indicate that the optimized method can be used for more accurate or reliable determination of Cd concentrations in soil micro-arthropod tissues. | ZHU Dong KE Xin WU Longhua HUANG Yujuan Peter CHRISTIE LUO Yongming | 2017 | Pedosphere2017，27，3： | 3 |

| 20 | Optimization of Ex-Situ Washing Removal of Polycyclic Aromatic Hydrocarbons from a Contaminated Soil Using Nano-Sulfonated Graphene显示文摘Ex-situ soil washing technology offers advantages such as speed and efficiency of remediation and range of application and has been developed to conform with legal requirements and best management practices in USA and some European countries. In this study,nano-sulfonated graphene(SGE) was used as a washing agent to evaluate different processing(washing) parameters for the ectopic leaching removal of polycyclic aromatic hydrocarbons(PAHs) from a coking plant soil. X-ray photoelectron spectroscopy(XPS) and fourier transform infrared spectroscopy(FTIR) were used to analyze the characteristics of the SGE tested. The results showed that SGE had a strong adsorption capacity for PAHs through the role of π-π, H-π, and anion-π interactions. The washing parameters, an SGE concentration of 2 000 mg L^(-1), a liquid/soil(L/S) ratio of 10:1, and 4 cycles of successive washing, were set to arrive to the optimum condition for achieving more than 80% of PAH removal. Under the optimum condition, the PAH removal rate decreased with increasing ring numbers. After one washing cycle at SGE concentration of 2 000 mg L^(-1) and L/S ratio of 10:1, the PAH removal rate of the SGE tested was much higher than that of Tween 80(TW80) or methyl-β-cyclodextrin(MCD)(P < 0.01). Therefore, SGE is a promising material for the nanoremediation of PAH-contaminated soils. | GAN Xinhong TENG Ying REN Wenjie MA Jun Peter CHRISTIE LUO Yongming | 2017 | Pedosphere2017，27，3： | 3 |
