| 1 | Distribution and characteristic of PAHs in snow of Fildes Peninsula显示文摘Polycyclic aromatic hydrocarbons (PAHs) investigation in different matrices has been reported largely,whereas reports on snow samples were limited.Snow,as the main matrix in the polar region,has an important study meaning.PAHs in snow samples were analyzed to investigate the distribution and contamination status of them in the Antarctic,as well as to provide some references for global migration of PAHs.Snow samples collected in Fildes Peninsula were enriched and separated by solid-phase membrane disks and eluted by methylene dichloride,then quantified by gas chromatography/mass spectrometry.All types of PAHs were detected except for Benzo(a)pyrene.Principal component analysis method was applied to characterize them.Three factors (Naphthalene,Fluorene and Phenanthrene) accounted for 60.57%,21.61% and 9.80%,respectively.The results showed that the major PAHs sources maybe the atmospheric transportation,and the combustion of fuel in Fildes Peninsula.The comparison of concentration and types of PAHs between accumulated snow and fresh snow showed that the main compound concentrations in accumulated snow samples were higher than those in fresh ones.The risk assessment indicated that the amount of PAHs in the snow samples would not lead to ecological risk. | Guangshui Na Chunyang Liu Zhen Wang Linke Ge Xindong Ma Ziwei Yao | 2011 | Journal of Environmental Sciences2011，23，9： | 8 |
| 2 | Occurrence and bioaccumulation of polybrominated diphenyl ethers in sediments and paddy ecosystems of Liaohe River Basin, northeast China显示文摘Concentrations of 16 polybrominated diphenyl ether(PBDE) congeners were measured in river sediments, paddy soils and three species of paddy-field organisms(crab, loach and carp) collected from the Liaohe River Basin, northeastern China. The total contents of PBDEs(∑_(16)PBDEs) in sediments and paddy soils were in the ranges of 273.4–3246.3 pg/g dry weight(dw), and 192.1–1783.8 pg/g dw, respectively. BDE 209 was the dominant congener both in sediments and paddy soils. The concentrations of ∑_(16)PBDEs in sediments were significantly higher than those in the adjacent paddy soils, indicating a potential transport of PBDEs from river to paddy ecosystems via river water irrigation. The biota–soil accumulation factor(BSAF) was calculated as the ratio between the lipid-normalized concentration in paddyfield organisms and the total organic carbon-normalized concentration in paddy soil. The average BSAF values of ∑15PBDEs followed the sequence of crab(3.6) > loach(3.3) > carp(2.1). BDE 154 had the highest BSAF value, and a parabolic trend between BSAF values of individual PBDE congeners and their log KOWvalues was observed. In view of the fact that crab had the larger BSAF value and higher lipid content, the ecological risk and health risk for crab cultivation in paddy fields should be of particular concern. | Xindong Ma Haijun Zhang Wenjun Yao Wen Guo Depeng Li Ziwei Yao Jiping Chen | 2016 | Journal of Environmental Sciences2016，28，5： | 6 |

| 4 | Atmospheric concentration characteristics and gas/particle partitioning of PCBs from the North Pacific to the Arctic Ocean显示文摘Polychlorinated biphenyls(PCBs) were measured in atmospheric samples collected from the North Pacific to the Arctic Ocean between July and September 2012 to study the atmospheric concentration characteristics of PCBs and their gas/particle partitioning. The mean concentration of 26 ∑PCBs(vapor plus particulate phase)(∑PCBs) was 19.116 pg/m3 with a standard deviation of 13.833 pg/m3. Three most abundant congeners were CB-28,-52 and-77, accounting for 43.0% to ∑PCBs. The predominance of vapor PCBs(79.0% to ∑PCBs) in the atmosphere was observed. PCBs were negative correlated with the latitudes and inverse of the absolute temperature(1/T). The significant correlation for most congeners was also observed between the logarithm of gas/particle partition coefficient(log KP) and 1/T. Shallower slopes(from-0.15 to-0.46, average-0.27) were measured from the regression of the logarithm of sub-cooled liquid vapor pressures(logpo L) and log KP for all samples. The difference of the slopes and intercepts among samples was insignificant(p>0.1), implying adsorption and/or absorption processes and the aerosol composition did not differ significantly among different samples. By comparing three models, the J-P adsorption model, the octanol/air partition coefficient(KOA) based model and the soot-air model, the gas/particle partitioning of PCBs in the Arctic atmosphere was simulated more precisely by the soot-air model, and the adsorption onto elemental carbon is more sensitive than the absorption into organic matters of aerosols, especially for lowchlorinated PCB congeners. | WANG Zhen NA Guangshui GAO Hui WANG Yanjie YAO Ziwei | 2014 | Acta Oceanologica Sinica2014，33，12： | 4 |
| 5 | The osmolyte-producing endophyte Streptomyces albidoflavus OsiLf-2 induces drought and salt tolerance in rice via a multi-level mechanism显示文摘Drought and salinity are major environmental stresses that impair crop growth and productivity worldwide. Improving drought and salt tolerance of crops with microbial mutualists is an effective and environmentally sound strategy to meet the demands of the ever-growing world population. In the present study, we found that the Streptomyces albidoflavus Osi Lf-2, a moderately salt-tolerant endophytic actinomycete, produced abundant osmolytes, including proline, polysaccharides, and ectoine. Inoculation with Osi Lf-2 increased the osmotic-adjustment ability of the rice host by increasing the proline content(by250.3% and 49.4%) and soluble sugar(by 20.9% and 49.4%) in rice under drought and salt conditions, relative to the uninoculated control. Osi Lf-2 increased stress responses in the rice host at the physiological and biochemical levels(photosynthesis efficiency, osmolytes and antioxidant content), and the gene level(osmolytes synthesis, stress-responsive and ion-transport related genes), raising rice yields under both greenhouse and saline–alkaline soil conditions. The use of endophytic actinomycetes offers a promising biotechnological approach to developing stress-tolerant plants. | Shuqi Niu Yan Gao Huixian Zi Ying Liu Xuanming Liu Xianqiu Xiong Qingqing Yao Ziwei Qin Ning Chen Liang Guo Yuanzhu Yang Peng Qin Jianzhong Lin Yonghua Zhu | 2022 | The Crop Journal2022，10，2： | 3 |
| 6 | Determination of dioxin-like polychlorinated biphenyls in soil and moss from Fildes Peninsula,Antarctica显示文摘Dioxin-like polychlorinated biphenyls(PCBs) are a class of toxic and persistent chemicals that are often found in the environment.The determination of dioxin-like PCBs in Fildes Peninsula,Antarctica,is reported in this paper.Dioxin-like PCBs were widely distributed in Antarctic soil and moss with concentration of 2.23-27.2 pg/g in soil and 10.4-812 pg/g in moss.The highest concentrations were found in the Ardley Island area and the lowest concentrations on the west coast.The contribution of PCB-118 to the ∑12PCBs ranged from 36.0% to 69.6% in soil,and 17.2% to 43.4% in moss.The congener specific patterns in soil and moss were similar.Long-range atmospheric transport is thought to be the main source of PCBs detected on King George Island.The ∑12PCBs toxic equivalent(TEQ) in soil was 0.400×10?3 to 516×10?3 pg(TEQ)/g with a mean value of 147×10?3 pg(TEQ)/g.PCB-126 had the largest contribution(81.1%) to the ∑12PCBs TEQ in soil.The ∑12PCBs TEQ in moss ranged from 2.90×10?3 to 1.19 pg/g with a mean value of 0.482 pg/g.PCB-126 was also the largest contributor(91.4%) to the ∑12PCBs TEQ in moss.The mean TEQ in moss was about 40 times that in soil. | WANG Qiang SHI YeHong HU JianXin YAO ZiWei FANG XueKun DONG YiAn | 2012 | Chinese Science Bulletin2012，57，9： | 3 |
| 7 | Distribution characteristics and indicator significance of Dechloranes in multi-matrices at Ny-lesund in the Arctic显示文摘In recent years, Dechloranes have been widely detected in the environment around the world.However, understanding and knowledge of Dechloranes in remote regions, such as the Arctic,remain lacking. Therefore, the concentrations of 5 Dechloranes in surface seawater, sediment,soil, moss, and dung collected from Ny-lesund in the Arctic were measured with the concentrations 93 pg/L, 342, 325, 1.4, and 258 pg/g, respectively, which were much lower than those in Asian and European regions. The mean ratios of anti-Dechlorane Plus(DP) to total DP(fanti) in seawater, sediment, soil, moss, dung, and atmospheric samples were 0.36, 0.21, 0.18,0.27, 0.66, and 0.43, respectively. Results suggested that the main source of DP in seawater,sediment, soil, and moss was long-range atmospheric transport. However, the ratio identified in dung was different, for which the migration behavior of the organism is probably the main source of DP. | Guangshui Na Wei Wei Shiyao Zhou Hui Gao Xindong Ma Lina Qiu Linke Ge Chenguang Bao Ziwei Yao | 2015 | Journal of Environmental Sciences2015，27，2： | 3 |

| 9 | Long-term nutrient variation trends and their potential impact on phytoplankton in the southern Yellow Sea,China显示文摘The concentration and composition of nutrients,such as N,P,and Si,respond to biogeochemical processes and in turn,impact the phytoplanktons'community structure and primary production.In this study,historical data was systematically analyzed to identify long-term variations in nutrient trends,red tide frequency,phytoplankton community abundance,and dominant species succession in the southern Yellow Sea(SYS).Results showed that N/P concentration ratios dramatically increased as a function of increasing dissolved inorganic nitrogen concentrations,and Si/N concentration ratios were generally larger than 1,indicating that N limitation morphed to P limitation and potentially to Si limitation,which impacted the phytoplankton community.Furthermore,inter-annual trends over the past 50 years show that phytoplankton community abundance has been higher in spring and summer,relative to autumn and winter.Moreover,with respect to red tide frequency,diatom abundance gradually decreased,while that of dinoflagellates gradually increased.Dominant species succession showed that the phytoplankton community exhibited an evident tendency to transform from diatoms to dinoflagellates.These research results clearly depict the presence of an important correlation between the phytoplankton community and nutrient structure in the SYS. | Yan Wang Yongjian Liu Hao Guo Haibo Zhang Dongmei Li Ziwei Yao Xiaocheng Wang Chuan Jia | 2022 | Acta Oceanologica Sinica2022，41，6： | 1 |

| 11 | Geochronology and Petrogenesis of Granitoid Intrusions in the Feidong District, Southern Tan-Lu Fault Zone, China显示文摘The Feidong district is located in the southern segment of the Tan-Lu fault zone that separates the South China Block(NCB)from the North China Craton(NCC).We report zircon U-Pb geochronology and Hf isotope data,as well as whole-rock geochemistry for Xishanyi granodiorite and Jianshan granite in the Feidong district.Zircon U-Pb dating results show that the emplacement ages of the Xishanyi and Jianshan intrusions are 124±3 Ma and 130±1 Ma respectively,coeval with magmatic events linked to large-scale lithospheric thinning in eastern China.The whole-rock geochemistry of the Xishanyi and Jianshan intrusions demonstrate that they are peraluminous,high potassium calc-alkaline I-type granites with adakitic characteristics.Both intrusions underwent weak crustal assimilation during emplacement.The in situ zirconε(Hf)(t)values of the Xishanyi granodiorites range from-26.4 to-21.8,with T(DM2)model ages of 2552 to 2841 Ma.The in situ zirconε(Hf)(t)values of the Jianshan granite are from-27.5 to-23.0 with T(DM2)model ages of 2632 to 2904 Ma.The peak age of inherited zircon grains from the Xishanyi granodiorite and the Jianshan granite were^2.07 Ga and^1.94 Ga,respectively.After compared with the regional magmatism,we suggest that both the Xishanyi and Jianshan granitoid intrusions were derived from partial melting of the NCC lower crust. | FU Xiang ZHANG Dayu YAO Ziwei REN Kangda DENG Yufeng LI Jiahao JIANG Ren YUAN Feng | 2020 | Acta Geologica Sinica(English Edition)2020，94，6： | 1 |
| 12 | A multi-modal clustering method for traditonal Chinese medicine clinical data via media convergence显示文摘Media convergence is a media change led by technological innovation.Applying media convergence technology to the study of clustering in Chinese medicine can significantly exploit the advantages of media fusion.Obtaining consistent and complementary information among multiple modalities through media convergence can provide technical support for clustering.This article presents an approach based on Media Convergence and Graph convolution Encoder Clustering(MCGEC)for traditonal Chinese medicine(TCM)clinical data.It feeds modal information and graph structure from media information into a multi-modal graph convolution encoder to obtain the media feature representation learnt from multiple modalities.MCGEC captures latent information from various modalities by fusion and optimises the feature representations and network architecture with learnt clustering labels.The experiment is conducted on real-world multimodal TCM clinical data,including information like images and text.MCGEC has improved clustering results compared to the generic single-modal clustering methods and the current more advanced multi-modal clustering methods.MCGEC applied to TCM clinical datasets can achieve better results.Integrating multimedia features into clustering algorithms offers significant benefits compared to single-modal clustering approaches that simply concatenate features from different modalities.It provides practical technical support for multi-modal clustering in the TCM field incorporating multimedia features. | Jingna Si Ziwei Tian Dongmei Li Lei Zhang Lei Yao Wenjuan Jiang Jia Liu Runshun Zhang Xiaoping Zhang | 2023 | CAAI Transactions on Intelligence Technology2023，8，2： | 0 |
| 13 | PH_3 monitoring in Arctic and Dalian bay areas显示文摘In this paper,we use pre-column 2 times low-temperature cryo-trap enrichment—gas chromatography(GC) /nitrogen and phosphoms detector(NPD)to detect and analyze phosphine in Arctic pole area forthe first time.The results show phosphine exists in all of the samples in Arctic pole biosphere and phosphineconcentration in Arctic atmosphere is between 18.54~132.18 ng/m^3,almost the same as that inAntarctic atmosphere;phosphine concentration in Dalian bay sea surface sediments is between 116.8~554.3 ng/kg,almost the same as that reported in Jiao-zhou bay.Our research of phosphine will shednew light on the mechanisms showing how the phosphorus supplement influences the biogeochemical cycleand global warming. | 封颖 Wang Qiang Yao Ziwei Geng Jinju | 2010 | High Technology Letters2010，16，4： | 0 |
| 14 | Shipborne oceanic high-spectral-resolution lidar for accurate estimation of seawater depth-resolved optical properties显示文摘Lidar techniques present a distinctive ability to resolve vertical structure of optical properties within the upper water column at both day-and night-time.However,accuracy challenges remain for existing lidar instruments due to the ill-posed nature of elastic backscatter lidar retrievals and multiple scattering.Here we demonstrate the high performance of,to the best of our knowledge,the first shipborne oceanic high-spectral-resolution lidar(HSRL)and illustrate a multiple scattering correction algorithm to rigorously address the above challenges in estimating the depth-resolved diffuse attenuation coefficient Kd and the particulate backscattering coefficient bbp at 532 nm.HSRL data were collected during day-and night-time within the coastal areas of East China Sea and South China Sea,which are connected by the Taiwan Strait.Results include vertical profiles from open ocean waters to moderate turbid waters and first lidar continuous observation of diel vertical distribution of thin layers at a fixed station.The root-mean-square relative differences between the HSRL and coincident in situ measurements are 5.6%and 9.1%for Kd and bbp,respectively,corresponding to an improvement of 2.7-13.5 and 4.9-44.1 times,respectively,with respect to elastic backscatter lidar methods.Shipborne oceanic HSRLs with high performance are expected to be of paramount importance for the construction of 3D map of ocean ecosystem. | Yudi Zhou Yang Chen Hongkai Zhao Cedric Jamet Davide Dionisi Malik Chami Paolo Di Grolamo James H.Churnside Aleksey Malinka Huade Zhao Dajun Qiu Tingwei Cui Qun Liu Yatong Chen Sornsiri Phongphattarawat Nanchao Wang Sijie Chen Peng Chen Ziwei Yao Chengfeng Le Yuting Tao Peituo Xu Xiaobin Wang Binyu Wang Feitong Chen Chuang Ye Kai Zhang Chong Liu Dong Liu | 2022 | Light(Science & Applications)2022，11，10： | 0 |
| 15 | Matrix-bound phosphine in Ny-Alesund Area of Arctic显示文摘Phosphine,a ubiquitous trace gas in the atmosphere,acts as a carrier of gasous phosphorus in thebiogeochemical cycle.The research of phosphine will show new light on the mechanisms of how the phos-phorus supplement influence the biogeochemical cycle and global warming.In this paper,we detect thephosphine in Arctic Pole area for the first time.The result shows that matrix-bound phosphine(MBP)ex-ists in all the samplings.Phosphine distributions varied with different environmental origins.Averagephosphine concentrations in tundra soil,lake sediments,sea sediments,seabird-droppings and deerguanos were 14.17ng/kg dry,35.44 kg dry,67.20 kg dry,32.9 ng/kg dry,and 25.52 ng/kg dry re-spectively.Correlation analysis shows that there is an obviously positive correlation between Porg andMBP.It could be concluded that anaerobic decomposition of Porg and the mechano-chernistry action of therock probably are the possible reasons explaining the mechanism of MBP production in Arctic Pole area. | 封颖 Wang Qiang Yao Ziwei Geng Jinju | 2009 | High Technology Letters2009，15，3： | 0 |
| 16 | Characteristics of implicit schemas in patients with major depressive disorder显示文摘Background Many psychotherapy theories emphasise the importance of self-schema and other-schema,but most previous studies focused on the explicit self-schema in major depressive disorder(MDD).However,the limited studies of implicit self-schema in MDD have shown inconsistencies in their findings.Furthermore,only a few studies have investigated the implicit other-schema,and the pathway illustrating how implicit schemas influence depression remains unclear.Aims The primary aim of our study was to explore the characteristics of implicit self-schema and otherschema in patients with MDD.We also examine the chain-mediating effect of attachment relationships and interpersonal trust.Methods The present study included 88 patients with MDD and 88 healthy controls(HCs).The Hamilton Depression Rating Scale-17,Experiences in Close Relationships Inventory—Revised Questionnaire,Trust Scale and the Extrinsic Affective Simon Task(EAST)were used to assess depressive symptoms,attachment relationships,interpersonal trust and implicit schemas,respectively.Paired sample t-test was used to compare the reaction time(RT)for positive and negative words within the two groups.Analysis of covariance was used to explore the difference between two groups from the perspective of implicit schemas and interpersonal patterns.The chain mediation model was verified by bootstrap.Results(1)For interpersonal patterns,patients with MDD scored significantly higher on attachment anxiety(F=82.150,p<0.001)and attachment avoidance(F=23.192,p<0.001)and scored significantly lower on the predictability(F=30.297,p<0.001),dependence(F=39.728,p<0.001)and faith(F=60.997,p<0.001)dimensions of interpersonal trust.(2)As for implicit schemas,no significant difference was found between the RT for positive self-words and negative self-words in patients with MDD(t=−1.056,p=0.294).However,the HC responded faster to positive self-words than negative self-words(t=−3.286,p=0.001).The RT for positive other-words and negative other-words were significantly different in both patients with MDD(t=2.943,p=0.004)and HCs(t=−2.482,p=0.015),with opposite directions.The EAST effect of other-schema in patients with MDD was significantly different from that in HCs(F=13.051,p<0.001).(3)For the total sample,the EAST effect of other-schema significantly correlated with attachment avoidance,interpersonal trust and depressive symptoms.Attachment avoidance and interpersonal trust were the chain mediators between the EAST effect of other-schema and depressive symptoms(95%CI:−0.090 to−0.008).However,no significant results were found for the EAST effect of other-schema when correlation and mediation analyses were performed for HCs and patients with MDD separately.Conclusions This study verified that patients with MDD have abnormal interpersonal patterns and negative implicit schemas.However,no mediating effect of attachment relationships and interpersonal trust was found. | Jiayu Yao Qingqing Lin Ziwei Zheng Shuangyi Chen Yuan Wang Wenhui Jiang Jianyin Qiu | 2022 | General Psychiatry2022，35，3： | 0 |
| 17 | Pollination Biology of the Endangered Herbal Medicines Dendrobium chrysotoxum(Orchidaceae)显示文摘Pollination biology studies of the endangered herbal medicines Dendrobium chrysotoxum were conducted in natural pollination conditions using flower observation,pollinator observation and artificial pollination experiments.Populations of D.chrysotoxum with fragrance and nectar were pollinated by Ctenoplectra davidi Valhalla(Hymenoptera:Apidae)species.The floral structure of D.chrysotoxum adapted precisely to its pollinators.Flowers had a low capsule setting(0.17%)under natural conditions.However,compared to open pollination,artificial pollination experiments showed a significant increase in capsule setting,and D.chrysotoxum was cross-compatible and self-compatible,but there was pollinator limitation also.This study will provide important information for the preservation of this endangered species. | Kai Luo Yanbing Bai Yan Jiang Guiling Li Min Jia Yongguo He Zhijun Yao Ziwei Xiao Xiaoqiong Liu Wenjie Liu Shanshan Yin Zesheng Li | 2023 | Phyton-International Journal of Experimental Botany2023，92，7： | 0 |
| 18 | A pyrazine based metal-organic framework for selective removal of copper from strongly acidic solutions显示文摘The selective capture of copper from strongly acidic solutions is of vital importance from the perspective of sustainable development and environmental protection.Metal organic frameworks(MOFs)have attracted the interest of many scholars for adsorption due to their fascinating physicochemical characteristics,including adjustable structure,strong stability and porosity.Herein,pz-UiO-66 containing a pyrazine structure is successfully synthesized for the efficient separation of copper from strongly acidic conditions.Selective copper removal at low pH values is accomplished by using this material that is not available in previously reported metal–organic frameworks.Furthermore,the material exhibits excellent adsorption capacity,with a theoretical maximum copper uptake of 247 mg/g.As proven by XPS and FT-IR analysis,the coordination of pyrazine nitrogen atoms with copper ions is the dominant adsorption mechanism of copper by pz-UiO-66.This work provides an opportunity for efficient and selective copper removal under strongly acidic conditions,and promises extensive application prospects for the removal of copper in the treatment for acid metallurgical wastewater. | Jiachuang Shao Penghui Shao Mingming Peng Min Li Ziwei Yao Xiuqin Xiong Caiting Qiu Yufan Zheng Liming Yang Xubiao Luo | 2023 | Frontiers of Environmental Science & Engineering2023，17，3： | 0 |
