| 1 | ^(15)N isotope fractionation in an aquatic food chain:Bellamya aeruginosa(Reeve) as an algal control agent显示文摘15N isotope tracer techniques and ecological modeling were adopted to investigate the fractionation of nitrogen,its uptake and transformation in algae and snail(Bellamya aeruginosa Reeve).Different algal species were found to differ in their uptake of nitrogen isotopes.Microcystis aeruginisa Ktz.demonstrated the greatest 15N accumulation capacity,with the natural variation in isotopic ratio(δ 15N) and the isotope fractionation factor(ε,‰) being the highest among the species investigated.The transformation and utilization of 15N by snails differed depending on the specific algae consumed(highest for Chlorella pyrenoidosa Chick.,lowest for M.aeruginisa).When snails was seeded in the experimental pond,the algae population structure changed significantly,and total algal biomass as well as the concentration of all nitrogen species decreased,causing an increase in water transparency.A model,incorporating several chemical and biological parameters,was developed to predict algal biomass in an aquatic system when snails was present.The data collected during this investigation indicated that the gastropods such as snails could significantly impact biological community and water quality of small water bodies,suggesting a role for biological control of noxious algal blooms associated with eutrophication. | Shiqun Han Shaohua Yan Kaining Chen Zhenhua Zhang Rengel Zed Jianqiu Zhang Wei Song Haiqin Liu | 2010 | Journal of Environmental Sciences2010，22，2： | 14 |

| 5 | Comparison of three flocculants for heavy cyanobacterial bloom mitigation and subsequent environmental impact显示文摘Cyanobacteria can accumulate as a heavy biomass on the leeward side of large eutrophic lakes,posing a potential threat to public health.The mitigating capacity of three flocculants and their potential impacts on the major environmental features of water and sediments was evaluated.Results indicate that polyaluminum chloride(PAC)and ferric chloride(FeCl)are efficient flocculants that can rapidly mitigate cyanobacterial blooms with chlorophyll-a concentrations higher tnan 1500 ug/L within 15 min.In comparison,cationic starch with chitosan could only treat cyanobacterial blooms in chlorophyll-a concentrations of less than 200μg/L.The addition of FeClcaused a decline in the pH value,while dissolved oxygen in the water column dropped to 2 mg/L during cationic starch with chitosan treatment for a high cyanobacterial biomass group.Thus,a combination of flocculants and oxygenators should be considered when treating high-concentration cyanobacterial blooms for emergency purposes.Additionally,the cell lysis of cyanobacteria caused by cationic starch with chitosan can result in an increase in total dissolved phosphorus and total dissolved nitrogen.Furthermore,the high accumlation of nutrients in sediments after the settling of cyanobacteria can cause high internal phosphorus pollution.The increase in the total organic carbon of the sediments can threaten lake restoration achieved by planting submerged macrophytes. | Kaixuan LIU Lei JIANG Jinsheng YANG Shuzhan MA Kaining CHEN Yufeng ZHANG Xiaoli SHI | 2022 | Journal of Oceanology and Limnology2022，40，5： | 1 |

| 8 | The impact of the accumulation of algal blooms on reed wetlands in the littoral zones of Chaohu Lake显示文摘In a large eutrophic lake,the littoral zone is normally an area with high-density elevated aquatic plant life,including algal blooms,where the presence of reed wetlands allows the accumulation of algae.In this study,the impact of accumulated algal blooms in reed wetlands in the littoral zone s of Chaohu Lake was investigated seasonally from 2018 to 2019.The concentrations of chlorophyll a(Chl a),total nitrogen(TN),and total phosphorus(TP)were much higher in the reed-covered littoral zones(RCLZ)than in the unvegetated littoral zones(ULZ),indicating that more algal biomass was trapped and accumulated in the RCLZ.Algal biomass could be horizontally transported to downwind littoral zones under low wind speeds,favoring the establishment of blooms.Algal accumulation levels were highest in summer due to high water temperatures and algal biomasses.Likewise,the northern littoral zones were conducive to the development of large algal blooms because of the wind pattern.The values of TN,TP,Chl a,and loss on ignition in surface sediments were higher in the RCLZ than in the ULZ.Moreover,the diffusive fluxes of ammonium and soluble reactive pho sphorus were also higher in the RCLZ than in the ULZ.Considering the capability of reed wetlands to trap algae,mechanical salvage and other physical methods should be adopted to eliminate algal biomass when massive blooms accumulate in the RCLZ. | Shuzhan MA Yue WU Siwen CHEN Bingfa CHEN Cheng LIU Xiaozhi GU Xiaoli SHI Kaining CHEN | 2022 | Journal of Oceanology and Limnology2022，40，5： | 0 |
| 9 | Homojunction and ohmic contact coexisting carbon nitride for efficient photocatalytic hydrogen evolution显示文摘Carbon nitride(CN)has attracted intensive attention as a visible light photocatalyst,but the rapid recombination of photogenerated charge carriers limits its photocatalytic activity.Herein,we develop a new strategy to construct both homojunction and ohmic junction into CN via selectively introducing metallized CN(MCN),which leads to rapid separation and transfer of photogenerated charge carriers.The polymerization of urea in the presence of KOH creates CN homojunction with amino and cyano groups.The subsequent molten salt treatment induces a new type of cyano-terminated CN that can be converted to MCN through photodoping,forming homojunction and ohmic contact coexisting CN(HOCN).The formed HOCN photocatalyst exhibits a high photocatalytic H_(2)evolution rate of 18.5 mmol·g^(-1)·h^(-1)under visible light irradiation,45-fold higher than that of bulk CN.This strategy provides a new idea for designing ohmic contact between semiconductor and metal,and realizing efficient photocatalysis by improving charge separation and transfer. | Xiao Fang Lu Chen Hongrui Cheng Xiaoqiong Bian Wenhao Sun Kaining Ding Xinghe Xia Xin Chen Jiefang Zhu Yuanhui Zheng | 2023 | Nano Research2023，16，7： | 0 |
