  [Toxicological effects and risk assessment of lanthanum ions on leaves of Viciafaba L.seedlings]Abstract:Viciafaba L.seedlings were hydroponically cultivated in 0-12 mg/L of extraneous lanthanum (La) for 15 d to investigate ecotoxicological effects and risk assessment of rare earth elements (REEs).The results showed that reactive oxygen species (ROS) production such as superoxide radical (O2-) and hydrogen peroxide (H2O2) were overproduced at higher concentrations of La,resulting in oxidatively modified proteins and shoot growth retardation.While,superoxide dismutase (SOD),catalase (CAT),ascorbate peroxidase (APX) and guaiacol peroxidase (GPX) isoenzymes were elevated to some extent to eliminate excess of ROS.HSP70 production and endopeptidase isoenzymes were also enhanced,which were involved in repairing or degradation of the oxidatively modified proteins due to La.Thus,the antioxidant isoenzymes,endoprotease isoenzymes and HSP70 worked cooperatively to alleviate the La-induced oxidative damage.The significant enhancement of CAT and APX isoenzymes and HSP70 could also be used as early bioindicators of La-polluted solution.The threshold dose range was firstly delimited as 1-2 mg/L of extraneous La,corresponding to 7.34-9.37 μg/g dry weight in the leaves.These results would be helpful to further understand the toxicological effects and possible mechanisms of REE(s) on crop seedlings. 作者: Author: WANG Ning[1]  WANG Chengrun[2]  BAO Xia[3]  LI Yueyun[2]  TIAN Liumin[2]  ZOU Huixian[4]  WANG Xiaorong[4] 作者单位: State Key Laboratory of Pollution Control and Resources Reuse, School of the Environment, Nanjing University, Nanfing 210093, China;School of Resources and Environmental Engineering, Anhui University, Hefei 230061, ChinaSchool of Life Science, Huainan Normal University, Huainan 232001, ChinaDepartment of Chemistry and Chemical Engineering, Huainan Normal University, Huainan 232001, ChinaState Key Laboratory of Pollution Control and Resources Reuse, School of the Environment, Nanjing University, Nanfing 210093, China 期 刊: 稀土学报(英文版)   ISTICEISCI Journal: Journal of Rare Earths 年,卷(期): 2011, 29(10) 分类号: X171.5 Keywords: rare earth elements (REEs)    reactive oxygen species (ROS)    antioxidant isoenzymes    HSP70    biomarker,ecological risk assessment    机标分类号: TQ1 R9 机标关键词: ions    reactive oxygen species    peroxidase    rare earth elements    superoxide radical    hydrogen peroxide    risk assessment    HSP70    results    significant    dry weight    ROS    CAT    APX    would    H2O2    SOD    REE    GPX 基金项目: the National 863 High Tech Development Plan,the National Natural Science Foundation of China,the Natural Science Foundation of Anhui Province Toxicological effects and risk assessment of lanthanum ions on leaves of Viciafaba L.seedlings[期刊论文]  稀土学报(英文版) --2011, 29(10)Viciafaba L.seedlings were hydroponically cultivated in 0-12 mg/L of extraneous lanthanum (La) for 15 d to investigate ecotoxicological effects and risk assessment of rare earth elements (REEs).The res...
  第2篇 关于环境保护的论文:Effect of refining slag containing Ce2O3 on stee
  〖预览〗Abstract:The effect of pre-melting refining slag containing different contents of Ce2O3 on the absorption and modification of Al2O3 inclusion in an Al-killed steel was investigated through the slag/steel reaction experiment at 1600 ℃.It was found that the replacement of 10 wt.%Al2O3 with Ce2O3 for 50 wt.%CaO-33 wt.%A……【全文阅读:关于环境保护的论文:Effect of refining slag containing Ce2O3 on stee
