Under hydroponic condition, 5mg I/1 cadmium concentration was the threshold concentration, at which growth of Typha angustifolia Linn was essentially unaffected relative to the control cultures without Cd.

在水培条件下5 mg L~(-1)镉处理浓度可能是狭叶香蒲受毒害的阈值，此浓度远远超过环境中镉的含量，这表明狭叶香蒲对镉具有一定的耐性。

In a domestic zinc smelter,the "burning board" phenomenon in zinc electrodeposition resulted from the cobalt recycling to zinc system with poor cadmium solution frequently occurs,the processes and the effects for cobalt removal from poverty cadmium solution both with antimony salt and with sodium ethyl xanthate are investigated for solving the "burning board" problem.

国内某湿法锌冶炼厂由于贫镉液中的钴随贫镉液返回锌系统形成钴的闭路循环而频繁出现锌电解的钴&烧板&现象，为此研究贫镉液锑盐除钴和黄药除钴过程和效果。

Rainbow pink, Vetiver grass, and Indian mustard were used in this study to test the remediation of the Cd, Zn, and Pb-contaminated soil. The objectives of this study are to assess the effect of applying EDTA on the phytoremediation of metals-contaminated soils and to assess the interactions among three metals in multiple metals-contaminated soils. Different applying methods with same amounts of EDTA are also used in this study to assess their effect on the metal concentration in the shoot of plant and on reducing the potential risk of groundwater contamination.

本研究於受镉、锌及铅污染的坋质黏土土壤中种植五彩石竹、培地茅及印度芥菜，利用此三种植物植生复育受多种重金属污染的土壤，污染土壤的镉、锌及铅浓度分别为20、500及1，000 mg/kg，评估施用EDTA对於促进植生复育的效果，并以镉、锌及铅浓度分别为10、100及1，000 mg/kg分别配制不同重金属污染土壤，研究三种重金属间交互作用对於植物累积重金属的影响，并评估以相同的EDTA施加总量分一至四次施用对植物累积重金属及降低地下水污染的风险的效果。

A geostatistical method was put forward to analyse the spatial variability of combined heavy metal pollution in soils based on GIS. The spatial analysis showed a combined Cu and Cd pollution occurred in the research area, Cu was mainly concentrated in surface layer, but Cd had high concentrations in 0-60cm depth of soil profile. The correlation analysis revealed that the point source pollution was dominated by the pollution let-out of the smeltery.

研究首先建立了基于GIS的地统计学采样和分析方法的步骤，然后着重分析了土壤铜镉复合污染的空间变异特征和影响因素，发现研究区土壤铜镉复合污染为点源污染类型，铜在土壤中具有明显的表聚性，而镉容易迁移，在0-60cm的土层中均形成污染，同时土壤的复合污染已经在水稻籽粒中引起污染物超过食品食用标准。

Cultivars: Wuyujing No.3,a Cd tolerant cultivar and Shanyou 63,a Cd susceptible cultivar,were grown hydroponically in this study to investigate the effects of Cd applied at realistic levels on photosynthetic parameters,soluble sugar and plant growth.

以较耐镉(武育粳3号，WYJ)和镉敏感(汕优63，SY63)的2个不同耐性水稻品种为材料，采用溶液培养试验，研究了镉处理(Cd.1.0和5.0μmol/L)对水稻幼苗光合作用、可溶性糖和生长的影响。

Uniform, highly stable and well-dispersed hydrophilic CdSe-AET (2-aminoethanethiol hydrochloride) quantum dots are synthesized by changing hydrophobic TOPO to hydrophilic AET.
