Analysis result indicated that the exceptional-high concentrations of Mn was found to be the limiting factor for plant growth. The concentrations of Mn, Pb, and Cd in the ten plants and Mn-enrichmentalabilities of the ten plants were analyzed in this paper.Poa pratensts, Gnaphalinm affine, Pteris viltata L., and Phytolacca esculenta Van Houtte were proved to have good metal-enrichmental an...

结果表明，早熟禾、鼠麴草、蕨、和商陆对Mn有较强富集能力，同时也是Mn的耐性植物；早熟禾、鼠麴草以及蕨对Pb的吸收和富集能力较强；小飞蓬、早熟禾和麴草对Cd的富集能力较强；但是各种植物对这 3种重金属的富集能力均未达到超富集植物的要求，进一步的改良栽培实验仍在研究中

大厂矿区尾砂成分相当复杂，含有多种对植物生长有害的重金属元素，且缺乏植物生长所必须的营养物质，纯尾砂环境中植物的自然定居十分困难。

Linear regression analysis demonstrated that GI, whichrepresented phytotoxic behavior to the plants, could be poorly predicted by the sum of mobilemetal fractions (exchangeable +carbonate +reducible iron and manganese+ organic matter bound,EXCH+CAR+FeMnOX+OMB), i.e., Cu (EXCH+CAR+FeMnOX+OMB) in SS, Pb (EXCH+CAR+FeMnOX+OMB) in SM.

在用重金属有效性形态之和(交换态+碳酸盐结合态+铁锰氧化态+有机结合态，EXCH+CAR+FeMnOX+OMB)回归青菜与黑麦草发芽指数的方程中，只有污泥堆肥中的Cu和猪粪堆肥中的Pb与青菜及黑麦草的GI线性相关。

A survey on the crops grown on the restored manganese mine lands in Pingle and Lipu of Guangxi was conducted, and the heavy metal concentration s in the edible parts of the crops were analyzed.

对广西平乐、荔浦两锰矿恢复区种植的食用农作物进行了调查和重金属含量分析。

Extensive soil sampling of the crop-reclaimed Mn mine wastelands was conducted in the six typical manganese minelands (Bayi, Lipu, Pingle, Quanzhou, Bansu and Xialei) in Guangxi, China. In the six reclaimed minesoils, the heavy metal concentrations were Pb 41.63~348.31 mgkg^(-1), Cr 48.12~287.29 mgkg^(-1), Zn 47.38~269.92 mgkg^(-1), Cu 12.71~138.03 mgkg^(-1), Cd 0.73~46.50 mgkg^(-1), and Mn 676.7~41996.4 mgkg^(-1) respectively.

对广西八一、荔浦、平乐、全州、板苏和下雷6个锰矿食用农作物恢复区土壤重金属进行含量测定，结果表明，土壤各元素含量为：Pb 41.63~348.31 mgkg^(-1)、Cr 48.12~287.29 mgkg^(-1)、Zn 47.38~269.92 mgkg^(-1)、Cu 12.71~138.03 mgkg^(-1)、Cd 0.73~46.50 mgkg^(-1)、Mn 676.7~41996.4 mgkg^(-1)。

In laboratory conditions, using the traditional microbiological culture, a different concentration on the source of heavy metals Cd6+ stress the Pistia stratiotes root of the microbial flora and major groups of physiological effects.

在实验室条件下，用传统的微生物培养法，研究了不同浓度的外源重金属 Cd6+对大薸根系微生物区系及主要生理类群的影响。

To understand the effect of heavy metals on Portunus trituberculatus, larvae were exposed to varying concentrations of Cu, Pb, Cd and Hg.

为了解海洋重金属污染对三疣梭子蟹的危害，进行了Cu、Pb、Cd、Hg对三疣梭子蟹幼体影响的试验。

Pteris nervosa L. were discovered and confirmed as another arsenic hyperaccumulator in field investigation, could accumulate arsenic up to 1000mg/kg in pinnate in field. P. vittata L. and P. nervosa L.

通过野外调查，发现和证实了大叶井口边草是一种As的超富集植物，并发现蜈蚣草和大叶井口边草对多种重金属都具有很高的耐性。

The basic structural parameters of pitch2based spherical activated carbon were characterized ,such as specific surface area by BET model , total pore volume , micropore and mesopore volume , sphericity , hardness and content of heavy metal ions . Its adsorption capacity to creatinine and vitamin B 12 , which are typical small and medium toxic molecules in blood , were measured. Hemolysis ratio , number of particles released , pyrexic source and germ count in a man2made kidney made of PSAC were checked .

表征了沥青基球状活性炭的基本结构参数(如比表面积、孔容量、球形度、强度、重金属含量等)，测定了其对血液中典型中、小毒性分子的吸附性能(肌酐和VB12 )和溶血反应率，分析了以沥青基球状活性炭为吸附剂的人工炭肾的微粒释放量、热源和细菌含量，并进行临床试验。
