污染

Relationships of dose-response for cytochrome P450 contents in wheat and phenanthrene concentrations were conducted in meadow brown soil.

在此基础上，以草甸棕壤为供试土壤，菲为外源污染物，进行了菲污染暴露与P450含量的污染诱导量-效关系研究。

In this study the meadow brown soil in northeast China was picked up as the object, through the research of Sn, Hg, Sb, and Bi desorption kinetics behavior in single and combined polluted soils we explored the desorption characters and rules of Sn, Hg, Sb, and Bi in polluted soils.

文章以我国东北地区草甸棕壤作为研究对象，通过对Sn、Hg、Sb、Bi单一及复合污染土壤中Sn、Hg、Sb、Bi的解吸动力学行为的研究，探索污染土壤中重金属Sn、Hg、Sb、Bi的解吸特性与规律。

The eco-toxicity of Cu, Zn, Pb, and Cd in the single form was tested with four types of soils( red loam soils, meadow brown soils, chestnut soils, and dark brown soik) and their combined effect was determined with meadow brown soils.

测定了4种土壤(红壤、草甸棕壤、暗棕壤和栗钙土)条件下，Cu、Zn、Pb和Cd单一污染对小麦种子发芽与根伸长抑制率及其复合污染效应结果表明，同一浓度下，重金属对小麦根伸长抑制率均明显大于对种子发芽抑制率。

According to basic analytical methods of environmental quality standards for surface water in China(GB3838-2002),we used the 2002-2006 monitoring data to evaluate and characterize water quality condition of Lanzhou reach of Yellow river,based on the Nemerow index and variance analysis of the mean square deviation.

根据2002-2006年黄河兰州段水质监测数据，按照《地表水环境质量标准》GB3838-2002中Ⅲ类水质标准，确定污染物的污染程度，选用内梅罗水污染指数法，运用方差分析，对黄河兰州段水质现状进行评价分析，结果表明：(1)黄河兰州段水体的主要污染物是粪大肠菌群和总氮；(2)大量未经处理的生活污水排放是黄河兰州段的主要污染源；(3)针对黄河兰州段生活污水污染现状，提出源头治污思路。

By the same principle, it also can be indicated that TNs of all the measure sits, except a sit where a new river infloods the lake, were evaluated to be in Ⅴ level pollution. Besides, the EDEs of all the measure sits were above zero.

结果 按最大隶属度原则，大多数监测点的TP属于Ⅲ类污染级别；除新河入湖区外，其他监测点的TN均属于Ⅴ类污染级别；12个监测点的富营养化驱动指数均大于零。

Pot experiments were conducted to study the amelioration effect of meerschaum in Cd contaminated soil through artificial simulated pollution.

通过人工模拟污染、采用盆栽试验的方法，研究了海泡石对镉污染土壤的改良效果，试验结果表明：海泡石能显著促进空心菜的生长，抑制空心菜对镉的吸收，降低空心菜植株体内镉的浓度，同时，由于海泡石具有很大的表面积和较大的吸附量，可降低土壤镉的有效性。

When it comes to the control of water pollution and water quality melioration, it is important to evaluate the water quality objectively, so the aim of this paper is to evaluate total nitrogen and total phosphorus in the Chaohu Lake and to reflect the water eutrophication level in it.

目的 客观评价巢湖的氮、磷污染水平，正确反映该湖的富营养化程度，为该湖的水体污染控制及水质改善工程及同类湖泊的水质评价提供参考。

Results The contamination of arsenic and mercuric have basic controlled, but the lead and cadmium contamination seriously.

结果 我国食品中砷、汞污染状况已基本得到控制，但铅、镉的污染突出。

Current studies involving in-situ remediation of Pb-polluted soils via phosphorus-compounds are reviewed in this paper. Key factors controlling pyromorphite formation kinetic, solution optimal pH and P/Pb molarity ratio, etc. are discussed in detail. Meanwhile, prospective studies are also discussed with the view to providing further information on remediation practices and their efficiencies in dealing with Pb-polluted soils.

本文对目前国内外利用磷进行铅污染修复研究的现状进行了综述，对该研究领域中的关键问题，如磷酸铅类化合物形成的反应动力学过程控制、最佳pH、土壤中磷/铅摩尔比等进行了较深入的探讨，并展望了今后的研究方向，以期为铅污染土壤的修复及其效果评价提供参考。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
