污染

The environmental impact during production, usage and residual period of arsanilic acid was assessed in viewpoint of life cycle.

本文介绍了最常用的有机胂制剂－对氨基苯胂酸的主要用途和污染特征，从生命周期的角度识别并定量评价了其生产、使用和残留过程的环境影响，评价结果表明对氨基苯胂酸在土壤中最终残留的环境影响占其整个生命周期的99%以上，指出了常规环境影响评价在评价其环境污染上的局限性，据此提出逐步减少或禁止有机肺制剂的生产和使用、并在一些特殊的建设项目环境影响评价中推广生命周期评价的建议。

A model was proposed to describe arsenic contamination of groundwater and its influencing factors controlling the processes of arsenic migration and enrichment, which can be used for the strategies making of arsenic contamination control in arseniasis areas.

在此基础上从砷的&来源－影响因素－影响过程－高砷形成&角度提出了地下水砷污染的成因模式，对砷中毒病区的环境问题调查与地下水砷污染的防治具有重要参考价值。

The degradation of PAHs at 0.03, 0.3, and 3 mg/g soil, either added singly or as mixtures, were evaluated for their evolved CO2 in Biometer flasks. The contaminated soil was later Soxhlet extracted with hexane. The extracts were evaporated, redissolved in dimethyl sulfoxide, and subjected for Microtox assay and Medaka embryo toxicity test. The evolved CO2 from singly PAHs addition was correlated with concentration gradient.

根据结果显示，受单一PAHs污染土壤之降解量，以CO2累积量表示，两环之Naphthalene其降解量为最多，在低浓度0.03 mg PAHs/g soil时，有所谓的诱引作用产生；受混合PAHs污染土壤之降解量，以Naphthalene对於Phenanthrene的刺激作用为最大；在复育实验方面，以添加苯酸之CO2累积量为最高，单就界面活性剂而言，则以Tween 80的表现为最佳。

Result］ The study showed that the content difference of the heavy metals in soils from Blumea balsamifera planting base in Guizhou Province was more large, and the variance coefficient ranged from 13.70% to 65.79%. Results of synthetical pollution index and nemerow pollution index showed that the soils were not polluted.

结果］ 贵州省艾纳香种植基地土壤重金属含量水平差异较大，变异系数为13.70%～65.79%，均达国家土壤环境质量标准；综合污染指数与尼梅罗综合指数结果表明，调查区域内土壤未被污染。

All this, says Miss Browner, would complement Mr Obama's broader ambition to tackle global warming through a cap-and-trade scheme, whereby the government would set steadily declining annual limits on emissions, and would then auction permits to pollute up to that level.

Browner表示，所有的这些行动都有助于奥巴马实现其雄心壮志，即通过限额交易体系解决全球变暖的问题。由此，政府会要求限额污染排放量逐年下降，并对达到这一水平的污染拍卖许可证。

Firstly, the secretary-general of CAAM Specialist Committee Mr. Boshun Zhang gave the welcome address. Then the chief of the atmosphere departmentalism, pollution protection department of State Environmental Protection Administration, Mr. Hongyan Ren and other representatives from government supported institutions gave presentations on the "Automobile Pollution Control by Government" and "The Current Status China Auto Industry and Oriented Policy in the Future" as such to start the speech part of this summit.

首先，中汽协会市场贸易委员会秘书长张伯顺先生发表了致辞，随后环保部污染防治司大气处处长任洪岩等政府相关机构的代表就政府的机动车污染控制的中国汽车业现状及未来政策导向等相关话题展开了本次峰会的探讨序幕。

This paper mainly reviews the ecological functions of Ceratophyllum demersum and Hydrilla verticillata Royle, they have played the important role of in controlling water pollution at tributaries in Three Gorges Reservoir Region.

通过分析三峡库区次级河流的生态环境问题，重点分析了水体出现富营养化的几个重要方面，即营养盐和有机物污染、重金属污染和藻类的爆发等。

With the speedy development of city economy, constant rising of population and swiftness of citified process, geological issue of city environment becomes more extrusive and the problem of city water supply and need and groundwater pollution becomes more and more serious.

随着城市经济的迅速发展、人口的不断增长和城市化进程的加快，城市环境地质问题日益突出，城市水资源供需问题和地下水水质污染日益严重，水质污染导致了可用水资源量日渐减少，加剧了水资源危机和供需矛盾，直接影响工农业生产，危害生态环境和人类健康。

Pollution control of coking wastewater is a tough topic in the pollution control of industrial wastewater in China.

焦化废水的污染控制一直是我国工业废水污染控制的重大难题。

Responses of different genera of collembola to the heavy metal pollution are different. The Sinella is insensitive to Cu pollution, while Onychiurus and Isotomurus are sensitive to Cu pollution.

研究结果表明，种类数和均匀度指数都与CU的污染浓度（包括全铜含量、刊值、有效铜含量）之间的相关性达到显著或极显著水平，多样性指数与CU污染指数之间相关系数R为 A.892＊，达到了显著水平。
