不污染的

With this precaution, there was no possibility of contamination and there is no record that any occurred.

在这种预防措施下，不会有发生污染的可能，也没有污染出现的记录。

In order to protect our environment from being polluted, I will do some publicity with my classmates to explain the harmfulness of pollution.

为了保护我们的环境不被污染，我将和我的同学做一些关于污染的宣传。

The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。

With the aggravation of organic pollution of the drinking water source and the improvement of the water-quality standards, the conventional treatment craft of drinking water used in most of water plants in China can't remove the organic pollutant effectively to satisfy people's demand in the water quality. Consequently, permanganate preoxidation technic and mineral materials are combined with coagulation to removing the organic pollutant of drinking water further, so that to solve the increasing contradiction between the aggravation of organic pollution of the drinking water source and the striction of the water-quality standards.

随着饮用水源有机污染的日益加重以及饮用水水质标准的不断提高，我国大多数水厂所采用的传统处理工艺不能有效地去除有机污染物，从而对饮用水水质产生一定的影响，因此，引入高锰酸钾预氧化技术和矿物吸附材料，从而强化去除饮用水中的有机污染物，以解决水源有机污染日益严重与饮用水水质标准日趋严格之间的矛盾。

To avoid the fatigue of finger work, it has a special design of suitable frapping inside.

Despite the inevitable contamination from GE alfalfa, the EIS disavows this harm and places the entire burden for preventing contamination on non-GE farmers, with no protections for food producers, consumers and exporters.

尽管基因工程苜蓿有不可避免的污染，EIS不承认这种伤害，把全部****这种污染的负担强加到非基因工程的作物的农民身上，并对食品的生产者，消费者和出口商不采取任何保护。

尽管基因工程苜蓿有不可避免的污染，EIS不承认这种伤害，把全部抵制这种污染的负担强加到非基因工程的作物的农民身上，并对食品的生产者，消费者和出口商不采取任何保护。

Despitethe inevitable contamination from ge alfalfa, the eis disavows thisharm and places the entire burden for preventing contamination onnon-ge farmers, with no protections for food producers, consumersand exporters."if roundup ready alfalfa is permitted to be soldcommercially, the ripple effect would wipe out many organic andnon-ge businesses, from organic seed and forage growers to organicdairy farmers and retailers," said liana hoodes, director, nationalorganic coalition.

尽管基因工程苜蓿有不可避免的污染，eis不承认这种伤害，把全部抵制这种污染的负担强加到非基因工程的作物的农民身上，并对食品的生产者，消费者和出口商不采取任何保护。lianahoodes（director， national organiccoalition）说&如果草甘磷苜蓿允许出售，产生的连锁反应将消灭多种有机物和非基因工程产业，从有机种子，饲料加工到有机奶农及其零售商，无一幸免。&

"Unfortunately, I was misquoted and taken out of context, and it's unfair to characterize the pollution coming just from China and India," said Johnson, adding that other countries including the Republic of Korea and the United States all contributed to global air pollution.

&不幸的是，我的话被误用并断章取义了，而说这些污染仅仅来源于中国和印度也是不公平的& Johnson 说。他还说其他国家包括韩国和美国也都对全球空气污染负有责任。

Again, take my hometown for example, those local officials also live in the same place, drinking polluted water and breathing polluted air. Don't they feel uncomfortable?

同样以我的家乡为例，那些官员们同样生活在上述环境中，喝着污染的水，呼吸着污染的空气，他们就不难受吗？
