污染

The biodiversity index was ranked between 1.4 to 3.5 and increased from down stream to up stream.

综合生物指标法，八连及老梅溪为轻度污染之河川，主要污染河段以中下游为主。

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。

His delivery frequently treated these subjects in a misanthropic and nihilistic fashion, such as in his statement during the Life is Worth Losing show: I look at it this way... For centuries now, man has done everything he can to destroy, defile, and interfere with nature: clear-cutting forests, strip-mining mountains, poisoning the atmosphere, over-fishing the oceans, polluting the rivers and lakes, destroying wetlands and aquifers... so when nature strikes back, and smacks him on the head and kicks him in the nuts, I enjoy that.

他总是以一种蔑视世人、无政府主义的方式表达这些观点：我是这样看待这个问题的……几百年来，人类竭尽全力去破坏，污染和干预自然：皆伐森林，露天采矿，向空气中排放有毒气体，捕捞过度，污染江河湖海，破坏湿地和蓄水层……因此，当自然对此进行回击，给人类当头棒喝时，我会乐於当个观众。

In addition, Cd and Tl are the potential toxic elements in the supergene environment; therefore, their isotopic composition could be used to trace the source of contamination.

另外，Cd，Tl是环境污染的主要潜在元素，因此采用稳定同位素示踪还可能示踪表生环境中的污染来源。

"If you live both near a freeway and in an area of high air pollution, our results suggest that you're getting, in a sense, a doubling of the effect -- both the regional pollution levels that the children are breathing as well as the air that they are breathing, that is coming out of the tail pipe."

如果你生活在高速公路旁和高污染的地区，在某种意义上，我们的结果表明是你将承受双重危害效应，既包括地区污染对儿童呼吸系统的影响，也包括来自于尾气对其的影响。

" If you live both near a freeway and in an area of high air pollution, our results suggest that you're getting, in a sense, a doubling of the effect -- both the regional pollution levels that the children are breathing as well as the air that they are breathing , that is coming out of the tail pipe."

如果你居住公路和高空气污染地区，我们的研究结果会认为，在某种意义上，你正遭受着双重的影响----孩子们不但正呼吸当地的污染空气，而且还呼吸的排气尾管排出的废气。

If you live both near a freeway and in an area of high air pollution, our results suggest that you're getting, in a sense, a doubling of the effect -- both the regional pollution levels that the children are breathing as well as the air that they are breathing, that is coming out of the tail pipe.

如果你生活在靠近高速公路或者空气污染严重的地区，我们的研究表明你从某种角度来说在两方面受到影响：首先孩子们呼吸的空气具有很高的污染等级，其次他们呼吸的空气是从尾气管中排放出来的。

"If you live both near a freeway and in an area of higher air pollution, our results suggest that you're getting, in a sense , a doubling of the ef fect--both the regional pollution levels that the children are breathing as well as the air they breathing, that is coming out of the tail pipe."

"如果你们都住在公路附近，而且在一个空气污染更严重的地区，我们认为，从某种意义上讲，你会得到加倍的影响，呼吸着区域性的被污染的空气和汽车排气管中排除的废气。"

"If you live both near a freeway and in an area of high air pollution, our result suggests that you are getting in a sense of doubling the effect—both the regional pollution levels that the children are breathing as well as the air that they are breathing that's coming right out the tail pipe."

"如果你住在一个空气污染严重的地方而这个地方离高速公路又很近的话，我们的调查结果显视受到的危害也是双倍的—孩子呼吸的受污染的空气以及汽车排出的尾气。"

"If you live both near a freeway and in an area of high air pollution, our results suggest that you′re getting, in a sense, a doubling of the effect -- both the regional pollution levels that the children are breathing as well as the air that they are breathing, that is coming out of the tail pipe."

如果你住在一个空气污染严重的地区又离公路很近，我们的实验结果表明，你可能在某种意义上而言，受到双重影响----孩子们正在呼吸地区污染等级的空气以及汽车排出的尾气。

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。
