水质污染与社会(中英对照)一

来源: 作者: 发布时间:2009-04-06  

Comprising over 70% of the Earth?s surface, water is undoubtedly the most precious natural resource that exists on our planet.  Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent: it is essential for everything on our planet to grow and prosper.  Although we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate.  In addition to innocent organisms dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes.  In order to combat water pollution, we must understand the problems and become part of the solution.

包括超过70 %的地球表面,水无疑是最宝贵的自然资源存在着我们这个星球上。没有看似宝贵的化合物组成的氢气和氧气,地球上的生命将是不存在的:它是必不可少的一切我们这个星球上的发展和繁荣。虽然我们作为人类认识到这一事实,我们无视它的污染我们的河流,湖泊和海洋。后来,我们正在缓慢但稳步地伤害我们的星球,以致生物体死亡在一个非常惊人的速度。除了无辜生物体死亡后,我们的饮用水已成为影响很大的是我们能够使用水作康乐用途。为了防治水污染,我们必须明白的问题,成为一部分解决问题的方法。

According to the American College Dictionary, pollution is defined as:  ?to make foul or unclean; dirty.?  Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water.  When it is unfit for its intended use, water is considered polluted.  Two types of water pollutants exist; point source and nonpoint source.  Point sources of pollution occur when harmful substances are emitted directly into a body of water.  The Exxon Valdez oil spill best illustrates a point source water pollution.  A nonpoint source delivers pollutants indirectly through environmental changes.  An example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off which in turn effects aquatic life.  The technology exists for point sources of pollution to be monitored and regulated, although political factors may complicate matters. Nonpoint sources are much more difficult to control.  Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes.

据美国大学词典,污染的定义是:让犯规或不洁;肮脏的。水污染时发生的水体受到不利影响,由于增加了大量的材料,以水。当不宜用于其预定用途,水被认为是污染。两种类型的水污染物存在;点源和非点源。点污染源时发生有害物质直接排放到水体。埃克森公司瓦尔迪兹溢油最好说明了点源水体污染。阿非点源污染物的间接通过提供环境变化。一个例子,这种类型的水体污染是当肥料是从外地带进流降雨的形式,决胜这反过来又影响水生生物。这项技术存在的点污染源进行监测和调控,但政治因素可能使问题复杂化。

Many causes of pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates.  In excess levels, nutrients over stimulate the growth of aquatic plants and algae.  Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters. This, in turn, proves very harmful to aquatic organisms as it affects the respiration ability or fish and other invertebrates that reside in water.Pollution is also caused when silt and other suspended solids, such as soil, washoff plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains.  Under natural conditions, lakes, rivers, and other water bodies undergo Eutrophication, an aging process that slowly fills in the water body with sediment and organic matter.  When these sediments enter various bodies of water, fish respirationbecomes impaired, plant productivity and water depth become reduced, and aquatic organisms and their environments become suffocated.  Pollution in the form of organic material enters waterways in many different forms as sewage, as leaves and grass clippings, or as runoff from livestock feedlots and pastures.  When natural bacteria and protozoan in the water break down this organic material, they begin to use up the oxygen dissolved in the water.  Many types of fish and bottom-dwelling animals cannot survive when levels of dissolved oxygen drop below two to five parts per million.  When this occurs, it kills aquatic organisms in large numbers which leads to disruptions in the food chain.

原因很多,包括污水的污染和肥料含有的营养素,如硝酸盐和磷酸盐。超过水平,养分的刺激水生植物和藻类。过快增长,这些类型的生物因此堵塞我们的水道,使用了溶解氧,因为它们分解,并阻挡光线更深水域。反过来,这证明了十分有害的水生生物,因为它影响到呼吸的能力或无脊椎动物,鱼类和其他居住在水中。污染也引起泥沙和其他悬浮固体,如土壤,袭击领域,建筑和伐木场址,城市地区,侵蚀河岸时,暴雨。在自然条件下,湖泊,河流,和其他水体进行水体富营养化,老龄化的进程,慢慢地填满了水体与沉积物和有机物。当这些沉积物进入各种水体,鱼类受损,植物生产力和水深成为减少,水生生物及其环境成为窒息而死。污染形式有机材料进入水道有许多不同的形式为污水,如树叶和草剪报,或作为牲畜饲养场径流和牧场。当自然的细菌和原生动物在水打破这一有机材料,他们开始使用的氧气溶解于水。许多类型的鱼类和底栖动物无法生存时,各级溶解氧跌破四点58分百万分之一。发生这种情况时,它造成水生生物大量导致中断食物链。

非点源更难以控制。造成污染面来源占多数污染物的小溪和湖泊。
