Air Pollution
There are many chemicals that pollute the air. In cities, the major source of pollution is carbon monoxide. Carbon monoxide is caused most of the time by gasoline-powered motor vehicles. You might have felt some of the effects of air pollution in big cities. If you have ever visited a big city, you might have noticed that your eyes burned or that you had trouble breathing. Air pollution is a problem in big cities because cars, homes, and factories give off many kinds of harmful substances, or pollutants, into the air.
Concern about air pollution has recently focused on indoor pollution. Indoor pollutants include tobacco smoke, gases from stoves, car exhaust in attached garages, and chemicals used for cleaning. Of special concern is a radioactive gas called radon. Radon comes from traces of uranium and radium that exist in practically all rocks and soil. Scientists think that every year as many as 30,000 of the 125,000 lung cancer deaths in the U. S. may be caused by radon.
Sulfur dioxide is another kind of air pollutant. It is released into the air when coal is burned. The sulfur dioxide combines with water in the air, forming sulfuric acid. This weak acid becomes part of rainwater, which falls to the earth. The acid rain harms living things and also damages buildings and other structures.
Some factories that burn coal have taken steps to cut down on acid rain. These factories have placed devices called scrubbers on their smokestacks. The scrubbers remove sulfur dioxide as it is released from burning coal.
Place a few drops of hydrochloric acid on a piece of limestone. The reaction will cause a fizzing. This is similar to the results of acid rain. In a few years, acid rain can have a dangerous effect on wildlife and eat away at buildings.
Trees are an important wildlife resource that does more than provide peace and beauty. They add oxygen and water to the air. They act as windbreaks and have a cooling effect on temperatures. Their presence slows the runoff of rainwater, and their root systems hold the soil. Together, both functions prevent harmful soil erosion.

Air Pollution
空气污染
There are many chemicals that pollute the air. 污染空气的化学品有好多种。In cities, the major source of pollution is carbon monoxide. Carbon monoxide is caused most of the time by gasoline-powered motor vehicles.在城市里,主要的污染源是一氧化碳。多数时间,一氧化碳是由用汽油做动力的机动车产生的。 You might have felt some of the effects of air pollution in big cities.在大城市里,人们可能已感觉到一些空气污染的影响。 If you have ever visited a big city, you might have noticed that your eyes burned or that you had trouble breathing. 如果你参观过一个大城市,你可能已注意到,你的眼睛发烧,或者呼吸困难。Air pollution is a problem in big cities because cars, homes, and factories give off many kinds of harmful substances, or pollutants, into the air.空气污染在大城市里是一个问题,因为汽车、家庭和工厂向空气中排放出很多种有害的物质或污染物。
Concern about air pollution has recently focused on indoor pollution. 关于空气污染的担忧最近一直集中于室内污染。Indoor pollutants include tobacco smoke, gases from stoves, car exhaust in attached garages, and chemicals used for cleaning. 室内污染物包括香烟烟雾、烤炉的气体、在附属的车库中汽车的废气。Of special concern is a radioactive gas called radon. 其中特别引起关心的是称为氡气的放射性气体。Radon comes from traces of uranium and radium that exist in practically all rocks and soil. 氡来自于实际上存在于所有石头和土壤中的痕量铀和镭。Scientists think that every year as many as 30,000 of the 125,000 lung cancer deaths in the U. S. may be caused by radon. 科学家认为,每年,美国12万5千名肺癌死亡中有多达3万人可能是由氡引起的。
Sulfur dioxide is another kind of air pollutant.二氧化硫是另一种空气污染物。 It is released into the air when coal is burned.它在煤的燃烧时释放到空气中。 The sulfur dioxide combines with water in the air, forming sulfuric acid. 二氧化硫与空气中的水结合,形成硫酸。This weak acid becomes part of rainwater, which falls to the earth. 这种弱酸变成酸雨的一部分,降落到地球上。The acid rain harms living things and also damages buildings and other structures.酸雨有害于有生命的东西,也会损伤建筑和其他结构。
Some factories that burn coal have taken steps to cut down on acid rain. These factories have placed devices called scrubbers on their smokestacks. 有些燃煤的工厂已采取步骤来减少酸雨。这些工厂已在他们的烟囱上放置了称为洗涤器的装置。The scrubbers remove sulfur dioxide as it is released from burning coal.洗涤器在二氧化硫于煤燃烧而释放出来时,除去二氧化硫。
Place a few drops of hydrochloric acid on a piece of limestone.在一块石灰石上放几滴盐酸。 The reaction will cause a fizzing.化学反应会引起嘶嘶声。 This is similar to the results of acid rain.这与酸雨的结果类似。 In a few years, acid rain can have a dangerous effect on wildlife and eat away at buildings.在少数几年中,酸雨可以对野生动植物产生有害的影响并侵蚀建筑物。
Trees are an important wildlife resource that does more than provide peace and beauty. They add oxygen and water to the air. 树木是一种主要的动植物资源,它们做出了比提供宁静和美丽更多的贡献。They act as windbreaks and have a cooling effect on temperatures.它们起到了防风物的作用,而且对气温有冷却作用。 Their presence slows the runoff of rainwater, and their root systems hold the soil. Together, both functions prevent harmful soil erosion.它们的存在减缓了酸雨的流失量,它们的树根系统则保持了土壤。加在一起,这两种功能防止了有害的土壤侵蚀。

有许多化学物质,污染空气。在城市,主要的污染源是一氧化碳。一氧化碳是造成大部分时间的汽油动力汽车。您可能感觉到的一些影响空气污染的大城市。如果您曾经访问过一个大城市,您可能已经注意到,你的眼睛被烧毁,或者您已经呼吸困难。空气污染是一个问题,因为在大城市,汽车,住房,和工厂释放出多种有害物质,或污染物,到空气中。
关注空气污染,最近集中在室内污染。室内污染物包括烟草烟雾,气体炉具,汽车废气中所附车库,和化学品用于清洁。特别令人关注的是一种放射性气体氡要求。氡来自痕迹铀和镭中存在的几乎所有岩石和土壤。科学家认为,每年有多达30000的十二点五○万肺癌死亡在美国可能造成的氡气。
二氧化硫是另一种空气污染物。它释放到空气中时,煤炭燃烧。二氧化硫与水结合在空气中,形成硫酸。这弱酸的一部分雨水,这属于地球。酸雨危害生灵,也损害建筑物及其他构筑物。
有些工厂,烧煤已采取措施,减少酸雨。这些工厂的设备称为洗涤器放置在其烟囱。洗涤器删除的二氧化硫,因为它是从燃煤。
地方几滴盐酸在一块石灰石。反应将导致嘶。这是类似的结果,酸雨。在未来几年内,酸雨会产生危险的影响,野生动植物和侵蚀建筑物。
树是一个重要的野生动物资源,它提供超过和平与美丽。他们补充氧气和水,空气。他们作为防风林和具有冷却温度的影响。他们的存在减缓径流雨水,他们的根系统举行的土壤。总之,这两种职能防止有害的土壤侵蚀。

关注空气污染最近聚焦在室内污染。室内污染物包括香烟,气体从炉、汽车尾气中使用的化学、附车库进行清洗。特别关注的是一种的放射性气体——氡。氡的痕迹,来自铀镭而存在于几乎所有岩石和土壤。科学家们认为每年多达30,000的居民死于肺癌的人在美国可能由于氡。
二氧化硫是另一种空气污染物。它被释放到空气当煤燃烧。二氧化硫结合,形成空气中的水硫酸。这种弱酸性的,下降至雨水的大地发出的渴望的声音。酸雨危害生物,也破坏建筑物和构筑物。
一些工厂烧煤已经采取措施来减少酸雨。这些工厂都放在烟囱上称为洗刷器装置。这个净化器移除二氧化碳,因为它是释放从燃烧的煤。
地方几滴在一块盐酸的石灰。他们的反应会导致fizzing。这是相似的结果。几年后,酸雨能有一个危险的影响野生动物和吞噬的建筑物。
树木是一个重要的野生动物资源,不仅为和平和美丽。他们增氧的空气和水。他们充当防风能力和温度冷却效果。他们的雨水径流减慢,它们的根部系统把土壤。双方共同作用,防止有害的水土流失。

大气污染
There是污染空气的许多化学制品。 在城市,主要污染源是一氧化碳。 一氧化碳大多时间是由靠汽油发动的机动车造成的。 您也许已经感觉某些大气污染的作用在大城市。 如果您参观了一个大城市,您也许已经注意您的眼睛烧了或您有麻烦呼吸。 大气污染是在大城市,因为汽车、家和工厂释放许多有害的物质,或者污染物的一个问题,入空气。 关于大气污染的Concern最近集中于室内污染。 室内污染物在附上车库包括从火炉的烟草烟雾、气体,汽车用于清洁的尾气和化学制品。 特殊利害关系是称氡气的放射性气体。 氡气来自存在于实际所有岩石和土壤铀和镭的踪影。 科学家认为多达30,000 125,000肺癌死亡在美国可以由氡气每年造成。
Sulfur二氧化物是另一空气污染物。 当煤炭被烧时,它被释放入空气。 二氧化硫用水在天空中结合,形成硫酸。 这微弱的酸成为一部分的雨水,落对地球。 酸雨危害生存事并且损坏大厦和其他结构。 烧煤炭的Some工厂采取步骤减少酸雨。 这些工厂在他们的烟窗安置了称洗气器的设备。 当它从灼烧的煤炭,被发布洗气器取消二氧化硫。
Place盐酸一些下落在石灰石片断的。 反应将导致一发嘶嘶声。 这类似酸雨的结果。 在几年内,酸雨可能有对野生生物的危险作用和侵蚀大厦。
Trees是资源做更多比提供和平和秀丽的重要野生生物。 他们加氧气和水到空气。 他们作为防风林并且有对温度的一个冷却效应。 他们的存在减慢雨水决赛,并且他们的根系统拿着土壤。 同时,两个作用防止有害的土壤侵蚀。
