Pollution of environment
These days we often hear that our living conditions are getting more and more serious because of the destruction of our environment. It is common that many trees and animals are near extinction, and the all-important food chain has been destroyed. Why does such circumstance occur in spite of social protects?
For one thing, the population of the world is increasing so rapidly that the world has been so crowded. For another, the overuse of natural resources has influenced the balance of natural ecology. What’s more, since the industrial revolution, it is natural that a great number of factories have been springing up like mushrooms. The smoke and harmful chemicals released from factories also pollute the environment.
To solve the problem is not easy at all, but is worth. We should do something such as planting more trees, equipping cars with pollution-control devices and learning to recycling natural resources to improve the present situation. I do believe everything will be better in the future.

《建筑类专业英语-给水排水环境与保护(第二册)第十三章》
第十三单元Quantitative discussions of air pollution are hampered by the lack of a clear definition for“clean air”．Most scientists assume‘air’to be a mixture of the gases listed in Table 1．If this is clean air, then any constituent of air can be called a pollutant．However，one never finds such“clean air”in nature。It may thus be more appropriate to define air pollutants as those substances which exist in such concentrations as to cause an unwanted effect. .These pollutants can be natural (such as smoke from forest fires) or man-made (such as automobile exhaust)and can be in the form of gases or particulates(liquid or solid particles larger than 1 micron). 关于对空气污染的定量研讨．由于缺乏聪“洁净空气”的明确定义而有所困难。大多数科学家认为“空气”应是表l中所列气体婚混和物。如果这种空气就是洁净空气，那么奈气中的任何成分都可以称为污染物。然而，大自然中永远找不到如此的“洁净空气”。因此将那些以足以产生有害影响的浓度而存在的物质定义为空气污染物也许比较恰当。这污染可能来自自然界(如森林火灾的烟雾)或者来自人类自己(如汽车废气)。它们可能是气态，或是颗粒状(大予一微米的液态或固态微粒)。In the context of air pollution control, ,gaseous pollutants include substances that are gasses at normal temperature and pressure as well as vapors of substances that are liquid or solid at normal temperature and pressure. Among the gaseous pollutants of great importance in terms of present knowledge are carbon monoxide, hydrocarbons, hydrogen sulfide, nitrogen oxides, ozone and other oxidants and sulfur oxides. Carbon dioxide should be added to this list because of its potential effect on climate. 在空气泻染的控制中．气态污染包括常温常压状态的气体物质，也包括常温常压下呈液态或固态物质的蒸气。目前所知的最主要的气态污染物有一氧化碳、碳氢化合物、硫化氡、氮氧化物、臭氧和其他氧化剂及氧化硫。二氧化碳因其对气候的潜在影响也是主要的气态污染物。Particulate pollutants are classified as follows：dust，fume，mist，smoke and spray．Particulate pollutants found in the atmosphere or emitted from a source can be chemically complex，consisting of a variety of metallic and nonmetallic constituents．颗粒状污染物可分为：尘埃、烟尘、烟雾、烟及雾状物。大气中和来自污染源的颗粒状污染物的化学成分复杂．可能含有许多金属和非金属成分.Many of the pollutants of concern are formed and emitted through natural processes．For example，naturally—occurring particulates include pollen grains，fungus spores，salt spray, smoke particles from forest fires，and dust from volcanic eruptions．Gaseous pollutants from natural sources include carbon monoxide as a b
reakdown product in the degradation of hemoglobin，hydrocarbons in the form of terpenes from pine trees, hydrogen sulfide resulting from the breakdown of cysteine and other sulfur-containing amino acids by bacterial action, nitrogen oxides, and methane. 许多引起人们关注的污染物是大自然自身产生和散发的。例如：自然界固有的微粒就包括花粉粒，霉菌孢子·盐雾，森林火灾所散发的烟尘以及火山爆发时喷出的火山灰。来臼天然污染源的气态污染物有血红蛋白降解过程中产生的一氧化碳，松树的萜烯烃，由于：细菌作用而导致半胱氨酸及其他含硫的氨基酸分解时生成的硫化氢．氮氧化物及甲烷。Man—made sources of pollutants can be conveniently classified as stationary combustion, transportation, industrial process．and solid waste disposal sources．The principal pollutant emissions from stationary combustion processes are particulate pollutants，as fly ash and smoke．and sulfur and nitrogen oxides．Sulfur oxide emissions are, of course, a function of the amount of sulfur present in the fuel．Thus．combustion of coal and oil，both of which contain appreciable amounts of sulfur, yields significant quantities of sulfur oxide．Nitrogen oxides are formed by the thermal fixation of atmospheric nitrogen in high temperature processes．Accordingly，almost any combustion operation will produce nitrioxide (NO)which subsequently undergoes oxidation to nitrogen dioxide(N02)．Other pollutants of interest from combustion processes are organic acids , aldehydes，ammonia and carbon monoxide．The amount of carbon monoxide emitted relates to the efficiency of the combustion operation．i.e．, a more efficient combustion operation will oxidize more of the carbon present to carbon dioxide, reducing the amount of carbon monoxide emitted．Of the fuels used in stationary combustion, natural gas is perhaps the most desirable from the view of air pollution．Natural gas contains practically no sulfur，and particulate emissions are almost nil．人为造成的污染源可简单地归为以下几种·固定燃烧炉，运输工具，工业生产及固体发物处置污染源。固定燃烧过程中主要释放出的污染物是颗粒状污染物。如飞灰和烟尘以埂硫和氮的氧化物。当然-二氧化硫的排放量是由燃料中的含硫量而决定的。煤和油的燃接着继续氧化成二氧化氮(N()：)。由燃烧雨产生的其他重要污染物有：有机酸、醛类、氨硬一氧化碳。 一氧化碳的排放量与燃烧过程的效率有关，即：较高效率的燃烧过程能氧化较多的碳．产生二氧化碳而降低一氧化碳的排放量。从空气污染的角度来看．所有用于固定燃烧的燃料中，天然气或许是最理想的燃料。实际上。天然气不含硫，并且颗粒状污染物的排放量几乎是零。Transportation sources, particularly automobiles us
ing the internal combustion engine，constitute a major source 0f air pollution．Particulate emissions from the automobile include smoke and lead particles．the latter usually as halogenated compounds．Smoke emissions as in any other combustion operation are due to the incomplete combustion of carbonaceous material．On the other hand, lead emissions relate directly to the addition of tetraethyl lead to the fuel as an antiknock compound．Gaseous pollutants from transportation sources include carbon monoxide，nitrogen oxides．and hydrocarbons．Hydrocarbon emissions result from incomplete combustion and evaporation from the crankcase，carburetor, and gasoline tank.。运输工具污染源。尤其是用内燃机的汽车，是最主要的空气污染源。汽车的颗粒排放物有烟尘和铅尘·而后者都通常是卤化合物。正如其他任何一一种燃烧过程一样．烟尘应归咎于含碳物的不完全燃烧。另一方面，所徘放出的铅直接与在燃料中加入的抗爆剂四乙铅有关。运输工具所排放的气态污染物有二二氧化碳、氮氧化物和碳氢化合物。燃料在曲轴箱．汽化器及汽油箱望的不完全燃烧和气化，导致了碳氢化合物的排放.Significant progress has been made in controlling pollution from automobiles. Exhaust has been cleaned by better than 90％over 1963 models，and further improvement will be evident over the next 5 years．人类在控制汽车污染方面已作出了重大的成就。目前排放废气的洁净度较1963年模式提高了百分之九一卜多，在今后的五年内显然还会有更大的改进。Pollution emissions from industrial processes reflect the ingenuity of modern industrial technology. Thus nearly every imaginable form of pollutant is emitted in some quantity by some industrial operation．由工业生产所排放的污染物反映了现代工业技术的创新。因此．工业生产过程中排放一定量的几乎每一种可以想到的污染物。Solid waste disposal is often a major source of urban air pollution．Although solid waste disposal operations need not be a major source of air pollutants， many communities still permit backyard burning and／or disposal of solid waste by open burning dumps．These techniques，which attempt to reduce the volume of waste，produce instead a variety of difficult—to—control pollutants. Among these are undesirable odors．carbon monoxide, all amounts of nitrogen oxides，organic acids，hydrocarbons，aldehydes., and great quantities of smoke. (Both backyard burning and open burning dumps are prime examples of inefficient combustion.) 固体废物处置常常是城市主要的空气污染源。尽管固体废物处置过程并不一定是主要的污染源，但许多社区仍然允许在庭院或露天焚烧垃圾作为固体废物处置的办法。这些试图减少废物的方法却制造出种种难以控制的污染物。这些污染物足难
闻的气味．一一氧化碳、少量的氮氧化物，有机酸、碳氢化合物．醛类以及大量的烟尘。(在庭院和露天焚烧垃圾都是无效燃烧最典型的例子。)
