跟Pollution（污染）有關(guān)的東西 求一篇有關(guān)大氣污染的論文(要好的)
空氣污染是指因人類的生產(chǎn)和生活活動使某種物質(zhì)進入大氣，使大氣的化學(xué)、物理、生物等方面的特性改變，影響人們的生活、工作，危害人體健康，影響或危害各種生物的生存，直接或間接地損害設(shè)備、建筑物等的現(xiàn)象。
空氣質(zhì)量的好壞反映了空氣污染程度，它是依據(jù)空氣中污染物濃度的高低來判斷的。空氣污染是一個復(fù)雜的現(xiàn)象，在特定時間和地點空氣污染物濃度受到許多因素影響。來自固定和流動污染源的人為污染物排放大小是影響空氣質(zhì)量的最主要因素之一，其中包括車輛、船舶、飛機的尾氣、工業(yè)企業(yè)生產(chǎn)排放、居民生活和取暖、垃圾焚燒等。城市的發(fā)展密度、地形地貌和氣象等也是影響空氣質(zhì)量的重要因素。
隨著社會經(jīng)濟的快速發(fā)展，工業(yè)化水平的提高，人類活動對環(huán)境產(chǎn)生的影響越來越大，尤其是在城市集中了大量的工廠、車輛、人口。空氣質(zhì)量由于以上原因，逐漸開始惡化，哪些地方在惡化，惡化程度如何，發(fā)展趨勢如何，專家關(guān)心它，人民關(guān)心它，政府更關(guān)心它。在新聞媒體上公開發(fā)布空氣質(zhì)量狀況，是政府為民辦實事的一項舉措，是環(huán)保工作走向與國際接軌的一項基礎(chǔ)性工作，它不僅有利于環(huán)保工作的公開透明化，也有助于促進公眾環(huán)保意識的提高和對環(huán)保工作的參與。空氣質(zhì)量根據(jù)報告時間的不同可分為：每小時報告的稱為時報；每天報告的稱為日報；每周報告的稱為周報。
空氣污染的污染物有：煙塵、總懸浮顆粒物、可吸入懸浮顆粒物（浮塵）、二氧化氮、二氧化硫、一氧化碳、臭氧、揮發(fā)性有機化合物等等。
防治大氣污染，控制污染排放是改善空氣質(zhì)量的根本措施，其主要途徑有：工業(yè)合理布局，搞好環(huán)境規(guī)劃；改變能源結(jié)構(gòu)、推廣清潔燃料、使用清潔生產(chǎn)工藝，減少污染物排放；強化節(jié)能，提高能源利用率、區(qū)域集中供暖供熱；強化環(huán)境監(jiān)督管理和老污染源的治理，實施總量控制和達標(biāo)排放；嚴(yán)格控制機動車尾氣排放等。
植物有過濾各種有毒有害大氣污染物和凈化空氣的功能，樹林尤為顯著，所以綠化造林是防治大氣污染的比較經(jīng)濟有效的措施。
水污染：
人類的活動會使大量的工業(yè)、農(nóng)業(yè)和生活廢棄物排入水中，使水受到污染。目前，全世界每年約有4200多億立方米的污水排入江河湖海，污染了5.5萬億立方米的淡水，這相當(dāng)于全球徑流總量的14%以上。
水的污染有兩類：一類是自然污染；另一類是人為污染。當(dāng)前對水體危害較大的是人為污染。水污染可根據(jù)污染雜質(zhì)的不同而主要分為化學(xué)性污染、物理性污染和生物性污染三大類。
海水污染
污水、廢渣、廢油和化學(xué)物質(zhì)源源不斷地流入大海。在許多海域，傾倒混有石油的污水是非法的，但這種事仍時有發(fā)生，而真正的石油災(zāi)難是在巨型油輪泄漏或沉沒時發(fā)生的。如今我們設(shè)法用化學(xué)品使水中石油沉淀以達到清除石油的目的。
向海洋傾倒化學(xué)和放射性廢物的作法已持續(xù)多年。容器總有一天會腐蝕掉，有害物質(zhì)便將進入海水中。我們對深層水與表層水的循環(huán)情況還了解不多，其過程或許比我們以前所想的要快。
地表水污染
五百多年以前，人們就認為飲用流經(jīng)大城市的河水是危險的，而工業(yè)化，人口增長以及新的有毒化學(xué)品，使情況愈來愈糟。
排水系統(tǒng)的鋪設(shè)和清潔劑的使用有增無減，使我們的水道和湖泊中磷酸鹽含量日益增多。這種過度營養(yǎng)導(dǎo)致藻類迅猛繁殖。消耗水中的氧，使魚類死亡，生態(tài)系統(tǒng)惡化。由于工業(yè)上不妥善處理汞化合物和其它重金屬，也造成嚴(yán)重的水污染。汞通過食物鏈的進程逐漸集中，最后對吃魚的鳥或人類造成嚴(yán)重的神經(jīng)損壞。
地下水污染
與地表水一樣，地下水也受到了污染的威脅，主要來自于地表或土壤水的下滲，農(nóng)用氮肥以及垃圾中的油、酚污染著地下水，氮肥中的硝酸鹽一旦進入地下，便轉(zhuǎn)變?yōu)閬喯跛猁}，它在人體中能夠轉(zhuǎn)變成致癌物質(zhì)。地面植被的破壞和濕地的排水減少了地表水的滲透，從而降低了潛水面。由于城市和工業(yè)的過度需要，淡水不斷被抽出作為生活和工業(yè)用水，然后作為地表污水重新排放，因而還會導(dǎo)致潛水面的進一步下降。另一方面，大量頻繁的灌溉可以增強滲透作用，使?jié)撍嬉恢鄙降乇怼６诟珊档貐^(qū)，被水滲透的土地由于異常的蒸發(fā)作用，引起地下水中鹽類的沉淀，遲早會變成不能耕作的鹽堿地。
Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms .[1] Pollution can take the form of chemical substances, or energy, such as noise, heat, or light energy. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as point source or nonpoint source pollution. The Blacksmith Institute issues annually a list of the world's worst polluted places. In the 2007 issues the ten top nominees are located in Azerbaijan, China, India, Peru, Russia, Ukraine and Zambia.
When people think about air pollution, they usually think about smog, acid rain, CFC's, and other forms of outdoor air pollution. But did you know that air pollution also can exist inside homes and other buildings? It can, and every year, the health of many people is affected by chemical substances present in the air within buildings.
Sources of air pollution refer to the various locations, activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are:
Anthropogenic sources (human activity) mostly related to burning different kinds of fuel
"Stationary Sources" include smoke stacks of power plants, manufacturing facilities (factories) and waste incinerators, as well as furnaces and other types of fuel-burning heating devices
"Mobile Sources" include motor vehicles, marine vessels, aircraft and the effect of sound etc.
Chemicals, dust and controlled burn practices in agriculture and forestry management. Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest.
Fumes from paint, hair spray, varnish, aerosol sprays and other solvents
Waste deposition in landfills, which generate methane.Methane is not toxic; however, it is highly flammable and may form explosive mixtures with air. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia or suffocation may result if the oxygen concentration is reduced to below 19.5% by displacement
Military, such as nuclear weapons, toxic gases, germ warfare and rocketry
Natural sources
Dust from natural sources, usually large areas of land with little or no vegetation.
Methane, emitted by the digestion of food by animals, for example cattle.
Radon gas from radioactive decay within the Earth's crust.Radon is a colorless, odorless, naturally occurring, radioactive noble gas that is formed from the decay of radium. It is considered to be a health hazard.Radon gas from natural sources can accumulate in buildings, especially in confined areas such as the basement and it is the second most frequent cause of lung cancer, after cigarette smoking.
Smoke and carbon monoxide from wildfires.
Volcanic activity, which produce sulfur, chlorine, and ash particulates.
Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment, into the atmosphere.
The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

Environment and Pollution
I read a piece of news recently. It says that in Japan many businessmen are selling fresh air to customers, and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so it is in the USA.
In fact, environmental pollution is a very serious problem the whole world is facing.
It is mainly caused by the waste products released from artificial substances, industrial
production and increasing consumption of goods. Bedsides, the use of chemical substances
in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.
How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.
As to us students, what we should do is to pay more attention to the environment while doing everything even small things.
