Now， the air pollution has become a big problem facing us. It can do a lot of harm to our health, so how to solve this problem effectively and quickly is quite urgent. First, I think, we should shut down some of the factories that discharge much contaminative air. Second, we should limit the amount of vehicles according to a city's carrying ability. Third, we should use more evironment-friendly materials.
現在，空氣污染成為了我們面臨的一個重大問題。空氣污染能對我們健康造成很大傷害，因此怎樣有效又快速地解決這一問題變得十分緊迫。首先，我認為，我們應該關閉一些釋放大量污染氣體的工廠。第二，我們應該根據一個城市的承載能力來限制車輛的數目。第三，我們應該使用更多有利於保護環境的材料。
④ 空氣污染對我們的生活有不良影響 英語作文
Air pollution
Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage. They can travel hundreds of miles in the wind before falling to the ground in the rain. But this "chemical rain" graally destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country's trees had been damaged by the year 1986.
Time and time again there are serious accidents that pollute the air. In 1986 there was a bad accident at a nuclear power station in Russia. A cloud of radiation crossed the whole of Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by this accident.
In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured. Many of the injured lost their sight.
⑤ 以空氣質量變差為主題的英語作文
1, the influence factors of air quality
Depending on the status of air pollution city on two factors: the diffusion ability of pollutant emissions and atmospheric. The source of pollution in relatively stable situation, the diffusion of pollutants in the atmosphere, migration, flow and transformation, and is closely related tometeorological conditions at the time, wind speed, wind direction, the diffusion of inversion layernode, precipitation and other meteorological factors play an important role in pollutant. Such aswhen precipitation occurs, or when there is wind, often and is concive to the spread of pollutants in the air; and when the mist or the wind is very small, often prone to air pollution. Therefore, to carry out the air quality forecast that we can in real time monitor the status of air pollution at the same time, according to the change of the future weather conditions, predict the future condition of the air quality, consciously rece or rece the emission of pollutants, so as to achieve frompassive defense to active prevention purposes.
Effects of 2, air quality on human health
The air pollution index of less than 50, indicated that the air quantity for a good, excellent.
The air pollution index greater than 50, less than 100, two level of good.
The air pollution index greater than 100 and less than 200, show that the pollutant concentrationsless than the limit of three levels of ambient air quality standard, the requirement for specificinstrial zone air quality index; ring this period, easy feeling crowd symptoms are mildintensifies, healthy populations appear to stimulate the symptoms, heart disease and respiratorysystem disease patients should rece physical exertion and outdoor activities;
3, the harm of smoking on health
Recognized for science and technology in the world, smoking is very harmful to health, there is a close relationship between nearly 1/4 of cancer, most respiratory diseases and cardiovascular diseases and smoking. Medical scientists prove, smokers mortality in different diseases than non-smokers, among them, 10.8 times as high as that of lung cancer, bronchitis, emphysema, 6.1 times higher, laryngeal cancer, oral cancer high 3.4 ~ 4.1 times, stomach, odenal ulcer high 2.8 times,2.6 times as high as the circulatory system diseases.
Cigarette smoke can be separated more than 3000 kinds of harmful components, mainly with tar,nicotine, carbon monoxide, nitric oxide, hydrogen cyanide and acrolein.
Carbon monoxide is the most harmful components in smoke, content is 1 ~ 5%, it combines with thehemoglobin is about 250 times greater than oxygen, so it can rece the blood oxygen carrying capacity, but also can make the artery wall edema, the formation of blisters, hinder the bloodrunning, create conditions for platelet and cholesterol deposition, resulting in atherosclerosis. Have a great effect of carbon monoxide on the development of chronic bronchitis and emphysema occursin winter, prone to "gas poisoning" is carbon monoxide poisoning. You can make people "gas poisoning death" and contains very few of carbon monoxide in the air, we can see its toxic large.
Effect of nicotine on sympathetic ganglia, parasympathetic ganglia, adrenal gland, resulting inaccelerated heart rate, blood pressure, heart disease.
Smoking harm young people is more serious, because the teenagers are in the growth stage, the body each organ system is not yet mature, more delicate, so the injured more seriously. In addition,adolescent large bronchial relatively straight, as the smoke with st particles and harmful substances from entering the respiratory tract, it is easy to march into, into each of the bronchioles and alveoli, make the bronchi and alveoli by serious violation.

1、影響空氣質量的因素
城市空氣污染狀況取決於兩個因素：污染物的排放情況和大氣的擴散能力。在污染源相對穩定的情況下，污染物在大氣中的擴散、遷移、流動和轉化，與當時的氣象條件密切相關，風向、風速、逆溫層結、降水等氣象因子對污染物的擴散起到重要作用。如當有降水出現，或有風的時候，往往有利於空氣中污染物的擴散；反之當有霧或風很小時，往往容易出現空氣污染加重。因此，開展空氣質量預報使我們能夠在實時監測空氣污染狀況的同時，根據未來氣象條件的變化，預測未來空氣質量狀況，自覺減少或降低污染物的排放，從而達到從被動防禦到主動預防的目的。
2、空氣質量對人體健康的影響
空氣污染指數小於50，說明空氣量良好，為一級優。
空氣污染指數大於50，小於100，為二級良好。
空氣污染指數大於100小於200，表明污染物濃度小於環境空氣質量三級標准限值，為特定工業區所要求的空氣質量；在這個指數期間，易感人群症狀有輕度加劇，健康人群出現刺激症狀，心臟病和呼吸系統疾病患者應減少體力消耗和戶外活動；
3、吸煙對健康的危害
世界科學界公認，吸煙對健康危害很大，將近四分之一的癌症、大部分呼吸道疾病和心血管疾病與吸煙有密切關系。醫學家證明，吸煙者在各種疾病中的死亡率比不吸煙者高，其中，肺癌高10.8倍，支氣管炎、肺氣腫高6.1倍，喉癌、口腔癌高3.4～4.1倍，胃、十二指腸潰瘍高2.8倍，循環系統疾病高2.6倍。
吸煙的煙霧中可以分離出3000多種有害成分，主要有焦油、尼古丁、一氧化碳、一氧化氮、氰化氫和丙烯醛等。
一氧化碳是最有害的成分，在煙霧中的含量為1～5％，它同血紅蛋白的結合力比氧大250倍左右，因此能減少血的帶氧能力，還能使動脈內壁水腫，形成水泡，妨礙血液運行，為血小板和膽固醇的沉積創造條件，導致動脈粥樣硬化。一氧化碳對慢性支氣管炎和肺氣腫的發生發展有很大影響，冬天易發生的「煤氣中毒」也是一氧化碳中毒。空氣中含萬分之幾的一氧化碳就可使人「煤氣中毒」而死亡，可見其毒性之大。
尼古丁作用於交感神經節、副交感神經節、腎上腺，造成心率加速、血壓升高，誘發心臟病。
吸煙對青少年的危害更為嚴重，因為青少年正處在生長發育階段，身體各器官系統還沒有成熟，比較嬌嫩，所以受毒害更為嚴重。另外，青少年的大支氣管比較直，當煙霧帶著煙塵的微粒和有害物質進入呼吸道時，很容易長驅直入，進到各個細支氣管和肺泡，使支氣管和肺泡受到比較嚴重的侵害。）

⑦ 空氣污染的英語作文怎麼寫
Air Pollution
In the past few decades, our Earth has changed a lot, but to the bad direction. Among these changes, the air pollutions resulting from a huge number of automobiles and coal-burning is almost the severest. The severe air pollution alarms humans of the heavy load we have exerted on Earth by our insatiable proction and usage of automobiles. However, with the deepening of urbanization, more cars are needed, which will make the air pollution worse. Therefore, the following actions should be taken. First, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. Second, try hard to develop possible transportation means, which are enviromental friendly. So that the citizens can rece the dependence on cars. In short, our humans should take responsibilities for the air pollution and have to find ways to solve this problem.

空氣污染
在過去的幾十年中，我們的地球發生了很大變化，但是是往壞的方向。在這些變化中，大量汽車和煤燃燒產生的空氣污染是最為嚴重的。嚴重的空氣污染警告人類，我們無休止的的生產和使用汽車給我們的地球帶來了沉重的負荷。然而，隨著城市化的加深，汽車的需求量也越大，這會導致空氣污染更嚴重。因此，我們應該採取以下行動。首先，我們應該運用最尖端的技術，以新型能源作為化石燃料的替代品。其次，努力尋找可能的環境友好型交通方式。這樣城市居民就可以減少對汽車的依賴。簡而言之，人類應該承擔空氣污染的責任，尋找解決這一問題的方法。

空氣污染
空氣污染來自工廠、電站和汽車。電站發出的煙霧中所含的化學物質造成很大的破壞。這些化學物質可以隨風飄走幾百英里，然後才隨雨水降落地面。但是這種「化學雨」逐漸摧毀森林裡的樹木，殺死湖泊中的魚。在德國，到1986年止，全國已經有過半數的樹木被摧殘。
空氣被污染的嚴重事故不時地在發生。1986年俄羅斯一座核電站發生過一起嚴重事故。一團帶有輻射的塵埃穿越了整個歐洲。據說，在俄羅斯有125 000人由於這次事故引起的疾病而死亡。
1984年印度一家工廠發生了一起嚴重事故，一團有危險的氣體籠罩著博帕爾市，當晚就有2500多人死亡，有成千上萬人受傷，受傷者中有許多人雙目失明。
