④ 空气污染对我们的生活有不良影响 英语作文
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 以空气质量变差为主题的英语作文
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、影响空气质量的因素
城市空气污染状况取决于两个因素：污染物的排放情况和大气的扩散能力。在污染源相对稳定的情况下，污染物在大气中的扩散、迁移、流动和转化，与当时的气象条件密切相关，风向、风速、逆温层结、降水等气象因子对污染物的扩散起到重要作用。如当有降水出现，或有风的时候，往往有利于空气中污染物的扩散；反之当有雾或风很小时，往往容易出现空气污染加重。因此，开展空气质量预报使我们能够在实时监测空气污染状况的同时，根据未来气象条件的变化，预测未来空气质量状况，自觉减少或降低污染物的排放，从而达到从被动防御到主动预防的目的。
2、空气质量对人体健康的影响
空气污染指数小于50，说明空气量良好，为一级优。
空气污染指数大于50，小于100，为二级良好。
空气污染指数大于100小于200，表明污染物浓度小于环境空气质量三级标准限值，为特定工业区所要求的空气质量；在这个指数期间，易感人群症状有轻度加剧，健康人群出现刺激症状，心脏病和呼吸系统疾病患者应减少体力消耗和户外活动；
3、吸烟对健康的危害
世界科学界公认，吸烟对健康危害很大，将近四分之一的癌症、大部分呼吸道疾病和心血管疾病与吸烟有密切关系。医学家证明，吸烟者在各种疾病中的死亡率比不吸烟者高，其中，肺癌高10.8倍，支气管炎、肺气肿高6.1倍，喉癌、口腔癌高3.4～4.1倍，胃、十二指肠溃疡高2.8倍，循环系统疾病高2.6倍。
吸烟的烟雾中可以分离出3000多种有害成分，主要有焦油、尼古丁、一氧化碳、一氧化氮、氰化氢和丙烯醛等。
一氧化碳是最有害的成分，在烟雾中的含量为1～5％，它同血红蛋白的结合力比氧大250倍左右，因此能减少血的带氧能力，还能使动脉内壁水肿，形成水泡，妨碍血液运行，为血小板和胆固醇的沉积创造条件，导致动脉粥样硬化。一氧化碳对慢性支气管炎和肺气肿的发生发展有很大影响，冬天易发生的“煤气中毒”也是一氧化碳中毒。空气中含万分之几的一氧化碳就可使人“煤气中毒”而死亡，可见其毒性之大。
尼古丁作用于交感神经节、副交感神经节、肾上腺，造成心率加速、血压升高，诱发心脏病。
吸烟对青少年的危害更为严重，因为青少年正处在生长发育阶段，身体各器官系统还没有成熟，比较娇嫩，所以受毒害更为严重。另外，青少年的大支气管比较直，当烟雾带着烟尘的微粒和有害物质进入呼吸道时，很容易长驱直入，进到各个细支气管和肺泡，使支气管和肺泡受到比较严重的侵害。）

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.

空气污染
在过去的几十年中，我们的地球发生了很大变化，但是是往坏的方向。在这些变化中，大量汽车和煤燃烧产生的空气污染是最为严重的。严重的空气污染警告人类，我们无休止的的生产和使用汽车给我们的地球带来了沉重的负荷。然而，随着城市化的加深，汽车的需求量也越大，这会导致空气污染更严重。因此，我们应该采取以下行动。首先，我们应该运用最尖端的技术，以新型能源作为化石燃料的替代品。其次，努力寻找可能的环境友好型交通方式。这样城市居民就可以减少对汽车的依赖。简而言之，人类应该承担空气污染的责任，寻找解决这一问题的方法。

空气污染
空气污染来自工厂、电站和汽车。电站发出的烟雾中所含的化学物质造成很大的破坏。这些化学物质可以随风飘走几百英里，然后才随雨水降落地面。但是这种“化学雨”逐渐摧毁森林里的树木，杀死湖泊中的鱼。在德国，到1986年止，全国已经有过半数的树木被摧残。
空气被污染的严重事故不时地在发生。1986年俄罗斯一座核电站发生过一起严重事故。一团带有辐射的尘埃穿越了整个欧洲。据说，在俄罗斯有125 000人由于这次事故引起的疾病而死亡。
1984年印度一家工厂发生了一起严重事故，一团有危险的气体笼罩着博帕尔市，当晚就有2500多人死亡，有成千上万人受伤，受伤者中有许多人双目失明。
