关于空气污染的英语作文二
Air pollution is one of the major problems of the modern world.
A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too.
Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.
Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities.
They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material.
Also, engineers try to design and locate new power plants to do minimum damage to the environment.
However, it may be that we still have a long way to go before we have a "clean" world.
Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do.
People will continually find new ways to control pollution.
关于空气污染的英语作文三
Health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out.
We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air.
If there are impurities in the air, they may be absorbed by our bodies and make us ill.
We need clean air, but unfortunately, air pollution is globally present, especially in cities.
Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things.
Every year these factories pour millions upon
millions of tons of smog into air.
Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now.
Once out on the streets, they will take in fresh air and replace it with poisonous gases.
Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air.
Then, the sunlight will no longer be blackened out by smoke and soot.
关于空气污染的英语作文四
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" gradually 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 5,000 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 gascovered the town of Bhopal. Over 2,500 people were killed that night, and hundredsof thousands of people were injured. Many of the injured lost their sight.推荐阅读：关于空气污染的英语作文有关空气污染的英语作文初中有关空气污染的英语作文有关空气污染的优秀英语作文有关

空气污染 Recently, the phenomenon of air pollution has become the focus of the public concern. （分析原因）What are the reasons for the phenomenon? On my standpoint, there are several as follows. First of all, the heavy air pollution was caused by ____（原因一）. Besides, ____ （原因二）also lead to the smog in the air. In addition, ____（原因三）. In view of the seriousness of the phenomenon, effective measures should be taken. On one hand, it is high time that people all over China should ____（市民角度的应对方法）. On the other hand, the government should ____（政府角度的应对办法）. Only in these ways can we successfully solve the problem. 最近，空气污染已经成为公众关心的重点。（分析原因）空气污染的原因是什么呢？依我来看，有以下原因。 首先，严重的空气污染是因为____（原因一）。此外，____ （原因二）也会造成雾霾。再者，____（原因三）。 考虑到该现象的严重性，我们应该去采取有效的措施。一方面，全国人民是时候去____（市民角度的应对方法）。另一方面，政府应该____（政府角度的应对办法）。只有这样，我们才能成功解决这个问题。
大气环境被破坏,很难恢复,因此防治大气污染就愈发重要。那么大气污染有哪些防治措施呢？下面是整理大气污染防治措施论文的，欢迎阅读! 一雾霾概念、组成成分 1、雾霾概念 “雾”是指在水气充足、微风及大气层稳定情况下接近地面空气冷却至一定程度时空气中水气便会凝结成细微水滴悬浮于空中使地面水平能见度下降现象;“霾”是指因大量烟、尘等微粒悬浮使大气层形成浑浊状态天气现象。雾与霾主要区别在于水分含量大小，水分含量达到90%以上叫雾，水分含量低于 80%叫霾，80%—90%之间是雾和霾混合物(但主要成份是霾)。 2、雾霾组成成分 细颗粒物即 2.5是形成雾霾天气最大元凶。 2.5包括固态和液态两种形态，主要于两个一是各种污染源和发生源向空气中直接释放细颗粒物(包括烟、粉尘、扬尘、油烟、油雾和花粉等);二是部分具有化学活性气态污染物在空气中发生反应后生成细颗粒物这些前体污染物(包括二氧化硫、氮氧化物、挥发性有机物( C)、碳氢化合物和氨等)。 细颗粒物化学成份十分复杂，由于其表面积大， 2.5比和 10 更容易吸附有机物、硫酸盐、硝酸盐、铵盐、碳、各种金属化合物及病毒和细菌等微生物。由于细颗粒物长期悬浮于空气中难以沉降会对人体健康产生危害，降低空气能见度。 二雾霾天气危害 雾霾天气中 2.5粒径小比表面积大富集空气中各种化学物质以及细菌和病毒等微生物其通过呼吸系统被人体直接吸入沉积到肺泡甚至于可通过肺直接吸收而到达体内其他器官对人体产生危害。其对人体危害主要表现在呼吸系统、心血管系统、血液系统及生殖系统。 2.5能在肺泡区沉着溶入血液作用于全身不溶性部分沉积在肺部诱发或加重呼吸系统疾病; 2.5刺激肺内迷走神经造成主神经紊乱从而波及心脏并可直接到达心脏发生心肌梗塞; 2.5可引起血液系统毒性造成血栓形成还可能造成凝血异常血粘度增高导致心血管疾病发生; 2.5上附着了很多重金属及多环芳烃等有害物质易导致胎儿发育迟缓直接影响胎儿北京大学医学院教授潘小川调研结果显示 2.5超标后每增加 10微克/立方米医院心血管急诊及死亡率要增加 6%-7%高血压病急诊要增加 5%左右，除此之外 2.5所携带重金属和苯系物增大了患癌症风险。 三雾霾成因分析 雾霾发生有两个条件一是长静风、逆温极端不利气象因素使大气逆温层以下污染物难以稀释和扩散;二是较大污染物排放量即细颗粒物排放量较大在对外扩散时污染物浓度大大超过环境容量而实现空气自净，因此雾霾污染产生根本原因还是由细颗粒物排放造成。 细颗粒物污染问题复杂性远远高于传统工业污染问题是经济社会发展中深层次矛盾在环

Air pollution has caused a series of environment problems,such as the green house effect,damage to the ozone layer and acid rain. They all pose a threat to human living condition and health. Therefore,effective measures should be taken to stop air pollution. First,the government must make sure related laws are put into practice. Those who give off waste gases into the air directly without disposal would be punished. Second,people get education about what they could do to stop air pollution. Everyone using more public transportation and less private vehicle will reduce emission dramatically. Finally,let the forests play a positive rule. We need to plant more trees to purify the air instead of cutting them down. However, as a famous saying goes: easier said than done . Only the whole world works together and everyone takes action can human being succeed in stopping air pollution. 如何减少空气污染的英语作文2 Air pollution is one of the major problems of the modern world.

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 production 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 reduce the dependence on cars. In short, our humans should take responsibilities for the air pollution and have to find ways to solve this problem. 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

How do you see more and more people getting face-lifting now? 我认为现在最大的污染问题是空气污染。阴霾严重影响了我们的生活经历。尤其是在雾霾污染较严重的北京，人们因外出空气污染而不得不戴口罩，这给人们的生活带来了极大的不便。空气污染严重影响我们的健康。空气污染的主要原因是汽车尾气和工厂废气排放。鉴于这些原因，我们应该减少私家车出行，严格检查汽车尾气排放是否超标，工厂废气排放也应严格处理。只有这样，我们才能持续有效地减少空气污染，并有助于创造一个更清洁的环境。其次，改善天气条件和更多的蓝天也有助于改善城市人口的整体健康和福祉。 I think the biggest pollution problem now is air pollution. The haze has seriously affected our life experience. Especially in Beijing, where haze pollution is more serious, people have to wear masks when they go out because of air pollution, which also brings great inconvenience to people's lives. Air pollution seriously affects our health. The main causes of air pollution are automobile exhaust and factory exhaust emissions. In view of these reasons, we should reduce private car travel, strictly examine whether automobile exhaust emissions exceed the standard, and factory exhaust emissions should also be treated strictly. Only in this way can we continuously and effectively reduce air pollution and help to create a cleaner environment. Secondly, improved weather conditions and more blue sky days can also help to improve the overall health and well-being of the urban population.
关于空气质量的英语专业术语 这两天大家一定都很关注空气质量情况的播报，也许你会好奇空气质量指数到底是根据哪些污染物算出来的？各种等级的污染对我们有哪些危害？下面就来为大家科普下这些基础知识吧： 【关于空气质量的术语】 环境空气ambient air 指人群、植物、动物和建筑物所暴露的室外空气 空气质量指数air quality index (AQI) 定量描述空气质量状况的无量纲指数。 空气质量分指数individual air quality index (IAQI) 单项污染物的空气质量指数。 首要污染物primary pollutant AQI大于50时IAQI最大的空气污染物。 超标污染物non-attainment pollutant 浓度超过国家环境空气质量二级标准的污染物，即IAQI大于100的污染物。 总悬浮颗粒物total suspended particle (TSP) 指环境空气中空气动力学当量直径小于等于100μm的颗粒物。 颗粒物（粒径小于等于10μm）particulate matter (PM10) 指环境空气中空气动力学当量直径小于等于10μm的颗粒物，也称可吸入颗粒物。 颗粒物（粒径小于等于2.5μm）particulate matter (PM2.5) 指环境空气中空气动力学当量直径小于等于2.5μm的颗粒物，也称细颗粒物。 * 此前我们国家采用的空气质量标准是API (Air Pollution Index)，也就是空气污染指数；但在2012年2月后进行了修订，改为AQI，最重要的一个变化就是加入了PM2.5的监测。 【AQI基于哪些空气污染物】 The AQI level is based on the level of 6 atmospheric pollutants: ①二氧化硫：sulfur dioxide (SO2) ②二氧化氮：nitrogen dioxide (NO2)
大气污染的综合防治方法 在一个特定区域内，把大气环境看作一个整体，统一规划能源结构、工业发展、城市建设布局等，综合运用各种防治污染的技术措施，充分利用环境的自净能力，以改善大气质量。 大气污染按影响范围可分为局部污染、地区性污染、广域污染和全球性污染。地区性污染和广域污染是多种造成的，并受该地区的地形、气象、绿化面积、能源结构、工业结构、工业布局、建筑布局、交通管理、人口密度等多种自然因素和社会因素的影响。大气污染物又不可能集中起来进行统一处理，因此只靠单项治理措施解决不了区域性的大气污染问题。实践证明，只有从整个区域大气污染状况出发，统一规划并综合运用各种防治措施，才可能有效地控制大气污染。 一、污染源是防治大气污染危害的根本措施，而治理途径是多方面的，这里就其主要方法进行介绍。 1、工业合理布局，以方便于污染物的扩散和工厂之间互相利用废气，减少废气排放量。 2、实行区域集中供热，以高效率的锅炉代替分散的低矮烟囱群，以高效率的锅炉代替分散的低矮烟囱排放方式。这是城市大气污染防治的有力措施。 3、改变燃料构成。如城市工业和民用煤气、液化石油气的发展，低硫燃料和新能源（太阳能、风能、地热等）的采用。要推行采煤，以除去煤中大部分硫（主要是硫铁矿硫）。 4、减少汽车废气排放。主要是改时发动机的燃烧设计和提高油的燃烧质量，加强交通管理。 5、工业装置排放的有毒气体，要从工艺改革和回收利用方面予以控制。 6、烟囱除尘。烟气中二氧化硫控制技术分干法（以固体粉未或颗粒为吸收剂）和湿法（以液体为吸收剂）两大类。 二、那么如何才能保护好环境呢 1、减少或防止污染物的排放 ①改革能源结构，采用(如太阳能、风力、水力)和低污染能源（如天然气、酒精）。②对燃料进行预处理（如、煤的液化和气化），以减少燃烧时产生污染大气的物质。③改进燃烧装置和燃烧技术（如改革炉灶、采用沸腾炉燃烧等）以提高燃
Today,our term is going to talk about the source and control technology of air pollution.And we will talk about this topic in the following five points:Actuality of Air Pollution,Source of Air Pollution,Types of Air Pollution,Results of Air Pollution,and Control of Air Pollution. The first is Actuality of Air Pollution.Before talking about it,i want to mention the Definition of Air Pollution. Air pollution is the presence of undesirable material in air, in quantities large enough to produce harmful effects.It causes harmful effects on human health, property, aesthetics, and the global climate. We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air. If there are impurities(杂质）in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities. Along with the economical development, also caused serious air pollution. Countries also begin to pay close attention to the problem, and taken the relevant measures. Some countries have made about air pollution regulations and rules, and get substantially improved. But we are facing new

大气污染的原因及治理措施探析(新版) 摘要:人类需要发展但更需要保护环境,如何保护好我们的环境是我们共同关心的问题。 关键词:保护环境;大气污染;治理 工业和交通运输业迅速发展以及化石燃料的大量使用,将粉尘、硫氧化物、氮氧化物、碳氧化物、臭氧等物质排入大气层,使大气质量严重恶化。我国大气污染属“煤烟型”污染,全国城市空气中总悬浮微粒浓度普遍超标,平均浓度达309微克/立方米;二氧化硫浓度水平较高,部分城市污染相当严重,北方城市平均值达到83微克/立方米。我国的本溪市也曾经因烟雾弥漫而被称为“卫星上看不到的城市”;而大气中硫化物、氮氧化物业重超标导致了全国大部分地区出现酸雨,宜宾、长沙等城市酸雨出现频率大于90%,长沙降雨的平均PH值已达到3.54,酸雨的降落不仅破坏生态环境,而且加剧建筑物,
铁道、桥梁的腐蚀与破损,给工农业带来巨大的损失。而由大气污染引起的温室效应和臭氧层破坏更是直接地威胁到人类的生存。随着人类工业化程度的不断提高,“保卫地球、保护我们生成的环境”不再仅仅是一句危言耸听的口号,而是关系到我们子孙后代能否生存的刻不容缓的大事。人类需要发展但更需要保护环境,如何保护好我们的环境是我们共同关心的问题。目前,工业生产给环境带来的主要污染物为工业废气、工业废水、废渣(即工业“三废”),其中工厂每天向大气中排放大量的各种各样的工业废气对人类的健康威胁极大,尽可能将污染物排放量降低到最低限度是非常必要的。 1.大气污染原因分析 1.1大气污染的概念所谓大气污染是指人类生产、生活活动或自然界向大气排出各种污染物,其含量超过环境承载能力,使大气质量发生恶化,使人们的工作、生活、健康、设备财产以及生态环境等遭受恶劣影响和破坏。污染源可分为天然污染源和人为污染源。天然污染源是指自然界向大气排放污染物的地点或地区,如排放灰尘、二氧化硫、硫化氢等污染物的活火山、自然逸出的瓦斯气,以及发生森

2016考研英语作文必背30篇：7.大气污染 范文(七) Writing (图画提纲式议论文) 1. Describe the picture 2. Deduce the purpose of the drawer of the picture 3. Suggest your counter – measures 范文： The cartoon presents the Earth with a personified human face that seems quite unhappy. A examination of the picture immediately reveals that the source of its mood is the air pollution resulting from a huge number of automobiles spread around its surface. The cartoon, no doubt, aims at alarming humans of the heavy load we have exerted on Earth by our insatiable production and usage of automobiles. However, the majority of people merely indulge in the
celebration of the convenience brought by cars, while forgetting or simply neglecting their harmful impact on the atmosphere. Admittedly, there are various factors contributing to the current worldwide air pollution, but it is undeniable that the exhaust from automobiles is categorized as one of the major elements. I would like to make the following proposals to solve this problem: firstly, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. It should also be guaranteed that the clean energy be inexpensive so that it can be widely accepted. Besides, there should be attempts to develop possible transportation means, so that citizens can be diverted from dependence on cars. In short, it is humans' responsibility to resume clean air for Earth. 译文： 这幅漫画以拟人的方式呈现地球，它的脸显得非常不高兴。仔细观察这幅图就会发现其郁闷来自于空气污染，这是由于其表面上有着无数车辆在行驶。 毫无疑问，这幅漫画意在向人们敲响警钟，即人类永不知足的生产和使用汽车给我们的地球带来了巨大的负担。但是，大部分人却沉溺于汽车带来方便，而忘记了或者是忽略了其对大气层的负面影响。诚然，有很多因素导致了现在的全球空气污染问题，但是不能否认的是汽车废气被归为最重要的因素之一。 为了解决这个问题，我想提出以下建议：第一，我们应该运用最先进的技术从而以新能源替代化石燃料。同时，我们要确保清洁能源的价格低廉以得到大众的接受。此外，我们应该尝试发展各种交通方式，这样市民们能够摆脱对于汽车的依赖。简而言之，人类有责任来恢复地球的清洁空气。
