关于雾霾的危害英语作文2

oday, seeing the news broadcast on TV that there is "haze" weather in many cities such as Beijing, pedestrians are wearing masks to go out So he asked his father curiously, "is haze an infectious disease?" My father said, "you can check the Internet yourself. Which one is more detailed?" So, I turn on the computer, "haze" just know it was a kind of harm.

"Haze" was originally caused by low air pressure, non circulation, many particles floating, a lot of dust floating on the ground and automobile exhaust, factory production or heating at home. "Haze" particles will have a serious impact on the human respiratory tract, such as coughing, expectoration, asthma, tracheitis, etc., and even more serious will lead to death. How terrible! I hurriedly went on to see what I could do to deal with it. On the Internet, I said that I would try not to go out in the morning. I would wear a mask and eat more lung clearing and lung moistening food, such as fat sea tea, stewed red pear with scallops and so on.

Such a big "pest" was originally caused by the unlimited exploitation and destruction of the environment by human beings themselves. How I wish our living environment was blue sky and clear water, picturesque in four seasons! Please return the earth green!

今天，在电视里看到新闻播报北京等许多城市出现“雾霾”天气，行人纷纷都戴口罩出门……于是好奇的问爸爸：“雾霾是传染病吗？”爸爸说：“你可以自己上网查呀，哪样更详细的知道。”于是，我打开电脑，百度“雾霾”才知道它原来也是一种危害。

“雾霾”原来是由于空气中气压低，不流通，许多颗粒飘浮，地面上许多飘扬起来灰尘和汽车的尾气，工厂里生产或是家里取暖产生烟雾之类共同造成的。“雾霾”里的.颗粒会对人体的呼吸道产生严重影响，比如咳嗽、咳痰、气喘、气管炎等等，再严重的会导致死亡。多么可怕呀！我连忙接着往下看看有什么办法对付，网上介绍说，早晨尽量不出门，出门要戴口罩，多吃清肺润肺的食物，比如：胖大海茶饮、川贝炖红梨之类的。

如此大的“害虫”原来也是人类自身无限制的开采与破坏环境造成，多么希望我们生活的环境是蓝天碧水，四季如画呀！请还地球一片绿吧！

关于雾霾的危害英语作文3

When it comes to haze, I believe many people hate it to the bone and sigh when talking about it. No, just a few sunny days, Monday morning gave us a big "surprise".

In the morning, as soon as I stepped out of the door, I was stunned by the scene in front of me: the sky seemed to be covered by a gray cloth, and the pedestrians, roadside plants and cars on the road were also dyed gray. Everything is covered with a layer of ash. Walking on the street, the visibility is less than 100 meters. Under the influence of haze, the original clear scene becomes extremely blurred. Even the bright colors of the traffic lights seem to be in a trance.

At school, the situation has not changed, and low temperature is of no use. The red flag is flying in the middle of the air. The soft and beautiful movements are slightly slow due to the influence of the dust around. Because in haze days, many small particles will be inhaled, and the oxygen content in the air will be reduced, which is not suitable for sports, so the physical education class in the morning has also been cancelled. I dont know if I should be happy or worried.

Haze days, its really annoying!

说起雾霾，相信不少人都对它恨之入骨，谈起时也是唉声叹气。这不，刚有了几天晴天，周一早上就给我们了一个大“惊喜”。

早上，刚踏出门口，眼前的一幕就让我惊呆了：天空好像被一块灰蒙蒙的布给笼罩了起来，路上的行人、路边的植物、汽车，也被染成了灰色。所有的一切都覆上了一层灰。走在街上，能见度不足百米。原本清晰的景象在雾霾的影响下，变得万分模糊。就连红绿灯鲜艳的颜色看起来都有些恍惚。

到了学校，情况并没有变化，低温也没有丝毫的用处。红旗在半空中飘扬，柔美的动作因为周围灰尘的影响，出现了细微的迟缓。因为在雾霾天里运动，会吸入许多小颗粒，空气中的含氧量也会降低，极不适宜运动，所以上午的体育课也被取消了。真不知道是该喜还是该忧。

雾霾天，还真是讨厌！

篇一：雾霾带来的危害

Haze is air pollution in which is mixed up with dust, smoke and other dry particles ,and it obscure the clarity of the sky and interacts with the natural environment.

This kind of air pollutant come from a variety of natural and manmade sources. Natural sources can include windblown dust, and soot from wildfires. Manmade sources can include motor vehicles, and industrial fuel burning, and manufacturing operations. The one of the main cause that touches off haze is manufacturing operations. Many factories were over measure produced the smog that had over the standard and the smog seriously influence the air become air pollution.

The components that make up haze may have negative effect on peoples health especially that of the children and the elderly. Also not excluded are those who have certain diseases such as asthma, allergy, and pneumonia and lung disease. Workers working in the open air have a high risk in their health. One of effective solutions to help eliminate haze is to make some chemistry changes during the manufacturing process,so it could reduce harmful emissions which are produced by manufacturing operations. Caring for the environment, it should be started by each person.

雾霾是一种空气污染现象，其中夹杂了灰尘，烟雾和其他的干颗粒，它掩盖了天空的清晰度和与自然环境相互作用。

这种空气污染物来自各种自然和人为来源，天然来源可以包括扬尘和野火烟尘，人为源包括汽车和工业燃料燃烧和生产业务。引起阴霾的一个的主要原因是制造业务，很多工厂在生产产品时，都有超标准和严重影响空气并成为空气污染的`烟雾。

雾霾的成分可能对人的健康造成负面影响尤其是儿童和老人，也不能排除那些拥有某些疾病，如哮喘，过敏，肺炎和肺疾病的人。工人在露天工作时，他们的健康有很高的危害。

一个消除灰霾有效的解决方案，是在制造过程中进行一些化学步骤，它可以减少由制造业务产生的有害气体排放。爱护环境，应该由每个人做起。

篇二：雾霾带来的危害

Since the development of the technology, the society gets modernized, people make use of the high technology to pursue more profit. Though the government has noticed the problem that people do to the environment, they still can’t prevent negative result that the polluted environment brings.

Many years ago, the most prominent problem of the polluted environment is that the river and the water were changed their color, some fish even died for the polluted river. Now the situation becomes ever worse, lately, in the big city, like Beijing and Shanghai, people are annoyed by the bad weather. It is not the rainy day, but the haze around the sky, there is no way for people to run away for it. The haze contains toxic elements, people breathe it and hurt their bodies.

The haze problem is the result of people’s pursuit for the profit, what people did to the environment now has been paid back by the environment. Now people have realized the revenge from the nature is so huge, protecting the environment is the main task. No matter how bad the environment is, people still need to do something to fix their mistake.

【参考译文】

打从科技的发展，社会已经变得现代化，人们充分利用高科技来追求更多的利润。虽然政府已经注意到了人们对环境所做的事情这个问题，但是他们仍然不能阻止被污染环境的所带来的后果。

很多年前，环境污染所带来的最突出问题时河流和水的颜色被改变，一些鱼甚至死于被污染的河流。现在这样的情形变得更加的糟糕，最近，在大城市，比如北京和上海，人们受困于糟糕的天气。并不是因为雨天，而是因为雾霾包围天空，人们无处可逃。雾霾中含有有毒的元素，人们呼吸着雾霾，损害着他们的身体。

雾霾问题是人们追求利润而造成的，人们曾经对环境所做的现在已经得到了报复。现在人们已经意识到了大自然的报复是多么的大，保护环境是主要的任务。无论环境变得多坏，人们仍然要去做一些事情来弥补自己的错误。

雾霾的危害英语作文3

一、对人体产生的危害

1、伤肺。

霾的组成成分非常复杂,包括数百种大气化学颗粒物质。对于支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸系统疾病患者，雾霾天气可使病情急性发作或急性加重。如果长期处于这种环境还会诱发肺癌。

2、伤心脏及血管。

雾霾天对人体心脑血管疾病的.影响也很严重，会阻碍正常的血液循环，导致心血管病、高血压、冠心病、脑溢血，可能诱发心绞痛、心肌梗塞、心力衰竭等，使慢性支气管炎出现肺源性心脏病等。

浓雾天气压（气温）比较低，人会产生一种烦躁的感觉，血压自然会有所增高。一些高血压、冠心病患者从温暖的室内突然走到寒冷的室外，血管热胀冷缩，也可使血压升高，导致中风、心肌梗死的发生。

3、雾霾天气还可导致近地层紫外线的减弱，使空气中的传染性病菌的活性增强，传染病增多。

4、不利于儿童成长。由于雾天日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收大大减少，严重的会引起婴儿佝偻病、儿童生长减慢。

5、影响心理健康。

专家指出，持续大雾天对人的心理和身体都有影响，从心理上说，大雾天会给人造成沉闷、压抑的感受，会刺激或者加剧心理抑郁的状态。此外，由于雾天光线较弱及导致的低气压，有些人在雾天会产生精神懒散、情绪低落的现象。

6、影响生殖能力。

有研究表明，长期暴露于高浓度污染的空气中的人群，其精子在体外受精时的成功率可能会降低。研究人员还发现了有毒空气和男性生育能力下降之间的关联 。雾霾天气现象会给气候、环境、健康、经济等方面造成显著的负面影响。

7、易引发老年痴呆症。

2017年2月6日报道，根据一项英国兰卡斯特大学的Maher及其团队发表在《美国国家科学院院刊》上的最新研究发现：“雾霾等空气污染，损伤的不仅是我们的肺，还有我们的大脑。”

二、对交通和生活环境造成的危害

1、影响交通安全。

雾霾天气时，由于空气质量差，能见度低，容易引起交通阻塞，发生交通事故。在日常行车行走时更应该多观察路况，以免发生危险。

2、影响生活环境。

雾霾天气对公路、铁路、航空、航运、供电系统、农作物生长等均产生重要影响。雾、霾会造成空气质量下降，影响生态环境，给人体健康带来较大危害。

雾霾的前因,现象,对策的英文解释

雾霾的源头多种多样，比如汽车尾气、工业排放、建筑扬尘、垃圾焚烧，甚至火山喷发等等，雾霾天气通常是多种污染源混合作用形成的。但各地区的雾霾天气中，不同污染源的作用程度各有差异。

A variety of sources haze diversity, such as automobile exhaust, industrial emissions, construction dust, waste incineration, and even the eruption of a volcano and so on, haze weather is usually formedof various sources of pollution mixing effect. But in the regions of the haze weather, extent of different pollution sources are different.

雾霾天气自古有之，刀耕火种和火山喷发等人类活动或自然现象都可能导致雾霾天气。不过在人类进入化石燃料时代后，雾霾天气才真正威胁到人类的生存环境和身体健康。急剧的工业化和城市化导致能源迅猛消耗、人口高度聚集、生态环境破坏，都为雾霾天气的形成埋下伏笔。

The haze weather have since ancient times, slash-and-burn cultivation and volcano eruption and other human activities or natural phenomena could lead to haze weather. But in the mankind enters thefossil fuel era, haze weather is really the threat to human survival environment and health. Rapidindustrialization and the city led to the rapid consumption of energy, high population density, the destruction of the ecological environment, are buried the foreshadowing for the formation of hazeweather.

雾霾的形成既有“源头”，也有“帮凶”，这就是不利于污染物扩散的气象条件，一旦污染物在长期处于静态的气象条件下积聚，就容易形成雾霾天气。雾霾形成有三个要素：

Haze has formed "the source", also have "accomplice", meteorological condition and this is not conducive to the spread of pollutants, once pollutants in meteorological conditions under long-termstatic accumulation, it is easy to form haze weather. Haze formation has three elements:

一是生成颗粒性扬尘的物理基源。我国有世界上最大的黄土高原地区，其土壤质地最易生成颗粒性扬尘微粒。

One is the physical base source to generate particles of dust. China has the world's largest loess plateau region, the soil texture is most easily generate particles of dust particles.

二是运动差造成扬尘。例如，道路中间花圃和街道马路牙子的泥土下雨或泼水后若有泥浆流到路上，一小时干涸后，被车轮一旋就会造成大量扬尘，即使这些颗粒性物质落回地面，也会因汽车不断驶过，被再次甩到城市上空。

The two is the movement caused by poor dust. For example, the middle of the road garden and streetcurb soil splashing rain or if mud flow into the road, an hour after being dry, a rotary wheel will cause a large number of dust, even if these particles fall back to the ground, will continue to pass through for the car, was again thrown into the city over the city.

三是扬尘基源和运动差过程集聚在一定空间范围内，颗粒最终与水分子结核集聚成霾。目前来看，在我国黄土平高原地区350多座城市中，雾霾构造三要素存量相当丰裕。

Three is the dust based source and movement differential process gather in a certain space range,particles and water molecules into the final tuberculosis agglomeration haze. At present, in China'sloess plateau area of more than 350 flat in the city, the three elements of stock pretty much hazestructure.美国进口普卫欣天 猫有效防雾霾

、雾霾天气少开窗。出门在外一定要戴口罩，平常多饮水，可多泡饮菊杞茶这类中医茶饮，预防疾病，多食用水果，从外回家后要深度清洁皮肤和头发，此外喜爱晨练以及买菜遛弯的老年人要注意减少出门，因为雾霾对老年人的身体危害极大。

1, fog haze weather windows. Go out in the outside must wear masks, water more at ordinary times,can be multi bubble drink chrysanthemum tea wolfberry tea of this kind of traditional Chinese medicine, disease prevention, fruit consumption, from home to deep clean the skin and hair, in addition to favorite morning exercises and buy food for his walk old people should pay attention to reduce go out, because the haze of the elderly the body great harm.

2、外出戴口罩

2, to go out wearing a mask

3、多喝茶

3, more tea

4、适量补充维生素D

4, the amount of vitamin D

5、饮食清淡多喝水

5, light diet drink plenty of water

6、多吃蔬菜

6, eat more vegetables

7、在雾霾天气尽量减少出门[6]

7, in the haze weather minimize out [6]

8、开车注意车速

8, pay attention to the speed drive

9、出门时，做个自我防护，佩戴专门防霾的PM2.5口罩、防霾鼻罩，过滤PM2.5，随时随地呼吸新鲜空气。

9, when you go out, do a self protective, wear special anti PM2.5, anti haze haze mask nose cover,filter the PM2.5 whenever and wherever possible, to breathe the fresh air.

10、避免雾天锻炼。可以改在太阳出来后再晨练。也可以改为室内锻炼。

Exercise 10, to avoid fog. Can be changed when the sun comes out to do morning exercises. Can also be replaced by exercising indoors.

11、患者坚持服药。呼吸病患者和心脑血管病患者在雾天更要坚持按时服药

11, patient adherence to medication. Respiratory disease and cardiovascular and cerebrovasculardisease patients in the fog should insist on to take medicine on time

12、别把窗子关得太严。可以选择中午阳光较充足、污染物较少的时候短时间开窗换气。

12, don't close the window too strict. Can choose to midday when the sunnier, fewer pollutants of shorttime window ventilation.

13、尽量远离马路。上下班高峰期和晚上大型汽车进入市区这些时间段，污染物浓度最高。

13, try to stay away from the road. The rush hour and evening large cars into the city of these time periods, the highest concentration of pollutants.

14、补钙、补维D，多吃豆腐、雪梨等

14, calcium, vitamin D, eat tofu, Sydney

产生雾霾的原因有哪些英语2

我国大气气溶胶浓度高

我国大气气溶胶浓度在世界范围来说处于较高水平，有利于催生雾霾天气的形成。

大气气溶胶是指悬浮在大气中的固态和液态颗粒物的总称,主要包括沙尘、碳(有机碳和黑碳)、硫酸盐、硝酸盐、铵盐和海盐等六大类。

我国各地大气气溶胶有不同的时空分布特点。冬季北方地区燃煤采暖、秋季农村地区秸秆焚烧都会造成碳气溶胶的浓度明显增加;春季，西部地区受沙尘天气影响，以沙尘气溶胶为主。我国华北地区工业相对比较发达，排放的二氧化硫较多，由于气温高可加速二氧化硫转化为硫酸盐，所以夏季华北地区硫酸盐气溶胶浓度较其他季节和地区都高。

气溶胶浓度对能见度的影响非常大，我国气溶胶浓度高是雾霾天气多发的主要原因，而冬季北方地区采暖燃煤释放的大量黑碳则加剧了雾霾的形成。

大气环流异常导致静稳天气多

静稳天气是指当大范围近地面大气层持续或超过24小时出现气压场较均匀、静风或风速较小的天气。在静稳天气条件下，湍流受到抑制，特别是当逆温层出现时，低空中的水汽和颗粒物不易扩散，极易形成雾霾天气。静稳天气在秋冬季更易出现。

近地层大气稳定

大气中污染物和雾霾相互影响和作用，其主要媒介是气溶胶。雾霾中污染物的加入显著改变了气溶胶浓度，可促进水汽凝结，形成更多的云雾滴，水汽凝结时释放的`潜热又有利于雾区的抬升和扩展;另一方面，云雾滴和气溶胶的增加将更多的太阳辐射反射、散射回大气中，使到达地面的辐射减少，地面气温下降，大气层结稳定度增加，造成每日正常排放和转化的气溶胶粒子更易在近地层大气中集聚，能见度进一步降低。

由此可见，气溶胶的增多通过影响近地面层动力和热力场，对雾霾的发展起正反馈作用。

气溶胶二次反应致污染物浓度增高

气溶胶按照形成过程可分为一次气溶胶和二次气溶胶。

人类活动产生的污染源排入大气中，其中二氧化硫、碳氢化合物、氮氧化合物等一次气溶胶通过化学反应和气粒转化过程，形成硫酸盐、硝酸盐和氯化物等新的比较稳定的颗粒，即二次气溶胶。大量观测数据表明，大气中二次气溶胶对PM2.5浓度的贡献很大，大气污染物中有近5成的颗粒物来自于二次反应。二次气溶胶参与形成更多的云(雾)滴，使本已严重的大气污染状况变得更为复杂，雾霾天气更严重。

产生雾霾的原因有哪些英语3

一、对人体产生的危害

1、伤肺。

霾的组成成分非常复杂,包括数百种大气化学颗粒物质。对于支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸系统疾病患者，雾霾天气可使病情急性发作或急性加重。如果长期处于这种环境还会诱发肺癌。

2、伤心脏及血管。

雾霾天对人体心脑血管疾病的影响也很严重，会阻碍正常的血液循环，导致心血管病、高血压、冠心病、脑溢血，可能诱发心绞痛、心肌梗塞、心力衰竭等，使慢性支气管炎出现肺源性心脏病等。

浓雾天气压（气温）比较低，人会产生一种烦躁的感觉，血压自然会有所增高。一些高血压、冠心病患者从温暖的室内突然走到寒冷的室外，血管热胀冷缩，也可使血压升高，导致中风、心肌梗死的发生。

3、雾霾天气还可导致近地层紫外线的减弱，使空气中的传染性病菌的活性增强，传染病增多。

4、不利于儿童成长。由于雾天日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收大大减少，严重的会引起婴儿佝偻病、儿童生长减慢。

5、影响心理健康。

专家指出，持续大雾天对人的心理和身体都有影响，从心理上说，大雾天会给人造成沉闷、压抑的感受，会刺激或者加剧心理抑郁的状态。此外，由于雾天光线较弱及导致的低气压，有些人在雾天会产生精神懒散、情绪低落的现象。

6、影响生殖能力。

有研究表明，长期暴露于高浓度污染的空气中的人群，其精子在体外受精时的成功率可能会降低。研究人员还发现了有毒空气和男性生育能力下降之间的关联 。雾霾天气现象会给气候、环境、健康、经济等方面造成显著的负面影响。

二、对交通和生活环境造成的危害

1、影响交通安全。

雾霾天气时，由于空气质量差，能见度低，容易引起交通阻塞，发生交通事故。在日常行车行走时更应该多观察路况，以免发生危险。

2、影响生活环境。

雾霾天气对公路、铁路、航空、航运、供电系统、农作物生长等均产生重要影响。雾、霾会造成空气质量下降，影响生态环境，给人体健康带来较大危害。
