“雾霾”英语怎么说
名词解释：雾霾，是雾和霾的组合词。
雾霾常见于城市。
中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报，统称为“雾霾天气”。
你知道怎么用英语表达吗?
THE Chinese metropolis of Wuhan was yesterday blanketed in a thick haze, with many of the city's people told to stay indoors.
The official Xinhua news agency said straw burning was the cause and denied there had been any industrial accidents in or near Wuhan。
中国大都市武汉昨日被笼罩在雾霾中，而许多市民则被告知待在室内。
官方媒体新华社称，燃烧秸秆是造成雾霾天气的原因，并且否认了武汉及其周边地区发生了任何工业事故。
【讲解】：
雾霾的英语表达就是：haze。
除了有雾霾的意思，haze作名词还有薄雾，迷糊的意思;另外作动词时还有变模糊;戏弄的意思。
不仅是武汉市，包括江苏、安徽在内的中国多个城市都遭到了雾霾的侵袭，而其最主要的原因是因为燃烧秸秆(straw burning)所致。
straw作名词有稻草，麦秆的意思，另外它还有个意思是：吸管。
与straw相关的短语有很多，例如：straw man,是稻草人的意思，其引申义为假象的对手，很容易对付的敌人等。
straw poll：(大选前)意向性投票。
catch at a straw,捞救命稻草。
haze测试标准Haze（雾霾）作为一种空气污染现象，在当今社会已经成为广泛关注的话题。
尤其是在一些发展中国家，由于工业化进程加快及能源消耗巨大，Haze问题日益突出。
因此，为了解决Haze问题，各地区不断进行Haze测试标准的研究，以制定适应当地情况的风险评估及控制措施。
本文将就Haze测试标准的必要性、国内外研究现状及未来发展方向进行简要探讨。
首先，制定Haze测试标准的必要性不言而喻。
Haze作为空气污染的一种，给人们的生活和健康带来了严重的危害。
它不仅直接影响人们的呼吸系统，还会导致眼部不适、皮肤过敏等问题，严重时甚至会引发呼吸道疾病和心血管疾病。
而制定Haze测试标准的目的就在于通过科学客观的手段，对Haze进行准确评估，为相关部门提供依据，制定出相应的控制措施和政策，以保障公众的健康和生活质量。
其次，国内外Haze测试标准的研究现状各异。
在国外，一些发达国家已经建立了比较完善的Haze测试标准体系。
例如美国的“颗粒物污染物标准”将PM2.5（细颗粒物）作为评估Haze的重要指标，限制了PM2.5的浓度。
在欧洲，不同国家和地区也建立了各自的Haze测试标准，如英国的“空气质量规范”等。
这些标准多数以PM2.5、PM10（可吸入颗粒物）等颗粒物为重点，衡量了颗粒物在空气中的浓度和大小，从而判断Haze的严重程度。
国内的Haze测试标准在近年来也有了较大的进展。
尽管相对欠缺系统性，但中国国家环境保护标准委员会已于2013年发布了《环境空气质量指数（AQI）技术规定》等一系列标准，为评估Haze提供了一定依据。
这些标准主要关注颗粒物浓度、臭氧、二氧化硫和二氧化氮等关键污染物，然后通过计算得到“环境空气质量指数”，以提供公众对于空气污染状况的直观认知。
此外，不少城市也根据当地实际情况出台了相应的Haze预警标准，以便更及时有效地进行风险评估和应对措施。
然而，当前Haze测试标准仍然存在一些问题。
英语作文：雾霾来袭 The Haze Has ComeAs we all know, haze has been affecting many cities in China recently. It is a kind of air pollution caused by the emission of air pollutants such as sulfur dioxide and nitrogen oxides.The haze has caused a lot of problems. First of all, it reduces visibility and makes it difficult to drive. Second, it has a great impact on people's respiratory system. People who suffer from asthma, bronchitis and other respiratory diseases may suffer more. Third, it affects the environment. The haze can not only reduce the amount of sunlight and damage crops, but also cause acid rain.In order to solve the haze problem, we need to take some measures. First of all, we should reduce the emission of air pollutants. We should encourage people to use public transportation instead of driving cars. Secondly, we should plant more trees to reduce air pollution. Thirdly, we should strengthen the supervision of industries and punish those who violate the environmental protection laws.Therefore, we should take action to protect the environment. Let us work together to create a better and healthier environment for our future generations.。
英语怎么表达雾霾英语怎么表达雾霾雾霾天气真是讨厌了，既影响视觉又影响健康。
以下店铺整理的英语怎么表达雾霾，希望对大家描述雾霾有所帮助，更多信息请关注应届毕业生网!1. 关于雾霾的表达关于雾霾的表达可是个技术活，英语中关于“雾”“霾”“烟”等的词汇可谓形形色色，一定要闹清楚了，下面举几个比较常见的词汇：fog 雾牛津词典给出的解释是这样的: thick cloud of tiny drops of water close to or just above land or sea;一般指靠近或悬浮于陆地或海洋上空的浓雾，能见度低。
由此可见它的主要成分是水，常常指自然现象中的雾，对人体是无害的。
一般用thick, dense, light等形容词形容。
Dense fog is covering roads in the north and visibility is very poor.浓雾笼罩了北部的公路, 能见度很低。
mist 薄雾牛津词典给出的解释：cloud of minute drops of water vapour hanging just above the ground, less thick than fog but still difficult to see through;一般指薄雾、雾霭、雾气，这里已经很清楚地指出了，mist比fog轻、淡，但能见度仍然不是很高，所以，fog = thick mist。
一般用thick, dense, light等形容词形容。
early morning mists in autumn秋日清晨的薄雾haze 霾The Free Dictionary给出的解释：Atmospheric moisture, dust,smoke, and vapor that diminishes visibility，a partially opaque covering;一般是由大气湿度、尘、烟、水汽等降低能见度的物体或不透明的悬浮颗粒引起的，而霾是指原因不明的大量烟、尘等微粒悬浮而形成的浑浊现象，核心物质是空气中悬浮的灰尘颗粒。
关于雾霾天气资料的收集雾霾天气形成有以下几个方面的原因。
大气空气气压低，空气不流动时主要因素。
由于空气的不流动，使空气中的微小颗粒聚集，漂浮在空气中。
地面灰尘大，空气湿度低，地面的人和车流使灰尘搅动起来。
汽车尾气是主要的污染物排放，近年来城市的汽车越来越多，排放的汽车尾气是雾霾的一个因素。
雾霾天气遇到冬季寒流，导致本市各大医院门急诊患者中，呼吸道感染的患者比例同比明显上升。
据北京市儿童医院统计，1月5日至11日，北京儿童医院日门急诊量最高峰曾达到9000多人次，呼吸道感染占到内科病人的50%左右。
1月中旬，来院就诊的呼吸系统疾患增加了两成，日均接诊100余名患者，已经占到急诊内科总量的一半，其中，既有慢性肺炎者、脑梗塞症状加剧者，也有循环被感染的流感患者。
杨建萍说，天气寒冷，再加上空气污染严重，很容易引起各种呼吸系统疾病，如慢性阻塞性肺病等，“有的流感患者发烧、咳嗽了3个月都没有痊愈，一是因为空气质量太糟糕，二是周边流感患者多导致的交叉感染”。
记者从北京市疾控中心获悉，1月14日至20日，全市二级以上医疗机构累计监测门、急诊就诊人数77万多人，流感样病例占3.3%，但空气不流通导致流感高峰势力得以增强，流感样病例发病水平仍然处于高峰时期。
[11]4.在雾霾天气里我们正确的做法雾霾天气少开窗雾霾天气不主张早晚开窗通风，最好等太阳出来再开窗通风。
外出戴口罩如果外出可以戴上口罩，这样可以有效防止粉尘颗粒进入体内。
口罩以棉质口罩最好，因为一些人对无纺布过敏，而棉质口罩一般人都不过敏，而且易清洗。
外出归来，应立即清洗面部及裸露的肌肤。
雾天的饮食宜选择清淡易消化且富含维生素的食物，多饮水，多吃新鲜蔬菜和水果，这样不仅可补充各种维生素和无机盐，还能起到润肺除燥、祛痰止咳、健脾补肾的作用。
少吃刺激性食物，多吃些梨、枇杷、橙子、橘子等清肺化痰食品。
适量补充维生素D 冬季雾多、日照少，由于紫外线照射不足，人体内维生素D生成不足，有些人还会产生精神懒散、情绪低落等现象，必要时可补充一些维生素D。
科技视界Science&Technology VisionScience&Technology Vision科技视界雾霾(wùmái,英语表达为smog/haze),顾名思义是雾和霾。
但是雾是雾,霾是霾,“雾”和“霾”实际上是有区别的。
国家气候中心气候系统监测室高级工程师孙冷指出,雾是指大气中因悬浮的水汽凝结,能见度低于1公里时的天气现象;而灰霾的形成主要是空气中悬浮的大量微粒和气象条件共同作用的结果。
二氧化硫、氮氧化物以及可吸入颗粒物是雾霾主要组成,前两者为气态污染物,最后一项颗粒物才是加重雾霾天气污染的罪魁祸首。
颗粒物的成分很复杂,主要取决于其来源:自然源和人为源,但危害较大的是后者。
它们与雾气结合在一起,让天空瞬间变得灰蒙蒙的。
其中,自然源包括土壤扬尘(含有氧化物矿物和其他成分)、海盐(颗粒物的第二大来源,其组成与海水的成分类似)、植物花粉、孢子、细菌等,自然界中的灾害事件,如火山爆发向大气中排放了大量的火山灰,森林大火或裸露的煤原大火及尘暴事件都会将大量细颗粒物输送到大气层中;人为源包括固定源和流动源。
固定源包括各种燃料燃烧源,如发电、冶金、石油、化学、纺织印染等各种工业过程、供热、烹调过程中燃煤与燃气或燃油排放的烟尘。
流动源主要是各类交通工具在运行过程中使用燃料时向大气中排放的尾气。
随着空气质量的恶化,阴霾天气现象出现增多,危害加重。
中国不少地区把阴霾天气现象并入雾一起作为灾害性天气预警预报。
统称为“雾霾天气”。
其实雾与霾从某种角度来说是有很大差别的。
雾霾天气是一种大气污染状态,雾霾是对大气中各种悬浮颗粒物含量超标的笼统表述,尤其是PM2.5(粒径小于2.5微米的颗粒物)被认为是造成雾霾天气的“元凶”。
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。
雾霾现象常见于城市,但各地区的雾霾天气中,不同污染源的作用程度各有差异。
什么是雾霾?雾霾天气形成的原因?雾霾天气的危害?什么是雾霾?雾霾天气形成的原因?雾霾天气的危害?雾霾（wùmái,英语表达为smog/haze），顾名思义是雾和霾的组合词。
雾——雾是由大量悬浮在近地面空气中的微小水滴或冰晶组成的气溶胶系统。
霾——霾（mái），也称灰霾（烟霞），是空气中的灰尘、硫酸、硝酸等颗粒物组成的气溶胶系统造成的视觉障碍。
霾与雾的区别在于发生霾时相对湿度不大，而雾中的相对湿度是饱和的。
当水汽凝结加剧、空气湿度增大时，霾就会转化为雾。
雾霾常见于城市。
中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报，统称为“雾霾天气”。

它们与雾气结合在一起，让天空瞬间变得灰蒙蒙的。
颗粒物的英文缩写为PM，北京监测的是PM10，也就是空气动力学当量直径小于等于10微米的污染物颗粒。
除了气象条件，工业生产、机动车尾气排放、冬季取暖烧煤等导致的大气中颗粒物（包括粗颗粒物PM10和细颗粒物PM2.5）浓度增加，是雾霾产生的重要因素。
雾霾的危害：雾霾天气易诱发心血管疾病，雾霾天气时气压低，湿度大，人体无法排汗，诱发心脏病的几率会越来越高。
诱发呼吸道疾病，雾霾中含有大量的颗粒物，这些包括重金属等有害物质的颗粒物一旦进入呼吸道病粘着在肺泡上，轻则会造成鼻炎等鼻腔疾病外，重则会造成肺部硬化，甚至还有可能造成肺癌。
雾霾天气时光照严重不足，接近底层的紫外线明显减弱，使得空气中细菌很难被杀死，从而传染病的概率大大增加。
雾霾天气时，由于空气质量差，能见度低，容易出现车量追尾相撞，影响正常交通秩序，对大家出行造成不变，在日常行车行走时更应该多观察路况，以免发生危险。
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。

雾霾会造成哪些危害和应对措施英语作文Hazards and Countermeasures of HazeHaze, a pervasive environmental issue, has become a significant threat to human health and the ecological system. It is essential to understand the various hazards of haze and implement effective measures to mitigate its impact.One of the most significant hazards of haze is its adverse effect on respiratory health. The fine particles present in haze can penetrate deep into the lungs, causing irritation and inflammation. Long-term exposure to haze can lead to chronic respiratory diseases such as asthma, bronchitis, and even lung cancer. Children, elderly individuals, and those with pre-existing respiratory conditions are particularly vulnerable.Furthermore, haze can also impact the cardiovascular system. The pollutants in haze can trigger cardiovascular events such as heart attacks and strokes. This is becausethe fine particles can enter the bloodstream and affect the functioning of the heart and blood vessels.In addition to health hazards, haze also poses a threatto the ecological system. It can reduce the amount of sunlight reaching the earth's surface, affecting photosynthesis and the growth of plants. This, in turn, can disrupt the food chain and the balance of the ecosystem.To mitigate the hazards of haze, several measures can be implemented. Firstly, reducing emissions from industrialand vehicular sources is crucial. This can be achieved by adopting cleaner technologies, enforcing emission standards, and promoting the use of renewable energy.Secondly, promoting green urban planning andconstruction can help reduce the concentration ofpollutants in urban areas. This includes increasing green spaces, planting more trees, and using environmentally-friendly building materials.Moreover, raising public awareness about the hazards of haze and encouraging individuals to adopt sustainable lifestyle choices is also essential. Simple habits like using public transport, cycling, or walking instead ofprivate vehicles, reducing energy consumption, andrecycling can contribute to reducing emissions andimproving air quality.Lastly, governments need to take a proactive role in implementing policies and regulations to address the issueof haze. This includes enforcing stricter emission standards, providing incentives for clean energy adoption, and investing in research and development of technologiesto reduce emissions.In conclusion, haze poses significant hazards to human health and the ecological system. To mitigate its impact,we need to adopt a comprehensive approach that includes reducing emissions, promoting green urban planning, raising public awareness, and implementing policies and regulations. Only by working together can we address this pressing environmental issue.雾霾的危害及应对措施雾霾作为一种普遍存在的环境问题，已对人类健康和生态系统构成严重威胁。
雾霾时代何处安身英语作文1英文作文：These days, smog has become an unwelcome guest that lingers around us. On a particularly hazy day, I woke up to find the world outside my window engulfed in a thick, greyish fog. It was as if a mysterious veil had descended, obscuring everything in its path.I had been looking forward to going for a run in the park, but the heavy smog made it impossible. Disappointed, I stood by the window, gazing out at the gloomy scene. The trees that usually stood tall and proud were now mere shadows, barely visible through the haze. The park, which was usually filled with people enjoying the outdoors, was deserted.As I watched, people hurried by on the street below, their faces hidden behind masks. They walked quickly, as if trying to escape the smog as soon as possible. It was a strange sight, and it filled me with a sense of unease.I couldn't help but wonder how we had let things come to this. How had we allowed our environment to deteriorate to such an extent? The smog not only affected our daily lives, making it difficult to breathe and enjoy outdoor activities, but it also served as a stark reminder of our responsibility to protect the environment.We need to take action now. We can start by reducing our carbon footprint, using public transportation more often, and conserving energy. Only by working together can we hope to rid our world of smog and create a cleaner, healthier future for ourselves and generations to come.中文翻译：这些日子以来，雾霾已经变成了一个不受欢迎的客人，在我们周围徘徊不去。
雾霾时代何处安身英语作文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 people's 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 changesduring 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.。
[雾霾天气形成的原因]雾霾形成的主要原因雾霾形成的主要原因篇一:雾霾产生的原因英语作文Recently, the fog haze weather occurred frequently, more and more serious, and also attracted the attention of the national people"s attention. Many parts of China the haze as a severe weather forecast.How is the haze formation? Please listen to me to slowly. It is made of pm2.5 grain of dust, smoke, such as sand float evenly to form a haze in the air. However, fog and haze and difference in nature. When the air is humid, appear when fog haze air drying, and harmful to human body, long-term inhalation can lead to death.Haze is how to produce? Automobile exhaust emissions from industrial production, and firecrackers and so on all is the main cause of haze. Drive a little, little let off firecrackers at a time. Let we Chinese don"t neglect environmental protection.However, relative to protect themselves is to some. In order to avoid inhaling fog, fog weather don"t open the window. Goout to travel, or play, please wear the masks. Tung orange stem tea, and a moderate amount of vitamin d supplements.

Haze TimeAbstract:This passage is mainly about haze, including the definition of haze, the causes of haze, hazards of haze and ways to control haze. And it introduced the details of haze from four parts above. Briefly, Haze, as the name suggests that, it is fog and haze.And two main points composed the causes of haze, which are human activities and climatic factors. Meanwhile, there are also two main respects of the hazards of haze, that is，the harm to the human body and the hazards on the environment and traffic. Therefore,governing haze cannot alone be the task of environmental protection departments but the responsibilities of all people. All of us are supposed to take actions to control haze and protect our family.As we all know, last year, many cities in our country especially some big cities, such as our nation’s capital Beijing, industrial city Tianjingand so on, were covered by haze, so we went into a Haze Time in 2014. Unfortunately, haze was not eliminated thoroughly, and this year 2015 we are still puzzled by haze and something that it brings to us. Therefore, it is necessary for all of us to know about haze, to be familiar with it and to do something to control it.I will introduce it from four parts: what is haze,the causes of haze, hazards of haze and ways to control haze.1.What is haze?Haze, as the name suggests that it is fog and haze. But there is a big difference between the fog and haze. Visual impairment caused by the composition of aerosolparticles of dust in the air system, sulfuric acid, nitric acid called haze.Fog is an aerosol system which is composed of a large number of tiny water droplets or ice crystals in the air suspended near the surface.Fog and haze is a state air pollution, haze is excessive levels of suspended particulate matter in the atmosphere of a variety of general statements, especially PM2.5 (aerodynamic equivalent diameter less than or equal to 2.5 micron particles) is considered to be caused by haze weather "culprit." With the deterioration of air quality, haze weather phenomenon increases, harm increase. China in many areas of the haze foggy weather phenomena are incorporated together as severe weather warning and forecast. Collectively, the "fog and haze"2.Causes of hazeThere are two main aspects that caused haze. One is humans’ activities, the other is climatic factors.(1)Humans’ activitiesIt is safe to say that there are too many aspects of humans’activities which produced too much polluted air.For example, the first and foremost is automobile exhaust. Large diesel vehicles are the "felon" of emissions of PM10, including large buses, each unit of the bus, as well as large transport trucks. Of course, Exhaust gas emissions in industrial production are another aspect. Such as metallurgy, furnaces and boilers, electrical and mechanical manufacturing, as well as a large number of automotive paint, building materials production and combustion exhaust gas from the furnace.The last but not the least is the exhaust gas generated by heating coal in winter in the north of our country.(2)Climatic factorsActually there is a difference between fog and haze. Fog refers to the atmosphereweather phenomenon due to the suspension of condensation, when visibility is less than 1 km. However, the formation of haze is primarily a large number of particles suspended in the air and weather con dition’s joint action, causes are three:Firstly, it is the increase in the lateral static wind phenomenon.The buildings of the city are building higher and higher, which results in the phenomenon that blocking and friction make wind reducesignificantly over time. Static wind phenomenon increased, the atmosphere is not conducive to the spread dilute aerosols, tend to accumulate in the city and surrounding suburban areas.Secondly, the inversion occurs in the vertical direction.Inversion like a lid covering over the city, thisinversion phenomenon of high-altitude temperatures higher than the temperature at low altitude, makes some constraints of the vertical motion of the atmosphere at lowaltitude,therefore it is not easy to diffuse to the high altitude but limited at low altitude and near the ground.Thirdly, the increasing organic pollutants in the air suspended particles. With population growth and industrial development of cities, motor vehicles soared,leading to a significant increase in pollutant emissions and suspended solids.3.Hazards of haze3.1Harm to the human body(1) The impact on the respiratory systemThe compositionof haze is very complex, involving hundreds of atmospheric chemistry particulate matters, among which the harmful to our health is mainly less than 10 microns in diameter aerosol particles such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, gas and other fuel and cars that can go directly to and adhered to the human respiratory tract and alveoli. Especially sub-micron particles will be deposited separately in the upper and lower respiratory tract and alveoli, causing acute rhinitis and acute bronchitis and other diseases. For the patients of bronchial asthma, chronic bronchitis, emphysema and chronic obstructive pulmonary disease and other chronic respiratory diseases, fog and haze can make the disease more seriously or acute exacerbation. In the long run, people who always livesuchkind of environment will induce lung cancer.(2)The impact on the cardiovascular systemHaze days can affect human cardiovascular and cerebrovascular diseases very serious and will hinder normal blood circulation, leading to cardiovascular disease, hypertension, coronary heart disease, stroke, which may induce angina, myocardial infarction, heart failure, so that chronic bronchitis appears pulmonary heart disease.In addition, fog weather has relatively low pressure, which makes people produce a feeling of irritability, and blood pressure will naturally be higher. A further aspect isthat temperature ofthe fog often low, somepatientsof hypertension, coronary heart disease in a warm room suddenly went cold outdoors with vascular expansion and contraction, and the blood pressure also increase and lead to stroke, myocardial infarction. Therefore, patients with heart cerebral blood must take medication carefully.(3) The fog and haze formation can alsoweaken near ultraviolet, so that the air active infectious germs enhanced, and increased infectious disease.(4) It is not conducive to children's growth. Because of reducing of sunlight, child is lack of ultraviolet radiation, vitamin D deficiency is generated, greatlyreducing the absorption of calcium, which can cause severe rickets to infants, and childrenwill grow slowly.(5) The affect to mental healthExperts point out that continued foggy day are affectedon the person's mental and physical, psychologically, foggy day give people dull, repressed feelings, which will stimulate or exacerbate mental state of depression. In addition, because fog and low pressure leads to low light, some people will have the spirit of idleness and depression phenomenon in the foggy day.(6) The impact on reproductive capacityStudies have shown that long-term exposure to high concentrations of air pollution in the crowd, the sperm during IVF success rate may be lowered. The researchers also found an association of toxic air and the reducing ofreproductive capacity among men.3.2The hazards on environment and traffic(1) The impact on traffic safetyWhen in the fog and haze day, the air quality is poorer, and the visibility islower, which is easy to cause traffic congestion and traffic accidents. In everyday driving and walking people should observe the road, to avoid danger.(2) Cloudy weather yields morecancer.When a serious shortage of light in fog and haze day, the ultraviolet close to the bottom of the horizon significantly reduced, making it difficult to kill bacteria in the air, thereby greatly increasing the probability of infectious diseases. The academician of Chinese Academy of Engineering, ZhongNanshan, director of the Guangzhou Institute of Respiratory Diseases has pointed outin a forum that, the past 30 years, our public smoking rates continue to decline, but the rate of lung cancer increased by 4 times. This may have a certain relationship with the increase of the haze days. Not only wrapped fog, very low visibility will affect human health, sometimes cloudy and foggy weather will have the same problem.(3) The affection on the ecological environment.Fog and haze have a major impact on road, rail, aviation, shipping, power supply system, the growth of crops etc. Fog, haze will result in decreased air quality,ecological impacts, and do greater harm to human health.4.Ways to control hazeGoverning haze is not an easy thing, but it is not no way, we pay for whatever we did, the best way is to reduce the amountof fuel use of motor vehicles.Beijing Municipal Environmental Protection Bureau Director at the vehicle emission management even clerk accepted the First Financial Daily correspondent telephone interview, also said that a quarter of PM2.5 in Beijing is imported, and three-quarters is produced in the Beijing region. Among them, thecontribution rateof automobile exhaust is more than 22%. Therefore, vehicle exhaust is the focus of Beijing PM2.5 Prevention attack objective."Reducing pollution sources, reduce air pollution is to solve the root of the haze." Institute of Atmospheric Physics, Chinese Academy of Sciences researcher Wang Dragon said. Beijing Economic and Information Technology Committee, deputy director Li said, according toEmergency Plan about Beijing's Heavy Air Pollution Day emission reduction in key enterprises in Beijing a total of 58 enterprises stop producing, completely cut off the sources of pollution; 41 enterprises reduced production load, reduced pollution of supply and demand, achieved more than 30% of pollution reduction; strong United Cement, Pinggucement Plant etc. achieved full shutdown, the cement industry has achieved more than 30% of the emission reduction task.To minimize dust contact betweendowntown car wheels and the road surface frequency and area, flowerbeds and curbs should be made lower than automobile traffic road, so rain whey and pollution watering will flow flower garden soil under the middle of the road. Unfortunately, we rarely observe this dust pollution prevention granule design in 350 cities in our country.Similarly, in order to maximize the isolation of dust brought by the outside vehicles and construction vehicles, we can set up water cleaning the tires of the vehicle outside the city with dust (coal cars and other long-distance trucks, etc.) in the city pass toll stations side, chassis links clean up prevention mechanism established to cover the city at the time of construction vehicles entering the street and cleaning tires, chassis part, but many cities are often only a fine mechanism terminal into the cityand not into the city after the time. Visibly, the lack of urban infrastructure construction dust governance requirements, lack of preventive mechanisms act constitutes is the first source of haze, the number of construction sites and economic development and the scale is only second-order pollution.The goal ofa lot of urban environmental pollutiongovernancestill deviated particulate haze. Meanwhile, the emergence of haze is the lack of institutionin depth system. Governance haze cannot alone be the task of environmental protection departments, local governments and the central government should establishparticle pollution prevention general and implement rules in line with the reality of Chinese geographyas soon as possible, urging the city administration and the construction sector toimplement in accordance with the standard, and implementthe details above in urban construction, landscaping bidding processas soon as possible, open the relevant connecting factor market, and promote the construction unit, construction of the building sectorto construct in accordance with environmental philosophy. Finally, proposalsfor the ordinary people it repaired should appear in the NPC andinthe visionofmembers, to lead the community to proceed from the subtletogovern haze.。
