\u96fe\u973e\u539f\u56e0This 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.

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.

his winter fog and haze much of our attention, haze harmful, several cities have in its move, so we should strengthen environmental management efforts, not let the fog and haze rampant.
Causes haze presumably a lot of people know, haze you, of course, by the fog and haze is composed of a large number of the main causes of fog suspended in the air, ground water droplets or ice crystals composed of tiny aerosol system, is near the ground floor air, water condensation product. The main causes fog reduced visibility, it will cause traffic problems, but there is little risk to people.
Haze is dust in the air, sulfuric acid, nitric acid and other harmful material composition, it will make the atmosphere muddy, blurred vision and lead to reduced visibility, and the body will cause greater damage. As a result two of the incoherent fog and haze The brothers came together, causing unprecedented damage to the atmosphere, the air quality in some cities has reached a point where moderately polluted, but some cities have reached the severe pollution, very terrible.
Haze considerable harm, it would be road, rail, aviation, power supply systems, crop growth impact is also easily lead to the spread of infectious diseases and a variety of diseases. Endanger human health. And will lead to air pollutants easy to spread enhance the toxicity of harmful substances, severe, may also lead to smog occur. and would have caused great harm, especially a great impact on the respiratory system. It is reported that the incidence of human respiratory system in winter than last winter an increase of 30% --- 40%. This is an astonishing figure, worthy of our consideration. Therefore, prevention of fog and haze delay.
Our preventive measures should be in place, in the fog and haze, we should stop doing morning exercises and outdoor sports. But this is not enough, I think the main reason for this bad weather is vehicle exhaust emissions and industrial waste gas emissions, so the state should be issued as soon as possible policies to manage and control the emission of harmful gases, more trees and grass, clean up our environment. I think that if we are mobilized, fog and haze should be crestfallen to escape it.
In conclusion, I hope that we can take action, many grass flowers, more to protect the environment, create a green for our future generations, the natural environment.
On January 28, China's central and eastern regions in a broad range of haze weather, the ash haze area exceeds 100 square kilometers. The national meteorological center outside the fog warning, also issued a haze of blue warning signal
Is that when the haze of relative humidity is not big, and the relative humidity in the fog is saturated (such as the presence of a large number of condensation nuclei, relative humidity 100% saturated) may appear not necessarily.
Haze weather graphic symbol average relative humidity is less than 80% when the atmospheric turbidity of blurry vision led to the deterioration of visibility is caused by haze, when relative humidity is more than 90% of atmospheric turbidity blurry vision led to the deterioration of visibility is caused by fog, when relative humidity between 80-90% of atmospheric turbidity blurry vision led to the deterioration of visibility is caused by a mixture of haze and fog together, but its main component is haze. The thickness of the haze is thick, up to 1-3 km. Haze and fog, cloud, with no obvious boundary between sky area, haze particles distribution is more even, and the scale of the ash haze particles is small, from 0.001 micron to 10 microns, the average diameter of about 1 to 2 micron, invisible to the naked eye of air floating particles. Because the particles such as dust, sulfuric acid, nitric acid haze, the longer light scattering wavelength is more, so look yellow or orange gray haze.
Haze formation has three elements: one is the physical base of granularity dust generated source. Our country has the world's largest in loess plateau area, the soil texture are the most easy to granularity dust particles. The second is movement caused by dust. The middle of the road, for example, flower beds and street after rain or water in the soil of the road opposite sides-to hold if any mud flow to the road, an hour after drying, was the wheel a spin can cause a lot of dust, even if the particulate material falls back to earth, also can by car drove by, was once again to the city. Three is the difference in dust source and movement process of concentration within a certain space, TB gathered into a haze particles with water molecules. Now, more than 350 cities in flat loess plateau region in our country, the fog haze of the three elements of structure quite abundant stocks.
My friends, the earth would damage like this? What's the reason to continue to be broken? Let's take action together to protect our earth.
我们身边的环境已经受到了严重的破坏，就拿最近各地的雾霾天气来说。
1月28日起,中国中东部地区出现了大范围的雾霾天气,全国灰霾面积超100万平方公里。中央气象台在大雾预警之外,也同时发布了霾蓝色预警信号
在于发生霾时相对湿度不大，而雾中的相对湿度是饱和的(如有大量凝结核存在时，相对湿度不一定达到100%就可能出现饱和)。
雾霾天气图形符号一般相对湿度小于80%时的大气混浊视野模糊导致的能见度恶化是霾造成的，相对湿度大于90%时的大气混浊视野模糊导致的能见度恶化是雾造成的，相对湿度介于80-90%之间时的大气混浊视野模糊导致的能见度恶化是霾和雾的混合物共同造成的，但其主要成分是霾。霾的厚度比较厚，可达1-3公里左右。霾与雾、云不一样，与晴空区之间没有明显的边界，霾粒子的分布比较均匀，而且灰霾粒子的尺度比较小，从0.001微米到10微米，平均直径大约在1-2微米左右，肉眼看不到空中飘浮的颗粒物。由于灰尘、硫酸、硝酸等粒子组成的霾，其散射波长较长的光比较多，因而霾看起来呈黄色或橙灰色。
雾霾形成有三个要素：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平高原地区，其土壤质地最易生成颗粒性扬尘微粒。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。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。
朋友们，地球都破坏成这样了?我们还有什么理由继续破环下去呢?让我们行动起来一起保护我们的地球吧。
