The last item for the particulate matter is the home haze weather pollution is the culprit, they combine with the fog, is the weather becomes dim to see the sun, this particulate matter itself is a pollutant and a heavy metal, these diameters less than or equal to 2. 5 micrometers Uranium, is a heavy metal, the source of toxic particles in the city, first of all, the exhaust of automobiles, use of diesel cars is a cardboard house, the recidivism of fine particles. The use of gasoline small cars, although the emission of nitrogen oxides, but happen to be foggy days, it is easy to convert into secondary particles of pollutants, aggravate the haze.

The reason for the formation of haze is very complex but also very simple, are human greed to lead to such a scourge, desire is the source of all evil, we should restrain their own desires, for example, less cutting trees, do not set off fireworks, entrepreneurs should grasp their own conscience, to reduce the pollution of the air by chemical products, or to drive a small emission of cars, live a low-carbon life, as the country can not only a As a country, we should not only aim at GDP, but also combine spiritual civilization and material civilization, and purify the social atmosphere, so that we can defeat the enemy of haze.

The first time I realized that there was a haze was one day in the winter of 20xx, a morning of school, I walked along the north road of Gongtibei Road to the subway station. Suddenly I remembered a saying, "You can't see low clouds on a cloudy day in Beijing, but rather it looks like it's polluted." The air was choking that day, I remember. I just didn't know at the time that it was hazy.

I found it foggy outside, even the mountains could not be seen clearly, and the sun was lazily hiding under the covers and refusing to get up, visibility was very low.

I'm very strange, I ran to ask my mom, my mom told me: "usually people say that the haze is actually made up of fog and haze of the two kinds of weather, haze weather looks like a fog, but in fact there is a big difference. Fog is formed by the condensation of water vapor in the ground air, while the haze is due to the very fine dust particles in the air, fine sand particles, virus particles, etc. evenly suspended in the air, they are intertwined is hazy weather. This kind of weather is very harmful to the human body, if we inhale these bacteria, viruses, it is easy to get sick, and in serious cases, it will kill."

As far as I know, hazy weather is caused by secondary pollution such as car exhaust, factory emissions, etc. So now we should protect the environment and take care of our home to keep hazy weather away from us, in addition to reducing outdoor activities and drinking more boiled water.

Essay about the haze 3

Hello, everyone! I am the famous haze.

Recently I am visiting Nanjing. Seeing Nanjing has so much car exhaust, so much dust from construction sites, so much exhaust from chemical plants ......... haha! Isn't this welcoming me? In people's sight, far away from the only gray this color. They can't see the green of the trees, can't see the colorful flowers, can't see the white walls and black tiles of the buildings, and can't even see the people walking across the street....... All the scenery is shrouded in my control.

If people don't wear masks, I will get into people's lungs, one by one, blocking their alveoli, then they will cough, pneumonia, and serious lung cancer. I would ground airplanes, and pilots would be disoriented in the sky and unable to land. I will also make the car on the ground can not move, the driver looks around, except can see my huge body, can not see anything.

Quietly, I have many natural enemies! Heavy rain, snow, wind, weather cooling, flowers, trees, masks and purifiers are my natural enemies. In the midst of heavy rain and snow landing, I follow the rain and snow slowly down to the soil. High winds whistling and weather cooling break me into pieces. Flowers and trees and air purifiers can suck me out. Masks, mamma mia, with them I can't get into people's bodies.

Ha ha! This is me, are you afraid!

Open the window, the world in front of you today is not as clear as in the past, so real, but gray, some "dark" feeling. Outside of all the scenery is like a layer of light veil, vague, if any, can not see their real face. "I think this foggy weather is caused by the haze!" I said to myself.

In the computer, type in the word "haze", click on the answer, the introduction of the eyes 'is such a paragraph: "Haze, as the name suggests is fog and haze. Sulfur dioxide, nitrogen oxides and respirable particulates are the three main components of the haze, the first two are gaseous pollutants, the last particulate matter is to aggravate the haze weather pollution is the main culprit. They combine with the fog to make the sky instantly gray." Oh, the original cause of "dark sun" is the culprit particulate matter pm10 ah! I nodded thoughtfully and continued to look down.

But in normal times? This haze seems to be rarely mentioned, as if it is very, very far away from us.

We should be prepared before the harm comes, improve our living environment, drive less, reduce emissions from industrial production and so on, these are the ways. We should save for a rainy day in order to keep ourselves away from the harm.

Out can wear a mask, which can effectively prevent dust particles into the body. Mask to cotton mask is the best, because some people are allergic to non-woven fabrics, and cotton masks are generally not allergic to people, and easy to clean.

Today's weather is really strange, the morning is still a cloudy day. At about 6 o'clock in the afternoon, the sky gradually flooded with a thin layer of fog, shrouding the distant hills.

I thought it was just the night hazing the sky. After five minutes, when I again crouched in the window to look into the distance, accidentally found the window glass more than some particles of small water droplets, carefully examined, each small water droplets contain a small black dust particles, I was very strange. And then look into the distance, tall buildings as if tied on a soft white veil, neon lights embellished with ribbons are more and more misty; parking lot on the passing car also opened the fog lamps, shooting lights as a pillar of light, it is very enduring.

The foggy amiability that had just been there was also blown out of existence.

Gee, isn't this the haze phenomenon described in the nature books?

I turned out a thick copy of "100,000 Reasons" at home, ha, finally found it - yes, this is haze! It is because the air suspended in a large number of smoke, dust and other particles encountered moisture and the formation of turbidity phenomenon, so that blurred vision and lead to reduced visibility.

Hearing this, you must want to ask where that pesky haze comes from, first of all, is man-made reasons: cold winter will be seventy percent of the people with coal-fired heating, which is not environmentally friendly, but will make the air emission of soot, and then dry winter, the ground of the people and traffic to make the dust churning up, and secondly, is the natural causes.

Although the beautiful world produces haze, but people have countermeasures to deal with it: less go out, less open windows, away from home to go out with a mask, pay attention to personal hygiene ......

These days, the fog filled the entire campus, the humid air as if you can smell the smell of rain.

The haze is made by humans, it can be said that he is innocent. Because he would have stayed in the atmosphere well, at most into water droplets to the ground, so you can also moisturize the earth. Do not want a lot of exhaust gases gushing up to the clouds, so that he produced mutations, only later said the haze. Being known as the air invisible killer haze heart aggrieved, obviously the mistakes made by mankind, why let him to bear it. Now human beings are aware of the protection of the environment, but also alert to now to protect the home, but the increasing number of buildings and gradually reduce the planting area and greening and how to explain it?

Early this morning, I woke up with a good mood, but look out the window, my warm heart all of a sudden cooled half, due to the fact that, today, I ran into the weather I hate the most - haze.

In many articles, the fog is depicted very soft, but why the haze is not as soft as the fog in the text? In fact, this is a very good solution to the problem, the answer is related to the usual organs of everyone's life: automobile exhaust, chemical plants discharged toxic gases and dust can cause haze. Seeing the day afternoon was the same as usual, but, this morning almost scared me to death. Here's the thing."

Early this morning, I woke up in a good mood and looked out the window to see what I hoped would be buildings and early risers across the street. But what I saw and what I hoped for was not the same at all, what I actually saw was a white scene, our family lives on the sixth floor, not very high, but from the balcony to look down, even the tall trees can not be seen. My dad told me that today's weather was very polluted and that I needed to wear a mask or else I would get bronchitis and other diseases. So I put on the mask. Since I had to go to the Children's Palace to learn dance, my dad had to drive, which brought me to the place I was most afraid of: as soon as I got into the car, I looked out the front windshield, and the visibility was less than 20 ten meters, which was too scary! Dad truck time, I believe that dad must be very nervous, in fact, I am also very nervous, because I grew up, never seen such weather is too scary. The mode of going to school on the way to be cautious and fearful, all the way to the atmosphere do not dare to breathe a bit. I never want to see this kind of weather again, then I have to start from myself, start from the side.

A terrible fog creeps in unknowingly. Looking out, you can only observe the white blanket, the streets are filled with fog, the school should also be closed. A beautiful day had become monotonous because of this ghostly weather. Surrounded by only a white gray, when driving, people have been unable to see the road ahead, as if into a blinding hole. Most car owners turned on their two-way lights and drove by feel, but many cars were involved in accidents. People stopped going out, and those who went out put on masks. Because this ghost weather not only affects the line of sight, the human body is also harmful, it is said that the human respiratory system will reduce the defense function and breathing is not smooth, chest tightness, dry cough and throat dry itch, etc., it is more harmful than the "second-hand smoke" has been no better, and the seriousness of the death of a person may be.

However, we may want to think about what makes us originally healthy become so dangerous? It is that the factory emissions of black smoke, is that the road more than one day more than the car emissions out of the tailpipe, is that the fireworks produced by the smoke, or that after the straw combustion of smoke in the sky ...... environment will become so, are because people themselves produce the bitter fruit. If people can no longer pollute the environment, our homes will not suffer, our personal safety will not be threatened.

At this moment, I sincerely hope: people can wake up from this matter, no longer do harm to their own things. Let us contribute to a clean home
