The harm of haze

Haze weather is very easy to make asthma relapse. It includes bronchial asthma, bronchitis, allergic rhinitis and variant cough, which are mostly related to the recent temperature drop and haze weather. In haze weather, dust, smoke and dust are floating in the air, and dust mites may also be suspended in the fog. When patients with bronchial asthma inhale these allergens, they will stimulate the respiratory tract, cough, suffocation, poor breathing and other asthma symptoms. Every time people breathe, they inhale about 500000 particles deep into their lungs, but in polluted air, they inhale 100 times more particles.

Let the haze go

"Haze" is a well-known word. The fog in Beijing has made us well aware of its harm. However, when we complain, we might as well reflect on our own faults: carbon dioxide everywhere; dust on the ground; floating heavy metals, which are not caused by us. So, from now on, we should protect the environment and give the city a blue sky!

3 haze

A few days ago, we had haze here. All the schools have a day off, just because we are boarding school, so we didn't have a day off. It's really sad!

After class, I look at the distance, looking at the gray day, the mood has become melancholy.

Haze is caused by a large number of automobile exhaust emissions and people's destruction of nature. In order to improve the bad weather, we must protect the environment. This is not only a personal responsibility, but also the responsibility of every citizen of the earth!

Let's take action together to protect the environment and our only place to live - the earth!

4. Nasty haze

In the morning, I looked out of the window. It was gray. The cars and pedestrians on the road are out of sight, only the horn of the car and the voice of people can be heard. Next to the trees, buildings can not be seen, it is really a thick haze!

Do you know how haze is formed? Automobile exhaust, factory smoke, construction site dust, fireworks, firecrackers and so on are the main culprits of haze.

Haze is very harmful to our health. It can cause pneumonia, tracheitis, heart disease and so on.

What a terrible haze! We should not litter and ask Mom and dad to drive less to make the air fresher.

Haze in my eyes

We all know that haze is a harmful substance, but do you know what it contains? It contains a lot of "PM2.5", which can cause great damage to human respiratory tract. In this weather, you'd better not go out. If you have to go out in case of emergency, you should wear "anti haze mask" to go out. How is haze formed? As far as I know, it is the exhaust gas and odor from the chemical plants that form the haze.

Haze has come, our way of playing games has also changed: originally we can play hide and seek, police and thieves, because now with haze, we can't see what ten meters think, so we can't play these two games.

I hope that chemical plants will no longer emit a lot of odor, otherwise, the world will be covered by haze, and then human beings may no longer exist!
