The air in China is bad!

This news soon appeared in the international media. As for Lin Feng's three glasses of wine, Donald told the American escorts not to tell, and no one in China dared to say so, so the outside world didn't know. The focus of the outside world is on China's poor air quality.

The first country that the president of the United States chose to visit was China. Well, as a result, he came directly to China for seven days. This is wonderful! In the United States, shoes can't be polished for a month, but they are still shiny. As a result, when I arrived in China, I just polished my shoes, and when I went out, it was dirty.

Just washed clothes, out, dirty. Just blow the hair, go out, chaos! What goes out is a layer of ash. It's hard to stand outside for a while, go in and not take a bath.

This kind of weather, also hold the Olympic Games? How can athletes compete in such bad weather? This competition, that is suicide! This is totally killing the lives of athletes! This kind of weather holds the Olympic Games, that is completely takes the life in the movement!

All kinds of comments are overwhelming at this time. And this, let China up and down is a piece of embarrassment, a piece of shame. Take a look at the blue sky and white clouds in foreign countries, and then take a look at the yellow sand in China. This is a life in heaven and a life in hell.

And just then, something more desperate came out. That's the PM2.5 index that has changed Chinese people's perception.

The US embassy announced that the PM2.5 index of Beijing is as high as 380!

What is PM2.5? All of them were puzzled, and what was it!

Then, some netizens found the explanation of PM2.5 index on Baidu Yahoo.

PM2.5 refers to the particles with aerodynamic equivalent diameter less than or equal to 2.5 microns in the ambient air. It can be suspended in the air for a long time. The higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component in the earth's atmosphere, it has an important impact on air quality and visibility. Compared with the coarser atmospheric particles, PM2.5 has smaller particle size, larger area, stronger activity, easy to carry toxic and harmful substances (such as heavy metals, microorganisms, etc.), longer residence time in the atmosphere and long transportation distance, so it has greater impact on human health and atmospheric environment quality. The chemical composition of fine particles mainly includes organic carbon (OC), elemental carbon (EC), nitrate, sulfate, ammonium salt, sodium salt (Na +) and so on.

Generally speaking, this kind of fine particles is produced naturally mainly by volcanic eruption, which releases a large amount of volcanic ash into the atmosphere, forest fires or naked coal fires and dust storms, which will produce a large number of fine particles. People will feel uncomfortable if they are near and absorb into the body. But it's just natural. It's a little better.

The real trouble is the fine particles of human activity. Such as power generation, metallurgy, petroleum, chemistry, textile printing and dyeing and other industrial processes, heating, cooking process of coal and gas or fuel emissions. The flow source is mainly the exhaust gas emitted to the atmosphere by all kinds of vehicles when using fuel in the process of operation. These fine particles are generated from the chemical industry, so the fine particles produced by them do great harm to human body.

It's not as simple as choking. After the fine particles are absorbed into your body, you can't get rid of them when you eat cow's blood. No matter how much you eat, it's useless. It will always be absorbed in your body, in your lungs, and then slowly absorbed and digested by your body, and finally become cancer. At that time, you'll be in big trouble. And this kind of cancer, it can be said, you do not know the cause of the disease, there is no way to treat.

And chemotherapy didn't work. Because it's rooted in your body, it can't be solved by chemotherapy. The end result is a slow death.

Seeing these explanations, everyone was shocked to death. So, how high is the 380 index?

Of course, Baidu Encyclopedia has an explanation.

Tokyo, a prosperous metropolis, has an average PM2.5 index of around 30. This is Tokyo! Even in the rush hour, its PM2.5 index is capped at 50. On this side, 380 is nearly ten times that.

If you look at London, pm2.5,40 is a little higher than Tokyo, but also far lower than China. In New York, the PM2.5 index is higher, about 70, but even 70 is far from being comparable to China.

As for Germany, France and other countries, let alone Japan and Tokyo. If it's not a prosperous metropolis, don't mention the index. Basically, it's about 10. This index is a hopeless figure for Chinese people.

10, that's 38 times the gap. That's a big gap, isn't it!

Is the data accurate? Obviously, the vast majority of Internet users believe that their data is accurate. Because it was announced by the US embassy. In this case, the U.S. Embassy will never maliciously slander China. People believe that the U.S. Embassy can't do this. After all, in the hearts of the people, the United States still has this integrity.

But if so, don't we live in a big pollution source? If we go on like this, won't we all get cancer? Will die in pain! All the people panicked. Almost, for the first time, the streets were covered with masks. All people travel, the essential thing is the mask. I can't help it. It's so powerful. Can they not wear masks.

Of course, it's a little comforting that there are no people living in the imperial capital. The pollution index of this city is high. Other areas should be OK. They should not have to worry. But then, "Baidu Yahoo" announced the PM2.5 index of all parts of the country, and once this index was published, it shocked the whole country.

All regions of the country, the north, are basically 200 +, while the south is slightly better, but there are also more than 100. Compared with foreign countries, this figure is obviously not up to standard. The only places with better air quality in China are Hainan Island and some mountainous areas in Yunnan. The air index of these places is similar to that of foreign countries. Of course, it's about the same, mainly compared with New York. Compared with Japan, it still can't be compared.

In China, no matter how low the air index is, it is above 50. If you want to reach 10, it's impossible to go to other places except the virgin forest, such as Shennongjia.

Shocked! Except for shock! Or shock! No one thought that we were living in poisonous gas. In addition to people's doubts about the data released by Baidu Yahoo, everyone is looking at the country and wants to see how it can solve the problem.

But in fact, the state can't solve it. If society wants to develop, pollution is inevitable. For example, in developed countries, pollution is first treated and then treated. For example, the Thames River in England used to stink and the water was black. Now it's so clean and crystal clear, that's because Britain has passed that period of great development. So, up to now, the environment is so good.

At present, China is vigorously developing its economy, and this pollution is inevitable. As for the PM2.5 index, it is mainly because there are too many cars and the exhaust emissions are enlarged, so there are too many fine particles to avoid.

The State Environmental Protection Department said in a statement. It's a bit unfair, though, to put all the blame on car exhaust. But it's true that car exhaust is a problem in metropolis. In particular, China's automobile exhaust is not up to the standard at all. A lot of car exhaust, actually also emitting black smoke, this kind of car on the road, that person has to take a breath, dizzy for a long time. Therefore, it is only reasonable to blame the car exhaust.

But if we say that, don't we have to live in this poisonous air all the time? Everyone, question.

The environmental protection department can't help it. This is the general trend of national development and a pain in the throes. They can't solve it either. If all of you don't use cars and all of your factories shut down, you'll be sure to get back to us. But is this going to work? There is a saying to describe the traffic in the imperial capital: I would rather buy a car and be stuck in the road than be exhausted by the bus.

This is enough to explain the mood of modern people. It's obviously impossible for you to ask people not to buy a car. This is absolutely not feasible. If the factory is shut down, that's even worse. If so many people don't work, there will be no food. If there is no food to eat, there will be great social unrest.

If you breathe poisonous air, it will bring harm in the future. If you have no food now and want to starve to death, what would you choose? I believe the vast majority of people will choose to start. After all, starve to death in the present, poison to death in the future. It's like that fable.

A man walking in the desert, thirsty to death, found a bottle of poison wine. If you drink it, your intestines will be rotten immediately. If you don't drink it, you will die of thirst immediately. And the man, he chose to drink. Always dead, at least for now. This is the famous idiom drinking poison to quench thirst.

There was a lot of discussion all over the country, but the result was no different. Of course, it also brings business opportunities to many enterprises across the country. This is not PM2.5 index is high, then we can develop air purifier, buy one at home, the air at home is not much better!

Therefore, many manufacturers all over the country took the opportunity to develop air purifiers. Air purifier capable of removing PM2.5 particles.

But just then, a voice called out - I can solve PM2.5!

Who is it? Who is so good that the country can't solve it. Can you solve it? Everyone doesn't have to look, guess, and know that if there is a person in China who can solve PM2.5, it's Lin Feng! Only he has the magic!
