Chapter 4911 PM2.5

The air in China is very bad!

This news soon appeared in the international media. Watermark Advertising Test Watermark Advertising Test As for Lin Feng's three glasses of wine, Donald asked the American escorts not to tell anyone about it. No one in China dared to say it, so the outside world didn't know about it at all. The focus of the outside world is on the issue of poor air quality in China.

The first country the President of the United States chose to visit was China. Well, he ended up spending seven days bathing in yellow sand. This is wonderful! Here in the United States, leather shoes don't get polished for a month and they are still shiny. As a result, when I arrived in China, my newly polished leather shoes became dirty when I went out.

Freshly washed clothes, go out and get dirty. My freshly styled hair was messed up when I went out! Once it goes out, it's just a layer of dust. If you stand outside for a while and then come in, you will feel uncomfortable if you don't take a shower.

Will the Olympics be held in this kind of weather? How can athletes compete in such bad weather? This game is suicide! This is completely murdering the lives of athletes! Holding the Olympics in this kind of weather is a life-threatening exercise!

All kinds of opinions are overwhelming at this time. And this makes China feel embarrassed and ashamed. Looking at the blue sky and white clouds abroad and the yellow sand sky in China, one is living in heaven and the other is living in hell.

But at this time, something even more desperate came out. That is what changed the perception of Chinese people - the pm2.5 index.

The U.S. Embassy announced that the PM2.5 index in Beijing is as high as 380!

What is this pm2.5? Everyone was puzzled for a while, and what is this 380!

Immediately, some netizens found an explanation about the pm2.5 index on Baidu Yahoo.

The so-called pm2.5. It refers to particles in ambient air with an aerodynamic equivalent diameter of less than or equal to 2.5 microns. It can remain suspended in the air for a longer period of time. The higher its concentration in the air. It means the air pollution is getting worse. Although pm2.5 is only a small component of the earth's atmosphere, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, a large area, and strong activity. It is easy to carry toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact on human health and atmospheric environment quality. The chemical components of fine particulate matter mainly include organic carbon (), elemental carbon (), nitrate, sulfate, ammonium salt, sodium salt (na+), etc.

Generally speaking, such fine particles are naturally produced when volcanic eruptions emit large amounts of volcanic ash into the atmosphere. Forest fires or exposed coal fires and dust storms all produce large amounts of fine particles. If people are nearby and absorbed into the body, they will feel very uncomfortable. But this is just natural, it is slightly better.

The real trouble is the tiny particles caused by human activities. Such as smoke and dust emitted from various industrial processes such as power generation, metallurgy, petroleum, chemistry, textile printing and dyeing, heating, and cooking when burning coal, gas, or fuel oil. The flow source is mainly the exhaust gas emitted into the atmosphere when various types of vehicles use fuel during operation. These fine particles are generated from the chemical industry, so the fine particles they produce are extremely harmful to the human body.

This is not as simple as choking people. After these fine particles are absorbed into the body, you eat cow blood. It can't be excreted, and it's useless no matter how much you eat. It will always be adsorbed in your body, in your lungs, and then slowly absorbed and digested by your body, and finally turn into cancer. At that point, you're in big trouble. As for this kind of cancer, it can be said that you don’t know the cause of the disease at all, and there is no way to treat it.

And chemotherapy didn’t work. Because the root cause is in your body and cannot be solved by chemotherapy. The end result is to slowly die from pain.

Everyone was shocked when they saw these explanations. So, this index of 380,

How high is it?

Of course, Baidu Encyclopedia has an explanation.

Tokyo, Japan, is a bustling metropolis, and its pm2.5 index averages around 30. This is Tokyo! Even during peak hours after get off work, the PM2.5 index is capped at 50. And the 380 here is almost ten times that.

Looking at London, pm2.5,40 is a little higher than Tokyo, but far lower than China. In New York, the United States, the pm2.5 index is higher, about 70, but even if it is 70, it is far from what China can compare with.

As for countries like Germany and France, not to mention, they are basically the same as Tokyo, Japan. And if it is not a prosperous metropolis, then there is no need to talk about the index. Basically, just around 10. This index is completely disappointing to the Chinese people.

10, which is a 38-fold difference. This gap is too big!

Is this data accurate? It's clear that the vast majority of netizens believe its data is accurate. Because this is announced by the US Embassy. In this kind of matter, the U.S. Embassy will never maliciously slander China. People believe that the U.S. Embassy cannot do this kind of thing. After all, in the hearts of ordinary people, the United States still has some integrity.

But if this is the case, then aren’t we living in a big source of pollution? If this continues, won’t everyone of us get cancer? Will die in pain! All the people panicked. Almost immediately, the streets and alleys were full of masks. A must-have for everyone when traveling is a mask. There is no way, this is so powerful, how can they not wear masks?

Of course, this is a little comforting for people who don't live in the imperial capital. The pollution index in the imperial capital is high, but other areas should be fine. They shouldn't worry. But then, 'Baidu Yahoo' announced the pm2.5 index across the country, and once this index was announced, it shocked the whole country.

In all regions of the country, the north is basically 200+, and the south is slightly better, but it is also more than 100. This number, compared with foreign countries, is obviously not up to standard. The only place in the country with better air quality is Hainan Island and some mountainous areas in Yunnan. The air index in these places is similar to that in foreign countries. Of course, it is similar, mainly compared with New York. Compared with Japan, it is still incomparable.

In China, no matter how low the air index is, it is above 50. If you want to reach 10, it is impossible except for the primeval forest, such as Shennongjia.

Shock! In addition to shock! Still shock! No one thought that we were living in poisonous gas. In addition to everyone's slight doubts about the data released by 'Baidu Yahoo', everyone is looking at the country, wanting to see how the country can solve it.

But in fact, the country cannot solve it. If society wants to develop, pollution is inevitable. For example, in developed countries abroad, pollution comes first and then governance. For example, the Thames River in the UK used to be smelly and the water was black. Now it is so clean and clear, because the UK has passed that period of great development. Therefore, the environment is so good now.

China is currently vigorously developing its economy, and this pollution is also inevitable. As for the PM2.5 index, it is mainly because there are more cars and large exhaust emissions, so there are many fine particles and it is unavoidable.

The National Environmental Protection Department spoke. Although it is a little unfair to put all the blame on car exhaust. But it is true that in big cities, car exhaust is indeed a problem. Especially in China, car exhaust does not meet the standards at all. Many car exhausts are still billowing black smoke. If a person breathes a breath of this kind of car on the road, he will be dizzy for a long time. Therefore, it is barely reasonable to blame it on car exhaust.

But if we say so, don’t we have to live in this toxic air all the time? Everyone has questions.

The environmental protection department can't do anything. This is the general trend of national development and a pain. They can't solve it either. If all of you don't use cars and all factories stop working, then you will definitely have blue skies and white clouds. But will this work? Isn't there a saying that describes the traffic in the imperial capital: I would rather buy a car and get stuck in traffic than squeeze on a bus and die of exhaustion.

This is enough to explain the mood of modern people. It is obviously not feasible to ask people not to buy cars. This is absolutely not feasible. If the factory stops working, it will be even worse. If so many people don't work, they will have no food to eat. Without food, society will inevitably be in turmoil.

Breathing toxic air will bring harm in the future, and having no food to eat now and starving to death, what will you choose? I believe that most people will choose to work. After all, starving to death is in front of you, and poisoning to death is in the future. This is just like that fable.

A man was walking in the desert, dying of thirst, and found a bottle of poisoned wine. If he drank it, his intestines would be ruptured immediately. If he didn't drink it, he would die of thirst immediately. And that person chose to drink it. It's always a death, at least it's a little more comfortable now. This is the famous idiom - drinking poison to quench thirst.

The whole country is talking about it, but the result is no different. Of course, this also brings business opportunities to many companies across the country. Isn't the pm2.5 index high? Then we can develop an air purifier. Buy one and put it at home. Wouldn't the air at home be much better!

Therefore, many manufacturers across the country have spotted the business opportunity and immediately stepped up to develop air purifiers. Air purifiers that can remove pm2.5 particles.

But at this moment, a voice shouted - I can solve pm2.5!

Who is it? Who is so awesome that the country can't solve it, can you solve it? Everyone doesn't need to look or guess, and they know that if there is someone in China who can solve pm2.5, it must be Lin Feng! Only he has this magic! (To be continued...)
