Yu Jing has conducted haze surveys, which has led to the introduction of some authoritative institutions for air quality appraisal in Beijing. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As soon as she left Huaming Primary School, she contacted them. Wearing a breathing bubble, Yu Jing went straight to the Beijing City Air Quality Testing Institute.

The agency was set up just three years ago to detect air quality problems in the city.

Compared with some second- and third-tier cities with heavy smog, it is clear that as the capital of a country, its environmental problems can receive more attention.

Along the way, Yu Jing rarely felt very embarrassed.

A young lady, staring curiously at her head, and an inattentive one, almost crashed into a trash can.

Everywhere I went, 100% of the return rate was really stressful.

On the way, people asked her what was on her head from time to time, and some even recognized her identity and secretly followed and took pictures.

I don't know if there will be a website news report tomorrow.

"Well-known reporter Yu Jing has a strange bubble on his head, strolling through the streets of Beijing City"

However, when taking the crowded subway, Yu Jing had a deeper experience of the effect of this breathing bubble. Even with advanced ventilation equipment, if the carriage is crowded with passengers, the air in the subway will still become extremely poor, turbid and stagnant, and people with slightly poor physical fitness may even feel difficult to breathe.

When Yu Jing was working at CCTV in China, she almost went into shock in the dull air of the subway because of overwork.

However, the experience of this ride was completely opposite to her previous experience. Although the passengers around her were crowded, Yu Jing didn't feel a little uncomfortable, the air was still fresh and she breathed very smoothly.

The experience of the subway made her very impressed, and she even couldn't wait to know the test results.

Finally came to the Beijing City Air Quality Testing Institute, and Yu Jing did not breathe a sigh of relief.

The staff of the testing center were also full of doubts and curiosity about the bubbles on her head.

"I'm here to test the air in this bubble. Yu Jing pointed to the top of her head and said.

Wang Yihai is the head of the air quality testing institute and has dealt with Yu Jing many times.

For a well-known reporter like her, he dare not ignore it, and must do everything properly.

"No problem," Wang Yihai responded and called an internal phone to the staff of a testing laboratory, "Xiao Zhang, go to my office and collect an air sample." ”

The process of collection is not complicated.

The device easily passed through the round bubbles, and the person in charge of collecting the air specimen was a male staff member in his thirties. When he first saw the bubbles above Yu Jing's head, he was very surprised. But he was smart enough not to ask more, but according to Director Wang's instructions, he quickly collected the air sample and immediately returned to the laboratory for testing.

"Reporter Yu, is this the latest dust cover?" The air testing procedure is not responsible, and Yu Jing waited directly for the results at the testing center. While waiting, Wang Yihai curiously learned the ins and outs of this strange bubble.

Yu Jing explained the general situation to him.

The more Wang Yihai listened, the more surprised he became, until Yu Jing stopped talking, pondered for a moment, and said: "If this breathing bubble really has the effect of filtering and purifying the air, it is tantamount to the gospel of life for the residents living in the heavy haze area." ”

As the head of the Beijing City Air Quality Testing Institute, Wang Yihai is arguably the person who knows the city's air quality index best.

It is impossible if the heart is not anxious.

In recent years, fine particulate matter (PM2.5) has been a serious problem, and people have worried that these pollutants can directly enter the blood vessels and pose health hazards, but the harm caused by poor air is far more than that.

Treating air quality problems in an area requires a long and patient process.

Only by comprehensively changing the environment around the city and within the city can we truly achieve fundamental consideration.

However, before air pollution is completely eradicated, people living in cities can only endure the poisoning of polluted air in silence except to flee.

Therefore, when Wang Yihai heard Yu Jing's introduction and explanation, he couldn't help but remember the test results.

In the laboratory, Zhang Yi takes air samples from air bubbles and gives priority to various testing experiments.

Sulfur dioxide detection test, total suspended particulate matter detection, inhalable particulate matter detection, nitrogen oxide detection......

One test at a time, carried out in an orderly manner.

As time passed, each result was put together and ready to be sent to Wang Yihai's office.

"Zhang Yi," the lab colleagues looked at the data results, as if they saw the sun rising in the west, and their faces were full of surprise, "where was this air sample collected, is it the air in Beijing? The Air Pollution Index API value is only 18. ”

The national first-class air quality standard, the air pollution index API value is less than or equal to 50, indicating that the air quality is excellent, and meets the air quality requirements of nature reserves, scenic spots and other areas in need of special protection.

Another colleague who was transferred from other places pulled up a form from his computer and said in amazement: "Look, I have the air quality test report of Yichun in Northeast China. ”

Yichun Province of Heijiang Province is known as the forest capital, the forest coverage rate is as high as 83%, the forest is like the sea, the river water is clear, the air has a high concentration of negative oxygen ions, in one sentence, the air there is so fresh that it can pinch out the green.

The quality of the air has become a well-known sign of the city.

There are also manufacturers who fill air, which absorb the air from Yichun and sell it to cities with severe smog, ranging from 20 to 40 yuan per can.

If you can breathe this natural oxygen bar air every day, you will live for at least a few more years!

Zhang Yi carefully compared the two data, this just-released air quality test data, the indicators are completely comparable to the air in Yichun, and even some values, can still win.

Zhang Yi, who personally pulled out the air sample from the bubble above Yu Jing's head, couldn't wait to run to Director Wang's office immediately and ask what the bubble-like object above Yu Jing's head was.

Surrounded by the air full of nature, you can live with peace of mind even in heavily polluted cities.

Unbeknownst to others, the air sample came from a strange bubble.

By the time Zhang Yi told the others about the way he had just pumped out air, no matter how strange the appearance of the alien-like transparent bubbles on the top of his head was, everyone's hearts were eager.

"Xiao Zhang, hurry up and send the report back. Be sure to ask what happened to that bubble. The colleague in charge of sulfur dioxide testing said urgently.

"Yes, yes!" Another chubby middle-aged man patted Zhang Yi on the shoulder, his eyes looked like he was looking at his first love, and he looked at Zhang Yi's hair all over his body, "The health of my whole family will be handed over to you." ”

With the expectations of all colleagues in the laboratory, Zhang Yi went straight to Director Wang's office.

Knocking on the door and entering, Zhang Yi saw the transparent bubbles above Yu Jing's head again, and he was no longer funny and strange. He really wanted to put this bubble on his head and try the clean air comparable to the primeval forest.

"Xiao Zhang, what is the result of the report?" Wang Yihai asked seriously.

Zhang Yi did not leave, and took the opportunity to tell Director Wang and Yu Jing in detail about the results of the test.

Yu Jing and Director Wang listened quietly to Zhang Yi's story, and the more they listened, the brighter the light in their eyes became.
