If you speak up occasionally, if you speak often, your relatives, friends, and colleagues think you're hypocritical After all, the health awareness of Chinese people is not strong, and they don't understand the harm of haze.
-
I chose to sell my house and flee to Yunnan.
-
It is forbidden to build high-rise buildings with more than 15 floors in the country, and leave enough space between buildings to solve the haze.
-
I just want to become an ecological refugee after I have money and live in a place with a good environment.
-
Caused by car exhaust, we all believe it.
-
It's as if it works to say that the voice is useful, so let's wear a mask.
-
Don't go out, don't make a sound, ask for the north wind at home.
-
Just wearing a mask and speaking out is useless.
-
I also wore a mask, I spoke up, but no one cared about my voice.
-
Be content, we are really far from the phenomenon in London, England, and if you speak out, it can't be changed immediately.
-
Of course, I spoke out, but I made all kinds of complaints, but it was useless, and the reply I got was that the leader was trying to find a way.
-
Bring a mask first, the smog problem is not something that can be solved overnight, after all, the economy is still developing, you can get all the chemical plants out of use.
-
If it were me, I would still choose to speak out, after all, wearing a mask can't solve the problem fundamentally, and I can't wear ten layers of masks.
-
I still didn't wear a mask, after all, I have found a way to solve it now, and the result is a little, but it's just a little.
-
I'm afraid I can only wear a mask, I really don't know what way to speak out, ordinary citizens can go to the people's congress to reflect their opinions.
-
Obediently put on a mask, how loud can you be when you make a sound, and you can't change the status quo of smog if you bring a microphone to shout.
-
Personally, I think I'm already trying to improve, so let's bring a few more masks first, bear with it a little, and I believe it will be fine soon.

Haze is a combination of fog and haze, but the difference between fog and haze is very big, the aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment, and fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the ground.
Haze weather is a state of air pollution, haze is a general expression of the excessive content of various suspended solids in the atmosphere, especially the aerodynamic equivalent of particulate matter with a diameter of less than or equal to microns) is considered to be the culprit of haze weather. With the deterioration of air quality, the phenomenon of haze weather has increased, and the harm has increased. In many parts of China, haze weather phenomena are combined with fog as a warning and forecast of hazardous weather, which is collectively referred to as haze weather.
When going out in haze weather, you need to wear a professional mask, which can effectively avoid the harm of haze. In GB2626-2006, the state clearly stipulates that the dustproof efficiency of dust masks is divided into three levels: KN90, KN95 and KN100, among which KN100 dust masks can protect against ultra-fine dust and can effectively protect against haze hazards.

1. It works. But there are many types of masks, and wearing different masks has different protective effects.
2. As a professional anti-virus and dust-proof mask, N95 does have a good filtration function, but its density is high, and it is easy to make people feel uncomfortable when worn for a long time, especially for patients with cardiovascular diseases and patients in the onset of respiratory diseases.
3. The ordinary masks on the market with beautiful shapes, these masks have a certain filtering effect on large particles of dust, but they are also useless for small particles.
4. Paper medical masks, although not beautiful, achieve the optimal configuration of air permeability and filtration. .
-
In hazy weather, ordinary people are more suitable to wear KN90 masks. The mask has a 90% ability to capture particles smaller than microns, then it is KN90, and if the capture capacity is 95%, it is N95. For this kind of haze weather, ordinary cotton masks basically have no protective effect; Although N95 can filter 95%, it is tightly sealed and has poor air permeability.
For special populations, such as children, the elderly, people with respiratory diseases and cardiovascular diseases, it is even more prudent to choose KN90 masks with exhalation valves. The average person wears it and breathes more smoothly, which has no impact on normal work and life. In addition, the sterilization grade and ordinary grade marked on the outer packaging of the mask are only the cleanliness of the mask itself, and have nothing to do with the filtration effect.
-
If it is a dust-proof Zen hall or anti-haze, it is still a KN100 level mask with a good protective effect. It is recommended to choose a high-grade silicone material for the mask. It is recommended to choose a double-piece design for the filter, the filter is double-sided or pleated, the area is large, and the breathing is relatively smooth.
At present, due to the improvement of the level of mechanization, the relatively high dust concentration in the working environment, the wrong choice of masks, excessive attention, ignoring the protective effect, quality, comfort and service life of masks, are easy to lead to the selection of low-grade and counterfeit products, resulting in occupational injuries. It is recommended to combine the GB2626-2006 standard to scientifically select dust masks to effectively prevent respiratory injuries.
5 Now many enterprises and individuals in order to effectively prevent the occurrence of pneumoconiosis, gradually choose KN100 grade products, due to the new product technology leading, good protection effect, respiratory protection as smooth, especially some masks using high-grade silicone material, the use of about one yuan per day, compared with the past, improve work efficiency, reduce safety protection expenditure.
In this environment, most of the dust is in an ultra-fine state, permeating the air noisy and medium, working in this environment, if the respiratory protection is improper, it is very easy to suffer from pneumoconiosis. Because pneumoconiosis is characterized by secondary and high mortality.
The protective effect of dust masks mainly depends on two aspects. One is the tightness of the mask and the face. The second is the protection level of the filter cotton.
Pneumoconiosis is an occupational disease that causes fibrosis of lung tissues due to long-term inhalation of dust. The lesion progresses, causing the disability level of pneumoconiosis to rise until death.

If you want to prevent smog indoors, you can install a fresh air system. It can realize 24 hours without opening the window to deliver fresh air to the room, and at the same time discharge the dirty air in the room to ensure the freshness and cleanliness of the indoor air.
-
Go out less and exercise more on weekdays to stay away from smog areas.
-
At present, there are very professional dust-proof, anti-haze and dust-proof masks for a long time.
According to the GB2626-2006 standard, dust masks are divided into disposable and compound half masks and full face masks. According to the protection efficiency of dust, it is divided into KN100, KN95 and KN90.
The protective effect of dust masks mainly depends on 2 major aspects. One is the air leakage rate of the mask, and the other is the protection level of the filter. Dust mask selection essentials.
1. Buy a dust mask that has passed the national standard certification of "Self-priming Filtering Anti-particulate Respirator".
2. According to the national standard, masks are divided into three levels: KN100, KN95 and KN90. The value represents the protection efficiency against ultrafine dust. The bigger, the better.
3. Choose a breathing smooth-breathing dust mask.
4. Choose a dust mask in different sizes. Good sealing.
5. Choose a dust mask made of silicone as much as possible. Soft and comfortable.
Haze is caused by the excessive content of particulate matter (particulate matter) in the air, and most of the residues emitted through combustion in the process of daily power generation, industrial production, automobile exhaust emissions, etc., mostly contain fine particulate matter, which is a general term for solid particles or droplets with a diameter of less than or equal to microns in the air, which can enter the lungs with breathing, so it is also called particulate matter that can enter the lungs.
This kind of weather can be said to be a natural meteorological cause since ancient times, and there are also pollution emission reasons. Visibility is affected by a large number of very fine dust or smoke particles floating in the air. But don't be too afraid. >>>More
Pay attention to the pollution situation: Always pay attention to the city's air pollution monitoring data, and be alert to high-pollution weather and time periods. >>>More
I think it can be mitigated a bit。Although this may not sound very reliable, for the sake of our health, we still have to believe it. >>>More
What are the measures to control smog?
The measures to control haze mainly include: 1. Accelerate the adjustment of energy structure. Great efforts should be made to do a good job in the efficient and clean use of coal. >>>More
