Now people seem to be paying more and more attention to PM2 5 solutions

It refers to particulate matter in the atmosphere with a diameter of less than or equal to microns, also known as particulate matter that can enter the lungs, and the main components are elemental carbon, organic carbon compounds, sulfate, nitrate, and ammonium salts. Other common components include sodium, magnesium, calcium, aluminum, iron and other metal elements rich in the crust, as well as lead, zinc, arsenic, cadmium, copper and other heavy metal elements mainly derived from human pollution, which are harmful substances with a high rate of pathogenicity and carcinogenicity. The Gunai fresh air system has an efficient SHF multi-layer filtration and purification treatment system, with an effective filtration rate of up to high, which is in a leading position in the fresh air industry, comprehensively solving the problem of indoor intrusion and defending the air quality of the room.

Other common components, including sodium, magnesium, calcium, aluminum, iron and other abundant metal elements in the earth's crust, mainly come from human pollution with heavy metals such as lead, zinc, arsenic, cadmium, copper, harmful substances with a high rate of pathogenicity and carcinogenicity. The effective filtration rate of the Gunai fresh air system has reached the effective filtration rate of the high-efficiency SHF multi-layer filtration and purification system, which is in a leading position in the industry, and a full range of solutions to the problem of indoor intrusion and the protection of indoor air quality.

If you're also in Beijing, it's impossible not to pay attention to the air when you go out and smell the air.

Now the air pollution is too bad! To pay attention is to pay attention to your own life!

Here are some ways to destroy the pollution that can be fed:

1.Wear a mask: Choose a sedan rock mask with good filtration, such as an N95 mask, to reduce the amount of inhalation.

2.Air purifiers: Using an air purifier indoors can filter out particulate matter in the air and improve indoor air quality.

3.Indoor ventilation: Keeping the room ventilated can reduce the indoor concentration to outdoor levels.

4.Reduce outdoor activities: Try to avoid outdoor activities in heavily polluted weather.

5.Increase indoor greenery: Adding greenery indoors can absorb particulate matter from the air.

6.Reduce driving: Minimize driving, choose public transportation or cycling to reduce air quality pollution from vehicle exhaust.

7.Pay attention to your diet: Eat more foods containing vitamins C and E to enhance the body's immunity and reduce harm to the body.

1. Carcinogenic.

The International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) has released a report identifying air pollution as a common and major environmental carcinogen for the first time.

2. Harm organs.

Long-term exposure to particles can lead to cardiovascular and respiratory diseases, as well as lung cancer. When concentrations in the air are higher than 10 g m for a long time, the risk of death increases. For every 10 g m increase in concentration, the overall risk of death increased by 4%, the risk of death from heart and lung disease increased by 6%, and the risk of death from lung cancer increased by 8%.

3. Affect the environment and climate.

It can affect cloud formation and rainfall processes, and indirectly affect climate change. In addition to the salt in seawater, fine particulate matter is also an important source of condensation nuclei of rainwater in the atmosphere.

Summary. It refers to particulate matter in the atmosphere with a diameter of less than or equal to microns, also known as particulate matter that can enter the lungs (there is no standard Chinese name). Although it is only a small component of the Earth's atmosphere, it has important implications for air quality and visibility.

The particle size is small, rich in a large number of toxic and harmful substances, and the residence time in the atmosphere is long, and the transportation distance is long, so it has a greater impact on human health and atmospheric environmental quality. As a special reminder, masks do not work because the diameter of the particles is too small, and only gas masks can effectively protect them.

The particle size is small, rich in a large number of toxic and harmful substances, and the residence time in the atmosphere is long, and the transportation distance is long, so it has a greater impact on the health of the human body and the quality of the atmospheric environment.

As a special reminder, masks do not work because the diameter of the particles is too small, and only anti-bridge early gas masks can effectively protect them.

The increase of these substances is closely related to human activities.

What kind of university should Jinan Vocational College be?

Hello. What would you like to ask about it?

Is it a university, exactly?

The profound school-running heritage has yielded fruitful results. The school has successively won the National Advanced Unit of Innovation and Entrepreneurship Education in Higher Vocational Colleges, the National Demonstration School of Employment Competitiveness of Vocational Colleges, the National Teacher Training Base for Professional Backbone Teachers of Higher Vocational Schools, the Presidium Unit of the National Higher Vocational Education "School-Enterprise Integration" Innovation Alliance, the Demonstration College of School-Enterprise Integration in Shandong Province, the National Demonstration Unit of Economical Public Institutions, the Excellent University of Moral Education in Linglian Province, the Civilized Campus of Colleges and Universities in Shandong Province, and the Advanced Unit of Ideological and Political Education in Colleges and Universities in Shandong ProvinceIt has been awarded a series of honorary titles such as Shandong Province Economical University Construction Demonstration Unit and National Advanced Unit of Vocational Education, and has been rated as a provincial civilized unit for 10 consecutive years.

Here is a brief introduction to the school.

Specifically, you have to see what you like and whether there is a major that suits you.

At present, there are many primary and secondary school students who bring mobile phones to school, what do you think about this?

Many schools do not allow mobile phones, which is generally rare, and if you do, you are playful.

What's the biggest difficulty you've ever faced? How did you deal with and solve it?

Hello, what I need is a question about you.

And not about myself.

Is there anything else you would like to ask?

What are the perceptions of students who are absent from school?

This has the student's own ideas, and the school's own handling rules, are you a teacher?

Parents will need to be contacted to deal with the issue.

Vegetables **** more than meat, how to see this phenomenon?

Grow your own. Open your own field.

You don't have to buy it.

Why is the relationship between people in society cold?

Because of the interests.

Refers to particulate matter that can enter the lungs, the landlord can pay attention to the weather forecast of large cities such as Beijing and Shanghai, the index of the inhalable particulate matter forecast is very low, but the weather is indeed gray, this is because of the particulate matter that can enter the lungs). The recent news always mentions it, because the people's awareness has improved, the actual weather conditions are different from the forecast, China currently only has detailed rules on PM10 (inhalable particulate matter), and there are still gaps, there is no unified monitoring rules, only the local monitoring guidelines formulated by various localities, not uniform. Recently, the Ministry of Environmental Protection is preparing to develop monitoring guidelines that will be piloted in large and medium-sized cities such as Beijing and Harm next year, so his appearance rate is very high.

Closely related to us, the smaller the diameter of the particulate matter, the deeper the part that enters the human respiratory tract, the greater the harm to the human body, is the diameter of the particle equal to or less than microns, the harm to the human body is great!

Deadly killer: Particulate matter that can enter the lungs.

The smaller the diameter of the particulate matter, the deeper it enters the human respiratory tract and the greater the harm to the human body. However, particulate matter that can enter the lungs is too small in diameter, and the impact on human health is much greater than that of inhalable particulate matter. Data published by the World Health Organization also suggests an increased risk of death.

Meteorologists and medical experts believe that haze caused by fine particulate matter is even more harmful to human health than sandstorms. Particulate matter with a particle size of more than 10 microns will be blocked from the human nose;Particulate matter with a particle size between microns and 10 microns can enter the upper respiratory tract, but some of it can be excreted through sputum, etc., and the harm to human health is relatively smallFine particles with a particle size of less than microns, the diameter of which is equivalent to 1 10 the size of a human hair, will enter the bronchi after being inhaled into the human body, interfering with the gas exchange in the lungs, causing diseases including asthma, bronchitis and cardiovascular diseases. These particles can also enter the bloodstream through the bronchial tubes and alveoli, and the harmful gases and heavy metals in them are dissolved in the blood, which is more harmful to human health.

In the European Union, particulate matter that can enter the lungs reduces the average life expectancy of people by one month. It can also be a vector for viruses and bacteria, contributing to the spread of respiratory infections.

Prevention and control measures, it is recommended to use an air purifier, which can effectively purify the air, here it is recommended that the landlord use the air purifier of Lanshier, Lanshier can effectively kill particles as small as microns, not a problem at all, and it is fair, beautiful and fashionable, using electrostatic adsorption technology, no need to replace the filter, which can save a lot of money!
