It has a positive effect on PM2 5 governance

1. Control the source, strengthen the industrial dust control, the industrial production process is an important part of fine particulate matter, the prevention and control should start from the source, adopt a comprehensive treatment strategy, improve the existing dust removal technology and equipment, and strictly control the dust pollution caused by industrial production.

2. Improve the energy consumption structure, improve the efficiency of energy utilization, change the energy consumption structure, vigorously develop clean energy such as nuclear electricity, hydropower, biogas, solar energy, etc., and increase the use of clean energy, increase the proportion of renewable energy in the primary energy consumption structure, and reduce pollutant emissions caused by the combustion of fossil fuels such as coal and oil.

3. Control exhaust emissions, improve automobile emission standards, and control automobile exhaust emissions, especially before it was a motor vehicle fueled by diesel.

1. Definition: refers to particulate matter with an aerodynamic equivalent diameter of less than or equal to microns in ambient air, also known as fine particulate matter and particulate matter that can enter the lungs.

2. Characteristics: Its diameter is less than 1 20 of the thickness of human hair, and it can suspend lead in the air for a long time, and the higher its content (concentration) in the air, the more serious the air pollution. Although it is only a small component of the Earth's atmosphere, it has important effects on air quality and visibility.

The particle size is small, the specific surface area is large, the activity is strong, it is easy to carry toxic and harmful substances (such as heavy metals, microorganisms, etc.), and the front rock has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and atmospheric environmental quality.

2. PM10

1. Definition: PM10 is an inhalable particulate matter with an aerodynamic equivalent diameter of less than or equal to 10 microns, which refers to the general term for solid and liquid particulate matter floating in the air.

2. Features: PM10 can enter the upper respiratory tract, but some of it can be excreted through sputum, etc., and it will also be blocked by the villi inside the nasal cavity.

1. Cause airway obstruction or inflammation; 2. Defects caused by affecting fetal development; 3. It can make harmful substances such as pathogenic microorganisms, chemical pollutants, and oil fumes enter the body to cause cancer. 4. Particulate matter can enter the blood vessels through the exchange of qi and blood. 5. After the particles enter the human body to the alveoli, it will directly affect the ventilation function of the lungs, making the body easy to be in a state of hypoxia.

Also known as fine particulate matter, it refers to particulate matter in ambient air with an aerodynamic equivalent diameter of less than or equal to microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution.

The composition of particulate matter is complex and depends mainly on it**. There are two main types of natural sources and man-made sources, but the latter is more harmful. In academia, there are two types: primary aerosol and secondary aerosol.

The methods to prevent outdoor activities are: 1. Wearing a mask with real prevention is a very effective measure. 2. Try to minimize smoking or even non-smoking.

There is a large amount of smoke, which can be directly and indirectly harmful to the human body. 3. Don't exercise in the morning on foggy days, which is one of the important culprits causing foggy weather.

The most effective, straightforward, and self-effective way is to go out with a professional dust mask, because it refers to particles in the air with a diameter smaller than or equal to microns. Ordinary gauze masks or cotton masks can't protect against such small particles at all, just like you use a basket to hold water, can it be held?

The professional dust mask is made of non-woven material, and its structure is intricate and irregular, and it also has static electricity, even small particles cannot pass through.
