What are the air pollution control measures?

The air pollution control measures are as follows:

1. Reduce pollutant emissions;

2. Strictly control the new production capacity of industries with high energy consumption and high pollution;

3. Vigorously promote cleaner production;

4. Accelerate the adjustment of energy structure and increase the supply of clean energy such as natural gas and coal-based methane;

5. Strengthen the constraints of energy conservation and environmental protection indicators.

The harm of air pollution mainly includes the following aspects:

1. Harm to human health: clean air is indispensable for human survival, and polluted air will directly threaten our health. The harm of air pollution to human beings is various, mainly manifested in respiratory diseases and physiological dysfunction, as well as irritation of mucous membranes such as eyes and nose, which may lead to acute or chronic poisoning and even life-threatening;

2. Harm to plants: Air pollutants, especially sulfur dioxide and fluoride, are very harmful to plants, and high concentrations of pollutants will cause acute harm to plants, causing leaf spots or leaves to wither and fall off; Low concentrations of pollutants will cause chronic harm to plants, make the leaves green or affect their physiological functions, and eventually lead to the decline of plant yield and deterioration of quality;

3. Impact on weather and climate: The most direct impact objects of air pollutants are weather and climate, and its impact mainly includes the following aspects:

(1) Reduce the amount of solar radiation reaching the ground: A large number of air pollutants enter the atmosphere, which will make the air very turbid and form smog, etc., blocking the sun, reducing the amount of solar radiation reaching the ground, which will affect the growth and development of plants and people;

(2) Increase atmospheric precipitation: many particles discharged from large industrial cities have the function of condensation nuclei of water vapor, which will combine with water vapor in the air to form rainfall; In the downwind areas of some large industrial cities, the precipitation will be more;

(3) Acid rain: air pollutants produced by industry often contain sulfur dioxide. When it rains, sulfur dioxide will be oxidized to form sulfuric acid, which will lead to the fall of acid rain. The corrosion of sulfuric acid rain will destroy large areas of forests and crops, break paper products, textiles and leather products, pollute buildings, and deteriorate metal antirust coatings, which will reduce the protection.

(4) Increasing the atmospheric temperature: In cities with serious industrialization, a large amount of waste heat is discharged into the atmosphere, which will make the temperature of the air near the ground higher than that in the surrounding suburbs, which is the so-called "heat island effect";

(5) Impact on the global climate: A major impact of air pollution is the greenhouse effect. Gases such as carbon dioxide, methane and freon are continuously discharged into the atmosphere. Through heat preservation, the global climate is warming, which brings risks such as iceberg melting, sea level rising and coastal cities being submerged. Under the influence of the greenhouse effect, the average annual temperature has increased in recent decades, and winter has become less cold than before. If greenhouse gases are not controlled,

to sum up, air pollution refers to the phenomenon that the content of some substances in the atmosphere reaches a harmful level, which destroys the ecological system and the conditions for the normal survival and development of human beings and causes harm to people or things.

Legal basis:

Article 2 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution

To prevent and control air pollution, we should aim at improving the quality of the atmospheric environment, adhere to source control, plan first, change the mode of economic development, optimize the industrial structure and layout, and adjust the energy structure.

to prevent and control air pollution, we should strengthen the comprehensive prevention and control of air pollution such as coal burning, industry, motor vehicles and boats, dust and agriculture, carry out joint prevention and control of regional air pollution, and implement coordinated control of atmospheric pollutants such as particulate matter, sulfur dioxide, nitrogen oxides, volatile organic compounds, ammonia and greenhouse gases.
