What are the hazards of air pollution?

At first, the harm of air pollution experienced by human beings was mainly harmful to human health, and later, various hazards to industrial and agricultural production and adverse effects on weather and climate were gradually discovered. The impact of air pollution on human body is firstly uncomfortable, then the physiological reversible reaction, and then the acute harmful symptoms. The harm of air pollution to people can be roughly divided into three types: acute poisoning, chronic poisoning and carcinogenesis.

The hazards of air pollution are:

1. After air pollution, due to the different sources, properties, concentrations and duration of pollutants, it will cause different hazards to human body, such as acute poisoning, chronic poisoning and carcinogenesis.

2. Air pollution is very harmful to industrial and agricultural production, which will affect economic development and cause a lot of loss of manpower, material resources and financial resources.

3. Harmful factors caused by air pollution, such as sulfur dioxide, nitrogen oxides and carbon monoxide, can cause diseases such as bronchitis.

Air pollutants can also affect weather and climate. Particulate matter will reduce atmospheric visibility and reduce the amount of solar radiation reaching the ground.

5. When the concentration of air pollutants is high, it will cause acute damage to plants, causing spots on the surface of plant leaves, causing branches and leaves to wither and fall off.

What is the main source of air pollution?

Air pollutants are produced by natural factors and human factors.

1. Natural factors include volcanic eruption: the emission of particles such as hydrogen sulfide (H2S), carbon dioxide (CO2), cobalt element CO, hydrogen fluoride (HF), sulfur dioxide SO2 and volcanic ash.

2. Nitrogen dioxide forest fire: releasing cobalt (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), etc.

3. Natural dust: sandstorm, soil dust, etc.

4. Human factors include fuel combustion: the combustion process of coal, oil and natural gas is an important source of transporting pollutants to the atmosphere.

5. Emissions from industrial production processes: such as hydrogen sulfide, carbon dioxide, sulfur dioxide and nitrogen oxides emitted by petrochemical enterprises.

To sum up, polluted air will seriously affect people's health, and air pollution will also reduce people's immune function and reduce people's resistance, thus inducing or aggravating many other diseases. Air pollution is also very harmful to agriculture, forestry and animal husbandry.

Legal basis:

People's Republic of China (PRC) Air Pollution Prevention and Control Law

Article 6

The state encourages and supports scientific and technological research on the prevention and control of air pollution, carries out analysis on the sources and changing trends of air pollution, popularizes advanced and applicable air pollution prevention technologies and equipment, promotes the transformation of scientific and technological achievements, and gives full play to the supporting role of science and technology in the prevention and control of air pollution.

Article 7

Enterprises, institutions and other producers and operators shall take effective measures to prevent and reduce air pollution, and shall be liable for the damage caused according to law.

Citizens should enhance their awareness of atmospheric environmental protection, adopt a low-carbon and frugal lifestyle, and consciously fulfill their obligations of atmospheric environmental protection.
