Ten causes of air pollution

Industrial emissions, traffic emissions, burning fossil fuels, agricultural activities, construction, domestic waste incineration, fireworks, weather conditions, fires, human activities.

1, industrial emission: industrial production is one of the main sources of air pollution. Many factories and enterprises emit a lot of waste gas and harmful substances, which will pollute the air and endanger human health and the environment.

2. Traffic emission: Traffic is one of the main sources of urban air pollution. Cars, motorcycles and public transport all emit waste gas and harmful substances, which will pollute the air and do harm to human health and the environment.

3. Burning fossil fuels: The burning of fossil fuels such as coal, oil and natural gas will produce a lot of harmful substances such as carbon dioxide, sulfur dioxide and nitrogen oxides, which will pollute the air.

4. Agricultural activities: Agricultural activities are also an important cause of air pollution. Fertilizers and pesticides used in agricultural production will produce harmful gases and particles and pollute the air.

5. Building construction: The materials and mechanical equipment used in building construction will produce a lot of dust and waste gas, polluting the air.

6. Incineration of domestic waste: Domestic waste contains a lot of organic matter, plastics and other substances. After incineration, it will produce a lot of carbon dioxide and harmful substances, polluting the air.

7. Setting off fireworks and firecrackers: Setting off fireworks and firecrackers will produce a lot of harmful gases and particles, polluting the air.

8. Meteorological conditions: Meteorological conditions will also affect air quality. For example, weather conditions such as high temperature, low humidity and weak wind will aggravate air pollution.

9. Fire: Fire will produce a lot of harmful gases and particles and pollute the air.

10. Human activities: Human activities are also an important cause of air pollution. For example, smoking, barbecue and painting will produce a lot of harmful substances and pollute the air.
