What are the main causes of urban air pollution?

Urban Air Pollution Sources

• Transportation. The use of private vehicles (particularly older, diesel models) is the major source of urban air pollution.
• Domestic use of fossil fuels.
• Industrialization.
• Power generation.
• Combustion and agriculture.
• Beauty Products.
• Ozone (O₃)
• Particulate matter (PM10, PM2.5)

How do we pollute the air?

Carbon dioxide is emitted into the atmosphere by burning fossil fuels (coal, gasoline, and natural gas). Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide.

What are the main pollutants of the urban areas?

They are major sources of both local urban pollutants, such as oxides of nitrogen, hydrocarbons, and carbon monoxide, and global greenhouse emissions, like.CO2 (They are a major source of noise pollution as well.)

What is a major source of pollution in rural areas?

Is country air better than city air?
