Question

Name some human activities responsible for air pollution?

Answer 1

Air pollution:

• Human activities related to the industry, the burning of fossil fuels in automobiles and power plants, etc. add undesired components to the natural air, which results in air pollution.
• Some common air pollutants which pollute the air are gases like, carbon dioxide(${\mathrm{CO}}_2$), nitrogen dioxide(${\mathrm{NO}}_2$), carbon monoxide($\mathrm{CO}$), etc.

The human activities that lead to air pollution:-

Burning of fossil fuels:

• Sulphur dioxide(${\mathrm{SO}}_2$) released by the burning of fossil fuels like coal, and petroleum is the major cause of air pollution.
• Gases emitted from vehicles including trucks, jeeps, cars, trains, and airplanes cause an immense amount of pollution

Agricultural activities:

• Use of insecticides, pesticides, and fertilizers in agricultural activities releases harmful chemicals into the air and can also cause water pollution

Exhaust from factories and industries:

• Manufacturing industries release a large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air thereby depleting the quality of air.
• Petroleum refineries release hydrocarbons and various other chemicals that cause air pollution.

Mining operations:

• Mining is a process wherein minerals below the earth are extracted.
• During this process dust and chemicals are released into the air causing massive air pollution.
