What is Air Pollution?

Air pollution is the introductionofharmful materials intothe Earth's atmosphere, causingdamage, disease or death to humans,animals,vegetationorthe natural or built environment.

The ‘things’ that cause pollution arecalled pollutants.

Causes of Air Pollution

Air pollution can result from both human and natural actions.

Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity.

Pollution from natural occurrences are not very often.

Man-made air pollution:

Human activities that result in air pollution include:

1. Emissions from industries and manufacturing activities.

2. Burning of Fossil Fuels

3. Usage of Household and Farming Chemicals

Emissions from industries and manufacturing

activities

The Industry sector produces the goods and raw materials we use every day. The greenhouse gases emitted during industrial production are split into two categories:

1. direct emissions that are produced at the facility.

2. indirect emissions that occur off site, but are associated with the facility's use of energy.

2. Burning Fossil Fuels

Cars and heavy duty trucks, trains, shipping vessels and airplanes all burn lots of fossil fuels to work.

This is a major cause of pollution, and one that is very difficult to manage. This is because humans rely heavily on vehicles and engines for transporting people, good and services.

3. Household and Farming Chemicals

Crop dusting, fumigating homes, household cleaning products or painting supplies, over the counter insect/pest killers, fertilizer dust emit harmful chemicals into the air and cause pollution.

In many case, when we use these chemicals at home or offices with no or little ventilation, we may fall ill if we breathe them.
