What are the most significant sources of air pollution?
Air pollution is defined as the presence of dangerous elements, such as chemicals, particles, and gases in the air we breathe.
These pollutants can originate from both natural and human causes, such as dust storms, forest fires, and volcanic eruptions, as well as fossil fuel combustion, agriculture, and industrial operations.
The effects of air pollution on human health, the environment, and the climate include respiratory difficulties, heart illness, and environmental harm.

1. Fossil fuel combustion (power plants, vehicles, industries)
Combustion of fossil fuels emits pollutants such as
- Combustion of fossil fuels emits pollutants such as
- Nitrogen oxides (NOx)
- Sulphur dioxide (SO2)
- Particulate matter (PM)
- Volatile organic substances (VOCs)
- Heavy metals (lead, mercury)
These pollutants contribute to smog, acid rain, respiratory issues, and global warming. Power stations that burn coal, oil, or natural gas are important contributors to air pollution, as are gasoline- and diesel-powered vehicles (cars, trucks, trains, ships).
Industrial processes that utilise fossil fuels also emit air pollution.
2. Heating and cooking at home (burning wood, coal, gas)
Domestic heating and cooking has sources of pollutants like…
