Air Pollution (Cause and Effects)

• Air pollution is caused by solid and liquid particles and certain gases that are suspended
in the air.

• These particles and gases can come from car and truck exhaust, factories, dust, pollen,
mould spores, volcanoes and wildfires.

• Certain gases in the atmosphere can cause air pollution. For example, in cities, a gas
called ozone is a major cause of air pollution.

• Ozone is also a greenhouse gas that can be both good and bad for our environment. It
all depends where it is in Earth’s atmosphere.

• Long-term health effects from air pollution include heart disease, lung cancer, and
respiratory diseases.

• Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver,
and other organs.

What makes air dirty?
