The document defines air pollution as gases or dust in harmful amounts that can affect human health or the environment. It identifies the three main sources of air pollution as primary pollutants emitted directly into the air, secondary pollutants created by chemical reactions of primary pollutants, and examples include car exhaust and coal combustion. Air pollution can cause both short-term effects like respiratory issues and long-term health impacts such as cancer, heart disease, and neurological effects. It also damages plant and animal environments by direct contact with pollutants or indirectly through impacts on resources.

2.  The definition of air pollution.
 The three main sources of Air pollution.
 The effect of air pollution.

3. Air pollution occurs when the air contains gases, dust, in
harmful amounts. That is, amounts which could be
harmful to the health or comfort of humans and
animals or which could cause damage to plants and
materials.
The substances that cause air pollution are called
pollutants. Pollutants that are pumped into our
atmosphere and directly pollute the air are called
primary pollutants. Primary pollutant examples
include carbon monoxide from car exhausts and
sulfur dioxide from the combustion of coal.
Further pollution can arise if primary pollutants in the
atmosphere undergo chemical reactions. The
resulting compounds are called secondary
pollutants. Photochemical smog is an example of this.

6.  Air pollution can affect our health in many ways with both short-
term and long-term effects.
 short-term effects include irritation to the eyes, nose and throat,
and upper respiratory infections such as bronchitis and
pneumonia. Other symptoms can include headaches, nausea,
and allergic reactions. Short-term air pollution can aggravate
the medical conditions of individuals with asthma and
emphysema.
 Long-term health effects can include chronic respiratory disease,
lung cancer, heart disease, and even damage to the brain,
nerves, liver, or kidneys. Continual exposure to air pollution
affects the lungs of growing children and may aggravate or
complicate medical conditions in the elderly. It is estimated that
half a million people die prematurely every year in the United
States as a result of smoking cigarettes.

7.  Air pollution does not only damage the air;
it also damages environments on Earth’s
surface and their
inhabitants. plants and animals are harmed
by air pollution. Sometimes it is the
pollutants themselves that cause damage.
Other times pollutants combine and
change the resources that plants and
animals depend upon such as water, soil,
and nutrients. Read on to learn more about
the ways that air pollutants can damage
environments and the living things within
them.
