2. What is
pollution
Pollution is the introduction of
contaminants into the natural
environment that cause adverse change.
Pollution can take the form of chemical
substances or energy, such as noise, heat,
or light.
Pollutants, the components of pollution,
can be either foreign substances/energies
or naturally occurring contaminants.
4. Air Pollution
Air pollution is a mixture of solid
particles and gases in the air.
Car emissions, chemicals from
factories, dust, pollen and mold
spores may be suspended as
particles.
Ozone, a gas, is a major part
of air pollution in cities. When
ozone forms air pollution, it's
also called smog.
Some air pollutants are
poisonous.
5. Water Pollution
Water pollution is the
contamination of water
bodies, usually as a result of
human activities.
Water bodies include for
example lakes, rivers,
oceans, aquifers and
groundwater.
Water pollution results when
contaminants are introduced
into the natural environment.
6. Land Pollution
Land pollution is a result of
dumping garbage, waste, and
other toxins making the land
contaminated or polluted.
The source of land pollution
comes from the human
element such as littering, and
waste that is washed ashore
from boats, oil rigs, and
sewage outlets.
7. Noice Pollution
Noise pollution, also known as
environmental noise or sound
pollution, is the propagation of
noise with ranging impacts on
the activity of human or animal
life, most of them harmful to a
degree.
The source of outdoor noise
worldwide is mainly caused by
machines, transport, and
propagation systems.
