Air Contamination
What kind of contamination is it?
Air pollution can be contaminants that exist as a gas mixed
with the air or that are attached to or make up particles
suspended in the air.
How did it get there?
Air pollution results when gases or particles containing
hazardous substances are released to the air. There are
many sources of air pollution including, emissions from
smokestacks and landfills, explosions and fires, automobile
exhaust, factory equipment leaks, and commercial products,
such as paints or household cleaners. Liquid hazardous substances
can cause air pollution when they are exposed to air and
evaporate. Contaminants in surface soil can contribute to
air pollution if the soil becomes airborne in the wind.
How does it hurt animals, plants and humans?
Air pollution can hurt animals and humans when they
inhale contaminated air. It can cause respiratory
problems as well as other health effects if
contaminants are absorbed from the lungs into other
parts of the body. Certain air contaminants can hurt
animals and humans when they contact the skin.
Plants rely on respiration for their growth and can also
be hurt by exposure to contaminants in the air.
How can we clean it up?
The most effective approach for cleaning up air
pollution is to prevent contaminants from being
emitted at dangerous levels. Air pollution can be
prevented by lowering emissions levels from
automobiles and trucks and switching to more
environmentally friendly commercial products.
Factories that produce hazardous air pollution can
install "scrubbers" or other devices on their
smokestacks to remove contaminants before they enter
the air outside the plant.
